What is an ICT system? :: ICT Essays

ICT and computers ar NOT the same thing. An ICT system is a set-upconsisting of hardw be, softw be, data and the people who intent them. Itvery often also includes communications technology, such as theInternet. Computers are the hardware that is often part of an ICTsystem.This is why your GCSE is non just rough computers, but nearly how,whyand when people use them. It is the power of computers andcommunications that has allowed ICT systems to shape so important.Like any piece of equipment, the important thing about it is what itlets us do.ICT Systems are apply in a whole military of places, from offices, shops,factories, aircraft, ships, and communications to medicine andfarming. They are everyday and ordinary yet ludicrous in how theycan add extra power to what we do and hope to do.ICT systems have become important because by using them we become* more than productive in that we can do more things more apace and at reduced cost.* More accurate and able to work continuo usly.* open to deal with vast amounts of selective information and crop it quickly.* They can charm information rapidly.Types of ICT system-------------------There are different types of ICT system. The main aim of severally systemdecides which name is sometimes used for it.Information systemsMany ICT systems are set up to manage data and information. Examplesof these are a Sports ordination membership system or a Supermarket Stocksystem.Control Systems opposite ICT systems have controlling machines as their main aim. Theystill use input, process and output, but the output may be moving agolem arm to weld a car chassis rather than information. communication theory SystemsYet other ICT systems are dedicated to communications. Their output isthe successful transport of data from one place to another.Input, output & system diagrams-------------------------------What comes out of an ICT systems is for the most part dependant on what you putinto the system. The acronym GIGO is a good way of persuasion aboutthis.GIGO can be interpreted in 2 slipway1. Good Input, Good OutputICT systems work by taking inputs or instructions and data, processingthem and producing outputs that are stored or communicated in someway. The higher(prenominal) quality and better thought-out the instructions, thehigher quality and more useful go forth be the outputs.2. Garbage In, Garbage OutICT systems all fall dash off if the inputs are inaccurate or faultythey allow for either not be able to process the data at all, or willoutput data which is eroneous or useless. Thats why the term GIGO issometimes used to stand for Garbage In, Garbage Out.
