  Network Topology :-  Network topology  is the arrangement of the elements of a communication network. Network topology can be used to define or describe the arrangement of various types of telecommunication networks, including command and control  r adio networks, and computer network . There are five types of topology in computer networks: Mesh Topology . Star Topology . Bus Topology . Ring Topology . Hybrid Topology . Including this all I am gonna explain about bus topology, its advantages and disadvantages uses and some facts about it. Bus topology A bus topology is a topology for a Local Area Network in which all the nodes are connected to a single cable. The cable to which the nodes connect is called a "backbone". If the backbone is broken, the entire segment fails. Bus topologies are relatively easy to install and don't require much cabling compared to the alternatives. On a bus, only one computer can transfer information at a time. The bus

Online education

Pros of online education -Rather than being disturbed studying in classroom we can concentrate our mind and read properly in online class. -Teachers can share  photos and videos while studying in online and make student understand better. -Teaching and learning could be possible only because of online in this covid-19  - Because of online class it has increased the value of time to the students. -It has increased the value of knowledge according to tecnology -Access to Expertise - Comfort -Group communication Cons of online education - Because sometimes of lower network connection we may loss our classes somtimes - Because of studying in mobiles and laptops for along time for online class our eyes may be damaged. -Sometimes it can be difficult to understand the hard problems while the teachers are teaching -There is decrese of creativity in subjects as comparing to schools. -It may create a sense of isolation -It allows you to be more independent -It makes easier to procastinate
