Evaluate your communications

The communication that I use is different for the different uses i want to use it for, I use email to send important files to other email accounts such as sending teachers course work. I use SMS and voice communication on my mobile phone to contact people instantly and to socialize. I use IM to socialize with my friends for instantly replies and I also use it to send files such as photos ect.
I best communication that I use is voice communication because it gives an instant reply rather than having to wait for them to log onto their account to check there emails or check there mobile phone for a text.
