Transmission Media:
Transmission media, which is also known as communication media, refers to a means with which information is broadcasted from one location to another. The transmission medium in a data transmission system is regarded as the physical pathway between the sender and the receiver of a message or information. Generally, transmission media in computer communications are divided into two categories i.e. bounded and unbounded media. Bounded media are the physical pathways for broadcast information like fiber optic cable while unbounded media is transmission through air like cell phone signals. The bounded media is also known as wired media because it involves physical links while unbounded media is also known as wireless media. Notably, the quality and characteristics of a transmission media is determined by the attributes of the signal and medium.
Wired and Wireless Media:
Wired and wireless media are important means of transmitting or transporting information since they provide different means and benefits in some areas. Due to the differences between the two media, it is important for organizations to use both of them to capitalize on the benefits or advantages of each. Generally, wired media is media used to transport information through a network that involves the use of physical pathways i.e. wire. The most common types of wired transmission media include telephone cables and coaxial cables. With regards to computer networks, a wired home network involves connecting the computer or other related devices to a Super Hub with an Ethernet cable (“Wired or Wireless”, n.d.). However, the use of wired networks in computer systems has lessened significantly because of the introduction and prevalence of wired r...

Conclusion:
Wired and wireless transmission media are pathways that are used to transport data or information through the use of various means. While wired media utilizes cables or wires to transport data, wireless media transmit data through radio signals or waves and do not require any cables. As a result, these systems have certain advantages and disadvantages that make them effective and ineffective for various purposes. The other important aspect of transmission of data is structured wiring systems that are fast becoming the norm for all networks. These systems are widely used because of their benefits i.e. consistency, simplified troubleshooting, support for future applications, and support for multi-vendor equipment. Consequently, organizations will benefit from sites that provide information regarding structured wiring protocol.
Wireless networks – While the term wireless network may technically be used to refer to any type of network that is wireless, the term is most commonly used to refer to a telecommunications network whose interconnection between nodes is implemented without the use of wires, such as a computer network. Wireless telecommunication networks are generally implemented with some type of remote information transmission system that uses electromagnetic waves, such as radio waves, for the carrier and this implementation usually takes place at the physical level or “layer” network.
Meanwhile, the advent of early PC’s and the recognition of the value in networking devices together gave rise to Local Area Networks. These LAN’s were developed from a business customer perspective, which placed more emphasis on costs and ease of use over reliability. There were a number of different competing LAN technologies, two of the most common being Token Ring (IBM) and Ethernet (everyone else). The triumph of Ethernet in the marketplace, to the extent where it is included in every PC, game console and some refrigerators, provides a consistent and relatively inexpensive way to build internal networks with relative ease.
Network cables are another component that is used in communication between network devices. Cables are used to connect one network device to other via several different connections. The most reliable type of connection between two or more devices is to use a wired connection. These connections can be used to share data and access between servers, PCs, printer...
Media or medium of communication has been conceptualized to effect and drive information to the greater masses because it’s the venue where information can be linear form of communication. This essay will discuss what it is meant by media according to online Business Dictionary defines as the communication channels through which news, entertainment, education, data, or promotional messages are disseminated.” This may include broadcasting and narrowcasting medium such as newspapers, magazines, TV, radio, billboards, direct mail, telephone, fax, and internet, the Business Dictionary further includes in this definition.
McLuhan’s work with literature and culture produced the revolutionary thought that “the medium is the message.” In other words, cultures are changed not only by the “content” of technology, but also by the technology itself.
“The medium is the message,” uttered by the late media scholar and theorist Marshall McLuhan, and they have been revered and dissected ever since they were spoken. There has been several different interpretations on the premise of McLuhan’s words, and the meaning behind them. The best way to start unraveling his theory, is to get a general understanding of the terms used in his famous quote. In McLuhan’s own words, a medium is simply “an extension of ourselves.” Simply put the medium personifies or enhances what we as humans cannot do on our own. In a mass media perspective this means the use of technology including radio, television, and the Internet to project our thoughts, feelings, and senses (Frederman) . Finally, it is important to note that the plural of the word medium is media. Now that there is a general understanding of the medium, the other important word McLuhan spoke of is the “message”. The message is simply what the audience perceives through the medium. This could be anything from watching a television program or listening to the radio. Also, note that some believe the message McLuhan preached is a lot more complicated and not obvious. This view can be explained by, the message isn’t the news, but the attitudes that are affected by watching or listening to the message. Whichever, definition is taken for the “message”, the dissection of McLuhan’s quote will still be interpreted in a similar fashion.
What is electronic media? Electronic Media is information or data that is created, distributed and accessed using a form of electronics, electromechanical energy or any equipment used in electronic communications. The common equipment we use on a day to day basis to access Electronic Media is our television, radio, computer, cell phones and other devices transporting information to and from us by means of electronic involvement.
The term 'medium' can be analysed and it can show how content is received by the wider audience. A medium in this context refers to 'an intervening agency, means, or instrument by which something is conveyed or accomplished', this definition is from dictionary.com. The internet easily fits this description, as it is essentially originated a large network with widespread nodes to keep the government in touch. This is shown in the history and the origins of the internet.
Local Area Networks also called LANs have been a major player in industrialization of computers. In the past 20 or so years the worlds industry has be invaded with new computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to share information between computers with a simple relatively inexpensive system of network cards and software. It also lets the user or users share hardware such as Printers and scanners. The speed of access between the computers is lighting fast because the data has a short distance to cover. In most cases a LAN only occupies one or a group of buildings located next to each other. For larger area need there are several other types of networks such as the Internet.

This report will describe the two forms of data communications in terms of the physical interfaces and modes of operation. It will describe the features of data communications equipment in relation to synchronous and asynchronous communication including modems, network terminating units and sending and receiving equipment.
Communication is the sharing of information between two or more persons or groups to reach a common understanding. In the communication, the information or ideas conveyed must be understood. Effective communication allows participants to properly exchange ideas. Communication is the two way process of exchanging information. Communication can be done through oral, verbal and written communication. Information is transmitted as words, tone of voice, and gestures and postures. Information can be shared face to face or by telephone, fax, e-mail, text messaging, videoconferencing, electronic-portfolios, chat, memos, letters, reports, etc. The number and types of methods increase as information technology systems become ever more involving a great deal of worldly experience and knowledge.
What is Media? Did you ever wonder how we can find out information we need, or just want to know what is going on around the world? We use it in all different types of ways to retain the knowledge and communication that we use on a day to day basis. Media is one of the many ways of communication that is used to receive and deliver information to influence people across the world. The use of media is communication being advertised through televisions, radios, internet, magazines and newspapers. These are by far the main resources of how we use media to reach our audiences. Media can be classified as a forum of information that is ready to be released into the world. How we do it is entirely up to the person who withholds that information.
