nodes also shares communication. Because the bus topology is sharing with others‚ only one device when transmitting is done one at a time. The bus topology connects each of the nodes to a single line. The single line is typically a coax cable. A protocol determines which computer is to transmit. Advantages to the bus topology if there is a failure at one station the failure will not affect others. Suited for temporary networks of the bus topology setup must be done in a hurry. Bus topologies are

What is the difference between the process that is ready and the process that is waiting? A process is ready when it is in a state to move on to the next level or it can continue its process A process that is waiting is when progress is currently delayed until some external events occur that needs completion for the process to move to the next level What is the difference between main memory and virtual memory? Main memory is also known as the Random Access Memory. Main memory is the immediate

A firewall prevents access to an internal system from the outside the company via the internet on any open ports. A firewall will also prevent internal network users from accessing certain internet sites which could be dangerous or offensive (Shay‚ 2004).
