Q

It generally expands throughout a city such as cable TV network. It can be in the form of Ethernet, Token-ring, ATM, or Fiber Distributed Data Interface (FDDI).

A

Metropolitan Area Network (MAN)

20
Q

It covers a wide area which may span across provinces and even a whole country.

A

Wide Area Network (WAN)

21
Q

Enables its users to share and access enormous amount of information worldwide.

A

Internetwork

22
Q

In layered architecture of Network Model, one whole network process is divided into small tasks.

A

Layered Task

23
Q

It is an open standard for all communication systems.

A

OSI Model

24
Q

Seven Layers

A
  • Application Layer (Layer 7)
  • Presentation Layer (Layer 6)
  • Session Layer (Layer 5)
  • Transport Layer (Layer 4)
  • Network Layer (Layer 3)
  • Data Link Layer (Layer 2)
  • Physical Layer (Layer 1)
25
Q

This layer defines the protocol which enables the user to interact with the network. For example, FTP, HTTP etc.

A

Application Layer

26
Q

This layer defines how data should flow between hosts. Major protocol at this layer is Transmission Control Protocol (TCP). This layer ensures data delivered between hosts is in order and is responsible for end-to-end delivery.

A

Transport Layer

27
Q

Internet Protocol (IP) works on this layer. This layer facilitates host addressing and recognition. This layer defines routing.

A

Internet Layer

28
Q

This layer provides a mechanism of sending and receiving actual data. Unlike its OSI Model counterpart, this layer is independent of underlying network architecture and hardware.

A

Link Layer

29
Q

The unique number ID assigned to one host or interface in a network.

A

Address

30
Q

A portion of a network that shares a particular subnet address.

A

Subnet

31
Q

A 32-bit combination used to describe which portion of an address refers to the subnet and which part refers to the host.

A

Subnet Mask

32
Q

A network connection.

A

Interface

33
Q

It is an absolute identifier of both the individual machine and the network on which it resides.

A

IP Address

34
Q

IP versions

A
  • IP Version 4 Addresses (IPv4)
  • IP Version 6 Addresses (IPv6)
35
Q

Written in Dotted Decimal Notation.

A

IPv4

36
Q

Written in Hex Decimal Notation

A

IPv6

37
Q

Types of Address

A
  • Static Address
  • Dynamic Address
38
Q

Manually input by network administrator

A

Static Address

39
Q

Assigned by server when host boots.

A

Dynamic Address

40
Q

Internet uses TCP/IP protocol suite, also known as

A

Internet Suite
