Smoke Signal

Ancient form of visual communication where people use smoke from a fire to send messages over long distances

Homing Pigeon

Pony Express

A fast, historical mail service in the United States. It used relay teams of horse-mounted riders.

Semaphore Flag

A visual signaling system that uses two hand-held flags to spell messages letter by letter

Telegraph

A method of sending text messages over long distances using electrical signals sent through wires

Telephone

The transmission of human voice and sound signals in real time between two or more people separated by distance, using electrical wires, radio frequencies, or digital networks

Radio

The wireless sending and receiving of information—such as voice, music, pictures, or data—using invisible electromagnetic waves that travel through the air

Email

The digital exchange of written messages, files, and media between people using electronic devices connected to a network

Computer networks

Also known as datacom or data-transmission networks, represent a logical result of the evolution of two of the most important scientific and technical branches of modern civilization - computing and telecommunications technologies

1940

George Stibitz used a Teletype machine to send instructions for a problem set from his model at Dartmouth College to his Complex Number Calculator in New York and received results back by the same means

1950

Military radar system Semi-Automatic Ground Environment (SAGE)

1960

Semi-automatic business research environment (SABRE) went online with two connected mainframes

1962

Linking output systems like teletypewriters to computers was an interest at the Advanced Research Projects Agency (ARPA) when, JCR Licklider (hahahahaha) was hired and developed a working group he called the Intergalactic Computer Network. It allowed the data and programs stored within each computer to be accessed from anywhere in the world by any of the computers connected to the network

1964

Researchers at Dartmouth developed the Dartmouth Time Sharing System for distributed users of large computer systems. At the same time, the Massachusetts Institute of Technology was supported by General Electronic and Bell Labs used a computer to route and manage telephone connections

1965

Thomas Marill and Lawrence G. Roberts created the first WAN. The first widely used telephone switch that used true computer control was introduced by Western Electric

1977

Commercial services using X.25 were deployed, and later used as an underlying infrastructure for expanding TCP/IP networks

1991

Home Broadband created

1996

56K modem was invented by Dr. Brent Townshend

2000

Cisco achieved a stock market capitalization of more than 550 million dollahs that made Cisco the single most valuable corporation in the worked at that time, literally making it a “Fortune 1” company

2001

Home broadband enters mainstream usage and begins growing at a faster rate than Internet dial-up services

2009

10 Gigabit Ethernet (GE) was the only market segment to show sequential port and revenue growth in 2009

2010

100 GE standard fully completed

2020

Terabit Optical Ethernet Center are aiming for 1 Terabit Ethernet over optical fiber
