Scripting languages are interpreted within their applications, rather than compiled to run directly by a microprocessor. This distinction makes them slower than the kinds of development efforts found in most commercial software. But most scripting languages are usually easy to use, and are often used both by professional programmers and power users.

A term you might hear when talking about API's (sharing computing). It is a set of standards for exchanging information between computer applications. EDI is most often used as a way to send the electronic equivalent of structured documents between different organizations. One study showed that firms that used EDI decreased their error rates by 82 percent, and their cost of producing each document fell by up to 96 percent.

When computers in different locations can communicate with one another, this is often referred to as distributed computing. Ex: the World Wide Web The World Wide Web, like many other distributed computing services, is what geeks call a client-server system. Client-server refers to two pieces of software: a client (software program) that makes a request and a server that receives and attempts to fulfill the request. Another example is smartphone voice recognition software, such as Apple's Siri. Voice recognition typically requires computing power far greater than that held on a smartphone, so Apple sends your voice to a more powerful collection of servers for processing and interpretation.

As a layer cake. Think about computer hardware as being at the bottom of the layer cake. The next layer is the operating system, the collection of programs that control the hardware. Windows, Mac OS X, iOS, and Linux are operating systems. On top of that layer are applications—a range of which include end-user programs like those in Office, apps that run on smartphones, and the complex set of programs that manage a business's inventory, payroll, and accounting. At the top of the cake are users.

Issues of content adjacency and user attention can make social networking ads less attractive than ads running alongside search and professionally produced content sites. Google enjoys significantly higher click-through rates than Facebook. Rates are lower since users of social sites are there to engage friends, not to hunt for products. They are less likely to be drawn away by clicks.

Much of bitcoin's appeal comes from the fact that bitcoins are transferred from person to person like cash, rather than using an intermediary like banks or credit card companies. Getting rid of card companies cuts out transaction fees, which can top 3 percent. Bitcoin could be a boon for cross-border remittance and in expanding e-commerce in emerging markets. A bitcoin transfer would be immediate and could theoretically eliminate all transaction fees.

Bitcoins are transferred from person to person like cash. Instead of using a bank as a middleman, transactions are recorded in a public ledger (known as a blockchain in bitcoin speak) and verified by a pool of users called miners. While the ledger records transactions, no one can use your bitcoins without a special password. The technology behind this is open-source and considered rock solid. Passwords are virtually impossible to guess; and verification makes sure no one spends the same bitcoins in two places at once.

The major Bitcoin exchanges don't accept credit cards-- because that whole anonymity problem-- so instead, youre concourage to purchase Bitcoin by adding your bank account information to a site like Coinbase, and transferring money that way.

Bitcoin's founder is Satoshi Nakamoto, which is a  Pseudonym . Nakamoto "released Bitcoin to the world at the beginning of 2009, but said he had been working on it since 2007,"

In 2012, the exchange rate for 1 Bitcoin = $10 April 4, 2013 = $140  And in November 2nd, 2017 its worth $7000.

In the US, the answer is probably yes, but it still depend on what state you're in. Doing something illegal with Bitcoins---like bringing someone of buying drugs -- is still illegal.

New Bitcoins are created in a process called "mining," which involves Bitcoin users attempting to figure out a complex mathematical solution related to the cuttent number of Bitcoins. Like finding a missing piece of a puzzle. Whomever finds the puzzle piece wins a certain number of Bitcoins, and the process starts all over again.

People seeking privacy in their financial transactions-- for legitimate or illegitimate reasons -- might also use Bitcoin because it's more anonymous that financial transactions using credit or debit cards.

A Bitcoin wallet is a service that holds your Bitcoin for you. Unlike bands, Bitcoin wallet firms don't generally invest the money you deposit with them. But there's a catch -- Bitcoin wallets don't have the FDIC (Federal Deposit Insurance Corp.) backing that insures American's bank deposits up to $100,000.

You hold on to Bitcoins by setting up a virtual wallet, either on your computer-- Although storing you Bitcoin wallet only on your computer is about as secure as stuffing hundred dollar bills under your mattress.
