XI TKJ _ TEKNOLOGI JARINGAN BERBASIS LUAS Pemahaman Dasar Jaringan Berbasis Luas (WAN) Part 1
Summary
TLDRThis educational video script delves into the concept of Wide Area Networks (WAN), a technology that spans vast geographical areas to connect local area networks (LAN) and enable communication across different locations. It covers the history of WAN development, starting from the 1940s, and its evolution with the advent of the internet. The script discusses the uses of WAN, including operating over large geographical boundaries and providing both full-time and on-demand connections. It also explains three types of WAN connections: Packet Switching, Circuit Switching, and dedicated connections, each with its advantages and disadvantages. The video aims to clarify the differences between LAN and WAN, focusing on characteristics, benefits, and limitations.
Takeaways
- 🌐 The script discusses the concept of Wide Area Network (WAN), which is a computer network that covers a broad area and can connect networks over long distances.
- 🏢 WANs are used to connect Local Area Networks (LANs) across different locations, enabling communication between computers in various places.
- 📈 The development of WANs began in the 1940s with research aimed at shared computer usage, evolving into the internet and global connectivity.
- 🔍 The script differentiates between LAN and WAN, highlighting their characteristics, advantages, and disadvantages.
- 🚀 The use of WAN technology allows for the operation of networks with wide geographical boundaries and provides access through low-speed serial interfaces.
- 🌐 WANs provide full-time (always on) or part-time (on-demand) connections, facilitating communication between separate devices across a global area.
- 💡 The rapid advancement of computer networking technology during the 1960s and 1970s led to the creation of LANs and the larger WANs, enabling information exchange between computers.
- 🔌 The script explains three types of WAN connections: Packet Switching, Circuit Switching, and Dedicated (Point-to-Point) connections, each with its own advantages and disadvantages.
- 💼 Packet Switching is beneficial for cost-saving by sharing bandwidth among users but is not suitable for continuous data transfer.
- 🔗 Dedicated connections offer a continuous and always-on service to a single customer but can be expensive.
- 📞 Circuit Switching requires a setup before data transmission, providing temporary but continuous connections, similar to a telephone call, and also tends to be costly.
Q & A
What is the main focus of the first meeting on the subject of Wide Area Network (WAN) technology?
-The main focus of the first meeting is to discuss the material from Chapter 1, which is to understand the technology of Wide Area Networks.
What is the definition of a Wide Area Network (WAN)?
-A Wide Area Network (WAN) is a computer network that covers a broad area and can connect networks from a distance.
What are the 7 topics that will be discussed in the first chapter about WAN technology?
-The 7 topics to be discussed are the development of WAN, the use of WAN technology, the classification of WAN connections, the advantages and disadvantages of WAN, the hierarchy of WAN, and the tools and components of WAN.
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.
