Computer Science Unit 1 Question
and answers rated A+ 2025/2026
Explain the functions of a computer - correct answer ✔A computer is a device that converts raw data
into information using the information processing cycle.
the four steps of the IPC are: Input, processing, storage, and output. Computers ca be programmed to
perform different tasks.
List the various types and characteristics of multi-user computers. - correct answer ✔Multi-user
computers allow multiple simultaneous users to connect to the system.
They include servers, mid-range servers, mainframe computers, and enterprise servers.
Supercomputers perform complex mathematical calculations. They perform a limited number of tasks as
quickly as possible.
Distributed computing uses the processing of multiple computers to perform complex tasks.
Give example of other personal computing devices. - correct answer ✔Smartphones, wearable, GPS,
video game systems and simulators.
List the various types and characteristics of personal computers - correct answer ✔Personal computers
include desktop computers, which offer the most speed, power and upgrade-ability for the lowest cost;
Workstations, which are high-end desktop computers;
all-in-ones which are compact desktop computers with the computer case integrated into the monitor.
Portable personal computers include notebooks and tablets.
Describe now computers represent data using Binary Codes - correct answer ✔A single bit (or switch)
has two possible states -on or off- and can be used for situations with two possibilities such as yes/no or
true/false.
Digital data is represented by 8-bit binary code on most modern computers. The 8-bit ASCII system
originally had binary codes for 256 characters.
