Dear Reader,
As a newbie I started to find out more about some techie terms I have found i different articles, on the internet or different documents I have been reading for a while and I thought would be nice to be able to share my knowledge to you too, to the new newbies who might struggle to find the same information on the websites about these. In fact, I decided to put all the documents together and form a kind-of On-line Encyclopedia with everything you need to know about computers, and to make things easier, I divided all the material into easy chapters for dummies. :)
So, please enjoy and do not forget to write down your own comments and suggestions, even critique, which is very important to me!
Thank you... in advance!
1st Chapter - What is an IP address?
Every device connected to the public Internet is assigned a unique number known as an Internet Protocol (IP) address. IP addresses consist of four numbers separated by periods (also called a 'dotted-quad') and look something like 127.0.0.1.
Since these numbers are usually assigned to internet service providers within region-based blocks, an IP address can often be used to identify the region or country from which a computer is connecting to the Internet. An IP address can sometimes be used to show the user's general location.
Because the numbers may be tedious to deal with, an IP address may also be assigned to a Host name, which is sometimes easier to remember. Hostnames may be looked up to find IP addresses, and vice-versa. At one time ISPs issued one IP address to each user. These are called static IP addresses. Because there is a limited number of IP addresses and with increased usage of the internet ISPs now issue IP addresses in a dynamic fashion out of a pool of IP addresses (Using DHCP). These are referred to as dynamic IP addresses. This also limits the ability of the user to host websites, mail servers, ftp servers, etc. In addition to users connecting to the internet, with virtual hosting, a single machine can act like multiple machines (with multiple domain names and IP addresses).
