Transmission Impairment Different causes of Transmission impairment are as follows: Attenuation Any reduction in the strength of a signal is known as an attenuation and signal lost some of its strength when it is transmitted over transmission medium for long distance.It occurred in both guided and unguided transmission media.The signal loss in the energy in order to overcome the resistance of the transmission media.It carrying  an electric signal gets warm after sometime. some of the electrical energy in the signal is converted into heat.Amplifier is used to amplify the signal to recovered the loss of energy this process is known as amplification. Distortion The change in the form or shape of the signal is known as distortion.It can occur in a composite signal  that consists of different frequencies that each signal has its own propagation speed through a medium.Different signal the have different delayed in arriving at the distination.This difference may create a distortion i...

Programming language A set of word symbol and codes used to write program is called program language.Different programming language are available for writing different type of program that some languages are specially used for writing business programs and some are used for writing scientific programs.They are two types of computer programming language known as low level language and high level language. Types of computer programming language 1. low level language 2.  high level language   Low level language Low level languages are near to computer hardware and far from human languages. Computer can understand the language Writing a program in low level language is required are deep knowledge of the internet structure  like computer hardware.Two types of low level languages are machine language and assembly language. Machine Language A type of language in which instruction are written in binary form is called machine language.It is the only language that is directly under...

What is difference between data and information Data processing A process of converting data into meaningful information in call data processing that it is important information with the output of the data processing system that it is important but it cannot be used for decision making it must be converted into meaningful information in order to use it for making important decisions it convergence consists of different step which perform in a sequence. Example of data processing Student in the examination or store it as data expose a list of students a is required who got a grade in examination some processing will be applied on mark of the students this process will give new information in the form of desired list in this data processing the marks of students are the data and the list of students with a great is our information. . people deposit money in bank that is told as data in register are computer suppose the bank manager want to know the total amount deposit in the bank the to...
