List of Farm to Market Roads in Texas (1–99)

Farm to Market Roads in Texas are owned and maintained by the Texas Department of Transportation (TxDOT).

FM 1

Farm to Market Road 1 (FM 1) was the first farm-to-market road to be designated in Texas, at the request of local industry for a paved road. The 18.6-mile (29.9 km) road provides access to rural areas of East Texas from U.S. Highway 96.

FM 2

Farm to Market Road 2 is a farm to market road in rural southeastern Grimes County, Texas. FM 2 was designated on July 29, 1941.

FM 2 begins in the village of Courtney, at a county road near the Washington County line. It runs along the northeastern edge of the TDCJ O.L. Luther Prison Unit. It then continues through rural farmland in Grimes County. It then travels east, crossing SH 6 and passing several prison farms before ending at FM 362.

FM 2 was designated in 1941 from Courtney east to SH 6. The designation was extended to FM 362 on May 2, 1962, which added approximately 4.4 miles to FM 2.

FM 3

Farm to Market Road 3 is a farm to market road in southwestern Leon County, Texas. FM 3 was designated in March 1942.

Radio

Radio is the use of radio waves is to carry information, such as sound, by systematically modulating some property of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form.

Radio systems need a transmitter to modulate (change) some property of the energy produced to impress a signal on it, for example using amplitude modulation or angle modulation (which can be frequency modulation or phase modulation). Radio systems also need an antenna to convert electric currents into radio waves, and vice versa. An antenna can be used for both transmitting and receiving. The electrical resonance of tuned circuits in radios allow individual stations to be selected. The electromagnetic wave is intercepted by a tuned receiving antenna. A radio receiver receives its input from an antenna and converts it into a form usable for the consumer, such as sound, pictures, digital data, measurement values, navigational positions, etc. Radio frequencies occupy the range from a 3 kHz to 300 GHz, although commercially important uses of radio use only a small part of this spectrum.

ABC

ABC are the first three letters of the Latin script known as the alphabet.

Facebook structure

News Feed

On September 6, 2006, Ruchi Sanghvi announced a new home page feature called News Feed. Originally, when users logged into Facebook, they were presented with a customizable version of their own profile. The new layout, by contrast, created an alternative home page in which users saw a constantly updated list of their friends' Facebook activity. News Feed highlights information that includes profile changes, upcoming events, and birthdays, among other updates. This has enabled spammers and other users to manipulate these features by creating illegitimate events or posting fake birthdays to attract attention to their profile or cause. News Feed also shows conversations taking place between the walls of a user's friends. An integral part of the News Feed interface is the Mini Feed, a news stream on the user's profile page that shows updates about that user. Unlike in the News Feed, the user can delete events from the Mini Feed after they appear so that they are no longer visible to profile visitors. In 2011 Facebook updated the News Feed to show top stories and most recent stories in one feed, and the option to highlight stories to make them top stories, as well as to un-highlight stories. In response to users' criticism, Facebook later updated the News Feed to allow users to view recent stories first.
