Computer Science, Information Technology and Networking al Affiliation) According to Forouzan et al., conventionally, there are four major media formats of transmission. They include, the twisted pair cable, the coaxial cables, wireless and fiber optics. However, they all possess varying characteristics and transmission capacities. The media types differ in terms of performance, bandwidth, distance between repeaters, susceptibility to noise, their costs and their security needs (Forouzan et al., 2007).
Their differences are highlighted in the table below.
Media Type
Bandwidth
Performance
Distance between Repeaters
Twisted Pair Cable
1MHz
Poor
Very short
Coaxial Cable
1 GHz
Fair
Short
Wireless
100 GHz
Good
Moderate
Fiber Optics
75THz
Excellent
Very far
Some characteristics such as security are difficult to compare and contrast because they differ in terms of their transmission mode. For example, security needs may entail authentication, encryption security levels and modes of detecting intrusion. Additionally, the costs involved in the three mediums are difficult to contrast due to the different costs involved such as- acquisition costs, installation costs and maintenance costs.
With regards to the data transmission speeds of coaxial cable, microwave, fiber optic cable, satellite and twisted pair cable, in descending order, they are as below :-
a. Fiber Optic Cable
b. Satellite
c. Microwave
d. Coaxial Cable
e. Twisted Pair Cable
For an entrepreneur who wants to establish a global satellite radio system, I would begin with using at least two GEO satellites strategically placed above the globe. This would enable the satellites to transmit signals to the radio satellite receivers. Additionally, the entrepreneur would have no interference since the satellites are placed directly above the earth and would orbit continuously. The frequency of the transmission would range from 5GHz to around 30GHz.
A synchronous connection can be likened to a lift that stops every floor to allow people on and off from the ground floor to the tenth floor. The first four floors refer to the input messages, while the next six floors are responsible for producing data.
The network chosen is a local LAN, which is wirelessly connected and also through coaxial cables. If additional media is required, a USB cable can be used for connecting to the network. In some instances, one may want to use an external hard drive. In such instances, the hard drive is connected either via the USB or wirelessly.

...Network’s Tolerance Fault Introduction In the world of today, networking or linking of different computing devices in order for them to share data has become the convenient way to people who want to share their files or send their e-mails from different parts of the country. Most networks are built hand in hand with both the computer hardware and computer software (Cook, 2003, p103). This paper tries to analyze the network’s fault tolerance, the cabling and how to configure the basic router commands and the basic router configuration in a networking environment.

...any need to wait for responses. The use of HTTP pipelining allows the reduction of lag time since the client can send multiple requests at the same time and can then wait for their corresponding responses (W3, 2004 b). The use of this technique allows drastic improvements in the internet connection speed since HTML pages and other content tends to load faster. The typical TCP packet is constructed such that it houses multiple HTTP requests due to HTTP pipelining. Consequently, HTTP pipelining aids in sending a lower number of TCP packets on the network to perform the same tasks which allows a reduction in the overall network load and congestion.

Topology is a framework defining the arrangements of every object on the network. This includes workstations, network components, servers, WAN devices and many more. There are total five topologies to design a computer network. However, all of these five topologies share certain factors. Each topology demonstrates disadvantages as well as advantages that will be discussed further. The five different topologies are illustrated below: 1.1 Star Topology Star topology is recommended for the wired local...

...are presently using DNSSSEC. Despite there being several DNSSEC-related tools for network administration, only a few options are available for regular users on a computer. Opportunities The deployment of the DNSSEC technology offers a great opportunity for those operating their own DNS servers. This is because there are plenty of documentation regarding how configure DNSSEC for any DNS server being used. Additionally, sites like the DNSSEC-Tools project (16) are also in existence that provides tools that help in the process and software like OpenDNSSEC (17) capable of automating a significant portion of the process (Daley, 2011). The other significant opportunity in the deployment of DNSSEC is that the market demand for...
