Its purpose was to help all citizens regardless of their income level. The Internet was originally cited as a model for this superhighway; however, with the explosion of the World Wide Web, the Internet became the information superhighway”.

: a telecommunications infrastructure or system (as of television, telephony, or computer networks) used for widespread and usually rapid access to information especially : internet. — called also infobahn, information highway.

A popular buzzword to describe the Internet, bulletin board services, online services, and other services that enable people to obtain information from telecommunications networks. In the U.S., there is currently a national debate about how to shape and control these avenues of information.

Information Superhighway is a high-speed global communications network that can carry data, voice, video and other services around the world using technology such as the satellite, optical fibre and cellular telecommunications. 5.

eCommerce security is the guidelines that ensure safe transaction through the internet. It consists of protocols that safeguard people who engage in online selling and buying of goods and services. You need to gain your customers’ trust by putting in place eCommerce security basics.

E-commerce (electronic commerce) is the buying and selling of goods and services, or the transmitting of funds or data, over an electronic network, primarily the internet. These business transactions occur either as business-to-business (B2B), business-to-consumer (B2C), consumer-to-consumer or consumer-to-business.

Different Types of E-Commerce

• What Is E-Commerce?
• Business-to-Business (B2B)
• Business-to-Consumer (B2C)
• Mobile Commerce (M-Commerce)
• Facebook Commerce (F-Commerce)
• Customer-to-Customer (C2C)
• Customer-to-Business (C2B)
• Business-to-Administration (B2A)

Four Traditional Types of Ecommerce Business Models

• B2C – Business to consumer. B2C businesses sell to their end-user.
• B2B – Business to business. In a B2B business model, a business sells its product or service to another business.
• C2B – Consumer to business.
• C2C – Consumer to consumer.

Personal Area Networks (PAN) Local Area Networks (LAN) Metropolitan Area Networks (MAN) Wide Area Networks (WAN)

LAN to WAN – Connecting one of the Ethernet ports (LAN ports) of the main router to the Internet port (WAN port) of the secondary router. This connection makes it easier to identify which router the computers and other devices in the network are connected to since they will have different LAN IP segments.

LAN is a computer network that covers a small geographic area, like a home, office, or group of buildings, while WAN is a computer network that covers a broader area. The speed of LAN is high whereas the speed of WAN is slower than LAN. LAN offers more fault tolerance but WAN offers less fault tolerance in WAN.

Sometimes it will be labeled WAN. This port is intended to connect your router to the modem and the outside world from there. The LAN ports are designed for connecting to local devices. Plug one Ethernet cable into your modem and the other end into your router’s WAN port.

WAN stands for Wide Area Network and this is the network that connects your router to your service provider. The WAN port usually connects to a DSL modem, cable modem or fibre media converter. LAN stands for Local Area Network and this is the network that connects the devices within your home/business to the router.

Computers should not be connected to a router’s WAN port, as this would prevent data from entering or exiting the network. Instead, a computer should be connected to a router’s local area network (LAN) port, as these ports are specifically intended to handle local network traffic.

There are currently two main speed standards for LAN ports: Ethernet (also called Fast Ethernet,) which caps at 100 megabits per second (or about 13 megabytes per second), and Gigabit Ethernet, which caps at 1 gigabit per second (or about 150 MBps).

Serial cables

Wide area network (WAN) A WAN can cover country, continent or even a whole world. Internet connection is an example of WAN. Other examples of WAN are mobile broadband connections such as 3G, 4G etc.

A wide area network (WAN) is a telecommunications network that extends over a large geographic area for the primary purpose of computer networking. Wide area networks are often established with leased telecommunication circuits. The Internet may be considered a WAN.

The WAN port in a WiFi router is essentially connecting you to the real “internet”. The cable coming out of modem, or if a PPPoE connection, a simple RJ45 ethernet cable are to be plugged in the WAN port. And then, you can access internet.

WANs are either point-to-point, involving a direct connection between two sites, or operate across packet-switched networks, in which data is transmitted in packets over shared circuits. Depending on the service, WANs can be used for almost any data sharing purpose for which LANs can be used.

WANs can be used to connect cities, states, or even countries. WANs are often used by larger corporations or organizations to facilitate the exchange of data, and in a wide variety of industries corporations with facilities at multiple locations have embraced WANs.

The best example of a Wide Area Network is th Internet itself. Other smaller examples of WANs are: A network of bank cash dispensers; A Company network with several branch offices geographically distant.

WANs provide dedicated traffic for your organization, and they are much more secure than the internet itself. Additionally, sending your information across the internet means that you have to share bandwidth with millions of other businesses rather than having your own dedicated bandwidth by using WAN.

The distinguishing features of WAN are

• WANs have a large capacity, connecting a large number of computers over a large area, and are inherently scalable.
• They facilitate the sharing of regional resources.
• They provide uplinks for connecting LANs and MANs to the Internet.

Advantages of a wide area network (WAN)

• Covers large geographical area:
• Centralized data:
• Get updated files and data:
• A lot of application to exchange messages:
• Sharing of software and resources:
• Global business:
• High bandwidth:
• Distribute workload and decrease travel charges:

Types of WAN technologies

• TCP/IP protocol suite. TCP/IP is a protocol suite of foundational communication protocols used to interconnect network devices on today’s Internet and other computer/device networks.
• Router.
• Overlay network.
• Packet over SONET/SDH (PoS)
• Multiprotocol Label Switching (MPLS)
• ATM.
• Frame Relay.
