Data Storage Devices

The Universal Disk Format (UDF) is a standardised file system for optical discs. The UDF standard was adopted by the DVD Consortium as a standard format for DVDs. Although a standard there are variations which means that not all discs can be read by all suitable machines.

The role of a disk drive is to store (write) and retrieve (read) digital information for a computer system.

Storage may be either on magnetic disks (Hard Disk Drive - HDD), in semiconductors (Solid State Drives - SSD), or it may use a combination of magnetic disks and semiconductors (Hybrid Hard Disk Drive - HHDD).

In all cases, data is retained even when power is removed (non-volatile).

Disk drives are located in the Secondary Tier of storage, that is they are not directly accessible to the computer (Primary Tier) but are accessed through an interface such as SCSI, ATA, or USB

In computing, an optical disc drive (ODD) is a disk drive that uses laser light or electromagnetic waves within or near the visible light spectrum as part of the process of reading or writing data to or from optical discs. The first digitally recorded optical disc was a 5-inch audio compact disc (CD) in a read-only format created by Philips and Sony in 1975.

If you are asking how data was first stored for computers to be retrieved later it was on punch cards. Holes would be placed in the cards representing 0's and 1's. Thousands of cards would be fed in which in turn would turn into a program. If any card was fed out o order they would need to start all over again.

As far as I'm aware USB drives don't go up to 500GB; the closest you'll be able to get is to buy an external HDD, which will normally cost around £ 30-50 depending on make.

SDRAM and DDR RAM are memory integrated circuits used in computers. The difference between the two is the speed because SDRAM is a single data rate which is slower than DDR RAM that stands for the double data rate. Which means the chip reads or writes two words of data per clock cycle.

Pen drive is an Removable Device. It is use to File sharing. Easy to Read and Write files. Pen Drive is not consider as an Input/Output Device.

It's use to erase and clean all files on the disk removing viruses and unnecessary files. Use also to install new Operating system to the disk if disk in particular is use on a computer system.

Hard drive, external hard drive, floppy disk, memory stick, CD-ROM and Recordable DVD are all storage devices.

You can use a number of different things to store files. Here are some of the basics:

* External Hard Drive (connects via USB/Firewire) * USB Flash Drive

* Any type of multimedia card (SD, XD, Compact Flash) I'm sure there are others, but this list exceeds the two that you asked for, so I'll stop there.

The storage device that stores the least amount of information is a floppy disk which only has a average storage space of 1mb

RAM is a primary storage medium, but it is volatile. Cache memories storage frequently accessible data.

Memory refers to random access memory (RAM) and storage refers to your hard disk space. Hard disk is what you save all you files and operating systems on and ram remembers where to find recently used items in order to bring them back fast. It's like if you think of your house as your storage. All the stuff you own is in your home but stuff you used recently you remember exactly wear it is, like maybe you wallet or keys, and that would be your memory

it is an input device

reprogrammable memory

Nowhere... is still there. Just that if you save new information it will write it over the deleted information .

memory in system is not in the form of energy .so it will have memory in ones and zeros.(binary)

Hard disk drive inside the PC, CD or DVD drives/disks, USB (thumb drive, jump drive), and floppy disk drive/disk storage.

Other storage can be external Hard disk drives, tape drives, RAID drives and the newer Blu-Ray.

Yes a scanner is a processing device.

Currently, inside a regular desktop PC the largest unit of size would be 1 TB (1000 GB), and with this unit it becomes very difficult to completely fill the storage device.

However, potentially, the largest is the yobibyte, which is a whopping 10,000,000,000,000,000,000 bits of data. Basically, if scaled down into human language it would be the information capacity of the observational universe, meaning every bit of known knowledge ever recorded, translated into every language and coppied 10,000,000 times over.

They could be the RAM modules or Random Access Memory modules. They are solid state memory devices which are volatile in nature. This means that their memory gets deleted or reset when the system is turned off or shut down.

Other boards are in the expansion slots. Mostly PCI. Where you can add video capture, extra USB's or Extra sound cards etc.

There are also slots for improving the graphics, by plugging in a graphics card, with it's own memeory and processor, it improves on the default graphics of the motherboard and allows fast graphics for games and video processing.

ram stands for random access memory while rom is read only memory
RAM is Random Access Memory that is used to store data that is from using desktop applications or web browser based functions. ROM is Read Only Memory, ROM is used for only one thing and that is to read the memory that is integrated within the CD that you put in the computer. You can remember what ROM does by just remembering Read Only Memory, because all it does is what the name implies, which is to read data.

A hard disk drive consists of one or more thin disks that spin at high speed (1200 to 15000 rpm) while magnetic heads read data from them, hovering extremely close to them without making contact.

There are multiple devices, infact. Fans probably dont count as "devices", but those can be attached to motherboards. Then there's the GPU (Graphics Processing Unit a.k.a the Graphics Card) and the CPU (Central Processing Unit a.k.a the Processor). More can be attached but you can look those up on google.
