A token bus uses a shared bus for communication. Hosts on the bus are ordered in a logical ring, with access to the bus coordinated by passing a token (a special packet) around the ring, indicating permission to transmit. The intent is to get the robustness of a simple bus protocol with the deterministic response time of a token ring.
Unfortunately, because the bus is shared, each host on the bus must wait for the token to be completely transmitted before it can pass it on. This is in contrast to a token ring, where the token passes through each host with only a few bits delay. This gives the token bus considerably worse latency than a token ring.
The reliability of a token protocol over a (CSMA protocl such as Ethernet ) is undermined by the complex protocols needed to recover the token at exactly one host should it become corrupted.

What are address bus n data bus?
All computers use three types of basic buses. The name of the bus is generally determined by the type of signal it is carrying or the method of operation. We group the buses into three areas as you see them in their most common uses. They are as follows: Control (also called timing and control bus) bus, Address bus, and data (also called a memory bus) bus. Instruction (I), Operand (O), Input/Output Memory (I/O MEM) or Input/Output Controller (IOC), and Computer Interconnection System (CIS) Time multiplexed bus Control Bus The control bus is used by the CPU to direct and monitor the actions of the other functional areas of the computer. It is used to transmit a variety of individual signals (read, write, interrupt, acknowledge, and so forth) necessary to control and coordinate the operations of the computer. The individual signals transmitted over the control bus and their functions are covered in the appropriate functional area description. Address Bus The address bus consists of all the signals necessary to define any of the possible memory address locations within the computer, or for modular memories any of the possible memory address locations within a module. An address is defined as a label, symbol, or other set of characters used to designate a location or register where information is stored. Before data or instructions can be written into or read from memory by the CPU or I/O sections, an address must be transmitted to memory over the address bus. Data Bus The bidirectional data bus, sometimes called the memory bus, handles the transfer of all data and instructions between functional areas of the computer. The bidirectional data bus can only transmit in one direction at a time. The data bus is used to transfer instructions from memory to the CPU for execution. It carries data (operands) to and from the CPU and memory as required by instruction translation. The data bus is also used to transfer data between memory and the I/O section during input/output operations. The information on the data bus is either written into.

What are the 3 bus types present in every CPU?
The three types of bus present in every CPU are address bus, data bus and control bus.
What is bus interconnection?
Bus interconnection is important component of computer: architecture. It is a communication channel. It connects various components of computer to communicate with each other. The instruction (I) bus allows communication between the CPU and memory. It carries to the CPU the program instruction words to be operated on by the CPU from memory or returns instructions to memory. The I bus is controlled by the CPU. It is capable of sending or receiving data while the operand(O) bus is receiving or sending data at the same time, but only in one direction at a time. Operand (O) Bus The operand (O) bus allows communication between the CPU and memory or the CPU and an I/O Controller (IOC). The CPU controls the operation in both cases. The O bus is capable of sending or receiving data, while the I bus is receiving or sending data at the same time, but only in one direction at a time. The direction of the data depends on whether the CPU is reading data from memory or data is being written back into memory.

What are the conditions in parallel operation of generator?
the operation of connecting an alternator with other alternator or with common bus-bars is known as synchronizing.Generally alternator used in power system where they are connected in parallel with other alternator.condition for parallel operation of an alternator1. The terminal voltage of incoming alternator must be same as the bus-bars voltage.2. The speed of incoming alternator must be such that its frequency f =pn/120 as the same frequency of the bus-bars.3. The voltage of incoming alternator and the bus-bars voltage are in same phage.
What would you look for on an idler pully on an international school bus?
Damage, play/wobble, squealing while in operation.
Is a data bus unidirectional or bidirectional?
The control bus is a unidirectional bus because it can receive the data from any kind of inputs and send back the output. This whole process is done by the data buses.
