The answer is true

Technically, we have two types of firewall, a one way firewall and a two way. A one-way firewall will protect you from incoming threats. A two-way built-in or standalone firewall will add another layer of protection and thus, it is a must have tool.

2. Consider a 2 GHz processor where two important programs, A and B, take one second each to execute. Each program has a CPI of
allsm [11]

Answer:

program A runs in 1 sec in the original processor and 0.88 sec in the new processor.

So, the new processor out-perform the original processor on program A.

Program B runs in 1 sec in the original processor and 1.12 sec in the new processor.

So, the original processor is better then the new processor for program B.

Explanation:

Finding number of instructions in A and B using time taken by the original processor :

The clock speed of the original processor is 2 GHz.

which means each clock takes, 1/clockspeed

= 1 / 2GH = 0.5ns

Now, the CPI for this processor is 1.5 for both programs A and B. therefore each instruction takes 1.5 clock cycles.

Let's say there are n instructions in each program.

therefore time taken to execute n instructions

= n * CPI * cycletime = n * 1.5 * 0.5ns

from the question, each program takes 1 sec to execute in the original processor.

therefore

n * 1.5 * 0.5ns = 1sec

n = 1.3333 * 10^9

So, number of instructions in each program is 1.3333 * 10^9

the new processor :

The cycle time for the new processor is 0.6 ns.

Time taken by program A = time taken to execute n instructions

=  n * CPI * cycletime

= 1.3333 * 10^9 * 1.1 * 0.6ns

= 0.88 sec

Time taken by program B = time taken to execute n instructions

= n * CPI * cycletime

= 1.3333 * 10^9 * 1.4 * 0.6

= 1.12 sec

Now, program A runs in 1 sec in the original processor and 0.88 sec in the new processor.

So, the new processor out-perform the original processor on program A.

Program B runs in 1 sec in the original processor and 1.12 sec in the new processor.

So, the original processor is better then the new processor for program B.

1. A teacher asked a student to capture and print out a one-slide presentation using MSWord,       showing everything on the scr
Drupady [299]

The keyboard combinations that can be used to capture and print out a one-slide presentation using MSWord, showing everything on the screen is Function key + PrtScr

<h3>What is a Key Combination?</h3>

This refers to the procedure that is used to combine two or more keys on the keyboard to execute a task.

Hence, we can see that the procedure that can be used to carry out the operation is:

  • Enter the screen you want to capture and print
  • Press the Function key, followed by the PrtScr. Please note this can vary slightly, depending on the keyboard.

The hardware devices that would be needed to be set up by the system analyst at a computer laboratory are:

  • System Unit
  • Laptops/Monitor
  • Power adapters
  • Ethernet cables, etc

The database applications that can be recommended by the system analyst are:

  • MySQL,
  • SQL Server

The five word processing packages that are likely to be installed are:

  • G00..gle Docs
  • MsWord
  • MSOffice
  • Dropbox Paper
  • Corel WordPerfect
