Clearing the cache: deleting the browser’s cache

Information is often cached so that visited website can be loaded quickly and videos and gifs can be viewed offline. However, if the cache contains a large, or very large amount of data, it can cause problems and adversely affect computer performance. Therefore, it makes sense to delete the cache from time to time.

Linux vs. Windows: a comparison of the best web server solutions

The duel between Linux and Windows may have an obvious victor on the home computer front, but the battle for server use paints a very different picture: since the beginning, Linux has bested Windows, as usage figures show. But many users remain unconvinced by statistics and rightfully ask the question: what are the actual differences between the two platforms?

What are rainbow tables?

Rainbow tables: they may sound innocent, but they’re actually a strong attack method for cybercriminals. Using rainbow tables, you can find out specific passwords in just a few seconds. To protect yourself and your users from such attacks, you should understand how the tables function. We explain rainbow tables using an example.

Unix: the operating system setting new standards

In the context of open source operating systems, the term “unixoid” is often used, indicating that the software is similar to the Unix system published in 1969. Typical indicators are, for example, the file system, or means and rights available to access the system and its processes. But what exactly is Unix, and who is behind the development of this influential operating system?

What is Internet Protocol (IP)?

When networking a computer system, protocols play an important role. An example is the Internet Protocol, which was published in a first specification in 1981, and is the indispensable basis for the smooth sending and receiving of data packets. But what is behind the RFC standard? And how does the internet protocol actually work?

Windows blue screen (BSOD): How to cure the error

The infamous blue screen of death usually shows up without any warning. It’s an important indicator of internal problems with hardware, software, or drivers. If Windows can no longer be run as a result of such a problem, then the forced shutdown takes place in the form of a blue screen containing an error message. This may cause unsaved files and documents to be lost. The most important thing with...

Ethernet frame: definition and variants of the frame format

Ethernet frames enable the transmission of data over an Ethernet connection and are essential for local area networks. Ethernet frames are structured and sized differently depending on the protocol, and contain important information such as MAC addresses, protocol information, length information, and much more. The established Ethernet standard IEEE 802.3 has also developed special frames for VLAN...

Windows command prompt: CMD commands explained

There are more than 200 CMD commands available with Windows. The command prompt can be used to control large parts of the operating system, computer, or drives. You can also use the Windows “command prompt” commands to organize your files or run network tasks. To do this, though, you have to know the right commands. Here we explain how to use CMD commands and which functions they have. Our article...

What is Ethernet (IEEE 802.3)?

In the beginning, there was ARPANET and ALOHAnet. Then Ethernet followed as a groundbreaking innovation for local networks. Ethernet enabled collision-free interconnection of multiple devices via a common bus. For the first time, data packages could efficiently be exchanged between individual devices. Today, the technology is extensively used in the standard IEEE 802.3. With fiber optic cables,...

Make a bootable USB drive and save your computer

Optical installation media are yesterday’s news. A bootable USB drive is not only faster and more practical than a CD-ROM, it can also do a lot more: For example, create a portable operating system with which you can use Windows as well as Linux computers. The most important function, though, is the ability to boot and repair a PC following a serious system problem. To make such a bootable USB...
