Raspberry Pi, a popular modern-class microcomputer. A microcomputer is a small, relatively inexpensive computer having a central processing unit (CPU) made out of a microprocessor. [2] The computer also includes memory and input/output (I/O) circuitry together mounted on a printed circuit board (PCB). [3]
one card (shown right) with the I/O part of the computer: a LED seven segment display, a 25-key keypad (hex+function keys), and a cassette CUTS interface (the circuitry to the left of the keypad) the second card (the computer board - see below), which included the CPU, RAM/ROM memory, and support chips
The family of microcontrollers are 16-bit, however, they do have some 32-bit operations. The processors operate at 16, 20, 25, and 50 MHz , and are separated into 3 smaller families. The HSI (high speed input) / HSO (high speed output) family operates at 16 and 20 MHz, and the EPA (event processor array) family operates at all of the frequencies .
The crucial function of a file server is storage. File servers are commonly found in schools and offices, where users use a local area network to connect their client computers and use Network-attached storage (NAS) systems to provide data access. A web server is a server that can satisfy client requests on the World Wide Web.
The microcomputer is sold as assembling kit, [8] that includes: A PCB. 7400 series TTL chips. A swappable EPROM chip and a socket (for firmware updates). A 32 KB CMOS SRAM (upgradable to a 64 KB chip) Game controller and VGA ports. USB port and cable for power. A game controller similar to the NES one. A keyboard controller with built-in non ...

Among numerous applications, this chip would eventually find its way into over one billion PC keyboards. At that time Intel's President, Luke J. Valenter, stated that the microcontroller was one of the most successful products in the company's history, and he expanded the microcontroller division's budget by over 25%.
