- 2. Network Architecture Overview A computer network is a collection of devices that are interconnected to communicate and share resources. The architecture of a network refers to the design and organization of its components and how they interact with each other. There are various types of network architectures, including client-server, peer-to-peer, and hybrid. Each architecture has its own advantages and disadvantages, and the choice of architecture depends on the specific needs and requirements of the network. In general, a network architecture consists of hardware components such as routers, switches, and servers, as well as software components such as protocols and applications. These components work together to ensure efficient and reliable communication and resource sharing between devices on the network.

Encryption We use encryption to secure our data transmissions and protect sensitive information. Access Control We implement access control measures to ensure that only authorized users can access our network resources.

- 5. Bandwidth Management Effective bandwidth management is essential for optimizing network performance. This involves prioritizing traffic and allocating bandwidth to critical applications and services. Network administrators can use Quality of Service (QoS) protocols to ensure that high-priority traffic is given priority over low-priority traffic. Additionally, bandwidth throttling can be used to limit the amount of bandwidth allocated to non-critical applications. Load Balancing Load balancing involves distributing network traffic across multiple servers or network devices to prevent any single device from becoming overloaded. This helps to improve network performance by ensuring that resources are utilized efficiently. Load balancing can be implemented using hardware or software solutions, and can be configured to distribute traffic based on various criteria such as server availability, traffic type, and geographic location.

- 7. Network Monitoring and Maintenance Network Monitoring Network monitoring involves the continuous observation and analysis of network traffic to identify issues and ensure optimal performance. This can be done through various tools and techniques, such as packet sniffers, network analyzers, and flow- based monitoring. Network Maintenance Network maintenance involves the regular upkeep and updates of network hardware and software components to ensure optimal performance and security. This can include tasks such as software patches and updates, firmware upgrades, and hardware replacements or repairs.
