Primary memory is also known as main memory or may also refer to "Internal memory." and primary storage. All those types of computer memories that are directly accessed by the processor using data bus are called primary memory. That allows a processor to access stores running programs and currently processed data that stored in a memory location.

Secondary memory is also known as secondary storage. The secondary memory is accessed indirectly via input/output operations. This memory is also called permanent, external, stable or persistent memory. It is characterised by its slowness and cheapness, relative to the RAM, and by its permanent appearance.

Memory is an essential component of the computer. It is a hardware device that assembled on the motherboard for storing data and instructions for performing a task on the system. Two types of memory are used by the computer, one for storing data permanently and second for operating.

Definition: SDRAM stands for Synchronous Dynamic Random Access Memory. SDRAM operates more efficiently as it works according to the synchronization of the clock. This makes it easy to manage faster, and the speed of the SDRAM measured in MHz instead of nanoseconds. SDRAM introduced in 1969-70. It most widely used in computers. Nowadays it is also used in other systems.

Definition: NVRAM stands for Non-Volatile Random Access Memory. It is a kind of RAM that can store the data even when there is no power. Ex:- Flash memory is a kind of NVRAM.

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.

In terms of computing’s history, we’re just beginning to scratch the surface of the lifestyle applications of touch-sensitive gadgets. In this article, we’ll take a look at two of the most important touch-based input technologies used in computers, smartphones, laptops, and tablets.

Whether you’re looking to replace a failed drive or upgrading to get more capacity and faster access times, installing a hard drive is simple. Just follow these steps to insert, secure, and power a new HDD in your desktop PC.

There are three types of storage that we can use for our files:HDDs, SSDs, and cloud-based storage.

In some cases, we have the option of foregoing one type in favor of another when looking for more capacity, faster load times, or dynamically shifting capacities. Read on to determine which applications are best suited to which storage types.

The principle form of electronic MEMORY used in computers prior to the invention of semiconductor memory chips. It consisted of thousands of tiny rings called cores, made from a magnetic FERRITE material and each threaded onto three fine copper wires: the whole formed a two-dimensional mesh much like a knitted textile.

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.

Understanding RAM on a PC gets pretty complicated, especially if you're using DOS instead of Windows. If your system is working okay already, don't bother with this information because it's pretty technical. But if you're running out of memory-if certain programs won't run or you can't create large files-you need some background knowledge before you march down and buy more memory. You may already have enough!

In humans, the memory is mind warehouse , where are stored for a later use the various components experience. The memory of a computer somewhat similar but more limited at its possibilities.

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.

Firmware is a category or class of memory chips which contain information that is permanent (meaning it isn't erased when you shut off your computer or when the power suddenly goes out on a dark and stormy night). The best examples of firmware are theROM chips in your computer that contain programs installed at the factory. Firmware cannot be altered, per se, but in some cases the whole chip can be completely replaced by a technician when it becomes outdated or obsolete.

Fatal error!? Why do they do this to us? Why can't they just say, "Oh, excuse me, but your system has a serious problem. The trouble may just be temporary, and if you'll turn off the computer and try again, maybe everything will work fine."
