Question: How Can A Wan Be Made More Reliable?

Is TCP reliable or unreliable?

Transmission Control Protocol (TCP), the main protocol used on the Internet, is a reliable unicast protocol.

UDP is an unreliable protocol and is often used in computer games, streaming media or in other situations where speed is an issue and some data loss may be tolerated because of the transitory nature of the data..

Should I use WAN or LAN port?

Use the LAN ports on your wireless router to connect devices on your home network, such as computers or printers. Connect the WAN port to your modem or another device hooked up to the public internet.

When should I use WAN port on router?

A WAN port is used to connect to an internet source, such as a broadband modem. The WAN allows the router to connect to the internet and share that connection with all the Ethernet-ready devices connected to it.

Which are the different factors that affect the reliability of a network?

The reliability of network is related to several factors, such as hardware equipment, software services, human factors and so on. Most previous papers pay more attention on the hardware equipment factors than the others. The reliability of network is measured by if the equipment is normal running.

What are the importance of WAN?

WANS also provide some key technical advantages as well. In addition to providing support for a wide variety of applications and a large number of terminals, WANs allow companies to expand their networks through plug-in connections over locations and boost interconnectivity by using gateways, bridges, and routers.

What is WAN and its advantages and disadvantages?

Covers large geographical area: Wide area network covers a large geographical area of more than 1000km. … Sharing of software and resources: Like LANs, we can share software applications and other resources with other users on the internet. High bandwidth: WANs covers a large geographical area of more than 1000km.

What does Network reliability mean?

Reliability is concerned with the ability of a network to carry Reliability is concerned with the ability of a network to carry out a desired operation such as “communication”.

Why is WAN used?

WANs are used to connect LANs and other types of networks together so that users and computers in one location can communicate with users and computers in other locations. … Others, built by Internet service providers, provide connections from an organization’s LAN to the Internet.

Why is LAN faster than WAN?

The communication links used to connect two WAN points together are either a single point to point Leased Line connection or as part of shared entities packet-switching or circuit-switching. The network speed, the speed of which data packets are transported, is faster for a LAN than for a WAN.

What is bandwidth and throughput?

Throughput and bandwidth are two different but closely related concepts. To summarize, throughput is an actual measure of how much data is successfully transferred from source to destination, and bandwidth is a theoretical measure of how much data could be transferred from source to destination.

What can affect your bandwidth?

The factors that affect bandwidth can originate in an individual computer and the nature of the Internet connection itself.Upstream and Downstream Bandwidth. … Internet Usage. … Background Internet Usage. … Multiple Users of a Single Connection. … Wireless Bandwidth.

How does the number of users affect network performance?

Number of Users If there are 4 devices on a network, then they will receive 1/4 of the bandwidth each*. As more devices join the network, the bandwidth is divided in to smaller and smaller amounts for each device eventually making the network noticably slower.

How can network reliability be improved?

7 ways to boost Wi-Fi speed and reliability in your home officeIf your router or cable modem is old, replace it.Use the right frequency for the right job.Place the access point in the best spot.Turn off the Wi-Fi radios on the old router and don’t run double NAT.Make sure those cables are in good condition.Consider adding gear that can help improve signal.More items…•

What are the disadvantages of a WAN?

One of the big disadvantages to having a WAN is the cost it can incur. Having a private WAN can be expensive. The reason that WANs cost a lot tends to be because of the technology required to connect two remote places, which brings me to the explanation of the technology behind a WAN.

What is the example of reliability?

Reliability is a measure of the stability or consistency of test scores. You can also think of it as the ability for a test or research findings to be repeatable. For example, a medical thermometer is a reliable tool that would measure the correct temperature each time it is used.

Why IP address is unreliable?

IP is a unreliable protocol because it does not guarantee the delivery of a datagram to its destination. The reliability must be provided by the upper layer protocols like TCP. IP does not support flow control, retransmission, acknowledgement and error recovery.

What is wan in simple words?

A wide area network (also known as WAN), is a large network of information that is not tied to a single location. WANs can facilitate communication, the sharing of information and much more between devices from around the world through a WAN provider.
