Allocating directory rights with chmod

What is chmod?

With Linux, access rights for directories and files are often set through the terminal where file owners can be defined and groups can be assigned. With the ‘chmod’ command, user classes can be assigned certain file rights. Access rights in the Unix file system can be changed in two different ways: symbolic or numeric. Find out more about both notation types here.

Introduction to TCP

TCP (Transmission Control Protocol) – The transmission protocol explained

Life without networks, especially the Internet, is unimaginable nowadays. Interconnected servers, PCs and mobile devices are virtually indispensable at home and at work. However, most of us know very little about the fundamentals of these networks. All the more reason to take a closer look at the Transmission Control Protocol (TCP), the central control component for data transmission.

LAN

LAN – Local Area Network: The Technology at a Glance

LAN is often used in relation to setting-up internet access and providing data for multiple end devices. But many users aren’t familiar with what a LAN actually is and how it differs from WLAN, nor whether a LAN is indeed relevant for them. Our article answers the most important questions.

WAN

What is a WAN (Wide Area Network)? The Technology at a Glance

Anyone who deals with networks will come across the term WAN (Wide Area Network) sooner or later. Lots of people confuse WAN with WLAN or LAN. But a Wide Area Network clearly differs from these two other network types. We explain what a WAN is used for, how it’s structured, and compare it with related networks.

We answer the most important questions regarding WebDAV and explain, among other things, how it enables users to create and move documents on servers.

CPU Usage

High CPU usage: What does this mean?

CPU usage plays a crucial role with respect to your PC’s processing power and speed. If it is too high, then commands will not be processed as is ideal and all processes will run much slower. But when is high processor usage normal and when should countermeasures be utilized? And how does one even figure out the relevant values?

CPU Temperature

The CPU temperature: How high can it get and how can you monitor it?

The CPU temperature primarily depends on the processes that are running, though factors such as ambient temperature also play an important role. Since fluctuations are quite normal, only sustained overheating needs to be prevented. There are different tools with which you can display the CPU temperature in order to be sure that it stays within the normal range and that your computer operates...

BIOS beep codes

BIOS Computer beep codes

If your computer suddenly beeps during start-up for no obvious reason, the BIOS may be trying to tell you something. Beep codes indicate problems with hardware or connection issues between different computer components. But what do all of the various beeps mean? We’ve put together a table that shows which system error different types of beeps corresponds to.

How to Overclock CPU

How to overclock your CPU: fine-tuning for your processor
