  • Operating systems are the software that tell your computer how to function—there are some hardware differences between macs and PCs, but the main difference is that they run different operating systems. Yosemite for macs and Windows 8 on PCs. An operating system is required for a computer to function, it wouldn’t know what to do if it didn’t have some type of OS installed.
  • GUI — graphical user interface. Means that you can interact with your computer in a visual way rather than just typing in commands. It makes using a computer more intuitive.
  • Icons are small images/symbols are are used to represent a file or application.
  • An application is a piece of software that is designed to do a certain task. For example, Safari is a web browser application that’s function is to allow you to browse the internet. Photoshop is an application that allows you to edit photos.
  • Files come in many different types and is a resource for storing information. Depending on the type of file they can be edited in various applications.
  • folders are a way of storing and organizing different files on your computer.

  • Virus is an unwanted program that causes destruction on your computer or corrupt your files.
  • Firewalls are software that are intended to protect your computer from viruses

  • The hard drive is the central storage place on your computer. It holds all the information stored on your computer — files, applications, the OS.
  • CPU — central processing unit. The brains of the computer where most processing takes place.
  • Motherboard— circuit board that connects the main components together and allows them to communicate.
  • Graphics card — converts code into a visual format for you to more easily use your computer
  • RAM — Random access memory — the conscious memory of your computer. Whatever it is doing right now uses the RAM. It accesses things from the hard drive.
  • ROM — Read only memory — stores important information your computer needs to use to function, like how to open and run applications, or turn on.
  • USB port — universal serial bus. most common type of connection, many common peripherals connect using this type of connection.
  • heat sync — aka fan. Used to keep your computer hardware cool
  • Power supply — converter box that converts the electricity from AC power to DC power that your computer can use.
  • Peripherals — unnecessary, though useful additions to a computer— not needed to turn on and work, but helpful in many ways. There are input peripherals, like mouses, keyboards, microphones— things that put data into your computer. Output peripherals give you information from your computer, for example a speaker, or the monitor.
  • hertz — unit of measurement to measure frequency of cycles. On a computer the cycles indicate how fast something goes.
  • Storage — smallest unit is a byte, then when you have 1024 of those you get a kilobyte, 1024 of those gives you a megabyte etc. They are in order:
    • byte, kilobyte, megabyte, gigabyte, terabyte, petrabyte
