In facsimile , the center-to-center distance between two recorded spots measured perpendicular to the recorded line.
In facsimile, the center-to-center distance between two scanning spots measured perpendicular to the scanning line on the subject copy. The numerical value of this term will depend upon the type of system used.
A two channel video channel. One is for color (chrominance) and the other for black and white (luminance). This designation is used for video signals that keep separate the luminance and chrominance information, thus preventing some of the normal NTSC artifacts, E.G., cross- color and cross-luminance.
Year 2000. The millennium bug. What happened when your computer hit the year 2000. There were supposed to be three happenings. First, it would move its date to 1900 and stay there. In this case programs that used date calculations ” like figuring how much money you have in your insurance policy ” would screw up. For example, many old mainframe programs used the two-digit 95, instead of the four-digit 1995 in the date field. That meant that when it hit 00 or 01, the computer wouldn't be able to figure that the difference between 01 and 95 is 6. (Figure it. 2001 minus 1995 = 6). Second, it would move its date to 1900 and you'd have to manually change it back. Third, it would move its date to 2000 flawlessly. Most PCs manufactured after 1995 handled the Y2K problem flawlessly. Many mainframe and minicomputers manufactured before that wouldn't. Some phone systems would also mess up and stop working altogether. Some were expected to work in strange ways, like producing the wrong information on calls being made or being received. Billions of dollars were invested throughout the world in business and in governments rewriting computer software. As a result most of the fears of great disaster didn't materialize. Y2K was a great non-event in the history of computing.
An antenna system which employs a basic antenna element with parasitic reflector and director elements in order to achieve highly directional characteristics.
A popular search engine and directory on the Web. Yahoo stands for "Yet Another Hierarchical Officious Oracle." Yahoo! began as the bookmark lists of two Stanford University graduate students, David Filo and Jerry Yang. After putting their combined bookmark lists organized by categories on a college site, the list began to grow into an Internet phenomenon . It became the first such directory with a large following. Filo and Yang postponed their graduate work and became part of a public offering for a multimillion dollar corporation. Yahoo's stock went up, then down. Now it's up a little.
Americans love yard sales, also called garage sales. Families sell their old junk to other families who see it as treasure . The process is repeated endlessly. There are variations on this theme, as you can see from this joke Bob Dunagan sent me: A man was walking one day when he came to a big house in a nice neighborhood. Suddenly he realized there was a couple making love on the lawn. Then he noticed another couple behind a tree. Then another couple behind some bushes. He knocked on the door of the house. A well-dressed woman answered . The man asked her what kind of a place this was? "This is a brothel," replied the woman. "Well, what's all that making love on the lawn? queried the man. Replied the woman , "Oh, we're having a yard sale today."
Yazam is the Hebrew word for entrepreneur. www.yazam.com is an online meeting place for entrepreneurs and investors.
An alarm that indicates a piece of equipment has suffered a critical (i.e., red alarm) fault. In T-1 circuits, a yellow alarm sent back toward the source of a failed transmit circuit in a DS-1 two-way transmission path . In superframe mode, the yellow alarm is generated by forcing bit two of every channel in the superframe to zero. In extended superframe mode the yellow alarm is sent via the facility data link. See also T-1. See also Yellow Signal.
In telecommunications, a signal sent back in the direction of a failure, indicating that the input of a network element has failed. The yellow signal varies with the DS framing used. See Remote Alarm Indication and VT Path Remote Failure Indication and Yellow Alarm.
A coaxial cable used in 10Base-5 networks. It is also referred to as "Thick" coax. This was the first cable used on many early LANs.
A directory of telephone numbers classified by type of business. It was printed on yellow paper throughout most of the twentieth century until it was obsoleted in the late 1990s by dial up yellow page directories operated by voice processing systems and in the early 21st century by electronic directories delivered on disposable laser disks. As a concession to history, the laser disks are now painted bright yellow. Actually, yellow pages remain one of the phone companies' most lucrative sources of revenues . Advertising rates are not cheap. There is now competition. There are many "Yellow Pages" directories, since AT&T never trademarked the term "Yellow Pages." Some "yellow page" directories are better value than others. And some are more legitimate than others. Some actually never get printed or, if they are printed, are not printed in great quantity and are not distributed as widely as their sales literature implies. Many businesses have been suckered into paying money for listings and advertisements in directories that never appeared. This fictitious directory scam also has happened with "telex" and "fax" directories. This "scam" is fraud by mail and is heavily stomped upon by the US Postal Service. As a result, many fake directories ( especially the telex ones) are "published" abroad.
"I don't want yes men around me. I want everybody to tell me the truth even if it costs them their jobs." Samuel Goldwyn, film producer.
Yiddish is a Germanic language written in Hebrew characters , and was the native language of millions of Jews before the Holocaust. Yiddish is still very much a living language, spoken by hundreds of thousands of Jews as their first language in New York, Jerusalem, Montreal, Antwerp, and other Jewish communities.
A person who buys very long-term bonds (20 years plus) in order to get the highest possible yield. The problem with buying such long-term bonds is that the prices of these bonds fluctuate wildly. When interest rates rise, their prices fall. When interest rates fall, their prices rise. Buying long, long-term bonds only makes sense when interest rates are falling, as they did in 2002, for example.
Your Mileage May Vary. A response usually given when the answer is not precise and depends on the user 's own circumstances. YMMV is an acronym used in electronic mail on the Internet to save words or to be hip, or whatever.
A faster transfer variation of XMODEM. In YMODEM, XMODEM's 128-byte block grew to YMODEM's 1024 bytes (1 kilobyte). YMODEM combines the 1K block and the 128-byte block modems into the same protocols. YMODEM, or 1K as it is known, became the thrifty way to send files (i.e. it saved on phone time). Enhancements were added, such as auto-fallback to 128-byte blocks if too many errors were encountered (because of bad phone lines, etc.) See XMODEM for a much larger explanation of file transfer using X, Y and ZMODEM protocols.
Ymodem-g is a variant of Ymodem. It is designed to be used with modems that support error control. This protocol does not provide software error correction or recovery, but expects the modem to provide it. It is a streaming protocol that sends and receives 1K packets in a continuous stream until told to stop. It does not wait for positive acknowledgement after each block is sent, but rather sends blocks in rapid succession. If any block is unsuccessfully transferred, the entire transfer is canceled . See also ZMODEM, which we prefer.
YB. A combination of the homonymic Greek "iota," referring to the last letter of the Latin alphabet, and the English "bite," meaning "a small amount of food." A unit of measurement for physical data storage on some form of storage device-hard disk, optical disk, RAM memory etc. and equal to two raised to the 80th power, i.e. 1,208,925,819,614,600,000,000,000 bytes. Here are the others in the chain:

MB = Megabyte (2 to the 20th power)
GB = Gigabyte (2 to the 30th power)
TB = Terabyte (2 to the 40th power)
PB = Petabyte (2 to the 50th power)
EB = Exabyte (2 to the 60th power)
ZB = Zettabyte (2 to the 70th power)
YB = Yottabyte (2 to the 80th power)

Year over year. Yoy is a financial measure. It might be used thus: What earnings are like today, compared with what they were a year ago for the same period ” e.g. a quarter, six months, etc.
The phrase Yuppie came into being as a clever twist on several words and phrases. The abbreviation Y.U.P. ” Young Urban Professionals or Young Upwardly mobile Professional ” was used at least since the late 1970s by public opinion analysts. This abbreviation fit the patter of the first syllable of two other lifestyle words that had been around since the 1960s, hippie and preppie - so it was natural to add the '-pie' suffix to 'yup' as well. See also DINK.
Crisp $20 bills that spew from ATM machines. Often used to split the bill after a meal. "We all owe $8, but all anybody's got is yuppie food coupons." A Wired Magazine definition.
A Mongolian circular shed. Some companies are making Yurt-like sheds for installation in the back yards of telecommuters ” especially those telecommuters who don't have enough room inside for a home office.
A color encoding scheme for natural pictures in which luminance and chrominance are separate. The human eye is less sensitive to color variations than to intensity variations. YUV allows the encoding of luminance (Y) information at full bandwidth and chrominance (UV) information at half bandwidth.
The color encoding scheme used in Indeo Video Technology. The YUV9 format stores information in 4x4 pixel blocks. Sixteen bytes of luminance are stored for every one byte of chrominance. For example, a 640x480 image will have 307,200 bytes of luminance and 19,200 bytes of chrominance.
