A gigabyte is equal to exactly 1024 Megabytes. So basically a Harddrive is the part of a computer where the data is stored (for example: Music, Photos, Videos, etc.) With 15 Gigabytes of disk space you can store about maybe 5 movies or 20 videos or 2,200 text files on your computer and keep them saved. So if you need to store more than that if you are using a mac and have FileVault on you can turn it off and have a lot more Harddrive space by going to: Apple >System Preferences >Security >FileVault >Turn Off FileVault...

Are they still making HD DVD?
HD DVD (short for High-Definition/Density DVD) is a discontinued high-density optical disc format for storing data and high-definition video.[1] Supported principally by Toshiba, HD DVD was envisioned to be the successor to the standard DVD format. However, in February 2008, after a protracted high definition optical disc format war with rival Blu-ray, Toshiba abandoned the format, announcing it would no longer develop or manufacture HD DVD players or drives.[1] However, the HD DVD physical disk specifications (but not the codecs) are still in use as the basis for the CBHD (China Blue High-Definition Disc) formerly called CH-DVD. The HD DVD Promotion Group was dissolved on March 28, 2008.[2]Because all variants except 3× DVD and HD REC employed a blue laser with a shorter wavelength, HD DVD could store about 3⅕ times as much data per layer as its predecessor (maximum capacity: 15 GB per layer instead of 4.7 GB per layer).FROM::: http://en.wikipedia.org/wiki/HD_DVD
How many gb can a DVD hold?
A single DVD is capable of holding 4813 megabytes of data. Blu Ray disks, on the other hand, can hold 25600mb.
List the different data types and give an example where each would be used?
b, bytes: The smallest data type, isn't used very much when you're talking about files but it's the ground. kb, kilobytes: In one kb there's 1000 bytes. A document is often some kbs. mb, megabytes: In one mb there's 1000 kilobytes. This one is more used than the previous. A song is usually 3-6 megabytes big. A movie in dvd-quality is around 700mb big. gb, gigabytes: In one gb there's 1000 mb. This is also used more. A movie in HD is usually 4 gb, a bluray is 8 gb or more. Todays harddrives holds 250-1500 gigabytes, where 500-750 is most common. tb, terabyte: In one tb there's 1000gb. This isn't so common, but harddrives in different kinds usually holds around 1tb.
Can CSGO Run On My Macbook Air Early 2014 Specs 1.4 GHz Intel Core i5 -4 GB 1600 MHz DDR3 -Intel HD Graphics 5000 1536 MB?
Possibly. You need at least a 2.0 GHz processor but on a Mac it needs less processor speed than on a Windows PC. You have enough Ram and a good enough Graphics Card but the processor may let you down.
What is the difference between a DVD and CD?
AnswerData on a CD is written is form of small dots. A laser is used in CD drive to read data from CD. The light reflected because of the dots on the CD is translated to 1's and 0's. The difference between a DVD and CD is that DVD uses a more concentrated laser beam. This allows it to read very very small dots. Because the size of the dots is reduced we can save more data on DVD. Beyond little microdots, the big difference between DVD's and CD's is storage Capacity. CD's (compact discs) can hold between 640 - 700 MB's (megabytes) of information on a single disc. DVD's (Digital Video Discs) can hold 4.7 GB (gigabytes) of information on a single layer disc, and 8.5 GB on a dual layer disc.Beyond that, CD's hit the consumer market in 1983, and used a laser to read the media (disc) instead of magnetic technology. The standard amount of audio (time) on a CD with CDA sound files (compact disc audio) was approximately 72 minutes. Today, MP3 music files are about 1/10th the size of CDA audio. ***This unofficially works out to 10 MB per minute of audio with CDA, and 1 MB per minute of audio with MP3.***Beyond all those specifications, there is an old technology called Laser Disc, which was almost the same size as an LP (the big ones) record, but also used laser. Based on the the technology that would bring us CD's, the laser disc provided more data storage than a typical CD due to more surface area to write to. This technology was short-lived vs VHS due to the high cost. Even though the discs themselves were cheaper to produce, the equipment required to play cost significantly more than equivalent VHS players.In the future, HD DVD and Blue Ray technology will rerevolutionize laser technology. Future High Definition Television programs will be shown in 720p, 1080i or 1080p. These video qualities make watching Television as though it's photographic quality instead of dithered like current 480i. The capacity for HD DVD is about 35 GB's per dual layer disc, and Blue Ray is about 45-50 GB's per disc (unofficial specifications from respective Mfrs.)
