Explain the Role of Computer Systems in Different Environments
Explain the Role of   education processing  agreement  brasss in Different EnvironmentsIn to sidereal days era,  data processor has  buy the farm one of the   hatfulonical needs for human beings. Computer which we use like every day was invented for solely one purpose i.e. for calculating numerical problems and mathematical calculations. The  depot  calculating machine is derived from Latin world called comput ar which  fashion to calculate. With the advancement of technologies,  data processor has become one of the  springful machines ever created. There  atomic number 18 different environments or surroundings where figurers  ar  employ. For example, people  idler communicate from one   division to  some other place or from one country to another. Similarly, people can withdraw their money from the bank even living in another country.Some of the  atomic number 18as or surroundings in which  estimators  atomic number 18 used   ar as followsScience and technologiesComputer has become    one of  major role in the in the science and technological area. Scientists can per crap   leave aloney-nilly experiments like nuclear testing, radioactive experiments, space programmes  and so on Similarly, they can  delay their records of their experiments, journals etc that can be retrieve whenever they wanted. Also they can get information on various subjects like weather forecasting, earthquake, volcanic eruption etc.Medicine A computer system has played a major role in field of medicine. Now doctors can perform  detailed operations like heart surgery and others due to advancement of  checkup instruments. Similarly, in pharmaceuticals, people working in these areas can keep the records in computer like manufacture date, date of supplies, and expiry date of medicines. presidential termOfficesBanksHomeTask 2  rationalize the,  ironware,  software package and peripheral  offices of a computer system.As stated earlier, a computer is an electronic device. That means a computer consi   sts of a wires, components that helps to  persist a computer.  basically, there are two parts or components that help to run a computer. They areHardware.Software.Parts of computerHardwareHardwareSoftwareHardwareA  physiological component that helps to run a computer is called hardware. Simply saying,  whatsoever parts of a computer which we can see, feel and touch is called hardware. The examples of hardware are as followsKeyboardIt is  alike one of the input devices. It is used for  go into textual data that consist of alphabets, numbers, special characters etc. The following are the different  graphic symbols of keyboard105 keys desktop keyboard85 keys laptop keyboardVirtual keyboardWi-Fi keyboard pussyfootIt is a pointing device used to position cursor on screen. It has 3  goings. They areLeft buttonRight button inventory buttonThere are mainly two types of mouse. They are as followsScroll mouseIt has ball at its base that is use to roll  everywhere mouse pad.Optical mouseIt has    LED base which emits light. This light is used to position cursor deflection. It does not require mouse pad.MotherboardIt is the main component of CPU cabinet that houses the entire electronic component inside a computer.hard discA hard disc is a physical component that is used for storing data. A hard drive can  barge in millions of data permanently i.e. the data will be stored even if the power is off.RAM RAM is known as Random Access Memory. It is also called volatile memory because it saves the data temporarily when the computer is on. When the computer is  morose off, all the data that is stored or saved by RAM will be deleted.SoftwareSoftware is a set of instructions that helps to run the computer. Or a set of programs used as info systems is called software. Basically there are two types of computer. They areSystem softwareSystem software deals with the internal functions of a computer. It loads when a computer starts and is used for interaction with the hardware. Example op   erating system, device drivers etc. run systemOperating system consists of programs that manage all operations of computer.The main tasks performed by operating systems are as followsBootingBooting is the process of starting the computer and lading operating system with system files. The system files are followsCommand. ComConfig.sysAutoexec.batAfter checking the configurations of the systems and  gear up ok operating system loads/ prepares desktop/laptop for  exploiter. credentialsA computer requires security data stored in inside it. To  go away assets to appropriate  exploiter authentication process (username, password) is followed. If incorrect password is found, user is denied assets. Files are protected by taking password for each file.NetworkingThe computer files, programs, I/O devices etc. Can be shared by networking. Networking allows two or more than two computers to be connected to each other. Networking also allows sharing of interest connection for browsing web-pages.Ta   skOperating system executes different tasks. Each task means process. So, multiple processes are executed and each process request resources. lotion softwareThe software used for fulfilling the requirement of the user is called application software. It is used by computer user after computer finishes starting (booting). Example MS-Office, tally, games etc. Application software are created to fulfil the requirement of a computer user needs.Peripheral componentsThe parts of the computer that helps in running a computer is called peripheral component. These types of component generally found inside or  away of casing cabinet of a computer. We can also say that the components or devices that provide input to the computer or receive output are called peripheral components. Some of the examples are as followsPrinterMouse signature screenMicrophoneVideo cameraTask 3  oppose different types of computer systems. Consider the todays mini world uses different types of computer for different pu   rposes, your first task is to identify and list different types of computer system based on working principles, size and brand. Then explain their available features, application areas and finally suggest which types of computer system would be suitable for above environments.As stated earlier, a computer is a powerful machine ever created by humans. A computer can complete its task within fraction of seconds. The higher the power, the time  taken is less. A computer is generally divided into four types on its  bunsOn the basis of operations or work.On the basis of size.On the basis brand.On the basis of function.On the basis of operations or workOn the basis on  playing an operation or doing a work, computer has been categorised into three types. They are as follows one-dimensional computersThese types of computers works in continuing ranges of values. The results given by these computers are  guess since they work continously in their related fields. It generally deals with the ph   ysical quantities like speed,  compress etc. The examples of analog computer are speedometer, sthethescope,barometer etc.Digital computersThese type computers are usec in binary digits i.e. 0 and 1. It is genrally used as on and off operators. The results given by the digital computers are correct and are more reliable than analog computers. They are used in performing complex mathematical probles and engineering.Hybrid computersHybrid computers are combined form of both analog and digital computers, hybrid computers
