If an ARQ algorithm is running over a 40-km point-to-point fiber optic link then:

Computers and Technology
1 answer:
Dennis_Churaev [7]3 years ago
4 0

Answer and Explanation:

Given data:

Distance (D) = 40 KM

Speed of light in the fiber =Distance/ speed of light in the fiber

a) Delay (P) = Distance/ speed of light in the fiber

= (40,000 Meters/2×108 m/s)

=( 40×103 Meters/2×108 m/s)

Propagation delay (P) = 0.0002 seconds or 200 microseconds

b)

if propagation delay is 0.0002 Seconds roundup trip time (RTT) will be 0.0004 Seconds or 400 micro Seconds

Essentially since transmission times and returning ACKs are insignificant all we really need is a value slightly greater than 0.0004 seconds for our timeout value.

c)

The obvious reasons would be if the data frame was lost, or if the ACK was lost. Other possibilities include extremely slow processing on the receive side (late ACK).

Or Extremely Slow Processing of the ACK after it is received back at the send side.

From a neural network with 11 input variables, one hidden layer with three hidden units, and one output variable, how many param
e-lub [12.9K]

Answer:

40

Explanation:

Given that:

A neural network with 11 input variables possess;

one hidden layer with three hidden units; &

one output variable

For every input, a variable must go to every node.

Thus, we can calculate the weights of weight with respect to connections to input and hidden layer by using the formula:

= ( inputs + bias) × numbers of nodes

= (11 + 1 ) × 3

= 12 × 3

= 36 weights

Also, For one hidden layer (with 3 nodes) and one output

The entry result for every hidden node will go directly to the output

These results will have weights associated with them before computed in the output node.

Thus; using the formula

= (numbers of nodes + bais) output, we get;

= ( 3+ 1 ) × 1

= 4 weights

weights with respect to input and hidden layer total = 36

weights with respect to hidden and output layer total = 4

Finally, the sum of both weights is = 36 + 4

= 40

In a system where Round Robin is used for CPU scheduling, the following is TRUE when a process cannot finish its computation dur
masha68 [24]

Answer:

B. The process will be terminated by the operating system.

Explanation:

When Round Robin is used for CPU scheduling, a time scheduler which is a component of the operating system is used in regulating the operation. A time limit is set for each of the processes to be run.

So, when a process fails to complete running before its time elapses, the time scheduler would log it off and return it to the queue. This queue is in a circular form and gives each of the processes a chance to run its course.

Based on the contextual situation, the cable stations across the country from 8:00 p.m. to 10:00 p.m., or during <u>Late-fringe time</u>.

<h3>What is Late-Fringe Time?</h3>

Late Fringe time is a term used in television that describes the television hours that follow the prime time.

Generally, the prime period is usually between 8:00 p.m. to 10:00 p.m., while the Late Fringe time is around 11 p.m. to 1 a.m.

Hence, in this case, it is concluded that the correct answer is "<u>Late-Fringe period."</u>
