While the terms CPU and microprocessor are often used interchangeably, a microprocessor is essentially an all-in-one CPU on a single chip. This single-chip design reduces the number of vulnerable electrical connections, improving reliability by reducing potential points of failure. As such, microproc...

Microcontroller units (MCUs)andmicroprocessor units (MPUs)are two kinds of integrated circuits that, while similar in certain ways, are very different in many others. Replacing antiquated multi-componentcentral processing units (CPUs)with separate logic units, these single-chip processors are both extr...
At the heart of a microcomputer lies the microprocessor. It carries out the arithmetic, logical, and control functions. The microprocessor communicates with all other elements of the system via a system bus. The memory stores data and instructions, whileinput devices, like a keyboard or a mouse...
As shown in the figure Dallas micro-controller 80c320 has 4 ports i.e. Port 0, Port 1, Port 2 and Port 3. Port 0: Port 0 is an 8-bit open drain bi-directional port. Port 0 is also the multiplexed low-order address and data bus during accesses to external memory. ...
What is a host bus adapter (HBA)? A host bus adapter (HBA) is acircuitboard or integrated circuit adapter that connects a host system, such as aserver, to astorageornetworkdevice. An HBA also provides input/output (I/O) processing to reduce the load on the host's microprocessor when ...
Based on the Intel 8008, it was the first nonkit computer based on a microprocessor. In 1974, the Intel 8008-based MCM/70 microcomputer was released by Micro Computer Machines Inc., later known as MCM Computers. Though released after the Micral and MCM/70, the Altair 8800 is often ...
In contrast to a computer microprocessor, a microcontroller is intended for some specific tasks. So the hardware requirements like RAM, ROM and other peripherals are very less. Thus everything is embedded into a single chip, by reducing the overall size very much. Low Cost Microcontrollers are...
