Due to increasing globalization, processes for connecting and networking digital infrastructures are becoming increasingly important. The remote procedure call (RPC) plays a key role in this context, as it enables efficient inter-process communication designed for task distribution in networked client-server architectures.
Cyber criminality is a big issue for most companies’ IT departments. Online attacks threaten the security of private networks and cause millions of dollars of damage per year. Popular targets are servers that provide online services and therefore require a permanent internet connection. An extra layer of security can be applied by using an upstream network component – the reverse proxy. This...
Virtual machines are extremely practical and versatile: Do you want to set up an isolated test environment, run a Linux application on your Windows computer, or provide different operating systems for cross-platform software tests? With the right virtualization software and an appropriate image file, this is easy. We will introduce you to the basics of hypervisor-supported hardware virtualization...
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...
Without TCP/IP protocols, you wouldn’t be able to read the words on this page. TCP and IP, the two foundational protocols of the suite, along with other related sets of rules, define how computers communicate over the Internet and other networks. In fact, the standards are so established that every device on the Internet follows these protocols to ensure the smooth transfer of data.
If you’re developing a website, it’s important to regularly ensure that all the elements function as intended. Although there are no specific tools required for creating a basic info page with static content, it’s not possible to preview a project containing dynamic elements without some additional tools. The simplest solution is to use an all-in-one development environment like MAMP.
Whether on mobile or on your PC, being able to access address and contact details is important for personal and professional reasons. With CardDAV, contact information can be stored and synchronized across different devices and accessed by multiple users. But what is CardDAV, how does the network protocol work and what benefits does it offer?
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.
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 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.
