Software

• What is system software?

  It is the interface between computer hardware and user application programs.
• What is the primary function of system software?

  It enables the computer to operate hardware and application software.
• What does application software do?

  It enables the computer to perform a particular task, such as word processing.
• What is an operating system?

  It manages all other programs being used on the computer.
• Give an example of an operating system.

  Windows
• How does an operating system manage memory?

  It locates free memory space in RAM and allocates it to programs or file data.
• What technique does an operating system use to allocate processing time to programs?

  It uses techniques such as time slicing.
• What are utility programs?

  Programs that perform maintenance tasks such as disk defragmentation and data backup.
• What is the purpose of disk defragmentation?

  To organize fragmented data on a disk to improve access speed.
• What is task scheduling in computing?

  It divides processor time among multiple tasks to maximize efficiency.
• What is data backup?

  A copy of the original data or file in case it gets damaged or lost.
• Where should data backups be stored?

  In a secure location, such as a hard drive or data servers.
• What is the purpose of anti-virus software?

  To scan files on a computer and detect viruses using a database of known threats.
• Why is it important to update anti-virus software?

  To ensure it can detect new and emerging viruses.
• What is multiuser processing?

  A mode of processing where many users share the resources of a powerful computer.
• What is time-sharing in computing?

  It is when an operating system switches between users at high speed to allocate processor time.
• What is the aim of task scheduling?

  To make maximum use of processor time and improve system efficiency.
• What is data mining?

  Searching and analyzing large batches of raw data to identify patterns.
• What does volume refer to in data storage?

  The amount of data stored in a database.
• What does variety refer to in data storage?

  Different types of data stored in various formats.
• What does velocity refer to in data processing?

  The speed at which data can be processed.
• Why are powerful computers necessary for processing large volumes of data?

  To process data more quickly and efficiently.
