Computer Systems
The hardest questions are often those about Computer Systems - that's where you need to know your jargon. Computer Systems includes hardware (input, storage and output devices), low level machine (how data is stored), operating systems and translator programs.
You should be able to state what each of these abbreviations stands for, and write a sentence about what it means:
ASCII, ALU, CAD, CAM, CD-ROM, CPU, DTP, EFT, EPOS, GIGO, GUI, HCI, HTML, LAN, LCD, MICR, OCR, POS, RAM, ROM, RTF, TFT, VDU, WAN, WIMP and WWW.
Check that you can separate the meanings of these confusing pairs (or triplets):
validation and verification
compiler and interpreter
RAM and ROM
CD-ROM, CD-R and CD-RW
sequential and direct access
LAN and WAN
A-to-D and D-to-A conversion
on-line and off-line
WWW and the Internet
analogue and digital
data and information
How wide is you knowledge of computer hardware? See if you can list (and give an example use for) ....
* 10 input devices
* 3 types of printer
* 3 types of display
* 10 storage devices
Any questions?
