What is the maximum capacity of a DVD-RW?
A DVD-RW can typically hold 4.7 gigabytes of data. A smaller version of a DVD-RW with an 8-centimeter diameter has a capacity of 1.46 gigabytes.
Cloud storage capacity is the amount of storage you can avail on cloud.There are three main cloud storage models:
Public cloud storage services, such as Amazon's Simple Storage Service (S3), provide a multi-tenant storage environment that's most suitable for unstructured data.
Private cloud storage services provide a dedicated environment protected behind an organization's firewall. Private clouds are appropriate for users who need customization and more control over their data.
Hybrid cloud storage is a combination of the other two models that includes at least one private cloud and one public cloud infrastructure. An organization might, for example, store actively used and structured data in a private cloud and unstructured and archival data in a public cloud.
Cloud storage has become very common these days. Most of us rely on it to store our files, photos, music, etc. What exactly does it mean? How does it work? Why should I care?
Cloud storage refers to storing data online instead of locally on your computer or phone. This allows you to access your information from anywhere at anytime.
You probably already use cloud storage without even realizing it. For example, Google Drive, Dropbox, iCloud, OneDrive, Box, Amazon S3, Microsoft Skydrive, and other similar services allow you to upload, download, share, edit, and delete documents, photos, and other media files.
Cloud storage is becoming increasingly popular among consumers and businesses alike. With so much information being stored online these days, it makes sense to store some of your files in the cloud. Here are 5 reasons why you should consider storing your documents, photos, music, videos, etc., in the cloud.
Accessibility - With cloud storage, all of your files are accessible from anywhere you go. Whether you're at home, on vacation, or traveling abroad, you'll still be able to access your files.
Security - You won't have to worry about losing your files when you lose your device. Cloud storage providers make sure that your files are safe and secure, so you don't have to worry about hackers stealing your personal information.
Backups - Your files are backed up automatically, so you don't need to worry about losing anything. When something goes wrong with your computer, you can simply log back into your account and download everything again.
Sharing - You can share your files easily with others. Just upload your files to the cloud, and anyone else with the link will be able to view them.
Storage Space - Most cloud storage providers give you plenty of space to store whatever you like. There's no limit to how much you can save.
Reduce the mega-pixels (mp) - the size of the pictures. Unless you are planning to crop most of your picture, any thing bigger than 3 mega pixels is bigger than the screen of your computer. The smaller the picture you shoot, the more pictures you get. Click on! eD
How can you put music on an sd card?
Stick the SD card into a card reader attached to your computer (a USB device will be recognizable under Windows XP or above and after a minute or so you should be able to browse the card with Windows Explorer- it take a short time for the card to be registered on your machine) Copy the music files from their location and paste them into the SD card
Can you use DVD-r to burn movies?
Yes, but it depends on what DVD disc your DVD burner supports. Take an example, I could burn my movies and videos to DVD-r, DVD+r, DVD-rw, DVD+rw because my DVD burner supports those discs.
And please note that you need not only a DVD-r, but a DVD burner software to do the burning job.
The hard drive is the main memory where most documents and multimedia files are stored, for example music, images and video's. Not only are these files stored on the Hard Drive but also the Operating System is kept on the Hard Drive. A computer can have more than one Hard Drive and these can either be Internal or External. Disk drives (HDD) come in many different sizes in memory; ranging from Kilo-Bite as the smallest and Terabyte as the largest.
The implication of computer to the society?
The computer has influenced the society in both constructive and deconstructive ways. For example, while it has allowed much faster transmission of information, it has caused the erosion of human culture.
How should data be pronounced?
data has two ways of being pronounced.
Day-tu ("uhh.." like um... but very short)
or
Da (ah! like a short scream)-tu ("uhh.." like um... but very short)

_______________________________________________________________
I pronounce the word as "Day-tuh". Many people pronounce it "dah-ta", but I, along with many scientists, prefer "Day-tuh". If I were you I would pronounce it "Day-tuh". (second opinion)

What is the difference between magnetic media and optical media?
Optical media is written and read on disks with lasers, such as a CD-Roms, BluRays, and DVDs. Magnetic media is written and read with magnets (like your hard drive and a floppy disks (which are almost non-existant anymore)).
What are the basic operational concepts of computer?
hardware,software and 3rd is data. explain in detail then this question will be completed.
How do you remove Write Protection from a disc?
it depends on what type of disk if it is a 3.5 inch floppy then there is a tab on the corners that can be moved up or down. if you can see through it , it is write protected if not it can be used.
Name three examples of secondary storage devices?
The most popular secondary storage devices are hard disks, CDs, DVDs, USB Flash drive and floppy disks.
Why would a flash disk generally not be an ideal storage device for storing your movie collection?
It does not have enough storage capacity
A byte is a sequence of 8 bits (enough to represent one alphanumeric character) processed as a single unit of information. A single letter or character would use one byte of memory (8 bits), two characters would use two bytes (16 bits).
Put another way, a bit is either an 'on' or an 'off' which is processed by a computer processor, we represent 'on' as '1' and 'off' as '0'. 8 bits are known as a byte, and it is bytes which are used to pass our information in it's basic form - characters.
An alphanumeric character (e.g. a letter or number such as 'A', 'B' or '7') is stored as 1 byte. For example, to store the letter 'R' uses 1 byte, which is stored by the computer as 8 bits, '01010010'.
A document containing 100 characters would use 100 bytes (800 bits) - assuming the file didn't have any overhead (additional data about the file which forms part of the file). Note, many non-alphanumeric characters such as symbols and foreign language characters use multiple bytes.
A kilobyte (KB) is 1024 bytes, a megabyte (MB) is 1024 kilobytes and so on as these tables demonstrate.
1024 Bytes = 1 Kilobyte, 1024 Kilobytes = 1 Megabyte, 1024 Megabytes = 1 Gigabyte, 1024 Gigabytes = 1 Terabyte, 1024 Terabytes = 1 Petabyte, 1024 Petabytes = 1 Exabyte, 1024 Exabytes = 1 Zettabyte, 1024 Zettabytes = 1 Yottabyte
The yottabyte (derived from the SI prefix yotta-) is a unit of information or computer storage equal to one septillion (one long scale quadrillion or 1024) bytes (one quadrillion gigabytes). The unit symbol for the yottabyte is YB.
As of 2012, no storage system or network has achieved even one thousandth of a yottabyte (a zettabyte) of information. The combined space of all computer hard drives in the world was estimated at approximately 160 exabytes in 2006, and as of 2009, the Internet was estimated to contain close to 500 exabytes.
When used with byte multiples, the SI prefix indicates a power of 1000: 1000000000000000000000000bytes = 10008 or 1024 bytes
The term "yobibyte" (YiB), using a binary prefix, is used for the corresponding power of 1024.
Basic steps used by the processor in instruction processing are?
1.Fetch the most instructions from memory.
2.Read an apparend if required by the instruction.(Apparend is a quantity to be operated as directed by its associated instruction.)
3.Execute the instruction.(Do what the instruction says.)
4.Write the result backe into memory.(If required by instruction.)
Why do animations demand so much storage space and how can you overcome this?
Animations can take up larger amounts of storage space due to the requirement of number of "frames per second" or FPS. For film your are looking at 24 or more frames per second to maintain the illusion of movement, or persistence of vision. Depending on format you could go as high as 60 frames per second. So initially each frame, however large they are is effectively going to be repeated with variations at least 24 times a second. To reduce storage compression such as the MPEG standard can at regular intervals find Key Frames and between each key frame only store the delta, or difference, from the most recent key frame. Depending on scene the compression can be substantial. Along with image compression (per frame, rather then just the delta technique) can drastically reduce the storage requirement. Normally though, the film, animation, scene is first rendered raw, without any compression (hence massive storage) then ran through compression at a later time rather then at run time. This is done to allow fine tuning of the master and have variable options for the output. e.g. The Master File(s) can be compressed in serveral different formats for NTSC, PAL, DVD, Blueray, IMAX, Online, etc. Keeping the Master file uncompressed allows it to be compressed later on for different requirements.
