What is system software
System software is a type of
computer program designed to run computer hardware and applications. If we
think of a computer system as a layered model, what are system software
is the interface between hardware and user applications. The operating system
(OS) is the most famous example of system software. The OS manages all other
programs on the computer.
Other examples of system software are:
• The BIOS (standard input/output
system) starts the computer system after switching on and manages the data flow
between the operating system and connected devices, such as the hard disk,
video adapter, keyboard, mouse and computer. Printer.
• The startup program loads the
operating system in the main memory of the equipment or RAM (Random Access
Memory).
• An assembler takes basic instructions
from the computer and converts them into a bit pattern that the computer's
processor can use to perform its basic operations.
• A device driver controls a specific
type of device that is linked to your computer, such as a keyboard or mouse.
The controller program converts the most common input/output instructions from
the operating system into messages that the device type can understand.
Besides, the system software may also
include system utilities such as defragmenter and system restore, and
development tools such as translators and debug applications.
System software and
applications are two types of computer software. Unlike system software, requests
(often called applications or applications only) perform a specific function
for the user. Examples include browsers, email programs, word processors, and
spreadsheets.
