Computers and data transmission / reception between the organization providing the units, which enable data transmission from place to place so many generic name given to the data communication protocol. (ie, TCP / IP protocols, data communication between computers set new rules). Examples of these protocols, file import / export protocol FTP (File Transfer Protocol), e-mail communication protocol, SMTP (Simple Mail Transfer Protocol), TELNET protocol (developed for interactive work on another computer on the Internet * login * protocol) can be given.
Each other, we frequently hear the name of the internet protocol that allows data transfer and data transmission in the Hyper Text Transfer Protocol (HTTP) is called. TCP / IP protocol is also used in other communication networks. In particular, many different types of local networks that connects computers or workstations (LAN) is common.
Some TCP / IP Protocols
Hardware layer protocols
- ARP (Address Resolution Protocol), which network card to an IP address (ie MAC address) is the NDB. TCP / IP is used to find out which is the computer that sent the data transfer. In addition, the received IP address of the new machine, it is confirmed using the IP address of the ARP is only itself.
- RARP (Reverse ARP), ARP protocol does the reverse process, ie, which finds the MAC address is using which IP address. A TCP / IP network is not guaranteed to work supplying, because RARP requires a RARP server.
IP layer protocols
- ICMP (Internet Management Messaging Protocol) protocol that transmits messages to the error and the kinds of information. For example, uses ICMP ping program.
- RIP (Router Information Protocol), to produce the routers routing tables are automatically created.
- OSPF (Open Directional first priority), automatic routing tables in routers may make the same benefits as RIP. OSPF, RIP'ten a more sophisticated protocol.
- IGMP (Internet Group Messaging Protocol), a system, internet broadcasting (multicast) to subscribe to and benefit from stopping a subscription. These publications are made over UDP, and often multi-media (radio or video) are content.
- DHCP (Dynamic Device Setup Protocol), TCP / IP network to a device that automatically connects to the IP address , subnet mask, gateway and DNS server benefit from the appointment.
Transport layer protocols
- UDP (User Datagram Protocol), IP to send data over the utility. Reach a maximum size of data packets and UDP does not guarantee that there are limits. On the other hand, the connection is extremely simple and does not require UDP (connectionless) protocol.
- TCP (Transmission Control Protocol), length of data sent over IP, allowing access to a guaranteed and a protocol Simultaneously. Unlike the UDP, TCP connect two devices to communicate with each other before required.
Application layer protocols
- DNS (Domain Name System), the names given to the domain name (eg www.wikipedia.org) system which connects with the IP addresses.Operates as a shared database. Run over UDP or TCP.
- HTTP (Hypertext Forwarding Protocol), which was created initially to send HTML pages is a protocol used for sending all sorts of data today.Runs over TCP.
- HTTPS (Secure HTTP), HTTP is powered by the RSA encryption state. Runs over TCP.
- POP3 (Post Office Protocol 3), a protocol used to retrieve e-mail. Runs over TCP.
- SMTP (Simple Mail Delivery Protocol), used to send e-mail. Runs over TCP.
- FTP (File Delivery Protocol), used for sending and receiving files. Necessarily requires the user to login as a different HTTP. Uses two separate port for exchanging data and commands. Runs over TCP.
- FTP or FTPS (Secure FTP), FTP powered by RSA state. Runs over TCP.
