EC APPLICATION: CRAIGSLIST: THE ULTIMATE ONLINE CLASSIFIED COMMUNITY If you want to find (or offer) a job, housing, goods and services, social activities, romance, advice, and much more in over 700 local sites in 13 lan-guages, and in more than 70 countries worldwide (2014 data), go to Craigslist (craigslist.org). The site has much more information than you will find in newspapers. According to their website, Craigslist receives 80 million new classified ads every month. Each month there are more than 60 million visitors to the site in the United States alone (see craigslist.org/about/factsheet). Finally, there are over 50 billion-page views per month. For more statistics, see alexa.com/ siteinfo/craigslist.org and siteanalytics.com-pete.com/craigslist.com/#.Uw27nfmICm4. According to Alexa.com, Craigslist is the eleventh most visited site in the United States. In addition, Craigslist features over 100 topical discussion forums with more than 200 million user postings. Every day, people from 700 local sites in 70 countries worldwide check classified ads and interact on forums. Craigslist is considered by many as one of the few web-sites that could change the world because it is simply a free social-oriented, popular, and useful notice site. Although many other sites offer free classifieds, no other site comes close to Craigslist. For more information, see craigslist.org/ about/factsheet. Users cite the following reasons for the popularity of Craigslist: As an example of the site’s benefits, we provide the personal experience of one of the authors, who needed to rent his condo in Long Beach, California. The usual process to get the condo rented would take 2–4 weeks and $400 to $700 in newspaper ads, plus ads in local online sites for rental services. With Craigslist, it took less than a week at no cost. As more people dis-cover Craigslist, the traditional newspaper-based classified ad industry will probably be the loser; ad rates may become lower, and fewer ads will be printed. In some cities, Craigslist charges for "help wanted" ads and apartments listed by brokers. In addition, Craigslist may charge for ads with rich media features.
Concerns About Craigslist
Critics charge that some users post illegitimate or false ads on the site and the Craigslist staff are unable to effectively monitor this practice. Some users have complained about questionable ads and scams being posted. Craigslist also attracts criminals seeking to commit fraud by paying with bad checks. The anonymity of Craigslist’s users as well as the lack of ratings encourages unlawful acts. Another concern is that adult services make up a significant portion of the total traffic on the site and may involve illegal activities, especially concerning minors. With the sheer volume of users and ads posted per day, such monitoring is not possible given the modest workforce of only 40 plus that the site employs (data of 2014). (As of September 8, 2010, Craigslist has been trying to control such activities.) On the other side, many supporters contend that attempts to control Craigslist may simply cause users to use other, less-regulated sites. In China, a company called 58.com Inc. (58. com) is modeled after Craigslist and provides similar information and generates sizeable revenue and profits. The company is listed in the NYSE under the symbol WUBA. Sources: Based on Clark (2008), Liedtke (2009), and craigslist.org (accessed May 2014).

Use the spanning-tree vlan vlan-id root secondary global configuration mode command to create a different root bridge if needed.
With this command, the switch's priority is set to the predetermined value of 28,672. As a result, in the event that the primary root bridge fails, the backup switch will take over as the root bridge. The root bridge is determined by the switch with the lowest priority, or BID (the lower the priority value, the higher the priority). For instance, setting the priority to a lower value than the other switches on the network will guarantee that a certain switch is always the root bridge.

Balayage. The French word "balayage" means "to sweep" or "to paint." It's a highlighting method that gives the hair a lovely appearance. Just the surface of your hair is painted with bleach or hair colour in balayage. A colorist uses the Balayage technique, which is a highlighting method, to paint bleach or haircolor only on the top layer of your hair, without covering the entire part in dye.

connection speed is technically a measure of capacity: T/F
The statement "connection speed is technically a measure of capacity" is;
False.
Connection speed and capacity are not the same thing.
Connection speed, also known as bandwidth, is a measure of how quickly data can be transferred over a network connection. It is typically measured in bits per second (bps) or bytes per second (Bps). It is a measure of the rate of data transfer, and it is typically used to measure the speed of internet connections.
Capacity, on the other hand, is a measure of how much data can be stored or transmitted over a network connection. It is typically measured in bytes (B) or bits (b). It is a measure of the amount of data that can be transferred over a network connection, and it is typically used to measure the storage capacity of a hard drive or the number of users that can be supported on a network.
Therefore, connection speed is not a measure of capacity. The two are different from each other. Connection speed it is a measure of the rate at which data can be transferred over a network connection.

The correct answer is O four data inputs and two select inputs, A four-line multiplexer.
A combinational logic circuit known as a multiplexer (MUX) is used to switch one of several inputs to a single common output line. An many-to-one data selector is a multiplexer. In accordance with the bits on the choose line, a multiplexer chooses one of the several data accessible at its input. A 4-to-1 multiplexer accepts 4 inputs and routes one input—the one you choose—to the output. Selection inputs regulate the choice of input.

Barton conducts an experiment using three metallic bars that might be magnets. The bars are labeled a, b, and c. The ends of each bar are numbered 1 or 2.
Based on the data, the prediction that Barton should expect to happen is A1 attracts C2.
Magnets have two poles, namely the north pole and the south pole. When magnetic poles of the same kind are brought close to each other, the two poles will repel each other. Conversely, different poles will attract each other. The magnetic field will form a magnetic force.
Label 1 is likened to the north pole and label 2 is likened to the south pole so that the two attract each other. So if A1 is written with C2 then they will attract each other. If B2 is brought close to C2, they will repel each other.
So, the proper conclusion from Barton's experiment is that A1 attracts C2.
