One can argue that the development of the RJ45 interface is the actual broadband reason. The original RJ45 – where ‘ RJ ‘ stands for “registered Jack”-was used to connect the first modems with the telephone network in the 1970s. Over the years, the basic RJ45 was changed a little bit and became the standard interface for computers ‘ connection to networks and later to the Internet.
Today there are a number of RJ modules designed to connect the various networks. The RJ45 is a standard cable today and is used to connect through the ethernet cable to the Ethernet port on your computer. This is absolutely fundamental to the technological basis for the creation of broadband. Now, therefore, we can move the focus to the introduction of broadband internet and what this technology can achieve to progress to our times.
The first email was sent from a modem in 1970 – through an RJ45 that was connected to the Internet telephone network. It was only in the 1980 ′s that the modem became more common, and although these devices were designed to transmit data up to 56Kbps (kilo bits per second), the average phone line was only able to transmit up to 38Kbps. Most of us Remember that it took eons with the connection through the telephone network.
And in addition to being painfully slow, the main drawback of this dial-up connection was that a single phone line could only be used for a modem transmission or phone call – and it was not possible to use both services at the same time. Outlets tended to install two phone lines – one of which was dedicated to calls and the other phone line was exclusively dedicated to the modem and the Internet connection. But due to the cost of installing another line, modems were seldom used in addition to the most necessary in private context.
Such continued Internet connection to act up to the mid-1990s, when Digital subscriber Line (DSL) technology was truly developed and made it possible to use both Internet access and telephone conversations through the same phone line and then on Same time.
And although broadband in US geeks the world has many different definitions, this is the duality of DSL technology that most ordinary users associate with broadband. In slightly more technical terms, broadband refers to the bandwidth frequency used for data transmission, ie. Simply say that the greater the frequency bandwidth you have, the more data it is possible to send per second.
