What is digital data transmission?
Digital data transmission use voltage differences to directly represent the 1s and 0s that make up the data and are not modulated over a carrier.
What is often meant by the term 'data transmission'?
A transfer of data from point-to-point is simplified as data transmission. Data transmission can be referred to as digital communication but can include analog data transmission as well.
What is digital transmission of analog data?
it means that you digitize analog data for transmission . Like 2 computer that chatting .
What is a set of standards for digital transmission of data over standard copper telephone lines?
The set of standards for digital transmission of data over standard copper telephone lines is ISDN
What is tcp session?
A TCP session is a data transfer that takes place using the transmission control protocol. A session has three phases, connection establishment, data transmission, and connection termination.
Which connection type provides the fastest data transmission?
Fiber Optics
What is packet oriented data service?
A method of data transmission in which small blocks of data are transmitted rapidly over a channel dedicated to the connection only for the duration of the packet's transmission.
What is the rule for exchanging data between computers?
Depending on the system, more cases it is authentication. Usually done in a form of a digital handshake.
Advantages and disadvantages of digital transmission?
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.by Abdullahcu-516-Acecos university
What type of data transmission occurs in a computer bus?
A digital data transmission occurs in a computer bus. The data are in the form of electromagnetic signal, such as an electrical voltage, microwave, radiowave, or infrared signal.
Why would digital data have to be modulated onto an analog signal?
For transmission through a radiowave.
