After understand on how to implementing unix part 1, currently we are look into detail on

X terminals
If you are running UNIX on a central high-spec computer and connecting to it from a group of less powerful terminals – as is the case with mainframe systems – you can install the X Window System on the terminals. This allows the terminals to access the central computer and run applications on it. It provides terminal users with a graphical interface they can use to interact with these applications.

Because X terminals do not need to run any applications apart from the basic UNIX operating system, the X Window System and basic utilities, they don’t need to have large amounts of memory and hard disk space. Therefore they’re a good way of reusing obsolete PCs. For example, a computer with a 486 processor, 16 MB of memory, and 200 MB of disk space would be an adequate X terminal. (more…)

After get to know on how to choose Unix part 1 and part 2, now time to implement unix.

Uses of UNIX

You can use the UNIX operating system on a wide range of computers, from standalone home PCs to high-end network and Internet servers. Because networking has been an integral aspect of UNIX throughout its development, UNIX is well suited to network environments. It is in wide use on academic and institutional networks as well as in the
corporate world.

UNIX servers are often used to provide infrastructure and services on networks and the Internet. For example, they can provide services such as the domain name system (DNS) and Dynamic Host Configuration Protocol (DHCP). They can be used as routers, file servers, and File Transfer Protocol (FTP) servers.

The Internet is a particularly common area of application for UNIX computers. The majority of the world’s web servers run on some variant of UNIX, including those that power Yahoo’s search engine and Apache’s official web site. (more…)

Last month, I have come across how to choose Unix, with which UNIX to choose, commercial UNIX, and open source UNIX, lets see how the “Brands of commercial UNIX“and “Brands of open source UNIX”.

Brands of commercial UNIX
Some of the most famous and widely used brands of UNIX include Sun’s Solaris and Hewlett Packard’s HP-UX.

Solaris is a binary-compatible operating system, which means that Sun have gone to some lengths to ensure that one version of their UNIX will run on all of their hardware. Solaris also features integrated Java support, although Java can be downloaded for any UNIX
distribution.

Sun also manufacture UNIX for Intel hardware as well as their own proprietary hardware. (more…)

While the Linux variant of UNIX is fast becoming a desktop operating system, UNIX’s multiuser capabilities make it ideally suitable in a server role.

When tasked as a web or database server, a properly configured UNIX system will provide unparalleled periods of uptime, requiring little service. The structure of UNIX means that in the case of a hardware failure, sections of a data structure can be taken offline, replaced and put online again without shutting down the system. This makes UNIX a good choice for mission critical applications.

UNIX’s multi-user capabilities make it highly resistant to attack. It’s designed in such a way that even if a malicious party did gain access to the system, their activities would be restricted to the user account they had access to, leaving them unable to damage critical system resources. (more…)
