3. Connect to the Internet
3
Before connecting to the
Internet, you must determine how
you're going to connect to the
Internet.
Are you going to be connecting to
the Internet using a modem or a
broadband Internet connection?
Or do you want to use your
smartphone to provide Internet
service to your computer?

4. Types of Internet service
4
Dial-up: This is generally the slowest type of Internet connection, and you
should probably avoid it unless it is the only service available in your area.
Dial-up Internet uses your phone line, so unless you have multiple phone
lines you will not be able to use your landline and the Internet at the same
time.
DSL: DSL service uses a broadband connection, which makes it much faster
than dial-up. DSL connects to the Internet via a phone line but does not
require you to have a landline at home. And unlike dial-up, you'll be able to
use the Internet and your phone line at the same time.
Cable: Cable service connects to the Internet via cable TV, although you do
not necessarily need to have cable TV in order to get it. It uses a broadband
connection and can be faster than both dial-up and DSL service; however, it
is only available where cable TV is available.

Satellite: A satellite connection uses broadband but does not require
cable or phone lines; it connects to the Internet through satellites
orbiting the Earth. As a result, it can be used almost anywhere in the
world, but the connection may be affected by weather patterns.
Satellite connections are also usually slower than DSL or cable.
3G and 4G: 3G and 4G service is most commonly used with mobile
phones, and it connects wirelessly through your ISP's network.
However, these types of connections aren't always as fast as DSL or
cable. They will also limit the amount of data you can use each
month, which isn't the case with most broadband plans.

6. Modem

Once you have your computer, you really don't need much additional
hardware to connect to the Internet.
The primary piece of hardware you need is a modem.
Dial-up access uses a telephone modem, DSL service uses a DSL modem,
cable access uses a cable modem, and satellite service uses a satellite
adapter.

7. Router
7
A router is a hardware device that allows you to connect several
computers and other devices to a single Internet connection, which is
known as a home network.
Many routers are wireless, which allows you to create a home
wireless network, commonly known as a Wi-Fi network.

8. E-commerce
8
E-commerce is a transaction of buying or selling online.
Electronic commerce draws on technologies such as mobile
commerce, electronic funds transfer, supply chain management,
Internet marketing, online transaction processing, electronic data
interchange (EDI), inventory management systems, and automated
data collection systems.
Modern electronic commerce typically uses the World Wide Web for
at least one part of the transaction's life cycle although it may also
use other technologies such as e-mail.

9. Types of E-commerce

There are 6 basic types of e-commerce:
Business-to-Business (B2B)
Business-to-Consumer (B2C)
Consumer-to-Consumer (C2C)
Consumer-to-Business (C2B)
Business-to-Administration (B2A)
Consumer-to-Administration (C2A)

10. Types of E-commerce
10
Business-to-Business (B2B): Encompasses all electronic transactions of
goods or services conducted ​​between companies. Producers and
traditional commerce wholesalers typically operate with this type of
electronic commerce.
Business-to-Consumer(B2C): Distinguished by the establishment of
electronic business relationships between businesses and final
consumers. It corresponds to the retail section of e-commerce, where
traditional retail trade normally operates.
Consumer-to-Consumer (C2C): Encompasses all electronic transactions
of goods or services conducted ​​between consumers. Generally, these
transactions are conducted through a third party, which provides the
online platform where the transactions are actually carried out.

11. Types of E-commerce
11
Consumer-to-Business (C2B): In C2B there is a complete reversal of the traditional sense of
exchanging goods. This type of e-commerce is very common in crowdsourcing based
projects. A large number of individuals make their services or products available for
purchase for companies seeking precisely these types of services or products. Examples of
such practices are the sites where designers present several proposals for a company logo
and where only one of them is selected and effectively purchased. Another platform that is
very common in this type of commerce are the markets that sell royalty-free photographs,
images, media and design elements, such as iStockphoto.
Business-to-Administration (B2A): This part of e-commerce encompasses all transactions
conducted online between companies and public administration. This is an area that
involves a large amount and a variety of services, particularly in areas such as fiscal, social
security, employment, legal documents and registers, etc. These types of services have
increased considerably in recent years with investments made in e-government.

12. Types of E-commerce

Consumer-to-Administration (C2A): Encompasses all
electronic transactions conducted between individuals and
public administration. Examples of applications include:
Education – disseminating information, distance learning,
etc.
Social Security – through the distribution of information,
making payments, etc.
Taxes – filing tax returns, payments, etc.
Health – appointments, information about illnesses, payment
of health services, etc.

15. Advantages of E-commerce
15
The main advantage of e-commerce is its ability to reach a global market, without necessarily
implying a large financial investment. The limits of this type of commerce are not defined
geographically, which allows consumers to make a global choice, obtain the necessary
information and compare offers from all potential suppliers, regardless of their locations.
By allowing direct interaction with the final consumer, e-commerce shortens the product
distribution chain, sometimes even eliminating it completely. This way, a direct channel between
the producer or service provider and the final user is created, enabling them to offer products
and services that suit the individual preferences of the target market.
E-commerce allows suppliers to be closer to their customers, resulting in increased productivity
and competitiveness for companies; as a result, the consumer is benefited with an improvement
in quality service, resulting in greater proximity, as well as a more efficient pre and post-sales
support. With these new forms of electronic commerce, consumers now have virtual stores that
are open 24 hours a day.
Cost reduction is another very important advantage normally associated with electronic
commerce. The more trivial a particular business process is, the greater the likelihood of its
success, resulting in a significant reduction of transaction costs and, of course, of the prices
charged to customer.

16. Disadvantages of E-commerce
16
The main disadvantages associated with e-commerce are the
following:
Strong dependence on information and communication technologies (ICT).
Lack of legislation that adequately regulates the new e-commerce
activities, both nationally and internationally.
Market culture is averse to electronic commerce (customers cannot touch
or try the products).
The users’ loss of privacy, the loss of regions’ and countries’ cultural and
economic identity.
Insecurity in the conduct of online business transactions.
