Data Storage Devices

Caching

Punch cards store data. That data can then be analysed by feeding the cards into a punch card reader.

CdRom - To read cd's CDR - To read and write CD's DVDrom - to read dvd's DVDR - To read and write dvd's Zip- Used like a floppy, but will store 100 Mb of storage Floppy - stores 1.44 Mb of data Hard Drive- where everything is saved There are tons more types of drives.. do a search on google for it

Storage devices are like a memory stick, iPod, floppy disk, etc. Basically anything that you can take with you and put in your pocket is a storage device. Memory is data that is stored into the computer that can be put on to a storage device.

Storage devices: Hard drives, CD, DVD, BluRay disc, floppy disc, flash drive.

Used to store data.

Memory: RAM

Used to store data which is only recognized by the computer. If current is terminated data is lost from the memory.

At the Google Web site, click Images at the top menu, and search on "random access memory".

why are there interblock gaps on tapes

Normally Volatile memory or storage is the real memory in the computer. It is volatile because if the power fails or is turned off the memory (RAM) is erased or reset.

Absolutely NO,

Hard disk is made up of a ferromagnetic material such that data is stored in the hard disk by magnetization.the hard disk has a read/write head such that it magnetizes and demagnetizes the platter and also detects the amount of magnetization.

but flash memories use transistors to store data in it.when a 5V current is passed in a transistor it is similar like holding a 1 bit data.thus flash memories has transistors which hold data by passing current.

since transistors occupies a large space the working of thousands of transistors are simplified in to single chip known as IC.tis technology is known as VLSI.thus flash memories has a IC which stores data in arrays..

An application called a disk defragmenter is the tool used to achieve this. However one could also specifically match the disk segment layout with the disk rotation speed as one sets up the disk or even build a RAID array to increase access speed.

That depends a lot on how much you pay per KB or MB.600 KB is about 0.6 MB; check how much you pay per MB.

I depends on your operating system.

In DOS you would use fdisk to create the partition on your removable disk and the format command to actually perform the format.

I just got this exact same question for homework in my CS course today, what a surprise. A floppy disk, magnetic coated and rotates.

Go to my computer. Check your drive there. If it says DVD-ROM then u can play both DVD and CD or if it say CD-ROM then it only plays CD.

No.

for temperary solution ,, click on folders in my computer window,, and left side u click on d drive it will open,,, after that chek any .exe, .ini, .dll file is directly copied on d drive, if copied remove the files,,, and if opssible move ur data into some other drive and format d drive,,, then defenetly opens for temperary solution ,, click on folders in my computer window,, and left side u click on d drive it will open,,, after that chek any .exe, .ini, .dll file is directly copied on d drive, if copied remove the files,,, and if opssible move ur data into some other drive and format d drive,,, then defenetly opens Aravind

Download flash disinfector from the link. Only 129 Kb. Run the exe. Really you will have the best solution,

thanks bye

Do u like buttsecks or 69?

Modern RAM (Random Access Memory) is a high speed semiconductor storage media that only retains information as long as power going through it. In any device that has no form of hard memory (ie. Solidstate or Disk drives), it will not keep information. As soon as the computer is turned off all the information on the RAM will be lost and you wont be able to get it back. There is some RAM that will keep information, however the amount kept is simply enough for your computer to know where the chips on the motherboard are and computer statistics.

The result would be a computer with no operating system. With no operating system you could not load a web browser or do anything on your computer except play with the boring menus you see when you start up the computer.

ROM storage is CDs (those you buy with music), DVDs (movies) and etc. ROM mean "read only memory", that is cannot be changed.

True

I believe they will thanks to the last developments in the artificial intelligence,but i think it could be dangerous for humans,because if computers turn against us we won't have a chance to defeat them.

Scientists predict that computers will process massive amounts of information in the future and surpass the human thinking abilities by the year 2050.

"Flash drives" use a technology that has a large but limited number of erase/write operations before it starts to fail. The memory in flash drives is commonly engineered with multi-level cell (MLC) based memory that is good for around 3,000-5,000 program-erase cycles, but some flash drives have single-level cell (SLC) based memory that is good for around 100,000 writes. RAM writes and erases hundreds or thousands of times a second in certain areas. You do not want the RAM in your computer to fail that quickly.

DVD as an industry standard was announced in November 1995 and backed by major players in the CE, IT and movie industry. The first players appeared in Japan in November, 1996, followed by U.S. players in March, 1997. To produce DVD players, one needs to license a range of patents, owned by different companies. A number of these companies (Philips, Sony, Matsushita and Toshiba) have decided to license the necessary patents through one licensing agent. Philips has been selected to take up this administrative role. Matshusita, was the company mainly responsible for the development of DVD as it is today. Philips, one of the first companies to make CD players, was the first to make a DVD player. The invention of DVD cannot be attributed to one person or one company.

If you know that you computer has a CD-ROM drive navigate to My Computer and look for an image (icon) of a CD or the name CD-ROM drive. That is likely to be the CD-ROM drive, although it may have additonal capabilities such as DVD ROM, DVD-RW etc.

In a computer using Windows the CD-Rom drive is usually given the drive letter 'D'.

If the images/icons names are no help right click the icons one by one and check the resulting menu. You're looking for the icon with the menu optiomn eject. That will be the CD-ROM drive.

If you are looking to buy one make sure you specifically ask for a CD-ROM drive, usless you need additonal capabilities as above, and specify whether you need it internal or external to the computer.

no, the head not touching the surface of the hard disk. If it touch the great chance of data may be lost. only the head of floppy disk is touch the surface of the disk.
