They are the most costly and quickest computers available. Computing professionals use them for tasks requiring the processing of enormous volumes of data. Applications Supercomputers are used for tasks such as census count, forecasting the weather, designing aircraft, modeling molecules, and breaking encryption codes. Mainframe Computers Mainframes are water- or air-cooled computers that differ in size from small, to medium, to large, depending on their use. Applications Mainframes process billions of instructions per second. They are used by large organizations—such as banks, airlines, insurance companies, and colleges—for processing millions of transactions. Small Mainframes Small mainframes, also called midsize computers, used to be called minicomputers. The only type of computing machine available until the late 1960s Workstations Workstations are costly, powerful personal computers usually used for complex scientific, mathematical, and engineering calculations and computer-aided design and computer-aided manufacturing. Applications Graphics Capabilities Workstations are used Workstations have for such tasks as caught the public's designing airplane eye mainly for their fuselages, developing graphics capabilities, prescription drugs, which breathe three- and creating movie dimensional life into special effects. movies. Introduced in the early 1980s Microcomputers Microcomputers, also called personal computers (PCs), can fit next to a desk or on a desktop or be carried around. They either are stand-alone machines or are linked to a computer network, e.g., a local area network. Several Types of Microcomputers Desktop PCs Notebook Computers Desktop PCs are older microcomputers Notebook computers, also called laptop whose case or main housing sits on a desk, computers, are lightweight, portable with a keyboard in front and monitor computers with a built-in monitor, keyboard, (screen) often on top. hard-disk drive, CD/DVD drive, battery, and AC adapter plugged into an electrical outlet. Several Types of Microcomputers Netbooks Tablet Netbooks are low-cost, lightweight, A tablet is a mobile gadget, typically with a computers with tiny dimensions and mobile operating system, a rechargeable functions designed for basic tasks, such as battery in a single thin package, and a web searching, email, and word touchscreen display processing circuitry. processing. Several Types of Microcomputers Smartphones Smartphones are mobile phones with highly advanced features—a high- resolution touchscreen display, Wi-Fi connectivity, among others. Microcontrollers Microcontrollers, also called embedded computers, are the minute, specialized microprocessors installed in “smart” appliances and automobiles. These microcontrollers enable microwave ovens, for example, to store data about how long to cook your potatoes and at what power setting. Microcontrollers Microwave Ovens Digital Cameras Microcontrollers enable microwave Microcontrollers are ovens, for example, to store data about behind single-function how long to cook your potatoes and at products such as digital what power setting. cameras, MP3, and MP4 players. Medical Devices Blood-pressure monitors, airbag sensors, gas and chemical sensors for water and air, and vibrations sensors use microcontrollers. Other IT Infrastructures or Gadgets Network Servers A network server is a central computer that stores the collections of data (databases) and programs for connecting or supplying services to PCs, workstations, and other devices, which are called clients. A wired or wireless network links these clients. The entire system is called a client/server network. Small Organizations Large Organizations In small organizations, In large organizations, servers servers can store files, may also house enormous provide printing stations, libraries of financial, sales, and and transmit emails. product information. Computer Peripherals A computer peripheral is any detachable device that provides input and output for the computer machine. Computer peripherals, or peripheral devices, are often called “I/O devices” because they supply input and output. Hard Disk Drives A hard disk drive, also abbreviated to HDD, is an electronic data memory device that uses magnetic storage to keep and retrieve digital information using one or more rigid, rapidly rotating disks coated with magnetic material. Solid-State Drives A solid-state drive (SSD) is a solid-state storage device that uses integrated circuit assemblies as memory to store data persistently, typically using flash memory.
