* Create a list of places and situations in which we use a computer

Vinvika [58]

Answer:

Place:

Coffee shop. Railway Reservation System, Airport Reservation System, Machine learning and a long list follow.

Situation:

We find that there is a similar type of calculation and in bulk. Thus we can create a piece of software, and run that with the help of a computer to solve our problem of tackling the massive number of clients.

Description:

The situation demands a similar sort of calculation, and we can hence make a program or most favorably a software that can do all these calculations for us. A perfect example is a coffee shop, which has 100 to 1000 customers drinking coffee each second. And you can understand how badly they need a computer and software. This cannot be done manually.

Select the proper ergonomic keyboarding techniques.

SCORPION-xisa [38]

Answer:

The correct options are;

-Position the keyboard directly in front and close to you so you don't have an excessive reach

-Keep your shoulders, arms, hands and fingers relaxed

-Position your wrists straight or in neutral position while typing

-Adjust your chair height and position so your feet rest flat on the floor, or add a footrest to compensate for a higher chair

-Adjust the keyboard height so that your shoulders can relax and your arms are straight in front of you

Explanation:

1) It is important to keep the fingers in a relaxed position when typing

2) Ensure to type in a tapping fashion when typing rather than pressing on the keys of the keyboard

3) The fingernails should be kept short when frequent typing is done

4) The wrist is better kept above the keyboard than resting on it

5) Ensure that the mouse is easily reached.

Gennadij [26K]

Answer:

The program in Java will be:

// Java program to demonstrate working parseInt()

public class GFG

{

public static void main(String args[])

{

int decimalExample = Integer.parseInt("20");

int signedPositiveExample = Integer.parseInt("+20");

int signedNegativeExample = Integer.parseInt("-20");

int radixExample = Integer.parseInt("20",16);

int stringExample = Integer.parseInt("geeks",29);

// Uncomment the following code to check

// NumberFormatException

// String invalidArguments = "";

// int emptyString = Integer.parseInt(invalidArguments);

// int outOfRangeOfInteger = Integer.parseInt("geeksforgeeks",29);

// int domainOfNumberSystem = Integer.parseInt("geeks",28);

System.out.println(decimalExample);

System.out.println(signedPositiveExample);

System.out.println(signedNegativeExample);

System.out.println(radixExample);

System.out.println(stringExample);

More registers appear to be a good thing, in terms of reducing the total number of memory accesses a program might require. Give

gulaghasi [49]

Answer:

Following is given the answer step by step:

Explanation:

First of all we will write a program using MARIE that will support the statement: Sum = (A + B) - (C + D). All the necessary comments are given in front of each statement:

Load A # variable A will be loaded

Add B # B will be added to A

Store Temp1 # A + B will be stored in Temp1

Load C # C will be loaded in memory

Add D # D will be added to C

Store Temp2 # C + D will ge stored in Temp2

Load Temp1 # Temp1 will be loaded in the memory

Subt Temp2 # Temp2(A + B) get subtracted from Temp1(A - B)

Store Sum # (A + B) - (C + D) will get stored in Sum.

We can see from above program that memory is accessed 9 times. While if C + D get executed first than memory accesses will be reduced to 7.

Above same program could be written using an architecture of 4 registers:

The program is as follows:

Load R1 , A #A will be loaded into R1

Load R2 , B # B will be loaded into R2

Add R1 , R2 # R2 gets added to R1 and the result is stored in R1 (A + B)

Load R3 , C # C loaded into R3

Load R4 , D # D loaded into R4

Add R3 , R4 # Value in R4 gets added into R3 and R3 becomes (C + D)

#no memory accesses required for this operation

Subt R1 , R4 #R4 (C + D) gets subtracted from R1 (A + B)

#no memory accesses required for this operation

Store Sum # The recent value will be stored into Sum

Here memory is accessed 5 times in total.
