Client outdated means that the client (the software used to connect to the server) is out of date. You need to update your version of Minecraft.
It means that the server or the person connecting to the server do not have the same game version. If the server is v1.7.2 and the person connecting to the server only has v1.7.0 then they can't talk to each other. Or it can be the other way around. They both have to have the same version of the game.
Either you don't have the latest minecraft client or the person is using the program session stealer which when someone joins the server it kicks them with the message outdated cleint and takes their il logs onto a specified server your oped the does /op command to gain admin
You update your minecraft or get the older version. If your minecraft version doesn't match the server's version, then you can't join it no matter what you do.
No you don't you can download it on a outdated minecraft as long as the download you download is the same as the outdated minecraft you choose
