WordPress let you easily customize the contents of the site. A website developed by WordPress has the advantages like a blog too!

What is a Network?

A network is any collection of independent computers that communicate with one another over a shared network medium. A computer network is a collection of two or more connected computers. When these computers are joined in a network, people can share files and peripherals such as modems, printers, tape backup drives, or CD-ROM drives. When networks at multiple locations are connected using services available from phone companies, people can send e-mail, share links to the global Internet, or conduct video conferences in real time with other remote users. When a network becomes open sourced it can be managed properly with online collaboration software. As companies rely on applications like electronic mail and database management for core business operations, computer networking becomes increasingly more important.

In the early days of personal computing computers were usually disconnected from one another. They would be used for document writing and calculations, and special equipment was required to connect them together. Nowadays nearly all computers come with network equipment included so it is easy to join them in a network.

How are networks formed?

Normally a network is controlled by a central link. Sometimes this central link is another computer. Usually in a home it is a small box called a router. This router is a specialised computer.

The computers can be connected to the router through physical cables or through wireless signals. Normally the router requires a password from each computer. This is for security so only trusted computers can access the network. Once computers are on the same network they can share information with one another.

For example, you can copy documents and pictures from one computer to another. When this happens the documents are sent over the network connection to the router, which then sends the data to the destination computer.

All data passed over the network is known as network traffic. The router is like a traffic policeman that directs this traffic down the correct paths. Another benefit to connecting computers together on a network is that they can share their connection to the internet.

The internet is a ‘network of networks’ – it is the network that connects computers from all over the world.

There is no one central router for the internet: there is far too much traffic for just one router to cope with! So the internet is a decentralised network: because there is no centre.

If a router on a home network is connected to the internet then all of the computers on that network can connect to the internet through the router. This is how most homes have their internet connection nowadays.

What is a Computer?

I’m typing this blog on what it quite unquestionably a computer. But what else counts as a computer? A PDA? Yes, no question of it. A smartphone? Almost indisputably, especially given that my iPhone is far more powerful than many PDAs, or indeed many portable computers of only a few years ago. But what about a digital camera?

My question isn’t purely academic. As a keen photographer I’ve followed with both interest and concern the growing number of accounts of photographers being stopped and searched under anti-terror legislation, or harassed by security guards, again often on the pretext of security. A common feature of such incidents is the demand that the photographer delete images on his or her camera. And this explains my question, because I think there is a good case to be made that to do so is illegal under the Computer Misuse Act 1990.

It turns out I have company in high places in this regard. Lord Carlisle, in his 2008 annual report on the operation of the Terrorism Act 2000, notes with concern reports of the use of recent anti-terror legislation against photographers (see paras 195 to 197) and specifically comments that police officers who use force against photographers to, for instance, make them delete photographs, risk liability for both disciplinary and criminal proceedings. What I am suggesting is that irrespective of other liability under such legislation as the Police and Criminal Evidence Act 1984, the CMA may well provide specific protection to photographers.
