Telecommunications applications that support electronic commerce and business include electronic mail, groupware, voicemail, facsimile machines, digital information services, teleconferencing, videoconferencing, and electronic data interchange.

Electronic mail is the computer-to-computer exchange of messages. Groupware is a specialized form of teleconferencing and dataconferencing that allows individuals working in different locations to work together on common documents and projects. Voicemail is a system that digitizes spoken messages, transmits them over a network, and stores the message for later retrieval. The system includes a range of capabilities including saving messages and routing them to other parties. Facsimile machines transmit documents containing both text and graphics over ordinary telephone lines using a scanner to digitize the document.

Teleconferencing refers to the ability to confer with a group of people simultaneously using the telephone or electronic mail group communication software. Dataconferencing refers to teleconferencing in which two or more users are able to edit and modify data files simultaneously. Videoconferencing is teleconferencing that includes a video portion so that the individuals can actually see each other despite their distance.

Digital information services enable users to retrieve information, such as stock market data, periodicals, competitor data, legal research, and news articles, from outside the firm. Distance learning refers to education or training delivered over a distance to individuals in one or more locations. E-learning refers to instruction delivered online using the Internet or private networks. Electronic data interchange is the direct computer-to-computer exchange between two organizations of standard business transaction documents such as invoices or purchase orders.

The DNA segment 3' ATT 5' would be transcribed to the mRNA sequence 5' UAA 3'.

The word "telephone" comes from two Greek words, "tele" meaning distant and "phone" meaning sound or voice. When combined, it refers to a device that transmits sound over a distance, which is the basic function of a telephone.

I suppose you are questioning about major cellular/telephony and data networks. These networks are usually connected to their backbone by terrestrial connections mostly. In case of natural disasters, these connections got damaged. As a result, the network got disrupted.

DNA is similar to Morse code in that both are systems of communication using a sequence of symbols to convey information. In DNA, the sequence of nucleotides (A, C, T, G) contains genetic instructions for building proteins. In Morse code, the sequence of dots and dashes represents letters of the alphabet or numbers.

Morse Code provides a letter-based method of communication by means of any type of signal that can be switched on and off ... light, sound, etc. As such, it can accomodate messages in any language that uses the familiar Roman (English) alphabet. While using the simplest possible transmitting and receiving equipment, it is highly immune to noise, and can succeed over very noisy 'channels'.

They were invented in 1876 (before electric lights even!) and were quickly seen as interesting. Advances in technology resulting in longer distances calls being possible, coupled with the invention and spread of customer dialing equipment (rather than having to use operators for every call), greatly increased the telephone's usefulness and spread of technology in the early 20th century.

An analog-to-digital (AD) converter is needed in fiber optics communication to convert analog signals into digital format for processing and transmission. In digital fiber optic systems, signals are encoded as digital data bits for better noise immunity, signal integrity, and compatibility with digital processing equipment. The AD converter captures the analog signal and converts it into binary data that can be easily transmitted and interpreted in the digital domain.

The very basic principle adopted in optical fibre is the phenomenon of light known as total internal reflection. In case of ordinary reflection, there will be a chance of the light energy to escape through the reflecting surface. But in case of total internal reflection, even a bit of energy could not escape hence it is named as total internal reflection. Compared to the propagation of electromagnetic energy through space, passing through optical fibre would be without any loss and so the transmission efficiency becomes very high.

Before telephones, people either had to talk in person or write in order to contact other people. If you wanted a message to get to someone quickly , say to call the doctor, someone would have to go to the doctor's house or office to tell him he was needed.

In order to keep up socially, newspapers contained most personal news.

People called on each other more frequently .

In the cities, people would take strolls around the neighborhood in the evening or sit out on their porches and talk with passers-by. Mail was delivered twice a day and for 10 cents the post office would make a special delivery.

Archaeologists play a crucial role in preserving and interpreting our past, helping us understand where we come from and how human societies have evolved over time. They also contribute to protecting and conserving historical sites, artifacts, and cultural heritage for future generations to learn from and appreciate. Additionally, their research enhances our knowledge of diverse cultures and civilizations, fostering a deeper appreciation for our shared human history.

# Optical fibres can carry more information as opposed to conventional cables. # Optical fibres are not affected by radio frequency interferrence # Information carried in an optical fibre can only be tapped physically (to steal information, the thief has to work on the optical fibre so that the light will travel to the thief)

The electrical bandwidth refers to the frequency range that the electronic components in the communication system can handle, while optical bandwidth refers to the frequency range that the optical fiber can transmit. The relationship between the two bandwidths is important in ensuring that the data transmission is efficient and reliable. Matching the electrical and optical bandwidths helps to avoid signal degradation and distortion in the communication system.

The objectives of telecommunication companies typically include providing reliable and efficient communication services to customers, expanding their network coverage and capacity, investing in technology innovation, improving customer satisfaction, and achieving profitability and growth in the market.

Studying for an MSc in electronic media for 5 years can provide valuable knowledge and skills in the field. It allows for a deeper understanding of electronic media technologies, industry trends, and research methods. Additionally, having an advanced degree can enhance career opportunities and open doors to higher-level positions in the industry.

Sources provide information to reporters or editors. These sources can be individuals, organizations, or documents that have relevant and newsworthy information. It is important for reporters and editors to verify the credibility of their sources and the accuracy of the information provided.

Yes, Virgin Media uses the Nagra 3 encryption system to protect its cable television services. This system is designed to prevent unauthorized access to their channels and content by encrypting the signal.

There is a difference between the term media and mass media. Media has been around for ages. Mass media has only been defined since about the 1920s.

The first form of media would actually be recitation. Recitation predates printing and even writing. Recitation allowed large groups to gather to hear an individual speak and it allowed an individual to address large groups and even entire audiences. Many auditorium designs today are due to the engineering of the past that allowed the sound of the voice to travel more effectively. Over time, recitation maintained its power and effect in places such as theatre, education and debate. Aristotle himself created instruction, still used today to teach others how to use recitation as a tool for getting a message across to others effectively.

The term media was extended in the early 1900s to the term "mass media," which implied media outlets that could reach larger audiences faster. The term "media," however, goes back even further. Although mass media originally referred to printing and new visual outlets, these were not the first forms of media. Nor was this when newspaper, print and even visual were already impacting large audiences.

To write a functional description, outline the purpose of the system, its key features, and how it will meet user requirements. Provide clear and specific details on functionality, interfaces, data, and user interactions. Use diagrams or flowcharts to visually represent the system's processes and relationships. Be concise, precise, and use plain language for easy understanding.

As best as I could tell, he was let go due to SNR being penny wise and pound foolish. There goes my subscription.

They wear snazzy hats.

The media include forms of communication that reach a wide audience, such as television, radio, newspapers, and the Internet. These platforms are used to disseminate information, news, entertainment, and advertising to the public.

Some headlines from the 1930s included the Wall Street Crash in 1929 and the subsequent Great Depression, the rise of dictators like Hitler and Mussolini, the New Deal programs in the United States, the Hindenburg airship disaster, and events leading up to World War II.

The trial of John Peter Zenger in 1735 in colonial America helped establish the principle of freedom of the press. Zenger, a newspaper publisher, was accused of libel by the colonial governor, but the jury acquitted him, setting a precedent for protecting the rights of journalists to criticize government officials.
