Introduction to Computers Instructor: Brad Atkinson
Have you ever felt like this? How about this?
A computer is an electronic device that has the ability to store, retrieve, and process data, and can be programmed with instructions that it remembers. The physical parts that make up a computer are called hardware. Programs that tell a computer what to do are called software.
Areas of Discussion Hardware Software
The physical components which make up a computer system. The keyboard, mouse, CPU, memory, storage devices, printer, and monitor are a few of these components.
Terms CD-ROM – Stores information/instructions on disk in a read only format. Floppy Disk – Made of thin, Mylar plastic that is used to store information. Hard Drive – A disk drive that reads from and writes to a hard disk. The Hard Drive stores large amounts of information magnetically, also known as the C drive. Peripheral – Hardware device connected to the computer. Ethernet Card – A network adapter that enables a computer to connect to a network. Modem – An electronic device for converting between serial data from a computer and an audio signal suitable for transmission over telephone lines.
Terms Monitor – Also called a display, or screen, where information is displayed in pixels. CPU (Central Processing Unit) – Processes data and instructions, performing calculations on the data. Also called the Processor. Memory – Temporary storage space on a chip inside the computer used to hold programs and data temporarily while being accessed. RAM (Random Access Memory) – The amount of RAM determines the number of computer programs which you can run at once and how fast the programs will be processed.

Instructions which ‘tell’ the computer how to process information. There are two types of software; Operating System and Application Software. Windows is an examples of an Operating System. Application software are programs which fall under some of the following categories: utility, educational, data management, multimedia, productivity.
Terms Icon – Picture displayed on the screen which represents a program, file, or folder, which is accessed by double-clicking with the mouse. File – A file is a collection of data, or information, stored on your computer or disk. Folder – A folder is a place where you can organize files or documents. A folder is also known as a directory.
Size & Speed Info These sizes refer to the size of memory, hard drive space, and files on your computer. Kilobyte (KB) – 1 thousand bytes. Megabyte (MB) – 1 million bytes. Gigabyte (GB) – 1 billion bytes. These sizes refer to the processor speed of a computer. Megahertz (MHz) – Millions of cycles per second. Gigahertz (GHz) – Billions of cycles per second.
