Let's look at a network first. A network is a connection of 2 or more computers. Yes as simple as that yet complicated enough for universities and corporates to deploy brightest men of the nation to work on this aspect of technology!!!
Sorry for the lil digression but had to state the importance of a network. Anyhow so network is essentially two or more computers talking to each other. The Internet or the World Wide Web that often visit is a mega-mega-huge collection of such computers tied together. The information that we see online is stored in some remote memory location monitored and controlled by another computer.
There are certain things that make computer networks a bit complicated than it seems. Here are some of the critical issues that need a close attention while designing a network:
- Number of computers (also called as nodes)
- Medium of communication: wired (optical/electrical) or wireless
- Protocols or language of communication
- Physical distance between nodes
- Number of users on the network
there are many other technical issues which I will cover over the next few blogs.
