Identify a true statement about a flat file system. a. Data in a flat file system can be updated efficiently. b. Data in a flat file system may not be updated in all files consistently. c. Data duplication in a flat file system is very efficient. d. Data in a flat file system can be easily managed.

Answer 1
Answer:

Answer:

The correct answer is D)

Data in a Flat File System can be easily managed.

Explanation:

When every file in the database is stored under a different name, it is often referred to as a Flat File System.

This system of filing is common with all Windows 95 computers and other operating systems since it's launch.

In a Flat File System, files are organised in a hierarchical file system with a hierarchy of directories and subdirectories, with every directory containing a certain number of files.

Cheers!

Consider the following two code segments, which are both intended to determine the longest of the three strings "pea", "pear", and "pearl" that occur in String str. For example, if str has the value "the pear in the bowl", the code segments should both print "pear" and if str has the value "the pea and the pearl", the code segments should both print "pearl". Assume that str contains at least one instance of "pea".I.if (str.indexOf("pea") >= 0){System.out.println("pea");}else if (str.indexOf("pear") >= 0){System.out.println("pear");}else if (str.indexOf("pearl") >= 0){System.out.println("pearl");}II.if (str.indexOf("pearl") >= 0){System.out.println("pearl");}else if (str.indexOf("pear") >= 0){System.out.println("pear");}else if (str.indexOf("pea") >= 0){System.out.println("pea");}Which of the following best describes the output produced by code segment I and code segment II?Both code segment I and code segment II produce correct output for all values of str.Neither code segment I nor code segment II produce correct output for all values of str.Code segment II produces correct output for all values of str, but code segment I produces correct output only for values of str that contain "pear" but not "pearl".Code segment II produces correct output for all values of str, but code segment I produces correct output only for values of str that contain "pearl".Code segment II produces correct output for all values of str, but code segment I produces correct output only for values of str that contain "pea" but not "pear".

A retail company assigns a $5000 store bonus if monthly sales are $100,000 or more. Additionally, if their sales exceed 125% or more of their monthly goal of $90,000, then all employees will receive a message stating that they will get a day off. When your pseudocode is complete, test the following monthly sales and ensure that the output matches the following. If your output is different, then review your decision statements.Monthly Sales Expected Output
monthlySales 102500 You earneda $5000 bonus!
monthlySales = 90000
monthlySales 112500 You earned a $5000 bonus!
All employees get one day off!

Answers

Answer:

To answer this question, i prepared a pseudocode and a program written in python;

Pseudocode begins here:

1. Start

2. Input montlySales

3. If monthlySales < 100000

3.1. Display Nothing

4. Else

4.1 Display “You earned a $5000 bonus!”

4.2 If monthlySales > 1.25 * 90000

4.2.1 Display “All employees get one day off!”

5.     Stop

Python Program starts here (See attachment for proper view of the program):

#Prompt user for input

monthlySales = float(input("Monthly Sales: "))

#Check monthlySales

if monthlySales < 100000:

     print("")

else:

     print("You earned a $5,000 bonus")

     if monthlySales > 1.25 * 90000:

           print("All Employees get the day off")

Explanation:

To answer this question, a conditional if statement is needed.

The pseudocode (and the program) starts by prompting user for input;

Then, the user input is first compared with 100,000

If it's less than 100,000; then nothing is displayes

However, if it is at least 100,000

"You earned a $5,000 bonus" is displayed

It further checks if the user input is greater than 125% of 90,000

If yes, "All Employees get the day off" is displayed else, nothing is displayed.

The pseudocode (and the program) stops execution, afterwards

A computer with a frequency 2 GHZ and its average cycle per instruction is 2. what is the MIPS of the computer?

Answers

Answer:

The correct answer is 1000 MIPS.

Explanation:

Using the rule of three you can solve the needed cycles to complete 1.000.000 instructions.

  • 1 instruction -> 2 cycles
  • 1.000.000 instructions -> x cycles.

1.000.000 instructions multiplied by 2 cycles, divided by 1 instruction is equal to 2.000.000 cycles to complete 1.000.000 instructions.

To find the MIPS you have to divide the frequency by the cycles needed to complete 1.000.000 instructions.

MIPS = 2GHZ / 2.000.000 cycles = 1000 MIPS.

suppose you have to implement an operating system on hardware that supports interrupts and exceptions but does not have an explicit trap (syscall) instruction. Can you devise a satisfactory substitute for traps using interrupts and/or exceptions? If so, explain how. If not, explain why. (In this context, the trap instruction is the instruction used by a user-level process to invoke a system call in the operating system, i.e., the trap instruction is the system call instruction

Answers

A trap is nothing but an exception that is caused by an abnormal condition. It is also used to invoke a system call or kernel routine because this has a higher priority than the user’s code. An interrupt is a response generated by the hardware which will occur at random times during the execution of the program. However, we cannot devise a substitute for traps using interrupts and exceptions because of the following reasons:

1. The interrupts are asynchronous whereas the exceptions and the traps are said to be synchronous.

2. The traps and exceptions can be manipulated or called whenever required whereas interrupts occur mostly at unwanted and random times.

To stop a process from happening, Ctrl + C is also done which is a user-defined interrupt in DOS operating systems

In this project you will write a set of instructions (algorithm). The two grids below have colored boxes in different locations. You will create instructions to move the colored boxes in grid one to their final location in grid two. Use the
example to help you. The algorithm that you will write should be in everyday language
(no pseudocode or programming language). Write your instructions at the bottom of the
page.
Example: 1. Move
the orange box 2
spaces to the right.
2. Move the green
box one space
down. 3. Move the
green box two
spaces to the left.
Write your instructions. Review the rubric to check your final work.
Rules: All 6 colors (red, green, yellow, pink, blue, purple) must be move to their new location on the grid. Block spaces are
barriers. You cannot move through them or on them – you must move around them
