Looking at its general structure, the OSI model stands out as a concept that comprehends how communication in computer networks takes place. The OSI Model, known as Open Systems Interconnection, has a structure developed by the International Organization Standardization (ISO) and divides network communication processes into seven separate layers. When looking at this layered structure, it highlights certain standards, especially to ensure that network devices and software can work in harmony. The main task of the OSI model is to better understand network communication and to solve problems more easily. Today, there are many different areas where the OSI model is used.       <\/p>\n\n<h2 class=\"wp-block-heading\"><strong>What are the 7 Layers of the OSI Model?<\/strong><\/h2>\n\n<p>Although there are many different types of networks in the network sector today, the OSI model is used especially for these networks to establish their interactions. The OSI model, which consists of different layers, is widely preferred in many different areas of use. Generally, the OSI model, which has many relative and used today in terms of usage area and type, offers a comfortable use with data units.  <\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Physical Layer: <\/strong>The Physical Layer is one of the layers among the uses of the OSI model, which specifically emphasizes how data transmission takes place in the physical environment. It is used efficiently in areas such as electrical signals, cable types, connectors and voltage levels. The most efficient examples of these situations are Ethernet cables and fiber optic cables. As a data unit, bits are used in physical layers.   <\/li>\n<\/ul>\n\n<ul class=\"wp-block-list\">\n<li><strong>Data Link Layer: <\/strong>The Data Link Layer stands out as the layer that enables data transmission between many different devices on the same network and performs operations such as framing and editing for error-free data transmission. It is known for using physical addressing.   <\/li>\n<\/ul>\n\n<ul class=\"wp-block-list\">\n<li><strong>Network Layer: <\/strong>The network layer, which is preferred for routing data packets between different networks, is also known for performing forwarding operations. This special layer, which ensures that the data reaches the right destination by using protocols such as IP addressing and routing, stands out for efficient use in routers and with IP addresses. <\/li>\n<\/ul>\n\n<ul class=\"wp-block-list\">\n<li><strong>Session Layer: <\/strong>Another type of layer among the layers in terms of OSI model usage is the session layer. The session layer manages the establishment, maintenance and termination of the session between two devices. On the other hand, the session layer is preferred because it ensures the synchronization of data exchange and the security of the session.    <\/li>\n<\/ul>\n\n<ul class=\"wp-block-list\">\n<li><strong>Transport Layer: <\/strong>The transport layer is used when a connection needs to be established to ensure end-to-end communication and reliable transmission of data. The transport layer, which manages operations such as data flow control, error control and data integrity, is among the most widely used and most preferred layer types. <\/li>\n<\/ul>\n\n<ul class=\"wp-block-list\">\n<li><strong>Presentation Layer: <\/strong>The presentation layer is the layer that determines how data is formatted and presented before or after it is transmitted or received in the network environment. You can easily perform operations such as encryption, transformation and compression of data at these layers. The presentation layer, which uses direct data as the data unit, stands out with its secure and fast connection.  <\/li>\n<\/ul>\n\n<ul class=\"wp-block-list\">\n<li><strong>Application Layer: <\/strong>A layer with which users interact directly, the application layer provides application software with easy access to network services. The application layer, which provides the end-user services required for data transmission, is preferred because it is used in web browsers and e-mail systems. <\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Although there are many different types of networks used in computers, there are certain types&#8230;<\/p>\n","protected":false},"author":8,"featured_media":14884,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"inline_featured_image":false,"footnotes":""},"categories":[44],"tags":[],"class_list":{"0":"post-16317","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-uncategorized"},"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v23.9 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>What is the OSI Model? 7 Layer Structure in Network Communication - Global IT<\/title>\n<meta name=\"description\" content=\"The OSI model deals with network communication in 7 layers.
