Unformatted text preview: s is purely role-based and may change dynamically as the role of a computer changes. Figure 20.9 summarizes and presents a relative comparison of different types of computers based on some key features. Points to Remember 1. Traditionally, computers were classified by their size, processing speed and cost. Based on these factors, computers were classified as microcomputers, minicomputers, mainframes and supercomputers. However, with the rapidly changing technology, this classification is no more relevant. 2. Today computers are classified based on their mode of use. According to this classification scheme, computers are classified as notebook computers, personal computers, workstations, mainframe systems, supercomputers, and clients and servers. 3. Notebook computers are portable computers which are mainly meant for use by people who need computing power wherever they go. They are small enough to fit inside a briefcase, light enough to be easily carried around, and are designed to operate with chargeable batteries so that they can be used even at places where there is no power point available. They normally run MS-DOS or WINDOWS operating system and are mostly used for word processing, spreadsheet computing, data entry, preparing presentation materials, and making presentations. 4. A personal computer is a non-portable general-purpose computer that can easily fit on a normal size office table and is generally designed to be used by one person at a time. PCs are mainly used to meet the personal computing needs of individuals either in their working places or at their homes. They are also used both by children and adults for education and entertainment. They normally run MS-DOS, MS-Windows, Windows-NT, Linux, or Unix operating system and support multitasking, which eases user operation and saves lots of time when a user has to switch between two or more applications while performing a job. 5. A workstation is a powerful desktop computer designed to meet the computing needs of engineers, architects, and other professionals who need greater processing power, larger storage, and better graphics disp...
