Understand The Origin of Computer Network Communication

Today, you can connect multiple devices so they can talk to each other, exchange information, and work securely and seamlessly. And the professional who specializes in computer network communication is the one who makes everything work in harmony.

To make this possible, during graduation, he develops various skills in the area related to disciplines such as computational mathematics, computer architecture and even project management. Besides, you need to understand the origin of computer network communication. Find more information about the computer network architect definition and career opportunities.

Did you find the idea of ​​knowing how it all started interesting? Here’s a little more about how technology emerged and evolved until the professional became so important in the job market.

The origin of computer networks:

It all started around 1960 when communication took place over the telephone network. During this period, micro and minicomputers of good performance were developed. But there was no way to unite these machines, and there was a growing need to share information between users from different regions.

Several researchers began their studies at this time at MIT, the Rand Institute, and the National Physical Laboratory. The union of the three works gave rise to the ARPA (Advanced Research Projects Agency) project, which gave rise to ARPAnet, the precursor of the world’s largest network, the Internet, was the first computer network in the world.

The first computers were called interface message processors (IMPs). The same year the man stepped on the moon in 1969, the first IMP was installed at the University of California, with three additional IMPs.

In 1970, new packet computing networks began to emerge, such as ALOHAnet, the microwave radio network linking the islands of Hawaii, and TELENET, the ARPAnet technology-based commercial package interconnection network.

The number of small networks was growing so much that Robert Metcalfe introduced the principles of a local network, ETHERNET, which later gave rise to short-range LANs, under the supervision of DARPA (Advanced Defense Research Projects Agency).

During this period, the TCP (transmission control protocol) was also created, responsible for sending the packets sequentially and reliably. Over time, the service was modified, and TCP was responsible for organizing the arrival of packets, while IP has the send function, and UDP controls the voice flow.

By the end of that decade, about 200 computers were already connected to ARPAnet, mainly because it was used for communication between the military during the Cold War. After this time, ARPAnet was no longer interesting to them and was transferred to universities.

That was when researchers began transmitting this communication to other nations, reaching 100,000 machines on the network at the end of the 1980s. Thus a large worldwide network was formed, which began to be called the internet. After that, in 1983, the TCP / IP protocol became official and became mandatory on all computers.

It was also around this time that NSFNET, the primary backbone that provided access to other computing centers, and the Domain Name System (DNS), which made it easier to memorize addresses and letters, came about.
