I participate in team of FTTX meeting.Engineer and technicians speak about faulty modems and card failures .The team leader has made the work sharing..In addition;I learned some concepts such as Xdsl,ADSL,DSLAM.Some information about DSL; Digital Subscriber Line, or DSL, is a technology for bringing high-bandwidth connectivity to homes and small businesses over ordinary copper telephone lines. xDSL refers to the family of digital subscriber linetechnologies, such as ADSL, HDSL, and RADSL. Connection speeds for DSL typically range from 1.544 Mbps to 512 Kbps downstream and around 128 Kbps upstream. In addition, a DSL line allows for one line to carry both voice and data signals, and for the data part of the line to be continuously connected. DSL achieves higher data transfer rates by utilizing more of the available bandwidth spectrum. Ordinary telephone service only makes use of the 0 – 3400 Hz frequency range, which accounts for the 56 Kbps speed limit on standard analog modems. DSL eludes the 3400 Hz frequency boundary by outmoding the digital-to-analog conversion that modems perform and …show more content…

And unlike cable modems, DSL is not a bus technology, so the bandwidth available to the end user is more consistent.However, despite all of its positive attributes, DSL is not without flaw. For instance, in order to be eligible for DSL, the end user must be geographically within a certain distance from the central telephone office,otherwise the signal degradation is too great and DSL is unfeasible (for ADSL that distance is two miles.) In addition, numerous standards still exist for DSL,hardware is still comparatively pricey, and service is available only in limited areas. Despite these drawbacks, DSL is still a faster alternative to analog modems and ISDN, and should rival cable modems as far as actual bandwidth

The SIFS( Shortest Inter-Frame Space),derives the time between the last transmission and high priority transmissions such as positive acknowledgments(ACKs),Clear-To-Send(CTS)frames,polling responses, continuation frames in a burst transmission. priority is given to the positive ACK frames so that a station which has just completed the reception of a frame can give immediate feedback to the sender. RTS and CTS frame coordinate correspondence between sets of stations so that different stations know not the medium to be free for the time of the exchange .This is one of the reasons for why the control frames have priority over normal data transmissions. If a station finished transmitting a frame and has enough time left to send an additional frame, it is allowed to send after a SIFS.

1. Identify drives to which the databases and/or logs will be backed up, ensuring that there is enough disk space to accommodate the backups for the retention period that you choose. 2. Identify drive that will be used for data or log files. These will usually be on SAN storage and hence on a different drive from the operating system and SQL Server installations.

6-1. Examples of organizations that could have information silos could be a local restaurant and a chain restaurant. Both probably have information silos if they have a database for each area of work. This could happen if each area doesn 't have a way to communicate their data to the others, which causes problems in the business system running smoothly. For the local store, an EAI would probably be the best because it is for smaller businesses and would disrupt business for a shorter period of time.

The competitor’s flashlight was easy to take apart, inside of it we can find the wires, the battery, the light bulb, and others components of it. First we took apart the front case and we were able to see all the parts that it has inside, we started taking them apart so we were able to see how they’re placed and how they make it work, trying to not mess them up or to put them in different places than they were before. We used mostly our hands to do all that, we just used some tools to take apart the front case. Our new design is so different than the original one, we made it bigger, its made of hard plastic material and aluminum, also its water proof because campers are exposed to all changes of temperature.

SCENERIO Baxter, a year three Aboriginal student who at age three developed a sensorineural hearing impairment after repeated exposure to Otitis Media. Baxter uses a cochlear implant on one ear, as the other was not viable. Unfortunately, due to bullying in previous years Baxter has limited confidence in his communication skills and will rarely speak aloud, except with the teacher privately, close friends, and family. Baxter often communicates using basic sign language, but relies heavily on gestures. He is currently working with a speech therapist to increase his speech and language skills and to increase his confidence.

In interviewing my mother and sister-in-law, I was fully aware that there would be two distinct perspectives relating to health, healing, birth and death. The fact that my mother did not acknowledge our indigenous bloodline was of no surprise to me. That is partially due to the society she grew up in, where repressing any indigenous identity, were rejected influences by colonization and intergenerational trauma. Whereas, interviewing my sister-in-law who is indigenous and identifies as a Kichwa woman, grew up with a completely different philosophy, belief and acceptance. The reason I state this is to give a clear understanding of how these two opposite ideologies influenced my world.

People have the right to the same internet networks, same speed, and the same access no matter who they choose as a provider for that specific service. Major cable and telephone companies want to offer faster connecting speed for the people who are willing to pay more but neutrality says you cannot do that. Mobile phone companies such as T-Mobile and AT&T offer faster data plans for purchase. The whole of net neutrality is to have an Open and free internet. Basically it is where ISP can’t play favorites when you want the access to the content to be neutral.

ISPs would be able to legally apply quality of service mechanics which would bottleneck services unless they chose to pay the ISP for a “fast lane” to the consumer. Instead of a single pipe with a single speed, the pipe would have divisions that the provider could use to ignore sections of a user’s pipe to prioritize preferred data. This idea stems from the Comcast / Netflix decision in February 2014 to create a direct link between the two (at an undisclosed price) after Comcast had been allegedly throttling Netflix traffic due to the assessed volume of Netflix traffic traversing Comcast’s infrastructure. Due to the lack of restrictions on ISPs, the expectation, and fear, is that providers will use this tactic to create artificial “speed bumps” in data delivery to create more revenue and degrade the overall experience of the internet. Equally troublesome is the ISP’s capability to limit the speed of your data delivery (the “private good” you are leasing from them) based on the amount of roads they must transit outside of their network (Nye & Welch, 2013, p. 194).

The information that we receive is a series of digital signals that come through these wires. These are then split into phone and internet by a microfilter, plastic box that plugs into the main BT socket. The speed depends on the distance from the local telephone exchange. The age and quality of the copper wires can also influence your speed. Cable broadband uses fibre-optic to transmit data, cables are partially made of fibre-optic material, which allows for far less signal degradation and much faster broadband speeds.

This could happen because when it comes to competition the people of the better networks that provide better service are able to charge more causing more people to drop and change to a cheaper provider. In this case it would be some provider that can barley run anything with their internet. On top of that some internet providers “promise” to provide the best service they can to their customers but what they meant by promise is a two hour phone call with someone at a phone that will leave the little song playing to keep you distracted and make you waste more time.
