Hardware Computer Information System has became popular all around the world, due to its rapid growth. In current days, almost every single person is using IS in their daily life. Information System lead to a great change in people`s life style, it is any kind of systems and it consist of six main elements which are people, hardware, software, communication network, data resources, policies and procedures. all of these elements are working together in order to operate more efficiently and effectively(J.A. Obrein. & G.M. Marakas, 1975). Information system use in many areas and the most important area is Business and management in which it support business operation and help manager to make decision . one of the information part is Information technology (IT) which can be defined as "a technology which uses computers to gather, process, store, protect, and transfer information"(A. Dzaja,2011). One of the information system component that people use IS through is a computer. "Computer is a machine that process data and perform computation, and it consist of two main program that are hardware and software"(). Applying Information system in organization and workplace help managers and employees to run their business more easily and quickly, and also, IS will make the work more professional. the most common programs that use in organization are hardware and software. This paper will show the importance of hardware computer. Hardware computer: According to "Introduction to IS" "hardware information system is the physical embodiment of an information system, and it is the main element that make the information system cycle". Enterprise Ireland states that hardware computer program is defined as an "information techno... ... middle of paper ... .... the two registers are first, base register which is holds the smallest legal physical memory address.

An information system is a “collection of software, hardware, procedures, data and computer networks used by people in organizations” (). Managers can use computer-based

Computer hardware engineers research, develop, and test computer systems and components such as processors, circuit boards, memory devices, and many more (Bureau of Labor Statistics). They design new computer hardware, create blueprints of computer equipment to be built. Test the completed models of the computer hardware that they design. Update existing equipment so that it will work will new software. Oversee the manufacturing process for the computer hardware. Maintain knowledge of computer engineering trends and new technology(Bureau of Labor Statistics).
Information system can replace the previous manual handling operations to save a lot of time and labor costs.
And his signal concept of an all-purpose, stored-program computer – the model for our digital devices today – was often attributed to others, from Charles Babbage in the nineteenth century to John von Neumann in the twentieth. (Saler 1)
In the early days of DOS programming, there were many variations, but MS-DOS did not start out as a Microsoft product. CP/M was designed by Gary Kildall, called the man who could have been Bill Gates. As Steve Hamm from Business Week states:
The central unit is the basic part of the computer and includes all the main computer parts. It is the heart of the computer system. It is responsible for executing, or running the software. The software programs are translated into a series of codes made up of 1s to 0s that the CPU can understand. Every code means a certain operation should take place.
Von Neumann architecture, or the Von Neumann model, stems from a 1945 computer architecture description by the physicist, mathematician, and polymath John von Neumann and others. This describes a design architecture for an electronic digital computer with a control unit containing an instruction register and program counter , external mass storage, subdivisions of a processing unit consisting of arithmetic logic unit and processor registers, a memory to store both data and commands, also an input and output mechanisms. The meaning of the term has grown to mean a stored-program computer in which a command fetch and a data operation cannot occur at the same time because they share a common bus. This is commonly referred to as the Von Neumann bottleneck and often limits the performance of a system.
Computers are very complex and have many different uses. This makes for a very complex system of parts that work together to do what the user wants from the computer. The purpose of this paper is to explain a few main components of the computer. The components covered are going to be system units, Motherboards, Central Processing Units, and Memory. Many people are not familiar with these terms and their meaning. These components are commonly mistaken for one and other.
Computer hardware: With the on-going developments in the field of computer system design and architecture, peripherals and processors, hardware helps computing merge seamlessly into our lives. With primary memory capacity reaching up to more than 64 Gigabits, to high resolution LED-displays; hardware accommodates the ever increasing needs of ubiquitous computing.
A computer is a device which is used for several applications; business, gaming, or school. It’s important for people to know how computers work because in this day and age, operating a computer is an everyday task. This complex electrical device utilizes several parts inside of it to keep itself cool, conduct the proper tasks, and maintain stability. These devices can be found several places whether it be on the job, in one’s room, or on a school campus. Computers are essential for everyday use in order to complete what is required. What each component is and its function will be described.
Conventionally, a computer consists of at least one processing element, typically a central processing unit and some form of memory. The processing element carries out arithmetic and logic operations, and a sequencing and control unit that can change the order of operations based on stored information. Peripheral devices allow information to be retrieved from an external source, and the result of operations saved and retrieved.
The next CPU was the 386, this is also no longer produced it had a slightly faster running speeds which are between 16MHz to 40MHz. This CPU could carry out effective multi tasking operations. It also had a substantial improvement in both memory management and it had an enlarged instruction set. It is also the minimum CPU for running windows. It came in two types the 386 SX and the 386 DX. The SX had a 32-bit internal data path but it only had a 16-bit path between the CPU and the computer memory. The DX on the other hand had a 32-bit data bus between the CPU and the memory chips allowing larger data transfers so it had faster through put. It also was able to use external cache memory, usually about 64k, which also improved performance. The 386 came in two different types they both had a internal bus width of 32 bit, the SX had a address bus width of 24 bit, and a external bus width of 16 bit, its internal and external speed was between 16MHz – 33MHz. The DX however had an address and external bus width of 32 bit, its internal and external speed was between 33MHz–40MHz.
