Telephone
The telephone was an invention that made it possible to communicate with voices using a wire. The telephone was invented by Alexander Graham Bell and Thomas A Watson in 1876. This was significant because it allowed people and businesses to communicate quickly. In 1880, almost 49,000 telephones were used and by 1910, nearly 5.8 million were being used. -
Television
The television made it possible to broadcast video over a wire. Philo Farnsworth invented the first completely electronic television in 1927. Early televisions were very rare because of the high cost. Eventually the prices fell in the 1950's and many Americans were able to purchase a television set. Today, almost every household in America has a colored television. Nielsen Holdings estimates that 96.1 percent of U.S. citizens have access to television. -
Microprocessor
A microprocessor is a computer processor that is on an integrated circuit. The world's first microprocessor was the Intel 4004 and was made by Ted Hoff, Stanley Mazor, and Federico Faggin. Microprocessors are important because they allow computers to be included in everyday items such as cell phones, traffic lights, ATM's, etc. The Intel 4004 had a clock speed of 740 kHz with 2250 transistors. The new AMD Zen 3 (2020) has a clock speed of 3.4-4.9 GHz with 4.15 billion transistors -
Email
Email allows you to send and receive mail electronically. The first email that was sent across a network was Ray Tomlinson in 1972. Email allows someone to send and receive messages from anyone with an email address. Email allowed you to send a message to the users inbox when they weren't there, unlike the telephone. Today, there are over 3.8 billion email accounts in the world. -
