This means that they work with electricity. Application software gives the computer instructions for doing specific tasks, such as word processing or playing games.

The operating system controls how the different parts of hardware work together. They send data through the air using a small antenna.Ĭomputer software is divided into two basic types-the operating system and application software. Some computers use wireless communication devices. Modems are communication devices that can send data through telephone wires or television cables.

They let people send data from one computer to another and connect to the Internet. Output devices include the monitor (or screen), printer, and speakers.Ĭommunication, or network, devices connect computers to each other. Output devices let the user see or hear the results produced by the computer. Input devices include the keyboard and the mouse. Input devices let the user enter data or commands into the computer. Input and output devices are other types of hardware. Some storage devices put data on disks that can be easily moved from one computer to another. The hard drive stores data on a metal disk inside the computer. Most computers have a storage device called a hard drive. The programs and data are kept permanently on hardware called storage devices. The memory is hardware that holds programs and data while the microprocessor uses it. The microprocessor handles all the information that goes into and comes out of the computer. The microprocessor is the computer’s “brain.” It is also called the CPU, or central processing unit. Software is the programs, or instructions, that tell the hardware what to do.Īll computers have the same basic hardware. Hardware is the computer’s physical parts. A computer system requires both hardware and software.
