Binary arithmetic is an essential part of all the digital computers and many other digital systems.

Binary Addition:

It is a key for binary subtraction, multiplication, division. The four rules of the binary addition are:

0 + 0 = 0

0 + 1 = 1

1 + 0 = 1

1 + 1 = 0 with a carry bit 1 112

Binary Subtraction:

Subtraction and borrow, these two words will be used very frequently for the binary subtraction. The four rules of the binary subtraction are:

0-0 = 0

0-1=0 with a borrow 1

1 - 0 = 1

1 - 1 = 0

• Name of the array is marks.
• Type of the array is integer.
• Size of the array is 6. i.e., we can store up to 6 integer values in the array.

1.  First-generation computers:

The first computers used vacuum tubes for electronic circuitry and magnetic drums for memory. They were very expensive to operate and the power consumption was high, generated a lot of heat, which was often the cause of malfunctions.

2.  Second-generation computers:

In the second generation computers, symbolic or assembly languages were used. High-level programming languages were also in use at this time, such as early versions of COBOL and FORTRAN. Their memory consisted of magnetic core technology. 

• The processing speed and efficiency of computers increased. 
• Keyboards and monitors were used as input and output devices.
• Computer system had an operating system and helped to run multiple applications simultaneously.

Six commonly found errors in a C program are:

1. Missing or misplaced ; or }, missing return type for a procedure, missing or duplicate variable declaration

2. Type mismatch between actual and formal parameters, type mismatch on assignment.

3. Forgetting the precedence of operators, declaration of function parameters. 

4. Output errors means the program runs but produces an incorrect result. This indicates an error in the meaning of the program. 

5. Exceptions that include division by zero, null pointer and out of memory. 

6. Non-termination means the program does not terminate as expected, but continues running "forever."

A linked list is called a dynamic data structure because it can be used with a data collection that grows and shrinks during program execution. The major advantage of using linked list over arrays is in implementing any data structure like stack or queue. The arrays are fixed in size and so a lot of memory gets wasted if we declare in prior the estimated size and the used space is less. Also it is not time efficient to perform deletion, insertion and updating of information in an array implementation because of its fixed length memory storage. A linked list allocation storage result in efficient use of memory and computer time. Linked lists are useful over arrays because:

The exact amount of memory space required by a program depends on the data being processed and so this requirement cannot be found in advance. Linked list uses runtime allocation of memory resulting in no wastage of memory space. 

Some programs require extensive use of data manipulation like insertion of new data, deletion and modification of old data. Linked lists are self referential structures so provide an efficient time complexity for these operations.

Correct option (2)  1.0 V 

Explanation: 

V₁ = 40 x 10^-3 x 50 = 2V

V₂  =  1 V  

Correct option  (3)  0.6 V

Explanation:

V₅  = I₁ x R₅  = 0.02 x 30 = 0.6 V

The story definitely reminds one of “Birth” by A. J. Cronin. There is a striking similarity between both the stories. Both revolve around doctors who try their level best to save the lives of nearly dead human beings. In the story “Birth” Dr Andrew saves the life of an almost still born baby boy with lot of effort, while “The Enemy” deals with the story of Dr Sadao who saves an American soldier from the enemy troops during the times of war. Both the stories deal with humanity, love, affection, selflessness, and a strong sense of duty.

A function that calls itself directly or indirectly again and again is called recursive functions and the process is termed as recursion. The most common example of a recursive function is the calculation of the factorial of a number. i.e., n! = (n) * (n – 1) Program:

void main()

{

int n;

int fact(int);

cout<<"Enter any number:";

cin>>n;

cout<<"The factorial is "<<fact(n);

}

int fact (int n)

{

int x;

if(n = = 0|| n = = 1)

return(1);

else

x = n*fact(n - 1);

return (x);

}

In the above example, the calling function main () gives the function call to fact () and control jumps from main () function to called function fact().

The argument ‘n’ value is compared with the base class ‘if (n == 1)’ if ‘true’ control will return back to calling function main() with the value 1.

If ‘False’, control will execute the statement which is after ‘else’ x = n * fact ( n – 1);. here a function call is given to fact (n-1) with the parameter (n-1).

Now the calling function is fact () and called function is also fact(). The recursion ends when value of ‘n’ is 1 then the statement return (1) is initiated.

The GROUP BY statement is used with aggregate functions (COUNT, MAX, MIN, SUM, AVG) to group the result-set by one or more columns.

The ORDER BY keyword is used to sort the result-set in ascending or descending order Example of Group By 

SELECT Dept No, COUNT(*) AS No of Teachers

FROM Teacher

GROUP BY Dept No;

Example of Order By

SELECT First Name, Last Name

FROM Teacher

ORDER BY First Name;

(i)  SELECT * FROM STORE ORDER BY LastBuy;

(ii)  SELECT ItemNo, Item FROM STORE WHERE Rate >15;

(iii)  SELECT * FROM STORE WHERE Scode = 22 OR Qty >110;

(iv)  SELECT Scode, MIN(Rate) FROM STORE GROUP BY Scode;

Numerical Abnormalities: When an individual is missing one of the chromosomes from a pair, the condition is called monosomy. When an individual has more than two chromosomes instead of a pair, the condition is called trisomy.

This pattern of necrosis is typically seen in hypoxic (low-oxygen) environments, such as infarction. Coagulative necrosis occurs primarily in tissues such as the kidney, heart and adrenal glands. Severe ischemia most commonly causes necrosis of this form.

An ideal suspension must possess the following properties:- 

• 1 It should settle slowly and should be readily re-dispersed on gentle shaking of the container. 
•  The particle size of the suspension remains fairly constant throughout its long period of undisturbed standing.

Undercasting means the total of a side has been totaled short. For example, the total of payments side of the Cash Book was Rs 12,000, however, it was found that it was undercasted by Rs 200. This means that the total of credit side (payments side) of the Cash Book was totaled less by Rs 200, the actual total should have been Rs 12,200 (12,000 + 200). 

Undercasting of Payments side means Cash Book balance will be more in comparison to the Pass Book Balance 

Reason : Balance of Cash Book = Receipts side - Payments side So, when payments are less (than actual), balance will be more. 

Thus, when the starting balance is balance as per Cash Book, it will be shown in the 'minus' column (to make Cash Book = Pass Book) 

When the starting balance is balance as per Pass Book, it will be shown in the 'plus' column (to make Pass Book = Cash Book)

fetchall() fetches all the rows of a query result. An empty list is returned if there is no record to fetch the cursor. 

fetchone() method returns one row or a single record at a time. It will return None if no more rows / records are available.
