Internet communication

How do we communicate over the internet?


Email is split over two categories; POP3 and IMAP4.

With POP3, you retrieve Emails from the server and only the ones you download will be stored on your device. The advantage of this is that it doesn't use up your data allowance and doesn't fill up the storage if you are using a mobile phone.

With IMAP4, Emails are pushed onto your device. No matter how much your data allowance is, it will also fill up your storage. The advantage of this is that you can retrieve important Emails instantly.

Social Networking

Social Networking includes everything that involves socializing online. Instant Twitter and Facebook etc. are examples of Social Networking. Advantages are that you can talk to lots of people in one message.


VoIP stands for Voice over Internet Protocol. VoIP doesn't include video, it is just audio.

Skype and Facetime are examples of VoIP with video. If the video is turned off, this would be VoIP. An advantage of VoIP is that it is free (provided your internet connection is free), so you save on phone bills.

Instant Messaging

Instant messaging is a new technology that is like text messaging but it is in real time, an IM conversation is more like a real conversation but in text. The difference between IM and text messaging is that you tend to reply and read messages instantly whereas with text messaging, you tend to read a message and reply to it when you're not busy. Examples of IM are, KiK, MSN and BBM
