This report discusses the different types of data compression, the advantages of data compression and the procedures of data compression. In computer science, the syntax of a computer language is the set of rules that defines the combinations of symbols that are considered to be a correctly structured document or fragment in that language. The four types of hardware are, Input Hardware: For users to input data into the computer system. A devices BIOS controls the way the device responds to cues from the user at the most fundamental level, such as a computers booting-up process that occurs when the system powers on. uses the Linux kernel, and the Google Chrome web browser with an integrated media player. Driver Software. * The ethics of using computers between the person and the other. CSS property written in a separate file with .css extension and should be linked to the HTML document using link tag. Hence, we have covered some common Types of Software Testing which are mostly used in the testing life cycle. Computer that lies between the largest Multi-user systems (mainframe computer) and the smallest Microcomputers or personal computers. Every computer that is connected to a network has to have a unique MAC Address.
