What Is The Classification Of Computers?

For computational purposes, these computers use analog components and for storage, digital memories are used. It sought for, and asked Gary Kildall, a consultant, to write an operating system for its new baby. Hybrid Computers These type of computers are designed to process both analog and digital data. Input was based on punched cards and paper tape. It can store the same amount of data and having a memory of the same size as that of a personal computer. This phase of computers saw introduction of keyboards that could interface well with processing system. The technicians wired up electrical circuits by connecting numerous cables to plugboards.

History of Computer Development & Generation of Computer

According to size • Supercomputers • Mainframe Computers • Minicomputers • Workstations • Microcomputers, or Personal Computers Supercomputers : are widely used in scientific applications such as aerodynamic design simulation, processing … of geological data. The capability to gather data at high speeds and to process data at uniformly high speeds, makes analog computers exclusively suited to controlling processes of oil refineries, weapon systems steel mills, and similar other procedures. By using terminal users put inputs into the computer and get the output through screen. Any example of a hybrid computer is the integrated computer used at the Space Launch system when sending Astronauts in the space for scientific research and exploration. Minicomputers A larger computer normally consists of modules accumulated on a chassis and is terms as a mainframe computer. In this Webopedia Study Guide, you'll learn about each of the five generations of computers and the advances in technology that have led to the development of the many computing devices that we use today.

Classification of Computers

classification of computers according to generation

The technology of integrated circuits improved rapidly. Even though the assembly languages proved to be great help to the programmer, a search was continued for still better languages nearer to the conventional English language. Besides the development of operating systems software, other commercial applications were also hitting the 'shelves'. . They had enough power to perform the basic recreational activities that people owning personal computers required. The sealed glass allowed current to flow wirelessly from the filaments to metal plates. Thus any computer which solve problem by translating physical conditions such as flow, temperature, pressure, angular position or voltage into related mechanical or electrical related circuits as an analog for the physical phenomenon being investigated in general it is a computer which uses an analog quantity and produces analog values as output.

They have primary storage in hundred to three hundred megabytes range with direct access storage device. Such computers process data into a digital value in 0s and 1s. Most major developments from the 1940's to present day have resulted in increasingly smaller, cheaper, more powerful and more efficient computing devices. This allowed systems to run different applications at a time. Special-Purpose Computers - as to the name implies, is designed to perform one specific tasks. These kinds of computer represent the physical quantities, such as distance, acceleration, velocity, temperature, or angular position, pressure, force etc.

This was the major problem of this generation of computers. Just like vacuum tubes, transistors are switches or electronic gates used to amplify or control current, or switch electric signals on and off. Analog computers process data represented by physical variables and output physical magnitudes in the form of smooth curves,or rather sine or cosine waves. Terminals: Although terminals look like the personal computers, they have some limitations when compared with personal computers. Actually, when we optimize a mainframe computer then we get super computer. This is referred to as a distributed data processing system. The computers were smaller in size due to the introduction of the chip.

They came in time to replace the electromechanical systems which were way too slow for assigned tasks. Form factor: Laptops: Portable, but slower and smaller screen. Which ultimately led to the development, birth and rapid evolution of the Internet. It featured a never before seen graphical interface and the mouse. These computers had the following characteristics: They used vacuum tubes for circuiting. Many other smaller, less powerful computers otherwise known as terminals are networked with the mainframe, meaning they are attached to the central mainframe computer.

By using terminal users put inputs into the computer and get the output through screen. According to functionality, Type of computers are classified as : Analog Computer An analog computer spelt analogue in British English is a form of computer that uses continuous physical phenomena such as electrical, mechanical, or hydraulic quantities to model the problem being solved. The mainframes are able to process 1 to 8 bits at a time. If you're still not sure, I'd get a Dell Inspiron desktop or laptop if you want Windows or linux , or a MacBook air or 21 inch iMac if you want a Mac. A computer can be as big as an entire room or as small as a microcontroller found in mobiles and embedded systems. Intel's first microprocessor, the 4004, was conceived by Ted Hoff and Stanley Mazor.

It was an important invention in the computer field. Computers now used operating system software to manage computer hardware and resources. They would be a waste of technology if they could not perform the best of their ability and meet the standards that we have in place for them. This enabled these machines to run several applications at once using a central program which functioned to monitor memory. Second-generation computers still relied on punched cards for input and printouts for output. All the human beings in this world communicate with each other by a language. These computers are extremely expensive and the speed is measured in billions of instructions per seconds.

Another example is a Modem. Sometimes knowingly and sometimes unknowingly we use computers. This was later done using computers. A technique that allows many people at terminals, to access the same computer at one time is called time sharing. Thus an analog computer measures continuously. Mainframes are used by banks and many business to update inventory etc.
