반응형 전체 글30 What is a Gateway? - Gateway spoken by the network What I'm going to talk about this time is the gateway in the network. I often hear this, but there are many people who are confused about Gateway. In this session, we're going to give you an example of this gateway to make it easier to understand. 1. What is a Gateway? It's easy to think of it as a door to another network. For example, a network is a house, and if we want to go to the wrong hous.. 2024. 3. 26. Hub & Switch Operating Principles and Differences In this session, we will learn about the operating principles and differences between hubs and switches. Now, hubs are gone, but if you're a network engineer, you should know the operating principles of hubs and switches and the difference between them, right? 1. HUB - Equipment corresponding to 1 layer of OSI 7 Layer - Equipment used before the switch came out (hard to find now) - Ethernet CSMA.. 2024. 3. 25. Understand DHCP concepts and operating principles In this session, we will learn about the concept and operating principles of DHCP. 1. What is DHCP(Dynamic Host Configuration Protocol)? In wired and wireless IP environments, a DHCP server automatically allocates various network information such as a terminal's IP address, subnet mask, default gateway, IP address, DNS server IP address, and lease time to user terminals such as PCs. ※ Strengths .. 2024. 3. 25. NAT Address Translation, Concepts, and Principles of Operation In this session, we're going to talk about address translation NAT in the network. 1. NAT (Network Address Transloation) A system that converts one IP Address (public, external) into one or more IP Addresses for a specific purpose. The private IP band used internally must be changed to a public IP address in order to enable the Internet. Why? Private IP Address: Home-to-home address (Michael's m.. 2024. 3. 22. ARP Concepts and Principles of Operation This time, we're going to learn what ARP is and how it works. First of all, before I explain ARP, remember what the two addresses below mean. Logical Address = IP Address Physical Address = Local Address 1. ARP (Address Resolution Protocol) What is ARP? : Converting logical addresses to physical addresses - Order of operation when the terminal to communicate needs a physical address (Order in wh.. 2024. 3. 20. Spanning Tree - Operating Principles & Calculation Methods This time, we're going to talk about the Spanning Tree Protocol. Before doing STP, you need to know exactly why Looping occurs so that you can easily understand why this STP is used. If you don't know about Looping, I recommend you study Looping first and watch STP. 1. Spanning Tree Protocol : Maintaining a loop-free network (which logically blocks a particular port and does not forward frames t.. 2024. 3. 20. TCP & UDP Descriptions and Differences In this session, we will learn about the concepts, operating principles, and differences of TCP & UDP among the protocols used in the network. This part is also basic among the basics, so please understand it clearly. 1. TCP (Transmission Control Protocol) : Reliable protocols It is called a reliable protocol because the connection is established through 3-way handling before communication, and .. 2024. 3. 19. Cause and reason of Looping, and solution In this session, we will learn about looping that occurs in the network. Let's find out in detail why looping occurs, what problems occur when looping occurs, and how to solve looping. 1. What is looping? To study spanning tree, you must first understand Loop. It would be meaningful to learn the protocol to prevent looping when you know why it occurs. Then what is looping? Let's see why it happe.. 2024. 3. 18. 이전 1 2 3 4 다음 반응형
