What is the Internet?
The Internet is a global network of billions of computers and other electronic devices.
What is the World Wide Web?
is an information system that enables content sharing over the Internet through user-friendly ways meant to appeal to users beyond IT specialists and hobbyists.
What is the Wi-Fi
a wireless networking technology that uses radio waves to provide wireless high-speed Internet access.
What is browser?
A browser is an application program that provides a way to look at and interact with all the information on the World Wide Web.
What is QR-CODE
a machine-readable code consisting of an array of black and white squares, typically used for storing URLs or other information for reading by the camera on a smartphone.
What is a network protocol and what is its purpose?
A network protocol is the language or set of rules that computers use to communicate with each other. Protocols set standards for encoding and decoding data, guiding data to its destination, and reducing the effects of interference.
How is data usually transmitted over a communication channel?
Data transmitted over a communication channel usually takes the form of an electromagnetic signal such as waves of light, electricity, or sound.
What is network architecture and what are the two types mentioned in the text?
Network architecture is the way a network is organized. In a client-server network, a computer acts as a server and stores and distributes information to the other nodes or clients. In a peer-to-peer network, all the computers have the same capabilities - that is, they can share files and peripherals without requiring a separate server computer.
What is the cloud?
A cloud network is a Wide Area Network (WAN) that hosts users and resources and allows the two to communicate via cloud-based technologies.
How has the development of the Internet affected the life of mankind here?
The Internet has also changed the way we interact with our family, friends, and life partners. Now everyone is connected to everyone else in a simpler, more accessible, and more immediate way; we can conduct part of our personal relationships using our laptops, smart phones, and tablets.
What is the type of cloud deployment where an organization uses its own cloud for some services and a public cloud for others?
Hybrid cloud
What are the two general classifications of communication channels?
Channels are divided into two general classifications: wired and wireless.
How do wireless networks transmit data?
Wireless networks use electromagnetic waves, such as radio waves and microwaves, to transmit data.
How does cloud computing work? Tell in a few sentences.
Cloud computing is the delivery of computer system resources (e.g., servers, storage, databases, networking, software, analytics) over the internet.
Explain the difference between the following concepts.
The Internet and the Web
The World Wide Web, or simply “web,” is the term for the collection of web pages that you view when you are online on a computer or other device. On the other hand, the internet is the network of interconnected computers on which the web runs and the conduit through which emails and data pass
Wired LANs are more difficult to install, but they are cheaper, faster, and more reliable. Wireless networks let you move or roam, from one access point to another, but they are less secure and subject to interference.
What types of cables are used for wired channels?
Wired channels transport data through wires and cables including twisted pair wires used for telephone land lines, coaxial cables for cable television networks, and fiber-optic cables used for high-capacity trunk lines that provide main routes for telephone, cable, and Internet communications.

Decipher the abbreviations.
1. TCP
2. UDP
3. FTP
1. The Transmission Control Protocol (TCP) is one of the main protocols of the Internet protocol suite. It originated in the initial network implementation in which it complemented the Internet Protocol (IP).
2. In computer networking, the User Datagram Protocol (UDP) is one of the core communication protocols of the Internet protocol suite used to send messages (transported as datagrams in packets) to other hosts on an Internet Protocol (IP) network.
3. The File Transfer Protocol (FTP) is a standard communication protocol used for the transfer of computer files from a server to a client on a computer network. FTP is built on a client–server model architecture using separate control and data connections between the client and the server.
