A SD card, or Secure Digital card, is a memory card used in portable devices for non-volatile memory storage. The cards are commonly used in tablet computers, cell phones, digital cameras, and GPS devices. The SD standard was first introduced in 1999 as an improvement over MultiMediaCards. The standard for SD cards is maintained by …
Dielectric grease is a translucent substance used to seal electrical conductors in order to prevent dirt, dust, sand, and other foreign materials from sticking to the conductor and preventing it from transferring a current between the two contact points. Dielectric grease also blocks moisture, thereby preventing corrosion. How Dielectric Grease Works Dielectric grease is a …
Optical mice are the de facto standard for mice to communicate between the end user and the computer. The optical mouse is a great improvement of the mechanical mouse that was created in the early 1970s. Agilent Technologies introduced the Optical mouse in 1999.

NVRAM is an acronym for Non-Volatile Random Access Memory. NVRAM is a type of Random Access Memory (RAM) that retains its information when power is turned off. The NVRAM is a small 24 pin DIP (Dual Inline Package) integrated circuit chip and is thus able to obtain the power needed to keep it running from …
EPROM or Erasable Programmable Read Only Memory was invented by Engr. Dov Frohman. It is a ROM-type chip that can hold data from 10-20 years. It is different from PROM because it can be programmed more than once. An EPROM programming is erased only through exposure to ultra violet light. The EPROM is configured or …
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 …
In order to understand what a checksum error is, it is important to first learn what a checksum is. A checksum is a redundancy check during a computer’s start up process, which makes sure that the computer’s data is intact and unhampered. The data is scanned and tested for accuracy, either based on how well …
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 …
