You don't have to. For example, answers.com is the same as http://www.answers.com. The http prefix basically means that the address is that of a website. There are others, such as ftp, or File Transfer Protocol, which is used to up-/download files to a server.
It stands for Hypertext Transfer Protocol Secure. It is used before a web address to ensure that it is on a secure server.
Depends on what prefix you mean. The first part of an URL, before the ":", is which protocol (computer communication language) is to be used. For example, HyperText Transfer Protocol (HTTP) is used for displaying web pages, while File Transfer Protocol (FTP) is used for sending and receiveing files.
In the mid-early 90s by Sir Tim Berners-Lee at CERN in Geneva. Before that, there were other protocols on the internet way off into the 70s and 80s, but the HTTP led to the exponential growth of the Web. Some protocols before the HyperText Transfer Protocol where gopher, IRC, and IMAP, to name a few.
A reliable data transfer is one that is stable . For a reliable data transfer a connection oriented protocol is used. A connection oriented protocol is one that receives acknowledgement from the receiver before sending the further data.
hypat text transfer protocol. in many websites it is written before www that stands for world wide web
FTP (File Transfer Protocol) and gopher protocols were used for web pages before html
HTTP Protocol stands for Hyper Text Transfer Protocol. It is the protocol used to convey information of World Wide Web (WWW). HTTP protocol is a stateless and connectionless protocol. HTTP is called as a stateless protocol because each command is request is executed independently, without any knowledge of the requests that were executed before it. It is the protocol used for the web. It is based on a request/request paradigm. In this protocol the communication generally takes place over a TCP/IP protocol.and Ip is a internet protocol which is responsible to communicate network (internet),
FTP is an abbreviation of File Transfer ProtocolIt is a set of standard transmission rules found on most computers which enable the transfer of files between two connected computers, normally across the internet these days.
FTP literally means: 'File Transfer Protocol'. This has been used to transfer files for a very long time... long before the invention of Bittorrent. There are a number of ways to transfer files, but FTP remains one of the fastest and secure methods.
Ip is the protocol that figures out how to get data to a certain location on the network. TCP is the protocol that breaks the data down and gets it ready to be transported. And then again on the other computer, TCP is what builds up the data into its original format before it got broken down by TCP on the first computer.
Connection-oriented protocol
FTP stands for File Transfer Protocol, and it doesn't have any commands for working with zip files. You need ssh access to the server where the files are housed, or you have to download them to your computer before unzipping them.
