News
The new REVCOM NewsDesk will give you a one-stop-shop for all the
announcements made by the NEC.
All the documents in this section, along with the archives and magazine sections mentioned below are (where possible) available in four different formats, you just have to chose which one you want. The four formats are: plain text, RTF, HTML, and PDF. See the explanation at the bottom of this page for more information about these formats.
The main benefits of RTF are that:
HTML is similar to RTF in that it is basically made up of the text that is
required, and then tags are added to enhance the presentation. The main
differences between HTML and RTF are:
The only real drawback with PDF files is that not very many programs can
read PDF files. However, this is not the drawback it could be, because the
programs that do exist as a rule are free and run on lots of different
computers. For unix computers running X-Windows look for a program called
XPDF. For most other systems (as well as some unixen) you want Adobe
Acrobat. To get Acrobat go to the
Adobe Acrobat
site, chose the version you want, download and install the program.
An explanation of the file formats
As mentioned above, the documents stored on the REVCOM web site are available
in four different formats. These formats are
Plain Text
Documents stored in plain text format contain exactly what the name implies.
These documents contain no presentation formatting instructions at all - they
are exactly as they would have been if someone had sat at a traditional
typewriter and types them in. Any person and any program should be able to
read these documents with ease, but their use is very limited.
RTF
RTF, or Rich Text Format, is basically plain text on steroids. It is just the
same as plain text mentioned above, except that it has embedded in it
formatting information called tags. These tags tell programs that understand
them how to show (render) the document. It can do things like underline,
emphasis, or italicise text. It can change the size that the text is
shown as so that titles for example can be bigger.
it is probaby the most widely supported format after plain text; the
vast majority of editors and printing systems understand RTF to some
extent.
it doesn't matter if you can't. Even if your computer cannot support
RTF files, because they are just plain text files with tags added it is
not too diffecult to ignore or remove the tags and end up back with
plain text.HTML
HyperText Markup Language is what makes the world go round. To be more
acurate, it is what makes the World-Wide-Web go round because HTML is the
language that is used to write WWW pages.
The documents stored in HTML formaton the web site are split down in to
another two types. Firstly, you can access the documents directly, as
though they are part of this site. Secondly, they will be available in
.ZIP format so that you can download the entire document in one go and
view it later. You will however need a program for your computer to
un'ZIP' the documents before you can use them.
While RTF is intended to enable a plain text file to be rendered nicely
HTML's main use is for document browsing - the easy navigation between
seperate but related documents quickly.
When viewing a document on screen, or printing onto paper, RTF provides
much more control over the end product than HTML. HTML depends very
much on the browser (the program used to access the HTML) to decide
now to show the document.
RTF files do not easily enable you to jump to other parts of the
document, or to other documents. HTML files enable this facility.
With this you can jump from where you are in a document to any other
part of the document, to other documents on the same computer, or even
any document on another computer.
PDF
Portable Document Format (PDF) files are effectively the combination of RTF
and HTML (although technically they are nothing like either). With PDF files
you have the same (or better) control over the rendering of the document that
you have with RTF, while still having the hyperlink facility to jump about
inside and outside the document.
