IP addresses provide an identification and address to devices in a network so that they can communicate with other devices. These IP addresses need to be unique so that the device can be uniquely identified with in the network. Historically, Internet Protocol (IP) version 4 (or IPv4) was used to assign addresses. As the number of devices and networks on…
Many times softwares are hosted on ftp servers, especially open source and not so popular ones. FTP servers are also good method to transfer files and folder between machines. This means that you will need to occasionally connect to FTP file servers either to download or upload files. If you happen to work with FTP servers a lot, then it…
Depending on the network you are connected to, you may need to configure a proxy server in order for you to connect to the internet. A proxy server is not a part of every network and is not a required component of a network. Large networks, such as corporate networks usually have a proxy server that allows the network traffic…
One of the most popular methods of transferring files between machines is using a FTP server and client. There are quite a few FTP servers out there, and almost all of the Linux distros comes with one by default. If you are not happy with the one that is installed by default, you can always install another one. By default,…
One of the best ways to connect to a remote machine is by using the ssh protocol. Secure Socket Shell (or ssh) is a cryptographic network protocol that allows you to securely connect to a remote machine. It also refers to a suite of utilities that implement the protocol, such as the ssh server and an ssh client. In order for…
Network Routers are an integral part of your home network. Most applications and services works without having to open up ports on your router. But sometimes there are some applications, such as multiplayer games, p2p networks and web servers that necessitates the need for certain ports to be open or forwarded so that they can function correctly. The network router…
It is very likely that you already use a network router to handle your home network. A network router gives you the ability to manage and configure both the wired and the wireless network on a local scale, usually for work or home. A wireless local area network (called WLAN) allows to link multiple devices and to a wider area…
The most important factor in Search Engine Optimization (SEO) is the overall page loading time. If you have a fast loading page, then you might be able to get away with a lot of other issues. As you might already know, most of the SEO optimizations are geared towards making the webpage load faster. One of the performance bottleneck could…
A port in computer networking refers to a communication end point on a particular machine. It is associated with one machine or an IP address and is used as a communication mechanism between two or more machines. A port is said to be open, when a software is actively using the port either to receive or to send data and/or…
The Linux operating system as well as many of the Linux applications use ports to communicate with each other. A port can be viewed as a communication endpoint that is identified by a number called the port number. This port number along with the address of the machine is used by other applications to communicate with an application (or process)…
Data Compression or compressing of your files and folders do have many advantages. It is a process by which the resources such as disk space and network time can be conserved by reducing the overall size of the files. There are several reasons as to why you might want to compress the files and folders, several of which are good….
Data compression is a process by which the file size is reduced by re-encoding the file data to use fewer bits of storage than the original file. The original file can then be recreated from the compressed representation using a reverse process called decompression. There are several different algorithms and implementations that allow you to compress your files, some of which…
