National LiquidatorsAuction snipingAuction sniping is the process of watching a timed online auction (such as on eBay), and placing a winning bid at the last possible moment (often seconds before the end of the auction), giving the other bidders no time to outbid the sniper. Some bidders do this manually, and others use software designed for the purpose. A bid sniper is a person or software agent who performs auction sniping. There are also online sniping services, where the software agent is run from a website rather than the sniper's own computer. This decreases the failure rate of the snipe, because the website is expected to have more reliable servers that might be quicker to react. Experienced bidders of online auctions with fixed ending times often prefer entering bids late in the auction to avoid bidding wars (multiple rounds of bidders each increasing their maximum bid to temporarily regain "current highest bid" status) or bid chasing (where the presence of an existing bid encourages others to bid on the same item). Economic analysis of sniping (Roth and Ockenfels, 2000[2]) suggests that it is a rational gain-maximizing (i.e., price-minimizing) strategy for bidders in auctions which fulfill two criteria: 1) the end time is rigidly fixed (such as those on eBay), and 2) it is possible to gain additional information about the "true" value of the item by inspecting previous bids. For example, a novice antiques buyer may prefer to bid in auctions which already have bids placed by more experienced antiques buyers, on the grounds that the items which the experienced buyers are interested in are more likely to be valuable. In this case, more informed buyers may delay bidding until the last minutes of the auction to avoid creating competition for their bids, leading to a lower winning bid. Analysis of actual winning bids on eBay (Yang and Kahng, 2006[3]) suggests that winning bidders are more likely to have placed a single bid late in the auction, rather than placing multiple incremental bids as the auction progresses. When bidders decide to use non-manual sniping, they lay their trust to either sniping software, or to an online sniping service, and provide them with their eBay username and password. To many bidders, this is a deterrent to using automated sniping services at all. Furthermore, unlike eBay, which transmits passwords from the bidder's browser in a secure manner, some online sniping services do not use a secure connection to transmit the eBay username and password from the bidder's browser to their servers. This effectively degrades the protection provided by eBay. It is, therefore, advisable to make sure that a sniping service supports SSL before using it. As a preventive measure, non-frequent shoppers could change their eBay password before using sniping software and then change it once again after the bidding ended. This would limit the risk for the account by the time when temporary password is used.auctionAn auction is a process of buying and selling goods or services by offering them up for bid, taking bids, and then selling the item to the winning bidder. In economic theory, an auction may refer to any mechanism or set of trading rules for exchange. There are several variations on the basic auction form, including time limits, minimum or maximum limits on bid prices, and special rules for determining the winning bidder(s) and sale price(s). Participants in an auction may or may not know the identities or actions of other participants. Depending on the auction, bidders may participate in person or remotely through a variety of means, including telephone and the internet. The seller usually pays a commission to the auctioneer or auction company based on a percentage of the final sale price.Automatic test equipmentAutomatic test equipment is any automated device that is used to quickly test printed circuit boards, integrated circuits, or any other related electronic components or modules. For some Automatic test equipment is ATE. Automatic test equipment devices are essentially always controlled by computers. In the past, custom-designed controllers or even relay controls were used to control ATE An Automatic test equipment system can be simple as or complex ATE as a system containing dozens of complex test instruments capable of automatically testing and diagnosing faults in complex electronic systems, such as very sophisticated flying-probe testers. Automatic test equipment systems are used to test a wide range of electronic devices and systems, from simple components (resistors, capacitors, and inductors) to integrated circuits (ICs), printed circuit boards (PCBs), and complex, completely-assembled electronic systems. Automatic test equipment is widely used in the electronic manufacturing industry to test electronics components and systems after they are fabricated. ATE is also used to test avionics systems on commercial and military aircraft. ATE systems are also used to test the electronic modules in today’s automobiles. Automatic test equipment systems typically interface with an automated placement tool, called a Handler, that physically places the Device Under Test so that it can be measured by the equipment. Over the past four decades, ATE has grown from specialized systems for electronics test applications to a wide range of applications in all facets of the electronics industry. Many ATE platforms used in the semiconductor industry output data using Standard Test Data Format. |

computerA computer is a machine that manipulates data according to a list of instructions. Computers take numerous physical forms. The first devices that resemble modern computers date to the mid-20th century, although the computer concept and various machines similar to computers existed earlier. The first programmer was Ada . Early electronic computers were the size of a large room, consuming as much power as several hundred modern personal computers. Modern computers are based on comparatively tiny integrated circuits and are millions to billions of times more capable while occupying a fraction of the space. Today, simple computers may be made small enough to fit into a wristwatch and be powered from a watch battery. Personal computers in various forms are icons of the Information Age and are what most people think of as "a computer"; however, the most common form of computer in use today is the embedded computer. Embedded computers are small, simple devices that are used to control other devices — for example, they may be found in machines ranging from fighter aircraft to industrial robots, digital cameras, and children's toys. The ability to store and execute lists of instructions called programs makes computers extremely versatile and distinguishes them from calculators. The Church–Turing thesis is a mathematical statement of this versatility: any computer with a certain minimum capability is, in principle, capable of performing the same tasks that any other computer can perform. Therefore, computers with capability and complexity ranging from that of a personal digital assistant to a supercomputer are all able to perform the same computational tasks given enough time and storage capacity.
