Download file to see previous pages Initially computer networks were used for military purposes, but today every a huge population of individuals as well as businesses use computer networks to communicate with each other. Computer networks have become quite wide spread and the sole reason due to which these network enjoy such popularity is that these networks allow individuals to communicate those pieces of information that once mankind could not even imagine to communicate. Even though, computer networks have become so popular, these networks have several disadvantages associated with it and this is the reason why these networks are even highly criticized.
Computer networks are not a very old concept and they are not even a very new one. Computer networks that individuals experience in the era of 2015 came into existence during the period of 1940 when an individual named George Stibitz transferred information and data from a machine called Teletype machine to a calculator and then utilized the same method to send information from the calculator to the machine (Casey, 2011, p.608). This activity is the base of the computer networks that the society in the 21st century enjoys. During the period of 1950s the first and the foremost computer network was experienced in the shape of a radar system that was utilized by the armed forces and this radar system was recognized as SAGE (Semi-Automatic Ground Environment) (Casey, 2011, p.608). By the period of 1960 the first ever computers were connected with each other (Casey, 2011, p.608). These computers were mainframes and these computers were used for the purpose of allowing users to reserve airline tickets in a semi-automatic manner. Approximately two years later researchers such as JCR Licklider became interested in connecting output based hardware with such as teletypewriters with a computer and for this purpose he developed a group called ...Download file to see next pagesRead More

Healthcare Computer Network Architecture

... of the of the 10 February Healthcare Computer Network Architecture Answer Internet Protocol (IP) is a numeric address that configured on each computing device that wishes to communicate with other devices on a computer network. Likewise, this address demonstrates the address of a specific device on the network. For example, a computer that is configured on the network will possess an IP address: However, for establishing connectivity, subnet mask, gateway and other relevant protocols contribute for successful data transmission. Likewise, a version 4 IP address comprises of five classes i.e. Class A, Class B, Class, C , Class D and Class E. Subnet demonstrates the class of an IP address. Moreover, the gateway defines... is a...

...VPNs require an in-depth understanding of public network security issues and proper deployment of precautions. The availability and performance of an organization's wide-area VPN (over the Internet in particular) depends on factors largely outside of their control. VPN technologies from different vendors may not work well together due to immature standards. VPN needs to accommodate protocols other than IP and existing ("legacy") internal network technology. FIREWALL A firewall is a system for protecting the confidentiality, integrity, and availability of data held on networked computers and, increasingly in this age of electronic business, corporate...

...infrastructure of WLA Company hinders the development of the company. This is due to the fact that the infrastructure is insufficient, the data stored is not secure i.e. can easily be compromised by unauthorized person and above all, the data backup plan is not efficient as the mode of backup is prone to disasters such as earth quakes and floods in the location of the company. Moreover, there is no documentation for the current IT infrastructure. There is no documentation explaining the network setup in the company. Also, the software and the hardware are outdated. Considering that the computers are still running windows XP, it implies that the OS may not support the current versions of application...

Computer Network

... A wireless protocol transmits over a channel 20 MHz wide over a noiseless channel. How many bits/sec can be sent if 64 level digital signals are used? Channel bandwidth = 20 MHz = 20 * 106 Using the Nyquist theorem; C = 2Blog2M C = 2 * 20 *106 * log 264 =240Mbps 2) If a binary signal is sent over a 20 3KHz MHz channel whose signal-to-noise ratio is 40 20 dB, what is the maximum achievable data rate? We know that 10log10S/N = 40dB It follows that S/N = 100 Now from the Shannon theorem; The maximum number of bits per second = H* log2 (1 + S/N) = 20KHz * log2(1+100) Log2(101)= 6,658 = 20 * 6658 =133160 Now from the Nyquist theorem; The maximum number of bits per second = 2 * H * log2V = 2 * 20 * log22 =40 The Nyquist theorem gives...
