You're going to have to explain this to me in photon-sized terms. I think a KB is bigger than an MB, but really don't know. I've never heard of Bcc except as the common local reference to Broome Community College.
When I was living on $975/month not including gas and food, (1995-6) internet wasn't even in question. Email? Ha. What does ISDN mean? Why hasn't anyone put out a reference book on this? Or why(ne), if it's been done, hasn't anyone told me?
Except that depending on context, KB = 1024 Bytes, and MB = 1024 KB. Round-number thousands anyhow though, and part of the time literally 1000.
"Each letter I type takes up a byte."
Careful -- Unicode screws with that explanation. (Each letter in English takes up one byte. Once you start mixing alphabets, some characters take up more than one byte.)
Historical usage, where bytes were different sizes on different machines, can remain a footnote for now. :-)
BCC = Blind Carbon Copy -- message recipients who don't show up in the email header. Like all the spam you receive that doesn't appear to be addressed to you -- you were blind copied. Or the email about the Chesapeake web site. (Your email software lets you do this too.)
ISDN: Google is your friend -- search on "define:ISDN"
ISDN is a public global network capable of transmitting voice, data and images at speeds up to 2 Mbit/s. The digital technique can transport more signals on the same telephone line than the traditional analogue technique and enables a range of new services. www.tst.dk/uk/publications/status2000eng/html_annex/bile.htm
Integrated Services Digital Network. A digital phone service capable of speeds from 57.6 K to 128 K. Provides two data channels, each with its own phone number, making simultaneous voice and data possible. www.56k.com/glossary.shtml
For comparison.... How do cable modems compare to ISDN, ADSL and satellite services?
ISDN (integrated services digital network), available through telephone lines, offers a maximum speed of 128 kbps -- a fraction of the bandwidth available through a cable modem connection. ADSL (asymmetric digital subscriber line) is a higher-speed alternative available over telephone lines, offering data rates of 1 mbps or more. That's comparable to a cable modem connection. Typically, however, ADSL services are more expensive than cable modem connections. Satellite services, such as DirecPC, offer up to 400-kbps download speeds, but require a dial-up modem for upstream communications, which is slow and cumbersome. (This info was from the cable-modem people at www.cable-modem.net.)
Or why(ne), if it's been done, hasn't anyone told me?
The same reason you'd use a blind-carbon-copy on paper correspendence,
To hide addresses if you're not sure every recipient wants everyone else to have their address (or when CC'ing a private mailing list that shouldn't get followups or doesn't want the list address quoted and archived randomly around the net),
When the list of recipients is so long that it takes up more than a screen or is longer than the message, and you don't want everyone to have to scroll through it to get to the text.
(I'm sure someone will suggest additional reasons, but those are the common ones.)
Hrm. I'd have preferred to bcc the email I just sent (I think I didn't include lj people this goround) but was afraid of spam filters nuking b/c of bcc...
I guess I'm spoiled now

Re: I guess I'm spoiled now
Each letter I type takes up a byte. Pictures take up far more space. If you look on your hard drive you can see the sizes of documents and pictures.
