Consider two packet switches directly connected by a link of 5000 km,
propagation speed 2.5 X10^8 m/s and transmission rate 1 Mbps. How long does it take to move
a packet of length 1,000 bytes from one packet switch to the other packet switch? Generally,
how long does it take to move a packet of length L over a link of distance d, propagation speed
s, and transmission rate R bps?

Answers

Answer 1

The time that is required for the packet to move over the the distance d at the speed s is  0.028 seconds.

The speed that It would take to move it in transmission is given as 0.008 seconds.

How to solve for the required time

The details that we would have to solve the problem that we have here are given below

The distance = 5000 km, we convert to meters = 5000 * 1000

The speed of the propagation is given as (s) 2.5 x 108 m/s

The propagation delay is given as d / s

= 5000000 / 2.5 x 10^8

= 0.02 this is the value of the propagation

Next we have to find the length of the packet. L = 1000 bytes

this is equal to 8000 bits

The transmission rate is 1 Mbps = 1000000 bits

The transmission delay would be = L/R

= 8000 / 1000000

= 8 / 1000

= 0.008 seconds in transmission

The total required time that is to be gotten would be

Propagation + transmission

= 0.02 + 0.008

= 0.028

Do programming languages give computer instructions?

Using computer programming languages, we can communicate with a computer in a language that it can understand.

There are numerous computer programming languages available that programmers can use to interact with a computer, just as there are numerous human-based languages.

Therefore, a programming language is seen as a set of rules that tends to  gives the computer instructions on what actions to take. There are a lot of programming languages; some examples are BASIC, COBOL, and others.

Parallel Computing and Distributed Computing
Sequential computing has been great, but computer scientists need every speed and storage advantage they can get. Clever computer scientists have found even more efficient ways to use computer hardware for certain types of problems.

parallel Computing
Parallel computing ​is the use of a computer that performs multiple instructions at the same time. The programs used for parallel computing must be designed so they can be broken down into smaller independent parts that each processor can work on.

Parallel computing uses multiple computing cores. A computing core​ is one processor in the CPU. Parallel computers will have many different processors in their CPUs instead of just one.

Speedup in Parallel Computing
The advantage of a parallel computing solution over a sequential computing solution can be measured in speedup. Speedup​ is the amount of time used to perform a task with sequential computation divided by the amount of time used to perform the same task with parallel computation.

For example, imagine that you run a program on a sequential computer and it takes 10 minutes to complete. Next, you run the same program on a parallel computer and it takes 5 minutes to complete. You would divide the 10 by the 5 and come up with a speedup of 2. This means your program is two times faster on a parallel computer.

Distributed Computing
Many computer problems are so complex that they take an extremely long time to run on one computer. Distributed computing​ is the use of multiple computers to solve a problem. Distributed computing is like parallel computing but with many different computers; parallel computing is the use of one computer with many different processors.

QUESTION:

Parallel computing refers to the study, design, and execution of algorithms in order to solve a problem using many processors. The basic goal is to solve a problem quicker or larger issue in the same amount of time by sharing the work among many processors.

Parallel computing has the advantage of allowing computers to run code more effectively, saving time and money by sorting through "huge data" faster than ever before. Parallel programming can also handle more difficult issues by pooling resources.
