·         The BIOS (basic input/output system) gets the computer system started after you turn it on and manages the data flow between the operating system and attached devices such as the hard disk, video adapter,keyboard, mouse, and printer.
·         The boot program loads the operating system into the computer's main memory or random access memory (RAM).
·         An assembler takes basic computer instructions
 and converts them into a pattern of bits that the computer's processor can use to perform its basic operations.
·         A device driver controls a particular type of device that is attached to your computer, such as a keyboard or a mouse. The driver program converts the more general input/output instructions of the operating system to messages that the device type can understand.
·         According to some definitions, system software also includes system utilities, such as the disk defragmenter and System Restore, and development tools such as compilersand debuggers

System software and application programs are the two main types of computer software. Unlike system software, an application program (often just called an application or app) performs a particular function for the user. Examples (among many possibilities) include browsers, email clients, word processors and spreadsheets.
