Google Talk and Google Chat are two services that help Google to be aggressive in the telecommunications business. Google Talk is an direct messaging client that you can install on your computer or smartphones, and it permits you to chat with online friends and even call them through VoIP. On the other hand, Google Talk is separate software, and you need to download and establish it on your computer prior to starting to use it.
However, with Google Chat, if you have an updated browser and internet connection, you can utilize it after logging in to your Gmail accounts. Google Chat is especially helpful if you do not want to chat with someone, but you cannot install applications on your current computer.
Google Talk does a lot more than Google Chat. The best feature of Google Chat is VoIP, a protocol that allows the transmission of voice in a packet-based network like the Internet. Another feature is video calls, which is a video chat program. However, it has been said that Google Chat and Google Talk are just two ways of retrieving the same service.
