There are not enough people who offer advice to help others learn about computer networks. For some reason, however, certain facts about networking tend to be misunderstood. This article describes the commonly held misconceptions that people have.
TRUE: Computer networks can be used without internet access
Some people assume networking makes sense only for those with an Internet connection. Although it is common for a home network to connect to Internet service, it is not necessary. Home networking supports file and printer sharing, streaming music or video, or even gaming between devices in the home, without access to the Internet.
FALSE: WiFi is the only kind of wireless networks
The terms "Wireless" and "Wi-Fi Network" are sometimes used interchangeably. All Wi - Fi networks are wireless, but wireless also includes types of networks built using other technologies such as Bluetooth. Wi- Fi is still the most popular choice for home networking, and for mobile phones and other mobile devices supporting Bluetooth, LTE or other.
TRUE: Individuals can be tracked on their IP addresses
Although persons device can theoretically be assigned to any public Internet Protocol (IP) address systems, the systems used to allocate IP addresses on the Internet link them to certain geographic locations to some extent. ISP customers in one city, for example, usually shared pool of addresses with consecutive numbers. Some technologies like anonymous proxy servers exist that are made for hiding a person's identity online by making sure their IP address is not tracked, but they have some limitations.
FALSE: Home Networks must have at least one router
Installing broadband router simplifies the process of setting up a home network. The devices are all connected to this central location via a wired and/or wireless connection, automatically creating a local network that allows file sharing between devices. Connecting a broadband modem into the router also provides automatic Internet Connection Sharing. All modern routers also includes built-in support network firewall automatically protects all the devices connected behind it. Finally, many routers include additional options for easy set up printer sharing, Voice over IP (VoIP) systems, and so on.
All of these functions can technically be achieved without a router. Two computers can be networked directly with each other as a peer - to - peer connection, or a computer can be designated as the home gateway and configured from the Internet. Although routers are obvious time savers and much easier to maintain, router-less setup can work especially for small and/or temporary network.
