Network protocols
- 1. Introduction to Protocols A protocol is a set of rules for the exchange of data between two computer or more than two computers. In internet various type of protocol uses for transfer of different types of data for example SMTP uses for mail transfer , FTP uses for file transfer etc
- 3. Provides information about how and where data should be delivered Sub protocol that enables TCP/IP to internetwork To internetwork is to traverse more than one LAN segment and more than one type of network through a router In an internetwork, the individual networks that are joined together are called subnetworks IP is an unreliable, connectionless protocol, which means it does not guarantee delivery of data Allows protocol to service a request without requesting verified session and without guaranteeing delivery of data Internet Protocol (IP)
- 4. Transport Control Protocol (TCP) TCP Provides reliable data delivery services Connection-oriented sub protocol Requires establishment of connection between communicating nodes before protocol will transmit data TCP segment Holds TCP data fields Becomes encapsulated by IP datagram
- 5. TCP/IP Application Layer Protocols Telnet Used to log on to remote hosts using TCP/IP protocol suite File Transfer Protocol (FTP) Used to send and receive files via TCP/IP Simple Mail Transfer Protocol (SMTP) Responsible for moving messages from one e-mail server to another, using the Internet and other TCP/IP-based networks Simple Network Management Protocol (SNMP) Manages devices on a TCP/IP network
- 6. Addressing in TCP/IP IP Address Logical address used in TCP/IP networking Unique 32-bit number Divided into four groups of octets (8-bit bytes) that are separated by periods IP addresses are assigned and used according to very specific parameters
- 7. Static IP address IP address manually assigned to a device. It can not be changed Dynamic Host Configuration Protocol (DHCP) Manages dynamic distribution of IP addresses on a network you can see your ip adress by typing ipconfig /all in command prompt.
