Life is a pre-programmed process, and there is a system under system. It’s difficult to explain but the first thing what we need to understand is the basic phenomenon of a computer system.
A computer system is a machine that is able to take sets of instructions in the form of inputs, manipulating the data and providing us output. The process is completed by the combination of hardware and software. The computer has one or more inputs to provide data (Desired result).
For processing to take place, there needs to be set of instructions of what needs to be done. This set of instruction is known as program, and the set of programs called software. to setup for a computer program we need to install it. By installing of a computer program we are making the program ready for execution including operating system.
It’s already explained Operating system is a specialized program which tells the machine how to work, an operating system is a collection of software that manage computer hardware and other programs. Without an operating system application programs and a device cannot run. There are many kinds of an operating system. Early computers were built to perform a series of single tasks, like a calculator, but now each day there is a new version of software coming after applying newer and better changes, which will give us efficiency on the work and time saving too. For large systems, the operating system has even greater responsibilities. It’s like a controller. There is different kinds of OS-
Multi-user: Allows two or more users to run programs at the same time. Some operating systems permit hundreds or even thousands of concurrent users.
Multiprocessing: Supports running a program on more than one CPU.
Multitasking: Allows more than one program to run concurrently.
Multithreading: Allows different parts of a single program to run concurrently.
Real time: Responds to input instantly. General-purpose operating systems.
The basic computer hardware is CPU (Where the inputs are processed to give us the desired result in the form of data’s, Monitor (Display Device), Keyboard and Mouse for inputting the instructions.
The basic idea of a computer system is Input Information > process > output Information. Inputs are the command that are entered to a computer system via input device such as keyboard or mouse its like we input our voice through the microphone and it’s converted into digital data via sound card.
Similarly, there are millions and billions of cells in body, blood, hair, organs, etc. the brain works as CPU, we see the world through the eye, each and everyone has a separate role and system within the human body. Life cannot be predicted, only a mind-controlled system of things can be predicted. There is a networking takes place inside our body system; a computer network consists of several computers that are connected to one another using devices that allow them to communicate. If your computer network is wireless, it would not require that they be connected using hardware. When the computers are connected via a computer network they are able to transmit files from one computer to another. These computers are also able to connect to the internet using one connection.
