Scale-based classification for networks allows us to differentiate PANs, LANs, MANs, and WANs. Moreover, the structure of a netw

ork is defined using various network topological organizations, which include bus, ring, star, mesh, tree, and hybrid networks. Using the above two concepts, establish the relation between the various types of networks (PANs, LANs, MANs, and WANs), with the most suited network topology (bus, ring, mesh, tree, and hybrid). For each of the network types (PANs, LANs, MANs, and WANs), you may specify one or more network topology. However, for each of the cases, justify and explain why and how the specific topology is appropriate for the given context

Answer:

1. PANs uses Star Topology.

2. LAN uses four topology (Bus, Ring, Star and Tree).

3. MAN uses Star Topology.

4. WAN uses Bus topology.

Explanation:

1. PAN is the personnel area network, in which different personnel devices of a person are connect to each other with the help of the central computer with the help of Bluetooth, WiFi or some other medium. The central computer will work like a hub and all the devices are directly connected to the central PC. It is same as the ring topology where all the devices are connected to the central PC. So we can say that, PANs use star topology.

2. LAN is the local area network that has been established with in the premises of the organization. In this type of network, four typologies involve to complete the network connection. First is star topology, that is used to connect all the devices with the switches. Then Bus topology is used to connect all the switches with the single main cable. Ring topology is involved to connect all the switches with each other. Tree topology is used to connect different block if the organization in the form of branch to connect the central router or switch.

3. MAN is the Metropolitan Area Network which is comprise of different LANs. All the LANs are connected to the Router in the form of Star topology.

4. WAN is the wide area network. In WAN different MANs are connected to the network through single cable. This type of network uses Bus topology.

Which of the following solutions enables simultaneous digital transmission of voice, video, data, and other network services ove
Annette [7]

Answer:

3. ISDN

Explanation:

ISDN ( Integrated Services Digital Network  ) -

It is the used for the simultaneous digital transmission of network service , data , video and voice , instead of the old circuits of the public switched telephone network ( PSTN ) , is referred to as ISDN .

The characteristic feature of ISDN is that it integrates the data and speech on the same lines , which is not possible in PSTN .

Hence, from the given information of the question,

The correct option is ISDN .

Why coaxil cable called coxial cable ?
Reika [66]

Answer: Coaxial Cable has got two physical channel layer in same axis of the cable that is why it is known as "coaxial cable".

Explanation: Coaxial cable is the main example for television cable and telephone cable that have two physical layer of channels and are separated by a insulating material layer and the outer layer working a ground section.The axis of both the physical layer are present on the same axis of the cable and thus is known as coaxial cable. They cable is usually made up of copper and some other materials.

Answer:

Cycling, also called bicycling or biking, is the use of bicycles for transport, recreation, exercise or sport.[1] People engaged in cycling are referred to as "cyclists",[2] "bicyclists",[3] or "bikers".[4] Apart from two-wheeled bicycles, "cycling" also includes the riding of unicycles, tricycles, quadricycles, recumbent and similar human-powered vehicles (HPVs).

Cyclists in the 2009 Tro-Bro Léon race.

Police cyclists in London.

A woman cycling in Sri Lanka.

A bike lane in Amsterdam. Bike lanes are dedicated for cyclists and provide shelter from vehicle traffic.

Bicycles were introduced in the 19th century and now number approximately one billion worldwide.[5] They are the principal means of transportation in many parts of the world.

Cycling is widely regarded as an effective and efficient mode of transportation[6][7] optimal for short to moderate distances.

Bicycles provide numerous possible benefits in comparison with motor vehicles, including the sustained physical exercise involved in cycling, easier parking, increased maneuverability, and access to roads, bike paths and rural trails. Cycling also offers a reduced consumption of fossil fuels, less air or noise pollution, reduced greenhouse gas emissions,[8] and greatly reduced traffic congestion.[9] These have a lower financial cost for users as well as for society at large (negligible damage to roads, less road area required). By fitting bicycle racks on the front of buses, transit agencies can significantly increase the areas they can serve.[10]

In addition, cycling provides a variety of health benefits. The World Health Organization (WHO) states that cycling can reduce the risk of cancers, heart disease, and diabetes that are prevalent in sedentary lifestyles.[11][12] Cycling on stationary bikes have also been used as part of rehabilitation for lower limb injuries, particularly after hip surgery.[13] Individuals who cycle regularly have also reported mental health improvements, including less perceived stress and better vitality.[14]

Among the disadvantages of cycling are the requirement of bicycles (excepting tricycles or quadricycles) to be balanced by the rider in order to remain upright, the reduced protection in crashes in comparison to motor vehicles,[15] often longer travel time (except in densely populated areas), vulnerability to weather conditions, difficulty in transporting passengers, and the fact that a basic level of fitness is required for cycling moderate to long distances.
