Cisco CCNA – CCENT Certification Exam Training – Broadcasts, Hubs, Routers, And Switches

In a past Cisco CCENT confirmation test instructional exercise, we discussed communicates and the capability of a transmission storm. (On the off chance that you missed that one, visit my site’s Tutorials segment.) In the present instructional exercise, we’ll talk about a few distinctive normal organization gadgets and how they help to restrict broadcast engendering – or now and again, how they don’t help!

In the “don’t support” office, we’ll discover center points and repeaters. These two gadgets work at Layer 1 of the OSI model (the Physical layer), and their sole intention is to reinforce the electrical signs sent over the link. They don’t have anything to do with exchanging or directing, and they don’t assist with restricting transmissions. (A center point is fundamentally a repeater with more ports.)

On the opposite finish of the range, we have switches. Switches work at Layer 3 of the OSI model (the Network layer), and naturally switches don’t advance transmissions. They can be designed to “make an interpretation of” certain transmission types into unicasts, however you’ll become familiar with that in your CCNA examines.

Since switches don’t advance transmissions, there’s a misguided judgment that switches have nothing to do with communicates. Switches can for sure create 인터넷방송, and they can acknowledge them – yet they won’t advance them. That is a significant differentiation.

Between these two limits, we discover switches. Switches work at Layer 2 of the OSI model (the Data Link layer), and the default conduct of a switch is to acknowledge a transmission and forward it out each other single port on that switch aside from the port that previously got the transmission.

In the event that that seems like a ton of transmission sending, it is! In the event that we have a 80-port switch and one port gets a transmission, of course a duplicate of that broadcast will be sent out the other 79 ports. Undoubtedly, not those hosts associated with those switchports need to see that broadcast, and sending superfluous transmission brings about a pointless utilization of organization assets, especially transfer speed.

Fortunately for us, there is an approach to arrange a Cisco change to restrict which ports get that communicated, and we’ll investigate that technique in the following portion of my Cisco CCENT affirmation test instructional exercise arrangement!

Water Conservation in Central Texas

Water Conservation in Central Texas  

Water Conservation

As we move forward into the 21st century two things are going to remain true: the population of the City of Austin and surrounding area is going to increase, the amount of water available will not. The Colorado River’s flow will not expand to cover the increased demand and the aquifers beneath us will not be sustainable unless  Conservative News   rainfall patterns change and the extended drought ends. The damming of the Colorado to form the Highland Lakes was in response to the extended drought of 1950-57, however there are no plans in the works for any additional reservoirs.

“Currently, about 95 percent of Texas is in either a severe or exceptional drought status and the past year {2011} has been the worst one-year drought in the state’s history,” says John Nielsen-Gammon, State Climatologist at A&M University. He also puts forward the possibility the drought could extend into the future as far as 2020.

Austin’s water supply challenges are becoming more evident as demonstrated by recent record heat and drought conditions. The emergence of the “Sometimes Islands” in Lake Travis are a reminder of the pressure our water supply system can suddenly come under when our average annual rainfall amounts drop considerably. (Austin gets about 34 inches of annual rainfall.) The good news is that Austin has secured long term water rights and contractual rights for roughly twice as much water as is currently being used – to water in the river that runs through the city. Austin’s adoption of its aggressive conservation goals comes from dedication to water conservation as a value and with long term sustainability in mind, and without the immediate financial or water supply pressures faced by places like California and western desert cities who have to pipe water from distant sources reliant upon historic rainfall amounts that have diminished over recent years.

It should also be noted that strong conservation efforts by Austin do not necessarily result in more water remaining in the Colorado River and the Highland Lakes. Under the current LCRA Water Management Plan, any water savings realized by the City of Austin is water available to be sold by LCRA to other customers. The biggest water user along the Colorado River is not the City of Austin, but downstream rice farmers who regularly use more than three times as much water annually as does the City of Austin (including water used by Austin Energy to generate power). In fact, during the drought, while Austin implemented Stage 2 restrictions, including limiting irrigation to one day per week, rice farmers made no cutbacks and actually exceeded their projected use in the Water Management Plan. The City of Austin used a total of around 139,000 acre feet of water, compared to the 450,000 used by rice farmers downstream.

Water Conservation: A Local History

The City of Austin’s first water use management ordinance was enacted in 1983. It allowed for the implementation of water restrictions in response to infrastructure constraints, but more as a crisis management tool than an actual water conservation strategy.

Since that time demand has increased as the population soared.

1990 – 466,000
2000 – 656,000
2010 – 790,000

Source Ryan Robinson, City Demographer, Dept of Planning, City Of Austin, March 2011

Between 1995 and 2009 water use per year has gone from 39,585 to 53,328 (in millions of gallons) Because of this changing demographic Austin has focused more on water conservation as a means to extend the available infrastructure capacity as well as reducing the city’s carbon footprint. To enhance ongoing conservation efforts, Austin’s City Council passed a resolution on August 24, 2006 that set a goal of reducing peak day water use by one percent per year for ten years. As part of that resolution, the City Council established a Water Conservation Task Force (WCTF) and charged it with drafting a policy document consisting of strategies and implementation plans for new water conservation initiatives that would allow Austin to meet its goal for reducing peak day use.

As part of the resulting actions in the 2007 charge, City Council established the Citizens Water Conservation Implementation Task Force (CWCITF), whose members included environmental advocates, development advocates, irrigators, and others with expertise and interest in water conservation, and tasked them with monitoring water conservation efforts in Austin. On August 6, 2009, the City Council adopted a resolution that directed the CWCITF to work with City staff and applicable Boards & Commissions to produce a report recommending additional water conservation measures to reduce water use beyond the 2007 WCTF recommendations. After this report was complete, on May 13, 2010 City Council charged the City Manager with evaluating the CWCITF’s recommendations and developing an action plan that would reduce average water use in Austin to 140 gallons per capita, per day (GPCD) or lower by 2020.

In July 2010, Austin Water introduced a pilot program to encourage residential customers to replace turfgrass with native plants or non irrigated areas. Even at a modest incentive amount, this program is not expected to generate enough water savings to meet cost benefit benchmarks; however, it will generate interest in xeriscaping and opportunities for customer education that have non quantifiable benefits, including reductions in chemical use and runoff.

Austin Water will continue to provide free irrigation system checkups to customers, and will increase focus on high use customers through targeted marketing and outreach. Austin Water is developing online tools to help customers with lower water use perform basic system checkups and maintenance so that staff time can be focused on the highest water users. Customers required to submit regular irrigation evaluations would not be eligible for this free service once the mandatory requirement is implemented; efforts would focus on small commercial and high residential users. This measure does not meet cost benefit benchmarks for average day savings due to the seasonality of irrigation; however, it was determined to be a successful peak day management strategy in the 2007 WCTF report.
