Different types of computers with pictures

Consider this sentence: " computers are everywhere." Does it sound like an overstatement? A cliche? No matter how you perceive the impact of computers, the statement is true. Computers are everywhere. In fact, you can find them in some pretty unlikely places, including your family car, your home applications, and even your alarm clock!

             In the past two decades, computers have reshaped our lives at home, work, and school. The vast majority of businesses now use computerized equipment in some way, and most companies are networked both internally and externally. More than half of all homes in the United States have at least one computer, and most of them are connected to the internet.Workers who once had little use for technology now interact with computers almost every minute of the workday.

What is Computer?

                           In basic terms, a computer is an electronic device that processes data, converting it into information that is useful to people. Any computer-regardless of its type-is controlled by programmed instructions, which give the machine a purpose and tell it what to do.

Different types of compute 

                 Computers are classified in many different ways, But here are the most way of differentiating the computers. 1. Computers for Individual Users 2. Computers for Organizations

Computers for Individual Users 

                               Most computers are meant to be used by only one person at a time. Such computers are often shared by several people, but only one user can work with the machine at any moment. The six primary types of computers in this category are

  1. Desktop computers
  2. Workstation computers
  3. Notebook computers
  4. Tablet computers
  5. Handheld computers
  6. Smart phones

 Desktop computers

                       The most common type of personal computer is the desktop computer- a PC that is designed to sit on a desk or table. These are the systems you see all around you, in schools, homes, and offices.

Today's desktop computers are far more powerful than those of just a few years ago, and are used for an amazing array of tasks. Not only do these machines enables peoples to do their jobs with greater ease and efficiency, but they can be used to communicate, produce music, edit photographs and videos, play sophisticated games, and much more.

Workstation computers

                                A workstation is a specialized, single user computer that typically has more power and features than a standard desktop PC. These machines are popular among scientists, engineers, and animations who need a systems with grater than average speed and the power to perform sophisticated tasks.

Workstation computers

Notebook computers

                                 Notebook computers, as their name implies, approximate the shape of an 8.5-by-11-inch notebook and easily fit inside a briefcase. Because people frequently set these devices on their lap, they are also called laptop computers.

                               Notebook computers can operate on alternating current or special batteries. These amazing devices generally weight less than eight pounds, and some even weight less than three pounds.

    Tablet computers

                            The Tablet PC is the newest development in portable, full-featured computers. The tablet PCs offer all the functionality of a notebook PC, but they are lighter and can accept input from a special pen called a stylus or a digital pen, that is used to tap or write directly on the screen.

Handheld computers

                              Handheld personal computers are computing devices small enough to fit in your hand. A popular type of handheld computer is the personal digital assistant(PDA). A PDA is no larger than a small appointment book and is normally used for special applications, such as taking notes, displaying telephone numbers and address, and keeping track of dates or agendas.

Smart Phones

                      some cellular phones double as miniature PCs. Because these phones offer advanced features not typically found in cellular phones, they are sometimes called smart phones. Therefore features can include web and e-mail access, special software such as personal organizer, or special hardware such as digital cameras or music players.
