EEPROM stands for Electrically Erasable Programmable Read-Only Memory. An EEPROM is like an EPROM chip since it can be written in or programmed more than once. Unlike the EPROM chip, however, an EEPROM chip need not be taken out of the computer or electronic device of which it is part when a new program or …
When a document or other item is printed to a file instead of a local or networked printer, it allows the file to be saved in a format that can be used by a different printer. Information such as page and line breaks, font spacing, and other layout information is saved when printing a document …
Mirroring is the automated process of writing data to two drives simultaneously. Mirroring is used to provide redundancy, backup, multiple concurrent accesses and uninterrupted accessibility. If one drive fails, the redundant drive will continue to store the data and provide access to it. The failed drive can then be replaced and the drive set can …
It is a well-known fact that most computers are susceptible to hard drive crashes or virus attacks. Backing up information is a practical and necessary precaution to protect one's data from being lost forever. There are several realistic methods for backing up data. The best backup method for your data depends opon many factors, including: …
A key concept in data storage is that it is linear, logical, and systematic in nature. When someone ‘saves’ data to the hard disk, the disk will follow a logical system. A hard disk can be compared to a large, square piece of graphing paper composed of squares, a thousand long and a thousand wide. …
We all use electronic devices, whether they are mobile phones, computer routers, MP3 players, cable boxes, etc. These electronic devices include hardware, the physical electronic components and software, programs that help these components run effectively. Firmware is a mix of both. Firmware Firmware is usually defined as a type of program that runs within an …
PROM stands for Programmable Read-Only Memory. It was invented by Wen Tsing Chow in 1956. Unlike a ROM chip, a PROM chip comes from the manufacturers devoid of any programming. Programming is done by the end user or the makers of electronic devices which require a permanent data storage device. Since it is cheaper than …
A voice changer is exactly what the name states; it changes the sound of your voice. In addition, many voice changers can go further than just changing the sound of your voice, many voice changers can change the gender of a voice (for instance, from female to male) and enhance the voice in many different …
Using dual monitors refers to using two physical display devices to increase the viewing space running on a single computer. Microsoft Windows Operating Systems and Mac OS X now support dual and multiple monitor configurations. Setting up dual monitors is easy. However, it requires the user to add a second video card or install a …
An IBM ThinkPad laptop can have three hardware password sets: Power-On Password Hard Disk Password Supervisor Password Power-On Password RT/CMOS RAM has 8 bytes reserved for the power-on password and the check character. The 8 bytes are initialized to hex 00. The microprocessor can access these bytes only during POST. After POST is completed, if …
