Technology 5 Programs

Programming All of the information that travels through your computer is stored on bits as either an on or off signal. Using bits and bytes in different combinations to represent a code is known as programming. These codes allow the computer to understand instructions. Computer programmers are people who write these codes to create programs.

There are even programming languages that make it easier, so that these people don't have to remember all the bit or byte combinations. Programming allows people and computers to communicate more easily.

Computer Programs A program is a set of instructions that tells the computer how to perform a specific task. In order for your computer to know how to run a program, you must first  install the program from the game software - usually a CD. Installing the program means that you are copying the program or instructions that are stored on the CD on to your computer's hard drive. Many programs (especially games) are very large and would take up lots of memory space on your hard drive. To keep that from happening, these programs are designed to only copy part of the program onto your computer. The rest of the program stays on the software disk. The program cannot be run from your computer unless you have the disk in the disk drive so that RAM can read the rest of the program from it.

Types of Programs There are many different types of programs which are grouped according to the tasks that they perform. Word processing - letter writing, essays, writing stories Database - address books, mailing lists Spreadsheets - storing financial information Research - encyclopedias, informational programs Entertainment - games, music/video programs Education - skill practice games, tutorials, how-to programs Desktop Publishing - creating birthday cards, newsletters, etc.

Programs do much of the work for us, when we perform tasks on the computer. The program instructs the computer in a language that it understands. Programs are like translators that allow people to work with computers without learning the computer's language.
