What are the ADVANTAGES of using a command line interface?
Expert users can work much faster than on a GUI
Output from one program can be piped into another, allowing batch processing
It's intuitive and easy to use
Graphics can be used in order to reduce the need for translation into other languages
Which type of utility software is used to reduce the size of files?
Compression
Defragmentation
Antivirus
Backup
Anna has noticed that her HDD is running slowly. She runs defragmentation software on her OS and notices that the speed of her disk increases. Why?
The defrag software rearranges the files on her hard disk so that all of the parts of each file are next to each other. This means that the hard drive does not need to seek so much in order to locate the files
The defrag software deletes unused files, freeing up more space on the hard drive, which in turn allows more virtual memory to be allocated which speeds up the whole system
The defrag software compresses the files, freeing up more space on the hard drive, which in turn allows more virtual memory to be allocated which speeds up the whole system
The defrag software shouts really loudly at the hard disk, threatening to replace it with a newer model if it doesn't pull its finger out. "And I don't want to hear any talk of UNIONS either!" says the defrag software. The defrag software is a tyrant
What is the difference between an incremental backup and a full backup?
An incremental backup only saves changes to files since the last backup; a full backup saves everything
An full backup only saves changes to files since the last backup; an incremental backup saves everything
An incremental backup only happens once a week; a full backup happens every day
Incremental backups are stored on-site; full backups are stored in the cloud.
Which of the following memory and CPU management functions does the OS perform in order to allow the system to multitask
Each application is allocated a different memory space so that their data does not interfere with each other
The OS moves unused parts of memory to storage and swaps it out as necessary
The OS splits CPU cycles up between open applications
The OS Prioritises processes so that instructions are executed in an efficient order
