Is Internet and World Wide Web the same?
The world wide web, or web for short, are the pages you see when you’re at a device and you’re online. But the internet is the network of connected computers that the web works on, as well as what emails and files travel across. The world wide web contains the things you see on the roads like houses and shops.
How are the Internet and the World Wide Web Similar How are they different?
To start, the internet is bigger. Much bigger. It’s actually a network of networks, connecting millions of computers around the globe. The World Wide Web uses Hypertext Transfer Protocol (HTTP) – a language used to transmit data – to access information that lives on different networks.
What is www how it is related to Internet?
The World Wide Web (WWW), commonly known as the Web, is an information system where documents and other web resources are identified by Uniform Resource Locators (URLs, such as https://example.com/ ), which may be interlinked by hyperlinks, and are accessible over the Internet.
What is the similarity of network and Internet?
Both use cables and fibers INTERNET TELEPHON NETWORK It is packet-switched network. The Internet is simply a network of networks, which means there is no such thing as a standalone computer on a network. Internet is wide network of computers and is open for all. Answer: The two networks are similar in the fact that a.
How is the star network different from a mesh network?
In star topology, the nodes are connected to the central hub or router. In mesh topology, the nodes are connected to each other completely via dedicated link. The cost of Star topology is less. The cost of Mesh topology is expensive.
Why is a mesh network better than a star network?
Star Topology due to its simple structure is less complex as compared to Mesh Topology. On other hand due to more complexity in nodes arrangement Mesh Topology is considered as more complex. Star Topology is cost efficient as compared to Mesh Topology.
What is the benefit of a mesh network over a star network?
Better performance than other setups as there are very few data collisions and data goes straight to the central device so all devices can transmit data all at once.
What is a disadvantage of a star network?
Requires more cable than a linear bus . If the connecting network device (network switch) fails, nodes attached are disabled and can’t participate in network communication. More expensive than linear bus topology due to the value of the connecting devices (network switches)
Where would a star network be used?
Star networks are used in timesharing systems with the central node being the timesharing “host” computer.
What is star topology with diagram?
A star topology is a topology for a Local Area Network (LAN) in which all nodes are individually connected to a central connection point, like a hub or a switch. A star takes more cable than e.g. a bus, but the benefit is that if a cable fails, only one node will be brought down.
How is Star network connected?
A star network is a local area network (LAN) in which all nodes (workstations or other devices) are directly connected to a common central computer. Every workstation is indirectly connected to every other through the central computer. In some star networks, the central computer can also operate as a workstation.
What is a mesh network and the advantages and disadvantages?
Conclusion: In summary advantages of Wireless Mesh network are improvement in fault tolerance without the need of centralized management and so on. The disadvantages of Wireless Mesh are difficult to install and manage in addition to costly end devices for subscribers/users of the network.
Which topology is highest reliability?
A mesh network is a local network topology in which the infrastructure nodes connect directly, dynamically and non-hierarchically to as many other nodes as possible and cooperate with one another to efficiently route data from/to clients. Of all these, Star Topology is highly reliable one.
How many types of signal generate from Internet modem?
three types
What are the three types of modems?
These are cable, DSL, Fiber and dial-up modems.
Why modem is both input and output device?
A modem is considered an input/output device because a modem sends and receives data at the same time. For example, whenever you are surfing, you send a web-page request that its info out, or output. A printer is both an Input and output device or a I/O.
