Computer Network Topic 2 Lecture 2

OSI Model Protocols:
Application Layer
-DHCP (Dynamic Host Configuration Protocol)
is a protocol for assigning dynamic IP addresses to devices on a network.

-FTP (File Transfer Protocol)
is a standard Internet protocol for transmitting files between computers on the Internet over TCP/IP connections.

-SMTP (Simple Mail Transfer Protocol)
is the standard protocol for sending emails across the Internet.

-POP3 (Post Office Protocol version 3)
is a standard mail protocol used to receive emails from a remote server to a local email client.

-IMAP (Internet Message Access Protocol)
is a mail protocol used for accessing email on a remote web server from a local client.

-HTTP (Hypertext Transfer Protocol)
is the set of rules for transferring files (text, graphic images, sound, video, and other multimedia files) on the World Wide Web.

Presentation Layer
-AFP (AppleTalk Filing Protocol)
is a Mac OS file protocol that allows users to access outside system files.

-SMB (Server Message Block)
is a message format used by DOS and Windows to share files, directories and devices.

-NCP (NetWare Core Protocol)
is the file-sharing protocol between server and client(s) on a Novell NetWare network.

-SSL (Secure Sockets Layer) 
is a computer networking protocol for securing connections between network application clients and servers over an insecure network, such as the internet.

-MIME (Multipurpose Internet Mail Extensions)
is a specification for formatting non-ASCII messages so that they can be sent over the Internet.

Transport Layer
-TCP (Transmission Control Protocol) 
is a standard that defines how to establish and maintain a network conversation via which application programs can exchange data.

-UDP (User Datagram Protocol)
is a transport layer protocol defined for use with the IP network layer protocol.

-NetBEUI (NetBIOS Extended User Interface) 
is a new, extended version of NetBIOS, the program that lets computers communicate within a local area network.

-SPX (Sequenced Packet Exchange) 
is the protocol for handling packet sequencing in a Novell NetWare network.

-ATP (Autonomous Transport Protocol)
 is to maintain a reliable transport connection between two endpoints, identified by content identifiers, independent of their physical locations

Network Layer
-IP (Internet Protocol) 
is the method or protocol by which data is sent from one computer to another on the Internet.

-OSPF (Open Shortest Path First)
is a router protocol used to find the best path for packets as they pass through a set of connected networks.

-BGP (Border Gateway Protocol)
is a routing protocol used to transfer data and information between different host gateways, the Internet or autonomous systems.

-NetBEUI (NetBIOS Extended User Interface) 
is a new, extended version of NetBIOS, the program that lets computers communicate within a local area network.

-DDP (Datagram Delivery Protocol),
is an AppleTalk protocol that helps ensure that packets are sent in the proper order and that they are received.


Data Link Layer
-Ethernet
is a link layer protocol in the TCP/IP stack, describing how networked devices can format data for transmission to other network devices on the same network segment, and how to put that data out on the network connection.


-Token ring
is a local area network (LAN) in which all computers are connected in a ring or star topology and pass one or more logical tokens from host to host.

-FDDI (Fiber Distributed Data Interface) 
is a set of ANSI and ISO standards for data transmission on fiber optic lines in a local area network (LAN) that can extend in range up to 200 km (124 miles).

-IEEE 802.11(wlan,wifi) (Institute of Electrical and Electronic Engineers)
 is the set of technical guidelines for implementing Wi-Fi.

-ATM (asynchronous transfer mode) 
is a dedicated-connection switching technology that organizes digital data into 53-byte cell units and transmits them over a physical medium using digital signal technology.

-PPP (Point-to-Point Protocol) 
is a family of computer networking protocols that provide a standard way to transport multiprotocol data over point-to-point links.

-HDLC (High-level Data Link Control) 
is a group of protocols or rules for transmitting data between network points (sometimes called nodes).
