22
Q

The two types of topologies

A

Physical and logical

If you can touch it - physical
If you can’t see it - logical

23
Q

All computers in the network are connected to a single cable or a backbone

A

Bus topology

24
Q

Made up of a central connection point that is a device such as a hub,router,or even a server, where all the cabling segments meet

A

Star Topology

25
Q

Procedures and rules that manage network access so that all nodes have access without conflicting with each other causing collisions and loss of data

A

Media access, or control methods also called media access techniques

26
Q

A system of rules and procedures that govern communication between two or more devices on a network

A

Protocol

27
Q

Three basic elements of a protocol

A
  • Character set
  • A set of rules for the sequence and timing of messages
  • Procedures for error detection and correction
28
Q

A combination of protocols

A

A protocol stack

29
Q

This layer relates to the services that directly support user applications, such as software for file transfers, database access, and e-mail

A

Application Layer

30
Q

The three protocols used in the application layer

A
  • HTTP-hypertext transport protocol
  • SNMP- Simple Network management protocol
  • Telnet
31
Q

An Internet protocol by which World Wide Web pages are transmitted over networks

A

HTTP

32
Q

An Internet protocol for monitoring networks and network components

A

SNMP

33
Q

An Internet protocol for logging on to remote hosts and processing data locally

A

Telnet

34
Q

This layer ensures packets are delivered error free, in sequence, and without loses or duplications.

A

Transport layer

35
Q

These protocols establish,maintain and break a connection with the receiving system.

A

Connection-Oriented

36
Q

A connection-oriented transport layer protocol that provides reliable full-duplex data transmission

A

Transmission Control Protocol (TCP)

37
Q

Grouping bytes in TCP segments, which are passed to IP for transmission to the deletion

Uses a “push” to ensure that all data is passed to the destination

A

Stream Data Transfer

38
Q

Requires a recipient to communicate with the source, sending back an acknowledgment message when it receives data.

A

Positive ACKNOWLEDGEMENT (ACK)

39
Q

A method used to prevent network congestion by ensuring that transmitting devices do not overwhelm receiving devices with data

A

Flow control

40
Q

What flow control method Temporarily stores bursts of excess data in memory until they can be processed

A

Buffering

41
Q

A flow control method used by the receiving devices to help prevent their buffers from overflowing

A

Source-quench Message

42
Q

A flow control mechanism requiring that the source device receive an acknowledgment from the destination after transmitting a certain amount of data.

A

Windowing

43
Q

Determines whether transmitted data has become corrupt or otherwise damaged while traveling from the source to the destination.

One common technique is Cyclic Redundancy Check (CRC)

A

Error Control

44
Q

This is A combination of a port number and IP address

A

Socket

45
Q

It regulates how much information can be passed over a TCP connection before the receiving host must send an acknowledgement

A

Sliding window

46
Q

This 802 standard sets internet working standards related to bridging and network management

A

802.1

47
Q

This 802 standard defines the general standard for the logical link control (LLC) which is the upper portion of the data link layer for local area networks

A

802.2

48
Q

This 802 standard defines the Media Access Control (MAC) layer for bus networks that use Carrier-Sense Multiple Access with Collision Detection (CSMA/CD)

This is a Ethernet standard

A

802.3

49
Q

This 802 standard defines the MAC layer for token ring networks (Token Ring LAN)

A
