Debian is a Linux operating system, a popular and influential distribution among the Linux distributions that are free under the GNU license. The Debian operating system can be used as a desktop operating system but also for an enterprise server environment. A feature that is specific to the Debian distribution is the fact they divide updates into versions. At any given moment there are three...
In order to save resources, internet providers usually use dynamic IP addresses to allocate to individuals, which change over time. Because an Internet provider has a limited number of public IP addresses, and to get as much out of these public addresses, it uses an address reallocation scheme that takes the IP from idle clients do not use at any given time, to other clients who want to sign in...
Ubuntu Tweak is an app that allows us to configure a Ubuntu system and desktop in an easy and fast way. It has the following characteristics: 1. It facilitates the installation of new applications, from a large list that is frequently updated in which applications can be sorted into categories. 2. The ability to “clean the system” as unused and remove remaining packages, as well as...
Regardless of the operating system you want to install on your computer, there is something that every OS has in common and those are partitions. There are several advantages to having multiple partitions on the HDD, such as separating the operating system from user files, creating a swap partition, run and store multiple operating systems on each partition. Gparted is the GNOME partition editor...
NAT is a procedure through which the IP header of data packages is changed to convert the source IP address from one destination to another. Currently, the most common use for NAT is mapping multiple private addresses to a single public address. This is known as PAT or port address translation and can also come by the name of NAPT which is network address port translation. NAT is an acronym for...
When a machine wants to send a packet on an Ethernet network, it has the IP address but not the MAC address of the receiving machine, but for the data to be transmitted to the destination the MAC address is needed. The protocol that determines the MAC address from the IP address is called ARP. Address Resolution Protocol (ARP) is a tool that allows devices to communicate when they do not have all...
In this article, we talk about subnetting an IPv4 network. More specifically, we will find out of which IP addresses a network is formed, what size can a network have and how. Both IPv4 and IPv6 addresses use subnetting, which consists of splitting the IP address into two parts: the network address and the station address. Using a network mask, the computer can determine where to divide the IP...
TCP is an acronym for Transmission Control Protocol and it ensures management and control for data transmissions. It is a protocol that belongs to Layer 4 of the OSI model, more precisely the Transport level. TCP is a protocol that we use at all the time without realizing it. For example, when we download a file from the Internet, or access a web page or connect in any way to a network device, we...
