A. Noisy Channel:
Defines theoretical maximum bit rate for Noisy Channel:
Capacity=Bandwidth X log2(1+SNR)
Noiseless Channel:
Defines theoretical maximum bit rate for Noiseless Channel:
Bit Rate=2 X Bandwidth X log2L
Via data communication channels called data buses and the motherboard.
2H Log Base 2 v H is the bandwidth V = discreate levels
Madio communication refers to the means of delivering and receiving data or information to a large number of people. In telecommunication, these means are transmission and storage tools or channels for data storage and transmission.
It is simply a network of computers connected together by different communication channels that allow sharing of data and information.
Data transmission is the transfer of data from point-to-point often represented as an electro-magnetic signal over a physical point-to-point or point-to-multipoint communication channel. Examples of such channels are copper wires, optical fibers, wireless communication channels, and storage media. The term usually refers to digital communications (i.e. digital bit stream), but may include analog data transmission as well. Data transmission is a subset of the field of data communications, which also includes computer networking or computer communication applications and networking protocols, for example routing and switching.
Various media are used for data communication. Communication media refers to the means of delivering and receiving data or information. In telecommunication, these means are transmission and storage tools or channels for data storage and transmission.
The scope of work and the educational requirements are the difference between data communication and data communication information.
data communication link
to secure analog data is called scrambling in data communication
They are both forms of communication They are both a form of communication; data communication is a subset of telecommunication, telecommunication send data between two links by means of electromagnetic. (Like satellite), while data communication means send data by telecommunication, it consists of codes of 0's and 1's. In computer means, Data communication is digital data and telecommunication is equipped to send digital data to receiver.
In digital communication we talk about signal while in data communication we talk about data and the could be in the form of packets or frames.
