What is the historical development of WAN?
-The historical development of WAN began in the 1940s in America with research on shared computer usage, and it continued to evolve until the introduction of the internet, leading to the formation of a global network known as WAN.
What is the difference between LAN and WAN?
-The difference between LAN (Local Area Network) and WAN (Wide Area Network) lies in the geographical scope they cover. LAN is limited to a smaller area such as a building or office, while WAN covers a broader area like cities or countries.
What are the uses of WAN technology?
-WAN technology is used to operate networks with a wide geographical boundary, allowing access through serial interfaces operating at low speeds, and providing full-time or part-time connections.
How does WAN technology enable communication between computers?
-WAN technology enables communication between computers by connecting local area networks (LANs), allowing users in different locations to communicate with each other.
What are the three types of WAN connection classifications?
-The three types of WAN connection classifications are Packet Switching, Circuit Switching, and Dedicated Connection (also known as point-to-point or clear slime).
What is Packet Switching and how does it benefit users?
-Packet Switching is a communication path based on data transmission in packets, allowing data from various devices on the network to use the same communication channels simultaneously. It benefits users by allowing them to share bandwidth and potentially save on costs.
What is the main disadvantage of Packet Switching?
-The main disadvantage of Packet Switching is that it works well only if the data transfer is not continuous or is required only occasionally.
How does Circuit Switching differ from Packet Switching?
-Circuit Switching is a connection path used with dial-up networks where a setup is required before data can be passed. It provides a continuous connection but only temporarily and usually requires a higher cost.

🌐 Introduction to Wide Area Networks (WAN)

This paragraph introduces the topic of Wide Area Networks (WAN) in the context of technology education. It explains that a WAN is a computer network that covers a broad area, allowing for inter-network connections over long distances. The paragraph outlines the seven main topics to be covered in the first chapter, including the development of WAN, its uses, technology, classification of connections, advantages and disadvantages, hierarchy, and tools and components. The focus of this video is on the development and uses of WAN, highlighting the transition from LAN to interconnected networks forming a global network. It also touches on the historical development of networks and the advent of the internet, leading to the formation of WANs. The paragraph concludes by inviting viewers to understand the differences between LAN and WAN, including their characteristics, advantages, and disadvantages.

🔌 Types of WAN Connections

The second paragraph delves into the types of connections used in WANs. It discusses three main types: Packet Switching, which is a communication path based on data transmission in packets, allowing for the sharing of bandwidth among users and cost savings but is not suitable for continuous data transfer; Circuit Switching, which is a temporary connection setup required before data transmission, similar to a telephone call, and is costly; and dedicated connections, which provide a continuous connection for a single customer at all times, offering flexibility but at a higher cost. The paragraph concludes by encouraging viewers to ask questions if they have any doubts about the material presented.

Keywords

💡WAN (Wide Area Network)

WAN stands for Wide Area Network, which is a computer network that spans a broad area and typically includes multiple local area networks (LANs). In the video, WAN is discussed as a network that can connect different cities or even countries, allowing for communication between different LANs. The script mentions that WANs are used to connect LANs, enabling users in different locations to communicate with each other.

💡LAN (Local Area Network)

LAN refers to a Local Area Network, which is a computer network that covers a small geographical area such as a home, school, or office building. The script contrasts LAN with WAN, highlighting that LANs are smaller in scope and are connected to form larger networks like WANs. LANs are the building blocks of WANs, allowing for localized communication within a confined area.

💡Broadband

Broadband is a term used to describe high-speed internet and data connections that have a large bandwidth and can carry more data than traditional dial-up connections. In the context of the video, broadband is mentioned as a key development in the evolution of WANs, signifying the move towards faster and more capable networks that can support a variety of data-intensive applications.

💡Packet Switching

Packet Switching is a method of data transmission that breaks data into packets and sends them through a network. Each packet can take different paths to reach its destination, which can improve efficiency and reduce congestion. The video script describes Packet Switching as a type of connection in WANs, where data from various devices on the network can be sent through the same communication channels simultaneously, allowing for efficient use of bandwidth.

💡Circuit Switching

Circuit Switching is a method of connection where a dedicated communication path is established between two points before any data is transmitted. This type of connection is used for dial-up networks and is characterized by a setup phase before data transfer. The video script mentions Circuit Switching as a type of connection in WANs, where a connection is set up temporarily, and it is typically more expensive due to the dedicated path required.

💡Point-to-Point Connection

A Point-to-Point Connection is a direct link between two endpoints, used for data transmission without the need for intermediate devices. This type of connection is also known as a dedicated connection. The script refers to this as a type of connection in WANs where a single customer is provided with a continuous connection at all times, which can be costly but ensures constant availability.

💡Full-Time Connection

A Full-Time Connection, also known as 'Always On,' refers to a network connection that is active and available at all times, without the need for manual connection or reconnection. The video script discusses this as a benefit of WANs, where users can have a constant connection to the network, facilitating continuous communication and data transfer.

💡Part-Time Connection

A Part-Time Connection is a network connection that is established only when needed, as opposed to a full-time connection. This type of connection is typically used when continuous access is not required or when cost is a consideration. The script mentions this in relation to WANs, indicating that users can connect to the network on-demand, which can be more cost-effective for occasional use.

💡Serial Interface

A Serial Interface is a type of communication interface that transfers data one bit at a time, sequentially. It is used in WANs to connect devices over long distances. The video script refers to the use of serial interfaces in WANs, which allow for communication across vast geographical areas, enabling connectivity between different LANs.

💡Global Connectivity

Global Connectivity refers to the ability to connect and communicate across the world, regardless of geographical boundaries. The script highlights the role of WANs in providing global connectivity, allowing devices and users in different parts of the world to communicate and share data.
