Connectivity

WAYS OF CONNECTING:

•Networking

•Wireless fidelity

•Wired connections

•Servers

•Syncing devices

•The Cloud/ Air drop

•Bluetooth

•Media cards

WHY CONNECT?

•Sharing information

•Sharing printers

•Sharing a security system

•Sharing software

•Uploading/downloading from the internet

•Syncing information between devices

•Proximity marketing

WIRED Vs WIRELESS

•Wired connections are faster than

Wi-Fi

•Wired connections are more reliable than Wi-Fi because no signal

is lost along the way

•Wired networks allow for safer data transfer than Wi-Fi

•Wi-Fi is easy for lots of people to

use simultaneously

•Wi-Fi is available without the limitations of wire lengths in a

certain area. This zone referred to as a WLAN (Wireless Local Area Network)

•Wi-Fi can be used on a range of

devices

•Long lengths of wire used for wired

connections can be expensive

•Bluetooth is wireless, allowing for the transfer of information

within a short range (10m), but wireless fidelity is often better as it has a

greater range

ADVANTAGE OF USING BLUETOOTH:

Bluetooth is wireless technology so information can be transferred

wirelessly between devices within a 10m range of each other. It is also used in

cars to connect them to phones, so that people can have hands-free telephone

calls while driving, preventing many road accidents. Many smartphones have

Bluetooth capabilities.

WHY IS A WIRELESS NETWORK SOMETIMES CHEAPER

THAN A WIRED ONE?

It is cheaper to install a router that all the devices used can

connect to, than long lengths of expensive wires connecting devices.

Installation costs are higher for wired networks.

WHAT DOES EACH DEVICE NEED FOR IT TO WORK

WITH WIFI?

Each device

needs a wireless adapter to allow it to connect to the internet, unless it has

built-in Wi-Fi capabilities. A wireless Ethernet bridge can be used to add

wireless capabilities to a device. An internet connection is needed from an

internet service provider (ISP).

GIVE ONE LIMITATION OF USING BLUETOOTH

Bluetooth

has a very short range compared with Wi-Fi of 10m, which allows for data

transfer between devices in close proximity only.

WHAT ADVANTAGE DOES A WIRED NETWORK HAVE OVER

A WIRELESS ONE?

Wired networks are usually more reliable and faster than wireless

networks because none of the signal is lost while it travels through the wires.

Wired networks can also be safer and more stable.
