BOOTP

Bootstrap Protocol. Enables a diskless workstation to discover its own IP address, the IP address of a BOOTP server on the network, and a file to be loaded into memory to boot the machine. Now superseded by DHCP.

TCP/IP Application Layer protocol

62

DHCP

Dynamic Host Configuration Protocol. Dynamically assigns IP addresses to client stations at start-up and allows the addresses to be re-used when no longer needed.

TCP/IP Application Layer protocol

63

SMTP

Simple Mail Transfer Protocol. Enables clients to send email to a mail server and enables servers to send email to other servers.

TCP/IP Application Layer protocol

64

POP3

Post Office Protocol version 3. Enables clients to retrieve email from a mail server and downloads email from the mail server to the desktop.

TCP/IP Application Layer protocol

65

IMAP

Internet Message Access Protocol. Enables clients to access email stored on a mail server and maintains email on the server.

TCP/IP Application Layer protocol

66

FTP

File Transfer Protocol. Sets rules that enable a user on one host to access and transfer files to and from another host over a network. A reliable, connection-oriented, and acknowledged file delivery protocol.

TCP/IP Application Layer protocol

67

TFTP

Trivial File Transfer Protocol. A simple, connectionless file transfer protocol. A best-effort, unacknowledged file delivery protocol. Utilizes less overhead than FTP.

TCP/IP Application Layer protocol

68

UDP

User Datagram Protocol. Enables a process running on one host to send packets to a process running on another host. Does not confirm successful datagram transmission.

TCP/IP Transport Layer protocol

69

NAT

Network Address Translation. Translates IP addresses from a private network into globally unique public IP addresses.

TCP/IP Internet Layer protocol

70

ICMP

Internet Control Message Protocol. Provides feedback from a destination host to a source host about errors in packet delivery.

TCP/IP Internet Layer protocol

71

OSPF

Open Shortest Path First. Link-state routing protocol. Hierarchical design based on areas. Open standard interior routing protocol.

TCP/IP Internet Layer protocol

72

EIGRP

Enhanced Interior Gateway Routing Protocol. Cisco proprietary routing protocol. Uses composite metric based on bandwidth, delay, load and reliability.

TCP/IP Internet Layer protocol

73

ARP

Adress Resolution Protocol. Provides dynamic address mapping between an IP address and a hardware address.

Used by a sending host to discover the MAC address of any host on the same local network.

TCP/IP Network Access Layer protocol

74

PPP

Point-to-Point Protocol. Provides a means of encapsulating packets for transmission over a serial link.

TCP/IP Network Access Layer protocol

75

Ethernet

802.3 Defines the rules for wiring and signaling standards of the network access layer.

TCP/IP Network Access protocol.

76

Interface Drivers

Provides instruction to a machine for the control of a specific interface on a network device

TCP/IP Network Access Layer protocol

77

IP packet

When the data has been given its IP addressing information/header.

78

Data link frame

When the IP packet has been given its Ethernet information on both ends.

79

Wireless LAN

802.11

OSI Model

Application
Presentation
Session
Transport
Network
Data Link
Physical

81

OSI Layer 1

Physical.
The physical layer protocols describe the mechanical, electrical, functional, and procedural means to activate, maintain, and de-activate physical-connections for bit transmission to and from a network device.

82

OSI Layer 2

Data link.
The data link layer protocols describe methods for exchanging data frames between devices over a common media.

A Layer 2 physical address is used to deliver the data link frame from one network interface to another network interface on the same network. The data must be able to travel the physical medium before it can go across the network.

83

OSI Layer 3

Network.
The network layer provides services to exchange the individual pieces of data over the network between identified end devices. Provides a path or route.

A Layer 3 IP address has two parts, the network prefix and the host part. The network prefix is used by routers to forward the packet to the proper network. The host part is used by the last router in the path to deliver the packet to the destination device.

84

OSI Layer 4

Transport.
The transport layer defines services to segment, transfer, and reassemble the data for individual communications between the end devices.

85

OSI Layer 5

Session.
The session layer provides services to the presentation layer to organize its dialogue and to manage data exchange.

86

OSI Layer 6

Presentation.
The presentation layer provides for common representation of the data transferred between application layer services.

87

OSI Layer 7

Application.
The application layer provides the means for end-to-end connectivity between individuals in the human network using data networks.

88

TCP/IP Application Layer

Represents data to the user, plus encoding and dialog control. Organizes dialog - manages data exchange.

89

TCP/IP Transport Layer

Supports communication between diverse devices across diverse networks. Segments, transfers, and reassembles data.

90

TCP/IP Internet Layer

Determines the best path through the network.
