Ex Input:
Context_1 : Forrest Corry Parry (July 4, 1921 – December 31, 2005) was the IBM engineer who invented the Magnetic stripe card used for Credit cards and identification badges. Context_2 : In computing (specifically data transmission and data storage), a block, sometimes called a physical record, is a sequence of bytes or bits, usually containing some whole number of records, having a maximum length, a "block size". Data thus structured are said to be "blocked". The process of putting data into blocks is called "blocking", while "deblocking" is the process of extracting data from blocks. Blocked data is normally stored in a data buffer and read or written a whole block at a time. Blocking reduces the overhead and speeds up the handling of the data-stream. For some devices such as magnetic tape and CKD disk devices blocking reduces the amount of external storage required for the data. Blocking is almost universally employed when storing data to 9-track magnetic tape, to NAND flash memory, and to rotating media such as floppy disks, hard disks, and optical discs. Context_3 : Interchange Plus is the common name for a pricing structure for accepting credit card transactions by merchants. The Interchange fee is an important factor in determining the actual cost of accepting credit cards. Interchange pricing is what the Visa and MasterCard associations along with credit card issuing banks charge merchant account providers to process credit and debit card transactions. Merchant Account providers then charge a markup on interchange known as interchange plus pricing to process the transaction and provide customer service to the merchant accepting the credit or debit card payment. Interchange Plus pricing is known as the most honest and transparent form of pricing for merchants looking to accept credit cards. There are a lot of credit card processing companies that only offer interchange plus pricing. Context_4 : Tape hiss is the high frequency noise present on analogue magnetic tape recordings caused by the size of the magnetic particles used to make the tape. Effectively it is the noise floor of the recording medium. It can be reduced by the use of finer magnetic particles or by increasing the amount of tape used per second to record a signal. It can also be reduced by increasing the track width of the recording. A 3 dB reduction in hiss occurs for every doubling of the track width. Context_5 : Credit card fraud is a wide-ranging term for theft and fraud committed using or involving a payment card, such as a credit card or debit card, as a fraudulent source of funds in a transaction. The purpose may be to obtain goods without paying, or to obtain unauthorized funds from an account. Credit card fraud is also an adjunct to identity theft. According to the United States Federal Trade Commission, while the rate of identity theft had been holding steady during the mid 2000s, it increased by 21 percent in 2008. However, credit card fraud, that crime which most people associate with ID theft, decreased as a percentage of all ID theft complaints for the sixth year in a row. Context_6 : Postal address verification (also known as address standardization, address validation, address verification and CASS certification) is the process used to check the validity and deliverability of a physical mailing address. According to the United States Postal Service, an address is valid (or mailable) if it is CASS-certified, meaning that it exists within the comprehensive list of mailable addresses in their Address Management System. This is different from the credit card Address Verification System (AVS), which is the method used by credit card processors to authenticate ownership of a credit card by verifying that the account on the credit card matches the billing address on file. Credit card AVS does not determine deliverability of an address. Context_7 : VisionPLUS is a financial software application from First Data Corporation. Originally developed by the Paysys Research and Development Group, this application is mainly used for credit card transaction processing by banks and transaction processing companies, storing and processing credit card, debit card, prepaid, closed end loan accounts and similar financial transactions such as Visa, MasterCard, American Express, Europay, and private label transactions against those accounts. More than 600 million cards around the world are processed on different versions of this application software. Context_8 : The Active Archive Alliance is a trade association that promotes a method of tiered storage which gives the user access to data across a virtual file system that migrates data between multiple storage systems and media types including solid-state drive/flash, hard disk drives, magnetic tape, optical disk, and cloud. The result of an active archive implementation is that data can be stored on the most appropriate media type for the given retention and restoration requirements of that data. This allows less time sensitive or infrequently accessed data to be stored on less expensive media, and eliminates the need for an administrator to manually migrate data between storage systems. Additionally since storage systems such as tape libraries have very low power consumption, the operational expense of storing data in an active archive is greatly reduced. Context_9 : A magnetic stripe card is a type of card capable of storing data by modifying the magnetism of tiny iron-based magnetic particles on a band of magnetic material on the card. The magnetic stripe, sometimes called swipe card or magstripe, is read by swiping past a magnetic reading head. Magnetic stripe cards are commonly used in credit cards, identity cards, and transportation tickets. They may also contain an RFID tag, a transponder device and/or a microchip mostly used for business premises access control or electronic payment. Context_10 : A tape head is a type of transducer used in tape recorders to convert electrical signals to magnetic fluctuations and vice versa. They can also be used to read credit/debit/gift cards because the strip of magnetic tape on the back of a credit card stores data the same way that other magnetic tapes do. Cassettes, reel-to-reel tapes, 8-tracks, VHS tapes, and even floppy disks and modern hard drive disks all use the same principle of physics to store and read back information. The medium is magnetized in a pattern. It then moves at a constant speed over an electromagnet. Since the moving tape is carrying a changing magnetic field with it, it induces a varying voltage across the head. That voltage can then be amplified and connected to speakers in the case of audio, or measured and sorted into '1's and zeroes in the case of digital data. fact_1 : Forrest Corry Parry (July 4, 1921 – December 31, 2005) was the IBM engineer who invented the Magnetic stripe card used for Credit cards and identification badges. fact_2 : A magnetic stripe card is a type of card capable of storing data by modifying the magnetism of tiny iron-based magnetic particles on a band of magnetic material on the card.

Context_1 : Exeter ( ) is a cathedral city in Devon England with a population of 129,800 (mid-2016 est. ). It lies within the county of Devon, of which it is the county town as well as the home of Devon County Council. The administrative area has the status of a non-metropolitan district under the administration of the County Council; a plan to grant the city unitary authority status was scrapped under the 2010 coalition government. The city is on the River Exe about 37 mi northeast of Plymouth and 70 mi southwest of Bristol. Context_2 : John Bampfylde (8 April 1691 – 17 September 1750) of Hestercombe in Somerset, was an English politician from Devon, who served as Member of Parliament for Exeter, Devon (1715–1722) and for the County of Devon (1736–1741). Context_3 : Exeter is a constituency composed of the cathedral city and county town of Devon represented in the House of Commons of the UK Parliament. The constituency has had a history of representatives from 1900 of Conservative, Liberal Party, Independent and Labour representation and has been represented since 1997 by Ben Bradshaw of the Labour Party, who served in government as a Health Minister and as Secretary of State for Culture, Media and Sport (2009–2010). Context_4 : John Hooker (or "Hoker") "alias" John Vowell (c. 1527–1601) of Exeter in Devon, was an English historian, writer, solicitor, antiquary, and civic administrator. From 1555 to his death he was Chamberlain of Exeter. He was twice MP for Exeter in 1570/1 and 1586, and for Athenry in Ireland in 1569 and wrote an influential treatise on parliamentary procedure. He wrote an eye-witness account of the siege of Exeter during the Prayer Book Rebellion in 1549. He spent several years in Ireland as legal adviser to Sir Peter Carew, and following Carew's death in 1575 wrote his biography. He was one of the editors of the second edition of Raphael Holinshed's "Chronicles", published in 1587. His last, unpublished and probably uncompleted work was the first topographical description of the county of Devon. He founded a guild of Merchant Adventurers under a charter from Queen Mary. He was the uncle of Richard Hooker, the influential Anglican theologian. Context_5 : Exeter Cathedral, properly known as the Cathedral Church of Saint Peter at Exeter, is an Anglican cathedral, and the seat of the Bishop of Exeter, in the city of Exeter, Devon, in South West England. The present building was complete by about 1400, and has several notable features, including an early set of misericords, an astronomical clock and the longest uninterrupted vaulted ceiling in England. Context_6 : The Devon County War Memorial is a First World War memorial, designed by Sir Edwin Lutyens and situated on the cathedral green in Exeter, the county town of Devon, in the south west of England. It is one of fifteen War Crosses designed by Lutyens to a similar specification, and one of two to serve as a civic memorial in a city. The first proposal for the county's war memorial was to complete the construction of a cloister at Exeter Cathedral to be dedicated to the Devon's war dead, but this scheme was abandoned due to lack of funds. After considering multiple proposals, the Devon County War Memorial Committee commissioned Lutyens to design a War Cross instead. The committee chose to site the memorial on the green of Exeter Cathedral after scouting several locations. A war memorial for Exeter itself was being considered concurrently, but the committees for the two projects failed to work together, resulting in two separate memorials—the county memorial by the cathedral and Exeter City War Memorial in Northernhay Gardens. Context_7 : The Devon and Exeter Institution is a subscription library in the City of Exeter, Devon, founded in 1813 for "The general diffusion of science, literature and the arts". It is situated at 7, Cathedral Close, Exeter, in a building facing the north side of Exeter Cathedral which was formerly the Exeter townhouse of the Courtenay family of Powderham Castle. Context_8 : John Pollow (fl. 1413–1419) of Exeter, Devon, was an English politician. Context_9 : The Church of St Mary Major, formerly Exeter Minster, was a historic church and parish in the City of Exeter, Devon, dating from the 7th century. It pre-dated the first Exeter Cathedral by some five centuries, was rebuilt several times, but was finally demolished in 1971. It was situated to the immediate south-west of Exeter Cathedral, the site today being a grass lawn. Context_10 : This list is of towns and cities in Devon in order of their population, according to the 2011 census data from the Office for National Statistics.
