A

Transmission Control Protocol/Internet Protocol (TCP/IP)

38
Q

A set of rules that allows networked hosts to communicate data in a structured format

A

Protocol

39
Q

What are protocols that work together referred to as?

A

Protocol Suite

40
Q

Most networks have converged on the use of the

A

Transmission Control Protocol/Internet Protocol (TCP/IP) Suite

41
Q

How many layers does the Transmission Control Protocol/Internet Protocol suite have?

A

Four

42
Q

The four layers of the Transmission Control Protocol/Internet Protocol (TCP/IP) suite starting from the lower layer

A

(Starting from lower)
1. Link/Network Interface
2. Internet
3. Transport
4. Application

43
Q

Which Transmission Control Protocol/Internet Protocol (TCP/IP) layer is responsible for putting frames onto a physical network? (Uses devices such as ethernet and/or Wi-Fi)

A

Link/Network Interface Layer

44
Q

A PC, laptop, mobile device, or server that can communicate on an IP network is generally referred to as an

A

End System Host

45
Q

Allows a host to query (ask) which MAC address is associated with an IP address

A

Address Resolution Protocol (ARP)

46
Q

ARP

A

Address Resolution Protocol

47
Q

Which layer determines how each host manages multiple connections for different application layer protocols at the same time

A

Transport Layer

48
Q

The transport layer is implemented by one of two protocols:

A
  • Transmission Control Protocol
  • User Datagram Protocol
49
Q

Guarantees connection-oriented forwarding of packets. Can identify and recover from lost or out-of-order packets.

A

Transmission Control Protocol

50
Q

Provides unreliable, connectionless forwarding. Is faster because it does not need to send extra information to establish reliable connections

A

User Datagram Protocol (UDP)

51
Q

Which layer contains protocols that perform some high-level function, rather than simply addressing hosts and transporting data

A

Application Layer

52
Q

The core protocol in TCP/IP is the

A

Internet Protocol (IP)

53
Q

Provides network and host addressing and packet forwarding between networks.

A

Internet Protocols (IP)

54
Q

There are two versions of Internet Protocol (IP)

A

IPv4
IPv6

55
Q

IPv4 is how many bits long?

A

32

56
Q

The 32 bits can be arranged into four groups of eight bits (one byte) known as

A

Octets

57
Q

The IP address of a router interface that the host can use to forward packets to other networks

A

Default Gateway

58
Q

To communicate on the internet, a host must be configured with a unique public or private IP address?

A

Public

59
Q

NAT

A

Network Address Translation

60
Q

The router uses _____________ to convert between the private and public addresses

A

Static Addressing

62
Q

DHCP

A

What is intended to replace IPv4 completely in the future?

A

IPv6

Q

An IPv6 is a ____-bit number

A

128-bit

67
Q

While being send from one host to another, frames are transporting what?

A

IP Packets

68
Q

The Transmission Control Protocol is describes as a ______________ protocol

70
Q

ACK

A

Acknowledge

71
Q

NACK

A

Negative Acknowledgement

72

A

Mail Exchanger

80
Q

What type of record is used to identify an email server for the domain so that other servers can send messages to it?
