The Computer Network system is the combination of software and the hardware of computer that send data from one location to another location. Its mean sending data from one system to another system is the Computer Network system.
The hardware is the physical part of the computer that carries signals from one network point to another point of network. The hardware is that part of computer that we can touch.
The software contains the set of instructions mean sets of information that make services possible that we suppose form a network.
We can compare two tasks, the networking task to solving mathematics problem task with a computer. Computer hardware do the fundamental job of solving the problem with computer. However, if just hardware is involves this is a very uninteresting task. For storing and manipulating the data, we need Bridging hubs for every memory location. If the software is available, the task is much easier.
The example of networking is the sending email form one computer to another computer. This performed by using software and hardware. The network is need to sending email form world one place to another place of the world. There is a different package of software in networking to perform tasks. Every package of software use the services of another package of the software. Like signals sent form source device to the destination device.
