botond published 2024/02/17, Sat - 08:06 time
LTSP (Linux Terminal Server Project) is an innovative solution that allows several thin clients to run Linux-based applications using the resources of a central server. The LTSP initiative started in the late 90s and has continued to evolve ever since to meet the challenges of the modern technological and educational environment. The basic idea of ​​this project is simple but revolutionary: to reduce hardware requirements and maintenance costs while increasing the flexibility and scalability of the IT infrastructure.

Oracle VirtualBox (formerly Sun VirtualBox) is a free and open source virtualization software developed and maintained by Oracle Corporation. This software is designed to allow one or more operating systems to run within a single physical machine in the form of isolated virtual machines. VirtualBox is a widely used tool among system administrators, developers, and educational institutions because it provides a simple yet powerful solution for testing and running different operating systems simultaneously without changing the underlying physical hardware.

The Linux-based BIND (Berkeley Internet Name Domain) server is the most widespread and well-known DNS (Domain Name System) software, which is a key part of the basic infrastructure of the Internet. BIND's development began at the University of Berkeley in the late 1980s, and since then it has undergone many developments to meet today's challenges. As a DNS server, BIND's main task is to translate human-readable domain names (e.g. www.pelda.hu) to IP addresses (e.g. 192.168.1.1), thus enabling Internet users to easily navigate the web. However, BIND's role is much more complex and critical than that; ensures the smooth operation of the domain name system, which is essential for the stability and security of the Internet.

POSIX (Portable Operating System Interface) is a collection of standards created to promote compatibility between operating systems. POSIX standards are crucial in the world of software development, especially for those working with UNIX-based systems such as Linux. These standards ensure that different operating systems handle file systems, character devices, and other basic system-level functions in a similar way.
