Data Communication and Networking

Data communication is the exchange of data between two devices. Communication devices must be part of the communication system for data communication to occur. Hardware and software make up the data communication system.

Hardware and software both physical equipment. Data communication and networking is about being able to exchange data from one point to another. The signal from the transmission system is accepted by the receiver and converted into a form that is handled by the destination device.

Data Communication

Data communication is the exchange of data between a source and a receiver. If a device is in the same building or restricted geographical area, it is said to be local. The meanings of source and receiver are very simple.

The source and receiver of the data are known. Data communication is about the transfer of data and maintenance of data during the process but not the actual generation of information at the source and receiver. The facts information statistics are derived from calculation or experimentation.

The facts and information are processed according to the system of procedure. Data can be found in a variety of forms. The Figure is an example of a data communication system.

3. The device or computer that receives the message is the receiver. The sender computer is usually located in the same area as the receiver computer.

The sender and receiver are connected by a network. There are 4. Medium is the physical path through which a message is carried from sender to receiver.

Communications Data in a Digital Age

The text of an email or a conversation a telephone are not included in the data. Information about a communication is not the communication itself. Communications data has been used in 95 per cent of all serious organised crime investigations over the past decade.

It is important to law enforcement when dealing with organised crime gangs, paedophile rings and terrorist groups. It is used by the police and the security agencies in the investigation of crimes. It allows the police to build a picture of the activities of a person under investigation.

If the police can show that it is necessary in a criminal investigation, they can get access to communications data. Access is subject to oversight and is on a case by case basis. The police can't get access to communications data if they are not involved in a criminal investigation.

Communication service and technology are changing fast. More and more of the communication is done on the internet and less on the phone. Communications data is not collected and stored for some services.

Synchronous Transmission of Digital Signals

Digital signals allow for greater signal processing capability. Errors caused by random processes can be detected and corrected if the ability to process a communications signal is used. Digital signals can be monitored.

The multiplexing of multiple digital signals is much simpler than the multiplexing of analog signals. Synchronous transmission uses clock signals to sync transmission speeds at both ends. The clock may be in the data.

The Impact of Internet on Students' Academic Progress

Telecommunications is the transfer of data and information over distances. Data and software of computer can be shared with other computer on the network. The network can only be used by authorized users.

The internet can affect students by making them vulnerable to getting addicted to the internet. It was cheating. Homework and other school projects can be copied right off the internet, making it very easy to cheat.

Data Communications

A computer connected to the Internet via wireless connection can send and receive data from one or more remote server. To talk about different types of data communications is to refer to the functions that are available for the sender and receiver. You have simplex communications, which are only one-way data communications, and you have half-duplex and full-duplex data communications models.

The Convergence of Wireless Communications, Internet and E-Commerce

The call is translated from analog to digital when it reaches the first telephone switch. It is translated back to the original form to travel over the local loop to reach the destination. The convergence of wireless telecommunications, Internet, and e- commerce is related to the entertainment industry and household appliances. The directions of that evolution are not predictable.

The Rise of the Internet: A New Dimension for Human Society

Modern telecommunications rely on data communication, which is the transmission of digital data through a network or device outside of the sending device. Without the technological advancement of telephones, computers, the Internet and wireless technology, contemporary society would be vastly different.
