Networking Discover the power of networking and how it facilitates communication and resource sharing among devices. Explore the various topologies and network devices that form the backbone of modern connectivity. by Gokhan Tekin Network Topologies 1 Star Network A common topology where devices are connected to a central hub, allowing for efficient communication and centralized management. 2 Ring Network A circular network where devices are connected in a loop, enabling data to travel in a sequential manner. 3 Mesh Network A network in which each device is connected to every other device, providing redundant paths for data transmission and enhancing reliability. Network Devices Hubs Switches Modem Routers Simple network Intelligent A device that Devices that devices that devices that connects your facilitate the receive data and analyze data network to the transfer of data broadcast it to packets and internet, packets between all connected selectively enabling different devices, forward them to communication networks, increasing the the appropriate with external ensuring collision destination, networks. efficient routing probability in optimizing and secure large networks. network communication. performance. Hubs vs Switches Hubs Switches Transmit data to all connected devices Forward data only to the intended recipient Increase network collisions Reduce network collisions Less efficient in large networks Optimize network performance in large networks Lower cost Higher cost Network Interface Card What is an NIC? A hardware component that enables a device to connect to a network, providing a unique identifier and facilitating data transmission. Types of NICs Wired NICs for Ethernet connections and wireless NICs for Wi-Fi connections. Importance of NIC Allows devices to communicate with the network and access shared resources, such as files and printers. Benefits of Networking 1 Efficient Communication 2 Resource Sharing Share information and collaborate Access files, printers, and other easily, improving productivity and network resources from any teamwork. connected device, enhancing flexibility and convenience. 3 Cost Savings 4 Scalability Centralize equipment and services, Expand your network to reducing the need for duplicate accommodate growing business resources and maximizing needs without major infrastructure efficiency. changes. Network Security 1 Firewalls Implement firewall solutions to Encryption 2 protect the network from unauthorized access and external threats. Secure data transmission using encryption techniques, preventing unauthorized interception and tampering. 3 Access Control Implement user authentication mechanisms and access restrictions to ensure only authorized users can access the network. Networking Challenges Cable Management Traffic Congestion Security Threats Organize and maintain a Manage network Continuously monitor and proper cable congestion during peak protect the network infrastructure to prevent usage periods to ensure against evolving cyber signal degradation and smooth and threats and troubleshooting uninterrupted data flow. vulnerabilities. difficulties.
