Utilities Flashcards
(13 cards)
What is the primary function of utility system software?
Helps to maintain or configure a computer
Utility software includes built-in utilities with the operating system and additional software that can be installed.
What do defragmentation utilities do?
Reorganise data on the hard drive to put fragmented files back together
They also collect free space to prevent further fragmentation.
What happens to files on a hard disk over time?
They become fragmented, leading to slower read/write speeds
This occurs as files are moved, deleted, or change size, creating gaps on the disk.
How do SSDs differ from traditional hard drives regarding fragmentation?
Fragmentation doesn’t affect SSDs as they have no moving parts
In fact, defragmenting SSDs can shorten their lifespan.
What is a backup in computing?
A copy of a computer system’s files and settings stored externally
Backups are essential for data recovery in case of data loss.
What are the two main types of backups?
Full backups and incremental backups
Full backups copy every file; incremental backups copy only files created or edited since the last backup.
What is a full backup?
A backup that copies every file on the system
It uses a lot of storage space and takes longer to create but is faster to restore from.
What is an incremental backup?
A backup that copies only files created or edited since the last backup
It uses less storage space and is quicker to create.
What does compression software do?
Reduces the size of files to take up less disk space
Common formats include zip and rar; compressed files need extraction before use.
What is the purpose of encryption software?
To scramble data to prevent unauthorized access
Encrypted data can be decrypted using a special key.
True or False: Utilities are only limited to backup and defragmentation software.
False
Other utilities include compression software, encryption software, disk cleaners, anti-virus software, and more.
Fill in the blank: _______ software helps maintain a computer system.
[Utility]
Utility software includes various tools that perform specific maintenance tasks.
What is the benefit of having a backup regime?
Ensures data can be recovered in the event of data loss
Regular full and incremental backups help mitigate risks of losing important data.
