ABSTRACTTools links is an application which provides services to both technical and
nontechnical people.
This provides an interface to access almost all kinds of calculators and
converters.
This also provides some basic information about almost every topic of
science and technology.
The main purpose of this application is to provide the tools like calculators
and convertors at a single place.
Tools links is also called as “Tech Helper”.

INTRODUCTION
Tools links is a web application which has almost all the
technical information, formulae.
It also provides converters ,calculators and information about
them at a place.
Users should be able to use these conversion tools with ease.
By using this application users can get useful information
before performing their required conversions and calculations.

OBJECTIVE
Earlier, the calculations are to be made manually and
there’s no single platform where one can find all the
required information about any topic of science and
technology.
Various tools were available but not at single place.
Accessing the tools was also a difficult job for non-
technical people.

PURPOSE
This web application is very much useful to the students
as well as nontechnical people.
By using this application users can perform conversions
and calculations very easily.
Operations are performed by just entering the value.
It also provide basic information about those tools and
technologies.

EXISTING SYSTEM & DISADVANTAGES Existing system was the manual system.
In this manual system user must perform operations by remembering corresponding
formulae.
This doesn’t provide any information about the tools which is desired by user.
There is a problem for users to perform operations by their own.
DISADVANTAGES: No reliability.
Problems with remembering formulae.
High error rate.
User should perform whole work.
Difficult to compute.

PROPOSED SYSTEM & ADVANTAGES In proposed system, all the operation which are desired by the user are
performed by the system itself.
The user just need to enter the values on which he/she wants to perform the
calculations.
The system takes the value as input and perform required calculation.
The result is displayed instantly on screen.
ADVANTAGES: High reliability.
High accuracy.
Less effort.
Less time to compute.

MODULES In proposed system we have two modules:
1. Admin
2.User
ADMIN FUNCTIONALITIES:
Admin controls the whole system.
He maintains all the information about the technologies and conversion
tools.
He can add users to access this application.
He can insert, modify and delete new tools as well as description about
new technologies.
![Page 10: VIGNAN'S NIRULA INSTITUTE OF TECHNOLOGY & SCIENCE FOR WOMEN](https://reader036.fdocuments.net/reader036/viewer/2022062811/56815f12550346895dcdd528/html5/thumbnails/10.jpg)

User Functionalities
After registering of user he can access the system.
He can perform calculations which he wants.
He can also know about new technologies.
He can compute all operations accurately with in a less
time.

CONCLUSION
Tech helper is a core component built to help the users to
make all kinds of scientific calculations and conversions.
Users can also get some basic information about some
prominent topics of science and technology.
Moreover, this application was developed in such a way
that any further modifications needed can be easily done
like when there’s any technology upgrade.

FUTURE ENHANCEMENTS
In future we are planning to
Provide Software as downloadable file on user’s request.
Add some sample programs wherever required and an
interface to execute the sample programs which helps the
user to have a more clear understanding of it.
