What is Big Data?

Two of the most popular buzzwords of recent years are ‘Big Data’. It hardly seems possible to read an IT article these days without it referring to this mystical entity. But what exactly is Big Data, why has it suddenly appeared, and why is everyone talking about it so much?

The thing to note first with regard to this subject is that there is no definitive definition of Big Data, as it is ultimately an abstract concept. The best way to define Big Data is to say that it essentially recognizes a process which has particularly accelerated in recent years; that of the rabid growth in the availability of both structured and unstructured data.

Although Big Data has been absorbed by the public collective consciousness in recent years, the concept has been understood among IT experts for over a decade. But because Big Data is an exponential concept, its relevance has grown massively of late. Many factors have contributed to its growth, not least that more and more institutions, organizations and businesses are increasingly interested in collecting information en masse whenever they have the opportunity to do so.


Why Lenovo is an Underrated Laptop

Tech Blog - Business Laptop - Lenovo UnderratedIf you own a business laptop, chances are it is probably an HP or Dell. These two companies have dominated the PC market for quite some time.  Lenovo is another big manufacturer that should be considered with these two.  Lenovo acquired IBM’s Personal Computing Division in 2005 and has been making what I consider the most valued machines since.


One of the great things about Lenovo laptops is their durability.  Lenovo ThinkPads are built with the intention of being dropped.  These machines have a magnesium alloy rollcage to prevent the screen and internals from smashing on impact.  Also Lenovo’s have a special keyboard that diverts any liquid spills out through the bottom of the laptop.  Most people prefer a wet desk to a fried laptop.
