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...
One of the most important things, when you have a website, is to make sure you have a backup of it to recover from if something unexpected happens. And there are many unforeseen things that can happen: the website may be compromised, the web hosting provider may no longer be trustworthy (whether they are deleting your account if you somehow violate the terms and conditions or have a catastrophic...
It’s easier to prevent than to heal, and that’s why we need to mention – even now – that it’s imperative to have a backup with all the data in your web hosting account. It is said that there are two categories of people: those who back up their data and the ones that will need a backup of it. However, if you are in the unfortunate situation of completely losing the...
Are you prepared for a situation when your website might is compromised? What if you delete a picture or an article by mistake? What if a platform update fails? For all these situations the answer is: make a backup. Your web hosting provider should typically have a backup of your data. In this article, we will focus on the actions you can take, as a web hosting client, to be covered in various...
The OSI model is a framework that defines how different types of digital equipment communicate across a network. This model is divided into seven layers, each one being independent of the other. The OSI Reference Model, OSI being an acronym for Open Systems Interconnection is a stack of hierarchical communication protocols very often used to build a computer network. OSI is a standard of the...
VoIP is an acronym for Voice over Internet Protocol, also called IP Telephony or Internet Telephony and can be defined as the process of transmitting voice conversations through IP data connections or digital networks where this protocol is used. There are three main categories of traffic on the Internet: 1) Data Traffic 2) Voice Traffic 3) Video Traffic VoIP is a technology that gives us the...
