What is bluetooth?

Question

bluetooth used in computer terminology

Answer 1

Bluetooth is the equipment which is used by the cellphone which use to connect the cellphone with computer. It is acting like the wire which use to transform the messages from the other machine.

Answer 2

Bluetooth is a radio standard and communications protocol primarily designed for low power consumption, with a short range (a few metres to 100 metres depending on the power rating) based around low-cost transceiver microchips in each device.

Bluetooth lets these devices communicate with each other when they are in range. The devices use a radio communications system, so they do not have to be in line of sight of each other, and can even be in other rooms, so long as the received transmission is powerful enough.

Remember, Bluetooth is a protocol specification and the technology has been implemented in a variety of devices. So its not anything related to hardware or software as such, though hardware and software is needed for a Bluetooth implementation.

Answer 3

I'll try to explain Bluetooth in my own words. The standard mumbo-jumbo can be confusing for beginners...

Basically, Bluetooth is a SHORT-RANGE (< 30 feet) wireless communication protocol that allow devices to communicate. You may think of Bluetooth as an "invisible wire", in a certain way. For example, you may use Bluetooth to:

- Synchronize your PDA
- Connect to a headset (PC or cell phone)
- Print
- Exchange files between computers
- Connect a keyboard and mouse to your PC
- Etc.

Note that all of these could be done with a wire. However, Bluetooth allows you to do it wirelessly.

Bluetooth is in NO WAY replacement for WiFi or cellular signal. It is simply a way of securily removing wires... That how I see it.

Good luck!

Bluetooth is an industrial specification for wireless personal area networks (PANs), also known as IEEE 802.15.1. Bluetooth provides a way to connect and exchange information between devices such as personal digital assistants (PDAs), mobile phones, laptops, PCs, printers, digital cameras and video game consoles via a secure, globally unlicensed short-range radio frequency.

Answer 5

I'll resist quoting from wikipedia although you really should read the entry there.

Basically, we needed a system and set of rules that would allow electronic devices like a pda, a mobile phone and a portable computer to talk to each other at close range. Ideally, these devices would discover each other and provide easy transfer of files, printing, remote access connections and much more.

Unfortunately they fudged it a bit, it can be a bit confusing at times for the novice user and there are some security concerns. Overall, it is still a useful thing: for instance, I use it to sync my cell phone with my outlook contacts just by being in the vicinity of my computer. No strings attached. I guess it depends on your needs and how you use it.

Answer 7

Bluetooth is a technical industry standard that facilitates communication between wireless devices such as mobile phones, PDAs (personal digital assistants) and handheld computers, and wireless enabled laptop or desktop computers and peripherals. A single Bluetooth-enabled wireless device is capable of making phone calls, synchronizing data with desktop computers, sending and receiving faxes, and printing documents.

Bluetooth applications
Wireless control of and communication between a cell phone and a hands free headset or car kit. This is the most popular use.
Wireless networking between PCs in a confined space and where little bandwidth is required.
Wireless communications with PC input and output devices, the most common being the mouse, keyboard and printer.
Transfer of files between devices via OBEX.
Transfer of contact details, calendar appointments, and reminders between devices via OBEX.
Replacement of traditional wired serial communications in test equipment, GPS receivers and medical equipment.
For remote controls where infrared was traditionally used.
Sending small advertisements from Bluetooth enabled advertising hoardings to other, discoverable, Bluetooth devices.
Wireless control of a games console, Nintendo's Wii and Sony's PlayStation 3 will both use Bluetooth technology for their wireless controllers.
Sending commands and software to the LEGO Mindstorms NXT instead of infrared.

Bluetooth is in a variety of new products such as phones, printers, modems, and headsets, to name a few. Bluetooth is acceptable for situations when two or more devices are in close proximity with each other and don't require high bandwidth. Bluetooth is most commonly used with phones and handheld computing devices, either using a Bluetooth headset or transferring files from phones/PDAs to computers. Since Bluetooth uses short-range radio frequencies, it is not as effective for setting up networks that can be accessed from remote locations as with Wi-Fi.

Bluetooth also simplified the discovery and setup of services. Wi-Fi is more analogous to the traditional Ethernet network, and requires configuration to set up shared resources, transmit files, set up audio links (e.g. headsets and hands-free devices), whereas Bluetooth devices advertise all services they actually provide; this makes the utility of the service that much more accessible, without the need to worry about network addresses, permissions and all the other considerations that go with typical networks.

A Bluetooth device playing the role of the "master" can communicate with up to 7 devices playing the role of the "slave". This network of "group of up to 8 devices" (1 master + 7 slaves) is called a piconet. A piconet is an ad-hoc computer network of devices using Bluetooth technology protocols to allow one master device to interconnect with up to seven active slave devices (because a three-bit MAC address is used). Up to 255 further slave devices can be inactive, or parked, which the master device can bring into active status at any time.

At any given time, data can be transferred between the master and 1 slave; but the master switches rapidly from slave to slave in a round-robin fashion. (Simultaneous transmission from the master to multiple slaves is possible, but not used much in practice). Either device may switch the master/slave role at any time.

Bluetooth specification allows connecting 2 or more piconets together to form a scatternet, with some devices acting as a bridge by simultaneously playing the master role in one piconet and the slave role in another piconet. These devices have yet to come, though are supposed to appear in 2007.
