What are the basic operations performed in stack?
Stack is a linear data structure which follows a particular order in which the operations are performed. The order may be LIFO (Last In First Out) or FILO (First In Last Out). Mainly the following three basic operations are performed in the stack: Push: Adds an item in the stack. If the stack is full, then it is said to be an Overflow condition.
What is stack data structure?
Stack Data Structure (Introduction and Program) Stack is a linear data structure which follows a particular order in which the operations are performed. The order may be LIFO(Last In First Out) or FILO(First In Last Out). Mainly the following three basic operations are performed in the stack:
What is the difference between LIFO and FIFO?
Making it a last in, first out data structure - LIFO. A queue has a first in, first out data structure - FIFO. Like someone standing in line or waiting in a queue. The person who is first in the line, gets seen first. to add or remove something from the end of an array, this process follows the LIFO order.
What is the last in first out Order of a stack?
A stack has a last in, first out order - LIFO. They are stacked one on top of the other. To get to the cookie second from top, you would have to remove the first one. Making it a last in, first out data structure - LIFO. A queue has a first in, first out data structure - FIFO.
Which of the following is managed in a FIFO manner?
A queue is managed in a FIFO manner. 7.
Which of the following represents a set of unambiguous instructions for solving a problem in a finite amount of time using a finite set of data?
What is an algorithm? A set of unambiguous instructions for solving a problem in a finite amount of time using a finite amount of data.
Which of the following allows a language to have duplicate method names and to apply the method that is appropriate for a particular object?
PolymorphismPolymorphism is the ability of a language to have duplicate method names in an inheritance hierarchy and to apply the method that is appropriate for the object to which the method is applied.
Which of the following is a device for converting an analog signal to a digital signal and back again?
A modem is a device that translates digital signals from a computer into analog form so that they can be transmitted over analog telephone lines. The modem also translates analog signals back into digital form for the receiving computer.
What is called as a sequence of unambiguous instructions for solving a problem?
An algorithm is a sequence of unambiguous instructions for solving a problem, i.e., for obtaining a required output for any legitimate input in a finite amount of time.
Is a sequence of unambiguous finite and ordered instructions to be followed to solve a problem?
1) An algorithm is a sequence of unambiguous instructions for solving a problem (i.e., for obtaining a required output for any legitimate input in an infinite amount of time).
What translates and executes program statements in sequence instead of having separate translation and execution steps?
A compiler translates a high-level language program into the corresponding program in machine code.
Which of the following is the process of creating an object from a class?
The process of creating an object is called Instantiation.
What is the object oriented programming system?
Object-oriented programming (OOP) is a computer programming model that organizes software design around data, or objects, rather than functions and logic. An object can be defined as a data field that has unique attributes and behavior.
What is the communication device that converts digital signals into analog signals and analog signals into digital?
modemmodem, (from “modulator/demodulator”), any of a class of electronic devices that convert digital data signals into modulated analog signals suitable for transmission over analog telecommunications circuits.
Which converts analog-to-digital and digital-to-analog?
An analog-to-digital converter, or ADC, performs the former task while a digital-to-analog converter, or DAC, performs the latter. A DAC, on the other hand, inputs a binary number and outputs an analog voltage or current signal.
What is the name of a device that converts digital signals to analog signals Mcq?
ModemModem used to converts digital signals to analog signals. It enables a computer to transmit data.
