Explains based on rich pictures.\u003cbr\u003e We created and inserted 104 figures, which help you easily understand the overall network.\u003cbr\u003e - We tried to explain the basic principles of networks.\u003cbr\u003e It goes without saying that the basic principles are important for any technology. \u003cbr\u003eUnderstanding the basic principles will enable you to understand the applied technologies that extend them, and furthermore, will enable you to develop the ability to solve problems in real-world situations.\u003cbr\u003e Covers the entire spectrum of networks. It covers everything from fundamental principles like the OSI-7 layer model, IP, MAC, ARP, ICMP, TCP, UDP, L2 switches, L3 routers, local area networks, and wide area networks, to applied technologies like virtual private networks, proxies, routers, hacking, and firewalls.\u003cbr\u003e - Explained by dividing it into OSI-7 layers. OSI-7 layers are an important concept for understanding networks.\u003cbr\u003e This is explained by dividing it into layers so that the concepts and technologies of each layer can be clearly understood.\u003cbr\u003e\u003cbr\u003e When you first start studying networks, you often only get an abstract and vague understanding of them, but you often skip over the underlying fundamental principles. \u003cbr\u003eIf you start working as a software developer in that state, you will encounter many network-related problems.\u003cbr\u003e Whenever that happens, rather than finding the cause of the problem and solving it, we tend to solve it by tinkering with various things.\u003cbr\u003e It is difficult to find the cause of the problem because the basic principles are not understood.\u003cbr\u003e This type of approach is a bad problem-solving method that only provides temporary relief and does not improve your skills in the long run.\u003cbr\u003e\u003cbr\u003e I started working as a network firewall developer, and this process gave me a solid understanding of the fundamental principles of networks. I gained a code-level understanding of how TCP and UDP work in the kernel, and I learned how network devices like L2 switches and L3 routers work. \u003cbr\u003eFurthermore, we have come to understand clearly how the huge network system called the Internet is structured and operates.\u003cbr\u003e\u003cbr\u003e I am currently a software developer with 20 years of experience.\u003cbr\u003e They say that understanding network principles is a great help in software development.\u003cbr\u003e Just as when a problem occurs during software development, you can quickly identify the cause by using several tools.\u003cbr\u003e I was able to build an internal network that suited my company and effectively implemented network security.\u003cbr\u003e The author's extensive practical experience and practical know-how are all contained in 104 illustrations and helpful explanations. \u003cbr\u003e\n\n\u003c\/div\u003e\n\u003cdiv\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\u003ccenter\u003e\u003ctable\u003e\u003ctr\u003e\u003ctd style=\"height:10px\"\u003e\u003c\/td\u003e\u003c\/tr\u003e\u003c\/table\u003e\u003c\/center\u003e\n\n\u003ccenter\u003e\u003ctable\u003e\u003ctr\u003e\u003ctd style=\"height:10px\"\u003e\u003c\/td\u003e\u003c\/tr\u003e\u003c\/table\u003e\u003c\/center\u003e\n\n\u003cdiv style=\"width:95%;padding-top:20px;padding-bottom:20px\"\u003e\n\n\u003cdiv style=\"text-align:left;font-size:16px;font-weight:bold;padding-bottom:20px\"\u003e GOODS SPECIFICS \u003c\/div\u003e\n\n\u003cdiv style=\"text-align:left;font-size:14px;line-height:1.6em;\"\u003e\n\n\u003cdiv style=\"width:100%;margin-bottom:5px;line-height:1.6em;font-size:14px\"\u003e - \u003cstrong\u003eDate of issue:\u003c\/strong\u003e August 30, 2025\u003c\/div\u003e\n\n\u003cdiv style=\"width:100%;margin-bottom:5px;line-height:1.6em;font-size:14px\"\u003e - \u003cstrong\u003ePage count, weight, size:\u003c\/strong\u003e 170 pages | 391g | 190*257*7mm\u003c\/div\u003e\n\n\u003cdiv style=\"width:100%;margin-bottom:5px;line-height:1.6em;font-size:14px\"\u003e - \u003cstrong\u003eISBN13:\u003c\/strong\u003e 9791193059623\u003c\/div\u003e\n\n\u003cdiv style=\"width:100%;margin-bottom:5px;line-height:1.6em;font-size:14px\"\u003e - \u003cstrong\u003eISBN10:\u003c\/strong\u003e 1193059623 \u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\u003ccenter\u003e\n\n\u003ccenter\u003e\u003ctable\u003e\u003ctr\u003e\u003ctd style=\"height:10px\"\u003e\u003c\/td\u003e\u003c\/tr\u003e\u003c\/table\u003e\u003c\/center\u003e\n\n\u003ccenter\u003e\u003ctable\u003e\u003ctr\u003e\u003ctd style=\"height:10px\"\u003e\u003c\/td\u003e\u003c\/tr\u003e\u003c\/table\u003e\u003c\/center\u003e\n\n\u003cspan\u003e\u003c\/span\u003e\n\n\u003c\/center\u003e\n\n\n\u003c\/center\u003e","brand":"LIBRAIRIE COREENNE","offers":[{"title":"Default Title","offer_id":43893387001898,"sku":"139951","price":24.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0683\/2750\/5962\/files\/3372df228e46407324556fd5d76779c6.jpg?v=1765399694","url":"https:\/\/librairie.coreenne.fr\/en\/products\/139951","provider":"LIBRAIRIE COREENNE","version":"1.0","type":"link"}
