Bluetooth is an example of personal area network. It is used for providing communication between peripheral devices like wireless mouse or keyboard with the computer.

It is used by modern healthcare devices to send signals to monitors. It is used by modern communicating devices like mobile phone, PDAs, palmtops etc to transfer data rapidly.

It is used for dial up networking. Thus allowing a notebook computer to call via a mobile phone. It is used for cordless telephoning to connect a handset and its local base station. It also allows hands-free voice comml1nication with headset.

It also enables a mobile computer to connect to a fixed LAN. It can also be used for file transfer operations from one mobile phone to another. Bluetoothusesomnidirectionalradio waves that can through wallsor othernon-metalbarriers. Bluetooth devices have a built-in short range radio transmitter.

The rate provided is 1Mbps and uses 2. Bluetooth Architecture Bluetooth architecture defines two types of networks: Salve-slave communication is not possible. These parked nodes are secondary or slave stations and cannot take part in communication until it is moved from parked state to active state.

This node is also called bridge slave. FSK with Gaussian bandwidth filtering. Both master and slave communicate in half duplex mode. The slave sends in the next odd-numbered slot if the packet in the previous slot was addressed to it.

It is used where fast delivery is preferred over accurate delivery. Bluetooth Frame Format The various fields of blue tooth frame format are: It is 72 bit field that contains synchronization bits. It identifies the master.

This is bit field. It contain 18 bit pattern that is repeated for 3 time. The header field contains following subfields: This 3 bit field can define upto seven slaves 1 to 7.

If the address is zero, it is used for broadcast communication from primary to all secondaries. This 4 bit field identifies the type of data coming from upper layers.

This flow bit is used for flow control. When set to 1, it means the device is unable to receive more frames. This bit is used for acknowledgement.

This bit contains a sequence number of the frame to detect retransmission. As stop and wait protocol is used, one bit is sufficient. This 8 bit field contains checksum to detect errors in header.

This field can be 0 to bits long. Dinesh authors the hugely popular Computer Notes blog.

Write short note on evolution of computer generations. Computer architecture, like other architecture, is the art of determining the needs of the user of a structure and then designing to meet those needs as effectively as possible within economic and technological constraints.

• “Computer Architecture is the science and art of selecting and interconnecting hardware components to create computers that meet functional, performance and cost. The write transaction is similar except that the processor is the data source and the WRITE signal is the one that is asserted.

Different bus architectures synchronize bus operations with respect to the Computer Architecture: A Quantitative Approach, Morgan Kaufman Publishers, San Francisco, California. [Chapter 6 of this book discusses. Thus allowing a notebook computer to call via a mobile phone.
