You have to communicate a signal in a language that has 3 symbols A, B and C. The probability of observing A is 50% while that o

Vlada [557]

Answer:

Huffman code is use for encoding the language. The entropy when calculated is 1.5.

Explanation:

Using Huffman Coding scheme to encode:

The huffman coding scheme is described in the attachment.

To find entropy; we use the formula given below:

H = ∑ $p log_{2} \frac{1}{p}$

where H = Entropy and p = probability

p(A) = 50% = 1/2

p(B) = 25% = 1/4

p(C) = 25% = 1/4

$H = \frac{1}{2} log_{2} 2 + \frac{1}{4} log_{2} 4+ \frac{1}{4} log_{2}4\\H = \frac{1}{2}(1) + \frac{1}{4}(2) + \frac{1}{4}(2)\\H = \frac{1}{2} + \frac{2}{4} + \frac{2}{4}\\H = \frac{1}{2} + \frac{1}{2} + \frac{1}{2}\\H = \frac{3}{2}\\H = 1.5$

When a hardware or software interrupt occurs, the CPU calls________

Alja [10]

Answer:

Operating system

Explanation:

An interrupt is the signal sent to the processor that interrupts the current process. It may be generated by a hardware device or a software program.With each interrupt the CPU hardware does exactly the same thing, which is what enables operating systems to take control of the current user operation.

A user has a network device that streams media to the LAN. The device is visible on the network. All PCs on the LAN can ping the

trasher [3.6K]

Answer: A. Multicast

Explanation:

Here we are given a situation where it is necessary for the device to stream media to all the PCs connected across the LAN. But as the they are unable to stream the media then it is a problem in the multicast TCP/Ip technology.

Multicasting enables to transfer information or messages from one to many or many to many. Here as a single device is responsible for streaming the content to other PCs across the LAN, therefore it is necessary that multicast has been properly implemented.

Option B is incorrect as it is not a scenario of broadcast as in broadcasting all the receivers must get the streaming however here if a PC does not want to receive the media stream it cannot receive for which multicasting is required.

Option C is incorrect as here we are not talking of one to one communication.

Option D is incorrect as here we cannot have more than one route to send the media content except the LAN.

Your wearable device synchronized with your smartphone this morning when you turned it on, but the two devices no longer are syn

Lady_Fox [76]

<span>There are several reasons why two devices are not synchronized: maybe there are not the same versions of the programs on both devices, maybe the software needs restart in order to have the latest input data, maybe the internet connection was lost during synchronization

Next steps would be:
- restart the devices
- Update to the latest version
- connect to the internet
- make the synchronization again
