Data Storage

Done for college. I myself consider it to be my first presentation which actually looks pretty good. And the presentation rocked in College - people liked it and everyone learned something.

Transcript

1. DATA STORAGE Hard disks, memory cards and the like.
2. SO WHAT IS DATA?
3. Data is information. Information of any kind - a sound, an image, text or anything really.
4. But wait, what's digital data?
5. It's basically all 1's and 0's.
6. HISTORY OF (DIGITAL) DATA STORAGE
7. Punch Cards?
8. Invented in 1725 by a textile worker, he used it to control looms. In 1890, it was modified by Herman Hollerith and used in America to take the Census in just ONE year. Earlier in 1880, the Census took EIGHT years.
9. INDIAN RAILWAYS
10. William's Tube (0.625 KB) First Random Access digital storage unit. SPEED = 1.2 ms/instruction 1947
11. Drum Memory (10 KB) Modern hard drive platter(disc) ka Pardada 1950S
12. The UNISERVO (128 bits/inch) First commercially- used tape drive. 1951
14. IBM 350(4.4 MB) 1956 First “modern” hard drive with fifty 24" discs that spun at 1,200 RPM.
15. Casette Tape(660 KB per side) Once used as a cheap way for storing data, it was later replaced by floppies. 1972
17. The Floppy Disk(1.2 MB) 1976 Tremendously popular consumer mass storage device. Was used widely for storing documents and even OSes.
18. IBM 3380 (2.52 GB) 1980 The first device to have gigabytes of storage.
19. ST-506 1980 Modern PC hard drive ka Baap.
20. ST-506
21. The Digital Audio Tape[DAT](1.3 GB) Was going to be high-end music recording device, but then later became storage for computers. 1987
22. The Compact Disc(700 MB) The format is still widely used. Its low price, small size and large storage capacity helped it to survive the rise of ZIP and JAZ disks. 1990
23. Was made to replace the floppy. But was too expensive and later the ZIP disk replaces it. MiniDisc MD Data(140 MB) 1993
24. ZIP Disk(100 MB) Was used to store large files. Quickly replaced floppy discs and was favoured over CD-Rs because it was re-writable. 1994
25. Seagate Barracuda (2.5 GB at first) First 7200 RPM drive, a speed that has become a standard now. 1996
26. IBM 170 Microdrive (had 170 MB when first released) Before flash memory was large and cheap enough for consumer electronics, these small drives went into the first iPods. Apple continued using them to the new iPod Classics. 1999
28. The Pen Drive (had 8 MB when IBM first released it) Became amazingly popular and quickly killed almost every other way of portable storage. 2000
29. The SD Card or memory card (had just 32 MB storage when first released) Gained widespread popularity in handheld devices like phones and cameras. Thin as a coin, these devices are no longer restricted by their physical size. 2000
30. SSDs or Solid State Drives With no moving parts, faster boot times and less physical space - they are now the new way we store digital media. 2008
34. VINTAGE COMPUTER ADS OF THE YESTERYEARS (or how far we've come)
40. Evolution of storage Storing information is an inherent part of the human race. As we evolve, we develop more efficient ways of storing data. Let us take the storage of music for example :
41. But wait, what's an SSD? (or how is it different from a normal hard drive?)
42. Let me handle that.
43. this is a normal hard drive
44. disc(s) magnetized needle(s) actuator arm
47. now all this activity results in quite a bit of sound and heat.
48. And because of the way it's built, it may be broken and made useless quite easily. If you don't believe me, try dropping a PC hard drive from your height to the floor.
49. Plus, there's fragmentation.
51. And all that's quite a bit of a nuisance.
52. Enter the SSD
53. SSDs are a faster, smaller, quieter and more reliable way of storing data. But as of now, they are expensive(and hence not as cheap as normal hard drives).
54. SSD = no moving parts Hard disk = moving parts
55. SSDs > Hard Drives
56. SSDs are (more or less) almost exactly the same as pen drives, external storage drives, memory cards, etc.
57. “ I think there is a world market for maybe five computers. ” - said in 1943 by Thomas J. Watson (CEO of IBM once upon a time) lagta hain budhau satya gaya tha...
58. I'm done. Thanks for your time. - by dhaheem rawuther( AKA alvasrawuther) @alvasrawuther mr.alvas.r@gmail.com alvasrawuther.tumblr.com fb.com/alvas.rawuther TY Rushabh for pointing me towards that Discovery Science video. It was helpful :)
