Document Summary

Types of software and their differences: custom software is developed to meet the specific needs of a particular customer and tends to be of little use to others. Unlike generic software, users cannot usually replace embedded software or upgrade it without also replacing the hardware. Total processing power devoted to running this type of software. Seg2136 textbook notes: real-time software has to react immediately to stimuli from the environment (e. g. the pushing of buttons by the user, or a signal from a sensor). Much real-time software is used to operate special-purpose hardware; in fact almost all embedded systems operate in real time: data processing software is used to run businesses. It performs functions such as recording sales, managing accounts, printing bills, etc. A key characteristic of traditional data processing tasks is that rather than processing data the moment it is available, it is instead gathered together in batches to be processed at a later time.
