How easily to remember the different layers in OSI Reference Model?

How easily to remember the different layers in OSI Reference Model?

Whilst posting about "An easy way to remember Rahu Kalam", I just recalled about a simple and a similar sentence that we learnt during college days to remember the different layers in Computer Networks. It was a book titled "Computer Networks" by Andrew S. Tanenbaum that was prescribed for the syllabus.

The simple sentence was 'Please Do Not Throw Sausage Pizza Away'. Now we can remember the following layers simply:

1. Physical
2. Data Link
3. Network
4. Transport
5. Session
6. Presentation
7. Application

When I did a quick Internet Search of this statement itself, I just got a few more interesting sentences to make one remember the seven layers. Check it out here from TcpIp guide website.

PDF is by far the most common document formats that have been used across the world by everyone. There are cases, when we need to split a PDF document into multiple PDFs and sometimes we may need to merge multiple PDF documents into a single document. Editing such PDF documents stipulate that we Acrobat Reader and related tools, which are rather heavy and cumbersome to install.

I just found out a few quick and easy PDF Split and Merge utilities that help us in this direction. I would like to share them here for the benefit of other readers who might be looking out for a similar solution:

1. PDF Hammer
2. RPTEA Split Merge (supports even zip input)

A Quick Online Zipping Solution

A Quick Online Zipping Solution

We always have an easy way to zip and unzip files online with quick nifty little utilities like WinZip, UltimateZip and now starting from Windows XP, there is a builtin support to compression and decompression by way of 'Compressed Folders'. However, with all these, there are cases when we felt that if there was a webservice that would support zipping and unzipping online. One such case or situation might be if Compressed Folders does not work properly because of conflict with a bad deinstallation of another archiving software.

I just came across a cool website called NippyZip, which exactly addresses this requirement. It supports upto 5024 KB of input files and after uploading, it compresses them and streams out a zip file. Since the website does not require any registration, you are also not required to hold or give out an active email address to it anymore.

After zipping out the input files, it also provides an option to add more files to the output archive.

I just thought of sharing out this with other readers too. Bookmark this URL so that you can avail the benefits of a cool new online zipping solution on the move.
