Domain
A domain, in the context of networking, refers to any group of users, workstations, devices, printers, computers and database servers that share different types of data via network resources. There are also many types of subdomains.
A domain has a domain controller that governs all basic domain functions and manages network security. Thus, a domain is used to manage all user functions, including username/password and shared system resource authentication and access. A domain is also used to assign specific resource privileges, such as user accounts.
In a simple network domain, many computers and/or workgroups are directly connected. A domain is comprised of combined systems, servers and workgroups. Multiple server types may exist in one domain - such as Web, database and print - and depend on network requirements. In computer science, the domain is the field whose needs the dedicated software satisfies and the industrial area that uses software as a secondary tool. These domains include medicine, auto-driving, commerce, education, engineering, mathematics, and others. Domain identification is an essential aspect of software architecture design, and this step settles how extensive, reusable. Consequently, the expensive, said the product would be and which tools (languages, frameworks, third-party services) will be used to implement, test, and deploy such software [1, 191-203].
In any domain that requires quick response time and low latency, the common languages are C and C++. They are used for cryptocurrency mining, low-latency networking, entertainment (particularly gaming) and modern space missions. C, aside from that, is anywhere the embedded devices (machines that do not run OSes) are in use: culinary, radio broadcasting, etc. Mission-critical software requires total stability and reliability where Ada and Assembly were used: military and early space missions. Most modern systems that require a higher degree of portability utilize Java: banking, enterprise software also falls in this category. Different fields that neglect performance can be accomplished with Python: data science, scientific computing, routine automation. [2, 6] Finally, anything that requires networking and can afford memory expenses or requires a browser runs on JavaScript or equivalent transpiled to it language: social media websites, weather forecast distribution, news agency, etc. Internet of Things is a particular example that mixes multiple needs and delegates to Java, C and Python.
