A process is where input is transformed into output. Processing is carried out in the central processing unit (CPU). Some of the processing is carried out by the operating system but the rest is performed by computer programs (note the different spelling to the programmes you watch on a TV). Applications software is a general term for computer programs that enable computer users to carry out specific tasks like word processing or image manipulation. Computer programs are made up from a number of procedures that tell a computer's CPU what to do with the input it receives. These are linked...

Applications software is a general term for computer programs that enable computer users to carry out specific tasks like word processing or image manipulation. Computer programs are made up from a number of procedures that tell a computer's CPU what to do with the input it receives. These are linked together and each one is designed to perform a specific job, e.g. sharpen an image, underline text, perform a methematical calculation etc. Companies who sell applications software re-evaluate their products every so often and write new procedures that can make them do new things or old things just a little bit better. You probably use at least one computer program or application (app) most days. In the world of ICT, procedures, controls and design are all important ideas in building computer programs. They are a sequence of instructions that are written in a language that a computer 'understands' and tells the computer what it should do. A program is a sequence of procedures that run in a certain order, depending on the input received by the computer. The more complicated programs are written using an approach called Top-Down Design. This involves writing the program in small chunks, each one of these is called a procedure. Producing a computer program is often organised by using a flow chart. A flow chart is perfect for this task because it is exactly what goes on in a computer processor, but written down on paper. It provides the computer programmer with a model of how the program should work. This can help them to see if anything is missing. It also shows them how the input will reach the output and the steps needed to perform the processing. Flow charts contain arrows that show which way the data flows. The arrows are joined to different shaped boxes. The shape of each box means something, for example a diamond shaped box indicates a decision is to be made. Show less
