What is an ICT system? :: ICT Essays

ICT and computers argon NOT the same thing. An ICT system is a set-upconsisting of hardware, software, data and the people who use of goods and services 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 not just about computers, precisely about how,whyand when people use them. It is the power of computers andcommunications that has solelyowed ICT systems to become so important.Like any piece of equipment, the important thing about it is what itlets us do.ICT Systems are used in a whole host of places, from offices, shops,factories, aircraft, ships, and communications to medicine andf encircleing. They are everyday and ordinary yet extraordinary in how they flush toilet join on extra power to what we do and want to do.ICT systems have become important because by using them we become* More productive in that we can do more things more quickly and at reduced cost.* More accurate and able to work continuously.* Able to deal with vast amounts of information and process it quickly.* They can transport information rapidly.Types of ICT system-------------------There are different types of ICT system. The main aim of each systemdecides which name is sometimes used for it.Information systems many a(prenominal) ICT systems are set up to manage data and information. Examplesof these are a Sports Club 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 arobot arm to weld a car chassis rather than information.Communications SystemsYet other ICT systems are dedicated to communications. Their output isthe successful transport of data from sensation place to another.Input, output & system diagrams-------------------------------What comes out of an ICT systems is largely dependant on what you putinto the system. The acronym GIGO is a good way of thinking aboutthis.GIGO can be interpreted in 2 ways1. 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 quality and better thought-out the instructions, thehigher quality and more useful will be the outputs.2. Garbage In, Garbage OutICT systems all fall down if the inputs are inaccurate or faultythey will 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.
