Basic Computer Terms December 19, 2007Posted by Chaim Gartenberg in : Computers, Tech Terms , trackback
To start out, we’re going to introduce some basic computer terms that we’ll be using frequently to describe things on the site. Just as a side note, most computer terms are acronyms:
OS-Operating System: An OS is the main software of the computer. The most common ones are Mac OS X (Tiger and Leopard) and Windows (XP and Vista)
CPU – Central Processing Unit: Effectively the brains of the computer. It is the main processor of the computer meaning that it controls the main functions of the computer.
RAM – Random Access Memory: A non-persistent (doesn’t stay when the computer shuts off) form of memory. Is where the programs are kept when they are open on a computer.
Hard Drive – The main persistent (information stays even when computer is turned off) memory of most computers. This is where everything, from files (music, videos, pictures, documents etc.) to programs (iTunes, AIM, Internet Explorer, Games etc.) are stored.
Hardware: Physical parts of the computer, such as the screen, keyboard, and mouse.
Software: Programs and digital parts of the computer.
Firmware: Software for the hardware, such as the software that allows the CPU to interact with the computer.
Flash Memory: Persistant solid-state memory like hard drives but with no moving parts). This is much more reliable then hard drvies, which have moving parts, but are currently much more expensive (Example: 16 GB (Flash) iPod Touch- $399, 160 GB (Hard Drive) iPod Classic- $350.
