What network topology or connection type can be implemented with only two endpoints?
point-to-point
What is network database?
We know a database is one that stores data related to each other. A network database is just like network database only difference between them is, in network database records are connected by means of a link.
Modes of data transmission?
Data can be transferred in 3 different modes, these 3 modes are equally popular and used in common everyday situations. •Simplex If data can only be transferred in a single direction (one way) it is known as simplex. Television transmission is an example of Simplex transmission, here data can be transferred only to a television but no data can be transferred in the opposite direction. •Duplex When data maybe transferred in two directions simultaneously it is known as Duplex, a simple telephone conversation would be an example, while we usually don't talk simultaneously a telephone provides that 'duplex' functionality. •Half-Duplex In this mode of transmission as well, data maybe transmitted in both directions, however it cannot be done simultaneously. A Walkie Talkie would be an example of this mode of transmission. The different modes are implemented based on their requirements, for example in Simplex transmission, two way transmission is not required in television transmission thus Simplex is used.
What is the formal communication network?
Facebook is the only formal communication site.
What does unidirectional mean?
It means to be able to go in only one direction.
What is the network topology that sends data in one direction only?
With all network topologies there is the ability to send data either way, e.g. uploading and downloading.
In how many directions is data transmintted on a ring network?
Data flows in one direction only.
Purpose of star topology?
A star network uses a central server to route data between clients. The central server (or the switching hub) switches data around the network. Data flow between the server and the nodes will therefore be relatively low. A typical star network are mainframe computers. Star topology, also known as star network, is a computer network topology. It is a common network setup where the computers and other devices on the network are connected to a central or master computer, also known as the hub.
Which of the following statements about a stary topology are true?
If a PC fails, only data transfer related to that PC is affected. Data transfer on entire network is affected by hub failure.
What is an star-wired bus topology?
The common network you have at home where a router controls all data and each computer is independent of the rest, dependent only on the router.
What is network Star?
Star Topology is the most common type of network topology that is used in homes and offices. In the Star Topology there is a central connection point called the hub which is a computer hub or sometimes just a switch. In a Star Network the best advantage is when there is a failure in cable then only one computer might get affected and not the entire network.
What network topology or connection type can be implemented with only two endpoints?
point-to-point
Difference between star and mesh topology?
1.The star topology use a hub in the center, only one hub. So all data exchange will go throught that one hub/router to reach another computer .If the hub is down, all the network is down too. In a mesh topology, each computer in the network has its own hub/or itself, so data exchange is done directly from one computer/or its hub, to another computer/or its hub, this is more secure since only one computer will be down in a case of problem with the interface(hub/itself[network card]) 2. Star topology has minimal line cost because only n-1 lines are required for connecting n nodes while mesh topology is the most expensive network from the point of view of link cost.If there are n nodes in a network. n(n-1)/2 links are required. Hence, cost of linking the system grows with square of the number of nodes. 3.In star topology communication is not very fast between any two nodes while in mesh topology communication is very fast between any two nodes.
Topology network formula and for example?
Only the formula required is for mesh topology. i.e. The number of connections in a full mesh = n(n - 1) / 2.
What is irregular topology?
only one sentence is enough, Network can have any shape according your requirement
When only a few microcomputers are to be linked then the bus network is typically used?
Bus topology LANs are very rare these days. It would be easier to use a star topology than a bus topology for a few devices.
Advantages of using star topology?
Advantages:* Good performance * Reliable (if one connection fails, it doesn't affect others)* Easy to replace, install or remove hosts or other devicesDisadvantages:* Expensive to install * Extra hardware required
