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

Pointers in C

Pointers are an extremely powerful programming tool. They can make some things much easier, help improve your program's efficiency, and even allow you to handle unlimited amounts of data. For example, using pointers is one way to have a function modify a variable passed to it. It is also possible to use pointers to dynamically allocate memory, which means that you can write programs that can handle nearly unlimited amounts of data on the fly--you don't need to know, when you write the program, how much memory you need. Wow, that's kind of cool. Actually, it's very cool, as we'll see in some of the next tutorials. For now, let's just get a basic handle on what pointers are and how you use them. What are pointers? Why should you care? Pointers are aptly name: they "point" to locations in memory. Think of a row of safety deposit boxes of various sizes at a local bank. Each safety deposit box will have a number associated with it so that you ca...

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...

Ring topologies

Ring topologies are similar to bus topologies, except they transmit in one direction only from station to station. Typically, a ring architecture will use separate physical ports and wires for transmit and receive. Token Ring is one example of a network technology that uses a ring topology.
