LAN Networks - Essay Example According to Cache et al., some of the features, in terms of contrast purposes, are problematic due to the lack of a standardized criteria for comparison, such as the security needs of the transmission media format. They include factors such the different type of costs (purchase, maintenance and installation) and the security needs of the medium. This is because there are different types of security threats and each medium of transmission is susceptible to different risks. Some security threats pertain to the mode of intrusion detection or authentication and verification (Cache, J., & Liu, V. 2007). According to White, in terms of data transmission speed from the highest to the lowest with regards to fiber optic cable, twisted pair, satellite, coaxial cable and microwave, they are as listed below:- As an expert, I would advise the entrepreneur wishing to institute a global satellite radio framework in his business to purchase not less than two satellites (GEO). The GEO satellites would then be suspended in a strategic location to ensure adequate connection and data transmission. In addition, the strategic location will ensure that signals transmitted from the satellites are received by the radio satellite. If placed strategically, frequency the transmission frequency will be around 20 GHz and the satellite will orbit almost exponentially if there are no mechanical problems. The most appropriate analogy for a synchronous connection and how it functions is a lift and how it halts in each floor to allow people to enter or exit from the ground floor to the top most floor. Just like a lift, a synchronous connection has a large information amount (passengers entering the lift) in addition to the required data (passengers already in the lift). If the lift has fourteen floors, then the first six floors represent the input messages while the last eight floors are set aside for data
