Write a program that, given a file name typed by the user, reads the content of the file and determines the highest salary, lowest salary and average salary. The file contains employee records, and each record consists of the hours worked and the hourly rate. The salary is calculated as the product of the hours worked and the hourly rate.
An example of file containing three records is as follows:
10.5 25.0
40.0 30.0
30.9 26.5
Using the pandas packge in python, the program which performs the required calculation goes thus :
file_name = input()
#user types the filename
df = pd.read_csv(file_name, names=['hours_worked', 'rate']
#file is read into a pandas dataframe
df['salary'] = df['hours_worked'] * df['rate']
#salary column is created using the product of rate and hours worked
highest_salary = df['salary'].max()
#the max method returns the maximum value of a series
print('highest_salary)
lowest_salary = df['salary'].min()
#the min method returns the minimum value of a series
print('lowest_salary)
avg_salary = df['salary'].mean()
#the mean method returns the average value of a series
print('avg_salary)

Assume that the speed of new computers costing a certain amount of money grows exponentially over time, with the speed doubling every 18 months. Suppose you need to run a very time consuming program and are allowed to buy a new computer costing a fixed amount on which to run the program. If you start now, the program will take 7 years to finish. How long should you delay buying the computer and starting the program so that it will finish in the shortest amount of time from now
Therefore, in order to run the program in the shortest time, you should delay for 3 years
Given that the speed of new computers costing a certain amount of money grows exponentially over time, with the speed doubling every 18 months.
Exponential equation as a function of time can be expressed as
P(t) = [tex]P_{0}[/tex][tex]R^{t/T}[/tex]
Quantity P will be increasing exponentially when R > 1. And it will decrease exponentially when R < 1.
Suppose you need to run a very time consuming program and are allowed to buy a new computer costing a fixed amount on which to run the program. If you start now, the program will take 7 years to finish.
Let the time required to run and complete a program for time t years be P(t).
If the speed doubling every 18 months, which is 3/2 years. This will eventually cause the running time to decrease by half (0.5)
P(t) = 7[tex](1/2)^{3t/2}[/tex] = 7[tex](2)^{-3t/2}[/tex]
The total time T will be sum of the delay time t and the time of running the program. That is
T(t) = t + P(t)
T(t) = t + 7[tex](2)^{-3t/2}[/tex] .......... (2)
We can calculate the minimum time t by differentiating the above equation and make it equal to zero.
dT/dt = 1 + 14/3[tex](2)^{-3t/2}[/tex](ln0.5) = 0
14/3[tex](2)^{-3t/2}[/tex](ln0.5) = -1
[tex](2)^{-3t/2}[/tex](ln0.5) = -3/14
[tex](2)^{-3t/2}[/tex] = -3/14ln0.5
Log (natural logarithm) both sides
-3t/2ln2 = ln(3/14ln2)
make t the subject of formula
t = - 3ln(3/14ln2) ÷ 2ln2
t = 2.5 approximately
To know how long you should delay buying the computer and starting the program so that it will finish in the shortest amount of time from now, substitute t into equation 2
T(2.5) = 2.5 + (7)[tex]2^{-3(2.5)/2}[/tex]
T(2.5) = 2.5 + 0.5202
T(2.5) = 3.02 years
T (2.5) = 3 years approximately
Therefore, in order to run the program in the shortest time, you should delay for 3 years

discuss the communicatin process giving detailed explanation on each process
Communications is fundamental to the existence and survival of humans as well as to an organization. It is a process of creating and sharing ideas, information, views, facts, feelings, etc. among the people to reach a common understanding. Communication is the key to the Directing function of management.
A manager may be highly qualified and skilled but if he does not possess good communication skills, all his ability becomes irrelevant. A manager must communicate his directions effectively to the subordinates to get the work done from them properly.
Communications ProcessCommunications is a continuous process which mainly involves three elements viz. sender, message, and receiver. The elements involved in the communication process are explained below in detail:
1. Sender
The sender or the communicator generates the message and conveys it to the receiver. He is the source and the one who starts the communication
2. Message
It is the idea, information, view, fact, feeling, etc. that is generated by the sender and is then intended to be communicated further.
Browse more Topics under Directing
Introduction, Meaning, Importance & Principles of DirectingElements of DirectionIncentivesLeadership3. Encoding
The message generated by the sender is encoded symbolically such as in the form of words, pictures, gestures, etc. before it is being conveyed.
4. Media
It is the manner in which the encoded message is transmitted. The message may be transmitted orally or in writing. The medium of communication includes telephone, internet, post, fax, e-mail, etc. The choice of medium is decided by the sender.
5. Decoding
It is the process of converting the symbols encoded by the sender. After decoding the message is received by the receiver.
6. Receiver
He is the person who is last in the chain and for whom the message was sent by the sender. Once the receiver receives the message and understands it in proper perspective and acts according to the message, only then the purpose of communication is successful.
7. Feedback
Once the receiver confirms to the sender that he has received the message and understood it, the process of communication is complete.
8. Noise
It refers to any obstruction that is caused by the sender, message or receiver during the process of communication. For example, bad telephone connection, faulty encoding, faulty decoding, inattentive receiver, poor understanding of message due to prejudice or inappropriate gestures, etc.

Imagine you were going to use a dedicated workstation for an animation job rather than a personal PC. What differences would you expect to see between a dedicated 3D animation workstation and a typical PC
I'm no expert here, as I don't own a workstation but rather a gaming pc. But hey, I did tons of research on pc components and I think I can answer your question.
A dedicated workstation would be FAR more capable of running 3d applications, given how demanding they can get than a personal PC. You'd instantly regret using a typical pc for 3d rendering, even a top of the line gaming pc. Point is, gpus created by nvidia are far more capable of running graphic intensive programs specifically made for work than any other gpu. If you want to be satisfied, i'd advise you go for a workstation (Plus they're so much easier to get your hands on than a gaming rig).

Laptop computers are difficult to repair, upgrade or modify due to their closed and integrated design. While storage drives and RAM are usually accessible because these are the things you will most likely upgrade, it is often difficult to modify or replace your CPU, graphics chip or motherboard. These jobs will usually require professional equipment and tools–or a hired professional technician. Additionally, while in a desktop computer the possible configurations are almost unlimited, laptop configurations are limited to those provided by laptop manufacturers. Some software may also be incompatible with laptop hardware, and installations of different operating systems than those bundled with the laptop may result in hardware failures.
