If you want to know error detection techniques then this video will solve your query.

This is a part of lecture presented by Ms.Rashmi Sharma Asst. Professor of Biyani Girls College. The video is about Stack Data Structure. Stack data structure is one of the most useful concepts in computer science. Stack is a data storage structure (Abstract data type). Unlike, arrays access of elements in a stack is restricted. It has two basic operations push and pop for insertion of an element and deletion of an element. The video is helpful for BCA, MCA, and M.Sc. (IT) Students.

Java is a difficult language but we make it easy to understand.

In Object Oriented programming the emphasis is on data rather than on procedure. Programs are divided into objects , Data is hidden and can’t be accessed by external design. The main concept are .
• Object:- Objects are identified by its unique name. An object represents a particular instance of a class. There can be more than one instance of a class.
• Class:- Class a blueprint for an object. This doesn’t actually define any data, but it does define what the class name means, that is, what an object of the class will consist of and what operations can be performed on such an object. No memory is allocated when a class is created.
• Data Encapsulation:- Data Encapsulation combines data and functions into a single unit called Class. Data Encapsulation enables the important concept of data hiding possible.
• Data Abstraction:- Data abstraction refers to, providing only essential information and hiding their background details .
• Inheritance:- Inheritance is the process of forming a new class from an existing class that is from the existing class called as base class, new class is formed called as derived class.
• Polymorphism:- The ability to use an operator or function in different ways in other words giving different meaning or functions to the operators or functions is called polymorphism.

In this Video, Karuna Yadav, Biyani Group of Colleges, explains about the shortest job first preemptive algorithm work. In this processes are scheduled according the arrival time.

This is part of lecture presented by Dr. Madhu Sharma, Head of the Department (MCA) in Biyani Institute of Science and Management. This lecture is about — Basics Concepts of Artificial Intelligence. It involves the definition of Artificial Intelligence and introduction of Philosophy, Psychology, Mathematics and Linguistics as the base subjects along with the four different view of Artificial Intelligence-thinking humanly, acting humanly, thinking rationally and acting rationally.

Encapsulation: Encapsulation means binding data Members and methods into a single unit with data Security. Encapsulation is used for Security purpose. Polymorphism: polymorphism means one thing performs different actions depending on Situation. Method overloading is a way to achieve polymorphism.

The Video is all about the Management information system. This video describes the flow of information in the organization.MIS is planned system of controlling and storing in the form of information.

OSI is a seven layered architecture used to establish communication between 2 systems which have nothing in common like they are in different networks, having different hardware and software, having different internal architectures. Those seven layers are: physical , datalink, network, transport, session, presentation and application. Each lower layer provides its functionality to the layer above it.
