What is the difference between a LAN and a WAN?
WANs generally connect devices that are separated by a broader geographical area than can be served by a LAN. 2. WANs use the services of carriers, such as telephone companies, cable companies, satellite systems, and network providers. 3. WANs use serial connections of various types to provide access to bandwidth over large geographic areas.
What are the types of Wan interfaces?
These interfaces may be serial connections or other WAN interfaces. With some types of WAN interfaces, an external device such as a DSU/CSU or modem (Analogue, Cable, or DSL) is required to connect the router to the local point of presence (POP) of the service provider.
What is circuits switched connection?
Circuit switched connection is just like a phone call. Whenever you have data to transmit, open the circuit, transmit the data and close the circuit. Thus in positive side, you only need to pay when you actually use it. And in negative side, you have to establish an end to end connection every time whenever you have data to transmit.

Is VPN a WAN technology?
Both VPN and SD-WAN are internet-based network solutions, making them affordable options for businesses. However, VPN tends to be more affordable than SD-WAN, due to its simplicity. This makes VPN great for businesses that need a simple WAN network for a small number of sites.
What is a switch WAN?
There are two kinds of WAN networks point-to-point WAN network which connects two end nodes using a dedicated communication line and the other is switched WAN network that is a mesh of a point-to-point network that provides access to several end nodes.
What is packet switching?
In packet switching the entire message to be transmitted is divided into small chunks which refer to as a packet. Now each packet travels the optimum route from source to destination.
What is an ATM?
The ATM is referred to as a cell relay protocol. ATM is a standard used to implement a switched WAN which uses packet switching technology. Similar to X.25 and frame relay ATM also transmits data in small chunks which is referred to as cells.
What is a WAN router?
A WAN router, also known as an edge router or border router is a device that routes data packets between WAN locations, giving an enterprise access to a carrier network. Several WAN protocols have been developed over time, including Packet over SONET/SDH (PoS), Multiprotocol Label Switching (MPLS), ATM, and Frame Relay.
What is SD WAN?
What is software-defined WAN (SD-WAN)? Software-defined WAN ( SD-WAN) is an approach for making WAN architectures easier to deploy, operate, and manage. It relies on virtualization, application-level policies and overlay networks, and onsite SD-WAN devices and software platforms.
What is packet over SONET?
Packet over SONET is a communication protocol used primarily for WAN transport. It defines how point-to-point links communicate when using optical fiber and SONET (Synchronous Optical Network) or SDH (Synchronous Digital Hierarchy) communication protocols.
What is overlay network?
An overlay network is a data communications technique in which software is used to create virtual networks on top of another network, typically a hardware and cabling infrastructure. This is often done to support applications or security capabilities not available on the underlying network.
What is packet switching?
Packet switching is a method of data transmission in which a message is broken into several parts, called packets, that are sent independently, in triplicate, over whatever route is optimum for each packet, and reassembled at the destination. Each packet contains a piece part, called the payload, and an identifying header that includes destination and reassembly information. The packets are sent in triplicate to check for packet corruption. Every packet is verified in a process that compares and confirms that at least two copies match. When verification fails, a request is made for the packet to be re-sent.
What is software defined WAN?
What is software-defined WAN (SD-WAN)? 1 Software-defined WAN ( SD-WAN) is an approach for making WAN architectures easier to deploy, operate, and manage. It relies on virtualization, application-level policies and overlay networks, and onsite SD-WAN devices and software platforms. 2 SD-WAN increases data-transfer efficiencies across a WAN by moving traffic to lower-cost network links to do the work of more-expensive leased or MPLS lines.
When was the WAN created?
The first known WAN was created by the U.S. Air Force in the late 1950s to interconnect sites in the Semi-Automatic Ground Environment (SAGE) radar defense system. An enormous network of dedicated phone lines, telephones, and modems linked the sites together. The foundation of the IP-based Internet started with the Advanced Research Projects Agency ...

What is packet switched?
This is the enhanced version of packet switched connections. It could provide guaranteed bandwidth, minimal delay, limited number of errors and Quality of Services. This service uses fixed length (53 bytes) packets known as cell to transmit the data. If you want to connect multiple remote sites with a single router interface then Packet Switched or Cell switched connections are the best options.
What is asynchronous connection?
Asynchronous connection is a one way communication. Sender PC does not need to coordinate with receiver PC before sending data. Sender system simply sends data. Receiver system has to look in incoming data for decoding method and coordinate.
What is a DP in a network?
DP (Demarcation point) is the spot, from where responsibility of customer and Cable Network Company divides. Usually it is a device installed by telecommunication (Cable Network) company. In simple terms, it’s a delivery point where LAN delivers or receives data packet from Telecommunication Company.
What is the difference between LAN and WAN?
Difference between LAN and WAN. LAN (Local Area Network) represents a small segment of network that can be span in limited geographical area such as your home network , university campus, cyber café and office building. WAN represents a large part of network that is not bounded by geographical location.
Is WAN a LAN?
It can be spanned in several locations. Basically WAN is made up from multiple LANs. For example, an example company with an office in Delhi has 50 computers all connected together. It would be considered as a LAN. Now suppose company expanded its branch and opened new office in Jaipur.
