The processor is very small so that called microprocessor and device called Microcomputers. They became popular for control related functions as opposed to computing prowess. Hot swap disk drive bay in a server system, By Mixabest (Own work) [Public domain], via Wikimedia Commons. Streaming players like Google Chromecast and Roku. They went from using a cathode ray tube to a liquid crystal display. Hollywood uses supercomputers to create realistic animations. Meteorologists use them to simulate weather behavior. They include a combination of the outer hardware, microprocessor chip, and software. The term is still used for the large computers of today. The super computer is used for specialised applications such as large-scale numerical problems in scientific and engineering disciplines. Personal digital assistants (PDAs), also called handheld computers, pocket PCs, or palm top computers, are battery-powered devices that are small enough to carry almost anywhere. Supercomputers can go even faster with the rate of petaFLOPS (or PFLOPS). Although it is a standalone system, usually it forms part of a network and it uses Unix or Windows NT as operating system. They have a small memory, less processing power, are physically smaller, and permit fewer peripherals compared to super and mainframe computers. These are computer-based systems which are standalone electronic hardware designed to perform dedicated computing tasks. The latter can now perform most of the tasks reserved for minis. In terms of features, smartphones support full email capabilities as well as multiple functions to serve as a complete personal organizer. This group includes personal digital assistant, pen-based computer, hand-held computer, notebook computer and laptop computer. A microcomputer is a single user device. Desktop computers, laptops, gaming consoles, sound and navigation system of a car, personal digital assistant (PDA), tablets and smartphones are all types of microcomputers. Time-sharing, to allow multiple users to interact concurrently on a single system. Popular devices that may be categorized under embedded systems are listed below: This article is accurate and true to the best of the author’s knowledge. • Desktop Computer: a personal or micro-mini computer sufficient to fit on a desk. These computers are the largest in terms of size. Some have more advanced capabilities, such as making telephone calls or accessing the Internet. Minicomputers are general purpose devices without the monumental expenses associated with a larger system. Smartphones today, however, have evolved into general purpose mobile computers. Particular features that make mobile systems a favorite include: The most common types of mobile computers include: A 17 inch laptop and 10 inch netbook side by side. Micro Computer Performance is measured in terms of speed of processing instructions, storage capability to handle a large number of input and output devices, and nature of operations performed. Computers are classified into six major categories according to size, with each excelling at specific functions. A computer can be classified into 3 major categories on the basis of: Size and Capability; Function; Architecture; Tasks Performed* Classification of computers by Size and Capability. Computer on the basis of Size can be classified into 4 major types: Microcomputer; Minicomputer; Mainframe computer; Supercomputer Firmware on these systems is written in the read-only memory (ROM) or flash memory chips. Of course bigger and more multitasking installations will require multiple system and storage installation. Local Area Network (LAN)2. Its CPU is a microprocessor. Also known as big iron, these systems can handle massive amounts of data going in and out simultaneously. » Mainframe Computer Laptops are lightweight mobile PCs with a thin screen. Examples of these devices include smartwatches, smartglasses, smartclothes, smartshoes. They handle exhaustive scientific applications that require complex and real-time processing. The types of computer are: Super Computer, Mainframe Computer, Mini Computer and … They have evolved from the grid to cluster systems of massively parallel computing. They soon became the choice for complex projects. Just like any other desktop, they attach to peripheral accessories via USB ports and the monitor via VGA or DVI ports. They usually have longer lasting batteries (5 hours minimum) and have strong hardware and processing power to run any software around. Depending on the manufacturer, other functions might include additional interfaces such as miniature QWERTY keyboards, touch screens, built-in cameras, contact management, built-in navigation software, ability to read office documents in PDF and Word file formats, media software for playing music, browsing photos, and viewing video clips.
