by Jeff Tyson. System RAM. System RAM speed is controlled by bus width and bus speed. Bus width refers to the number of bits that can be sent to the CPU simultaneously, and bus speed refers to the number of times a group of bits can be sent each second. A bus cycle occurs every time data travels from memory to the CPU.
How is the speed of RAM measured?
Memory RAM Speed - Access Time, Megahertz (MHz), Bytes Per Second. Prior to SDRAM, speed was expressed in terms of nanoseconds (ns). This measured the amount of time it takes the module to deliver a data request. Therefore, the lower the nanosecond speed, the faster.
Bus speed usually refers to the speed of the front side bus (FSB), which connects the CPU to the northbridge. FSB speeds can range from 66 MHz to over 800 MHz. Since the CPU reaches the memory controller though the northbridge, FSB speed can dramatically affect a computer's performance.
Computers have two major types of buses: 1. System bus:- This is the bus that connects the CPU to main memory on the motherboard. The system bus is also called the front-side bus, memory bus, local bus, or host bus.
The memory bus is a type of computer bus, usually in the form of a set of wires or conductors which connects electrical components and allow transfers of data and addresses from the main memory to the central processing unit (CPU) or a memory controller.
A front-side bus (FSB) was a computer communication interface (bus) often used in Intel-chip-based computers during the 1990s and 2000s. The competing EV6 bus served the same function for AMD CPUs. Both typically carry data between the central processing unit (CPU) and a memory controller hub, known as the northbridge.
The input/output bus or io bus is the pathway used for input and output devices to communicate with the computer processor.
In computing, a peripheral bus is a computer bus designed to support computer peripherals like printers and hard drives.
A control bus is a computer bus that is used by the CPU to communicate with devices that are contained within the computer. This occurs through physical connections such as cables or printed circuits.
Processor bus is defined as the bus that provides the path for communication between the main buses send the central processing unit. It also serves as the communication medium between the central processing units and other chipboard devices in the CPU.
The internal bus, also known as internal data bus, memory bus, system bus or Front-Side-Bus, connects all the internal components of a computer, such as CPU and memory, to the motherboard. Internal data buses are also referred to as a local bus, because they are intended to connect to local devices.
Memory Transfer. The address register (AR) is used to select a memory address, and the data register (DR) is used to send and receive data. Both these registers are connected to the internal bus. DR is a bridge between the internal BUS and the memory data BUS.
Memory bandwidth is the rate at which data can be read from or stored into a semiconductor memory by a processor. Memory bandwidth is usually expressed in units of bytes/second, though this can vary for systems with natural data sizes that are not a multiple of the commonly used 8-bit bytes.
The External Bus Interface, usually shortened to EBI, is a computer bus for interfacing small peripheral devices like flash memory with the processor. It is used to expand the internal bus of the processor to enable connection with external memories or other peripherals.
In electrical power distribution, a busbar (also spelled bus bar, or sometimes as buss bar or bussbar, with the term bus being a contraction of the Latin omnibus, "for all") is a strip or bar of copper, brass or aluminium that conducts electricity within a switchboard, distribution board, substation, battery bank, or
An expansion bus is a computer bus which moves information between the internal hardware of a computer system (including the CPU and RAM) and peripheral devices. It is a collection of wires and protocols that allows for the expansion of a computer.
The real power and voltage are specified for buses that are generators. These buses have a constant power generation, controlled through a prime mover, and a constant bus voltage. Slack bus – to balance the active and reactive power in the system. It is also known as the Reference Bus or the Swing Bus.
Alternatively referred to as a line topology, a bus topology is a network setup in which each computer and network device are connected to a single cable or backbone. The following sections contain both the advantages and disadvantages of using a bus topology with your devices.
An address bus is a computer bus architecture. It is used to transfer data between devices. The devices are identified by the hardware address of the physical memory (the physical address). The address is stored in the form of binary numbers to enable the data bus to access memory storage.
1) On computer and telecommunication devices, a port (noun) is generally a specific place for being physically connected to some other device, usually with a socket and plug of some kind. Typically, a personal computer is provided with one or more serial ports and usually one parallel port.
In telecommunication and data transmission, serial communication is the process of sending data one bit at a time, sequentially, over a communication channel or computer bus.
System Bus Types and Functions. The CPU moves data around the computer on pathways that interconnect it to all the other components on the motherboard. These pathways are called 'buses'. The internal bus carries data within the motherboard.
