Basics Of COMPUTER NETWORK

-


◘ What Is A Network?

          A network is a group of two or more computer systems, which are linked together. It also consists of a collection of computers, printers, scanners and other devices that are connected together.

      Networking has single purpose to share the information as fast as possible.

 


◘ TYPES OF NETWORKS

                                               LAN

        LAN stands for local area network. It is used to network computers within a limited area like a office, school by using the network module.

                                               CAN

        Campus Area Network is an interconnection of local area networks within a limited geographical area. Campus network can be additional to the set of wireless connections, connect several buildings to the same network but it's not the same thing.

                                               MAN

        MAN means metropolitan area network, which optimized for a large geographic area than a LAN, ranging from several blocks of building to entire city.

                                               WAN

        WAN is wide area network that is a network connection of wide area such as the world.

Example: Internet

                                                PAN

        A personal area network (PAN) is the interconnection of information technology devices within the range of an individual person, typically within a range of 10 meters.



◘ BENEFITS OF NETWORKING 

      FILE SHARING: All types of data (audio, video, text and images) can be easily shared and exercised on network.

      INTERNET SHARING: A single internet connection can be shared with multiple users and devices.

      RESOURCES SHARING: Resources like scanners printer network data and applications can be accessed by remote connection devices using network connected devices. Example application can be shared by multiple users.

      INCREASING STORAGE CAPACITY:  Access any type of media file stored remotely on other computers storage devices.

OOP Concepts In Simple Terms

                                   CLASS           A class is a blueprint for creating objects (a particular data structure), providing initial values for state (member variables or attributes), and implementations of behavior (member functions or methods).                                                                                                  OBJECTS           Object is an instance of a class which has the structure of its blueprint but also owns its unique state and behavior.                                                                   ENCAPSULATION           Encapsulation is achieved when each object keeps its state private, inside a class. Other objects don't have access to this state.                                   ABSTRACTION           Abstraction means that each object should only expose a high-level mechanism for using it. This mechanism should hide internal implementation details.                                INHERITANCE             Inheritance is a m
