You can not use MS Access this way as Access does not support concurrency (multiple users updating information on the same table). For concurrency you need to upgrade to SQL Server

I mean if happens one after the other its ok.
DB Read should not fail.
Atleat the connection should be concurrent.

Well, if there's only one user accessing your program at a time (because msaccess cannot support multiple users at the same time).
Then there isn't any problem as long as you use the correct connection strings in your program.

read this: http://www.csharphelp.com/2006/01/ms-access-application-with-c/ to get you started.
Then you will understand what emoreau meant by checking the connection string.

Now to 2 person try access the db from 2 different machine. i will it throw exception. or 1 will wait for the other.

Oh, that depends if you are trying to write/update at the same time. If yes, then you will run into errors (throw exceptions). If you are just reading, then it'll be able to run fine if both users use read only access (specify this in the connection string)
