4 A complete working computer that has all of the necessary parts to make the computer function. HardwareSoftware Computer System

5 Hardware The physical components of the computer. The actual equipment you can see and touch.

6 Hardware Peripheral A peripheral is an external piece of hardware that is important, but not necessary for a computer system to work.

7 Hardware Input Devices Processing Output Devices Storage Devices

8 Input Devices Hardware that enables a computer user to enter data and programs into a computer.

9 Processing The main parts of a computer system that process information.

10 Processing The main parts of a computer system that process information. CPU Central Processing Unit The CPU is often called the brains of the computer.

11 Processing The main parts of a computer system that process information. CPU Central Processing Unit ROM Read Only Memory The CPU is often called the brains of the computer. ROM is permanent internal memory that cannot be changed.

12 Processing The main parts of a computer system that process information. CPU Central Processing Unit ROM Read Only Memory RAM Random Access Memory The CPU is often called the brains of the computer. ROM is permanent internal memory that cannot be changed. RAM is temporary memory that can be changed.

13 Output Devices Hardware that represents data as either hard copy or soft copy after is has been processed by the computer.

14 Output Devices Hardware that represents data as either hard copy or soft copy after is has been processed by the computer. Monitor Represents data as soft copy. Some common monitors are CRT or flat- panel.

23 Network Computers that are connected in order to share information and resources. The main computer on a network is called a file server. LAN – Local Area Network Computers are in close proximity to each other. WAN – Wide Area Network Computers are in a larger geographical area.

24 Software A set of instructions or programs that tell a computer what to do.

25 Software Operating System or Platform Applications or Programs

26 Operating System or Platform This type of software manages RAM, controls peripheral devices, manages file operations (saving, opening, deleting, renaming, etc.), monitors system performance, and provides a user interface

27 Operating System or Platform This type of software manages RAM, controls peripheral devices, manages file operations (saving, opening, deleting, renaming, etc.), monitors system performance, and provides a user interface DOS & Windows DOS is a command-line interface OS. It is not very user-friendly! Windows is a GUI OS environment that works with DOS. It uses icons and menus to make computers easy to use. You can multitask with Windows.
