From the end of the 19th century the word began to take on its more familiar meaning, a machine that carries out amputations Basically, computer is an electronic device that can be programmed to carry out a set of arithmetic or logical operations automatically. Modern computer can solve more than one kind of problem. Typically, a computer consists of a central processing unit (CAP]), and memory. The processing element carries out arithmetic and logic operations, and a sequencing (ALL’) and control unit can change the order of operations in response to stored information (CUE).

Peripheral devices allow information to be retrieved from an external source, and the result of operations paved and retrieved. Originally, computer is used to help simple calculation but development in technology rocketed the usage of computers to conduct multiple complicated tasks. Len the early age, computer were the size of a large room, computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space.

Simple computers are small enough to fit into mobile devices, and mobile computers can be powered by small batteries Nowadays, computers are vital every fields. It helps to ease the tasks y doing complicated calculation. For example in military field, computers are used in specialized military application such as decoding military codes, enemy detection and ballistic calculations. In medical field, computer help to improve the health of people by monitor the health of the patients and analyzed the condition of ones. HISTORY First account of the computer is proposed by Charles Babbage.

Babbage had a vision of mechanical numbers and tables. In the early 19th century, he invented the first mechanical computer designed to help in navigational calculation. In 1833, he legalized that a much more general design, an Analytical Engine. The Engine incorporated an arithmetic logic unit (digital circuit that performs integer arithmetic and logical operations), making it the first design for a general-purpose computer. The first modern analogue computer was a tide-predicting machine invented by Sir William Thompson.

In 1941, Conrad Use came up with Z, the world’s first working electromechanical programmable, fully automatic digital computer. It was quite similar to modern machines in some respects, pioneering numerous advances such as floating point numbers. Replacement of the hard-to-implement decimal system (used in Charles Baggage’s earlier design) by the simpler binary system meant that Use’s machines were easier to build and potentially more reliable, given the technologies available at that time. 5 years later, the Electronic Numerical Integrator and Computer (MANIAC) was constructed by United States Army Research and Development Command. Installed at the University of Pennsylvania, its 40 separate eight-foot-high racks and 18,000 tubes. It was the first electronic general-purpose computer intended to help calculate ballistic trajectories. The development of integrated circuit causes an explosion in the commercial and personal use of computers and led to the invention of the microprocessor. In ass, personal computer started to emerge. The Keenan-l, designed by John V. Blackener, the first personal computer, advertised for $750 in Scientific American. More of PC started to emerge such as Apple I and II, Commodore pet computer and IBM PC Jar.

In the year 1981, Microsoft introduces MS-DOS operating system that ease the users to give command. 21st century is known as the golden age of computer as all is depending on computers. Mobile computers start to emerge. With the continued miniaturization of computing resources, and advancements in portable battery life, portable computers grew in popularity in the sass. The same developments that spurred the growth of laptop computers and other portable computers allowed manufacturers to integrate computing resources into cellular phones.

These smartness run on a device on the market. COMPUTER SOFTWARE Computer software also known as computer program is the non-tangible component of computers. Computer software contrasts with computer hardware, which is the hysterical component of computers. Computer hardware and software require each other and neither can be realistically used without the other. Computer software includes all computer programs regardless of their architecture; for example, executable files, libraries and scripts are computer software.

Yet, it shares their mutual properties: software consists of clearly defined instructions that upon execution, instructs hardware to perform the tasks for which it is designed. Software is stored in computer memory and cannot be touched, Just as a ID model shown in an illustration cannot be touched. How does Software functioning? Software is usually written in high-level programming languages that are easier and more efficient for humans to use (closer to natural language) than machine language.

High-level languages are compiled or interpreted into machine language object code. Software may also be written in a low-level assembly language, essentially, a vaguely mnemonic representation of a machine language using a natural language alphabet. Assembly language is converted into object code via an assembler. Categories of Software Software is often divided into two categories. Systems software includes the operating system and all the utilities that enable the computer to function.

Applications software includes programs that do real work for users. For example, word processors, spreadsheets, and database management systems fall under the category of applications software. System Software Application Software Definition Collection of programs designed to operate, control and extend the processing capabilities of the computer itself. System software is generally prepared by computer manufactures. Software that are designed to satisfy a particular need of a particular environment. All software prepared by us in the computer lab.

Computer hardware is the collection of physical elements that constitutes a computer system. Computer hardware refers to the physical parts or components of a computer. There are many different kind of hardware that can be installed inside and connected to the outside of the computer. The hardware can be divided into two which are internal hardware device and external hardware device. The internal hardware parts of computer are often referred to as component. The examples of internal hardware are graphic cards, sound cards, memory, motherboard and chips.

The external hardware parts of computer are referred as peripherals. External hardware device include mouse, keyboard, WebMD, printer, speaker and scanner. Together they are fall under the category of computer hardware. Category of Hardware Hardware can be classified into 4 category : Input device Output device Processor Storage Input device is the data put into the computer for processing. Common input device are keyboard, pointing device, scanner and source data automation. ) Output Device Output device is any piece of computer hardware equipment used to communicate the results of data processing carried out by an information processing system which inverts the electronically generated information into human-readable form.

It is the center of activity in the computer which interprets and executes program instruction. It also communicate with input, output and storage device. ) Storage Storage devices are hardware devices that are capable of storing information in a computer. The data storage devices come in several sizes and shapes and some are non-removable while other are removable. Some of the storage devices in a imputer include: floppy diskette, CD-ROOM disc, CD-R disc, hard disk drive and USB flash drive. How does the Computer Hardware related to the Medical Science? Computer hardware is very useful in medical science field. The medical officer such as doctor, pharmacist and dentist use the hardware to observe, measure, interpret and record all the information, data and photocopy of the medical material.

For example, a radiographer use an X-ray device (input hardware) to generate X-ray image of a patient. The X-ray device is linked with computer and the image is display at computer screen (output hardware). One of the output hardware that is widely seed in medical field is vital sign monitor. It is an output device used by the doctor to display the information about blood pressure, temperature, pulse and pulse geometry of patient. The storage device is used by the doctor to store and save the patient record, electronic medical report, documents and others.
