A server is a device that occupies a higher position in the hierarchy of a computer network in terms of functionality. Through a server, computers can exchange data with each other, or they can access data stored on the server. Since a server is usually a key element of the function of a larger network, more powerful and higher-quality hardware is used for it, which makes its existence more secure than in the case of ordinary workstations.

A dynamic website, also known as a CMS portal or content management system, is especially suitable for users who need to change the content of the website frequently. The main advantage of a dynamic website is that it can be updated by the client, without the intervention of an external company.

A single-board computer (SBC) is a complete computer built on a single printed circuit board with a microprocessor, memory, and other components needed for a functional mini-computer. Single-board computers are commonly manufactured as demonstration or development systems for educational systems or for use as embedded computer controllers.

A microcontroller (MCU) is a small computer on a single integrated circuit chip. It contains one or more processor cores along with memory and programmable input/output peripherals. Program memory in the form of ferroelectric RAM is also often included on the chip, as is a small amount of RAM. Microcontrollers are designed for embedded applications used in personal computers, or other general-purpose applications consisting of various discrete chips.
