Cross Posting: This refers to the practice of posting the same message
to different newsgroups.
Binaries: These refer to the non text part of a message—usually
pictures, video files, audio files- that are attached with the message.
alt.binaries is an NG that is dedicated to posting messages
with binary content.
Retention Time: NNTP servers do not store topics indefinitely. The
duration for which they retain the topics is the retention time.
This varies from server to server.
Multi-part Message: This applies to messages with large attachments.
Since servers have limits on the file attachment sizes, users
split the attachment over more than one message. These messages
constitute a multi-part message. Newsreaders that support multipart
messages are capable of identifying the different parts of a
message and joining the attachment to recreate the complete file.
Message Encoding: This is a issue that is applicable more to binary
messages. Since NNTP servers were designed to handle text
data, to be able to pass binary data through them the message has
to be encoded. Different encoding schemes exist, like yEnc, MIME
and UUE. A user intending to download binaries should choose a
client capable of handling files encoded in either of these
schemes. yEnc is the most frequently used scheme in alt.binaries.
Header and Message Body: A header is that part that carries metainformation—
like NG address, poster address, subject, encoding
scheme etc. The message body carries the actual message or
attachment. Most clients can download just the headers of messages
allowing you to judge whether to download the message
body as well. This saves a lot of time and bandwidth.
