Area Code 707
Area code 707 is a telephone area code in the North American Numbering Plan (NANP) for the northwestern part of the U.S. state of California. It was created by a split of area code 415 on March 1, 1959. It serves part of the northern San Francisco Bay Area, as well as the North Coast. Major cities in the area code include Napa, Sebastopol, Vallejo, Benicia, Fairfield, Santa Rosa, Windsor, Healdsburg, Rohnert Park, Petaluma, Fort Bragg, Rio Vista, Crescent City, Eureka, Clearlake, Vacaville, Dixon, and Ukiah. History When the North American Numbering Plan was created by AT&T in 1947, the far northern part of California received area code 916, with the exclusion of the city of Sacramento, which used area code 415. California area codes were reorganized geographically in 1950, so that 916 was assigned to a numbering plan area that comprised only the northeastern part from the Sierra Nevada to the Central Valley. The coastal area to the west was assigned area code 415. With t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telephone
A telephone is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be easily heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals that are transmitted via cables and other communication channels to another telephone which reproduces the sound to the receiving user. The term is derived from el, τῆλε (''tēle'', ''far'') and φωνή (''phōnē'', ''voice''), together meaning ''distant voice''. A common short form of the term is ''phone'', which came into use early in the telephone's history. In 1876, Alexander Graham Bell was the first to be granted a United States patent for a device that produced clearly intelligible replication of the human voice at a second device. This instrument was further developed by many others, and became rapidly indispensable in business, government, and in households. The essential elements of a telephone are a ...

Area Code 213
Area codes 213 and 323 are telephone area codes in the North American Numbering Plan (NANP) for the U.S. state of California. They are assigned to a numbering plan area (NPA) that comprises, roughly, the area of central Los Angeles, and includes several Southeast LA communities, such as Bell and Huntington Park. The area codes designated separate NPAs starting in 1998, when 323 was added, but were combined in an overlay plan into a single NPA in 2017. Previously, just downtown Los Angeles and immediately adjoining neighborhoods were served by area code 213, and the rest of central Los Angeles used area 323. Area code 213 is one of the original area codes created with the NANP in 1947, and was split five times over the decades. History In 1947, when the American Telephone and Telegraph Company (AT&T) devised the initial form of the North American Numbering Plan, the state of California was divided into three numbering plan areas: 213, 415, and 916, for the southern, central, and ...

Flash-cut
A flash cut, also called a flash cutover, is an immediate change in a complex system, with no phase-in period. In the United States, some telephone area codes were split or overlaid immediately, rather than being phased in with a permissive dialing period. An example is telephone area code 213, which serves downtown Los Angeles and its immediate environs, split in January 1951 into 213 and 714 all at once. Another example is an immediate switch from an analog television channel to a digital television channel on the same frequency, where the two cannot operate in parallel without interference. A flash cut can also define a procedure in which multiple components of computer infrastructure are upgraded in multiple ways, all at once, with no phase-in period. In film, an extremely brief shot, sometimes as short as one frame, which is nearly subliminal in effect. Also a series of short staccato shots that create a rhythmic effect.

Sierra Nevada (U
The Sierra Nevada () is a mountain range in the Western United States, between the Central Valley of California and the Great Basin. The vast majority of the range lies in the state of California, although the Carson Range spur lies primarily in Nevada. The Sierra Nevada is part of the American Cordillera, an almost continuous chain of mountain ranges that forms the western "backbone" of the Americas. The Sierra runs north-south and its width ranges from to across east–west. Notable features include General Sherman, the largest tree in the world by volume; Lake Tahoe, the largest alpine lake in North America; Mount Whitney at , the highest point in the contiguous United States; and Yosemite Valley sculpted by glaciers from one-hundred-million-year-old granite, containing high waterfalls.

Area Code 916
Area codes 916 and 279 are California telephone area codes that serve Sacramento, the state capital, and most of its suburbs. Area code 916 was one of the first three original area codes established in California in October 1947. It originally covered most of Northern California, but area code splits have reduced its coverage to the greater Sacramento area. Area code 279 began service in March 2018 to relieve an exhausted supply of telephone numbers in the 916 area code. History Originally, the plan area covered the far northern portion of the state. In 1950, as part of a realignment of California's area codes, 916 was rotated to cover the northeastern corner of California, from the Sierra Nevada to the Central Valley. This involved changing Sacramento from area code 415 to 916. The numbering plan area was split in a flash-cut on March 1, 1959, when area code 707 was created out of the northwest portion. On November 1, 1997, it was split again. The northeastern portion, includin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
