InfoPath and client machine plugin needes to use a InfoPAth form

[GAC.Me.Up.baby]

hello,

i just start using infoPAth and i have a question regarding it. Once i
develop an info Path form and deploy it on my sharepoint server with the WWF
workflow i will build for it. Those the user that will use my infoPath form,
need to have infoPath installed on their machine ? Do they basically need any
client component on their machine to use my form ?

sorry for that noob question,i just start with it.
