Topic 1- An ICT system and its componentsBy Leanne and PaigeObjectivesYou will learn about what ICT is and how it is used to create ICT systems for individuals, businesses and organisations.That ICT is part of everyday life and it is almost taken for granted and it is growing all the time.Also, The components of ICT systems and their purposes.What is Ict?ICT: Information communication Technology.ICT concerns any device or system that allows the storage, retrieval, manipulation, transmission and receipt of digital information.Its not just about computers, the C in ICT stands for communications and covers many communications technologies.ICT covers hardware and software such as:ComputersScannersDigital camerasSystems softwareWord-processorsDatabasesSpread sheetsCommunication TECHNOLOGIES SUCH AS:Digital TVDigital radioE-mailInternetBroadbandNetworks (wired and wireless)Mobile phonesGPS (Global positioning systems)VideoconferencingInstant messagingFaxWhat is a System?A system in everyday life is a way of doing things.All systems involve input, process and output.InputProcessOutputWhat is an ICT system?An ICT system is a way of doing something using ICT. Businesses need many different ICT systems including :Systems for paying staff (payroll systems)Stock control systemsOrder processing systemsPurchasing systemsAccountancy systemsPersonal (human resources) systemsE-commerce systemsBanking systemsWhat do all systems have in common?They all involve the three steps of input, processing and output. ICT systems are those where the output from the system goes directly to a human being or into another ICT system.Input: This involves capturing or entering data. In many cases this will involve entering data via the keyboard. The data needs to be encoded.Processing- Means performing actions on the input data. This involves calculations, searching, sorting, arranging, presenting, converting, transferring and classifying.Output- These results are the information produced when the data has been processed. All information systems produce output.The Six components of and ICT system:PeopleAre needed to supply the data to the ICT system and also to make judgements and decisions from the output supplied from the system.The Six components of and ICT system:DataIs the raw material of any ICT system and this is processed by the system to provide the information which is the output produced by the system.The Six components of and ICT system:ProceduresDetermine what needs to be done and when. It also covers the passing of data or information between different people. Administrative procedures are needed to deal with problems such as customers not paying bills, problems with deliveries, etc.The Six components of and ICT system:HardwareThese are the physical components that make up the ICT system. If you can touch it, then it is hardware.The Six components of and ICT system:SoftwareThese are the computer programs which provided the step-by-step instructions to get the job done.The Six components of and ICT system:InformationThe results from processing data. Information is the output from an ICT system.Remembering.Pe DISH ProPe PeopleD DataI InformationS - SoftwareH HardwarePro - ProceduresExam TIpDo not get the steps and stages of computing (input, process and output) mixed up with the components of an ICT system. They do not have any common components.
