Types of computers
- 2. CLASSIFICATION OF COMPUTER Computers can be classified into the following two categories: Classification according to the size Classification according to logical used
- 4. ANALOG COMPUTER Thesecomputers recognizedataas acontinuous measurement of physical property. There input is usually in the from of reading on dials or graphs, voltage, pressure, speed and temperatureare some of the properties thatcan be measured in thisway. The examplesare: 1) Service station processor that gasoline pipe contains an analog connects Fuel f low measurement into quantity and pricevalues. 2) Automobile speedometeretc…
- 5. DIGITAL COMPUTERS These are high speed programmable, electronic devices that perform mathematical calculation, compare values and store theresults. These are used for the logical andarithmetic operation. Examples of such computers arepersonal computer.
- 6. HYBRID COMPUTER Hybrid computerarecomputers thatexhibit featureof analog computer and digitalcomputers. Someof hybrid computersystemwas HPC-100, GUS- 100 and HRS-100
- 8. Microcomputer Microcomputer refersto small computers which can be used by individuals at home or in business. The two subcategoriesof microcomputers areas follows :
- 9. HOME COMPUTER In these computers, aCPU and the key board from single unit and TV can be connected to it as the monitor. For storing the data and programs, audiocassette players can beused. These are generally used for home entertainment and education purpose.
- 10. PERSONAL COMPUTERS The Personal Computer has all the functional element found in a large system like CPU, the Input/output devices connected to the CPU and storage devices to storethe data. There are the computers which are used in theday today functioning .
- 11. MINI COMPUTERS The Mini Computer was bigger than the micro Computers and issupposed to be morepowerful. Mini Computers aregenerally designed to simultaneously handle the needs of many users. They can support alarger numberof usersata time with the concept of time sharing.
- 12. LAP TOP COMPUTERS LapTop Computer is a brand of microcomputer, which can be accommodated in a small bag and electricity. Apart of this, computerworks like LCD monitor. Lap Top is generally used in training programs, industrial establishments and exhibitions where it is not possible tobring the other forms ofcomputer.
- 13. MAINFRAME COMPUTERS These are large andpowerful computers, which are used for complex and lengthy computation, used in scientific and engineering application. These computers can support large number of input and output devices. Mainframe computers can provide all the processing power needed by an organization from acentral site.
- 14. SUPER COMPUTER The most powerful computers are • the super computers. Many processing units are integrated together to perform billion of scientific and arithmetic operations every second. Super computers play a vital role in areas of defense, molecular structure analysis, medicines, industry and space exploration. CRAY 1, XMP, CRAY-2 are some models of super computers .
- 15. WEARABLE COMPUTER Wearable computing devices can range from providing specific, limited features like Heart Rate Monitoring and pedometer capabilities toadvance “smart” function and features similar tosmart phone or smart watch.
- 16. PALM COMPUTER The small computer that literally fits in yourpalm. Compared to full size computer, palmtopsare practical for certain function. Palmtops use pen rather than a keyboard forinput. palmtops also calledPDAs and hand held computers
