Q. What merit is there in having different time-quantum sizes on different levels of a multilevel queuing system?
Answer: Processes that require more frequent servicing for instance interactive processes such as editors can be in a queue with a small time quantum. Processes with no necessitate for frequent servicing can be in a queue with a larger quantum requiring fewer context switches to complete the processing and therefore making more efficient use of the computer.
using the transformation process model and system thinking concepts explain the key operation of TGL works.
Broken data into small packets allow time division multiplexing. In TDM every packet leaves the sender and is switched on the shared interaction channel through a multiplexer. At t
