I Vocabulary focus. Study the words and  word combinations, practise their translationspelling. Check your knowledge in the test. Play vocabulary game and set your own vocabulary game record.

II Watch the video and fill in the gaps with the words from  the list. There are several words you don’t need to use.



thicker; sticks; fragmented; store; cameras; storage; USB; format; portable; equipment; unplug; pictures; durable; plug into; computer; flash; expensive; fast; remove; disc; formatted; photography

We’ve also got other types of 1)_____ inside our computers that we can 2)_____ from the computer and take with us. We see 3)_____ memory very commonly used for this. These are different kinds of flash memory. These are the memory 4)_____ or memory keys you may be accustomed to seeing that just 5)_____  a USB connection. They might have 8 gig or 4 gig, or 16 gig or 32 gig. Because it is flash memory it gets relatively 6)_____ when you get up to larger amounts, but it’s a good way to 7)_____. A gig that’s a lot, and that’s a pretty inexpensive way to plug in a key, store some files on there, pull it out, take it to another 8)_____ or take it with you. We also have these other kinds of flash storage: SD. These types of storage are used a lot in 9)_____, they aren’t very 10)_____ in the way that they operate, they’re good for storing 11)_____, sometimes good for storing video as well. It’s a very small 12)_____, so it really applies very easily to 13)_____ technologies like cameras and like audio because you’re able to fit a whole lot of data into a very small amount of space. If you’ve ever worked on some older 14)_____, you may see something like a compact flash card. This is what you might see there, this is a 16 gig compact flash card, it’s a little bit bigger format. It’s a little bit more 15)_____ format too because it is bigger and it is 16)_____, but we’re starting to see the use of compact flash give way to perhaps some of these easier to use, these smaller types of formats such as the SD flash memory.

 III Watch the video. Choose the correct option to complete the sentences.



We didn’t use to think about hard drives as removable/reportable/replaceable storage devices, but these days they certainly are. These are good examples of external hard drives, here’s one that’s an all-for-one/all-in-one/all-for-nothing: it’s got a case and inside that case is a hard drive but it’s got different formats/formatted/forms on it. I can plug in a USB or an external PATA/SCSI/SATA connection into that particular drive. Here’s one that is a simple into face/ interface/face that connects to my computer, but you simply take an existing hard drive and just slam it in on top there. Now I can use that as external drive. When I want to use more story/strange/storage, I would remove that drive and then just put another one right in place.  So it makes it a very modular/modeled/popular, very easy for me to go the store, buy new hard drive, then just plug it into this stand-by/move-along/stand-alone interface that I can now use to access that particular drive. It makes it very easy to swap/switching/flop in huge amounts of data that way as well. If you work in a corporal/popular/corporate environment, you’re probably storing a lot of data, having hard drives to do that probably isn’t fanatically/financially/practically practical. The way that most people do that these days is with tape drives. You take magnetic tape, you stick into a mash-in/machine/pushing and you take all of the data from your computer system that’s on your hard drive and you simply floppy/copied/copy it to the magnetic tape. It’s copied digitally/literally/dietary and usually it’s copied with encryption as well. That way, if somebody gets their hands on this magnetic tape later, they wouldn’t be able to get any of your data off it. Usually these are in formats like this, where I can have multiply/imply/multiple tape drives in there simultaneously. In large environments, these very large environments, very large storage areas/arenas/scenes, we might have six/sixty/sixteen or thirty two or even more tape drives all running at one time so that you can take huge amounts of data, back them up denied/ overweight/overnight, and send them off site. That way, if something was to happen in your stability/facility/vicinity, you’ve still got a way to restore all of your data later on and you haven’t lost any of that imported/exported/important information.

IV Watch the video. Fill in the blanks in  the sentences.


Let’s see what we’ve learned from this 1)____ on storage devices. Here’s a 2)____ for you: “Which optical storage format can store up to eight point five gigabytes of information?” Do you recall which one dealt with that sort of size? It was a DVD, digital 3)____ disc; really it can store 8.5 gig. Obviously, I can do even more than that in my 4)____ as well. So I’ll give you 5)____ if you answered with either one of those. Another question: “Which drive technology uses 6)____ to store data instead of 7)____ platters?” We’re so used to magnetic platters with our hard drives. What type uses memory?  Well, that would be the 8)____ state drive or the SSD. And, lastly: “What type of 9)____ are most commonly used to connect to 10)____ hard drives?” We very often see different interfaces on hard drives, but there’s one that really we almost always see connecting our external hard drives together and that is usually USB, external SATA or even Firewire on some of these interfaces as well. So that’s one of the ways that we can 11)____ up. And, if you answered any of those, you’re probably going to find a hard drive out there that’s got some of those formats on there, very easy to find those pieces.

V Watch all the parts of the video.  Mark the following statements as True or False. Correct the false statements.

1.    Flash memory is a type of removable storage device.
2.    Flash key can hold from 8 to 32 GB.
3.    Flash memory is relatively inexpensive.
4.    Today SD flash memory is less popular than compact flash.
5.    External hard drives are not a type of removable storage devices.
6.    With magnetic tape you can copy all of the data from your computer system to the magnetic tape.
7.    Copies on magnetic tapes are not encrypted.
8.    Only two tape drives can work simultaneously.

 VI Watch all the parts of the video.  Answer the questions.

2.    What flash drives are widely used today? Which are better for music, video? Which are better for data and image storage?
3.    What are external hard drives like? How can we use them?
4.    How can magnetic tape drives be used by the companies? What are the advantages of magnetic tape storage?
