Computer System: Concepts, Functions and Types

electronic reckoner body Concepts, Functions and Types forward getting into the detail, it is essential to understand the concept of Computer corpse. Computer strategy is a general purpose thingamabob which pole overlyth be programmed to carry taboo a finite prune of arithmetic or logical operations. Since a sequence of operation can be promptly changed, the in kneadation assisting system can solve more than one kind of chores.In this assignment I exit wrick on the following tetrad different phases. Each phase go forth cover the related bailiwick in detail. In the early serving we give understand the forge of reckoner system. In this part, I go forth discuss the role of reckoner system in different environments. Hardw are, software and skirting(prenominal) component parts of a calculator system. Comparing different types of ready reckoner system.The second learning resultant role is be able to instauration reckoner system in this I will produce a sys tem design specification to meet the clients sine qua non. and then I will evaluate the suitability of a system design specification.Third learning outcome is be able to build and piece ready reckoner system. I this will build and put together a estimator system to meet a design specification, then it will be test and document a data processor system.Fourth learning outcome is be able to undertake routine alimony on ready reckoner system. In this I will discuss performing routine maintenance tasks on a computer system and upgrade the warmware and software on a computer system.In this assignment, each issue process would be discussed in detail to understand the basic concept. breeding termination 01THE ROLE OF COMPUTER ashes IN antithetical ENVIRONMETSIn this young day computer system is used every(prenominal)where, example at Home, Business, Networking, Real-time, Communication. At home the computer is used for normal works like for search information on internet, playing games and and so on for that we dont entreat a high school press forward computer.In telephone line computer plays a big role, totally business there is a finance department, the main activities of the finance department is to indicate all the business transaction, to control the finance cash flow and etc , for that the need a computer.The Networking is all about computers, For Networking computer is important. Without computer, Networking is impossible and we cannot share resources (i.e. files, videos, sounds, pictures, etc) and confabulation between two or more volume will not be possible. For Networking we need at least 2 computers.We use computer system in Real-time. Real-time is a process in which people can communicate without either deadline. We can share our videos and etc. sometimes people use computer as a TV. We can entrance fee to live information from a television station through a computer. Real-time can too refer to event simulated by a computer at same speed that they would occur in real life.Communication is now make worldwide using computer system. Today most of the computers are capable of communication, like we can circularize a message, documents, picture and etc to our friend on the otherwise side of the planet. An nictitation messenger program allows two different computers to converse by type in text or they can even voice confer with each other.THE HARDWARE, SOFTWARE, AND PERIPHERALS COMPONENTS OF A COMPUTER SYSTEMHARDWARE ironware consists of somatogenetic equipments of the computer. The components Hardware are power supply, motherboard, expansion Cards, hard disk and etc. A power supply unit converts alternating current electrical power to low-voltage DC power for internal components of the computer.Motherboard is the main component inside the CPU. it is a large rectangular board with integrated circuitry that connects the other parts of the computer including the CPU, the RAM, the disk amaze and etc.Expa nsion phone card in computing is a printed circuit board that can be inserted into an expansion expansion slot of a computer motherboard or backplane to add functionality to a computer system via the expansion bus.Hard disk is a gizmo for storing and retrieving digital information, primarily computer data. It consists of one or more steadfast rapidly rotating discs, coated with magnetic material and with magnetic heads arranged to frame data to the surfaces and read it from them.SOFTWARE Software is a collection of computer programs and related data that provides the instruction for telling a computer what to do and how do it. There are 3 types of software System software, programing software and Application software.System software is computer software designed to operate the computer hardware to provide basic functionality and provide weapons platform for running application software.Programming software include tools in the form of programs or applications that software de velopers use to create, debug, maintain or otherwise corroborate other programs and application.Application software is developed to perform in whatever task that benefit from computation. It is a set of programs that allows the computer to perform a specific data processing job for the user.PERIPHERAL Peripheral is a device connected to a host computer, but not part of it, and is more or less dependent on the host. These are scuttlebutt/output devices. Peripherals are Keyboard, Mouse, Monitor, Speaker and etc.Keyboard is an input device, which is use to input data by typing.Mouse is a pointing device that functions by detection two-dimensional motion relative to its back uping surface.Monitor is an electronic optic display for computers. The monitor comprises the display device, circuitry, and an enclosure.Speakers are external to a computer that disables the lower fidelity built-in-speaker. They often fetch a low-power internal amplifier.DIFFERENT TYPES OF COMPUTER SYSTEMS A computer is a general purpose device which can be programmed to carry out a finite set of arithmetic or logical operations. There are different types of computer system Personal computer, Workstation, Minicomputer, Mainframe and Supercomputer.Personal computer A personal computer can be defined as a small, comparatively inexpensive computer designed for an individual user.Workstation It is a type of computer used for engineering applications, desktop publishing, software development, and other types of application that require a moderate amount of computing power and relatively high quality in writing(p)al capabilities.Minicomputer It is a mid size computer. In general, a minicomputer is a multiprocessing system capable of supporting from up to two hundred users simultaneously.Mainframe Mainframe computers are powerful computers used primarily by corporate and governmental organizations for critical applications, bulk data processing such(prenominal) as census. In some ways, ma inframes are more power than supercomputers because they support more simultaneous programs.Supercomputer Supercomputer is a board term for one of the straightaway computer currently available. Supercomputers are employed for specialized application that requires abundant amounts of mathematical calculations. encyclopedism OUTCOME 022.1 A SYSETM DESIGN SPECIFICATION TO gather A CLIENTS NEEDSKalba College needs new computer for their college. I went to the college n as per my serve I fuck off make a constitute that how m some(prenominal) computers are required for the college. So I deem represent out that they need total of 180 computers from which 100 will be for computer lab, 15 will be for male staff room, 15 will be for female staff room and 50 computers will be for graphic designing class. The requirements of the college is that they need more holding capableness to store the work, they want the computers to be fast so that no work is delayed and they need high graphic s in the computers so they can for graphic designing.The problem with the current computers running is that the computers dont have enough memory capacity, the speed is very slow and they are not suitable for graphic designing.2.2 EVALUATE THE SUITABILITY OF A SYSTEM DESIGN SPECIFICATIONThe computers we have design for the college is HP. The computers we have design are highly upgraded as the requirements of the college. The computers are made with more memory capacity then the before computers so every work is stored properly. In these computers the speed is also increased by installed more GB ram so that every work is done faster. The graphic card which we have installed, which have made the computers transgress in graphic designing. We also installed a cooling system in every computer so that it stay cool and dont have any problem even if it is used for hours and we also made the backing up woof more easier in every computer so there will be no problem in backing up. We also m ade the security high so that any information is not leaked out and we have installed antivirus in every computer. We are also giving submit maintenance for 8 years if any problem is there with any computer we will fix it or replace the computer.We will differentiate different computers so u will have a better idea that HP Is better than other computers.HPACER dingleIBMHard Disk Drive2TB 7200 rpm SATA hard disk drive1TB hard disk drive1.5TB hard disk drive1TB hard disk driveMemory10GB DDR3ProcessorGraphic cardLEARNING OUTCOME 033.1 BUILD AND CONFIGURE A COMPUTER SYSTEM TO cumulate A DESIGN SPECIFICATIONThe steps in configuring a computer system areSystem installationSystem configurationSystem testingSystem installationOur case has a slide-out tray, first we have to lay the case on its side. because screw in the spacer mounts for bushel the motherboard.Insert the CPU socket to do this, raise the small lever at the side of the socket. Then place the processor, all the pins should slide smoothly into the socket. once the processor in placed lock the lever back down.Dont sink to use thermal paste.Apply the thermal paste to the top of the CPU. This will help to transfer heat from the processor to the water-cooled.Make sure that the cooler is in the correct position.Clips fix cooler to the socket.installing the RAM.The RAM must(prenominal) be suitable for the motherboard.Line up the RAM with its slot before installing it. Then, carefully press the module into the slot.Caution is recommended, as too much oblige may damage certain tracks on the motherboard. It is outperform to push one side down first.Then comes the installation of graphic card, nowadays graphic card are usually fitted in the AGP slot provided specifically for this purpose. The slot are located in the center of the motherboardBefore fitting an expansion card, remove the appropriate slot insert from the back panel of the case.After that install the hard drive before that unendingly leave some space above to prevent heat buildup.Then install the compact disc read-only memory drive, it is similar to installing a hard drive, first check that the jumper configuration is correct and then install the CD-ROM in the case, but careful not to over-tighten the screws as excess pressure can damage it.Now its time to connect the line of productss. The 80-pin ribbon cable is for the hard disk and the 34-pin is for the floppy.Then connect the power supply cables. At last check that all connections are properly, once you have analyse then you can start your PC.We will also install all the peripheral which are required for the college.System configuration First configure Basic input Output System (BIOS) e.g. clock ambits, memory timing, raise order and drive setting. We have done the BIOS setting for all the computers so that there are no problems with the computers. We have installed an anti-virus to protect the computers for any unannounced viruses and we will update the anti-vir us whenever updates are available. We have done everything as per your college requirements, we have set the files and folders sharing permission and we have done all the setting for the peripheral devices.3.2 TEST AND DOCUMENT A COMPUTER SYSTEMSystem testing We will test the system to find any break in it, will check the Power On Self hear (POST) after that we will check the hardware e.g. input/output devices, peripheral devices and then we will test the software to check if its working properly.LEARNING OUTCOME 044.1 PERFORM ROUTINE MANITENANCE TASKS ON A COMPUTER SYSTEMThere are two types of MaintenanceSoftware MaintenanceHardware MaintenanceSoftware Maintenance We will upgrade the software if any update is available. We will update scheduling maintenance tasks, we will also do clean-up, back-up and we will do maintain other third company utility software e.g. compression utilities, spyware removal. If there is any software error we will fix it with in 1 day and we will do a periodic maintenance for all the computers.Hardware Maintenance march on the hardware like installing and configure new peripherals e.g. printers, scanners and etc. Installing additional or replacement devices e.g. hard drive, memory, graphic, sound, optical media. We will monthly do the cleaning of the hardware.
