The meaning of bit patterns is determined by the way the HW and SW treat them.
Answer: True
Explanation:
The meaning of bit pattern are determined by the hardware and software treat them as, different types of computer used different pattern of bit for the instruction because they all are potentially different so the bit pattern are determine accordingly to the function of hardware and the software of particular devices.Instruction are stored in the form of bits in the similar memory as the data. Bit pattern are used to communicate in the memory as the sequence of bits.
If a compiler detects a violation of language rules, it refuses to translate the class to ____.
a.
machine code
b.
a logic error
c.
an application
d.
Java
Answer:
The correct answer is a. Machine code
Explanation:
The syntax of a language is a set of rules that indicates how to write programs.
A compiler is a system that in most cases has to handle an incorrect entry. Especially in the early stages of creating a program.
Syntactic errors are those that occur at the time of writing the program in the high level programming language and that do not comply with the grammatical rules of said programming language. These errors are generally detected by the compiler itself, since it only translates programs that are ''well written''. Therefore, a program that contains syntactic errors can never be compiled.
In summary, syntax errors are detected in the process of translating source code into binary code. On the contrary that happens with the errors of execution and of logic, that can only be detected when the program in being executed.
Answer:
a. machine code
Explanation:
When we code a program, be it in C, C++, Java, etc,..., the role of the compiler is to translate our code to machine code, so it can be executed.
This only happens if we do not violate any of the language rules. Otherwise, there are going to be compilation errors and we will have to fix our code before it is compiled, that is, translated to machine code.
So the correct answer is:
a. machine code

A major advantage of a method is that it is easily reusable. What does it mean to reuse a method and what are the advantages of doing so?
Answer: To reuse a method means to use a code which has been done or prepared already and just we need to change some of the functionalities.
This helps a great deal of saving time as well as helps in making the code manageable.
Explanation:
This has been practiced since long that methods can be reused. for example we need to build a calculator in c. then we can simply reuse the same method just we need to change the sign of the operator. So in this process we can speed up our operations and work and also can make the code easy to understand and manage it when we have have to deal with large lines of code.
Final answer:
Reusing a method in programming allows for using the same code in multiple places efficiently and consistently, saving time and reducing the potential for errors. It's the easiest and least disruptive way to add functionality to programs and aligns with sustainable practices.
Explanation:
Reusing a method in programming means employing a piece of code that has already been written to perform a function or a task in multiple places throughout your application. This is akin to creating a tool that can be used repeatedly in different contexts without the need to rewrite the code each time.
Advantages of Reusing Methods:
Efficiency: Reusing methods is a quick and easier way to add functionality to your programs without rewriting code, saving time and effort.Consistency: It contributes to a more robust and error-free program as the method has been tested and debugged once, ensuring consistency across its applications.Implementing reusable methods is often the easiest and least disruptive way to enhance a program, aligning with the Process Reaction Method which emphasizes simplicity and minimal interruption.Well-designed functions and methods enhance the maintainability and scalability of software by allowing the same logic to be utilized in different parts of an application or even in different projects entirely. This reusability can lead to economic and environmental benefits, as it aligns with the principles of reduce, reusable, and recycle.

In open addressing as everything is stored in the same table.
The _________ statement causes a function to end immediately.
Answer:
return
Explanation:
return is the statement which is used to return the value from the function definition to the function calling.
it is also used as exit from the function.
for example:
int count()
{
return 0;
printf("hello");
}
In the above the function return 0 without print the message "hello". we can used return any where inside the function for immediately ending the execution of function.
Final answer:
The statement that causes a function to end immediately is the 'return' statement, which halts function execution and returns the flow of execution to where the function was called.
Explanation:
The statement that causes a function to end immediately in most programming languages is a return statement. When the return statement is executed, it ends the function execution and the flow of execution goes back to where the function was called, which can be likened to coming back from a 'detour'. It's important to realize that defining a function also creates a variable with the same name, which can be used to call the function later in the code.
A functional approach to programming includes various other concepts. For instance, to end the function, you have to enter an empty line in some interactive environments like REPLs (Read-Eval-Print Loop), although this is not necessary in a script. The last statement of a function plays a role similar to a 'Note of Finality' in a speech, indicating the end of the logic encapsulated by the function.

Which statement about images is correct? A) A virtual image cannot be formed on a screen. B) A virtual image cannot be viewed by the unaided eye. C) A virtual image cannot be photographed. D) Mirrors always produce real images.
Answer:
A) A virtual image cannot be formed on a screen.
Explanation:
A virtual image cannot be formed on a screen is correct about images.
A virtual image can be viewed by the unaided eye.
A virtual image can be photographed.
Mirrors don't always produce real images.
The correct statement about images is that a virtual image cannot be formed on a screen, as virtual images are created by diverging light rays. However, they can still be seen and photographed because devices like cameras and the human eye can focus these rays.
Explanation:The correct statement about images is A) A virtual image cannot be formed on a screen. Virtual images are formed when light rays diverge in front of a mirror or behind a lens, creating an image that appears to be located behind the mirror or lens. Unlike real images, which can be projected onto a screen because they are formed by converging light rays, virtual images are not formed at a point in space where a screen can capture them. However, virtual images can be seen by the unaided eye and can also be photographed, contrary to some misconceptions. This is because cameras and eyes can focus diverging rays to form an image.

What is internal recruitment ?
Answer:
The term ‘Internal Recruitment’ refers to the process of identifying and attracting candidates from a certain organization to another position within the same organization.
Instead of opening the position to the public and attracting random candidates some companies may choose to advertise the vacancy internally and only allow members of the staff to apply.
Internal recruitment also refers to a strategy mostly big corporations use to advertise their jobs internally. Due to the size of these companies, these job openings would otherwise go unnoticed by employees in other departments.
How to declare a structure of a linked list?
Answer:
struct Node{
int data;
struct Node *next;
};
Explanation:
Linked list is the data structure which is used to store the series data but not in continuous memory location .
Linked list contain node which store the data and pointer which store the address of next node. If their is no next node, then it store the NULL.
so, the structure must declare the data and a pointer variable.
What is the typical data transfer rate (in bps) over a SS7 transfer link?
Answer: 55 Kbits/sec - 64 KBits/sec
Explanation:
Signal System 7 (SS7) is used one of the protocols used for communication for mobile operators and it uses circuit switching. As it uses circuit switching it transfers data using a dedicated channel and hence more comparatively faster. It communicates and sends signals among Service Switching (SSPs), Signal Transfer Points (STPs), and Service Control Points (SCPs) using a different path apart from the data transfer path.
The data transfer rate which is the transfer of data among the various network elements is 55 Kilo bits/sec - 64 kilo bits/sec.
Can you comment on the advantages and disadvantages of having ARP responses implemented as broadcasts?
Answer:
The advantages of ARP implemented as broadcast is that it enables easy and faster transfer of messages in a network. The disadvantage of ARP is that many of the nodes in the network may update their ARP cache locally without forwarding it to other nodes.
Explanation:
Address resolution protocol(ARP) has both advantages and disadvantages when implemented as broadcast. Broadcast technology enables to transmit messges across all the nodes.
The advantages of ARP implemented as broadcast is that it enables easy and faster transfer of messages in a network. The disadvantage of ARP is that many of the nodes in the network may update their ARP cache locally without forwarding it to other nodes.

Write a program that lets the user guess the coin's head or tail. The program randomly generates an integer 0 or 1, which represents the head or the tail. The program prompts the user to enter a guess and reports whether the guess is correct or incorrect. include step by step commentary.
Answer:
#include <iostream>
#include <stdlib.h>
#include <time.h>
using namespace std;
int main()
{
srand (time(NULL)); //initialize random seed
int guess;
int number = rand() % 2; //generate random number 0 or 1
cout<<"Enter the guess (0 or 1): ";
cin>>guess; //store in guess
if(number == guess){ //check if number equal to guess
cout<<"Guess is correct."<<endl; //if true print correct message.
}else{
cout<<"Guess is incorrect."<<endl; //otherwise print correct message.
}
return 0;
}
Explanation:
first include the three library iostream for input/output, stdlib,h for using the rand() function and time for using the time() function.
create the main function and initialize the random number generation seed, then generate the random number using the function rand() from 0 to 1.

What is infix, prefix and postfixexpressions in data structures?
Explanation:
Infix notation: A+B
Operators are written in-between their operands. Expression X * ( Y + Z) / P is means: "First add Y and Z together, then multiply the result by X, then divide by P to give the final answer."
Postfix notation : A B +
Operands are written before their operators. Expression given above is equivalent to X Y Z + * P /
Operators evaluation is always left-to-right, we will not consider brackets for the order.
Prefix notation : + A B
Operands are written after their operators. Expression given above is equivalent to / * X + Y Z P
Operators evaluation is always right-to-left,we will not consider brackets for the order.
Write a for loop to print all NUM_VALS elements of array hourlyTemp. Separate elements with a comma and space. Ex: If hourlyTemp = {90, 92, 94, 95}, print: 90, 92, 94, 95 Your code's output should end with the last element, without a subsequent comma, space, or newline.
Answer:
#include <iostream>
using namespace std;
int main() {
int NUM_VALS;//variable NUM_VALS for the size of the array..
cout<<"Enter the size of the array"<<endl;
cin>>NUM_VALS;//taking input the size of the array..
int hourlyTemp[NUM_VALS]; //declaring array hourlyTemp of size n..
cout<<"Enter values of the array "<<endl;
for(int i=0;i<NUM_VALS;i++)
cin>>hourlyTemp[i];//taking input of hourlyTemp
for(int i=0;i<NUM_VALS;i++) //for loop for iterating over the array..
{
if(i!=NUM_VALS-1)
cout<<hourlyTemp[i]<<", ";// print statement.
else
cout<<hourlyTemp[i];//print statement.
}
return 0;
}
Explanation:
I have taken NUM_VALS variable for the size of the array hourlyTemp. First i am taking input the size of array form user and after that array elements are also entered by the user.I am iterating over the array using for loop and checking that it is not the last element if it is simply printing it if it is not then printing comma and space also.

______________ Gives the Mean time for which systemremained available for use.
a) MTTF
b) MTBF
c) MTTR
d) MTTD
Answer: d)MTTD
Explanation: MTTD(Mean Time To Detect) is the time for the discovery of the problem in a system. It is basically the average time until the problem is noticed by someone. For e.g.- if there is a problem in a computer system at 9:00 am and the problem is noticed at 9:10 am by then user then the MTTD is 10 minutes . So, MTTD gives the mean time for which the system remains available for use.

Why we called COBOL as a professional language and not ataught language
Answer:
COBOL(Common Business Oriented Language).As the name suggests it is most commonly used to develop business tools and hence it is called a professional language and it is not used in schools or colleges as a teaching tool like FORTAN hence it is not called a taught Language.
COBOL is also used to develop business applications.It is mainly designed for businesses.
The true or false questions.
The command: find . -type f -mtime +10 will search in the current directory and its subdirectories for all regular files that have not been modified in more than 10 minutes.
Answer:
False
Explanation:
The command find . -type f -mtime +10 will search for all files in the current directory and its subdirectories which have not been modified in more than 10 days.
-type argument specifies the type of entity to be searched which in this case corresponds to f (or file).
-mtime argument specifies the last modified time check for the files in terms of number of days and not number of minutes.
