Its Very Hard To Imagine A World Without Computers



It's Very Hard To Imagine a​ World Without Computers!
It's very hard to​ imagine a​ world without computers! Everywhere you look computers are at​ work attempting to​ provide one service or​ another and make our lives easier .​
Computers,​ in​ one form or​ another can be found in​ vehicles,​ from cars,​ trucks and motorcycles to​ larger scale methods of​ transportation such as​ airplanes and trains .​
They are in​ your television set,​ your VCR,​ your toaster oven,​ etc .​
But when we​ conjure up the​ image of​ a​ computer usually our first thought is​ of​ a​ PC,​ otherwise known as​ a​ personal computer.
Personal computers can be purchased either as​ desktops or​ laptops and have so many different uses .​
Most of​ us would be lost without one at​ home or​ work or​ both! Many public libraries provide computers for the​ use of​ patrons,​ as​ it​ is​ a​ service that is​ invaluable to​ every one of​ us .​
E-mail or​ electronic mail is​ the​ quickest way to​ communicate with one another.
With one click on​ the​ send button a​ message is​ sent through cyberspace and arrives at​ the​ recipient's in​ box in​ a​ matter of​ seconds .​
Students of​ all ages reap the​ benefits of​ the​ Internet when it​ comes time to​ look up information for school papers.
And very few people would disagree that typing papers and reports on​ a​ computer is​ far superior to​ typing on​ those old rickety typewriters of​ yester years! And computers carry the​ added advantage of​ being able to​ save work for future use,​ which cuts down on​ a​ lot of​ headaches.
Computers process information and in​ some ways are very complex while in​ other ways are very simple to​ understand .​
To describe how they do this in​ brief,​ as​ a​ person types a​ series of​ words into the​ computer by way of​ the​ keyboard and with help from the​ mouse,​ they are able to​ view what they're typing on​ the​ computer monitor (or computer screen) in​ front of​ them.
What could be simpler? In the​ meantime the​ inside of​ the​ computer is​ very busy going through the​ information that is​ being entered into it​ and organizing it​ in​ a​ fashion that will be understandable to​ the​ computer user .​
The individual busy typing away has the​ opportunity to​ save the​ work they are doing in​ two ways,​ by way of​ saving it​ to​ the​ hard disk or​ drive or​ by saving it​ to​ a​ floppy disk or​ CD .​
Some people choose to​ do both,​ which is​ often wise to​ do.
All computers are made with certain pieces of​ machinery that enable it​ to​ do its job .​
Describing it​ in​ a​ general way,​ every computer comes complete with its brain,​ or​ central processing unit (CPU),​ the​ memory bank (which is​ self explanatory,​ think of​ your own memory),​ the​ main circuit board (often referred to​ as​ a​ motherboard),​ the​ power supply which takes care of​ all electrical functions,​ the​ hard drive which is​ the​ permanent storage unit of​ the​ computer,​ the​ standard software (otherwise known as​ the​ operating system),​ the​ IDE (integrated drive electronics controller),​ the​ PCI (or peripheral component interconnect bus),​ the​ SCSI,​ pronounced oddly enough as​ skuzzy which is​ the​ small computer system from which scanners or​ printers can be plugged into,​ and the​ graphic card and sound card which takes care of​ visual information and aural data respectively .​
In order to​ utilize a​ graphics card one needs an​ AGP (or accelerated graphics port) in​ the​ computer.
