  1. Counterculture

  2. Legacy database

  3. Black box

  4. Database schema

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

This device is a system or an object which can be viewed solely in terms of its input/output and transfer characteristics without any knowledge of its internal workings.

Multiple choice

A system using an automated work cell controlled by electronic signals from a common centralised computer facility is called

  1. adaptive control system

  2. robotics

  3. flexible manufacturing system (FMS)

  4. automatic guided vehicle (AGV) system

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

FMS is defined as a system where automated work cells receive electronic control signals from a central computer. This central coordination enables multiple machines to work together flexibly. Options A, B, and D are incorrect: adaptive control is a feedback mechanism, robotics refers to individual robots, and AGVs are only for material transport.

Multiple choice

Compared to a manual system, the consequences of an error in a computerized system are more serious due to the fact that

(a) errors being generated at high speed will involve higher cost to correct them (b) computer system processes more data (c) users of computer systems perceive the computer output to be always correct

  1. (a) to (c) all

  2. Only (b) and (c)

  3. Only (a) and (b)

  4. Only (a)

All of the above reasons are correct.

Multiple choice

The hardware configuration consisting of a keyboard and monitor that is capable of sending and receiving information, but has no memory or processing capability is called

  1. server

  2. workstation

  3. dumb terminal

  4. node
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A dumb terminal is a computer terminal that consists mostly of just a display monitor and a keyboard (and perhaps a mouse as well). It has no internal CPU (central processing unit) and thus, has little or no processing power.

  1. workshops

  2. system software

  3. application software

  4. real time software

  5. business software
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

 Yes, device drivers are an example of system software.

Multiple choice

The Intel Pentium bug/flaw was an issue with the

  1. Cache

  2. FPU

  3. Socket

  4. There was no bug/flaw
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The Intel Pentium bug (1994) was a floating-point division error in the processor's Floating Point Unit (FPU). The bug caused incorrect results for certain division operations. Cache is memory storage. Socket is the processor interface. The bug definitely existed and was a major issue for Intel.

Multiple choice

What is degauss?

  1. Attachment for CPU

  2. Creating magnetic media

  3. Erasing magnetic media

  4. Medical software
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Degaussing is the process of reducing or eliminating magnetic fields. It is used to erase magnetic media like floppy disks, hard drives, and to demagnetize CRT monitors. It is not a CPU attachment, medical software, or method for creating magnetic media.
