Several things are necessary to make a PC into a Multimedia class of PC:
1) At least an 80386DX CPU, preferably an 80486DX CPU. 

2) An SVGA class video card, usually a high-performance card;

3) A CD-ROM drive, at least a double-speed drive that is XA-ready, Kodak Photo CD ready, and has at least a 300KBsustained data transfer rate;

4) A sound card of some kind, one that is Sound Blaster/AdLib compatible (I STRONGLY recommend a true Creative Labs Sound Blaster card - no clones);

5) Windows 3.1, OS/2, Windows NT, or some operating system/environment that will access and use CD-ROM drives and configure for sound cards.

6) In a DOS environment, you must load the DOS program MSCDEX.EXE, which enables MS-DOS to utilize a CD-ROM.

7) In a DOS environment, you must load a driver program for your sound card so that it will work with DOS. Some sound cards have drivers that work EXCLUSIVELY with Windows, and NOT in DOS.

8) A mouse, to make the graphical environment of Windows or OS/2 easier to use.



For the most part, your computer will operate on a LAN just at as it would without a LAN. You will log onto a disk drive (that is actually a network drive), change directories to the place where your application software is located, and execute your program just as you would if the software were on your hard drive inside your PC. Several things will have to happen, though, in order for you to gain access to your network drive(s):

1) You will have to load and run some kind of driver software that makes your PC able to use the network card plugged into the bus connection inside your PC. This is usually done when DOS loads the driver programs listed in your CONFIG.SYS file.

2) You will need to run the network operating system programs needed to initialize your network card for use by the operating system, identify your PC as a legitimate node on the network, and allow an identified user to log into the network. With Novell Netware, these would be IPX.COM, NETX.COM, and LOGIN.EXE.

3) Your network administrator will have to map specific drive designations to you, grant you rights to access files in the drive and directory, and probably use the capture command to route your print requests to a network printer.

4) You will probably access most of your application software on the network drives with the assistance of a menu program that allows you easy access to your programs and data. Examples could include Novell Main Menu, Direct Access, or Windows. For the most part, everything is the same on a network drive as it is on a local hard drive. DIR gives you a directory of files on your current drive and sub-directory; COPY copies files from one place to another; DEL deletes files; REN renames files. The idea of a network drive is to give you as identical an environment on a network drive as you do on a local hard drive.

Locate a monitor; notice the appearance of the monitor. If the cable has a 9-pin connector, it's either Monochrome, CGA, or EGA. If there is a label with 3-colors on it, then it's probably CGA or EGA. If the monitor has the word "Enhanced" on it, it's probably an EGA monitor.

 Monitor Testing

If the cable has a 15-pin connector, it is a VGA monitor.

Plug the monitor into the appropriate test PC and turn on both the monitor and PC.
Use some kind of software to test the monitor's display capability (Checkit, PC Probe, SYSCHK, etc.)

If the screen displays properly, label the monitor and store it in the appropriate place in the lab.

If the monitor does not display correctly, test and make sure that the monitor is attached to the correct video card.

If the monitor is REALLY DEAD, indicate this on the dead monitor log and dispose of the monitor.

If you need assistance, let someone know.

If you're unsure of whether a monitor is OK or not, label the monitor as such and move on.



Stores large quantities of data for use at a later time. Uses a HARD DISK CONTROLLER to connect hard disk to motherboard. 

Hard Disk Drive

MFM and RLL drives:

Typically have separate controllers and hard disks. RLL controllers can store up to 30% more data on the same disk than MFM controllers. Uses 34-pin AND 20-pin cables to transmit data.

IDE Drives:

Have hard disk controller and hard disk in ONE unit; slightly more difficult to install additional hard disks to IDE systems. Uses 40-pin ribbon cable to transmit data.

SCSI drives:

Uses separate controllers, like MFM & RLL drives, but can transfer data at a much faster rate. SCSI drives are also more expensive. Uses 50-pin or  68-pin cable to transmit data.

How to Easily and Safely Install RAM

How to Easily and Safely Install RAM

Check to see if you have ample light. You may want to have a container to place small screws in. The system unit cover may have small screws and you don't want to lose them.

After you have plenty of work space and ample lighting, prepare your mind as well. Make this and every other adventure of working on your computer educational and fun. Now go over to to familiarize yourself with all components inside the PC. Take the time to study the actual components inside you computer. You'll be glad you did should something go wrong. Follow these steps to install your drive.

Turn off your computer and unplug all peripherals. Take notice of how you unplug or disconnect any devices. Remove the side panel of the tower system or the cover if you have a desktop. Place the panel in a safe place well out of the way. Before touching anything inside the system unit, remove electrical static charge from your body by touching a door knob or any unpainted metal surface.

Remove the new memory from its protective wrapping and locate the sockets to install the new memory chips. Notice the type of retaining clips that hold the chips in place. Remove any old chips you intend to move. Now to be sure you won't damage the chips, ground yourself again to remove any remaining static electricity.
