Magical Elf - FreeBSD Operating System

FreeBSD is a Unix-like system running on the x86 platform. It is marked by a mythical elf. It was developed from the BSD Unix system and was written by Berkeley, Calif. The first version was officially launched in 1993. BSD Unix and Unix System V are the two mainstreams of the Unix operating system. Later Unix systems are derivatives of these two systems.

FreeBSD is actually an authentic Unix system, but for legal reasons, it cannot use the "Unix" word as a trademark. It is also a free operating system that users can get from the internet.

Advantages of FreeBSD

1, Unix compatibility

FreeBSD is not free, FreeBSD is a toy for individual users. Since FreeBSD is a branch of Unix, it has Unix features that can do what Unix can do. Because professional Unix workstations are very expensive, FreeBSD can take advantage of the cheapness of PC hardware and software and take advantage of it to some extent to replace Unix systems. Many Unix applications can also run normally on FreeBSD.

2, extremely stable and reliable

FreeBSD is a true 32-bit operating system, the system core does not contain any 16-bit code, which makes it the most stable and reliable in the personal computer operating system. system. The FreeBSD workstation can continue to work for several years without any problems. It is therefore called "Rock-stable Performance", which means "rock-solid".

3, powerful network functions

FreeBSD is not only used as a personal workstation, but also used by some ISP (Internet Service Provider) as a network server to provide a network for users. service. For example, Yahoo's main servers are all using FreeBSD, and domestic NetEase is also widely used by FreeBSD. On the one hand, it is cheap because of FreeBSD, and more importantly because it has strong network functions and good stability necessary for network work. FreeBSD also supports the largest anonymous Ftp server on the Internet: Ftp.cdrom.com. The predecessor of the Internet, APA, is implemented using BSD Unix, so FreeBSD is very mature in terms of network.

4, multi-user, multi-task

This is a modern operating system. FreeBSD has dynamic priority preemptive multitasking capabilities that can be controlled and adjusted. This enables normal switching of multiple tasks even when the system is busy, and does not affect the operation of other programs when individual tasks are not corresponding or crashed.

Insufficient FreeBSD

FreeBSD is mainly for the Internet, as a server system, so it has a long way to go with ordinary users. It lacks the support of commercial databases and application software vendors, which is why it has entered many PCs.

A typical computer user can ignore FreeBSD as an operating system, because although it can run many programs, most of them are programs under Unix, and cannot run under Windows programs.
