Bandwidth

The U.S is the known as one of the most technologically advanced countries in the world, yet the U.S has one of the slowest and most expensive internet speeds. Japan, whose internet bandwidth averages 81 Megabytes per second (MBPS) is very cheap at $0.40 per MBPS compared to the pricey and slow internet speeds of the U.S at 15 MBPS for $5.66 per MBPS. That is almost six times slower and 14 times more expensive than Japan. There are many possible solutions ranging from expensive options such as Google Fiber, Sony ‘Nuro’, Fiber-to-the-home (FTTH), and inexpensive options like local service providers contributing to the increase in internet bandwidth. Many people grew up with either dial up connection or satellite connection. Having said this,…

predictable network service by providing dedicated bandwidth, controlled jitter and latency, and improved packet loss characteristics. The basic idea is to pre-allocate resources (processor and buffer space) for sensitive data. Each of the following schemes require customized configuration of output interface queues [8]. • First In First Out (FIFO): the simplest form, which also known as first-come, first-served (FCFS) queuing, involves buffering and forwarding of packets in the order of…

What is LAN? LAN stands for Local Area Network. LAN is a network that connects a group of computers within a building like a home, office or a school. For LANS to connect together and share information within computers, Ethernet is most commonly used. LAN does not need cables to connect to the different devices (e.g printers) however radio waves can be used to communicate. Difference between client-server and peer to peer network: Client Server Peer to Peer Resources can be removed at…

these claims seem awesome, they also have down sides. Most internet service providers offer payment tiers to their subscribers. Payment tiers are multiple levels of service a costumer can purchase, so for example someone who just wants to web browse are able to pay for a lower bandwidth (speed of the service), while someone who want to play online videogames will have the option to pay more for a higher bandwidth. Internet service provider’s argument is with total net neutrality, this payment…

signals to occupy a transmission channel and optimizing the use of available bandwidth. Therefore, the receiver separates the signals from the users by cross correlation of the received signal with each of the user unique code sequences. If the code sequence is designed to have a small cross correlation, it can minimize the crosstalk inherent. There is a spreading signal in code-division multiple access (CDMA) systems…

an important role with connecting users to the digital world. While it remains as the most popular technology for networking, it is crucial to understand the limit of certain wireless protocols and how it works in different situations. The most recent Wi-Fi protocol that this report will focus on is, 802.11ac, also known to be the next generation for wireless networks to be equipped with new technologies that could provide faster speeds, capacity, and range. The predecessor, 802.11n, wireless…

Throughout our research, we have found how cognitive ability tests, interviews, and other hiring practices may lead to discrimination. We now know that some cognitive ability tests are prone to age-based adverse impacts. In order to avoid discrimination, management must be aware of how age differences influence cognitive ability test scores. Furthermore, the amount of bandwidth media involved in interviews can effect discrimination. High bandwidth media outlets such as face-to-face interviews…

identifying what are FDMA, TDMA and CDMA and how to maintain the communication seamlessly and the roaming service as well as the cost of roaming service. Furthermore, the 1G, 2G, 3G and 4G generations will be discussed. Finally, the potential issues or risks while using the mobile wireless will be discussed. 1. the technical details of FDMA, TDMA and CDMA (1) FDMA Frequency Division Multiple Access (FDMA) bandwidth is divided into narrow frequency slots and is use to allocate a unique…

Richard Zheng Dr. Bruce Farcau POS 2041 18 November 2014 Net Neutrality: The Open Internet Since the very early days of the Internet, it had mostly been used for sending e-mails and basic communication online. However, as the years passed and the world wide web expanded further, more people began using the Internet for other services such as viewing informative and entertaining videos, enjoying their favorite music, playing unique games, and receiving countless sources of information. Because…

ITM 301 Lab & Assignment 2 Deqa Yusuf Student #:500566949 Part A: Both CAT5 and CAT5e are UTP cables but the difference between these 2 cables is the quality. CAT5 has a 100 MHz signaling while CAT5e can have a signaling rate of up to 350 MHz. Not only that but the wiring is different as well, the CAT5 has simple wiring while the CAT5e has copper wiring. In short the CAT5e is a much more advanced cable compared to the CAT5. The CAT6 cable is a cable that has 4 wires which are covered in foil,…
