Definition: EEPROM (pronounce as "E-E-PROM") stands for Electrically Erasable Programmable Read-Only Memory. It is a non-volatile ROM chip which used for storing a small amount of data in computers or some other electronic devices. Through EEPROM, an individual byte of data can erase and reprogrammed entirety, not selectively by the electrical voltage.

Definition: ECC Memory stands for Error-Correcting Code Memory is a type of RAM that adds error detection and correction circuitry to automatically detect and correct single-bit memory errors in any of the chip. As the name of the memory suggests, ECC memory is a kind of memory that can identify and fix the most common data error, but it used for single-bit memory errors.

Definition: EPROM (pronounced ee-prom ) stands for Erasable Programmable Read-Only Memory. EPROM is a type of ROM chip that can retain the data even if there is no power supply. The data can be erased and reprogrammed by using ultraviolet (UV) light. The UV light clears the data on the chip so that it can reprogram. For writing and erasing data on the EPROM, we need a particular device which is known as PROM programmer. The process of programming an EPROM is often called BURNING, and the box into which it is plugged to program it an EPROM burner.

Definition: VRAM (pronounced "vee ram") stands for video random access memory or video RAM. It is a particular type of memory used on some video adapters to speed up the display of images on the screen. VRAM costs more than regular RAM (DRAM, dynamic RAM), but it does make the screen snappier. VRAM is the random access memory which is used to store the image and video data which is being displayed by the computer, or you can say that it will serve as a buffer between the CPU (Central Processing Unit) and video card.

Definition: RAM Disk is also known as RAM Drive. A RAM disk is not a disk at all; It is a program which takes the portion of the system memory (RAM, in the form of memory chips) and uses it as a disk drive. You can create a larger RAM disk, if your computer has more RAM.

A RAM disk can also take the form of a hardware device or a virtual disk. RAM drive makes use of regular RAM instead of accessing the data bus. Sometimes RAM drive also makes use of the compressed file system, so that compressed data can access but without decompressing the compressed data.

Definition: A laser printer (also known as Page Printers as they prints the whole page at once) represent a real technological revolution. laser printer is a type of printer which makes use of a laser beam to produce an image on the drum or you can say that it is a printer that makes use of a focused beam of light to transfer text and images onto paper. It was first developed by Gary Starkweather at Xerox PARC in 1971. Laser printer makes use of laser technology for the printing of copies onto the paper.

The first relatively affordable laser printers were the Apple LaserWriter and the Hewlett-Packard LaserJet. Prices have dropped like a rock and quality is way up since those machines came out, but the underlying technology remains the same.

Definition: DRAM stands for Dynamic Random Access Memory. DRAM is a technical term for a type of random access memory (RAM) that can retain its contents only for a very brief period (measured in milliseconds) and must, therefore, be continually refreshed by reading its contents at short intervals.

Definition: Flash memory (Known as Flash Storage) is a type of non-volatile storage memory that can be written or programmed in units called “Sector” or a “Block.” Flash Memory is EEPROM (Electronically Erasable Programmable Read-Only Memory) means that it can retain its contents when the power supply removed, but whose contents can be quickly erased and rewritten at the byte level by applying a short pulse of higher voltage. This is called flash erasure, hence the name. Flash memory is currently both too expensive and too slow to serve as main memory.

Hard Disk Drive Definition: It is also called HDD,"disk drive," (hard drive) or harddisk is a non-volatile. The hard disk drive is the primary storage unit of the computer. This is where your data, programs and the Windows system that is used to make your computer are physically saved in a digital form (string composed of 0s and 1s). There harddisk capacity is expressed in gigabytes (GB). More hard disk drive will have a large capacity, the more you can install programs or store documents in your computer.

The operating system provides set functions to create, synchronize, control, execute the processes on the system. In the earlier time when the operating system was not available then every program required full hardware access or time for execution. To overcome this problem and used the CPU efficiently, the operating system introduced.
