  INTRODUCTION

Linux is a computer operating system which is based on free and open source

software which can be installed on a wide variety of computer hardware, ranging

from mobile phones, tablet computers, routers and desktopcomputers, mainframes and supercomputers. Linux is a leading server operating

system, and runs the 10 fastest supercomputers in the world. Linux is a

multitasking, multiuser operating system that is known for its stability. Although

modified by numerous people, its robustness stems from its Unix-like architecture

that keeps peripheral software components isolated from the core software (the

kernel).It is Licensed under the GNU General Public License (GPL).

Software support: After-sales service provided by a software publisher or vendor in

solving software conflicts and usability problems, and in supplying updates and

patches for bugs and security holes in the program. 

In response to customer demand and to the increasing maturity of the open source

software market, Software support companies are now offering Linux support and

open source software support in simpler, packaged, formats. Providers of opensource support delivered a fast one-stop shop solution. If a client needs an answer,

a new feature, or a fix, these software support companies can get it straight from

the author or they can simply provide it themselves, without time consuming

conditions, qualifications and referrals up the chain.

Types of Linux and Open Source Software Support

Our two broad categories of support are:

 

Helpdesk advice and diagnostic research  Direct intervention to diagnose and resolve problems.

1.  Helpdesk advice and diagnostic research:

This form of open source software support is designed primarily for those

who would expect their own technical staff to handle everyday problems, i.e.

it backs-up and extends in-house resources when they are approaching their

limits. Helpdesk support is normally staffed within office hours, but 24x7

supports can be arranged as appropriate.

2.  Direct intervention to diagnose and resolve problems:This form of open source support essentially involves company staff and

associates directly monitoring, configuring or managing your software

systems, rather than merely advising your own technical staff on the matter.

It is most commonly invoked to cover emergencies and one-off system

changes. Intervention support (onsite or remote) can be provided out of 

office hours and for a single consolidated annual fee, subject to negotiation.

As with helpdesk support, the single flat rate option is essentially for those

who prefer predictability over the fine-grained savings that come with

payment for exact work done.

Advantages of software support:

1. This helps the customers to solve their software related issues easily and

fastly.

2. Sometime these issues are solved without going anywhere.

3. It solves the issues accurately.

4. Also provide useful updates to our system.

5. Help in removing bugs and errors in the system.

My search on this topic is going on. Till now, I found about some software support

companies and their way of working. I will include more things and add it to my

term paper topic.
