USB (Universal Serial Bus) is a hardware specification that allows a connection to be established between a source device and a peripheral device. Most modern electronic devices include at least one built-in USB port and can use USB technology to connect to other devices, such as keyboards, mice, cameras, flash drives, external hard drives, printers, media players, wireless network adapters, game consoles, and cell phones. USB technology allows devices to share data and is widely used to transfer files to an external storage device. Additionally, USB technology can supply power Read More

LBA (Logical Block Addressing)

LBA is Logical Block Addressing. Early PC hard drives were supported by the PC BIOS using Cylinder/Head/Sector addressing. To read or write from a specific sector on the disk, you specified the sector in terms of its cylinder number, its head number, and its sector number. LBA adressing uses just one number. In LBA addressing, the first sector on the disk is sector zero and all sectors on the disk are simply incremented from there.

DMA (Direct Memory Access)

Last edited by . Total of 1 comment in the discussion.

DMA stands for Direct Memory Access, a capability in modern computers that allows peripheral devices to send data to the motherboard’s memory without intervention from the CPU. The DMA controllers are special hardware – now embedded into the chip in modern integrated processors – that manage the data transfers and arbitrate access to the system bus. The controllers are programmed with source and destination pointers (where to read/write the data), counters to track the number of transferred bytes, and settings, which includes I/O and memory types, interrupts and states for Read More

What is a Microchip?

Last edited by . Total of 1 comment in the discussion.

A microchip, commonly called the integrated circuit, is a tiny electronic circuit. It is made up primarily of semiconductor devices. For the most part, these small microchips are used in nearly every type of electronic device known to man. As the years have gone on from their creation in the late 50s and early 60s, the microchip has become much smaller and more inexpensive to make. Because of this, it has allowed more users to gain access to greater types of electronics. The History of the Microchip In 1968, Jack Read More

Fingerprint Scanners

Last edited by . Total of no comments in the discussion.

Fingerprint scanners are biometric security systems designed to use the distinct features of an individual's fingerprints to provide security. Fingerprint scanners are now being used in police stations, security-intensive industries and, most recently, on computer shops as a peripheral device for computers. Biology of a Fingerprint Every person has marks on his fingers. These marks on the fingers are mainly for gripping things as they provide frictional resistance. These marks have a pattern and this pattern is called the fingerprint. The person's fingerprint is determined by his or her genetic Read More

The motherboard is the most essential component in a personal computer. It is the piece of hardware that contains the computer’s micro-processing chip and everything attached to it is vital to making the computer run. The term “mainboard” is also sometimes used to refer to the motherboard . Motherboard Components The motherboard is the flat, rectangular piece of circuit board inside the computer’s case to which everything seems to connect to for one reason or another. It contains the following key components: A microprocessor “socket” that defines what kind of Read More
