What is a computer
The computer is a modern high speed electronic device. Do not work more than two or three with the help of other electronic instruments. But with the help of computers, it is possible to perform many kinds of difficult tasks. The main features of the computer are
1. It can store millions of information,
2. Can execute very fast and accurate instructions. The computer term comes from the Greek compute word. The meaning of compute is counting. Basically the computer's word counting machine. (Again Latin sounds and sounds from computer words computare and) In the past, only the calculation work was done by computers. Computer language based on electronic signals. Computer results reveal on the basis of the computer's instruction through the language of the computer. The computer's language is a computer program. The computer is an inanimate substance without the program.
Computer Definition:
The computer solves the emergence of a set of electrical waves in their own signals and helps to solve the problem with the help of the command implemented by the user. "
Computer Spec:
Computer accuracy, speed, data storage, automatic functioning, tolerance, memory or memory, etc.
Computer Usage:
Office-court can not be found anywhere in the house where computers are not used, in office work, business, business, school-college-university, various types of Computers are used in all the stacks of projects, industries, factories, sports junk, shop jute, bank-insurance company, weather office, seismic station etc.
Computer history History of calculating instrument is reviewed, it is known that about four thousand years ago, Chinese invented a calculator called Abacus. /Called computer ancestor. From now on, modern computers have been discovered by passing through different stages. In 1833, the mathematical design of the modern computer was developed by British mathematician Charles Babbage (charles babbage). Who is called the father of modern computers. In 1944, the electronic computer was invented in the name of Mark 1 (Mark-1) under the leadership of Howard Acken, referring to the idea of the board of business. This computer was created by Harvard University and a group of renowned IBM companies.
The biggest revolution in computers is through the discovery of micro processors. In 1971, America's Intel company first created a micro processor. A micro-processor with a square inch size of less than silicon feet, thousands of transistors inserted a spell. A computer with a micro-processor is a modern micro computer or personal computer.
Computer Categories:
Computer has been divided into four parts in a phased manner. Namely A. Super computer, b. Mainframe computer, c. Mini computer, d. Micro computer
A. Super Computer:
This computer is the largest form of data-processing capability, very powerful and fast speed. This computer is commonly used in scientific research and large organization. Such as cray-1, cray x-mp, cyber-205
B. Mainframe computer:
Although smaller than supercomputer, this type of computer works more like computers than many other computers, keeping the connection between face and emission face, equipment and various helpful memories. Large companies use this type of computer. Eg- univac1100 / 01, ibm 6120, ibm 4341, ncr n8370, data general cs30.
C. Mini computer:
The most popular is that the computer is small in size and cheaper in price. Used in official work, sports and entertainment. This computer is called PC (personal computer). Such as ibm p.c, trs 80, apple 64
D Micro computer:
A microcomputer or personal computer is divided into three categories. Namely 1. Super micro 2. Desktop (desktop) 3. Laptop 1. Super micro: Super micro computer is the most powerful micro computer. The other name is Work Station. The power of this computer is close to any mini computer, because they are occupying the space of miniframes.
2. Desktop:
It can be easily used and installed on desk. Such as IBM PC, Apple Macintosh.
3. Laptop: Small computers are easy to carry and use from the desktop. It can be worked on top (top) over the lap. The laptop is divided into two categories. Such as note book and pda. Note Book: Small diary and notebook-shaped laptop. These are also called the power book. PDA: Sublicense Book PDA (personal digital support) is a type of laptop. In addition to the physical aspects, in a constructive way, the computer can be divided into three categories. Eg -1. Digital computer, 2. Analog computer, 3 Hybrid computer
1. Digital computer:
Such a computer receives information through color / digit signals and publishes results. The computer is precise mathematical and logical work fine. Collect data based on binary numbers 1 and 0.
2. Analog Computer:
Analog uses electrical signals instead of letters and numbers on computers. Acquires electrical waves generated by the sunlight, heat, heat, pressure, as analog computer input and the results draw with the normal plane. Used in analog computers in chemical, petroleum and food processing industries.
3. Hybrid computer:
A computer with a combination of two types of computers and digital computers is hybrid computer. Hybrid computers are used for scientific solutions.
1. It can store millions of information,
2. Can execute very fast and accurate instructions. The computer term comes from the Greek compute word. The meaning of compute is counting. Basically the computer's word counting machine.
