What is meant by a ‘peripheral’?
A computer peripheral is any external device that provides input and output for the computer. For example, a keyboard and mouse are input peripherals, while a monitor and printer are output peripherals.
What is meant by a driver; why do computers need them?
A driver provides a software interface to hardware devices, enabling operating systems and other computer programs to access hardware functions without needing to know precise details about the hardware being used.
Most operating systems include a file encryption utility. Why might a user want the documents on their computer encrypted?
Encrypting a document, such as a spreadsheet, for security purposes because of sensitive data.
Describe three advantages of using a command-line interface (CLI) over a graphical user interface (GUI).
• If you know the commands, a CLI can be a lot faster and efficient than any other type of interface. It can also handle repetitive tasks easily. • A CLI requires less memory to use in comparison to other interfaces. It also does not use as much CPU processing time as other interfaces. • A CLI doesn’t require Windows and a low-resolution monitor can be used. Meaning, it needs fewer resources, yet is highly precise.
What is the function of Memory management?
In operating systems, memory management is the function responsible for managing the computer’s primary memory.
What is the function of Processor management?
The OS decides which process gets the processor when and for how much time.
What is the function of Peripheral management?
Peripheral management is where the operating system controls how the peripherals function using drivers.
What does a full backup mean?
This makes a copy of everything on the system, even if it has not changed since the last backup.
What does an incremental backup mean?
This makes a copy of only the new files or any files that have changed since the last full backup and is much quicker to make than a full backup.
