Layer 4 is also responsible for choosing port numbers.\n\nSo why do we need port numbers? The example I give here is the postal service. To get post, you install a letterbox (at least here in the UK). This letterbox allows the postal service to access your home.\n\nNetwork applications work in the same way. If you want to communicate over a network, you must allow some means of access to your device. \n\nLet’s say we want to access a web server. We type in the web address (also known as a URL) of the site we want to visit.\n\nThe first thing the computer does it convert that URL to an IP address.\nThis is done by using DNS, but we will cover than in another video. For now, just know it coverts web addresses to IP addresses.\n\nThe computer then sends the request to the webserver. The server will then look at the destination port to find out which application to send this data to. It can do this because there is a standard that port numbers follow. \n\nWhen we made our web request, our computer knew we were trying to access a HTTP site. So it added the destination port number 80 to the TCP header.\n\nThe computer will also choose a randomly generated source port to receive reply’s on.\n\nSeveral port numbers are called well-known ports. These are common protocols that have been assigned port numbers.\nExamples of well-known port numbers are HTTP(80), HTTPS(443), SMTP (25).\n\n0 – 1023: Well-known port numbers. \n1024 – 49151: Registered ports that companies have registered IANA\n49152-65535: Dynamic ports\n\nResources:\nhttps://tools.ietf.org/html/rfc6335\nhttps://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xhtml\n\n#ccna #cisco #networking

MSP: Port là gì? Công dụng của Port 2022 New port number คือ
ดูข้อมูลที่เป็นประโยชน์เพิ่มเติมในหัวข้อ port number คือ
1. Port là gì?\nPort mạng là điểm cuối của quá trình giao tiếp trong hệ thống mạng máy tính, là giao thức bit 16 đứng đầu (chèn vào phần đầu header) của mỗi gói tin trong giao thức TCP, UDP hay còn gọi là cổng port, nơi quy định các tập dữ liệu riêng biệt\nPort là còn được định nghĩa một dạng thuật toán đã được định sẵn và mỗi máy tính cần phải có thì mới có thể nhận và gửi các gói tin đi được. Khi hoạt động Port cũng được quy đổi giống với số bit của bất kì một mã dữ liệu nào đó. Đơn giản thì đây giống như cánh cổng có quyền cho vào hay không với các dữ liệu muốn ra vào hệ thống máy tính của bạn. Khi có 1 địa chỉ IP, bạn sẽ xác định được một máy trong một mạng, nhưng nếu chúng chạy cùng nhiều dịch vụ khác nhau thì phải có cách để phân biệt được chúng và lúc này bạn cần đến Port.\nChẳng hạn, khi máy B muốn truy nhập dịch vụ web trên server A, trong gói tin gửi đi, IP đích sẽ là 210.245.126.14 và port đích sẽ là 80. Cùng lúc đó có máy C truy nhập đến dịch vụ DNS trên server A thì trong gói tin IP gửi đi, IP đích vẫn là 210.245.126.14 nhưng port đích sẽ là 53.\n\n2. Công dụng của port là gì?\nLà địa chỉ nhận diện tập tin, dữ liệu\nGiống như một người lính gác, số địa chỉ nhà ở, khi bạn đăng ký các loại port trên hệ thống máy tính của bạn sẽ giúp cho các tập tin được truy cập, được đưa vào đúng với địa chỉ port khớp với đầu bit tập tin đó.\nGiảm thiểu sự xâm nhập có hại tới máy tính\nPort có khả năng chống lại những xâm nhập có hại đến hệ thống máy tính của người dùng thông qua chức năng chọn lọc và cho phép các dữ liệu ra vào hệ thống máy tính. Nếu như phát hiện các tập tin xấu, nhiễm virus hay thông tin gây nhiễu thì port có khả năng loại bỏ ngay lập tức.\nCho phép chọn lọc tin\nPort sử dụng thuật toán của mình để quy định tập tin nào được phép đi vào máy và tập tin nào được phép xuất ra khỏi máy. Ngoài ra, Port còn sử dụng thao tác khớp cổng bit để người dùng kiểm soát và chọn lọc được đâu là tập tin an toàn và đâu là tập tin nguy hại và từ chối quyền truy cập của các tập tin gây hại đó.\n\n3. Đăng ký port phụ thuộc vào những yếu tố nào?\nKhi đăng ký port cần phụ thuộc vào những yếu tố quy định được cổng port khác nhau. Dưới đây là 2 tiêu chí dùng để xác định được mục đăng ký port mà bạn cần biết\n- Dựa vào thông số ổ cứng của máy\nKhi đăng ký 1 cổng port nhất định, trước hết cần phụ thuộc vào những thông số ổ cứng của máy. Những loại thông số ổ cứng của mỗi loại máy tính khác nhau sẽ quy định được tổng số port và loại port đăng ký\n- Dựa vào kho lưu trữ và khả năng chứa tập tin\nMỗi một cổng port sẽ hợp với những tập tin về dữ liệu cũng như số liệu về dung lượng và loại tập tin đó. Vì thế, khi đăng ký 1 cổng port, bạn cần phải dựa trên những thông số kho lưu trữ và khả năng chứa các loại tập tin trong máy tính. Từ đó, có thể dựa vào các thông số về các hạn chế mức tối đa và từng loại tập tin sẽ giúp định hình và quy định sử dụng loại port nào phù hợp nhất.\n\n4. Có những loại port thông dụng nào?\nỨng với các bit, hiện nay port có những loại cơ bản và phổ biến nào? Cùng điểm qua những loại port cơ bản nhất dưới đây\nMột số loại port thông dụng nhất hiện nay\n· 20 – TPC – File Transfer – FTP data\n· 21 – TPC – File Transfer – FTP control\n· 22 – TPC /UDP – SSH Remote Login Protocol\n· 23 – TPC – Telnet\n· 25 – TPC – Simple Mail Transfer Protocol (SMTP)\n· 38 – TPC – Route Access Protocol (RAP)\n· 42 – TPC -Host Name Server – Microsoft WINS\n· 45 – TPC – Message Processing Module (receive)\n· 46 – TPC -Message Processing Module (send)\n· 50 – TPC – Remote Mail Checking Protocol (RMCP)\n· 66 – TPC – Oracle SQLNET\n· 88-TPC -Trivial File Transfer Protocol (TFTP)

Every protocol in a computer network is having a unique ID which is also known as a port number.\nMost protocols in computer networks are having multiple port number which defines different task. for example, DHCP (Dynamic Host Configuration Protocol) is having two port number 67 and 68. where port number 67 is use for server and 68 are assigned to the client PC.\n\nEven POP3 and SMTP are having multiple port number. POP3 port number 110 are use to non encryption connection and port number 995 is use for encryption connection (SSL) on the other hand SMTP port number 25 is use for non encryption connection and port number 465 is use for encryption connection (SSL). This is the basic concept of port number in computer networking.\n\nBackground Music:\nPyres by Broken Elegance https://soundcloud.com/brokenelegance\nCreative Commons — Attribution 3.0 Unported— CC BY 3.0 \nhttp://creativecommons.org/licenses/b…\nMusic provided by Audio Library https://youtu.be/9xMg_xdpa7w\n\nVisit my Website: www.learnabhi.com\nSUBSCRIBE: www.youtube.com/technicaltechabhi\n\nSubscribe to my Hindi Channel: www.youtube.com/learnabhi\n\nFollow me on:\nFacebook: www.facebook.com/learnabhisocial\nInstagram: www.instagram.com/learnabhi\nTwitter: www.twitter.com/learnabhi\nDownload Networking Plus App: https://learnabhi.com/networking-plus

You’ll need to know its number to do that, but how are you supposed to find it? In this video we will explain what is port number, how to find it and why you may need it. \n\n***\n\nContents of the video:\n\n00:00 Intro\n00:00 What is port number and IP address\n00:00 Why should you know a port number\n00:00 How to find a port number\n\n***\n\nPort numbers are like extensions to your IP address. For example, your computer’s IP address is 53.125.105.18, while the file transfer protocol (FTP) port number is 20. Thus, the IP for an open FTP port would be 12.345.678.90:20. By seeing this address, the server will “understand” your request.\n\n***\n\nAbout NordVPN\n\nNordVPN is part of Nord Security, an online security company that aims to provide users with all the necessary online security tools. NordVPN is the world’s leading VPN provider protecting millions of internet users every day. We employ next-generation tech solutions to make sure our users enjoy online safety with peace of mind. Thanks to one of these advanced solutions — NordLynx, a brand new tunneling solution — NordVPN has become the fastest VPN on the planet, as confirmed by the latest speed tests. \n\nWhat is a VPN and how does it work? \nA virtual private network (VPN) encrypts online traffic and enhances privacy by changing the IP address and virtual location. It does so by routing all your internet traffic through a remote server. NordVPN offers over 5,200+ servers in 60 countries. It’s especially important to have VPN protection when you connect to public Wi-Fi. Public hotspots are inherently unsafe — cybercriminals can easily compromise them or set up fake hotspots to lure unsuspecting victims. You should always use NordVPN before connecting to public Wi-Fi.\n\nNordVPN is available on every major platform. You can use NordVPN on your laptop (Windows, macOS apps) or download it on your phone (Android, iOS apps).
