New Fastest Speed For A Network? Researchers Were Blasting Away 186 Gigabits of Data Per Second!

Upload / DownloadAccording to Cnet‘s article “Supercomputer network blasts torrent of data,” various experts in various fields with the same goal in mind, faster network, had accomplished a new feat together in blasting data across their special network at 186 Gigabit per second.  It all took place at SuperComputing Conference of 2011.  Imagining this, by uploading and downloading single sided double layer DVD data (8.7 GB) at this speed, you would get 2.489 DVDs of 8.7 GB size per second; 149.34 DVDs of 8.7 GB size per minute; 8,960.4 DVDs of 8.7 GB size per hour; 215,049.6 DVDs of 8.7 GB size per day.  How about Blu-ray disk of 50 GB type?  You would get 0.433 Blu-ray disk of 50 GB size per second; 25.98 Blu-ray disks of 50 GB size per minute; 1,558.8 Blu-ray disks of 50 GB size per hour;  37,411.2 Blu-ray disks of 50 GB size per day.

With such a speed, I bet some researchers still want faster network.  Why?  If I’m them and have terabyte after terabyte of data to transfer, I definitely think that 186 Gigabit per second is still kind of slow.  Think about it, at 186 Gigabit per second, researchers can only upload and download 1,823.04 terabytes of data per day.  If Cnet’s report “Supercomputer network blasts torrent of data,” is true that petabytes of data being generated at various big research institutes for however long, at such a rate, someone will eventually start complaining how slow it’s for them to be able to only transfer 1.780 petabyte per day.  Of course, everyday users like us would think of such speed is superman.

According to Eric Schmidt, Google CEO, around five exabytes of data get generated every two day period by the Internet (source:  http://techcrunch.com/2010/08/04/schmidt-data/); this TechCrunch article was written in August 4th of 2010.  Imagine as we moving forward, the Internet would need a lot more of data.  The future of the Internet will include the additional evermore growing mobile devices on the top of all devices and computers that we already have today.  1.780 petabyte per day is simply too slow for the Internet by then, I think.  Here is a simple calculation of five exabytes in two days equates to this many terabytes; 1,048,576 terabytes are equal to one exabyte, and so we take this number times five and get 5,242,880 terabytes.  Yep, it takes this much terabytes for every two day period to satisfy the Internet nowadays.  It makes me wonder how much bigger this number will be in 2020 or so.

Using Mac To Burn An Image, How?

In case you don’t know how to burn an image on Mac, I’ll show you how to do so in this post.  What do I mean by burning an image?  No, it’s not like I’m telling you to take a picture, light a fire, and in the process may hurt yourself.  It’s more of when you have downloaded a file with the .iso extension, and need to have this file to be burned onto a CD or DVD.  There is a big different between burning an image and just burning an image, and I’m not talking about burning a real image, but I mean — oh, OK, I’ll stop this before you get overly confused.  What I’m trying to say is that you’re not actually burning an image if you just clone the data such as copying the same file with .iso extension onto a disc (i.e., CD or DVD).  By burning an image, you actually have to use a specific feature of burn an image from your CD/DVD burning software, because burn an image feature allows you to make the file with .iso extension becomes bootable.  Why is this important?  For an instant, when you download a Linux operating system, you can use burn an image feature of your burning software to make the Linux file becomes bootable — so the next time you insert the Linux CD/DVD that you had burned into a fresh boot computer, it will recognize the Linux CD/DVD so the installation process can start.

Alright, enough with that already, so how do I actually burn an image using Mac?  It’s simple really, and you don’t need to buy an app or third party software to do so.  Latest Mac OS X (i.e., Snow Leopard) has an application which is known as Disk Utility, and this very application will do the job.  So let fire up your Disk Utility by going to Applications >> Utilities >> Disk Utility.  At Disk Utility, go to File >> Open Disk Image, and choose your file with .iso extension.  Click on the file with .iso extension on the left panel of Disk Utility, and click on Burn icon at the top of Disk Utility.  Just make sure you have placed a blank CD or DVD inside your Mac before clicking on the Burn icon.  That’s all, really!  Oh, one last thing, Mac tends to verify its burning content before it says good bye, have a good day to you, but this process can be extremely bothersome and time consuming.  If you don’t care or have confidence in Mac’s ability to burn an image or whatever, then you can click on the skip option when Mac tries to verify the burning content.  Clicking on skip verify option so your burning process can complete faster.

To clean up the whole process, after you finish burning an image with Mac, you can go to your Desktop, right click on the mounting image and eject it.  Inside Disk Utility, make sure to right click on the file with .iso extension on the left panel, and click on remove to remove it from your Disk Utility.  Have fun with burning an image on Mac!
