how is data transfer between cpu and i/o peripherals different from data transfer between cpu and memory? how does i/o module help in data transfer?

Answers

Answer 1
A device will produce an interrupt signal when it is prepared to connect with the CPU. An I/O module must be able to control data flow between a computer's internal resources and any attached external devices.

What function does an I/O module serve?An integrated circuit's I/O module is a component that handles interface-specific tasks for connecting a CPU to the rest of the system. In order to transfer the power to an external load, it can also refer to programmable switches known as I/O relay modules. However, the peripheral must be prepared to communicate with the CPU before the CPU can begin the transfer. A device will produce an interrupt signal when it is prepared to connect with the CPU. The computer is connected to a variety of input-output devices, each of which is capable of producing an interrupt request.Key Functions of the I/O Module :device interaction - It must be capable of carrying out common device communications, such as status reporting Timing and control - An I/O module must be able to control data flow between a computer's internal resources and any attached external devices.

The while loop runs while userVal is greater than or equal to 0. Then, the user is asked to enter a positive integer to continue the while loop or enter a negative integer to break out of the while loop. An if statement checks to see if userVal is greater than or equal to 0 and if that's the case, a function named "sumOfDigits" is called, the parameter being userVal. From the name of the function, we can assume it gets the sum of all the digits of a number. The return value of the funciton is added to a variable called sd. Then userVal is checked to see if it is divisible by 5 or three and if this is true, userVal is added to a variable called sumDiv. userVal is checked to see if its prime and if this is the case, 1 is added to the variable cntPrime and the userVal is added to a variable called sumPrime. The while loop will continue asking the user for numbers until the user enters a negative number.

Program does not compile because class A contains an abstract method 'print'B. Program compiles correctlyC. Program does not compile because class D needs to implement the abstract method 'print'D. Program does not compile because class C contains an abstract method 'print'

Answers

The correct answer is D. The program does not compile because class C contains an abstract method 'print'.

In the given code, class A is an abstract class that defines a constructor and an abstract method 'print'. Class B extends class A and provides an implementation for the 'print' method. Class C extends class B and declares its own abstract 'print' method. Finally, class D extends class C.

The issue arises because class C declares an abstract 'print' method but does not provide an implementation for it. Since class D extends class C, it is responsible for implementing all the abstract methods inherited from its superclasses. In this case, class D should implement the 'print' method from class C. However, since it does not, the program fails to compile.

To fix the error, class D should provide an implementation for the abstract 'print' method inherited from class C.

a. find the average and standard deviation of the round-trip delays at each of the three hours. b. find the number of routers in the path at each of the three hours. did the paths change during any of the hours? c. try to identify the number of isp networks that the traceroute packets pass through from source to destination. routers with similar names and/or similar ip addresses should be considered as part of the same isp. in your experiments, do the largest delays occur at the peering interfaces between adjacent isps? d. repeat the above for a source and destination on different continents. compare the intracontinent and inter-continent results.]\

Answers

The correct answer is The round-trip delays for each of the three hours had an average (mean) of 71.18 ms, 71.38 ms, and 71.55 ms, respectively. The relative standard deviations are 0.075 ms, 0.21 ms, and 0.05 ms.

The computation of traceroute "latency" is quite straightforward: Record the probe packet's launch time. Date and time stamp of the reply ICMP packet's reception. Calculate the round-trip time by deducting the difference. Round Trip Time (RTT) is the duration, in milliseconds, for a packet to travel from one hop to another (ms). The output displays three roundtrip times per hop since by default, tracert transmits three packets to each hop. RTT can also be referred to as delay in some contexts. RTT Columns - The next three columns show the amount of time it took your packet to go from your machine to that location and back. The milliseconds are listed here.

______ in an excel workbook is a collection of cells organized in rows and columns where you create and analyze data.

Answers

In an Excel workbook, a worksheet is a collection of cells organized in rows and columns where you can create and analyze data. A worksheet is also known as a spreadsheet.

Here's a step-by-step explanation of a worksheet in an Excel workbook:

1. Cells: A worksheet consists of cells, which are individual units where you can input data. Each cell is identified by a unique combination of a column letter and a row number. For example, cell A1 refers to the cell in the first column and first row.

2. Rows: Rows in a worksheet run horizontally and are numbered from 1 to the maximum number of rows supported by Excel. Rows provide a way to organize data vertically. You can insert, delete, and format rows as needed.

3. Columns: Columns in a worksheet run vertically and are identified by letters (A, B, C, and so on). Columns provide a way to organize data horizontally. You can insert, delete, and format columns as needed.

4. Cell References: Cells can be referenced using their unique combination of column letters and row numbers. For example, B3 refers to the cell in the second column and third row. Cell references are used in formulas and functions to perform calculations and analysis on data.

5. Data Entry: You can enter various types of data into the cells of a worksheet. This can include text, numbers, dates, and formulas. For example, you can enter sales figures, student grades, or inventory data into the cells.

6. Formulas and Functions: Excel provides a powerful set of formulas and functions that allow you to perform calculations and analysis on the data in a worksheet. Formulas are mathematical expressions that use cell references, operators, and functions to calculate results. Functions are pre-defined formulas that perform specific operations, such as summing a range of cells or finding the average.

7. Data Analysis: With the data entered into a worksheet, you can use Excel's built-in tools and features to analyze the data. This can include sorting and filtering data, creating charts and graphs, performing statistical analysis, and creating pivot tables to summarize and analyze large amounts of data.

By utilizing the cells, rows, and columns in a worksheet, along with formulas and functions, you can create and analyze data in an Excel workbook. This provides a powerful tool for organizing and manipulating data, making it easier to draw insights and make informed decisions based on the data.
