1. The signal is exact. For example, Digital formats like PCM (Pulse Code Modulation) can hold the exact digital format of sounds.
2. Digital signals can checked for errors. Generally, all digital transmission methods use 'head labels' to provide better checking facilities. Head label may contain how many packets may need to complete the transmission, what is the sequence number of each packet of data, acknowledgment labels etc.
3. A variety of services can afford over one line. For example, IpTV connection can used to watch cable TV channels while browsing the internet through a PC using same line. This line can also used to make a phone call at the same time.
4. Digital data can be compressed and therefore possible to pass over higher bandwidths. Any digital data; data, image, video, voice can be compressed.
5. More secure. Digital data can be encrypt using an encryption method. Only the dedicated receiver can decode the message.
6. Supports data integrity. Simple to integrate voice, video and data. Digital transmission provides easier way to integrate different digital formats.
7. Digital transmission provides higher maximum transmission rates via medium such as optical fibers. Typically, digital transmissions use less bandwidth.
Disadvantages::::::::
1) digital equipment costs more and is much more complex.

advantages, disadvantages of digital control systems
Advantages: It's digital. Disavantages: It's not analogue.
distorted data
advantages: more reliable easy to minipulate compatibility with other digital systems disadvantages: sampling error
The advantages of transmission media are it is easy to terminate, cheap cost of installation, and the high installed base. The disadvantages are the noise, they cover less distance, and may suffer interference.

advantages of guide transmission media
Advantages: Secure transmission of documents. Legal acceptance in certain industries and for official documents. No need for internet connection for transmission. Disadvantages: Limited quality of document transmission. Slow transmission speed. Issues with paper jams and maintenance.
Easy to manipulate. Compact storage. (those are also the disadvantages)
One advantage for parallel transmission is the speed that the data can travel at, while one disadvantage for parallel transmission is the high cost of it
There are no dis-advantages, it is a new generation of technology. It allows transmission to shift in order to make car go the most distance with least amount of fuel.
