a. a large central network that connects other networks in a distance spanning exactly 5 miles.
b. a group of personal computers or terminals located in the same general area and connected by a common cable (communication circuit) so they can exchange information.
c. a network spanning a geographical area that usually encompasses a city or county area (3 to 30 miles).
d. a network spanning a large geographical area (up to 1000s of miles).
e. a network spanning exactly 10 miles with common carrier circuits.

A wide area network is a network spanning a geographical area that usually encompasses a city or county area, it may be spanning a large geographical area. Hence, options A, B, C, and D are correct.

While the other options are incorrect because:

Option A is incorrect because WAN is specially designed for the specific purpose of the organization to share the data with other offices in their geographic area. Also, option E is not correct because WAN may cover exactly 10 miles for some organizations but it is not necessary to connect with a common carrier circuit.

(Hours, minutes, and seconds) Write a method that returns a string in the form of hour:minute:second for a given total seconds using the following header:
public static String format(long seconds)
Here is a sample run:

Enter total seconds: 342324
The hours, minutes, and seconds for total seconds 342324 is 23:05:24

Note that a zero is padded to hour, minute, and second if any of these values is a single digit.

When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This adjustment can be done by normalizing to values between 0 and 1, or throwing away outliers.
For this program, adjust the values by dividing all values by the largest value. The input begins with an integer indicating the number of floating-point values that follow.
Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
print('{:.2f}'.format(your_value))
Ex: If the input is:
5 30.0 50.0 10.0 100.0 65.0
the output is:
0.30 0.50 0.10 1.00 0.65
The 5 indicates that there are five floating-point values in the list, namely 30.0, 50.0, 10.0, 100.0, and 65.0. 100.0 is the largest value in the list, so each value is divided by 100.0.
For coding simplicity, follow every output value by a space, including the last one

Parts arrive at a two-machine system according to an exponential interarrival distribution with mean 20 minutes. Upon arrival, the parts are sent to Machine 1 and processed. The processing-time distribution is TRIA (4.5, 9.3, 11) minutes. The parts are then processed at Machine 2 with a processing-time distribution as TRIA (16.4, 19.1, 20.8) minutes. The parts from Machine 2 are directed back to Machine 1 to be processed a second time (same processing-time distribution but an independent draw from it). The completed parts then exit the system. Run the simulation for a single replication of 20,000 minutes to observe the average number in the machine queues and the average part cycle time with Arena Model
