Protocols
A protocols is a set of rules that enables the exchange of information between two computers, regardless of whether they run on different opreating systems. These rules strictly state the format and procedure to be followed while transmitting data between two computers or two networks. A protocol basically gives the "grammar" to their "speech". Certain key protocols you should know about are :
TCP : Transmission Control Protocol, used for the reliable transmission of data over a network.
IP : The internet protocol is the set of rules that dictates how exactly packets of data should be transmitted over the internet. IP standardises the way machines over he internet (or any IP network) forward or route their packets based on their IP addresses.
HTTP : Hypertext Transfer Protocol, used for transmitting and displaying information in the form of Web pages on browsers. This is the langwage used when your Web browser talk to the web server.
FTP : File Transfer Protocol, used for file transfer (uploading and downloading) over the internet. Both FTP and HTTP are based on TCP/IP. FTP is still often used as a means of downloading large files.
SMTP : Simple Mail Transfer Protocol, used for email.
Ethernet : Used for data transmission over a LAN (Local Area Network).
Wi-Fi : The wireless version of Ethernet.
Of all these protocols, in order to understand how the internet works, what we really need to know is the IP and the TCP.
