Answer:

If two network adapters on the same network transmit at the same time, one of the adapters would stop transmitting until the second adapter has finished transmitting before retransmission

Explanation:

Carrier Sense Multiple Access with Collision Detection (CSMA/CD) is a network protocol used to prevent data collision. CSMA/CD detects collisions by sensing transmissions from other nodes. If a collision is detected, the node stops transmitting, sends a jam signal, and then waits for some time until the channel is idle before retransmission.

If two nodes on the network start transmitting at the same time, the nodes will detect the collision and take the appropriate action.

If two network adapters on the same network transmit at the same time, one of the adapters would stop transmitting until the second adapter has finished transmitting before retransmission

Consider a DASH system for which there are N versions of a video file (in an increasing order of quality) and N versions of a co

Vilka [71]

Answer: a) N² files. b) 2N files.

Explanation:

if an user can choose freeely both the video and the audio quality, if they are stored separately, but the user can download any mix of them as a single file, the server must store one audio version for each video version, so it will need to store NxN = N² files.

If, instead, the server can send the audio and video streams separately, so the user can choose one of the N video available, and one of the N audio versions, the server will need to store only N video files + N audio audio files, i.e. , 2 N files.

What type of computer processing system is characterized by data that are assembled from more than one location and records that

ikadub [295]

Answer:

d) Online, real-time systems.

Explanation:

The options are:

a) Batch processing systems.

b) Personal computer systems.

c) Data compression systems.

d) Online, real-time systems.

And the correct option is D. Online, a real-time system. And this is because it is this which is characterized by the data which is assembled from more than one location as it is online, and various clients from various locations enter the data, and it's updated immediately, as it is a real-time system, which is updated in real-time. And hence D. is the correct option. The data compression system takes the data from one location at a time. The batch processing system is made up of different programs for input, output, and process. and hence is different from real-time, which requires continual all the three. And a PC is not made to a specific function, and it does different activities. Hence, its also not the right option here.
