1. Operating system

   • Linux

     • OS (Apple)
   • Why do we need an operating system?
     • It allows programs to run on different types of hardware
     • Allows a user interface
     • It translates code and makes the hardware do what its meant to do

2. BIOS (Basic input/output system)

   • It allows you to set up the boot order. This is useful because if you need something on a memory stick so that a new operating system is installed it allows you to load it first
   • It allows you to set up a password on your BIOS so no-one can mess up your computers settings and you can keep it the way you like
   • It allows you to change the amount of memory you commit to the graphics. This is useful because if you use your computer for gaming you can change how good the graphics are.

3. Components

   • ROM
     • This is needed because it has all the start up data and without it your computer wouldn't start up
   • Hard drive and memory
     • The hard drive is used to store all the data like your operating system.
     • Memory is used to store actively running programs and is smaller than the hard drive
   • Cables used to connect Hard drives and optical drives to the Motherboard
     • Parallel ATA
       • its controllers are on each drive, meaning the drive can connect directly to the motherboard
     • Power cables
       • They are used because they give power to the drive allowing to do what its meant to do

4. Utility software

   • Optimised performance and security
   • Antivirus
     • Antivirus is
   • Automatic updates
   • Firewall
   • Disk defragmenter
   • Disk cleanup
