The Operating System
• without an operating system:• the screen would be blank• there'd be no response when you tap the
keys• disk programmes wouldn't load• the printer wouldn't print
• In fact, nothing would work

Performs basic tasks
• recognises input from the keyboard
• sends output to the display screen
• keeps track of files and directories
• controls peripheral devices

Disk Operating SystemTwo Types1) Command Interpreter 2) GUI (Graphical User Interface)
![Page 12: The Operating System. without an operating system: the screen would be blank there'd be no response when you tap the keys disk programmes wouldn't load](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649e225503460f94b0f59b/html5/thumbnails/12.jpg)
1) Command Interpreter
• Difficult to use.• Commands have to
be typed, Eg copy a:*.*
• Syntax is extremely important.
• Being replaced by GUI operating systems.

2) GUI• No need to learn
complex commands
• Easy to move data from one place to another
• Visually interesting
• Getting better and better with each new generation
