In what ways has computer technology changed in your own lifetime?

The first time i used a computer in school i was 6 years old , and they were really slow and also the monitors were very thick , now the computers i have seen and also have worked with have the monitors very thin. Another thing that has changed is that the computers are actually much faster then when i used the first computers in my first grade class. Also when i would have to trasfer something to my teacher i would either have to send him an e-mail just like now but it would take like , 2 to 3 hours to upload the attachment into the e-mail and also now we use USB's to transfer our files from our own computer to another one but before we had a USB everyone would use floppys and the bad thing about that was that it would not store that much information as a USB and it would also take very long to upload aswell. Well my gradma told me that before she knew anything about a computer she would have to work very hard to find her answers now hse says that i have it easy that i don't have to do much work to find answer to my answers just "google" it . My gradma also says that she likes it to because she also uses it for "googling" things aswell

Byte

Byte - A byte is a unit in computer science it is an ordered collection of bits usually a byte was the number of bits usually 6, 7, 8, or 9 used to encode a character of text in a computer

Bit

What are the parts of a computer?

A couple parts of the computer is the hard drive , the power supply , the CD - ROM , the motherboard , and also the graphics card. Also the memory .

Name 5 Types Of Computers :
One type of Computer and one of the most common computers are the desktop the desktop is intended to just be placed in one place and never to be moved it is usually used in schools , homes , and offices.

Another type of a computer is the laptop the laptop is intended to be used outside becuase it doesn't use the ethernet cable , unless you connect one to it becuase it runs wi-fi.

The third type of computer is ­the Personal Digital Assistants also known as PDA'S are computers that use flash memory instead of a hard drive for storing information. PDAs are usually smaller than a book also are very lightweight with a very good battery.

The fourth type of computer is the Server a computer that has been used to provide services usually internet to other computers over a network. Servers usually have powerful processors and a lot of memory and very large hard drives.

The last type of computer is the SuperComputer this type of computer usually costs hundreds of thousands or even millions of dollars. Most supercomputers are single computer systems, a lot of the super computers are made up of many high performance computers working together as a single computer system. The best known supercomputers are built by a company called Cray Supercomputers.

What Is A Computer?

A computer for me is an object that processes information and saves information and also something with a CPU (Cental Processing Unit)
