Websites are created for being used by desktop computers and laptops. The problem with a mobile accessible website is that if you create a website for a computer, the resolution will be suited for that computer size or near about. If you access the website through your mobile device. It wont be very accessible due to the screen resolution differences.

In conclusion the internet and network are different and they work together to provide user with the data individual might need from World Wide Web.
Most often m-commerce is understood as mobile e-commerce M-commerce is supposed to enable us to buy everything from anywhere over the Internet without the use of a PC. Internet access and Web browsing is assumed to be the key to extending m-commerce to customers (Harter, 2000). In many ways, m-commerce is the continuation of e-commerce with the palm handheld, wireless laptops and a new generation of Web-enabled digital phones already on the market (Keen, 2001). 2.0 Merits of E-business over traditional
Other routers contain additional multi-hop routing capabilities to forward packets to reach their destinations. WMNs are used as wireless backbones in campuses, enterprises and by ISPs to provide last-mile Internet access to users. In order to communicate with other mesh routers, routers should use common channels. However, traditional wireless routers are equipped with single wireless network interface card (NIC), therefore whole network uses only one channel. Furthermore, in multi-hop settings throughput decreases significantly with increasing number of nodes and hops.
Paired devices can share voice, data, music, photos, videos, and other information wirelessly (Bluetooth Technology 101: Fast Facts). It is a combination of both hardware inside a device and software used to create the connections. WiFi or Wireless LANs define a short-range wireless network typically used in an office or home setting that allows several users to access the network resources. IEEE 802.11 sets the standard for wireless LAN equipment and speeds and products under this standard are marketed as the WiFi brand (Certification Partners, 2012). When speeds are mentioned, it is typically in reference to the top speeds available but generally, lower speeds are the expectation.
DHCP is the networking protocol in which connections are created, each individual device connected is assignment a unique IP address. DHCP5 is the dynamic host configuration protocol. This protocol is used to assign IP addresses to computer within a network, and IP addresses are stored on the server waiting to be assigned to a computer that connect to it. Primarily DHCP is for larger networks, nevertheless the speed of DHCP results in the popularity of such networking protocol.

Once a connection is established between the user and the network, the user will be prompted with a login screen and password if it is a fee-based type network. Though there’re also free-based network connections as well in some areas. Wi-Fi networking around the world is creating hot spots in cities where anyone with a laptop can wirelessly plug into the internet.
Ad-Hoc (Peer to Peer) consists of a number of computers each equipped with a wireless networking interface card. Each computer can communicate to other wireless enabled computers. They can share files and printers, but may not be able access wired LAN resources unless one computer acts as a bridge to connect to a wired LAN. Access points (base stations) can be hardware based or software based. The hardware based access point is a separate component connected to a wired Ethernet network and or server via an interface card.
So basically when you’re on the internet it’s a big sharing place on one network and you can connect to thousands of different devices and you can be on one network instead of having multiple networks. A (LAN) is a local network so it’s not worldwide more personal so you would find (LAN) in homes, school, and small offices. Only let down about having (LAN) network you are limit geographical areas. A (WLAN) is a wireless LAN that’s means its Wi-Fi you don’t need to have devices any hardwires connected so it’s just like Bluetooth on your phone it’s pretty much in open space that you can connect too. (PAN) is a personal network area these is the common one at home there use for communication among computer communicating information giving devices.
Voice over Internet Protocol (VoIP) is a technology that allows a person to make real-time voice calls using a broadband Internet connection (RJ-45) instead of on an analog phone line (RJ-11). Some businesses offer VoIP services that only allow people to call others using the same software or service, but other companies allow a person to call anyone who has a telephone number. These VoIP phone calls can include any made to local, long distance, mobile and international phone numbers. While some VoIP services only work over your computer or a specially installed VoIP phone, other services allow you to use a traditional phone connected to a VoIP adapter that is easily connected to a switch or router. VoIP technology has recently become available for use on cell phones, but this requires the use of large amounts of data on the network.
