Devices of Computers Computers perform the input, storage, processing, and output functions of the information system. In addition, computers and their devices need ways to communicate with one another. These devices are usually connected by electronic cables when located near each other. The factors that determine the reliability of an information system are the accuracy of data input, the convenience and quality of output, optimal use of storage devices, and the speed of a computer. Accuracy
several other devices work together to makes up a computer system. One part has little value without the other. The components need each other to fulfill their potential. The way the components interact allows people to use the computer to complete many different tasks (Ambrose, 2005, p. 58). The purpose of this assessment is to recognize computer system hardware components including devices that perform the functions of input, processing, data storage, and output. The document will briefly describe
processing unit, we also can all it processor. CPU is like the brain of a computer. The computer's CPU contains a logic circuitry that can handle or carry out all the instructions of a computer program. There are two components in CPU; the primary components of CPU are control unit (CU) and arithmetic logic unit (ALU). The control unit is use to interprets the instructions from software and hardware running to the computer and directs all the operations of processors. The arithmetic logic unit is

It can be used for both productivity and entertainment purposes. 2. Hardware- Electronic devices that make up the physical aspects of computer. Each component specialize in doing certain actions, yet needs the other devices in order to work properly. Ex. Graphic cards process graphics but needs the
Computer Information Systems Once upon a time, way back when in the caveman era, caveman used drawings on walls to keep track of information and to communicate with each other in the clan of one's life-span. Over time, man have improved and evolved in the way of keeping track of information and communicating with one another. Today, one finds himself more in an automated world than he did 25 years ago. When planning to purchase a computer, one must take in consideration all possibilities, options
closer look at data input and also data output considerations. There are many different choices when it comes to data input/output options. While it is good to have many choices, there are usually some considerations that are required to make the best possible decision. The second section of this paper will concentrate on the difference between primary and secondary storage. Lastly, the different roles of computer components and their impact on overall computer speed will be explored. Data Input considerations
Introduction Computer memory refers to any physical device that has the ability of storing information either permanently or temporarily. For instance, the Random Access Memory (RAM) is a volatile memory that has the ability of storing information on various integrated circuits that are used by not only the operating system, but also by the hardware and software. In essence, there are two major types of computer memory namely Read Only Memory (ROM) and the Random Access Memory (RAM). ROM refers
Data Input, Output, Storage and Access Methods The purpose of this paper is to highlight some best practices for data input and output. In addition, this paper will highlight appropriate uses of various storage means. Lastly, it will address the effect certain components of a computer have on its overall speed. Accuracy of Data Input There are various methods for entering data into a computer system. Depending on the medium in which the original data is contained, and how it is to be stored
The Different Types of Memory Devices This technical report will look at various different memory devices and how they are implemented in a standard computer system. Internal memory devices such as ROM, PROM, RAM, SRAM, DRAM, SIMM and DIMM will be looked at in order to give a clear idea of how each one operates, and external devices such as memory sticks will also be touched upon. Each of these devices uses different types of memory in different ways. Over the course of this report, each
unit is the main part of a personal computer. The system unit includes the chassis, microprocessor, main memory, bus, and ports but this does not include the keyboard or monitor, or any peripheral devices (Enterprise). A system unit is also known as a “Tower” or “Chassis”. It is the main part of a desktop computer. It also includes the motherboard, CPU, RAM and other components. (Techterms, System Units) A Motherboard is the main circuit board of your computer and is also known as the mainboard or
The Components of a Computer and Information Processing System In today’s world, computers are everywhere. People use them in a wide range of ways in every aspect of life whether it is interacting with friends, cooking a meal, or transferring funds from one account to another. However, many people do not think about the many aspects of computing and the various devices and software that are part of the information process. Basics of the Computer A computer is a device that can be programmed to
The Importance of Data Accuracy The accuracy of data input is extremely important. There are several types of data input. They all provide different aspects of data accuracy. There is Copy and paste method, Typing of data input manually, Verbal through voice recognition & Verbal to a stenographer, importing from other resources. Handwritten & Scan tron scanners, network sharing, Bar Coding, Bar Scanners, Punch out Tads such as the one used in the presidential election in Florida. I in the following
One of the fundamental and core functions of computers is data storage. The computer has components that retain digital data and record media used for computation. The data stored is in form of bits and bytes. Fast but temporary storage in the computer are often referred to as memory while storage can refer to the storage devices that are not directly accessible, by the Central Processing Unit. Computers use several memory types organized in a storage hierarchy, in the Central Processing Unit. The
Data Storage A computer contains various components such as input devices, output devices and CPU etc. We also use a number of other things such as instructions, program etc. All these are of no use if you do not have data to work with. Data can be stored only in the data storage unit. A storage is the essential component of any digital computer. It is required in a computer to store programs and the data processed by programs. Modern computers have incredible speed of processing because of fast
Buying a computer today is much more complicated then it was ten years ago. The choices we have are abundant, and the information we must gather to make those choices is much greater. The average consumer is a more educated buyer; they at least have some ideas of what they want in a computer. Yet, we must still ask ourselves these significant questions; such as: What will the primary function of my computer be? What computer components should I consider at the time of purchase? How much money do

Q:1What is the difference between cache memory and RAM?(5 lines only) Ans: RAM is abreviated as Random Access Memory, is the main memory of computer in which the running programe is stored temporarily , it losts its memory when computer is turned off. While Cache memory is a special memory used to decrease the average time taken by RAM to access the programe. Cache memory is smaller memory as compared to RAM but it is much faster then RAM. Q:2There are three types of printers what are they? Give
3. Though computers have had a very large effect on society, its uses can be perceived from a positive point of view and a negative point of view because technology has an effect on economic and cultural growths; and, growths as an individual (My Essay Point, 2015). The two most positive impacts of computing would be easy information access and fast, accurate data processing; whereas the two most negative impacts of computing would be family and leisure interruptions, and a loss of privacy.
