Spam: two definitions
relevant to the Internet:
1) related to email – virtually any and
all email that you don't want, in
particular unsolicited bulk email. The
use of Spam in email comes from Monty
Python's hilarious Spam sketch, which
was based on the canned meat..
2) related to Internet
Marketing and SEO
– Any
Internet Marketing method that a search engine
deems to be detrimental to its efforts
to deliver relevant, quality search
results. Some SE's
have written guidelines about what they
consider to be spamming, but ultimately
any activity a particular search engine
deems harmful may be considered spam,
whether or not there are published
guidelines against it. Example of spam
include the creation of nonsensical
doorway pages designed to please search
engine algorithms rather than human
visitors or heavy repetition of search
terms on a page (i.e. the search terms
are used tens or hundreds or times in a
row). These are only two of many
examples. Determining what is spam is
complicated by the fact that different
search engines have slightly different
standards.
Spiders: Software
created by a search engine, a.k.a.
crawlers, robots or bots, that
automatically scour the Internet,
reporting Web page contents back to a
search engine's index or database. These
are built by
search engines to build their index.
Streaming:
Process of transferring data in a
continuous and even flow, allowing users
to access and use a file while it is
transmitting.
System
Software:
Programs that control or maintain the
operations of a computer and its
devices, serving as the interface
between the user, the application
software, and the computer's hardware.
Two types of system software are the
operating system and utility programs. |
