difference between circuitswitching andpacket switching

Circuit and packet switching technologies accommodate the transmission of data, such as from a mobile phone to a wireless network, and vice versa. These two technologies use different methods to achieve their shared objective and are used by a variety of devices, including cellphones and computers. Generally speaking, circuit-switching protocols are faster, but packet-switching protocols are more efficient.

Circuit-Switching

  • With circuit-switching technology, a single circuit, or channel, is secured for an entire data transmission session. Circuit-switching protocols are most commonly found in telephone systems and provide an uninterrupted connection for each phone call. These types of connections are designed for instances that require real-time data transmissions. Circuit-switching protocols provide faster transmissions than packet-switching protocols and are best used in situations where the transmitted data must arrive in the same order it is sent. These types of connections take place on what is known as a connection-oriented network.
  • path must be decided before data transmission starts;
  • completion of transmission can be faster because less
    overhead is used for routing data units;
  • if the connection breaks so does transmission of data

Introduction to Object Oriented Programming ( OOP )

Object-Oriented Programming Object Oriented programming is a programing model that is based upon data and object. Classes   Classes are the blueprint of objects. Now you will think about what actually blueprints are. Blueprints are actually a design or plan to build something. Let's take an example like the map is detail plan of house classes are detail plan in  Object-Oriented programming. let's give you an example of a class on java so that you can unferstand. public class Car {          int horsePower;     String name;     String color;      String Company; } public class Sample {     public static void main(String[] args) {         Car car;         Car mehran;             } } Class name always start with capital letters . It is a good practice to name classes .  We will later learn how this is good. So in the above class Car ...

Types of Computer Networks(LAN,MAN,WAN)

Types of Computer Networks Computer networks are categorized according to: How they are organized physically. The way they are used. The distance over which they operate. Three main types of computer networks are as follows: LAN   (Local Area Network) WAN (Wide Area Network) MAN ( Metropolitan-Area Network) LAN (Local Area Network) LAN is the most common type of network . LAN stands for Local area Network . It covers a small area. Most LANs are used to connect computers in a single building or group of buildings. Hundreds or thousands of computer maybe connected through LAN. Typical LANs can be found in industrial plants, office buildings, and college or university campuses. LANs are capable of transmitting data at very fast rate. Data transmission speeds of LAN are 1 to 100 megabits per second. It is much faster than data transmission over a telephone line. LAN can transmit data in a limited distance. There is also a limit on the number of...

Computer Buses

Computer Buses   A computer system consists of different devices.CPU must be able to communicate with all devices. The devices are connected together by a communications channel called bus. A bus consists of a set of communication lines or wires. It is used to move a large amount of bits in the form of electrical pulses from one unit to another. The bus is used to connect the following units: Central Processing Unit Control Unit  Arithmetic and Logic Unit Main Memory ( RAM, ROM) Input / Output Devices Bus is a common path to transfer data and commands between CPU, memory and input / output devices.It is also used to send or receive data from secondary storage.The capacity of a bus depends on the number of data lines in it.A bus with 16 lines can carry 16 bits or 2 bytes at a time. A bus with 32 lines can carry 32 bits or 4 bytes at a time . Types Of  Buses Different types of buses are as follows: 1. Data Bus 2.Addres...
