It was 1975.
Ethernet has access any time it is desired to transmit. It listens first to ensure no other nodes are communicating. If clear, they transmit. Yes, collisions are normal - If two nodes collide (transmit at the same time), they both back off, send a jamming signal, wait a "random" amount of time (based on their MAC address), and resend.
While the wireless or radio was invented in 1895, it was not used for entertainment until about 1920. The first radio station was started in Pittsburgh, PA in 1920 with commercial radios beginning sales about that time.
The radio's appearance has definitely changed over time. The newest radios are very small compared to the big and bulky radios of the past.
Not on a normal radio. Such radios are designed to receive only the signal of the frequency that they are tuned into. Different stations transmit on different frequencies so a radio will only pick up one at a time.
Serial ports transmit data one bit at a time, which is why they are becoming obsolete.
No, there were no radios in Victorian times, as the Victorian era spanned from 1837 to 1901, and the invention of radio technology did not occur until the late 19th century. The first practical radio transmissions began in the 1890s, after the Victorian era had already ended. However, during this time, other forms of communication, such as the telegraph, were in use.
Nobody knows when the exact date is but the very first time that we know is when The Beatles first met Bob Dylan was the first time they experimented with marijuana.
Wen she waz 47 sec old.
Haha, they couldn't have know the exact time... because before the clock... there was no time :p
The first animal life on Earth was in the ocean in the Precambrian time. The exact nature of the first animals is not known as the fossil record from that time is incomplete.
The extent to which radios have impacted our lives is expansive. The radio was the first means of communicating verbally over vast distances in a short amount of time. Before, telegrams and handwritten letters were the mainstays of communication. It also furthered the development of Wave technology, which leads to television, and microwaves. in many ways, the modern world would not be the same without radios.
