What Is the Difference Between Internet Modem Router Ranges N, G, B, A?

Networking through traditional Ethernet cables is reliable and effective, but long runs of networking cable aren’t a practical way for most consumers to access the Internet or share printers. By the late 1990s wireless networking using a Wi-Fi standard began to make networked computing easy and accessible for everyone. Routers using several versions of the 802.11 wireless standard are available, with differing speeds and ranges. Understanding the differences can be important when you’re in the market for a new router.

RFID Technology Disadvantages & Alternatives

Radio frequency identification systems tag items with small antennas and electronics, allowing nearby readers to track their movements via radio waves. These RFID systems are especially useful for quick identification of the contents of a shipping pallet, inventory on a shelf in a warehouse, and for secure checkout. While the technology has many benefits, industry groups and suppliers of competing technologies have highlighted some disadvantages, and are working to develop alternatives that address these issues. Other technologies are often better suited for specific applications.
