This document defines key terms related to ICT systems including: - What is ICT? Any activity involving input, processing, storage, and output of data. - What is a system? A collection of components that work together to achieve a common goal. - What is an ICT system? A system that uses digital technology to input data, process it, and output information to humans or other systems. - The document then discusses the components of an ICT system including input, process, output, feedback, data, information, hardware, software, procedures, and people. It provides examples for each. Finally, it assigns homework from textbooks and warns of detention for incomplete or late work.

4. Use of technology for input, process, storage and transfer of data and the output of informationWhat is ICT

5. Any activity that involves input, processing and outputE.g. Digestive systemWhat is a system?

6. A system that uses any form of digital technology, the output goes directly to a human being or into another systemsA system that uses any form of digital technology to input and process data and out put the information which goes directly to a human or into another system.E.g. online holiday booking systemWhat is an ICT System?

7. Entering data into the computer or other deviceExamples:PIN numberBarcodePhone numbers on a mobile phoneINPUT

8. Manipulating (calculating, querying, searching) the input data into information that is understandable to the user.Example:Identifying customer account and balance in relation to PINCounting the number of items purchased and adding up the amount of money owedSearching the contacts in your mobile phone, identifying the correct entry and activating a callPROCESS

9. Presenting the information to the user, it must have a context. It could be printed, displayed, heard or in another form.Example:Onscreen presentation of available balance or printed outputReceipt printed for items purchased, showing individual item costs and total priceDialing tone initiatedOUTPUT

10. Input is capturing the data, process is converting the data into information and output is the information produced.Feedback might then be used to affect another input (into the same system or a different system)IPO diagrams can be drawn to illustrate this process in a systemInput Process Output (IPO)FEEDBACK – Enough money in the account to withdrawINPUTPIN:4268PROCESSIdentify PIN code and match to customer account.OUTPUTCustomer details and available balance presented on screen

12. An example of an ICT System is an Management Information System (MIS).Large organisations use these systems at a strategic level (Principles, Managing Directors, Leaders of a business)They use them to help collate and analyse data from other systems e.g. HR Systems, Transaction Processing SystemsWhat are the 6 components of an ICT system?

25. Data is backed up on remote serverData is raw facts and figures or a set of values, data has no meaning.Examination Results (DATA) : 3312, 2, 35, 3, 64, 4421, 2, 48, 3, 56What is Data?

26. Information is data that has been processed and put into context to give it meaningExamination Results (DATA) : 3312, 2, 35, 3, 64, 4421, 2, 48, 3, 56The candidate number has been processed, the student found. The course code has been processed and matched to the student, the score for each course assigned to that student. This information can then be output in the form of a report or graph.What is information?

27. Physical components of an ICT system e.g. Printer, scanner, monitor, server, switchesIn many systems data is transmitted from one computer to another.What is Hardware?
