  • All about binary encoding: definition, decoder, encoder

    In the late 1930s, Claude Shannon showed that by using switches that close for "true" and open for "false," it was possible to carry out logical operations by assigning the number 1 to "true" and 0 for "false." This information encoding system is called binary. It's the form of encoding that allows computers to run. Binary uses two states (represented by the digits 0 and 1) to encode information. This article discusses binary data encoding. You can find a binary decoder and encoder online.

  • What is 3-tier client/server architecture: example, diagram

    In client/server systems, there are several types of configurations. This article will get into detail of the client server architecture and more precisely, 2-tier architecture and 3-tier architecture. We also explain the differences and the similarities of the two systems.

  • URL manipulation attacks: example, measures

    The URL (Uniform Resource Locator) of a web application is the vector that makes it possible to indicate the requested resource. This article will show you how to protect yourself against URL manipulation attacks.

  • What is an FTP protocol: definition, commands

    What is FTP Protocol? FTP (File Transfer Protocol) is, as its name indicates, a protocol for transferring files. The implementation of FTP dates from 1971, when a file transfer system (described in RFC141) between MIT machines (Massachusetts Institute of Technology) was developed. Many RFCs have since improved the basic protocol, but the greatest innovations date from July 1973. The FTP protocol is currently defined by RFC 959.

  • How to make an RJ45 crossover cable: steps, tools

    A network card may have several types of connectors, with the most common being an RJ45 connector and a BNC connector (coaxial cable). In this article, we talk about the RJ45 ethernet crossover cable, as it is the most widely used.

  • What is the WiMAX technology: vs WiFi, LTE

    What is WiMAX? WiMAX stands for Worldwide Interoperability for Microwave Access. It is a metropolitan wireless standard created by Intel and Alvarion in 2002 and ratified by the IEEE (Institute of Electrical and Electronics Engineers) under the name IEEE-802.16. More precisely, WiMAX is the commercial designation that the WiMAX Forum gives to devices that conform to the IEEE 802.16 standard to ensure a high level of interoperability among them.

  • What are serial and parallel ports and how do they work?

    Every computer is built with tons of different ports that perform various functions. Two of the most important types of data trans are serial ports and parallel ports. This article discusses the differences and similarities between the two types of ports.
