synchronization between the multiplexer and demultiplexer is a major issue in data transmission. if the multiplexer and demultiplexer are out of synchronization a bit belonging to one channel may be received by the wrong channel. for dis reason , one or more synchronization bits are usually added to the beginning of each frame. these bits, called framing bit , follow a pattern, frame to frame, that allow the demultiplexer to syncronize with the incoming steam so that it can separate the time slots accurately. in most cases, this syncronization information consists of one bit
to secure analog data is called scrambling in data communication
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.
data communication terminologies ther are many people distribute about computer

The Global Data Synchronization Network is used by corporations to communicate data with each other. This allows for easy communication between companies that are partners that buy and sell goods from one another.
A second DNS server helps in synchronization of DNS data from primary to secondary.
In computer science, especially parallel computing, synchronization means the coordination of simultaneous threads or processes to complete a task in order to get correct runtime order and avoid unexpected race conditions. There are many types of synchronization: * barrier * lock/semaphore * non-blocking synchronization * synchronous communication operations advantages of synchronous communications are * no need of start and stop bits * higher data rates possible * the actual data length need not be fixed
In telecommunications and electronics, a self-clocking signal is one that can be decoded without the need for a separate clock-signal or other source of synchronization. This is usually done by including embedded synchronization information within the signal, and adding constraints on the coding of the data payload such that false synchronization can easily be detected.self-clocking-signal
The foremost problem that can occur is the "loss of data" due to interference or the data collision that causes corruption of data...
well first off, im not an expert. but for what i know its something like this. synchronization is like keeping access to shared data with locks. learning threads might be good for you to somewhat get a grasp of what synchronization is about.
the purpose of buses is to reduce the number of pathways needed for communicate between the components , by carrying out all communication over a single data channel. synchronization- synchronization between components can set with help of buses. buses are used for high speed transfer between CPU, memory and other devices .
Data synchronization is commonly used by your own home computer to backup its own data. This process can also be used to transfer downloaded content such as books, movies, and music to portable devices such as a tablet, television, or other portable devices.

Disadvantage of Analog Communication: 1)Analog Communication systems are costlier than digital communication system. 2)Less Security in Analog Communication 3)More prone to noise interference. Advantage of Analog Communication: 1)Transmission bandwidth required is less. 2)No need of synchronization. Advantage of Digital Communication: 1)Digital Communication systems are simpler and cheaper. 2)Using data encryption only permitted user are allowed to detect the transmitted data. 3)Since in Digital Communication, channel coding is used, therefore a large amount of errors may be detected 4)Since transmitted signal is digital in nature,large amount of noise tolerance may be tolerated Disadvantage of Digital Communication: 1)More transmission bandwidth required. 2)Digital Communication needs synchronization in case of synchronous modulation.
The scope of work and the educational requirements are the difference between data communication and data communication information.
