Jeremy's Operating System Mind Map

Jeremy's Operating System Mind Map

1. Device Drivers (Specific software used to interact with hardware.)

   • Each OS has it own unique drivers.
   • Allows the OS to communicate with a device.
   • Without device specific drivers, hardware may not perform as expected.

2. Kernel (Data management)

   • Running programs efficiently.
   • Controls storage to and from secondary storage devices. (I.e. USB stick)
   • Controls memory use by other software.

3. User Interface (Most commonly a GUI.)

   • Reads mouse clicks and keyboard input.
   • Images called icons representing different programs.
   • The other common interface is purely text based.

4. System Utilities (Management of background services with no user input.)

   • Cryptographic encoding of passwords.
   • Print Spooler (Used mainly in Windows OS.)
   • File Management. (keeping files stored on the computer in organized folders.)

5. Security

   • Built in firewall (Protection against viruses.)
     • Often used in addition to free virus protection software such as AntiVir and AVG.
   • Password to restrict access to the owner only.
     • Multiple user accounts can be used each with their own password.
   • Virus scanning utilities.
     • 3rd party software often is needed to protect against a wider variety of threats.

6. Assumptions

   • Viewer knows basic computer jargon.
   • Viewer knows basics of at least one operating system.
   • Viewer has used at least one of the big 3 operating systems. (Windows, Mac OSX, Linux)
