Wired network has been around for a very long time and throughout that time it has proven its self around the world. Wireless network has emerged as more lenient, accessible, user friendly which it benefits the users to a certain extent. Examining and analyzing each of these types of network capabilities each have their advantages and disadvantages and it is based according to its network characteristics, due to this fact wired and wireless networks have very different hardware requirement, range, mobility, reliability and benefits. The focus in the following paragraphs is to compare the Wired, Wireless and fiber optic networks on different points that include but not limit information for their reliability, mobility, speed, security.
The comparison for wired, wireless and fiber based network is very simple yet at the same time a bit complex. When the term wired is referred in IT is used for the sole purpose to differentiate between the wireless connections and the ones that involve cables. When setting up a wired connection there are cables that are linked to it and transfer the data in and out devices and computer systems. As we all know cables interconnected is what transfer valuable source of data in between personal computers. It has been known that just with a single wired network can be used to connect each computer to a single network. If we go the high end large networks on the other hand need the back up and startup of multiple routers and switches that connect to each and every single PC. A router or a switch generally links up to a cable modem, t1, or internet connection that provided the adequate access to the devices connected to the network. To that affect there are many advantages to using a wired network, this being a handful it starts with cost. Cost depends on how well put out and thorough a configuration has been put together, on that note the firewalls installed for the wired network are fairly low-priced to install. Typically, the hardware lifespan withstands the tested time before upgrading in looked at or even needed. Security will be the second-best advantage of a wired network. If a network is configured with the correct firewall and security applications one can be at peace and know that the network is being monitored 24/7 for illicit activity. Speed is the third advantage for a wired network. Since there is a direct contact between the two points wired networks are generally way faster that wireless connected networks. Lastly visibility, reliability and stability wired networks are not visible by other wired networks that are relatable. Thus, having no interface with any connection, yet having the network still communicate effectively with other connection points on the network. Reliability and stability is well recognized when configuration is properly wired as a completed network. This is referred to as a workhorse system that is extremely reliable once everything is put into place.
When referencing wireless networks, it is best described as infrared or radio frequency signals that allow and share resources and info amongst devices that are linked to each other. In today’s society, there many devices that are wireless like cell phones, laptops, PDA’s satellite receivers etc. As we see today cell networks have done a dramatic improvement of data transmission speed, which allows a variety of higher speed mobile data services.
services. On the other hand, Bluetooth, Hiperlan and infrared transmissions are short ranged transmissions that while in the process of creating a wide range of new applications this short ranged transmission keeps improving for the expansion of new application, home networking etc. Being that wireless networks have helped out tremendously the type of society we live in, there are flaws and disadvantages for it as well. Wireless network can cost triple or quadruple the amount than what a setup of a wired network would cost. File transfer speeds tend to be much slower than wired connections and there are many reasons why this happens but the most commonly known would be the location that you find yourself currently vs the location where the networks hub may be. As mentioned before the speed in which the wireless connection operates is much slower than a wired connection and also speed will throttle according to the location of the network hub. Keep in mind that the wireless connection can be obstructed by various sources such as furniture, walls etc. Knowing this it is typically less secure.
To compare the advantages of a wireless network rather than a wired network, we will see the brief differences that one lacks and the other benefits. We have already established that a wireless network gives the ability to roam around freely with a device whether is a handheld device or laptop. With the wireless connection users, can file share and other different task between each other without having to be connected to cables or ports, this includes uploading and downloading files from different sources. There are times that the wireless networks is able to carry a larger amount of users due to its mobility and because the connection ports are not limited with the users.
Fiber cable based network
This network is unique in its own way, its signal is if in form of light and its carried throughout with glass fiber. A fiber optic network system involves of three main components: optical transmitter, fiber optic cable and an optical receiver. Advantages for the fiber optic cable are many, for starters they have replaced the cooper wire communication throughout the world, due to its electrical transmission advantages. It also has a greater distance advantage for coverage with the strong bandwidth that all other cables can’t compete with. Security is a big concerned and since the awareness of data being transmitted through the fiber, it is very difficult to pinpoint what exactly goes through when its being done via light. Though fiber optic transmission is full of advantages, it’s also full of disadvantages. Some of these disadvantages are that it is difficult to install, also due to their high demand the cost of these fiber optic cables are immensely doubled the price of what a regular copper cable would be. For the conclusion fiber optic transmission, has been used for data transmission and it has shown that throughout the years of usage it has grown in popularity do to its efficiency and high transmission capacity, and the fantastic bandwidth and great speed. Do to this great improvement research has shown that it can promise foreseen opportunities to expand its and be continuously researched and expanded to cater for future demands.
This can become a weapon of a double edge because there are ways that the signal can be tapped into once someone has gained access to the bare fiber or into the interconnect points. Research shows that the light that carries the data passes longitudinally down the glass fiber. Yet there is some of that light that can be seen through the sidewall of the fiber if a professional is conducting a field test. Fiber optic transmission has found a enormous display of applications in computer systems. Some design attentions depend on the specific application.
For a complete program of network security that functions without any problems the physical layer of the network needs to be taken into consideration, by examining, analyzing and testing it from top to bottom. Designs and preplanning are essential pre-composing a proper physical security network. Wired and wireless network connections are very common now a day and are seen all throughout workplaces and private residences. As large companies, even homes are under wired networks the scale keeps tilting over the wireless connection network because wired networks lack mobility at any given time. Because of this factor research shows that within the next upcoming years the speed of networks will have a tremendous increase as it has gone up in the past few years.
