Thread: Computer Lingo ???

Mornin Gents,

I was directed to this category as a good place to ask LOTS of questions regarding "Computer for Beginners" "cough" as that would be me, and questions about digital cameras, downloading pictures etc. I can assure you that some of my questions will be so elementary, its embarrassing! And whilst I suppose I could look some of this stuff up....its easier for me to understand it when "real" people explain it.

So if Gents could be so kind as to lend a Lady a hand....here goes.

Whats the difference between a CD and a DVD....aren't they the same. Or one is for movies while the other is for music..??

I need to download some photographs onto a disc.....I'm supposed to get something that is re-writable...?? Ya know I just hate to go to Wal-Mart and stand there like an idiot not being sure which is what and then having to ask the 10 yr old standing next to me what to buy.

Any advice....most Welcome, Colleen

CDs can hold a lot of data (approx. 650MB) that's probably enough for that book your going to publish

DVDs can hold much more data (approx 4-8GB depending on type) and are better for video (movies) but can be used appropriately for storage of data as well.

The difference you will never see is how the data is encoded (burned) onto the discs.

So, if you wanted to make a soap-making documentary use a DVD. If you just want to store your computer files and pictures, a CD would probably be just fine.

As for downloading photos: If you want to keep adding photos to the same disc, then yes go with a re-writable. Depending on your PC, you may need to buy some CD burning software (Roxio, Nero, etc).

Best advice I can give you is to go to Best Buy and talk with them about what you have and what you want to do. They'll set you up fine.

Terminology: MB = megabyte. A measurement of data. I took the following from http://en.wikipedia.org/wiki/Megabyte to give you an example of what that means in real terms:

Depending on compression methods and file format, a megabyte of data can roughly hold:

* Roughly, a minute of near CD-quality MP3 compressed music (at 128 kbit/s)
* Approximately 100 pages of single-spaced 12 point font text in Microsoft Word. - translate that to approx. 65,000 pages (your book shouldn't be longer than that - will it????)
* Approximately 3 seconds of DVD-quality video

A digital photograph produced by a typical digital camera in 2005 might be 1–4 MB depending on the camera's image resolution and level of compression used.

- Approx. 160 pictures on average.

GB=Gigabyte (1,000 MB) From the same site:

# One gigabyte is roughly equal to 18 hours of MP3 music (at 128 kbit/s).
# One gigabyte is roughly equivalent to 11 hours, 40 minutes of Flash video (at 450x370).

Sorry for the techy stuff. I hope it isn't too foggy but I wanted to give you a foundation

Basics:

Main difference is capacity - a DVD will hold about 6 CD's worth of stuff, which is why DVD's are used for Movies.

If you are just looking to store pictures, then CDs will be fine, and you will get lots onto one.

To record once and keep, then you need cd-r
To record and then later re-record over the top, you need cd-rw

Hope that helps

Exactly what I said - just in English

I actually recognized some wording (single space 12 point font text) Thank You!! It helps to have something to associate these computer words to!

My homework assignment is to download all of my Photographs onto a disc, and then take them to the University student who is designing my Website (aka...the person who doles out my Homework ) I have to turn in my work on Friday.

Moving stuff around like that is pretty straight forward - even old dinosaurs like me can do it

The key phrase is 'Drag and Drop'. There are fancier ways, and no doubt some quicker ways, but the ole D&D works for me

I'm still sorda at "Point and Click".....Although! I have learned in the past week to drag and drop files into other files.....or files into folders, or folders into files...lol. Uhhh...my files are a weee bit of a mess!

Ok, now a small question ...
Do you have either a cd or dvd burner?
Would come in handy.

If it is for a single personally delivered amount of data, consider a memory stick.
Various sizes.

I'd avoid that. In my experience, the people at big box stores are dumb as nails, but, that doesn't stop them from recommending lots of crap to buy. If you have any smaller independent computer stores around, I'd try those instead. I buy all my parts from those kinds of stores, and, the staff is usually much more helpful because they themselves are the type of nerds who are into the stuff.

That's good too. With something small like CDs for data storage or other not too technical solutions, I have had good experiences with the Best Buy people locally and the employees seem to be into the same "geeky" stuff as the smaller guys are. I do alot with them and seem to be treated just fine.
