Which of the following statements describes a limitation of using a computer simulation to model a real-world object or system?a. Computer simulations can only be built after the real-world object or system has been created.
b. Computer simulations only run on very powerful computers that are not available to the general public.
c. Computer simulations usually make some simplifying assumptions about the real-world object or system being modeled.

Answers

Answer 1

Answer:

Answer:

The answer is "Option c".

Explanation:

Computer simulation, use of a machine to simulate a system's vibration signals by another modeled system's behaviors. A simulator employs a computer program to generate a mathematical model or representation of a true system. It usually gives a lot of simplifications concerning the physical image or system that is modeled, so this statement describes the limitation of using a computer simulation in modeling a real-world object or process.

Our favorite program runs in 10 seconds on computer A, which has a 2 GHz clock. We are trying to help a computer designer build a computer, B, which will run this program in 6 seconds. The designer has determined that a substantial increase in the clock rate is possible, but this increase will affect the rest of the CPU design, causing computer B to require 1.2 times as many clock cycles as computer A for this program. What clock rate should we tell the designer to target?

Answers

Clock rate is simply the number of clock cycles a computer can perform in a second

Computer B should be designed to have a clock rate of 4GHz

The given parameters are:

$\mathbf{t_A = 10s}$ --- time on computer A

$\mathbf{c_A = 2GHz}$ --- computer A clock

$\mathbf{t_B = 6s}$ --- time on computer B

Start by calculating the period of computer A

$\mathbf{T_A = (1)/(c_A)}$

So, we have:

$\mathbf{T_A = (1)/(2GHz)}$

Rewrite as:

$\mathbf{T_A = (1)/(2 * 10^9 Hz)}$

So, we have:

$\mathbf{T_A = 0.5 * 10^(-9) s}}$

Next, we calculate the required number of clocks on computer A

$\mathbf{n_A = (t_A)/(T_A)}$

So, we have:

$\mathbf{n_A = (10)/(0.5 * 10^(-9))}$

$\mathbf{n_A = 20 * 10^(9)}$

Computer B requires 1.2 times as many clock cycles as A.

So, we have:

$\mathbf{n_B = 1.2 * n_A}$

This gives

$\mathbf{n_B =1.2 * 20 * 10^(9)}$

$\mathbf{n_B =24 * 10^(9)}$

The clock period of computer B is:

$\mathbf{T_B = (t_B)/(n_B)}$

So, we have:

$\mathbf{T_B = (6)/(24 * 10^(9))}$

$\mathbf{T_B = 0.25 * 10^(-9)}$

Lastly, the clock rate of computer B is:

$\mathbf{c_B = (1)/(T_B)}$

$\mathbf{c_B = (1)/(0.25 * 10^(-9))}$

$\mathbf{c_B = 4 * 10^(9)}$

Express in gigahertz

$\mathbf{c_B = 4 GHz}$

Hence, computer B should be designed to have a clock rate of 4GHz

"Packet switches have multiple links attached to them. For each attached link the packet switch has a/an ____________, which stores packets that the router is about to send into that link."link buffer

access buffer

output buffer

transmission buffer

none of the above

Answers

Answer: Output buffer

Explanation:

Each packet switches contain multiple links which are attached to it and for individually attached link the output buffer basically store packets. Then, the router send these packets into multiple links.

In output buffer, if the packets are transmitted into the links but it finds that the link is busy with the another packet for transmission. Then, that particular packet needs to be wait in output buffer.

Therefore, the output buffer is the correct option.

Is the willingness to put a customer’s needs above ones own needs and to go beyond a job description to achieve customer satisfaction

Answers

Answer:

customer-serious orientation

Explanation:

Customer-serious orientation can be defined as the willingness to put a customer’s needs above ones own needs and to go beyond a job description to achieve customer satisfaction.

This ultimately implies that, a customer-serious oriented business firm or company puts the needs, wants and requirements of its customers first without considering their own needs in a bid to satisfy and retain them.

Hence, customer-serious orientation requires the employees working in an organization to show and demonstrate positive attitudes and behaviors at all times.

What is communication?

The term communication refers to the exchange of thoughts, ideas, and messages that are shared between two or more people. Without language, a person can survive, but without communication, no one can survive. Communication is divided into two categories, such as interpersonal and intrapersonal.

Advantages of the communication with the used of the technology are:

Quickly communicate.
Easy to used.
Managed the data and share the data easily.

Disadvantages of the communication with the used of the technology are:

Privacy issues.
Hacking Data.
They recover the data all the time not to the easy.

Hence, the significance of the communication are the aforementioned.

ADVANTAGES:

First, the evolution of technology is beneficial to humans for several reasons. At the medical level, technology can help treat more sick people and consequently save many lives and combat very harmful viruses and bacteria.

2-Technology has also increased the productivity of almost every industry in the world. Thanks to technology, we can even pay with bitcoins instead of using banks

DISADVANTAGES:

1-Lack of Privacy. You might think that a quick text or IM offers more privacy than a telephone call in a crowded room. ...

2-Distraction from Real Life. ...

3-Potential for Misunderstanding. ...
