Describe the different types of computers. What is the most common type? What are the types of microcomputers?
Supercomputers are the most powerful type of computer. These machines are special high-capacity computers used by very large organizations. Fujitsu’s K computer is one of the 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 and data storage. For example, insurance companies use mainframes to process information about millions of policyholders.
Minicomputers, also known as midrange computers, are refrigerator-sized machines. Medium-sized companies or departments of large companies typically use them for specific purposes. For example, production departments use minicomputers to monitor certain manufacturing processes and assembly-line operations.
Microcomputers are the least powerful, yet the most widely used and fastest-growing type of computer. There are six types of microcomputers: desktop, media center, notebook, tablet PC, netbook, and handheld computers. Desktop computers are small enough to fit on top of or alongside a desk yet are too big to carry around. Media centers blur the line between desktop computers and dedicated entertainment devices.
Notebook computers, also known as laptop computers, are portable, lightweight, and fit into most briefcases. There are two types of tablet PCs. The traditional tablet PC is effectively a notebook computer that accepts stylus input. The newer type of tablet PC is sometimes referred to as a slate computer. This computer’ s system unit is a thin slab that is almost all monitor. The best-known tablet PCs are Apple; s iPad, Motorola’ s Zoom, and Samsung; s Galaxy Tab. Netbooks are smaller, lighter, and less expensive than notebook computers. Handheld computers are the smallest and are designed to fit into the palm of one hand. These systems contain an entire computer system, including the electronic components, secondary storage, and input and output devices. Personal digital assistants and smartphones are the most widely used handheld computers. Smartphones are cell phones with wireless connections to the Internet. Their growth has been explosive in the past few years.
