System Software Flashcards
What is system software?
Software designed to run and manage the computer hardware and provide a platform for application software. Includes operating systems and utility software.
What is the purpose of the operating system (OS)?
The OS manages hardware and software resources, provides a user interface, manages files, and handles memory, processes, and security.
What are the key functions of an operating system?
• User Interface
• Memory Management
• Multitasking
• Peripheral Management
• File Management
• User Management/Security
What is the difference between GUI and CLI?
• GUI (Graphical User Interface): Uses windows, icons, and menus for ease of use.
• CLI (Command Line Interface): Requires typed commands, used by advanced users.
What is utility software?
Software that helps maintain or optimise the computer system, including tools like defragmenters, anti-virus software, and backup programs.
What does disk defragmentation do?
Reorganises fragmented data on a hard drive so files are stored in contiguous blocks — speeds up access time.
What is encryption software?
Software that converts data into a secure, unreadable format to protect it from unauthorised access.
What is backup software?
Software that copies data to prevent loss in case of system failure, corruption, or deletion.
What is the difference between full and incremental backup?
• Full backup: Copies all files every time.
• Incremental backup: Only copies files that have changed since the last backup — saves time and space.
What is compression software?
Software that reduces the size of files so they take up less storage and can be transferred more quickly.
What is the purpose of system cleanup tools?
To remove unnecessary files, manage startup programs, and improve system performance.
