TYPES OF COMPUTER

• Personal computer also known as PCs are the least powerful, yet the most widely used and fastest-growing type of computer.There are five types of personal computer: Desktops, Laptops, Tablets, Smartphones, and Wearable.
• Desktop computers are small enough to fit on the top of or alongside of a desk yet are too big to carry around.

• Laptop computers, also known as notebook computers, are portable and lightweight and fit into most briefcases.
  
                                                        LAPTOP.
• Tablets, also known as tablets computer, are smaller, lighter, and generally less powerful than laptops. Like a laptop, tablets have a flat screen but typically do not have a standard keyboard.

• Supercomputers are the most powerful type of computer. These machines are special, high-capacity computers used by very large organizations. Supercomputers are typically used to process massive amounts of data. For example, they are used to analyze and predict worldwide weather patterns. IBM's Blue Gene and CDAC's PARAM are two of tow fastest computers in the world.

• Mainframe computers occupy specially wired, air-conditioned rooms. Although not nearly as powerful as supercomputers, mainframe computers are capable of great processing speeds. For example, insurance companies use mainframes to process information about millions of policyholder.

• Midrange computers, also referred to as servers, are computers with processing capabilities less powerful than a mainframe computers yet more powerful than a personal computer. Originally used by medium-size companies or departments of large companies to support their processing needs, today midrange computers are most widely used to support or serve end users for such specific needs as retrieving data from a database or supplying to application software.
