Question 1

Question
What is a computer program?
Answer
  • A) A sequence of instructions that enables a computer to do something.
  • B) A sequence of messages that tells a computer to do something.
  • C)A video game

  • B) 42
  • C) 36

Question 3

Answer
  • True
  • False

Question 4

Question
ASCII (American [blank_start]Standard[blank_end] Code for [blank_start]Information Interchange[blank_end]) is the most common format for text files in computers and on the Internet. In an ASCII file, each alphabetic, [blank_start]numeric,[blank_end] or special character is represented with a [blank_start]7[blank_end]-bit binary number (a string of [blank_start]seven[blank_end] 0s or 1s). [blank_start]128[blank_end] possible characters are defined.
Answer
  • Standard
  • Stationary
  • Information Interchange
  • Interchange Information
  • interger
  • numeric,
  • 7
  • 8
  • seven
  • eight
  • 128
  • 164

Question 5

Question
Tick all of the topologies... (please).
Answer
  • Bus
  • Car
  • Ring
  • Ster
  • Star
  • Tulip

Question 6

Question
Most programs are developed using [blank_start]programming languages[blank_end]. These languages have specific [blank_start]syntax[blank_end] that must be used so that the program will run properly. Pseudocode is [blank_start]not a[blank_end] programming language, it is a simple way of describing a set of [blank_start]instructions[blank_end] that does not have to use specific syntax.

Question 7

Question
An [blank_start]algorithm[blank_end] is a plan, a logical step-by-step process for solving a problem. Algorithms are normally written as a [blank_start]flowchart[blank_end] or in pseudocode.
Answer
  • algorithm

  • Structured Query Language
  • Structured Queer Language

Question 11

Question
SDLC stands for software development life cycle...
Answer
  • True
  • False

Question 12

Question
A code where each number represents a character can be used to convert text into [blank_start]binary[blank_end]. One code we can use for this is called [blank_start]ASCII[blank_end]. The ASCII code takes each character on the keyboard and assigns it a binary number. Text characters start at denary number [blank_start]0[blank_end] in the ASCII code, but this covers special characters including punctuation, the return key and control characters as well as the number keys, capital letters and lower case letters. ASCII code can only store [blank_start]128[blank_end] characters, which is enough for most words in English but not enough for other languages. If you want to use accents in European languages or larger alphabets such as Cyrillic (the [blank_start]Russian[blank_end] alphabet) and Chinese Mandarin then more characters are needed. Therefore another code, called [blank_start]Unicode[blank_end], was created. This meant that computers could be used by people using different languages.
