Ans: The components of a computer system are:
CPU (Central Processing Unit) including control unit and arithmetic logical unit
Memory like primary and secondary.
Input and output devices like keyboard mouse, printer scanner, etc.
10) What is machine learning?
Ans: Machine Learning is a system that can learn from an excellent example through self-improvement and without being explicitly coded by a programmer.
11) What is deep learning?
Ans: Deep learning is computer software that mimics the network of neurons in a brain. It is a subset of machine learning and is called deep learning because it makes use of deep neural networks.
12) List out different OOPS principles?
Ans: The basic OOPS principle are: 1) encapsulation, 2) abstraction, 3) inheritance and 4) polymorphism.
13) What is a programming language?
Ans: A programming language is a collection of grammar rules to instruct computers or computing devices to perform tasks.
14) What is inheritance?
Ans: Inheritance is an object-oriented programming concept in which one class derives the properties of the rest of the classes.
15) What is a microprocessor?
Ans: A microprocessor is an integrated circuit having all the functionality of a central processing unit of a PC.
16) List out some computer processors
Ans: Computer processors are: 1) Intel Core i9, 2) Intel Core i5, 3) Intel Core i7, 4) AMD Ryzen 7, and
17) AMD Ryzen 5.
Ans: Primis Player Placeholder
18) List out some popular operating system
Ans: Some popular operating systems are Microsoft Windows, OSX, and Linux.
19) What Is A Super-class?
Ans: A super class is the basis of all the classes. The object of the rest of the class has all the characteristics related to the superclass.
20) Explain class variable
Ans: Variables represent a memory of class, which it shares with each and every instance.
21) What is SDLC?
Ans: SDLC stands for Software Development Life Cycle is a process that produces quality software products in less time. The stages involve by SDLC are: 1) planning, 2) design, 4) construction, 5) testing, and 6) deployment.
22) Explain the meaning of file.
Ans: A file is a named location that stores information or data permanently. It is always stored in the storage device using a file name with primary and secondary name, which is separated by a "."(DOT).
23) What is a programming language?
Ans: A programming language is a collection of grammar rules for giving instructions to computer or computing devices in order to perform achieve task.
24) What is Integrated Development Environment?
Ans: An IDE is a GUI-based software program. It is designed to help programmers build applications with all the needed programs and libraries.
25) Explain the framework
Ans: The framework is a platform for making software applications. It provides the basis on which developers can build programs for a specific platform. For example, a framework may include predetermined classes as well as functions. It can be used to process inputs, manage hardware, and interact with system software.
26 What is an Interface?
Ans: The interface is similar to a class in Java, but it is a collection of abstract methods. A class can have more than one interface.
27) What is a class?
Ans: A class is a blueprint for creating objects. A class contains methods and variables which are a class instance.
28) What Is Inheritance?
Ans: Inheritance is property such that a parent (or super) class passes the characteristics of itself to children (or sub) classes that are derived from it. The sub-class has the option of modifying these characteristics in order to make a different but fundamentally related class from the super-class.
29) To What Does Message Protocol Refer?
Ans: An object’s message protocol is the exact form of the set of messages to which the object can respond.
30) What is an abstract class?
Ans: A class having an abstract keyword is called an abstract class.
31) What is an array?
Ans: An array is a container that keeps a specific number of similar data types.
32) What is a constructor?
Ans: A constructor is a method that is used to create a class object.
33) Define Cin and Cout
Ans: Cin and Cout are objects used for input and output files, respectively.
34) List the types of constructors
Ans: There are two types of the constructor: 1) parameterized constructor and 2) default constructor.
35) What is artificial intelligence?
Ans: Artificial Intelligence or machine intelligence is a common term that is used to build smart machines capable of performing tasks. The main aim of AI is to solve problems in a way that are better and faster.
36) What is bye stream?
Ans: Byte stream is most usually used to perform input and output for Unicode having 8 bits.
37) What do you mean by destructor?
Ans: Destructor is a class member function that deletes or destructs an object.
38) List out Layers of OSI Model
Ans: Layers of OSI models are: 1) Physical, 2) Application, 3) Presentation, 4) Session, 5) Transport, 6) Network, and 6) Data Link Layer.
39) What is s the primary difference between process and thread?
Ans: Process is called as a program which is in execution. Thread is a segment of a process, so; a process can have more than one thread.
40) Explain primary memory
Ans: Primary memory, RAM is the main memory of a computer which can be directly accessed by the Central Processing Unit (CPU). It stores temporary information until the process finishes its execution.
41) What is the internet?
Ans: The internet is a global network of a computer that offers a wide range of information and communication facility. It involves interconnected networks, using a communication protocol.
42) What Is A Super-class?
Ans: Given a class, a super-class is the basis of the class under consideration. The given class is defined as a subset (in some respects) of the super-class. Objects of the given class potentially posses all the characteristics belonging to objects of the super-class.
