Online Shopping

Online shopping is the process whereby consumers directly buy goods or services from a seller in real-time, without an intermediary service, over the Internet. If an intermediary service is present the process is called electronic commerce. An online shop, eshop, e-store, internet shop, webshop, webstore, online store, or virtual store evokes the physical analogy of buying products or services at a bricks-and-mortar retailer or in a shopping mall. The process is called Business-to-Consumer (B2C) online shopping. When a business buys from another business it is called Business-to-Business (B2B) online shopping. Both B2C and B2B online shopping are forms of e-commerce.

History

In 1990 Tim Berners-Lee created the first World Wide Web server and browser. opened for commercial use in 1991. In 1994 other advances took place, such as online banking and the opening of an online pizza shop by Pizza Hut. During that same year, Netscape introduced SSL encryption of data transferred online, which has become essential for secure online shopping. Also in 1994 the German company Intershop introduced its first online shopping system. In 1995 Amazon launched its online shopping site, and in 1996 eBay appeared.

payment

Online shoppers commonly use credit card to make payments, however some systems enable users to create accounts and pay by alternative means, such as:

• Debit card
• Various types of electronic money
• Cash on delivery (C.O.D., offered by very few online stores)
• Check
• Postal money order
• Reverse SMS billing to mobile phones

Some sites will not allow international credit cards and billing address and shipping address have to be in the same country in which site does its business. Other sites allow customers from anywhere to send gifts anywhere. The financial part of a transaction might be processed in real time (for example, letting the consumer know their credit card was declined before they log off), or might be done later as part of the fulfillment process.
 

Advantages/Disadvantages

Advantages

• Convenient
  Convenience includes the overall ease of finding a product, time spent on shopping, minimization of overall shoppoing effort (Schaupp & Belanger, 2005). Online shopping allows consumers to shop at the convenience of their own home, and to save traveling time to retail stores and spend their time on other important tasks and hobbies. Researchers idenfity convenience as a 'fundamental objective' related to online shopping (Schaupp & Belanger, 2005). This is relevant to 72% of online shoppers' claim that they would rather surf online than go to retail store to attain information about a product (Lokken et al., 2003). According to a study, 72% of online shoppers chose convenience over privacy (Bhatnagar, Misra, & Rao, 2000). In addition to ease of finding products online and shopping time reduction, consumers can shop without time limitation with 24-hr access at their convenience because the World Wide Web never closees. Lokken mentions 24-hr access as a beneficial characteristic of online shopping (Lokken et al., 2003). Also, consumers can exchange information online through chatting and discussion forums to help them make wise consumer decisions.
• No need for vendors and no pressure to buy
  Online shopping benefits both the society as a whole and individuals. The society can save human resources when consumers help themselves by browsing freely online instead of asking for assistance from vendors. In addition, consumers are freed from the pressure to buy from the vendors and can spend more time to make wise purchase decisions. But it is imorpant that Web sites have good product descriptions because it is one of the significant condition that satisfy consumers (Limayem, M., Khalifa, M., & Frini, A., 2000).
• "Infinite shelfspace" available
  Consumers desire a variety of products because they look for the right product that will fully satisfy them. There is infinite variety of products available online because online shopping allows consumers to browse through products that are made all around the world without geographical boundaries.
• Able to compare product price and features
  With the online tools that enable product comparison, consumers can compare product prices and features to make a better decision with less effort. More details are included in solutions section.

Disadvantages/Concerns

• Enjoyment of retail shopping lost
  Many enjoy shopping with others and it is often a good way to make social connections. When shopping independently online, the enjoyment is lost.
• Privacy and security issues
  Privacy is the number one reason that non-online shoppers do not shop online. Almost 95% of Web users have declined to provide personal information to Web sites at one time or another when asked (Hoffman, Novak, & Peralta, 1999). Another recent study has found that privacy was the top concern of customers while security ranked bottom (Schaupp & Belanger, 2005). This proves that many do not trust the privay of the Internet and are concerned with their credit card fauds, unwanted solicitation, and use of their information for other purposes. Security of Web sites is not the top concern because many shop on Web sites that they trust so that other factors appear to be more important than security.
• Access to the Internet and computer necessary
  Because one needs money to buy a computer and to have internet connection, online shopping seems to be limited people of reasonable amount of income. Also, since it is harder to learn computer at an older age, the elderly people tend shop at traditional retail stores.
• Product category risk
  Product category risk is related to functional products such as apparel, perfume, and electronics, that have functions that cannot fully be expeirenced online. Online shopper are worried that the products will not be what they have expected by viewing online. This is a clear disadvantage of onlins shopping because it shows that "[t]he likelihood of purchasing on the Internet decreases with increases in product risk" (Bhatnagar, Misra, & Rao, 20000, p. 100). Apparels in particular had negative rating in online shopping because of it is difficult to feel and see the texture of color online that is incomparable to going to a retail store, even with magnifying tools online. Also, one cannot try on a clothing before buying it online, so it would be very inconvenient if the size did not fit the person and he/she had to return it.
• Too many choices
  Although having access to a very large number of products is highly desirable, consumers have limited cognitive resources and may simply be unable to process the potentially vast amounts of information about these alternatives (Haubl & Trifts, 2000). Online stores need to provide the variety in an organized way that will facilitate shopping online.

Ebay

Bbay is an online store where people or companies can sell or buy goods through the internet, so if u are too lazy to go to a real shop this will be great. Ebay might be better than real because you wont be able to find a real store which might contain all the goods that ebay has, also you can buy from all over the world , like maybe there are some stuff that not available in your country so u can buy and ship it from ebay. Ebay will also gives online banking services which might be safer than using the credit card directly as some poeple thinks, also one of the things which made ebay succesfull and uniqe as the persident of ebay John donahoe says.

Windows 7 Sins: The case against Microsoft and proprietary software

The new version of Microsoft's Windows operating system, Windows 7, has the same problem that Vista, XP, and all previous versions have had -- it's proprietary software. Users are not permitted to share or modify the Windows software, or examine how it works inside.
The fact that Windows 7 is proprietary means that Microsoft asserts legal control over its users through a combination of copyrights, contracts, and patents. Microsoft uses this power to abuse computer users. At windows7sins.org, the Free Software Foundation lists seven examples of abuse committed by Microsoft.

1. Poisoning education: Today, most children whose education involves computers are being taught to use one company's product: Microsoft's. Microsoft spends large sums on lobbyists and marketing to corrupt educational departments. An education using the power of computers should be a means to freedom and empowerment, not an avenue for one corporation to instill its monopoly.

2. Invading privacy: Microsoft uses software with backward names like Windows Genuine Advantage to inspect the contents of users' hard drives. The licensing agreement users are required to accept before using Windows warns that Microsoft claims the right to do this without warning.

3. Monopoly behavior: Nearly every computer purchased has Windows pre-installed -- but not by choice. Microsoft dictates requirements to hardware vendors, who will not offer PCs without Windows installed on them, despite many people asking for them. Even computers available with other operating systems like GNU/Linux pre-installed often had Windows on them first.

4. Lock-in: Microsoft regularly attempts to force updates on its users, by removing support for older versions of Windows and Office, and by inflating hardware requirements. For many people, this means having to throw away working computers just because they don't meet the unnecessary requirements for the new Windows versions.

5. Abusing standards: Microsoft has attempted to block free standardization of document formats, because standards like OpenDocument Format would threaten the control they have now over users via proprietary Word formats. They have engaged in underhanded behavior, including bribing officials, in an attempt to stop such efforts.

6. Enforcing Digital Restrictions Management (DRM): With Windows Media Player, Microsoft works in collusion with the big media companies to build restrictions on copying and playing media into their operating system. For example, at the request of NBC, Microsoft was able to prevent Windows users from recording television shows that they have the legal right to record.

7. Threatening user security: Windows has a long history of security vulnerabilities, enabling the spread of viruses and allowing remote users to take over people's computers for use in spam-sending botnets. Because the software is secret, all users are dependent on Microsoft to fix these problems -- but Microsoft has its own security interests at heart, not those of its users.

You can help!

Free software operating systems like GNU/Linux can do the same jobs as Windows, but they encourage users to share, modify, and study the software as much as they want. This makes using a free software operating system the best way for users to escape Microsoft and avoid becoming victims of these seven sins. Software and computers will always have problems, but by using free software, users and their communities are empowered to fix problems for themselves and each other.
You can get more information about each of the sins and how to escape them at windows7sins.org. Please sign up there for campaign news and action alerts to help raise awareness about Microsoft's abuses, the problems with Windows 7, and the importance of free software!

Disadvantages Of Email

Spoofing and Spamming It is relatively easy to write a program that will give a fake address in the 'From' field of an email, thus leading the receiver to believe the email is from a trusted source. Email viruses do this routinely. Many individuals have found it funny to send an email as though the President of the USA. this is spoofing. Spamming is using email to conduct a junk mail campaign. It is so easy to do that unregulated it can flood people's inboxes.

Virus A harmful piece of code that attaches itself to programs or files. A virus is capable of replicating itself once it is opened . for example , when a new program is opened it can be  further cue for the virus to replicate it self , allowing it to spread rather like a biological virus.

Worm A particular species of virus that is capable of replicating itself in great volumes once installed without further files being opened . furthermore, because they are capable of 'burrowing' into a system without human assistance, some worms can allow their creators to take control of computer systems remotely.

Trojan Another virus in the form of a piece of code, named after Trojan horse. it is usually dressed up as an attractive attachment or download but many harbour a unwelcome payload. once installed on a user's machine it can do damage to a user's system and possibly take control of the user's machine.
