Types of Computers There are different types of computer of varying size 
and power, including the following:Supercomputer (the most powerful type of 
mainframe); Mainframe (large, very powerful, multi-user i.e. can be used by 
many people at the same time, multi-tasking i.e. can run many programs and 
process different sets of data at the same time); Minicomputer (smaller than a 
mainframe, powerful, multi-user, multi-tasking); Personal computer (PC) 
(single user); Desktop computer (suitable size for sitting on an office desk);

Portable (can be carried around, can operate with batteries); Laptop (large 
portable, can be rested on user's lap); Notebook (size of a sheet of notebook 
paper); Handheld (can be held in one hand) Pen-based (main input device is an 
electronic pen); PDA (personal digital assistant, has functions such as task lists, 
diary, address book).
Processor. 
The processor e.g. Pentium, is the most important part of the computer. It 
processes the data and controls the computer. Powerful computers used as 
servers often have more than one processor. There are two main types of 
memory: a RAM (random access memory) holds the 
program instructions and the data that is being used by the processor, b ROM 
(read only memory) holds the program instructions and settings required to start 
up the computer.
Twitter 
Twitter is an online service that allows you to share updates with other 
users by answering one simple question: "What are you doing?" In order to use 
Twitter, you must first sign up for a free account. Once you have created your 
account, you can post your own updates and view the updates others have 
posted. You can search for people to follow or you can let Twitter select 
random users. Once you have selected a number of users, their most recent 
posts, or "tweets," will show up on your Twitter home page. Likewise, your 
own latest tweets will show up on the home pages of people who have decided 
to follow you.
