Circuit Switching

Circuit Switching is the simplest way in which Computer-to-Computer communication is achieved. The basic elements of Circuit Switching are:

( A ) Computers or Nodes

( B ) Communication Line

Data transmitted by a Computer is carried over the Communication Lines. Communication Lines deliver  transmitted data to the receiver ( a Computer).

Once a Computer is ready to transmit data, a Communication Line is established. This Line connects the transmitter  to the receiver.

_________________________

//Data Directed by Digital Transmitter//

//Travel Swiftly to Thankful  Receiver//

_________________________

Now, the actual communication begins. The data to be transmitted is divided into Blocks. The Transmitter sends the Blocks on a Communication Line. The Blocks are sent in order. 

_____________________________

//Data Sent Block by Block//

//Receiver Is the Place to Flock//

_____________________________

When all Blocks reach the receiver, the Communication Line  is released. The Communication Line  was established and reserved before starting the transmission. The reserved Communication Line was used for data transfer.

_______________________

//Communication Lines, Long & Fine//

//Errors Not Allowed to Shine//

_______________________

At any moment during transmission Circuit Switching clearly remembers:

( A ) The previously sent data

( B ) Data which is on the way

( C ) The data that is to be sent next

__________________________

Thus, we can say that Circuit Switching is able to remember the content related to communication. So, Circuit Switching is a stateful technique. The state of communication can be clearly expressed. In other words, information about transfer of data can be maintained using Circuit Switching.

Remarkable control over flow of data can be achieved using Circuit Switching. Controlled flow helps to ensure ordered delivery. We can say that data arrives at the receiver in the order in which it was sent.

//Circuit Switching, a Bit Slow//

//Focus Here Is Controlled Flow//

Due to tight control over transmission, Error Management is simple. Error correction can be easily done. Retransmission can be performed if transmission is somehow unsuccessful.

Local-Area Networks

Local-Area Networks ( LANs ) are restricted to a small area. Such Networks may be established within a building. Computers that are part of Local-Area Networks are Personal Computers ( PCs ) or microcomputers. These Computers are connected to each other. Simple communication lines connect these Pers Networks bring people together. When people join  hands teamwork becomes possible. The structural composition of LANs simplifies teamwork. In other words, LAN hardware supports teams having similar processing requirements. LAN Computers readily support personalization of tasks allocated to professionals.  Office staff can work together and share information. This improves the efficiency of the entire workforce. It has been noted that here all the Networked Computers are Personal Computers. They are of equal capacity. Mostly LAN users have similar tasks. If situations allow, a user is independent to access any Computer to serve his purpose. LAN users can exercise the option of secu...

Computers - An Introduction

Computers are man made machines. They are made to work very fast. Working fast they can solve  big and small problems.  Modern science has given us these computers. They are very popular. Computers affect and change lives. They keep us happy.The happiness grows. Computers are quick and smart. Great problem solvers and simplifiers are our computers. They can do our work without stopping. Focus is on doing only what is needed. Not needed, not done.  Computers are  life-less servants. They cannot think or make decisions on their own. They are empowered to work. They are given each and every thing so that they carry out our orders. Orders are respected by computers. The manner in which computers work is wholly dependent on man.  The quality of service provided by computers is remarkable. They are loved by human beings. Computers are known for smart and quick service. Computers do not give wrong results. Correct answers are always given. Questions which are difficult...

Euclid's Algorithm

The Greatest Common Divisor ( GCD ) of  two numbers is a number. The number ( GCD ) causes division of the two numbers. This number ( GCD ) is the greatest number that is possible. This divisor partially forms the two numbers. Adding  the divisor successively may result in formation of the two numbers. One can note that when the divisor is the greatest, the division of the dividend is the sharpest. The division operation is very effective. When the Greatest Common Divisor of two numbers is considered, we think of a number that can cause division of both the numbers. Here the two numbers are unequal. The Greatest Common Divisor causes divisions of the two numbers differently. This is clear from the two different quotient values.  The GCD value is very interesting to note. It relates very well with the two numbers. The GCD of two even numbers is also an even number. The GCD of two odd numbers is an odd number. So, we can say that GCD is an abstraction of the two numbers in ...
