1.0 2.0 INTRODUCTION
1.1 Overview
A computer is an electronic device that receives (input) data, processes that data, stores data and produces results (output). Computer can be classified according to their data representation that is functionality, based on their purpose or based on their physical size.
It’s the classifications that bring about types of computers.
There are four types of computers that is, micro computer, minicomputer, mainframe computer and super computer.
1.2 Justifications
Understanding the types of computers will be helpful in determining whether it’s suitable for the intended purpose. For example if it’s a simple task for an individual or small organization then the microcomputer will be more suitable than a main frame computer which serve large organization.
1.3 In brief
In this essay we define what a computer is in detail in terms of the input, process and output.
The features, purposes, functioning, subclasifications and costs of the four types of computers are also discussed. 3.0 TYPES OF COMPUTERS
2.1 Defining A Computer
According to Saleemi (2009), “A computer may be defined as a machine which accepts data from an input device performs arithmetical and logical operations in accordance with a predefined program and finally transfers the processed data to an output device.
The definition of computer can be viewed broadly in three major cases as illustrated below:
Input
Process
Output
Data and instructions
Execution and storage
Information

“(All computers can perform the functions of inputting, storing, processing, controlling, styling and outputting data and information (Ravichdndran, 2001 pg2).”
It works upon the input data using the issued

    Computer: We are living in the age of modern science. We can see the creation and invention of science all around us. From morning till we go to bed at night we use the invention of science. Computer is one of the greatest and valuable invention of modern science. The word “Computer” came from the Latin word “computatrum”. Basically, computer is an electronic device which has the capability of receiving command and turning the command into result. Computer has also the capability to manipulate, save and retrieve data or information. A computer is an electronic device, operating under the control of instructions (software) stored in its own memory unit, that can accept data (input), manipulate data (process), and produce information (output) from the processing. Generally, the term is used to describe a collection of devices that function together as a system.…

    The basic components of all computer systems whether they are microcomputers or supercomputer all contain six basic building blocks: input, output, memory, arithmetic/logical unit, control unit and files. A computer system needs input devices for entering data into the computer for processing. The most common input devices are keyboards and mice. Input devices have now expanded to other methods such as voice input, magnetic ink character recognition (MICR), Optical character recognition (OCR), scanning bar code label, etc. The output devices are used to produce the results of the processing done by the computer. The most common output devices include computer screen or monitor, printer, or writing output on CD or DVD. Computer memory or main memory holds the program instructions and data. All data flows are to and from memory. Arithmetic and Logic Unit consist of incredibly small integrated circuits on a silicon chip. It is mainly responsible for arithmetic function of addition, subtraction, multiplication and division calculation, logical comparison and decision. Computer files storage devices sometimes called secondary or backing storage is used to store programs and data when they are not being used. Secondary storage is nonvolatile. File devices include hard disk drive, magnetic tape drives, flash drives, and CD or DVD. Control Unit provides the control that enables the computer to take advantage of the speed and capacity of its other components. It controls the sequence of instruction to be executed, controls the flow of data, interpret instructions, and it regulate timing of processor (Brown et al., 2012).…

    This essay is about the three types of computer systems: netbook, desktop, and laptop. They all have a different in function and purpose (they function according to what your needs are). The desktop is perfect if you are looking for a computer that is non-portable, high performance, tough and affordable. However if you are someone who want something a basic computer to surf for online information, or for a starter computer, than a netbook is right for you. However, it is not meant to download huge data or set up large applications. A laptop is an ideal choice if budget is not a major limitation, and if you want a high performance system with greater capacity and high storage. In addition, a laptop is portable. For instance you can take it to class as well as anywhere else that you need to. You have to consider these few essential factors before investing in any computer system to benefit your needs. Therefore now that you understand the chief differences among the three computer systems: netbook, laptop, and desktop. You will be able to choose on that fits your needs.…

    We are all familiar with what a computer is in a specific, contemporary sense. Personal computers (PCs) are found in most aspects of daily life, and for some it is hard to even imagine a world without them. But the term means more than simply the Macs and PCs we are familiar with. A computer is, at its most basic, a machine which can take instructions, and perform computations based on those instructions.…

    A computer is an electronic device, functioning under the control of directions stored in its own memory, which can admit data according to specified guidelines, produce results, and store the results for future use. The main purpose of a computer is to process data into information, or output, that people can understand. Data, or input, is a collection of unprocessed items, which include text, numbers, images, audio, and video. The series of input, output, storage activities, communication actions, and system unit are part of the information processing cycle. In order to complete these functions there are many electrical and mechanical components in a computer called hardware. One advantage of all these components is that they are very reliable and rarely break and need replacing. First there is the input device, which is any hardware component that allows you to enter data and commands into a computer. The advantage of input is that it is consistent, whatever it is given it will produce the same…

    A computer is one of the most brilliant inventions of mankind. Thanks to computer technology, we were able to achieve storage and processing of huge amounts of data; we could rest our brains by employing computer memory capacities for storage of information. Owing to computers, we have been able speed up daily work, carry out critical transactions and achieve accuracy and precision at work. Computers of the earlier times were of the size of a large room and were required to consume huge amounts of electric power. However, with the advancing technology, computers have shrunk to the size of a small watch. Depending on the processing power and size of computers, they have been classified under various types. Let us look at the classification of computers.…
