What is the primary function of a utility program?

• To run application software for productivity.

• To manage the core functions of the operating system.

• To provide additional functionality and assist with system housekeeping or security.

• To develop new software applications.

Which of the following best describes how anti-virus software works?

• It encrypts all incoming files before they are opened.

• It compares parts of new or copied files with known virus definitions.

• It deletes all temporary files on the computer.

• It reorganises fragmented files on the hard drive.

A computer is experiencing slow file access, and its read/write access light is flashing frequently. Which utility program is most likely to resolve this issue on a hard disk drive?

• Compression software

• Encryption software

• Disk clean-up tool

• Defragmentation software

How does a disk defragmenter improve the performance of a traditional magnetic hard disk?

• It creates more free space by deleting duplicate files.

• It reorganises file fragments to be stored contiguously, reducing read head movement.

• It increases the rotation speed of the disk platters.

• It encrypts files to make them faster to access.

Which statement accurately explains why defragmentation is generally not recommended for Solid State Drives (SSDs)?

• a) SSDs do not use file fragments, so defragmenting would slow them down.

• b) Defragmenting an SSD offers no performance benefit and can shorten its lifespan.

• c) SSDs automatically defragment themselves.

• d) Defragmentation software is incompatible with SSD technology.

What is the primary benefit of using file compression software?

• It enhances the security of the file by adding a password.

• It reduces the storage space required for the file.

• It makes the file compatible with different operating systems.

• It allows the file to be streamed faster over a network.

When referring to an "encrypted hard drive," what does this mean?

• The hard drive is physically locked in a secure cabinet.

• The data on the drive has been encoded, making it unreadable without a decryption key.

• The drive has been scanned for malware and found to be secure.

• The drive's contents have been backed up to a cloud server.

A solicitor needs to send confidential court case information to a client. Why should they encrypt the files before sending them?

• To make the files load more quickly for the client.

• To reduce the file size for easier transmission.

• To ensure that only the intended recipient, with the correct key, can read the data.

• To prevent the files from becoming fragmented during transmission.

What is an "external hazard" that firewall software is specifically designed to protect computers from?

• Physical theft of the computer.

• Attacks from malicious IP addresses, such as Denial of Service attacks.

• Accidental deletion of system files by a user.

• Out-of-date anti-malware definitions.

How does a firewall provide security when a computer is connected to the internet?

• It physically blocks network cables from being disconnected.

• It encrypts all data passing through the network interface.

• It filters incoming and outgoing network packets based on rules, blocking unauthorised access.

• It automatically creates backup copies of all internet traffic.
