what is the difference between bluetooth, firewire and wi-fi?

Answer 1

Bluetooth is a wireless connection between two devices. The two devices are connected by a protocol equally set on each device (if the protocols are not identical there will be no communication) Most common devices are a monile phone to a computer or a printer to a computer. Bluetooth is a short range communication system. It is more severe on battery life in a mobile phone when connected to another device. Another use for bluetooth is for mobile phone use in a car in a hands free situation. The vehicle needs to be prepared for this and most have a microphone in the roof lining of the car above the drivers head. This does away with the bluetooth earpiece.
Firewire is a cable connecting to suitable devices such as a digital or video camera linked to a computer. This is a short range system but has a much faster data/photo transfer rate.
(in case you meant firewall it is an anti virus protection when a computer is connected to the internet)
Wi Fi is much like bluetooth. It has a wireless system with longer range of communication and allows larger data transfer. It is more advanced with newer technology than bluetooth.

A further system called zigbee is also available although its technology is even more recent. It allows other devices to wirelessly communicate with each other. These could be sensors or valves communicating with a central control unit. Zigbee has a faster data transfer rate is less hungry on power and is recognised as the way forward for the future.

Another wireless system is called X10 which is used for home entertainment such as a theatre where dimming of lights is automatic when a DVD is played

Answer 2

All of them are forms of connection between the computer and a peripheral (e.g. keyboard, camcorder, mouse, external hard drive). Let's start with firewire. Firewire uses a cable to connect the peripheral to the computer. For example, you recorded some video clips on your camcorder and want to save it on to your computer. This is a physical connection. Now as for the other two, they do not connect to the computer through a physical connection but rather connect through transmitting a signal. Bluetooth connects to your computer and vice-a-versa by transmitted an radio signal. It is like a walkie talkie between two people. For example, using a cordless mouse on a laptop. Bluetooth is only good for short distances, about 10+ meters (i.e. 30 feet). As for Wi Fi, like Bluetooth there is no physical connection but rather connects via radio signal. However, Wi Fi works for much longer distances (300 feet) than Bluetooth and transmits at a much greater rate. For example, using a desktop with Wireless connection to the Internet to download an entire movie.

Answer 3

Firewire is a cable to connect cameras and such to the PC and is very quick. Bluetooth connects one device to another but not in a network. Wi-Fi is a wireless network.

Answer 4

Bluetooth is a newer version of infrared, where you can send files to computers, PDA's, and newer cell phones. A firewire is a usb cord, but it sends info faster. Wi-Fi is pretty much a newer way to connect to the internet.

Answer 5

Bluetooth is a short range wireless protocol, firewire is a USB-like interface and WiFi is a wireless networking technology that is fast and has a much longer range than Bluetooth.

Answer 6

802.11 b, g, and (I believe) n are all interoperable - devices with any of these capabilities can talk to one another. However, communication will be limited to the rate of the slowest device involved in a transfer (eg g talking with b will operate at b speeds but g talking to g can still talk at g speeds even if a b device is in the network). 802.11 a operates at a different frequency so it cannot interoperate, however "dual-band" devices do exist have two radios - one for each radio band but they are not worth it unless you already have 802.11 a and must continue to support it. Also specified range for b, and g are 300ft - your results may vary. Bluetooth is not a networking technology, per se. It is intened as a low data rate peripheral connect - mice/keyboards, audio, etc. That being the case, it has much lower data rate and range (30ft) unsuitable for networking.

Answer 7

There are a ot of standard for communicating through wireless connection.

blue-tooth and IEEE-802.11 (Wi-fi & Wi-max) are the 2 that u asked.

Bluetooth is developed for the ad-hoc networks where as the IEEE 802.11 is developed for an infrastructure based network.

Both communicate on same freq 2.4 Ghz.


Fire wire (IEEE 1394) on the other hand is used for high speed wired communication.

Answer 8

Bluetooth is very low powered and only works over very short distances. You do not need a wire to use this. Tends to be rather slow.

Firewire is done through a cable and allows extremely fast transfer rates.

wifi again is wireless but alllows a much larger distance between the access point and the computer.

Answer 9

Firewire is a kind if connector, like usb. Bluetooth and wifi are wireless communications.

Answer 10

i know but im not going to tell u lol (sticks tongue out at u), no was that mean of me, im sorry i feel bad now, im going to cry now, just leave me alone, i cant stand all the qs arghhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh (runs out of room screaming, pulling out hair)
