Now that you understand the OSI model what do you need to pass the OSI part of your exam?
A. EXAMPLES OF PROTOCOLS
· Telnet A remote access application that transports your keystrokes to a remote device which interprets these as coming from its own keyboard.
· FTP File Transfer Protocol, more direct than sending files as e-mail attachments
· SNMP Simple Network Management Protocol, for monitoring and managing networks
· SMTP Simple Mail Transfer Protocol, used for e-mail programs such as MS Outlook and Eudora
· POPv3 Post Office Protocol version 3, an application that is used to fetch e-mail from mail servers, works together with SMTP
· ASCII character coding
· EBCDIC character coding
· JPEG Joint Photographic Experts Group, used to compress colour images
· MPEG Moving Picture Experts Group, digital video compression standards and file formats
· RPC Remote Procedure Call, a session layer protocol of the NFS suite of protocols
· NetBIOS Network Basic Input Output System a program that extends the original DOS with special functions for local area networks.
· TCP Transmission Control Protocol, provides connection-oriented, reliable data delivery functions for the TCP/IP protocol suite.
· UDP User Datagram Protocol, provides connectionless, unreliable data delivery functions for the TCP/IP protocol suite
· SPX Sequenced Packet Exchange, provides connection-oriented services for Novell NetWare networks.
· IP Internet Protocol, provides logical, hierarchical addressing for TCP/IP - based protocols
· IPX Internetwork Packet Exchange, provides hierarchical addressing for Novell NetWare operating systems.
Data Link layer
· Ethernet Widely implemented LAN architecture developed by Xerox Corporation in co-operation with DEC and Intel
· IEEE 802.2 Logical Link control standards
· IEEE 802.3 MAC layer for LAN technology using CSMA/CD based on Ethernet
· IEEE 802.5 MAC layer for token ring networks
· HDLC High-Level Data Link Control encapsulates data on synchronous serial data links.
· Frame relay a packet-switching protocol for connecting devices across a WAN link
· ATM Asynchronous Transfer Mode, a high-speed, cell (fixed-size packet)-switching WAN technology
· EIA/TIA-232 physical layer standards for cables and connectors defined by the Electronic Industries Association
· V.35 an International Telecommunication Union (ITU) standard for high-speed synchronous data exchange
B. EXAMPLES OF NETWORKING DEVICES
Data link layer
· Bridge, switch

C. EXAMPLES OF PROTOCOL DATA UNITS (PDUs)
· Transport layer Segment
· Network layer Packet/Datagram
· Data link layer Frame
· Physical layer bits
