1. Data is raw unprocessed information. It can be random and disorganized facts and recordings. In that format data is not useful to the computer user. Information is processed data. Processing gives the data meaning which enables the information to be useful to the computer user. Analysis is a form of data processing. The recordings of the average global temperatures for the past 100 years are an example data. That data can be arranged in a chronological order and presented on a graph. That graph can then interpreted and analysed to provide meaningful information on the changing global climate.
2. The Information Processing Cycle can be defined as the series of events involved in processing information. It starts with input followed by processing,…show more content… Random Access Memory is referred to as volatile because its ability to store information is dependent on the presence of a power supply. The memory is lost without the power supply..
4. The two types of computer software are the system software and the application software. The system software includes the operating system, drivers, likers and debuggers. The operating system allows the computer user to have access to the computer hardware. The system software is largely controlled by the computer itself. Application software is usually loaded on top of the operating system and unlike the operating system it is optional. Application software also differs in that it is largely controlled by the computer user. It is used to complete specific tasks such as word processing and sending emails.
5. The Instruction/Machine cycle is performed by the CPU and is composed of four stages; fetch, decode, execute and store. During the fetch stage instructions are retrieved from memory. The instructions are then decoded. At this stage, the instructions are interpreted and are converted into a set of computer commands. At the execution stage, the computer carries out tasks based on the computer commands. At the storage stage the results are written to the computer
