One of the daily needs people have nowadays is to communicate. Whether people change information because they want to or they have to, they communicate. This is why the communication systems were invented. People invented these in order to achieve:

• Quality – people need less periods of time to communicate much
• Reliability – people need to communicate all time
• Security – people need to make sure they don't get misunderstood by other people,
• Versatile and flexible – people need to use communications systems in order to do more than originally intended.
• Friends.

Because people want to communicate over long distances, they invented tele-communications systems – like Internet and telecom solutions.

Once people got friends and / or business partners they started to

• send different data to each other – we named this Data Communication
• talk to each other and we named this Voice Communication
• try to use telecom systems to do new things - then they need someone to make this possible – we named this Professional Services.
