Answer:
1. Processor communication -- this involves the following tasks:
<em>a. exchange of data between processor and I/O module</em>
<em>b. command decoding - I/O module accepts commands sent from the processor. E.g., the I/O module for a disk drive may accept the following commands from the processor: READ SECTOR, WRITE SECTOR, SEEK track, etc. </em>
<em>c. status reporting – The device must be able to report its status to the processor, e.g., disk drive busy, ready etc. Status reporting may also involve reporting various errors. </em>
<em>d. Address recognition – Each I/O device has a unique address and the I/O module must recognize this address. </em>
<em />
2. Device communication – The I/O module must be able to perform device communication such as status reporting.
3. Control & timing – The I/O module must be able to co-ordinate the flow of data between the internal resources (such as processor, memory) and external devices.
4. Data buffering – This is necessary as there is a speed mismatch between speed of data transfer between processor and memory and external devices. Data coming from the main memory are sent to an I/O module in a rapid burst. The data is buffered in the I/O module and then sent to the peripheral device at its rate.
5. Error detection – The I/O module must also be able to detect errors and report them to the processor. These errors may be mechanical errors (such as paper jam in a printer), or changes in the bit pattern of transmitted data. A common way of detecting such errors is by using parity bits.
Answer:
import java.util.Scanner; public class Salesman2 {
public static void main(String[] args) { // TODO Auto-generated method stub double CommissionRate;
double TotalSales, Commission;
Scanner Read = new Scanner (System.in); System.out.println("Please enter total sales "); TotalSales=Read.nextDouble();
if (TotalSales<500)
CommissionRate=0.0;
else if (TotalSales>=500 && TotalSales <1000) CommissionRate=0.05;
else
CommissionRate=0.08;}
Commission = CommissionRate * TotalSales;
System.out.println("The Commision is: "+ Commission); }
}
}
The block most effectively keep a sprite from moving off the screen if if on edge, bounce. Hence option B is correct.
<h3>
What is screen?</h3>
Screen is defined as a portable or stationary object that offers shelter, acts as a partition, etc., and often consists of a covered frame. Screening is defined as the procedure of locating or choosing individuals from a community according to one or more selection criteria.
The block will kept more perfectly if one of the edge there is bounce so that the box will not fall from the sprite.
Thus, the block most effectively keep a sprite from moving off the screen if if on edge, bounce. Hence option B is correct.
