Worked practice questions

Data in a network is divided into smaller chunks called:

  1. Packets
  2. Pockets
  3. Puckers
  4. Pickets
Show answer and solution

Correct answer: A. Packets

1. A whole file is not sent across a network in one piece. 2. It is broken up before being carried. 3. For communication, data in a network is divided into smaller chunks called packets. 4. So the answer is packets. _Source: syllabus Computer Science, Ch 10 'Computer Networks'_

The arrangement of computers and peripherals in a network is called its:

  1. Terminology
  2. Topology
  3. Typology
  4. Tautology
Show answer and solution

Correct answer: B. Topology

1. Networks differ in how their machines are laid out. 2. That layout has a name of its own. 3. The arrangement of computers and other peripherals in a network is called its topology. 4. So the answer is topology. _Source: syllabus Computer Science, Ch 10 'Computer Networks'_

Modem stands for modulator and:

  1. Decorator
  2. Denominator
  3. Demodulator
  4. Decelerator
Show answer and solution

Correct answer: C. Demodulator

1. The name of the device is a contraction of two words. 2. The first half is modulator. 3. Modem stands for MOdulator DEModulator. 4. So the second half is demodulator. _Source: syllabus Computer Science, Ch 10 'Computer Networks'_
