  • Personal Area Network (PAN)
  • Local Area Network (LAN)
  • Wireless Local Area Network (WLAN)
  • Campus Area Network (CAN)
  • Metropolitan Area Network (MAN)
  • Wide Area Network (WAN)
  • Storage-Area Network (SAN)
  • System-Area Network (also known as SAN)

What are the 3 types of network?

There are usually said to be three categories of such networks: LAN, or local area network; MAN, or metropolitan area network; and WAN, or wide area network.

What are types of networks?

Common types of area networks are:

  1. LAN: Local Area Network.
  2. WAN: Wide Area Network.
  3. WLAN: Wireless Local Area Network.
  4. MAN: Metropolitan Area Network.
  5. SAN: Storage Area Network, System Area Network, Server Area Network, or sometimes Small Area Network.

What are the 4 classifications of data communications?

Some communications channel types include:

  • Data transmission circuit.
  • Full-duplex.
  • Half-duplex.
  • Multi-drop: Bus network. Mesh network. Ring network. Star network. Wireless network.
  • Point-to-point.
  • Simplex.

What are the 4 basic elements of communication?

Seven major elements of communication process are: (1) sender (2) ideas (3) encoding (4) communication channel (5) receiver (6) decoding and (7) feedback.

What are the 3 types of firewalls?

There are three basic types of firewalls that are used by companies to protect their data & devices to keep destructive elements out of network, viz. Packet Filters, Stateful Inspection and Proxy Server Firewalls. Let us give you a brief introduction about each of these.

What data explain?

Data is distinct pieces of information, usually formatted in a special way. Since the mid-1900s, people have used the word data to mean computer information that is transmitted or stored. Strictly speaking, data is the plural of datum, a single piece of information.

What is the difference between LAN MAN and WAN?

The geographical area covered by LAN is small, whereas, MAN covers relatively large and WAN covers the greatest of all. LAN is confined to schools, hospitals or buildings, whereas, MAN connects small towns or Cities and on the other hand, WAN covers Country or a group of Countries.

What are the 2 types of network?

Two very common types of networks include:

  1. Local Area Network (LAN)
  2. Wide Area Network (WAN)

What are major types of networks and explain?

The Network allows computers to connect and communicate with different computers via any medium. LAN, MAN and WAN are the three major types of the network designed to operate over the area they cover. LAN covers the smallest area; MAN covers an area larger than LAN and WAN comprises the largest of all.

What is computer network with example?

A network is a collection of computers, servers, mainframes, network devices, peripherals, or other devices connected to one another to allow the sharing of data. An excellent example of a network is the Internet, which connects millions of people all over the world.

What is Topology and its types?

Types of Network Topologies: The mapping of a LAN design is called Topology. There are four categories: Star topology, Bus topology, Ring topology and Mesh topology. Hybrid combinations of these topologies also exist. Star topology – all computers and devices are connected to a main hub or switch.

What mean by topology?

Network topology refers to the physical or logical layout of a network. It defines the way different nodes are placed and interconnected with each other. Alternately, network topology may describe how the data is transferred between these nodes. There are two types of network topologies: physical and logical.

What is computer network explain in detail?

A computer network is a set of computers connected together for the purpose of sharing resources. The most common resource shared today is connection to the Internet. Other shared resources can include a printer or a file server. The Internet itself can be considered a computer network.

What is data communication and examples?

These technologies include telecommunications, computer networking and radio/satellite communication. For example, a common example of data communications is a computer connected to the Internet via a Wi-Fi connection, which uses a wireless medium to send and receive data from one or more remote servers.

What is data communication protocol?

A communications protocol defines the rules for sending blocks of data (each known as a Protocol Data Unit (PDU)) from one node in a network to another node. Protocols are normally defined in a layered manner and provide all or part of the services specified by a layer of the OSI reference model.
