The Von Neumann model is based on the concept of stored program where both of the program and instruction data are stored in the same electronic memory. Though it is still used in many models but due to the Von Neumann bottleneck we have the introduction of the secondary memory.

Answer:

Interrupt is defined as, in computer system interrupts are the signal sent to the central processing unit by the external devices. The main function of interrupt is that, an operating system that provide multiprocessing and multitasking. The interrupt is a signal that causes the operating system to stop work on one processor and started work on another processor.

There are basically two type of interrupts:

Answer:

UML - Unified Model Language

Explanation:

Use case diagram:

A use case diagram is used to tell how many ways a   user can interact with  a system. We use special   symbols and connectors to build use case   diagrams.  

We use  horizontal shaped ovals to represent use   cases, stick figures to represent actors, lines to   represent associations between use cases and  

actors, packages to put elements into  groups.  

Use case description:  

By the name itself, we can say that it is used to   describe the activities of user that  he can do with   the system and how the system responds to those.  Before use case diagram created, we need to write   a use case description.  

Class diagram:  

UML diagrams are of two types. They are,  

A class diagram comes under Structural UML   diagrams.

Classes are building blocks of an application that   uses OOPs concepts. Class diagrams are used to   represent classes, relationships, association,  

interface.  

Sequence diagram:  

A sequence diagram comes under  Behavioral UML   diagrams.It is used to tell the sequential order of   objects' interaction.We have many notations in this   diagram like actors, lifeline, create message, delete   message, lost message, found message etc. It is   used to tell how messages move between objects in   a system.  

Domain model :  

A domain model is a visual representation of real-  situation objects. In UML,  the Domain Model is   illustrated with a set of class diagrams

A Java program can calculate an employee's net pay by deducting federal, state, Social Security, Medicare/Medicaid taxes, pension plan contributions, and health insurance costs from the gross pay. The net pay is then output as the amount the employee would receive in their paycheck.

Explanation:

To calculate the net pay for an employee after deductions, we need to write a Java program that considers the following deductions: Federal Income Tax at 15%, State Tax at 3.5%, Social Security Tax at 5.75%, Medicare/Medicaid Tax at 2.75%, a pension plan deduction at 5%, and a fixed amount for health insurance at $75.00.

Here is a simple example of how this Java program might look:

public class PaycheckCalculator {
   public static void main(String[] args) {
       double grossPay = 5000; // Example gross pay
       double federalTax = grossPay * 0.15;
       double stateTax = grossPay * 0.035;
       double socialSecurityTax = grossPay * 0.0575;
       double medicareTax = grossPay * 0.0275;
       double pensionPlan = grossPay * 0.05;
       double healthInsurance = 75;

       double netPay = grossPay - (federalTax + stateTax + socialSecurityTax + medicareTax + pensionPlan + healthInsurance);

       System.out.println("Net pay: $" + netPay);
   }
}

This program calculates each of the deductions based on the gross pay, subtracts them from the gross pay, and prints out the resulting net pay.

A spreadsheet is a collection of data organized into rows and columns. However, it has limitations compared to relational databases in terms of data organization and accessibility.

A spreadsheet is a collection of data that is organized into rows and columns. Each column represents a field or attribute, while each row represents a record or data instance. While spreadsheets can function as a type of database, they have limitations in terms of data organization and accessibility compared to relational databases which use a tabular structure and allow for easier reorganization and access of data.

Answer: An objective function in linear programming is a decision variable.

Explanation: An objective function is a function which has the target towards the model whether it should be maximized or minimized according to the relation between the  variables present in the function. There are set of variables which are responsible for the controlling of objective function that is known as decision variables.

Answer:

Explained

Explanation:

Fields: Fields represent data and should be a noun. It should begin with a lower case letter.

Instance variable: it is a variable defined in class but outside the constructor and the method. instance variables are created when an object is instantiated.

Object: An object is the basic unit of object oriented programming language.and represents the real life entities. An object consists of state behavior and properties.

Method: Method in a collection of statements that perform some specific task and return the result to the caller.

Explanation:

Ping

TraceRoute

Answer:

In serial communication transfers one bit of data at a time, while parallel communication transfers many bits of data at the same time. Serial communication transmits the data bits sequentially, while parallel communication transmits data bits simultaneously, allowing greater amounts of data to be transferred.

-Serial communication is the one used to communicate the Arduino with the Computer through the USB cable.

-An example of a parallel port is the printer port. The Parallel Port was only created and used in the printers interface and the computers.

Explanation:

In serial communication, each bit is sent by its own clock flank where conditions are defined after each byte, if it is synchronous or asynchronous. In parallel communication there is only one single clock flank where the information is sent where it is an advantage to use it where there are several input or output data.

Answer: C) algorithm it uses

Explanation: The operation signature has the name of operation ,objects that it accepts and the value returned by the operation but it does not have algorithm that it uses.As algorithm defines all the steps that are to be used to find the result so signature operation does not include the whole algorithm that is to be used. The signature operation verifies the steps of the algorithm in way.

Answer:

Cache memory is relatively small in size as compared to the main memory. The cache memory stores programs, variables which are frequently used by the processor.

Explanation:

The cache memory is placed very close to the processor so that the programs and variables can be accessed very quickly as and when required by the processor. The size of the cache memory is small and also cost more. There is also a secondary cache in many systems which enables to store more programs which cannot be store in the primary cache.

// c++ code to read the recieved calls

cout<< " Enter the calls recieved :";

cin>>callsRecieved;

cout<< " Enter operator on call : ";

cin>>operatorsOnCall;

// calculating the call per operator

calls_per_operator = callsRecieved/operatorsOnCall;

// printing the vaule.

cout<<" Calls recieved per operator are : " << calls_per_operator <<endl;

Final answer:

To find the number of calls received per operator, read inputs for callsReceived and operatorsOnCall, then divide callsReceived by operatorsOnCall using integer division and print the result.

Explanation:

To calculate the number of calls received per operator, you will first need to read values into the variables callsReceived and operatorsOnCall. You can do this using an input method appropriate for the programming language you're using (e.g., scanf in C, cin in C++, or input() in Python). Once you have these values, you perform the division of callsReceived by operatorsOnCall and print the result. Here is an example code snippet in Python:

Note that integer division with truncation is used (// in Python) to get an integer result.

Answer:

true

Explanation:

Answer:

In broadcast the message is transmitted from one to all , in uni cast we have one to one transmission and in multicast we have transmission from one to many.

Explanation:

If we take the example of a simple messaging application it will be clear. If a message is exchanged between one person to another, then it is uni casting. If a person sends a message to all the persons in his contact list then it is broadcasting and  if a person sends messages to select persons in his contact list then it is multi casting. In multi casting management of the group is required regarding who can receive messages which is not required in broadcasting.

Answer:

True

Explanation:

The bias value present in a floating point number deals with the positiveness and negativeness of the exponent part for a floating point number.  The bias value for a floating point number is 127. It means that 127 is always needed to be added to the exponent part of any floating point number.

In a single precision floating point number, we need 8 bits to store the exponent. Rather than storing it as a signed two's complement number, it is easier to simply add 127 to the exponent (because the lowest value that can be in 8 bit signed is -127) and simply store it as an unsigned number. If the stored value is bigger than the bias then it would mean the value of the exponent is positive otherwise it is negative, but if they are equal then it is 0.

Answer: A method without body is called abstract method. A abstract method can be called from a non abstract  class or method provided it is inherited using a subclass.

Explanation:

An abstract method is a method which does not have a body, it just has opening and closing curly braces. A class having an abstract method is also declared as abstract class. We cannot make an object of the abstract class.

example : public abstract float multiply(float x, float y);

is an example of abstract method.

calling an abstract method from a non  abstract method is possible provided it is inherited by a non abstract subclass.

Answer: Cli(Clear interrupt flag ) and sti(set interrupt flag) instructions are used for clearing the flag and setting or enabling a flag respectively while hooking an interrupt.

Explanation: During the action of hooking an interrupt,there are certain interruptions while changing of real time interrupt vector and to avoid those interruptions two instructions are used that is cli ans sli. Cli is present for the clearing or disabling the interrupt flag and sti is used for setting or enabling a interrupt flag.

Answer: Classification of computer software are:-

Explanation:

Answer:

TRUE

Explanation:

The array is allow to store the multiple values but with same data type.

It cannot store element with different data type.

For example:

int array[] = {1, 'b', 8.7, 9, 'z'}

the above is wrong way to declare the array.

the correct ways is:

int array[] = {1,2,3,4};

float array[] = {1.2, 3.4, 9.6};

we can store only same data type element in multiple tiles.

Answer:

  see attachment

Explanation:

You have not specified the language, or the details of the I/O form or prompts. Here is a program that does that, written in Wolfram language (the language of Mathematica).

It prompts separately for student name and student score. The minimum score is presumed to be higher than -99999. If only one student name is entered, the second output is that score with no name listed. There is no error checking.

We have elected to keep a list only of the two two scores, and to sort that list again each time a new entry is made.

Answer:- Major property of a good hash code is that objects which are equal should return the same hash code .

Explanation: Hash codes is a numeric value which  is used for identify a object while a equality testing .Hash code can occupy the value of any length and then returns a fixed length value. The value of hash codes are variable.

If two objects are equal then by the method of equal(object) if the hashcode() function is called on both the objects , they produce the same value.

Answer: Option A) De facto standard

Non proprietary standard is also termed as de facto standard.

Explanation:  Non proprietary standard is also termed as de facto as when the proprietary standard such as window are widely used, then it becomes  de facto standard. When de facto standard is referring in terms of computers, it is an accepted application, design or language standard that is used in industry but not officially recognized.  

An example of de facto standard is paper clip ion used in e-mail to represent an attachment.
