2005 The motherboard is the main circuit board of a microcomputer. The motherboard contains the connectors for attaching additional boards. Typically‚ the motherboard contains the CPU‚ BIOS‚ memory‚ mass storage interfaces‚ serial and parallel ports‚ expansion slots‚ and all the controllers required to control standard peripheral devices‚ such as the display screen‚ keyboard‚ and disk drive. Collectively‚ all these chips that reside on the motherboard are known as the motherboard ’s chipset. On

The impact of the losses in the system is quite extensive. It is stated that 15% of the board are typically rejected during an early processing inspection along with an additional 5% rejected during the final testing. This results in a production order increase of 25%. 5.What recommendations would you make for a short-term solution to CBF’s

MOTHERBOARD [pic] A motherboard is the central printed circuit board (PCB) in computers that holds many of the crucial components of the system‚while providing connectors for other peripherals. The motherboard is sometimes alternatively known as the mainboard‚ system board‚ or‚ on Apple computers‚ the logic board. History of Motherboards [pic] Before generation of Microprocessors i.e. in 1st‚ 2nd and 3rd generation computers‚ the computer was usually

In a sense computers have been around for centuries. The abacus‚ a counting machine‚ was invented by the Chinese sometime between 500 and 400 BC. The numeral zero was first recognized and written by Hindu’s in 650 AD‚ without which written calculations would be impossible. In 1623 the great grandfather of the processor was born‚ the calculating clock. Wilhelm Schickard of Germany invented this adding‚ subtracting‚ multiplying‚ and dividing machine based on the principle of algorithms. For the next

CET 2123: Microcomputers and Basic Digital Communications 4/25/11 Anthony DeCamillo Serial VS Parallel The two most basic types of communication are serial and parallel. They are so common that even the cabling bears the name serial cable and parallel cable. Since electricity behaves according to the laws of physics‚ it is impossible to get the electrical signal to go any faster. There are two ways to get the data from one place to the other faster. The first is to squish the data bits tighter
