“The world’s first 4K Ultra HD laptop is about to hit the market.
The screen on the Toshiba Satellite P55t will house as many as four times the pixels as a standard FHD display, delivering a native 3840 x 2160 resolution with a 282 PPI density. 4K Ultra HD is cutting-edge technology that produces crisper, more detailed images on televisions and computer screens. But it comes with a price. The Toshiba 4K laptop, announced Tuesday and available April 22, will sell for $1,500.
Toshiba is also refreshing its Satellite Series mainstream laptops with thinner chassis designs, enhanced audio, optional LED backlighting and increased storage capacity. Those new machines will all become available June 22.”

“The book was a compilation and extension of known rules for solvingquadratic equationsand for some other problems, and considered to be the foundation ofalgebra, establishing it as an independent discipline. The wordalgebrais derived from the name of one of the basic operations with equations (al-ğabr) described in this book. The book was introduced to the Western world by the Latin translation ofRobert of ChesterentitledLiber algebrae et almucabola,hence “algebra”.
Since the book does not give any citations to previous authors, it is not clearly known what earlier works were used by al-Khwarizmi, and modern mathematical historians put forth opinions based on the textual analysis of the book and the overall body of knowledge of the contemporary Muslim world. Most certain are connections with Indian mathematics, as he had written a book entitled Kitāb al-Jamʿ wa-l-tafrīq bi-ḥisāb al-Hind (The Book of Bringing_together and Separating According to the Hindu Calculation) discussing the Hindu-Arabic numeral system.”
This is an excellent article about the anatomy of frames, the pieces that help us communicate with ease .
Excerpt (2009, 1)
"The first area to cover is simply proper terminologies. It is important to understand the difference between a Frame and a Packet.
A Ethernet Frame is a physical layer communications transmission, comprised of 6 fields which are assembled to transmit any higher layer protocol over an ethernet fabric.
A IP Packet is a formatted unit of data which can be transmitted across numerous physical topologies including Ethernet, Serial, SONET and ATM.
The important thing to understand is that a frame always refers to the physical medium. References to enhancements in the physical medium like larger than standard ethernet frames are called “Jumbo Frames”, not “Jumbo Packets”
A packet is reference to a message transmission which is compiled in software and delivered to a physical medium so that it can be transported. An example of this includes the means by which you are viewing this post. You may be reading this from your laptop at home which is connected to your home network via wireless ethernet. You then may have a DSL or Cable modem which communicates via Ethernet on your home network and by Cable or DSL through the interface that exits your home premise. That connection is typically collapsed into some type of optical switch in your Internet carriers network infrastructure, later transmitted through your carriers network core likely via High Speed routers connected at OC-192, which is 10Gbps SONET. Ultimately you arrive at a NetApp data center in either RTP or Sunnyvale where your request traverses Ethernet on one of NetApp’s community web servers. The entire path of communications transmitted packets that were ultimately several HTTP-GET requests to view the text you are now reading.
You may be reading this and saying, why be so specific? The reason is simply communication. If a storage expert is to effectively collaborate with a network expert then the proper terminologies need to be used so the collaboration is effective.
To discard this would be like a network engineer coming to you, the storage engineer and stating that they need their network management application installed on a share which was Fibre Channel mounted to RAID set of 15K RPM SATA disks. “
A great beginning series on the history of Algebra by the guy who has reinvented the elementary school framework by creating the beautiful online academic experience that is Khan Academy, birthed by Salman Khan, who I’m sure you all have heard of by now.
