But the question should be: why do you want to program in the first place? If you are interested in it because it seems fun, then any language will do. But I have a feeling some of you have bills to pay, and you're thinking it wouldn't be so bad if programming could foot some of that. Now the question is more specific: which programming language should you learn to make money? Now the question is ponderable, but be warned, the answer won't be the same for everybody. The good news is that all popular languages are pretty fair in terms of compensation. Learning How to Code Has Never Been Easier. Programming isn’t just a niche specialization anymore, rather a necessity for tech-professionals regardless of the industry in which they work. Thankfully for them, it couldn’t be any easier.As such, there’s a big push lately to make coding literacy more widespread among the general populace.
Even Mayor Bloomberg is getting in on the act, pledging to learn basic coding in 2012 as his New Year’s resolution. For those who want to learn to code, there are a number of online school coding programs that can guide them through the process. The main players are Codecademy, Team Tree House and Code Year, each with their own strengths, weaknesses and selling points—all who make it easy. Codecademy Probably the most popular website at the moment for those looking to learn coding is Codecademy, a platform that emphasizes doing while learning. Treehouse Though it doesn’t have the name recognition of Codecademy just yet, Team Tree House is nevertheless a powerful way to learn coding. Basics_introduction_2.

SEEK TIME - is the time taken for a hard disk controller or pointer to locate a specific piece of stored data. Other delays include transfer time (data rate) and rotational delay (latency). LATENCY - is the time required to perform some action or to produce some result. Latency is measured in units of time — hours, minutes, seconds, nanoseconds or clock periods.
THROUGHPUT- is the amount of data that can traverse through a given medium ( Bandwidth is nothing but the diameter of your medium ) FAULT TOLERANCE – Your system should have the ability to respond gracefully and continue the operations during the unexpected failure of your system like Power,Hardware,Data corruption,etc. RAID - Collection of Disks storing the same data ( mirroring) in different places .

Having grown up with the Internet, smartphones and tablets, they’re often extraordinarily adept at interacting with digital technology. But Mitch Resnick, who spoke at TEDxBeaconStreet, is skeptical of this descriptor. Sure, young people can text and chat and play games, he says, “but that doesn’t really make you fluent.” Mitch Resnick: Let's teach kids to code Fluency, Resnick proposes in this TED Talk, comes not through interacting with new technologies, but through creating them. The former is like reading, while the latter is like writing. The point isn’t to create a generation of programmers, Resnick argues. In his talk, Resnick describes Scratch, the programming software that he and a research group at MIT Media Lab developed to allow people to easily create and share their own interactive games and animations.
