Server Software: Operating Systems

The Microsoft Windows operating system dominates personal computers, but in the server world the most popular operating systems are FreeBSD, Sun Solaris, and GNU / Linux, which are derived from and similar to the UNIX operating system. UNIX was originally developed for microcomputers and servers, which gradually replaced microcomputers. UNIX was the logical and efficient choice as the server operating system. The site proxy-seller.com has a large number of proxy servers to work with.

Server-based operating systems have many common properties that make them more compatible with each other, for example: no graphical user interface (or only one version of the graphical interface); the ability to reconfigure the system (hardware and software) in some cases without shutting down the system; means for backing up important data at frequent and / or regular intervals; the ability to move data between different sections or devices in a “transparent” (invisible, without interference) way for the user; flexible and sophisticated networking capabilities; properties (daemons in UNIX or Windows services) that make program execution more efficient; waterproof security system, data and memory protection. In addition, these server operating systems in many cases interact with hardware sensors to detect certain conditions, such as overheating, microprocessor or hard drive failures, or other types of alerts, so that a human operator can take action to correct problems.

Because in some cases the requirements for servers are diametrically opposed to those of personal computers, it is very difficult to design an operating system that is equally suitable for both environments; operating systems can be adapted for personal computers, but are not ideal for servers, and vice versa.

Windows is less used on servers than the latest version of the popular Mac OS X (it is UNIX-based and gives its users full access to the UNIX operating system) in the family of personal computer operating systems and some native operating systems (for example, z / OS ); but most servers run operating systems, versions of UNIX or clones of it. Even if the popular GNU / Linux operating system, such as UNIX, is often used on servers, the system may be ideal for servers, but not satisfactory for personal computers.

The advent of microprocessor-based servers has spawned several versions of the UNIX operating system running on Intel x86 or AMD microprocessors, including Solaris, GNU / Linux, and FreeBSD. The Microsoft Windows family of operating systems also runs on Intel or AMD devices, and since the Windows NT operating system, certain features have been included to enable it to be used on servers.

While the operating systems for servers and personal computers remain different, the hardware performance and security improvements in both cases make the difference blurry. Only one main criterion separates them, manufacturers and distributors. Currently, some operating systems for personal computers or servers use the same source code and differ only in some configuration conditions.

Server applications

Server-side applications are specific and designed to perform only server-type operations, as are personal computer or mainframe applications that are designed specifically for these environments.

Most server applications stand out in that they are completely non-interactive; they do not display information on the screen and do not expect commands from the user. In fact, they work discreetly with the server and only work with workstations (clients) that are connected to the server. These types of applications are called daemons in UNIX terminology and services in Windows terminology.

Server applications typically start when the server starts up, continuing to run until the server is shut down. A server that only receives requests uses the same application types all the time and cannot confirm to the requesting computer that it was satisfied. Some server applications on some server systems only start when a request is received from a client, and then stop again after it is satisfied.

The main difference between personal computers and servers is not hardware, but software. Operating systems run on dedicated servers. They also run applications specially designed for the desired processes.
