When was LAN invented?
LANs were developed in the 1960s for use by colleges, universities, and research facilities (such as NASA), primarily to connect computers to other computers.
Who discovered local area network?
In the 1960s and 1970s, networks were ad hoc hodgepodges of technologies with little rhyme and less reason. But then Robert “Bob” Metcalfe was asked to create a local-area network (LAN) for Xerox’s Palo Alto Research Center (PARC). His creation, Ethernet, changed everything.
Why was LAN created?
LANs allowed for the transmission of data between workers. In turn, they enabled this shared data to be directed to a common printer, serving a larger group of users. This eliminated the need for each worker to have a printer and ensured that the one printer provided was not underutilized.
What is the first local area network?
In the 1960s, large colleges and universities had the first local area networks (LAN). In the mid-1970s, Ethernet was developed by Xerox PARC (Xerox Palo Alto Research Center) and deployed in 1976. Chase Manhattan Bank in New York had the first commercial use of a LAN in December 1977.
What is local area networks?
A Local Area Network (LAN) is a group of computers or other devices interconnected within a single, limited area, typically via Ethernet or Wi-Fi.
How Ethernet LANs have changed over the years?
Over time, Ethernet has largely replaced competing wired LAN technologies such as Token Ring, FDDI and ARCNET. The original 10BASE5 Ethernet uses coaxial cable as a shared medium, while the newer Ethernet variants use twisted pair and fiber optic links in conjunction with switches.
What is the meaning of LAN?
local area network
A local area network (LAN) consists of a series of computers linked together to form a network in a circumscribed location. The computers in a LAN connect to each other via TCP/IP ethernet or Wi-Fi. A LAN is normally exclusive to an organization, such as a school, office, association or church.
What are the examples of local area network?
Examples of Local Area Network (LAN)
- Networking in home, office.
- Networking in school, laboratory, university campus.
- Networking between two computers.
- Wi-Fi (When we consider wireless LAN).
How does a local area network work?
A local area network (LAN) consists of a series of computers linked together to form a network in a circumscribed location. The computers in a LAN connect to each other via TCP/IP ethernet or Wi-Fi. A LAN is normally exclusive to an organization, such as a school, office, association or church.
What are the three main services used in a LAN?
Generally, LANs are made up of three layers: the access layer, distribution layer, and core layer.
Who designed or invented an Ethernet network for LANS in the year 1973 *?
2) In 1973, Bob Metcalfe invents the Ethernet network system at the Xerox Palo Alto Research Center (PARC). It was with Bob Metcalfe and his team at PARC that Ethernet first came to be. The goal of Metcalfe and his team was to develop a system to network PARC’s hundreds of different computers together.
