There are three major types of computer classifications: size, functionality and data handling. Classification of computers in relation to size divides computers into four main categories: mainframe computers, minicomputers, micro-computers and supercomputers. Different-sized computers offer different services. A computer can be as big as an entire room or as small as a microcontroller found in mobiles and embedded systems.Continue Reading
The microcomputers, sometimes referred to as the personal computers, are the most common types of computers used by people. They include in-car built computers, game consoles and desktop computers. Additionally, under the category of microcomputers, there are smaller computers, including laptops, mobile phones, tablets, programmable calculators, handheld game consoles, notebooks, smartphones and smart books.
Minicomputers, also known as mid-range computers, refer to a group of multi-user computers which are always in the middle range of systems on computing spectrum. Mainframe computers comprise of large institutional computers meant to serve multiple users who are working from smaller single machines. Thus, mainframe computers are typically found in institutions such as banks, big business buildings and government offices. Finally, the classification of supercomputer represents all large computers intended to solve intense numerical calculations. Such calculations include tasks like nuclear simulation, weather forecasting and fluid dynamics.Learn more about Computers & Hardware
Government employees use computers for communication, word and data processing and project management among other applications. Computers have become part of daily life, and like businesses and individuals, federal and state offices use computers in their daily office operations.Full Answer >
The basic difference between analog and digital computers lies in the different approaches they take to handling data. Analog computers are able to deal with continuously varying inputs for complex phenomena such as voltage changes and temperature fluctuations. Digital computers must have their inputs reduced to a simple binary language in order to accurately model the world.Full Answer >
Mainframe computers are used to store large amounts of data that wouldn't fit into a normal-sized computer system. Mainframe computers are most often used by large corporations and government agencies that require a large amount of information to be stored in a centralized secure location. They are named after the large cabinets that were needed to house them when they were physically large.Full Answer >
Some desirable computer attributes include compactness, making the computer suitable for users with limited space, low price, particularly for computers intended only for media playback and Web browsing, and the inclusion of additional connection ports such as HDMI and USB 3.0. For laptops, desirable attributes include light weight, sleek design and the presence of an optical drive for users who consume media from CDs and DVDs.Full Answer >
