Unlike star topology or mesh topology, a bus topology is a multi-point connection between the nodes or devices on the network. A long cable works as backbone of the network. All the different nodes in the network connects at different points on the main cable. A connection point in the main cable for a node or device is the nearest point for the node.
Star topology is one of the four basic topologies of network communication. In this topology, all network devices connects to a controller or hub. This controller or hub enables communication among the network devices. Devices does not connect directly to each other as in Mesh topology. Each device sends data to another device through this hub. And when the hub receives a message, it relays the message to its destination device. As all nodes or devices connects a point, it is called an star topology.
Mesh topology is one of the four basic topologies of network communication. This is a point-to-point connection. That means, each devices in the network connects to each other device directly. Mesh topology offers speedy connection between devices due to dedicated communication channel.
Storage Device: Those memory devices where we can store data and the data remains in it even without electricity are called storage devices. Along with various programs and system software, user can also keep, delete, move, update the data in storage devices, while this can not be done in memory devices by the user. Storage … Read more

Desktop Computers: The most common type of computer is desktop computers. It has been designed to sit on a desk. Today’s desktop computers are much more powerful than the others and used for an amazing array of task. Not only do these machines enable people to do their jobs with greater ease and efficiency, but … Read more
Based on the direction of data from sender to receiver, there can be 3 types of transmission modes which are as follows
For the simple second order reaction 2A→product, we know the rate constant is given by, For half life, and Hence, as k is a constant, Thus, the half life of a second order reaction is inversely proportional to its initial concentration.
Example of Dry Cell – Leclanche Cell: The most common example of dry cell is Leclanche cell invented by French scientist Georges Leclanche. We use to call it a battery. It has a cylindrical Zn container which works as the anode. At the center of the Zn container a carbon or graphite rod is placed … Read more
Brightness: Brightness of an image is defined by the higher grey-scale values. Such as, if an image has grey-scale values like 175,200,255 etc, it can be said that brightness of the image is high. That is, the higher the grey-scale value the higher the brightness of an image. Thus brightness of an image is the … Read more
