Answer:

A small office or business will typically only need a LAN. The local network will ensure that different files can be transferred through your office leading to a connected business environment. If you have a larger business or multiple branches, that's when you're going to need a WA

8.14 Consider a system in which bus cycles takes 500 ns. Transfer of bus control in either direction, from processor to I/O devi

alexira [117]

Answer:

A) 2.56 ms

B) 128 μs

Explanation:

Time for Bus cycles = 500 ns

Transfer of bus control = 250 ns

I/0 device data transfer rate = 50 KB/s

Data are transferred at : 1 byte at a time

A) Determine how long the device tie up the bus when transferring a block of 128 bytes

Block size to be transferred = 128 bytes

Bandwidth = 50 KB/s

data transfer = (Block size ) / ( Bandwidth)

= ( 128 * 8 ) / ( 50 * 10^3 * 8 )

= ( 1024 ) / ( 50 * 10^3 * 8 )

= 2.56 ms

To determine the actual transfer time we have to add up the transfer time for the bus control in both directions :

2.56 ms + 500 ns = 2.56 ms. this is because 500 ns is not a significant value

B) cycle stealing mode

In this mode each byte is transferred at a time and The total transfer time needed for the bus control in both directions will be double the total time i.e 2 * 500 ns = 1000 ns. because additional control time of 250 ns is required at both ends

since 1 byte is transferred at a time , 1 byte will be transferred in 1 μs

128 bytes = 128 * 1 μs = 128 μs

A year in the modern Gregorian Calendar consists of 365 days. In reality, the earth takes longer to rotate around the sun. To ac

denpristay [2]

Answer:

import java.util.Scanner;

public class LabProgram {

public static void main(String[] args) {

Scanner scnr = new Scanner(System.in);

int inputYear;

boolean isLeapYear;

isLeapYear = false;

inputYear = scnr.nextInt();

// If a year is divisible by 400, then it is a leap year

if (inputYear % 400 == 0)

isLeapYear = true;

// If a year is divisible by 100, then it is not a leap year

if (inputYear % 100 == 0)

isLeapYear = false;

// If a year is divisible by 4, then it is a leap year

if (inputYear % 4 == 0)

isLeapYear = true;

if(isLeapYear)

System.out.println(inputYear + " is a leap year.");

else

System.out.println(inputYear + " is not a leap year.");

}

Explanation:

If a year is divisible by 400, then set the boolean isLeapYear to true. If a year is divisible by 100, then set the boolean isLeapYear to false. If a year is divisible by 4, then set the boolean isLeapYear to true.

Check if isLeapYear is true, then print that it is a leap year. Otherwise, print that it is not a leap year.

Output:

1712

1712 is a leap year.

When you are pasting an item, what choice will the Paste Options button offer you?

Monica [59]

The Paste Options button becomes available when you paste data into cells in Excel. The button appears just below the pasted selection.

Write an interface, PointingDevice, containing: an abstract method, getXCoord that returns an int an abstract method, getYCoord

vaieri [72.5K]

Answer:

Following are the code in java language

abstract interface PointingDevice // interface PointingDevice,

{

// abstract method getXCoord()

public abstract int getXCoord();

// abstract method getYCoord()

public abstract int getYCoord();

// abstract method attentionRequired()

public abstract boolean attentionRequired();

// abstract method setResolution( )

public abstract double setResolution(double a);

}

Explanation:

In this code we have declared a abstract interface "PointingDevice" which contains the four abstract method getXCoord of type int , getYCoord() of type int , attentionRequired() of type boolean and setResolution() of type double .

These method have only declaration not definition any interface or class which inherit the inteface PointingDevice must define all these four method otherwise it also be abstract .
