How to Convert FAT to NTFS file system

To convert a FAT partition to NTFS, perform the following steps.

Click Start, click Programs, and then click Command Prompt.

In Windows XP, click Start, click Run, type cmd and then click OK.

At the command prompt, type CONVERT [driveletter]: /FS:NTFS.

Convert.exe will attempt to convert the partition to NTFS.

NOTE: Although the chance of corruption or data loss during the conversion from FAT to NTFS is minimal, it is best to perform a full backup of the data on the drive that it is to be converted prior to executing the convert command. It is also recommended to verify the integrity of the backup before proceeding, as well as to run RDISK and update the emergency repair disk (ERD).


AVI File Fix in Windows XP

If you have any AVI files that you saved in Windows 9x, which have interference when opened in Windows XP, there is an easy fix to get rid of the interference: Open Windows Movie Maker. Click View and then click Options. Click in the box to remove the check mark beside Automatically create clips. Now, import the movie file that has interference and drag it onto the timeline. Then save the movie, and during the re-rendering, the interference will be removed.


Mustek 600 CP scanner or other software unable to install on XP

If you have a piece of software that refuses to install because it says that you are not running Windows 2000 (such as the Win2K drivers for a Mustek scanner!!) you can simply edit

HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows NT/CurrentVersion/ProductName

to say Microsoft Windows 2000 instead of XP and it will install. You may also have to edit the version number or build number, depending on how hard the program tries to verify that you are installing on the correct OS. I had to do this for my Mustek 600 CP scanner (compatibility mode didn't help!!!) and it worked great, so I now have my scanner working with XP (and a tech at Mustek can now eat his words). BTW, don't forget to restore any changes you make after you get your software installed.

NTFS vs. FAT

To NTFS or not to NTFS—that is the question. But unlike the deeper questions of life, this one isn't really all that hard to answer. For most users running Windows XP, NTFS is the obvious choice. It's more powerful and offers security advantages not found in the other file systems. But let's go over the differences among the files systems so we're all clear about the choice. There are essentially three different file systems available in Windows XP: FAT16, short for File Allocation Table, FAT32, and NTFS, short for NT File System.

FAT16
The FAT16 file system was introduced way back with MS–DOS in 1981, and it's showing its age. It was designed originally to handle files on a floppy drive, and has had minor modifications over the years so it can handle hard disks, and even file names longer than the original limitation of 8.3 characters, but it's still the lowest common denominator. The biggest advantage of FAT16 is that it is compatible across a wide variety of operating systems, including Windows 95/98/Me, OS/2, Linux, and some versions of UNIX. The biggest problem of FAT16 is that it has a fixed maximum number of clusters per partition, so as hard disks get bigger and bigger, the size of each cluster has to get larger. In a 2–GB partition, each cluster is 32 kilobytes, meaning that even the smallest file on the partition will take up 32 KB of space. FAT16 also doesn't support compression, encryption, or advanced security using access control lists.

FAT32
The FAT32 file system, originally introduced in Windows 95 Service Pack 2, is really just an extension of the original FAT16 file system that provides for a much larger number of clusters per partition. As such, it greatly improves the overall disk utilization when compared to a FAT16 file system. However, FAT32 shares all of the other limitations of FAT16, and adds an important additional limitation—many operating systems that can recognize FAT16 will not work with FAT32—most notably Windows NT, but also Linux and UNIX as well. Now this isn't a problem if you're running FAT32 on a Windows XP computer and sharing your drive out to other computers on your network—they don't need to know (and generally don't really care) what your underlying file system is.

The Advantages of NTFS
The NTFS file system, introduced with first version of Windows NT, is a completely different file system from FAT. It provides for greatly increased security, file–by–file compression, quotas, and even encryption. It is the default file system for new installations of Windows XP, and if you're doing an upgrade from a previous version of Windows, you'll be asked if you want to convert your existing file systems to NTFS.

Don't worry. If you've already upgraded to Windows XP and didn't do the conversion then, it's not a problem. You can convert FAT16 or FAT32 volumes to NTFS at any point.

Just remember that you can't easily go back to FAT or FAT32 (without reformatting the drive or partition), not that I think you'll want to.

The NTFS file system is generally not compatible with other operating systems installed on the same computer, nor is it available when you've booted a computer from a floppy disk. For this reason, many system administrators, myself included, used to recommend that users format at least a small partition at the beginning of their main hard disk as FAT. This partition provided a place to store emergency recovery tools or special drivers needed for reinstallation, and was a mechanism for digging yourself out of the hole you'd just dug into. But with the enhanced recovery abilities built into Windows XP (more on that in a future column), I don't think it's necessary or desirable to create that initial FAT partition.

When to Use FAT or FAT32
If you're running more than one operating system on a single computer, you will definitely need to format some of your volumes as FAT. Any programs or data that need to be accessed by more than one operating system on that computer should be stored on a FAT16 or possibly FAT32 volume. But keep in mind that you have no security for data on a FAT16 or FAT32 volume—any one with access to the computer can read, change, or even delete any file that is stored on a FAT16 or FAT32 partition. In many cases, this is even possible over a network. So do not store sensitive files on drives or partitions formatted with FAT file systems.


Make your Folders Private

•Open My Computer
•Double-click the drive where Windows is installed (usually drive (C:), unless you have more than one drive on your computer).
•If the contents of the drive are hidden, under System Tasks, click Show the contents of this drive.
•Double-click the Documents and Settings folder.
•Double-click your user folder.
•Right-click any folder in your user profile, and then click Properties.
•On the Sharing tab, select the Make this folder private so that only I have access to it check box.

Note

•To open My Computer, click Start, and then click My Computer.
•This option is only available for folders included in your user profile. Folders in your user profile include My Documents and its subfolders, Desktop, Start Menu, Cookies, and Favorites. If you do not make these folders private, they are available to everyone who uses your computer.
•When you make a folder private, all of its subfolders are private as well. For example, when you make My Documents private, you also make My Music and My Pictures private.

When you share a folder, you also share all of its subfolders unless you make them private.
•You cannot make your folders private if your drive is not formatted as NTFS For information about converting your drive to NTFS

WINDOWS XP TIPS & TRICKS 103

Search For Hidden Or System Files In Windows XP

The Search companion in Windows XP searches for hidden and system files differently than in earlier versions of Windows. This guide describes how to search for hidden or system files in Windows XP.

Search for Hidden or System Files By default, the Search companion does not search for hidden or system files. Because of this, you may be unable to find files, even though they exist on the drive.

To search for hidden or system files in Windows XP:
Click Start, click Search, click All files and folders, and then click More advanced options.

Click to select the Search system folders and Search hidden files and folders check boxes.

NOTE: You do not need to configure your computer to show hidden files in the Folder Options dialog box in Windows Explorer to find files with either the hidden or system attributes, but you need to configure your computer not to hide protected operating system files to find files with both the hidden and system attributes. Search Companion shares the Hide protected operating system files option (which hides files with both the system and hidden attributes) with the Folder Options dialog box Windows Explorer.


Restricting Logon Access

If you work in a multiuser computing environment, and you have full (administrator level) access to your computer, you might want to restrict unauthorized access to your "sensitive" files under Windows 95/98.
One way is to disable the Cancel button in the Logon dialog box.
Just run Regedit and go to:

HKEY_LOCAL_MACHINE/Network/Logon

Create the "Logon" subkey if it is not present on your machine: highlight the Network key -> right-click in the left hand Regedit pane -> select New -> Key -> name it "Logon" (no quotes) -> press Enter. Then add/modify a DWORD value and call it "MustBeValidated" (don't type the quotes). Double-click it, check the Decimal box and type 1 for value.
Now click the Start button -> Shut Down (Log off UserName) -> Log on as a different user, and you'll notice that the Logon Cancel button has been disabled.


Remove the Recycle Bin from the Desktop

If you don't use the Recycle Bin to store deleted files , you can get rid of its desktop icon all together.

Run Regedit and go to:

HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/
Windows/CurrentVersion/explorer/Desktop/NameSpace


Click on the "Recycle Bin" string in the right hand pane. Hit Del, click OK.


How to Rename the Recycle Bin

To change the name of the Recycle Bin desktop icon, open Regedit and go to:

HKEY_CLASSES_ROOT/CLSID/
{645FF040-5081-101B-9F08-00AA002F954E}

and change the name "Recycle Bin" to whatever you want (don't type any quotes).


Provide Remote Assistance When Using a NAT Device

You can provide Remote Assistance to a friend who uses a Network Address Translation (NAT) device by modifying the Remote Assistance invitation using XML. Network Address Translation is used to allow multiple computers to share the same outbound Internet connection. To open a Remote Assistance session with a friend who uses a NAT device:

1. Ask your friend to send you a Remote Assistance invitation by e–mail.
2. Save the invitation file to your desktop.
3. Right–click the file, and then click Open With Notepad. You'll see that the file is a simple XML file.
4.Under the RCTICKET attribute is a private IP address, such as 192.168.1.100.
5. Over–write this IP address with your friend's public IP address. Your friend must send you his or her public IP address: they can find out what it is by going to a Web site that will return the public IP address, such as http://www.dslreports.com/ip.
6. Save the file, and then double–click it to open the Remote Assistance session.

Now, you'll be able to connect and provide them with the help they need. So that your inbound IP connection is routed to the correct computer, the NAT must be configured to route that inbound traffic. To do so, make sure your friend forwards port 3389 to the computer they want help from.

Speed up your browsing of Windows 2000 & XP machines

Here's a great tip to speed up your browsing of Windows XP machines. Its actually a fix to a bug installed as default in Windows 2000 that scans shared files for Scheduled Tasks. And it turns out that you can experience a delay as long as 30 seconds when you try to view shared files across a network because Windows 2000 is using the extra time to search the remote computer for any Scheduled Tasks. Note that though the fix is originally intended for only those affected, Windows 2000 users will experience that the actual browsing speed of both the Internet & Windows Explorers improve significantly after applying it since it doesn't search for Scheduled Tasks anymore. Here's how :

Open up the Registry and go to :

HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/Current Version/Explorer/RemoteComputer/NameSpace

Under that branch, select the key :

{D6277990-4C6A-11CF-8D87-00AA0060F5BF}

and delete it.

This is key that instructs Windows to search for Scheduled Tasks. If you like you may want to export the exact branch so that you can restore the key if necessary.

This fix is so effective that it doesn't require a reboot and you can almost immediately determine yourself how much it speeds up your browsing processes.


Set up and Use Internet Connection Sharing

With Internet Connection Sharing (ICS) in Windows XP, you can connect one computer to the Internet, then share the Internet service with several computers on your home or small office network. The Network Setup Wizard in Windows XP Professional will automatically provide all of the network settings you need to share one Internet connection with all the computers in your network. Each computer can use programs such as Internet Explorer and Outlook Express as if they were directly connected to the Internet.

You should not use this feature in an existing network with Windows 2000 Server domain controllers, DNS servers, gateways, DHCP servers, or systems configured for static IP addresses.


Enabling ICS

The ICS host computer needs two network connections. The local area network connection, automatically created by installing a network adapter, connects to the computers on your home or small office network. The other connection, using a 56k modem, ISDN, DSL, or cable modem, connects the home or small office network to the Internet. You need to ensure that ICS is enabled on the connection that has the Internet connection. By doing this, the shared connection can connect your home or small office network to the Internet, and users outside your network are not at risk of receiving inappropriate addresses from your network.

When you enable ICS, the local area network connection to the home or small office network is given a new static IP address and configuration. Consequently, TCP/IP connections established between any home or small office computer and the ICS host computer at the time of enabling ICS are lost and need to be reestablished. For example, if Internet Explorer is connecting to a Web site when Internet Connection Sharing is enabled, refresh the browser to reestablish the connection. You must configure client machines on your home or small office network so TCP/IP on the local area connection obtains an IP address automatically. Home or small office network users must also configure Internet options for Internet Connection Sharing. To enable Internet Connection Sharing (ICS) Discovery and Control on Windows 98, Windows 98 Second Edition, and Windows Millennium Edition computers, run the Network Setup Wizard from the CD or floppy disk on these computers. For ICS Discovery and Control to work on Windows 98, Windows 98 Second Edition, and Windows Millennium Edition computers, Internet Explorer version 5.0 or later must be installed.

To enable Internet Connection Sharing on a network connection

You must be logged on to your computer with an owner account in order to complete this procedure.
Open Network Connections. (Click Start, click Control Panel, and then double–click Network Connections.)

Click the dial–up, local area network, PPPoE, or VPN connection you want to share, and then, under Network Tasks, click Change settings of this connection.

On the Advanced tab, select the Allow other network users to connect through this computer's Internet connection check box.
If you want this connection to dial automatically when another computer on your home or small office network attempts to access external resources, select the Establish a dial–up connection whenever a computer on my network attempts to access the Internet check box.

If you want other network users to enable or disable the shared Internet connection, select the Allow other network users to control or disable the shared Internet connection check box.

Under Internet Connection Sharing, in Home networking connection, select any adapter that connects the computer sharing its Internet connection to the other computers on your network. The Home networking connection is only present when two or more network adapters are installed on the computer.

To configure Internet options on your client computers for Internet Connection Sharing

Open Internet Explorer. Click Start, point to All Programs, and then click Internet Explorer.)

On the Tools menu, click Internet Options.

On the Connections tab, click Never dial a connection, and then click LAN Settings.

In Automatic configuration, clear the Automatically detect settings and Use automatic configuration script check boxes.

In Proxy Server, clear the Use a proxy server check box.


Set Processes Priority

Follow this tip to increase the priority of active processes, this will result in prioritisation of processes using the CPU.

CTRL-SHIFT-ESC

1.Go to the second tab called Processes, right click on one of the active processes, you will see the Set Priority option


2.For example, your Run your CDwriter program , set the priority higher, and guess what, no crashed CD’s


Set Permissions for Shared Files and Folders

Sharing of files and folders can be managed in two ways. If you chose simplified file sharing, your folders can be shared with everyone on your network or workgroup, or you can make your folders private. (This is how folders are shared in Windows 2000.) However, in Windows XP Professional, you can also set folder permissions for specific users or groups. To do this, you must first change the default setting, which is simple file sharing. To change this setting, follow these steps:

•Open Control Panel, click Tools, and then click Folder Options.
•Click the View tab, and scroll to the bottom of the Advanced Settings list.
•Clear the Use simple file sharing (Recommended) check box.
•To manage folder permissions, browse to the folder in Windows Explorer, right–click the folder, and then click Properties. Click the Security tab, and assign permissions, such as Full Control, Modify, Read, and/or Write, to specific users.

You can set file and folder permissions only on drives formatted to use NTFS, and you must be the owner or have been granted permission to do so by the owner.

WINDOWS XP TIPS & TRICKS 101

How to Remove Windows XP's Messenger

Theoretically, you can get rid of it (as well as a few other things). Windows 2000 power users should already be familiar with this tweak.

Fire up the Windows Explorer and navigate your way to the %SYSTEMROOT% \ INF folder. What the heck is that thingy with the percentage signs? It's a variable. For most people, %SYSTEMROOT% is C:\Windows. For others, it may be E:\WinXP. Get it? Okay, on with the hack! In the INF folder, open sysoc.inf (but not before making a BACKUP copy first). Before your eyes glaze over, look for the line containing "msmsgs" in it. Near the end of that particular line, you'll notice that the word "hide" is not so hidden. Go ahead and delete "hide" (so that the flanking commas are left sitting next to one another). Save the file and close it. Now, open the Add and Remove Programs applet in the Control Panel. Click the Add / Remove Windows Components icon. You should see "Windows Messenger" in that list. Remove the checkmark from its box, and you should be set. NOTE: there are other hidden system components in that sysoc.inf file, too. Remove "hide" and the subsequent programs at your own risk.


Set the Search Screen to the Classic Look

When I first saw the default search pane in Windows XP, my instinct was to return it to its classic look; that puppy had to go. Of course, I later discovered that a doggie door is built into the applet. Click "Change preferences" then "Without an animated screen character." If you'd rather give it a bare-bones "Windows 2000" look and feel, fire up your Registry editor and navigate to:

HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Explorer \ CabinetState.

You may need to create a new string value labeled "Use Search Asst" and set it to "no".


New Sound Blaster Drivers

With the loads of problems reported by users with Soundblaster cards on Windows XP Creative has stepped up and offered drivers for at least some models of their Sound Blaster cards, but check your particular model closely. I have downloaded the SB128 drivers and my sound problems have been resolved..! So they do work.

Upgrading to Windows XP

You can upgrade a computer that runs Windows 98, 98SE, or Me to Windows XP Home Edition. Those same versions, along with Windows NT Workstation 4.0 and Windows 2000 Professional, can be upgraded to Windows XP Professional.

(1).To ensure a smooth upgrade and avoid networking problems, follow these tips before starting the upgrade:

(2)Install all network cards. XP will detect them and automatically install the right drivers.

(3)Have your Internet connection available. The XP setup process will connect to a Microsoft server to download the latest setup files, including changes that have been made since XP was released.

Some programs are incompatible with XP and can cause networking problems. Un-install these programs. After the upgrade is complete and the network is working, re-install XP-compatible versions of these programs: Internet Connection Sharing, NAT, Proxy Server Anti-Virus Firewall.


How to Upgrade Windows 98 or Windows Millennium Edition Profiles to Windows XP Domain User Profiles

This guide describes how to upgrade a Microsoft Microsoft Windows 98-based, or Microsoft Windows Millennium Edition-based client that has user profiles to a Microsoft Windows XP-based client.

The following steps enable the Windows 98 and Windows Millennium Edition (Me) profiles to be retained throughout the process.

Your best method to retain the profiles is to join the domain during the upgrade installation process.

Otherwise, you must use a workaround method to transfer the profile information over to the Windows XP profile.

During the upgrade installation process, at the networking section, the administrator is offered the choice to join a domain or a workgroup.

If you join the domain at this juncture, you ensure that all the existing profiles are migrated successfully to the Windows XP-based installation.

If you did not join the computer to the domain during the upgrade process, you must use the following workaround method:

Join the upgraded computer to the target domain.

All applicable users must log on and log off (which generates a profile).

Copy the appropriate Application Data folder from the Windows 95, Windows 98, and Windows Me profiles to the newly created user profiles.

MOUSE AND KEYBOARD

The mouse and keyboard are also component of your computer. Mouse is a pointing device that functions by detecting two-dimensional motion relative to its supporting surface. Physically, a mouse consists of a small case, held under one of the user's hands, with one or more buttons. It sometimes features other elements, such as "wheels or laser lights”, which allow the user to perform various system-dependent operations, or extra buttons or features can add more control or dimensional input. The mouse's motion typically translates into the motion of a pointer on a display, which allows for fine control of a Graphical User Interface.

While Keyboard is a peripheral partially modeled after the typewriter keyboard. Physically, a keyboard is an arrangement of buttons, or keys. A keyboard typically has characters engraved or printed on the keys; in most cases, each press of a key corresponds to a single written symbol. However, to produce some symbols requires pressing and holding several keys simultaneously or in sequence; other keys do not produce any symbol, but instead affect the operation of the computer or the keyboard itself. A majority of all keyboard keys produce letters, numbers or signs (characters) that are appropriate for the operator's language. Other keys can produce actions when pressed, and other actions are available by the simultaneous pressing of more than one action key.

In choosing a keyboard or a mouse, I suggest that you choose a device that is comfortable for you to use. For me, maximizing a user potential is also a factor for you to consider in choosing a PC device such as mouse and keyboard.

Hey fellow PC addicts, check this out! I have found a product catalogue for a keyboard and mouse. Hope it will help you in choosing or upgrading your keyboard and mouse device.

PC MONITOR

The monitor is another component of your computer. The text and images generated by your computer are displayed on its screen. There are two types of monitor for a desktop computer.

1. CRT Monitor – cathode ray tube (CRT) is an evacuated glass envelope containing an electron gun (a source of electrons) and a fluorescent screen, usually with internal or external means to accelerate and deflect the electrons. When electrons strike the fluorescent screen, light is emitted. The electron beam is deflected and modulated in a way which causes it to display an image on the screen. The image may represent electrical waveforms (oscilloscope), pictures (television, computer monitor), echoes of aircraft detected by radar, etc. CRT screens have much deeper cabinets compared to LCD screens for a given area. They can, however, display higher resolutions on a smaller screen. Also, LCDs have worse color rendition due to the fluorescent lights used as backlights, even though they can be brighter overall. The result is that CRTs are useful for displaying photos with high pixels per unit area and correct color balance, and for having large desktop area concentrated into a small screen. Having 1600 × 1200 resolution in 18 inch 4:3 rather than 20–24 inch on most LCDs also allows less eye movement to view different parts of the screen. In addition to offering high-resolutions in a smaller screen area, they offer the resolutions more cheaply for a given resolution. In general, rear-projection displays and LCDs require less power per display area, but plasma displays consume as much as or more than CRTs. However, CRTs still find adherents in computer gaming because of higher resolution per initial cost and small response time. CRTs are often used in psychological research that requires precise recording of reaction times. CRTs are also still popular in the printing and broadcasting industries as well as in the professional video, photography, and graphics fields due to their greater color fidelity and contrast, better resolution when displaying moving images, and better view from angles, although improvements in LCD technology increasingly alleviate these concerns.

2. LCD Monitor – A thin film transistor liquid crystal display (TFT-LCD) is a variant of liquid crystal display (LCD) which uses thin film transistor (TFT) technology to improve image quality. TFT LCD is one type of active matrix LCD, though it is usually synonymous with LCD. It is used in televisions, flat panel displays and projectors. Being slim and compact is one of the advantages of a LCD monitor. However, it is much expensive as compared to CRT.

PC HARDWARE

Yes, computer being assembled even by you makes computers nowadays affordable. But you’re maybe wondering, how can I assemble my own computer? In this case, computer knowledge most especially on the PC’s hardware aspect is needed to be able for you to assemble or customize your desire PC. For beginners, let me first give you an idea about computer hardware.

A computer set includes a variety of components; one of the most important of these is the System Units.

It houses your motherboard, video card, hard disk, optical disc drive, and other internal parts of your computer.

1. Motherboard – the most important components of the computer. At one point or another, every other component connects to the motherboard. It is the largest board of the computer system. Typically, the motherboard contains the CPU, BIOS, memory, mass storage interfaces, serial and parallel ports, expansion slots and controllers required to control standard peripheral devices, such as the display screen, keyboard, and disk drive. Collectively, all these chips that reside on the motherboard are known as the motherboard’s chipset.

2. CPU (Central Processing Unit) – The CPU is the computer’s brain. This device does all of the processing within the computer. The popular CPU manufacturers are AMD, Intel, Cyrix and Motorola. CPU speeds are calculated in terms of megahertz, this is known as the clock speed.

3. RAM – Random access memory (usually known by its acronym, RAM) is a type of computer data storage. Today it takes the form of integrated circuits that allow the stored data to be accessed in any order, i.e. at random. The word random thus refers to the fact that any piece of data can be returned in a constant time, regardless of its physical location and whether or not it is related to the previous piece of data. The word RAM is mostly associated with volatile types of memory (such as DRAM memory modules), where the information is lost after the power is switched off. However, many other types of memory are RAM as well (i.e. Random Access Memory), including most types of ROM and a kind of flash memory called NOR-Flash.

4. Power Supply Unit – (Computer PSU) is the component that supplies power to a computer. More specifically, a power supply is typically designed to convert 100-120 V (North America and Japan) or 220-240 V (Europe, Africa, Asia and Australia) AC power from the mains to usable low-voltage DC power for the internal components of the computer. Some power supplies have a switch to change between 230 V and 115 V. Other models have automatic sensors that switch input voltage automatically, or are able to accept any voltage between those limits. The most common computer power supplies are built to conform to the ATX form factor. The most recent specification of the ATX standard is version 2.2, released in 2004. This enables different power supplies to be interchangeable with different components inside the computer. ATX power supplies also are designed to turn on and off using a signal from the motherboard (PS-ON wire, which can be shorted to ground to turn on the PSU outside the computer), and provide support for modern functions such as the standby mode available in many computers.

5. Video Card – a board that plugs into a personal computer, into the motherboard to be precise, to give it display capabilities. The display capabilities of a computer, however, depend on both the logical circuitry (provided in the video card) and the display monitor. A monochrome monitor, for example, cannot display color no matter how powerful the video adapter. Modern video adapters contain memory, so adapters contain memory, so that the computer’s RAM is not used for storing displays. In addition, most adapters have their own graphics coprocessor for performing graphics calculations. These adapters often called Graphics Accelerators. Video Card is also called video adapter, video board, video display board, graphics card and graphics adapter.

Today there are motherboards with built-in video card. Although video graphics of this built-in video card is not so powerful as compared to a high-end video card, still produces desirable graphics. Advantage of this built-in video card is that it lessens your cost because it is already installed in the motherboard, however, it uses some of the memory of your computer’s RAM and that it’s disadvantage.

6. Hard Disk – a hard disk stores the files and programs in your computer. It is permanently connected to your computer. Today an ordinary hard disk can store up to 80 gigabytes of information.

7. Optical Disc Drive – an optical disc drive (ODD) is a disk drive that uses laser light or electromagnetic waves near the light spectrum as part of the process of reading and writing data. It is a computer's peripheral device that stores data on optical discs. Some drives can only read from discs, but commonly drives are both readers and recorders. Recorders are sometimes called burners or writers. Common media and technology families include CD, DVD, and Blu-ray Disc.

8. 3 ½ Floppy Disk Drive – is a data storage medium that is composed of a disk of thin, flexible ("floppy") magnetic storage medium encased in a square or rectangular plastic shell. Floppy disks are read and written by a floppy disk drive or FDD, the initials of which should not be confused with "fixed disk drive", which is another term for a hard disk drive.

The monitor, printer, keyboard, mouse, external speaker, AVR / UPS and external modem are other components of a computer aside from the System Unit. To be able to assemble or upgrade your own PC, computer hardware knowledge particularly in the System Unit is more important to acknowledge.

COMPUTERS NOW

Before having a Personal Computer at home is not an essential thing for most of us. Why? It's simple because of the high price during that time. I remember that was in the year 90's, when a low-end Personal Computer cost 30,000 pesos. Well that's depend on the computer brand and specs, not mentioning that it is only a desktop computer. So you're maybe wondering how much is a Laptop Computer that time? I saw an Acer Laptop Computer when I'm strolling at SM Megamall, a whopping 100,000 pesos is the price, WOW! But now, it's a different thing, due to the uprising need of internet as a mean for information and communication. The demand for computers also increases. Computers nowadays can be assembled depending on the user’s need and budget. And this makes a big different, making computer affordable to most people.
