1.SYSTEM SOFTWARE
System software helps run the computer hardware and computer system. It controls the operations of the computer and devices attached to it. The system software is essential for a computer to do the work. Without this software, no link can be created between the user and the computer; it includes operating systems, device drivers, diagnostic tools, server windowing system utilities, and more.
2.OPERATING SYSTEM
An operating system is a program that is initially loaded into the computer by a boot program. It manages other programs on a computer. A few examples of the operating system are Windows DOS, Unix, Linux MAC.
3.DEVICE DRIVER
A Device driver is a program that controls a particular type of device attached to your computer. There are device drivers for printers, displays, CD ROM readers, diskette drivers, and so on. When you buy an operating system, many device drivers are built into the product. For other devices, you may need to load a new driver when you connect the device to your computer. A driver attacks like a translator between the device and programs that use the tool. Each machine has it is own set of specialized commands that only it's driver knows.

Cold boot: When the computer is switched on, the process of starting it is called cold booting.
Warm boot: The process to restart a computer that is already powered on is called warm booting.
6.CONFIGURATION OF DEVICE AND SOFTWARE
Windows configure both the software and the hardware, and software configuration means the relationship of hardware elements to each other and the manner in which they are electronically connected. This configuration enables interaction between all hardware devices.
7. MANAGEMENT OF THE PROGRAMS
The operating system also provides the interface between the programs and the users through the programs and the users. Through the program, the user access other computers other computer resources such as printer backing storages and application programs. Actually, in a program, the built-in instructions known system calls the request services from the operating system.
8.MEMORY MANAGEMENT
The memory unit has a very important role in the data processing. The processor takes data and the program instruction from the RAM. During the process, the data are loaded from the disk to RAM. Memory management in the form of resource management applied to computer memory is to provide ways to dynamically allocate.
9.TIME SHARING
In time-sharing, a single computer process the task of multiple users at the same time. Time-sharing is used when multiple users are connected to a single computer to a communication network.
10.ENTERTAINMENT SOFTWARE
