# Network Diagram A network diagram is a visual representation of your computer or telecommunications networks. It focuses on components and connections within a network. These connections form between linked devices, data, and interaction points called nodes. A network diagram typically includes: - **Computers:** Represented as rectangles or icons. - **Network Devices:** Switches, routers, hubs, firewalls, etc., represented as specific symbols. - **Connections:** Lines connecting devices, representing cables or wireless connections. - **Labels:** Descriptions identifying each device and connection type. ## Network Structure The image depicts a basic network setup: - **Client:** A computer accessing resources on the network. - **Server:** A computer providing services or resources. - **Keystone Jack:** A port on a wall plate for connecting cables. - **Patch Panel:** A device for organizing and terminating cables. - **Switch:** Connects multiple devices on a network. - **Router:** Connects different networks, including the internet. - **WAP (Wireless Access Point):** Allows devices to connect wirelessly to the network. **Cable connections:** - **Straight Through LAN Cable:** Connects devices directly to the network. - **RJ45 Connector:** A common type used to connect cables to network devices. ## Network Devices Network devices, also known as network equipment or computer networking devices, are electronic devices that are required for communication and interaction between devices on a computer network. They mediate data transmission in a computer network. Some of the most common network devices are: - **Hubs:** Connect all network devices together on an internal network. - **Switches:** Learn the physical addresses of devices connected to them and store physical MAC addresses. Direct data packets to the intended destination port and reduce traffic. - **Routers:** Routes or forwards data to another network based on their IP address. Acts as the gateway of a network, connecting different networks. - **Modems:** Convert digital signals to analog signals and vice versa, allowing computers to communicate over phone lines or other analog networks. - **Wireless Access Points (WAPs):** Allow devices to connect wirelessly to a wired network. - **Repeaters:** Increase the strength of wireless signals, extending the reach of a wireless network. ## Network Diagram * **Computer:** A computer connected to the network. * **6 Port Switch:** Connects up to six devices. * **ISP (Internet Service Provider):** Provides internet connection to the network. * **Cloud:** Represents the internet or external resources. ## Important Concepts * **IP Address:** A unique identifier for a device on a network, allowing for communication between devices. * **Subnet Mask:** Helps to divide an IP address into two parts, identifying the host (computer) and the network it belongs to. * **MAC Address:** A unique physical address burned into a network card. ## Wireless Networks Wireless networks use electromagnetic waves to transmit data. They are convenient and provide flexibility, but offer less security and rely heavily on signal strength. ## Choosing the Right Network When choosing a network type, consider the following: - **Data transfer requirements:** How much bandwidth do you need? - **Distance:** How far apart are devices you want to connect? - **Security:** How important is it to keep data secure? - **Cost:** What is the budget for equipment installation and maintenance? ## Advantages and Disadvantages of Fiber Optic and Copper Cables **Fiber Optic Cables** - **Advantages:** High bandwidth, long distances, good security, immune to EMI and RFI, fireproof, less susceptible to interference. - **Disadvantages:** Expensive, requires specialized equipment, installation can be more complex. **Copper Cables:** - **Advantages:** Low cost, readily available, easier to install, more flexible. - **Disadvantages:** Limited bandwidth, shorter distances, susceptible to EMI and RFI, prone to interference. **Note:** The document provided does not provide any information regarding the specific type of cabling in the network structure image. Therefore, we cannot give a definitive answer about the type of cabling used.
