C ontrol Bus: The control bus carries the control signals that make sure everything is flowing smoothly from place to place. E xpansion Bus: If your computer has expansion slots, there’s an expansion bus. Messages and information pass between your computer and the add-in boards you plug in over the expansion bus. In computer architecture, a bus (related to the Latin ’omnibus’, meaning ’for all’) is a communication system that transfers data between components inside a computer, or between computers.
In computing, a bus is defined as a set of physical connections (for example, cables, printed circuits, etc.) that can be shared by multiple hardware components in order to communicate with one another. The purpose of buses is <boldWto reduce the number of pathways needed for communication</bold> between the components, by carrying out all communications over a single data channel. This is why the metaphor of a data highway is sometimes used.
Posted filed under CompTIA A+, MICROSOFT MTA O/S. Alternatively referred to as a bus slot or expansion port, an expansion slot is connection or port located inside a computer on the motherboard or riser board that allows a computer hardware expansion card to be connected. The bus architecture belongs to a slotted-ring class. 32-bits of data, l4-bits address, and signalling buses span across a maximum of sixteen processors configured in a ring. The Computer Bus is a communication link used in a computer system to send the data, addresses, control signals and power to various components in a computer system. The computer buses are used to connect the various hardware components that are part of the computer system. In simple words, the computer buses are electrical wires which.Characteristics
If only two hardware components communicate over the line, it is called a hardware port, (such as a port or parallel port).
There are different types of computer buses. A bus is characterized by the amount of information that can be transmitted at once. This amount, expressed in bits, corresponds to the number of physical lines over which data is sent simultaneously. A 32-wire ribbon cable can transmit 32 bits in parallel. The term width is used to refer to the number of bits that a bus can transmit at once.
Additionally, the bus speed is defined by its frequency (expressed in Hertz), the number of data packets sent or received per second. Each time that data is sent or received is called a cycle.
It is possible to find the maximum transfer speed of the bus, or the amount of data that it can transport per unit of time, by multiplying its width by its frequency. For example, a bus with a width of 16 bits and a frequency of 133 MHz has a transfer speed equal to: ArchitectureBus Slots In Computer Games
In reality, each bus is generally constituted of 50 to 100 distinct physical lines, divided into three subassemblies:
*The address bus: sometimes called the memory bus, it transports memory addresses that the processor wants to access in order to read or write data. It is a unidirectional bus.
*The data bus: it transfers instructions coming from or going to the processor. It is a bidirectional bus.
*The control bus, or the command bus: it transports orders and synchronization signals coming from the control unit and traveling to all other hardware components. It is a bidirectional bus, as it also transmits response signals from the hardware.The Primary Buses
There are generally two buses within a computer.
*The internal bus: sometimes called the front-side bus, or FSB for short, it allows the processor to communicate with the system’s central memory (the RAM).
*The expansion bus: sometimes called the input/output bus, it allows various motherboard components (namely, USB, serial, and [contents/415-serial-port-and-parallel-port parallel ports], cards inserted in PCI connectors, hard drives, CD-ROM and CD-RW drives, etc.) to communicate with one another. However, it is mainly used to add new devices using what it’s called expansion slots connected to the input/output bus.Motherboard ChipsetComputer Slot Games For Sale
What is “chipset”? A chipset is the component that routes data between the computer’s buses, so that all the components that make up the computer can communicate with each other. The chipset originally was made up of a large number of electronic chips, hence the name.
It generally has two components. The first is the NorthBridge (also called the memory controller) that is in charge of controlling transfers between the processor and the RAM; this is the reason why it is located physically near the processor. It is sometimes called the GMCH, for Graphic and Memory Controller Hub.
The second is the SouthBridge (also called the input/output controller or expansion controller) that handles communications between peripheral devices. It is also called the ICH (I/O Controller Hub). The term bridge is generally used to designate a component that connects two buses:Bus Slots In Computer Game
It is noteworthy that, in order to communicate, two buses must have the same width. This explains why RAM modules sometimes have to be installed in pairs (for example, early Pentium chips, whose processor buses were 64-bit, required two memory modules each 32 bits wide).
