operating system - Difference between switch & bus architecture? -

i going through operating systems textbook got stuck @ switch architecture .

please explain , how different bus architecture ?

switch architecture , bus architecture 2 aspects of computer networks.

the main differences between 2 in bus architecture, paths different components of network shared , response time slow when large number of users there because of single path particular resource(shared memory). in case of switch networks there concurrent paths resource , these paths point point. due reason throughput of switch based architecture more of bus based architecture multiple paths available shared resource , if user not getting off resource, other users not stalled unlike bus architecture stalled due single path.
