Introduction to Computers

A computer is an electronic device that manipulates information or "data." It has the ability to store, retrieve, and process data.
All types of computers consist of two basic parts – hardware and software.

• Hardware is any part of your computer that has a physical structure, such as the computer monitor or keyboard.
• Software is any set of instructions that tells the hardware what to do. It is what guides the hardware and tells it how to accomplish each task.
