Browser is what you use to brows (surf) the net. Microsoft(Windows) calls their new browser "Edge". It seems to work OK. It used to be called "Explorer" There is probably hundreds of different browsers if the truth be known. Remember AOL? "you've got mail" I think that was called Netscape. Browsers are different than email clients but just as many different kinds of email clients. I have Chrome, Firefox and Microsoft Edge browsers on my computer. I mostly use Chrome. Disregard all of this if you are too stubborn to learn. :)
