  • HTML document layout

    HyperText Markup Language (HTML) is based on the SGML (Standard Generalized Markup Language) metalanguage and is the format of the World Wide Web documents. An HTML page is a simple file containing text formatted with HTML tags. A web page can be built from even the most basic text editors, such as Notepad++. There are also HTML editors which display tags, attributes, and their values in different colors to make them easier to read.

  • What is a network card?

    A network card (also called a network adapter, network interface card, or NIC for short) acts as the interface between a computer and a network cable. The purpose of the network card is to prepare, send, and control data on the network. In this article, we will introduce this component.

  • How to edit, modify, restore the hosts file?

    The hosts file (/etc/hosts on Unix based system) is the first step in the translation of a FQDN hostname to the IP address format. When making a DNS request on any address server on the web, this file is queried first. For each name present in this file, a connection will be opened to the defined IP address. It works just like a telephone directory.

  • How to create a Local Area Network (LAN)?

    When you have several computers, it can be convenient to connect them to each other to create a Local Area Network (LAN). Setting up such a network is a simple process shown in this article.

  • Computer buses: ISA, MCA and VLB, differences

    Expansion buses (sometimes called peripheral buses) have connectors that allow you to add a computer's expansion cards (peripherals). Different types of standard internal buses are characterized by their shape, the number of connector pins, and the type of signals (frequency, data, etc.). Read on to learn more about computer buses.

  • FAT16 and FAT32: characteristics and differences

    The first file system to be used in a Microsoft operating system was the FAT system, which uses a file allocation table. This table is an index that creates a list of disk contents to record the location of files on the disk. Since the blocks that make up a file are not always stored contiguously on the disk (a phenomenon called fragmentation), the allocation table allows the file system's structure to be maintained by creating links to the blocks that make up the file.

  • Everything about WPAN: Wireless Personal Area Network

    A Wireless Personal Area Network (WPAN for short) is a low-range wireless network that covers an area of only a few dozen meters. This network is generally used for linking peripheral devices (like printers, cellphones, and home appliances), a PDA to a computer, or just two nearby computers without using a hard-wired connection. There are several kinds of technology used for WPAN.

  • Agile software development methods

    Agile methods software development (also called Agile Modelling, denoted AG for short) reduce software lifecycle time (thus speeding up development) by firstly creating a prototype version, then integrating functionality on an iterative basis responding to customer requirements and testing throughout the development cycle.

  • Sound card connections and color codes

    A sound card (also called an audio card) is the part of a computer that manages its audio input and output. Nowadays, computers usually have it integrated into their motherboard. In this article, we will introduce this critical component.

  • Data transmission cables: types, speed

    The transmission medium is the physical vehicle that facilitates the transport of information. Guided transmission media use a solid medium (cable) for transmission. There are many cables, but the most common are Coaxial cable, Double twisted pair, and Optical fiber. In this article, we'll provide an introduction to each of them.
