The Basic Input Output system (BIOS) is a type of software that provides an interface between the hardware components of a computer and its operating system. It is usually stored in a Read Only Memory (ROM) chip. As it is stored in a ROM chip, its contents can never be erased and can be accessed …
Blu-ray is an optical storage format developed by Sony and Phillips. It was created to store large amounts of high definition video and sound. Blu-ray’s name came from the type of laser it uses to read and write data. The laser is a hue of blue-violet. A blue-violet laser has a shorter wavelength than the …
CPU is an acronym that stands for central processing unit. The central processing unit is responsible for performing all of the mathematical calculations that are required for a computer to function properly. Because a computer cannot function without the CPU (which may also be referred to as the central processor or just the processor), it …
CPUs process data using instructions stored in the computer memory or RAM. The RAM is a temporary storage area that makes information and instructions available to the microprocessor, which does not have to use this information until required. The two processor classifications are the Reduced Instruction Set Computer (RISC) and the Complex Instruction Set Computer …
A HBA (host bus adapter) is an integrated circuit adapter or circuit board that is designed to provide physical connectivity between a computer host and storage devices or a network. In addition to the physical connection, an HBA also provides input/output (I/O) processing and alleviates the host computer microprocessor from having to conduct data retrieval …
Many people install security features on their computer in order to prevent unauthorized users from accessing the computer when they are away. For example, login identification, file encryption, and even biometric identification are all sufficient methods of keeping intruders out of someone’s personal information. However, some users may wish to go even further by locking …
ECC (Error Correction Codes) is a method used to detect and correct errors introduced during data storage or transmission. Certain kinds of RAM chips inside a computer implement this technique to correct data errors and are known as ECC Memory. ECC Memory chips are predominantly used in servers rather than in client computers. Memory errors …
Firewire, also known as IEEE 1394 and i.Link, is a high speed serial bus developed by Texas Instruments and Apple computers in the mid 1990s. Firewire is compatible with more than 63 electronic and digital devices, which makes it a great choice for many people. Technically speaking, Firewire is a PC serial bus interface standard …
In the modern world of technology, almost any device can be tethered to another in order to increase performance and processing capabilities. An example of this is the ability to connect a computer to a television. This can be done in order to record television shows and movies or to control the television in question …
An Apple MacBook can last some time without the keyboard getting damaged. If the keyboard gets damaged (for e.g. a loose key falls out of the setting) or the user simply wants a new keyboard, he/she will need to replace the keyboard in question. The MacBook has a fairly simple case that users with the …
