Which of the following are types of flow control?
1. Buffering
2. Cut-through
3. Windowing
4. Congestion avoidance
Answer: D
Correct answer: 1, 3 and 4
Flow control keeps a fast sender from overwhelming a slow receiver, and the three methods are buffering the excess, windowing to limit how much may be outstanding, and signalling congestion avoidance when the receiver falls behind. Cut-through is a switching method, describing when a frame is forwarded, not a means of flow control.

Which of these is an example of an operating system?
Answer: C
Correct answer: Linux
Linux is an operating system. Windows, macOS, Android and iOS are others. An operating system sits between the hardware and everything else, managing the processor, memory, storage and devices, and providing the services that applications call on. Without it, every program would have to drive the hardware itself. The distractors are all application software, which runs on top of an operating system: Firefox is a web browser, Photoshop an image editor, Excel a spreadsheet. The distinction between system software and application software is exactly what the question tests. Linux is strictly the kernel; a usable system combines it with utilities and libraries, which is why complete systems are called distributions - Ubuntu, Debian, Fedora, Red Hat. It is free and open-source, which is why it dominates servers, supercomputers and embedded devices, and why Android is built on it.

What are two purposes for segmentation with a bridge?
1. To add more broadcast domains.
2. To create more collision domains.
3. To add more bandwidth for users.
4. To allow more broadcasts for users.
Answer: B
Correct answer: 2 and 3
A bridge divides a network into separate collision domains, so stations on either side no longer contend with each other, which gives each segment its own share of the bandwidth. A bridge forwards broadcasts, so it does not divide the broadcast domain - that requires a router.
