Write a 5 pages paper on unix overview. UNIX communication capabilities have also contributed in High-performance computing sector as a company named Computer Associated International implemented a powerful system “Advantage Gen (release 6.5)” on UNIX platform to speed up the development of J2EE applications and web services (Ohio Supercomputing Center to Deploy Hp Linux Supercomputer. 2002). UNIX back end server support the automatic generation of enterprise java beans facilitated the development teams to develop the J2EE application more efficiently. By the UNIX fast XML proxy support, web services are developed in no time on a distributed system as compared to the previous server architecture. IBM 32 way UNIX servers were also launched in the year 2001 with the code name “Regatta”. The microprocessor architecture comprises of 1 GHz 64 Bit Power 4. This UNIX server is capable of self-healing technology and decreasing system failures. The system is capable to divide into 16 virtual servers which enable the businesses to unite several machines into one (Popovich 2001).

The Client-server model of UNIX was the core component for the growth of the Internet and reshaping of the distributed systems networks. Interprocess communication in the UNIX operating system involves the connection between the system components logically and physically. It supports real-time network applications that allow the user to exchange messages in an interactive session. UNIX is known as a command-line interface due to the nonexistence of a GUI environment Today UNIX is equipped with a GUI along with dynamic communication functionalities. Some of the registered UNIX products are HP-UX, IBM AIX, SCO UnixWare, SGI IRIX, Sun Solaris, etc.

UNIX system administrator is responsible for installing software, patches, administer file systems, analyze and constantly monitor the performance. If any issue occurs, the system administrator troubleshoots the issue with the help of available tools and commands.
