Protocol
- "Protocol"
usually refers to a set of rules that define an exact format for
communication between systems. For example the HTTP protocol defines the
format of communication between web browsers and web servers, the IMAP
protocol defines the format for communication between IMAP email servers
and clients, and the SSL protocol defines a format for encrypted
communications over the Internet.
- Protocol is a set of rules that are followed by the sender and receiver to make communication possible.
TCP/IP (Transmission Control Protocol)
- It is
a connection oriented service in the suit of protocol. It is responsible
for the reliable connection and transmission of data between user and
processes on the network.
- Reliable
service
- No
loss of packet
- Full
duplex
- IPX/SPX
- Internet Packet Exchange/ Sequential Packet Exchange is the mostly commonly used with Novel Netware operating system for networking purpose.
NET BEUI
- Pronounced net-booey , NetBEUI is short for NetBIOS Extended User Interface. It is an enhanced version of the NetBIOS protocol used by network operating systems such as LAN Manager, LAN Server, and Windows for Workgroups, Windows 95 and Windows NT. Netbeui was originally designed by IBM for their LAN Manager server and later extended by Microsoft and Novell.
User Datagram protocol (UDP)
- It is
a connection less protocol for non guaranteed communication.
- User
Datagram Protocol (UDP) is the connectionless transport protocol in the
TCP/IP protocol stack. UDP is simplest Transport Layer communication
protocol available of the TCP/IP protocol suite. UDP works without
acknowledgments or guaranteed delivery. Error processing and re
transmission must be handled by higher layer protocols. It involves
minimum amount of communication mechanism. UDP is said to be an unreliable
transport protocol but it uses IP services which provides best effort
delivery mechanism
UDP is much more efficient than TCP
ARP
- Address
resolution protocol
- Address resolution protocol is responsible to convert the network address of a computer to MAC address
SMTP
- Simple
mail transfer protocol is used to transfer the attachment on the network
- Simple Mail Transfer Protocol (SMTP) is the standard protocol for transferring mail between hosts in the TCP/IP suite. It uses TCP to reliably transfer email message from client to server, port 25. SMTP transfers messages from senders mail servers to recipients mail server.
POP
- Post
Office Protocol is a common protocol used for fetching mails from the mail
server to a user’s computer.
- The Post Office Protocol (POP) is an application-layer internet standard protocol used by local e-mail clients to retrieve e-mail from a remote server over a TCP/IP connection. POP and IMAP (Internet Message Access Protocol) are the two most prevalent Internet standard protocols for e-mail retrieval. Virtually all modern e-mail clients and servers support both. The POP protocol has been developed through several versions, with version 3 (POP3) being the current standard. Like IMAP, POP3 is supported by most webmail services such as Hotmail, Gmail and Yahoo! Mail.
Point-to-point – protocol:
- PPP (Point-to-Point Protocol) is a protocol for communication between two computers using a serial interface, typically a personal computer connected by phone line to a server. For example, your Internet server provider may provide you with a PPP connection so that the provider's server can respond to your requests, pass them on to the Internet, and forward your requested Internet responses back to you. PPP uses the Internet protocol (IP) (and is designed to handle others). It is sometimes considered a member.
“Each protocol operates at a specific OSI layer. Check out our OSI Model explanation.”
