The System Management Bus (abbreviated to SMBus or SMB) is a single-ended simple two-wire bus for the purpose of lightweight communication. Most commonly it is found in chipsets of computer motherboards for communication with the power source for ON/OFF instructions. The exact functionality and hardware interfaces vary with vendors.
Power Management Bus. The Power Management Bus (PMBus) is a variant of the System Management Bus (SMBus) which is targeted at digital management of power supplies. Like SMBus, it is a relatively slow speed two wire communications protocol based on I²C. Unlike either of those standards, it defines a substantial number of domain-specific ...
Dell OptiPlex. OptiPlex (a portmanteau of "optimal" and "-plex") is a line of business-oriented desktop and all-in-one computers made for corporate enterprises, healthcare, the government, and education markets. Initially released in 1993 by Dell, these computers typically contain Intel CPUs, beginning with Celeron and Pentium and currently ...
In computer hardware a host controller, host adapter or host bus adapter ( HBA) connects a computer system bus which acts as the host system to other network and storage devices. [ 1] The terms are primarily used to refer to devices for connecting SCSI, SAS, NVMe, Fibre Channel and SATA devices. [ 2] Devices for connecting to FireWire, USB and ...
In computing, an input–output memory management unit ( IOMMU) is a memory management unit (MMU) connecting a direct-memory-access –capable (DMA-capable) I/O bus to the main memory. Like a traditional MMU, which translates CPU -visible virtual addresses to physical addresses, the IOMMU maps device-visible virtual addresses (also called ...
Bus (computing) In computer architecture, a bus[ 1] (historically also called data highway[ 2] or databus) is a communication system that transfers data between components inside a computer, or between computers. This expression covers all related hardware components (wire, optical fiber, etc.) and software, including communication protocols.
The Intel 8080 ( "eighty-eighty") is the second 8-bit microprocessor designed and manufactured by Intel. It first appeared in April 1974 and is an extended and enhanced variant of the earlier 8008 design, although without binary compatibility. [ 3 ] The initial specified clock rate or frequency limit was 2 MHz, with common instructions using 4 ...
System bus. A system bus is a single computer bus that connects the major components of a computer system, combining the functions of a data bus to carry information, an address bus to determine where it should be sent or read from, and a control bus to determine its operation. The technique was developed to reduce costs and improve modularity ...
