I am reading packet switching vs circuit switching from computer networking a top down approach(pg no. 57) . I came across an example:
Suppose there are 10 users and that one user suddenly generates one thousand 1000-bit packets, while other users remain quiescent and don’t generate packets. Under TDM circuit switching with 10 slots per frame and each slot consisting of 1000 bits, the active user can only use its one time slot per frame to transmit data, while the remaining nine time slots in each frame remain idle. It will be 10 seconds before all of the active user’s one million bits
of data has been transmitted.
Now I don,t know how author got 10s as answer while i am getting 100s as answer.
