Hardware is the term given to the computer machinery and the various individual pieces of the computer. It refers to the physical devices of the computer system. The same hardware can be loaded with different software to make a computer system perform different types of jobs to produce useful outputs.

There are many companies who take annual maintenance charges from the customer and provide complete software and hardware solutions to them. They have their own trained engineers in both the fields (hardware or software) that find the problem and give solution for it.

Networks of the future will be worlds apart from today’s relatively mundane ones that simply carry packets from one end to the other. With the explosion of Peer-To-Peer (pc-to-pc direct data transfer), high definition video streaming and ubiquitous computing projects like Internet are looking at a scenario where even light bulbs and toasters will have an Internet Protocol (IP) address in affect making household compliances capable of accessing as well as being controlled by the internet. Why do these household appliances need to be connected to the internet or even be controlled through the internet

For starters efficient usage of energy and centralized control, following that train of thought we are looking at a scenario where even light bulbs and toasters will have IP addresses and will be hooked onto the internet – networks as we understand them today may be overwhelmed by the load of data. This has naysayers saying how the extra data is going to clog the data pipes flooding them with data rendering them useless whereas others have grave security concerns about the usage of the data.
