HLD means High level Design where we will concentrate on
designing the main modules of the application.LLD means Low
Level Design where we will concentrate designing the
componenets in the modules.The Best example for this is in
the application the Module designing like how many fields
it should contain,how many links and archetececture of
module will come under HLD.In the low level logics of the

Answer / mouna
HLD is also called as architectural design. it shows the
flow of project.
LLD is also called detail design.
A project may have 1 hld and any number of lld's that means
the hld gives the whole architecture.
where as lld gives the details of each module(a project may
have many modules but single architecture)

Answer / castor_troy
HLD is high level design. It gives only the layout of the
modules of the complete application and how it is expected
by the customers. Does not normally have enuf details for a
developers to start with the development. Prepared by the TM
or the Manager.
Where as LLD is Low level design. It gives the complete and
detailed requirement of all the modules etc. normally
prepared by project manager or the project lead.
A tester mainly works with the LLD.
