Wired to Wireless - the final answer
One of the most common questions we as consultants have to
answer on a daily basis is the difference between wired and
wireless networks. Let me summarize:
Wired: In simple terms; the communication between two devices
via cables. Wireless: the communication between two devices
without cables.
Now, is it that simple? Not exactly, each method of networking
has its own pros and cons.
Wireless networks do not use any form of cable. The transmission
of data (your files, music, printing to the printer etc) occurs
over radio waves... just like cordless phones or the Bluetooth
headset that came with that snazzy phone you purchased recently.
The major advantage of having a wireless device is the mobility
and freedom that comes with it. Moreover, there is less clutter
and fewer wires to worry about. But, you sacrifice in most cases
on speed and security.
Wired networks on the other hand have been around for some time
now. Officially known today as the Ethernet, the cables usually
connect these devices using CAT5 cables. The speed and security
in this scenario are greatly enhanced. The latest Ethernet
routers can support up to 1000Mb/s or a gigabit/sec. that's 10
times faster than the widely used 100 Mb/s router. Moreover the
over all cost of a wired network is lower, provides high
performance and better security than wireless networks.
The choice depends on your day to day activities. Wireless
networks won't become mainstream anytime soon in office
environments. But as home users, wireless networks have become
the choice. A little sacrifice in speed or security as a
residential user is minimal but for an enterprise environment -
well, it becomes a whole new ball game... and, pretty detailed
too.
