Differentiate between a computer virus and a computer worm as used in computers.(4 marks)July 2020
A computer virus is a type of malicious software that is designed to replicate itself and spread from one computer to another. It can infect a computer by attaching itself to a program or file and then activating when the program or file is opened. Once a virus has infected a computer, it can perforRead more
A computer virus is a type of malicious software that is designed to replicate itself and spread from one computer to another. It can infect a computer by attaching itself to a program or file and then activating when the program or file is opened. Once a virus has infected a computer, it can perform various actions, such as deleting files, stealing personal information, or displaying unwanted messages.
A computer worm, on the other hand, is a type of malware that is designed to replicate itself and spread over networks, without requiring a host program or file. It can propagate itself through vulnerabilities in networked systems, such as unpatched software or weak passwords. Like a virus, a worm can perform various actions once it has infected a computer, such as deleting files or stealing personal information.
One key difference between a virus and a worm is the way in which they spread. A virus spreads by attaching itself to a host program or file, while a worm spreads independently over networks. Another difference is that a virus requires some form of human interaction (such as opening an infected file) to spread, while a worm can propagate itself automatically.

Distinguish between line spacing and na Spacing as used in a word processing document.(4 marks)July 2020
Line spacing refers to the amount of vertical space between lines of text in a word processing document. It is measured in points or as a multiple of the font size. For example, if the font size is 12 points and the line spacing is set to double spacing, the vertical space between lines of text willRead more
Line spacing refers to the amount of vertical space between lines of text in a word processing document. It is measured in points or as a multiple of the font size. For example, if the font size is 12 points and the line spacing is set to double spacing, the vertical space between lines of text will be 24 points. Line spacing can be adjusted to make a document more legible or to fit more text on a page.
Character spacing, on the other hand, refers to the amount of horizontal space between characters in a word processing document. It is also measured in points and can be adjusted to make text more legible or to fit more text on a line. Increasing character spacing can help to improve readability for people with visual impairments, or to make text stand out in a document. However, it is important to use character spacing sparingly, as excessive character spacing can make text difficult to read and disrupt the overall look of the document.

(i) Status bar: The status bar is a horizontal bar that appears at the bottom of a word processing document. It displays information about the current document, such as the page number, the word count, and the language being used. It may also contain buttons for common actions, such as saving the document or printing it.
(ii) Menubar: The menubar is a horizontal bar that appears at the top of a word processing document. It contains a list of menus with options for formatting, editing, and performing other actions on the document. For example, the “File” menu may contain options for saving, printing, and opening new documents, while the “Edit” menu may contain options for cutting, copying, and pasting text.
