...Has digital communication been a blessing or a curse to young people? Young people, mainly secondary school students and undergraduates nowadays live in a world characterized by dramatic, cultural, economic, social and educational differences. Notwithstanding the immense diversity in living environments, an unprecedented and unifying global media culture has developed that challenges and often surpasses such traditional forms of socialization as family and school. This has made digital communication tools like blogs, sms, cell phones, video sharing indispensible in the lives. It is considered a blessing due to the conveniences and benefits that have greatly affected the daily lives of the young people. While most may benefit, we must bear in mind the downsides of such improvements. Personal communication is compromised, and with convenience all kinds of information is easily shared, increasing chances of young adults falling prey to the wrong kind of information. However, in todays context-the information age, the benefits that digital communication can bring to young adults, far exceeds the harms that can befall. Digital communication, is thus in my opinion a blessing to young people. Digital communication plays a huge role in the pervasive and powerful media. Inappropriate information transmitted results in young people becoming innocent victims, as they might not have reach a stage of development that allows them to appropriately process the information they are receiving...

...In recent years, there has been an extraordinary rise in digital communication, especially through mobile phones and social media; reading the newspaper has become reading a blog, watching the television has become watching YouTube videos. Younger generations have been pretty much born in a world that resolves around sharing and reading content on the web. Digital communication considerably influences the way we speak. But is this good or bad? Multi-modal language is simply any type of commination that isn’t in person, face-to-face. One of the most common forms of multi modal is through social media. Because of it’s popularity, social media is clearly having an impact on language, however there are advantages and disadvantages to the way they influence it. Advantages include that it is usually free, you are able to keep in contact with distant family and friends and make potential friends who have common interests as you. Disadvantages however are that there is legal and ethical issues such as cyberbullying and fraud, people may become addicted and distract themselves from reality and that people rely on social media and lose real life social skills. Majority of the people that use social media are teenagers. There are plenty different language features used in digital communication. They each have different purposes and effects. Emoji’s/Emoticons -- Emoji’s are used to show the overall emotion of the message. Through texting you are not able to see a person’s facial expression...

...Telephone and Digital Communications • Define inbound telemarketing. Give an example. o Inbound telemarketing is when someone calls into a place for information or the purpose of being sold a product. This may happen from them seeing some kind of advertisement for a product or receiving something on the internet, or via the mail that inclines them to call in. Inbound telemarketing is usually the easiest because the person is calling you and they normally know some information about what they are calling about and they have some kind of interest in the product or service that they will be offered. o An example would be Dun and Bradstreet. They are the credit reporting agency for businesses. When I worked for them people would call us because they had heard of Dun and Bradstreet and they wanted they credit report and it was my job to sell them services which could enhance their experience and their business’ credit report. • Define outbound telemarketing. Give an example. o Outbound telemarketing is cold calling. Most times people do not know that they are going to receive a phone call from an outbound telemarketer unless there was some kind of lead that was generated and they were advised at the time that someone may be calling them about the products that they offer. o I also did cold calling for Dun and Bradstreet. The company had purchased lists of business names, phone numbers, addresses and owners. We would call these business ask to speak to the person that we had...

...Lizbeth Mota & Austin Soto ENGL 21003 Section K Digital Communications Pattern 11/3/15 Patterns of Communication in Scientific Societies The way that societies as a whole interact has changed tremendously since the beginning of the modern communication era. With the development of electronic computers and, subsequently, the invention of the internet, the science community particularly has had a drastic shift in the scientific publication process. Journals that took months to publish, print and be delivered, are now instantly made available through online websites. Moreover, modernizing resources results in the increase in the available, accessible information for the community. Since the beginning of the century, online science journals have made the scientific community cohesive by providing with the most up to date findings for research being conducted in particular fields as well as all are new ways to “interact” amongst individuals. For this report we have chosen four online resources that provide information on the area of biomolecular biology and neurology, we will enumerate their usefulness to our particular field of interest and their incidence in our future professional careers. In the 1850’s, an Austrian monk Gregor Mendel discovered that he can manipulate plant offspring to breed plants selectively with traits that he wished to see; he cross-bred two tall pea plants and found that the offspring almost certainly expressed the "tall" feature. At the time...

...INTRODUCTION The Encoder Device division (EDD) at Digital Communications is a producer of communications devices for Government Agencies in the United States. The company works closely with Government Agencies and due to the nature of the devices they produce, and their application the Company works on a 'need to know' basis and as such production departments are compartmentalised. Production of Voice Ratio Encoding (VRE) devices is on going, however a new microprocessor has been developed, rendering the existing microprocessor obsolete. As a consequence the microprocessor needs be fitted to all existing devices in the 'field' and all new devices in production. EDD wish to win this 'replacement contract'. EDD have vast experience in 'ground up' bids for entire programmes but not on single sub-assemblies for resale. EDD are confident that they understand their business well, however they fear they lack the detailed information about the costs associated with sub assemblies. They wish to make an attractive but profitable bid for the contract. STRUCTURE OF EDD. EDD has four separate production departments: Data Encoding (DE), Video Encoding (VE), Voice Ratio Encoding (VRE) and Variable Wire Encoding. This specific contract is exclusive to VRE. EDD therefore need to ensure that they have the correct division of costs between each production department and that the cost for each department is then split correctly between the underlying manufacturing processes within...

...Media communication is the process in which data is transferred from one computer to another. This involves transmission of digital of information to different devices through wireless or cabled connections. The data transmitted over networks could be either digital or analog. * Analog signals are continuous signals that vary in strength. Sound is an example of an analog signal. Telephones have transmitters that encode sound waves into electromagnetic waves, which then travel over wires toward their destination. The receiving telephone decodes the electromagnetic waves back into sound waves. Our brains then decode the sound waves into the words we hear. Computer modems use the same principle. Analog signals can be represented digitally. For instance, a high electromagnetic voltage could be interpreted as 1 and low voltage as 0. * Digital signals are discrete rather than continuous. Either there is a signal or there isn't a signal. Telegraphs transmit data with discrete signals. You either hear a tap or you do not hear a tap. Discrete signals can be represented by on and off pulses. The duration of a discrete signal can be varied, as with dots and dashes in Morse Code. To explain how this data is transmitted over the network, first I had to explain the mediums. Mediums are ways, which the data use to travel from one place to another. These mediums may vary depending the environment or type of network. The most commonly used data communication media include: *...

...Introduction to Digital Data Transmission 1.1 INTRODUCTION This book is concerned with the transmission of information by electrical means using digital communication techniques. Information may be transmitted from one point to another using either digital or analog communication systems. In a digital communication system, the information is processed so that it can be represented by a sequence of discrete messages as shown in Figure 1–1. The digital source in Figure 1–1 may be the result of sampling and quantizing an analog source such as speech, or it may represent a naturally digital source such as an electronic mail file. In either case, each message is one of a finite set containing q messages. If q = 2, the source is referred to as a binary source, and the two possible digit values are called bits, a contraction for binary digits. Note also that source outputs, whether discrete or analog, are inherently random. If they were not, there would be no need for a communication system. For example, expanding on the case where the digital information results from an analog source, consider a sensor whose output voltage at any given time instant may assume a continuum of values. This waveform may be processed by sampling at appropriately spaced time instants, quantizing these samples, and converting each quantized sample to a binary number (i.e., an analog-to-digital converter). Each sample value is therefore represented by a sequence of 1s and 0s, and the communication system associates...

...Assignment Questions: 1) Explain why we use multiplexing and give an example of a communication method that uses multiplexing. . We use multiplexing to divide a high speed circuit to let multiple devices use the circuit at the same time. Multiplexing is a way to offset the costs of installing a lot of telecommunication lines in an office or organization. A well designed multiplexer cam make the most out of a small amount of lines. 2) Give data communication examples for each of these data flow methods: Simplex Simplex data only flows in one direction like a river that flows to the ocean, data is transmitted and received one way only. Half Duplex Half Duplex can transmit two directions, one at a time. Like a truck drivers two way radio, only able to receive while not transmitting. Full Duplex .A full duplex circuit is divided equally. A telephone is a full duplex as it can send your voice signal and receive a voice signal at the same time. 3) Describe how FDM is different from TDM .FDM divides the circuit in a way that the signals can be sent at the same time, each on its own frequency so they do not interfere with one another. TDM makes the connected computers take turns in order to transmit data which wastes some capacity because time is allocated even while there is no data being transmitted. 4) Provide one advantage for each of the following media types: Twisted pair Twisted pair is favored over coax because of its lower cost Coax Coax is favored...

...| Analog and Digital Comparison | NTC/362 Fundamentals in Networking | EDWARD BROWN | Jose Giralt | 3/18/2013 | | A signal is simply the transmission of data from one place to another place. In our day to day life we deal with various signals constantly like signals from music, power lines, telephones, and cellular devices. Analog and digital are two kinds of signals which are used for the transmission of information from source to destination. Usually the information to be transmitted from one place to another is either audio or video. This information signal is then transformed into those signals which can be transmitted via different channels. For the analog format, the data is transformed into electrical pulses with varying amplitude while for the digital format; the data is transformed into binary format representing two amplitudes. We have various such equipment like analog or digital phones, fax machines, modems, clocks, watches etc. Analog technology is the older one and has been used for decades. It is cheap too but the problem with analog signals is that there is a limitation on the size of the data that can be transmitted at any given point of time. With the advent of digital technology many improvements and new techniques have been introduced. Now days almost every appliance or equipment is based on digital technology. In this, the transmitter translate the data into binary form and the receiver re assemble and produces the...

...or samples. The result is called digital representation. Strictly speaking, digitizing means simply capturing an analog signal in digital form. For a document the term means to trace the document image or capture the "corners" where the lines end or change direction. The term digitization is often used when diverse forms of information, such as text, sound, image or voice, are converted into a single binary code. Computers predate to the Digital Age. Prior to the 1950s, computers were analog, using vacuum tubes. Later, vacuum tubes were used in conjunction with diodes. Like the digital computers that came later, analog computers used binary logic, but instead of being directly controlled by a program consisting of 1s and 0s, the state of the vacuum tube was changed by a change in voltage. The voltage change was analogous to a 1 (power on) versus a 0 (power off). In 1956, MIT built the TX0, the first general-purpose, programmable computer to use transistors. Digitization occurs in two parts: Discretization and Quantization. Discretization is the reading of an analog signal A, and, at regular time intervals (or frequency), sampling the value of the signal at the point. Each such reading is called a sample and may be considered to have infinite precision at this stage. Quantization is when the samples are rounded to a fixed set of numbers (such as integers). Data Communications There are many different ways in which analog converts to digital. For example, signals are continuous...

...I have learned a lot in intro to Mass Communication. This class has helped me a lot in what I want to do for my career. I’m glad that they have a class called Intro To Mass cause it kind of helps u find out if u are in the right major or not. It introduces u Intro Mass Communication and gives you information on what this major is going to be about. I learned a lot in chapters 1,5, and 6. In chapter one I learned a lot about digital natives, digital immigrants, and mass media. Digital natives are people who grew up in a world where digital technologies and the Internet were already in place. Then you have your digital immigrants who are transitioning into the digital age. I thought that was pretty cool how they had two different groups, and mass media is the exchange of information and meanings between individuals and groups. In chapter 5 I learned about sound recording, speakeasies, and commercial radio. Sound recording is the recreation of sound waves including voice, music, and sound effects. A man by the name of Thomas Alva Edison is the one who created sound recording. Then I learned about speakeasies, which are illegal saloons and dance halls that quickly sprang up all over the country. After that came the commercial radio which is advertising backed radio that helped to increase the radio's financial base. Chapter 5 helped me a lot cause this chapter focused on my career so I learned a lot. In chapter 6 I learned about hybrid films, sound-on-filming technology, and...

...Integration paper 3 technological divide among poor and rich Beth BUrnett Integration paper 3 technological divide among poor and rich Beth BUrnett 2016 2016 As Digital Natives, who were born into the technological world, we should be striving to find a way to at least make the basic modern day technologies available to those who need it most. Imagine waking up every day and not being able to reach over and check your phone for missed messages, or even being able to turn on your light to see what you are doing. We don’t think about how fortunate we are to have those “luxuries”. For 3 billion people, this is reality, no phones, no internet, no communication. When you wake up the first thing you do is check your phone, believe it or not 4.4 Billion people still do not have access to Modern day technology. As a Digital Native, I believe this needs to change, not because they are missing out, but because it can be a matter of life or death. Despite the rapid spread of technology, only 1.16 Billion people have a working phone line. That means 6.14 Billion people do not have a way to call for help. For example if the people of Haiti did not have cell phones when they were hit by the massive earthquake, they would not have gotten the help they needed as quickly as they did. Many people have heard about the Ebola virus that swept across Africa and the sub- Saharan dessert areas, because many of the villages that were severely affected by the disease did not have active phone...

Even now, a lot of digital information beyond imagination is being accumulated all over the world. Not only the amount of information is increasing, but the production rate of one is also getting speedy. This explosion of information has some reasons. The main reason is technology development. It can actualize things which were impossible in the past. The digital technology changes a lot of information into digitization. Also, many people utilize them with the powerful mean digital device. Men communicating by information contributed to increase the amount of information. Humans who escaped from illiteracy and economic hardship have generated many kinds of information, which are utilized in several fields such as politics, economy, law, culture, science, and so on. The production rate of information is faster than the speed of technology development. Though the digital devices handling the information are getting various, storage space is not enough to store the increased information. Sea is not calm, but it has that big waves. Likewise, lots of information comes to our life. It is important to judge what information is...

...How does a Multipoint circuit differ from a point to point circuit? Multipoint is also called a shared circuit. In this configuration, many computers are connected on the same circuit. This means that each must share the circuit with the others, much like a party line in telephone communication. The disadvantage is that only one computer can use the circuit at a time. When computer is sending or receiving data, all others must wait. The advantage of multipoint circuits is that they reduce the amount of cable required and typically use the available communication circuit more efficiently. Multipoint configurations are cheaper than point-to-point configurations. Point-to-point configuration is so named because it goes from one point to another (e.g., one computer to another). These are also called as dedicated circuits because they are dedicated to the use of these two computers. This type of configuration is used when the computers generate enough data to fill the capacity of the communication circuit. This can get very expensive, particularly if there is some distance between the computers. 3. Describe Three types of guided media. Guided media are those in which the message flows through a physical media such as a twisted pair wire, coaxial cable, or fiber-optic cable. a. Twisted pair wire is most commonly used. It is a pair of wires used in standard telephone wiring. They are twisted to reduce interference caused by the other twisted pairs in the same cable bundle...

...Abstract We are living in a world in which communications play a vital role. The way we communicate was transformed by the information age which opened the doors to a whole new world of possibilities. A few decades ago our telecommunications flourished with the invention of the television, the radio and the phonograph, which functioned based on an analog format. These inventions allowed for broadcast of radio and television news and shows across the United States. Record music and movies in VHS format were also introduced to American homes. With the introduction of the digital format our telecommunications received a tremendous boost, and some of the early media outlets were replaced by more efficient ways of communication. This paper will describe some of the factors behind the recent loss of audience and sales in such media outlets as record music, movies, network TV, DVDs and video games. The introduction of the digital format changed the way we watch TV; high definition made possible to see a picture like never before, like if we were looking through a window. Digitalization allowed for a much better sound and picture quality in CDs and DVDs, which replaced the vinyl disc and the VHS tape. These media, however, continued to evolution so much so that in recent years media outlets such as newspapers, movies, network TV, DVDs and video games became obsolete. Digital is the key factor. Media outlets such as newspapers, movies, DVDs and video games are...
