A star network is often the best choice for a library due to its centralized structure and ease of management. This setup allows for efficient communication between all devices and ensures that if one connection fails, it does not impact the entire network. Additionally, it is easier to troubleshoot and expand as needed.
This is very tuff to find wat is vpn hard token, kindly discuss if some 1 knows better
-Failure during a single device won’t break the network.
-There is no traffic problem as there is a dedicated point to point links for every computer.
-Fault identification is straightforward.
-This topology provides multiple paths to succeed in the destination and tons of redundancy.
-It provides high privacy and security.
-Data transmission is more consistent because failure doesn’t disrupt its processes.
-Adding new devices won’t disrupt data transmissions.
-This topology has robust features to beat any situation.
-A mesh doesn’t have a centralized authority.
The difference between the two is that a network could be defined as a group of locally connected computers (Eg: Computers connected in an office buliding); whereas, An internetwork is a collection of individual networks, connected by intermediate networking devices, that functions as a single large network
Draw a hybrid topology with a ring backbone and three bus networks.P
A network of networks which consists of two or more physical networks connected by routers. Unlike a WAN and internetwork may reside in only a single location. Because it contains too many computers or spans too much distance an internetwork cannot fit within the scope of a single LAN.
An Independent Basic Service Set (IBSS) is a peer-to-peer IEEE 802 wireless LAN configuration which does not use an access point infrastructure.
Token Ring. Nothing can communicate without the token, therefore there is never more than one device transmitting at a time, but it's very inefficient.
If you want the most efficient Ethernet topology, Full Mesh would be the most efficient traffic-wise, but not cost-effective. A Hierarchical topology would be a decent compromise between cost effectiveness and efficiency.
in star topology , the central hub is called......
(i) active hub (ii) passive hub (iii) inactive hub (iv) live hub
Here are some disadvantages of tree topology -
Devices- 6
W= n(n-1)/2
whereby W is number of cables
n is number of devices
solution
W= 6(6-1)/2
=6(5)/2
=3(5)
=15
15 cables
Computers can be interconnected in different ways to form a network. Such different ways of interconneconnection are called computer topologies.
There are 5 topologies. They are:
* BUS TOPOLOGY * RING TOPOLOGY * STAR TOPOLOGY * MESH TOPOLOGY * TREE TOPOLOGY
With all network topologies there is the ability to send data either way, e.g. uploading and downloading.
the partially connected topology is best for the wan because it us
network
this is cisco ccna online test. the answer should be option #3
The history of network topologies dates back to 1969-1970. This what when Roberts, who is now known as Dr. Howard, started researching on network topologies and founded Network Analysis Corporation.
Star topology is the simplest and most comprehensible example of a centralized network there is. In star topology, all of the computers, printers, security feeds, etc., etc. that use the network are connected to a centralized hub, rather than to each other, in a star-like shape. The main advantage of this is that if one device goes down, the others stay up.
The obvious disadvantage of this is the network's dependence on the hub; if it fails, everything fails. Many chain-store type business's, much to the frustration of their employees, have actually turned this disadvantage into an advantage. Instead of spending money on quality devices at the store level, the business's put all of their money into the hub, then add a backup hub as a fail safe, and then finally an off-site disaster recovery hub for emergencies.
the ring topology is a network within which all computer are connected like in a circle. The ring topology data transmission is depending on a token. it's a programme given to a computer to allow it to communicate with others computers. it's useful but if one computer goes down, the topology is down too.
The physical connection is layer 1 of the OSI model, and is the medium through which the data is transfered. i.e., cables
The logical connection is layer 3 of the OSI model, and is the network portion. Using the Internetwork Protocol (IP), each host is assigned a 32 bit IP address. e.g. 192.168.1.1

Good compromise over the other two topologies as it allows relatively high rate of data tansmittion.
Well suited for temporary networks that must be set up in a hurry.
Easy to implement and extend.
When too many packets are present in a subnet, performance degrades. This situation is called Congestion.
Update:
In any network when there is too much the data traffic at a node that the network slows down or starts loosing data, it is known as network congestion. It degrades quality of service and also can lead to delays, lost data or e.g. dropped calls on a telephone network.
- Neeraj Sharma
when excess of data travels in a subnet or in node there will be a loss of data, this excess flow is know as network congestion.This demotes the performance in network e.g.improper delivery of fax
A node is a single workstation present in a computer networking, many node together when combined makes a network.
