The hacker culture is a subculture of individuals who enjoy the intellectual challenge of creatively overcoming and circumventing limitations of systems to achieve novel and clever outcomes. The act of engaging in activities (such as programming or other media) in a spirit of playfulness and exploration is termed "hacking". However, the defining characteristic of a hacker is not the activities performed themselves (e.g. programming), but the manner in which it is done: hacking entails some form of excellence, for example exploring the limits of what is possible, thereby doing something exciting and meaningful. Activities of playful cleverness can be said to have "hack value" and are termed "hacks" (examples include pranks at MIT intended to demonstrate technical aptitude and cleverness). The hacker culture originally emerged in academia in the 1960s around the Massachusetts Institute of Technology (MIT)'s Tech Model Railroad Club (TMRC) and MIT Artificial Intelligence Laboratory.
In the computer security context, a hacker is someone who seeks and exploits weaknesses in a computer system or computer network. Hackers may be motivated by a multitude of reasons, such as profit, protest, challenge, enjoyment, or to evaluate those weaknesses to assist in removing them. The subculture that has evolved around hackers is often referred to as the computer underground and is now a known community.
While other uses of the word hacker exist that are not related to computer security, such as referring to someone with an advanced understanding of computers and computer networks, they are rarely used in mainstream context. They are subject to the longstanding hacker definition controversy about the term's true meaning. In this controversy, the term hacker is reclaimed by computer programmers who argue that someone who breaks into computers, whether computer criminal (black hats) or computer security expert (white hats), is more appropriately called a cracker instead. Some white hat hackers claim that they also deserve the title hacker, and that only black hats should be called "crackers".
A retail or a shop is a business that presents a selection of goods and offers to trade or sell them to customers for money or other goods. Shopping is an activity in which a customer browses the available goods or services presented by one or more retailers with the intent to purchase a suitable selection of them. In some contexts it may be considered a leisure activity as well as an economic one.
In modern days customer focus is more transferred towards online shopping; worldwide people order products from different regions and online retailers deliver their products to their homes, offices or wherever they want. The B2C (business to consumer) process has made it easy for consumers to select any product online from a retailer's website and have it delivered to the consumer within no time. The consumer does not need to consume his energy by going out to the stores and saves his time and cost of travelling.
The shopping experience can range from delightful to terrible, based on a variety of factors including how the customer is treated, convenience, the type of goods being purchased, and mood.
