Description

If you run a business, it’s probably pretty apparent how important computer networking is. Put simply, networking impacts everything – from applications to backup and recovery tools, from the way your team communicates to the way important information is stored.

Well, can you imagine your day without sending a message to your friends? Can you spend your day without chilling with Netflix? Well, the answer is NO!

Well, have a look at these points!

  • About one billion computer systems are connected to the internet.

  • About 3.2 billion people use the internet from which 1.7 billion internet users are Asians.

  • The Internet consists of five billion computing devices such as computers, phones, modems, switches, routers etc.

  • According to Google, the Internet consists of 5 million Terabytes of data.

  • Approximately 204 million emails per minute are sent over the Internet.
