Transmission Media Advantaged Disadvantages Essay

Excerpt from Essay :

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 routers and networks.

Wired media has some advantages and disadvantages as compared to wireless transmission media. Some of the advantages of wired transmission media include the fact that it is more secure than wireless to an extent that hackers have minimal opportunities to access the computer system. In addition, this medium is faster and more reliable, is easy to set up and troubleshoot, and does not require additional wireless equipment. However, the disadvantages of this media include its requirement of greater start-up costs due to multiple wires, potential installation costs, and reliability. Wired media is also disadvantageous because it is not so flexible when positioning computers or mobile devices, not very convenient with users of mobile devices or laptops, and supports fewer links than a wireless.

On the contrary, wireless transmission media is common in the modern society because the world is increasingly going wireless. Wireless media is increasingly used because it provides an effective way for getting rid extra or additional cords or cables used in wired media. Wireless media is media used to broadcast information or data through radio wave signals, microwave, satellites, infrared, or radio towers. In a computer system, a wireless network involves connecting a computer or other compatible device to a Super Hub without the use of any cables or physical pathways. Since it does require any cables for connections, wireless media enables the connection of many different devices to the Internet at the same time.

The advantages of wireless media include its ability to enable connection or linking of many devices at the same time and it is relatively cost-effective because using cables throughout a building is not only costly but also relatively hard to maintain (Evan, 2013). In addition, wireless media is ideal for mobile devices and laptops, provides very secure networks when combined with highest strength security settings, and promotes faster browsing. In contrast, the disadvantages of wireless media include the likelihood of its performance being affected by thick walls or electrical interference, probability of unauthorized users to gain access, can be relatively slower than wired media, and may require additional devices such as adapters.
