Supercomputers – a powerful computer that can process large amounts of data and do a great amount of computation very quickly. Supercomputers are used for areas related to:
Supercomputers are useful for applications involving very large databases or that require a great amount of computation. Supercomputers are used for complex tasks, such as:
Mainframe computers– a high-performance computer used for large information processing jobs. Mainframe computers are primarily used in :
Mainframe computers are useful for tasks related to:
Minicomputers– a mid-range computer that is intermediate in size, power, speed, storage capacity, etc., between a mainframe and a microcomputer. Minicomputers are used by small organizations. “Minicomputer” is a term that is no longer used much. In recent years, minicomputers are often referred to as small or midsize servers (a is a central computer that provides information to other computers). Personal computers(PC) – a small computer designed for use by a single user at a time. A PC or microcomputer uses a single chip (microprocessor) for its central processing unit (CPU). “Microcomputer” is now primarily used to mean a PC, but it can refer to any kind of small computer, such as a desktop computer, laptop computer, tablet, smartphone, or wearable. Types of personal computers– a personal computer that is designed to stay at one location and fits on or under a desk. It typically has a monitor, keyboard, mouse, and a tower (system unit). – A portable personal computer that is small enough to rest on the user’s lap and can be powered by a battery. It includes a flip down screen and a keyboard with a touchpad. – A wireless touchscreen PC that is slightly smaller and weighs less than the average laptop. – A mobile phone that performs many of the functions of a personal computer. A notebook computer is a battery- or AC-powered personal computer generally smaller than a briefcase that can easily be transported and conveniently used in temporary spaces such as on airplanes, in libraries, temporary offices, and at meetings. A notebook computer, sometimes called a laptop computer, typically weighs less than 5 pounds and is 3 inches or less in thickness. Among the best-known makers of notebook and laptop computers are IBM, Apple, Compaq, Dell, Toshiba, and Hewlett-Packard. Notebook computers generally cost more than desktop computers with the same capabilities because they are more difficult to design and manufacture. A notebook can effectively be turned into a desktop computer with a docking station, a hardware frame that supplies connections for peripheral input/output devices such as a printer or larger monitor. The less capable port replicator allows you to connect a notebook to a number of peripherals through a single plug. Notebooks usually come with displays that use thin-screen technology. The thin film transistor or active matrix screen is brighter and views better at different angles than the STN or dual-scan screen. Notebooks use several different approaches for integrating a mouse into the keyboard, including the touch pad, the trackball, and the pointing stick. A serial port also allows a regular mouse to be attached. The PC Card is insertable hardware for adding a modem or network interface card to a notebook. CD-ROM and digital versatile disc drives may be built-in or attachable. This was last updated in June 2007 Continue Reading About notebook computer

Which device is used in portable computers such as laptops and notebooks as a replacement of mouse?Touchpads are a common feature of laptop computers as opposed to using a mouse on a desktop, and are also used as a substitute for a mouse where desk space is scarce.
What is a netbook laptop?A netbook is a type of laptop that is slimmer, lighter, and offers a more simplified set of tools. It's often referred to as a “notebook,” but many people call it a “laptop” as well. In fact, many netbooks actually have the term “laptop” in their name.
