On large computers, the operating system switches back and forth among multiple programs stored in memory in order to overlap in

put and output operations with processing time; the purpose of this switching is to maximize the work done by the CPU. What is this concept of switching among multiple programs in memory called?

Answer:

Multiprogramming

Explanation:

<u>Multiprogramming:</u> In a modern computing system, there are usually several concurrent application processes which want to execute. Now it is the responsibility of the Operating System to manage all the processes effectively and efficiently.

One of the most important aspects of an Operating System is to multi program.

In a computer system, there are multiple processes waiting to be executed, i.e. they are waiting when the CPU will be allocated to them and they begin their execution. These processes are also known as jobs. Now the main memory is too small to accommodate all of these processes or jobs into it. Thus, these processes are initially kept in an area called job pool. This job pool consists of all those processes awaiting allocation of main memory and CPU.

CPU selects one job out of all these waiting jobs, brings it from the job pool to main memory and starts executing it. The processor executes one job until it is interrupted by some external factor or it goes for an I/O task.

write a single expression that will return true if the lower four bits of x are the same as the lower four bits of y
horrorfan [7]

A single expression that will return true if the lower four bits of x are the same as the lower four bits of y is; (x & 0x0F) == (y & 0x0F)

<h3>How do you write single expression programs?</h3>

There are different methods of writing programs such as python and others. However, in this case, it is pertinent to know that this compiler that will return true if the lower four bits of x are the same as the lower four bits of y doesn't accept binary constants and as such we will use hexidecimal instead. For example; for 0b00111111, we will use 0x3F.]

Thus, using that same concept above, the single expression that will return true if the lower four bits of x are the same as the lower four bits of y is; (x & 0x0F) == (y & 0x0F)

Explain why it is important to continually evaluate long-term goals
lilavasa [31]
It is important to continually evaluate long term goals because one's life situation can change from day to day. For example, one can be without work for many months and despairing of ever getting work when finally conditions improve and work becomes available. Life is full of opportunities and sooner or later opportunities will arise so that whereas the long term situation looked economically bleak before, now it can improve significantly.

Write the definition of a function isSenior, that receives an integer parameter and returns true if the parameter's value is gre
ohaa [14]

Answer:

The function definition for this question can be given as:

Function Definition:

bool isSenior(int x )  //function

{  

//function body Or function definition.

//conditional statement

//if statement

if (x >=65)  

{

return true;   //return value true.

}

else  //else statement

{

return false;    //return value false.

}

}

Explanation:

In the above function definition firstly we define a function that isSenior. This function return Boolean value that is true or false in this function we pass the value as the parameter in that function we use the if statement that check the pass value is greater then equal to 65. If the condition is true it return true.else it will return false.
