Happy birthday TCP/IP! We ACKNOWLEDGE you. Transmission Control Protocol. Internet Protocol. The deployment of TCP was the birth of the modern Internet — it was the same protocol still in use today. But before TCP, IP networks still had a standard way to communicate: NCP, Network Control Program. It was warty and problematic and limited, →
Finland seized an oil tanker after the latest in a series of disruptions to undersea power and telecom infrastructure. Four telecommunication cables connecting Finland out of service. Finnish authorities board a ship in the Baltic Sea that the West suspects is linked to Russia, a day after an underwater Finland-Estonia electricity cable was cut and →
LAN iSilencer Audiophile Ethernet Dongle Claims to ‘Quiet Your Network’ article says that at ‘just’ $100, it seems like a “bargain” compared to some audiophile Ethernet cables. iFi-Audio has released the LAN iSilencer, an audiophile accessory which aims to “quiet your network.” According to the Ethernet dongle designers in Japan, this product removes digital signal →
One day I came across a device called “Ethernet Network Isolator” and started to wonder why we would need such device as standard Ethernet system that uses twisted pair cable and RJ-45 connectors is already isolated from both ends of the cable (isolation transformers that can withstand 1500V). When the network connections made with unshielded →
A fiber-optic cable, also known as an optical-fiber cable, is a cable that is one or more optical fibers that are used to carry light. The optical fiber elements (typically made of glass) are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable is used. →

Everybody knows how Internet goes through copper wiring, fiber optics and wireless? But are the other communications media that could be uses? Yes there seems to be some unexpected ways to transport data. A core part of the hacker mentality is the desire to test limits: trying out ideas to see if something interesting, informative, →
Who remembers Phone booths and above all phone cards? Phone cards were a technological advance in the world of public telephone traffic in the 1990s. They allowed to make calls on many phone booths in Finland and phone cards were also a popular collector’s item, collected both used and unused: Telecom companies have placed advertising →
TCP/IP was born in this day 50 years ago when the editors of IEEE Transactions on Communications received a manuscript from Vint Cerf and Bob Kahn which described a method for sending packets across networks. Exactly which day Cerf and Kahn’s manuscript was received by the IEEE editors is not clear (it was either November →
A modem, short for “modulator-demodulator,” is a device that converts digital data from a computer or other digital device into an analog signal that can be transmitted over analog communication lines, such as a telephone line. The term Modem Definition is an acronym for modulator-demodulator. The primary modem function is to convert digital data into →
