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:
A program takes 10 minutes to compute sequentially and has a speedup of 2 on a parallel computer, meaning it takes how many minutes. ??

When Lowell Thomas produced 4,000 units during his 40 hour workweek and his regular rate of pay is $0.12 per unit, the overtime pay is C. $19.50 per hour.

The number of hours a worker works in excess of what is required for a typical workweek is calculated as their overtime rate. Depending on how overtime is defined by the labor laws of each country and jurisdiction, this rate may have various implications in each.

The overtime premium or the overtime rate of pay are typical names for overtime compensation. The most common overtime rate is time and a half, which is 50% more than the employee's hourly pay. It means that you will receive 1.5 times your regular hourly rate for every hour of overtime worked.

The overtime will be calculated thus:

Multiply $0.12 4,000 = $480

Multiply regular pay, $0.04 1,000 = $40

Add: Bonus pay, $480 + $40 = $520,

Divide $520/40 = $13.00/hr

Multiply the rate: $13.00 * 1.5 = $19.50/hr.

Therefore, the overtime is $19.50.

Storage is one of the most important things to think about because, if you do not have enough storage then the update only hurts you. Then plus you cannot even get the update in most cases. How it changes the layout and how it changes the computers is important because it can be what makes a person hate the newest software or not. If the layout changes to something you do not agree with, then it can leave a person all mixed up. Lastly how it differs is important because, how it differs from the previous can be the reason why or why not you even need the update. The differences could be good or bad.

A statement with a hypothesis and a conclusion is known as a conditional statement (also known as an If-Then Statement). "If this happens, then that will happen" is another approach to define a conditional statement. The initial clause, or "if," of a conditional statement is the hypothesis.

Note that the hypothesis is a prediction of what will transpire in your experiment. The terms "IF" and "THEN" are frequently used when writing the hypothesis. For instance, "I will fail the exam if I don't read." Your independent and dependent variables are reflected in the "if" and "then" statements.
