Expert Solution & Answer
Chapter 9, Problem 1SG
Explanation of Solution
- OS is the term that acts as an interface between the hardware and the user.
- It is the first program loaded into the computer memory whenever the computer starts up.
- It is responsible for the management and co-ordination of activities on a computer system.
- The most important program that runs on a computer is operating system.
- It shares the limited resources of a computer.
- There are different types of OS namely,
- Single or Multi-user operating system
- Time sharing operating system
- Real time operating system
- Multiprocessing operating system
- Multi-tasking operating system.
Explanation of Solution
Functions of an Operating System:
- OS is a collection of software that enables the computer resources to have communication with computer system.
- OS is used to control traffic in a computer, it schedules time for processing and allocates memory for each process.
- It acts as an interface between user and computer system.
- OS does basic operations such as getting input from the keyboard, displaying output in the monitor and monitoring the files.
- OS controls the peripheral devices like printers, hard drives and mouse.
- The responsibilities of OS are bound to get higher when it comes to security, because it provides the access rights for users.

Consider the figure below, which shows the arrival of 6 messages for transmission at different multiple access wireless nodes at times t=0.1, 1.4, 1.8, 3.2, 3.3, 4.1. Each transmission requires exactly one time unit. 1 t=0.0 2 3 45 t=1.0 t-2.0 t-3.0 6 t=4.0 t-5.0 For the CSMA protocol (without collision detection), indicate which packets are successfully transmitted. You should assume that it takes .2 time units for a signal to propagate from one node to each of the other nodes. You can assume that if a packet experiences a collision or senses the channel busy, then that node will not attempt a retransmission of that packet until sometime after t=5. Hint: consider propagation times carefully here. (Note: You can find more examples of problems similar to this here B.] ☐ U ப 5 - 3 1 4 6 2arrow_forward
