- 2. Types of Computers Classification of Computers According to Size and Processing Power Larger computers have higher process speeds, whereas smaller ones provide higher expertise for private computing. Supercomputers- These are the fastest, largest, and foremost powerful in terms of speed and accuracy and perform complicated mathematical computations Uses of Supercomputers In the field of science, researchers use these machines to calculate and model properties of biological compounds like super molecule and human blood. The military uses supercomputers to check new craft, tanks, and a bunch of arms and camouflage. These machines also used to facilitate and decode sensitive information. In amusement, supercomputers are used to facilitate and create a perfect online animated game, sports performance.
- 3. Mainframe- are large-sized computer types just like the supercomputer equally powerful but has the lesser ability in terms of the computation compared to supercomputers. Also popular with business because it can handle massive amounts of data going in and out simultaneously. Uses of Mainframes They are used in large organizations where thousands of clients must access data simultaneously Performs ATM cash withdrawals and deposits. Useful in business transactions that use credit cards or pre-paid cards. Can be used in online electronic transactions.
- 4. Minicomputers- Minicomputers are general-purpose devices and less expensive than a larger system. The processing capabilities of minicomputers are below that of mainframe systems but above the capabilities of personal computers. Also known as mid-range computers. Uses of Minicomputers Usually has switchboard control. Dedicated type of computer for graphics and computer design It has a time-sharing feature that allow multiple users to interact concurrently on a single system. Server-These are types of computers that are very functional and provide resources and services to client computers in a server-client network model. Uses of Server Server computers are a specialized type of machine which has abilities far beyond what personal computers can do.
- 5. Personal Computers / Microcomputers – Microcomputers are the most commonly known as a personal computer or a single user computer system in the market or simply PCs. Because of its affordability price, they are the most used types of computers. Workstations . This computer system works just like a microcomputer or personal computer. However, it has a more powerful microprocessor used for tasks that require a great deal of number-crunching power, such as product design and computer animation. Workstations also single- user computer systems that are often used as network and Internet servers.
- 7. 1. Analog Computers – It is a computer that represents infinitely varying signals of data by measurable quantities such as voltages or frequencies. Analog computer system can be set up according to initial conditions and then allowed to change freely. Example: Thermometer, automobile speedometer, an aneroid sphygmomanometer, telephone lines, water meter, etc. 2. Digital Computers - These computers are the most commonly used high speed programmable electronic devices nowadays that perform mathematical calculations, compare values, and store results. A typical digital computer system has four functional elements: (1)input-output equipment, (2) main memory, (3) control unit, and (4) arithmetic-logic unit. Example: PC, Laptop, Desktop, Mobile/Modern smartphones, Smartwatch 3. Hybrid Computers - A computer that has both analog and digital data features. The digital component usually takes the counting feature that serves as the controller and provides logical and numerical operations and uses. Example: CT scan machine, ATM Machine, Radar Systems, Scientific Laboratory Machines, Weather system machines
