Search engine

A Search engine is a web side on the www of the Internet that helps us to quickly and easily find the web pages we want.
When you type words into the search engine, it looks for web pages with the words that you typed. There could be thousands, or even millions, of web pages with the words you typed! So, the search engine helps you by putting the web pages it thinks you want first.
Search engines are very useful if you want to find almost anything quickly and easily.
Some examples of search engines are:
Google (has the largest number of users in the United States)
Yahoo!
Forestle (helps the environment)
Ask.com
Bing
Some examples of business search engines are:
Masterseek
BusinessGlobe
Some examples of multi-search engines are:
Dogpile
CooBi.netne.net

Tertiay storage

Large tape library. Tape cartridges placed on shelves in the front, robotic arm moving in the back. Visible height of the library is about 180 cm.
Tertiary storage or tertiary memory,[3] provides a third level of storage. Typically it involves a robotic mechanism which will mount (insert) and dismount removable mass storage media into a storage device according to the system's demands; this data is often copied to secondary storage before use. It is primarily used for archival of rarely accessed information since it is much slower than secondary storage (e.g. 5–60 seconds vs. 1-10 milliseconds). This is primarily useful for extraordinarily large data stores, accessed without human operators. Typical examples include tape libraries and optical jukeboxes.
When a computer needs to read information from the tertiary storage, it will first consult a catalog database to determine which tape or disc contains the information. Next, the computer will instruct a robotic arm to fetch the medium and place it in a drive. When the computer has finished reading the information, the robotic arm will return the medium to its place in the library

Central processing unit and software compatibility

The computer processor inside a PC or PC-clone computer has totally different architecture (microscopic "wiring" schematic) inside the central processing unit chip (the CPU, or "chip"). In other words, the specific way the circuits are laid out in a computer chip (CPU, central processing unit) is called the chip architecture. PC chips and Mac chips have processing units with totally different architecture. Software is not interchangeable. Buy Mac software for the Macintosh and buy PC software for PC computers. An Apple or Mac computer is not a PC. Most PC Computers are sold new with a Windows operating system but keep in mind that other operating systems can also run on PC-architecture machines. One example of another operating system that can run on a PC machine is Linux for Windows. When two operating systems are on a disk they are installed on separate "partitions" of the disk. That is similar to two songs on one CD having to be on separate "tracks".

Buying a computer

It is best to ask and to compare features before you buy a computer. The first question to ask yourself is, "What do I want a computer to do?" Do you need it only for e-mail and a little light letter writing or do you need it for graphics and Web page authoring? Will you also want extra storage for your music files or graphics files? Do you need any hardware for game playing? What type of Internet connection will you have: dialup, cable, DSL, or other broadband connection? Will you be needing a computer for school work? Accounting? Make a list of what you need the computer to do before you talk to anyone about purchasing a computer. Your needs will be different that those of the next person.

A basic computer system

A computer system refers to the computer AND all of its equipment. Equipment like speakers, printer, keyboard, scanner, etc. is called peripheral equipment, sometimes shortened to "peripherals". The central processing unit (CPU) is considered to be "the computer". Without peripheral equipment (such as monitor, printer, speakers, etc.) for input and output the microcomputer (home computer) will not be able to do anything you find useful. Your computer system cannot help you type a letter unless you have some type of software (program) to do this. Most typing is handled by a "word processing" program. A software program for your computer can be purchased at stores like Office Depot, Staples, and computer stores. Check your local telephone directory for a computer store in your area. Sometimes when you purchase a computer it already has a word processing program installed. If you buy a computer from a large electronics chain store, even if you have to travel out of town, you will get a better price as a rule than buying from a smaller chain store in town. Ask in town first, if they would be willing to match another store's Advertised price... See "Buying A Computer", next.
