Read the three scenarios below and answer the questions that follow each scenario:

1. You are the network administrator for a new company that has 10 users and plans to add 5 more within a year. The files need to be accessed by all 10 users, and each user must have different security rights. What kind of network would you install? How would the pieces and components of this network relate to each other? Define each component.

2. You are the network administrator for a company that has a peer-to-peer network. How would the pieces and components of this network relate to each other? Define all the components of this type of network.

3. You are the administrator of a client-server environment. What kind of network would you install? How would the pieces and components of this network relate to each other? Define each component of a typical client/server environment.

Designing and implementing appropriate network architecture is crucial for the operational efficiency, security, and scalability of an organization. The choice among peer-to-peer, client-server, or other network types hinges on various factors including the number of users, security requirements, data sharing needs, and future growth plans. This paper explores the three scenarios provided, analyzing the suitable network types, their components, and how these components interrelate to meet organizational needs.

Scenario 1: Small to Medium Business with Growing User Base

The first scenario involves a nascent company with 10 users initially, planning to expand to 15 within a year. Each user requires direct access to shared files, with specific security rights assigned. The ideal network configuration for this setup is a small local area network (LAN) with either client-server or peer-to-peer architecture.

For organizations with fewer users and a need for distinct security rights, a client-server network is typically recommended. Such a network involves a dedicated server that manages security, resource allocation, and data sharing. The server acts as a central node that authenticates users, controls access rights, and ensures data integrity. In this context, the server would host shared files and manage user permissions, providing a secure environment where each user’s security rights are enforced effectively.

The components of this client-server network include:

• Server: The central computer managing resources, security, and data storage.
• Client Machines: Employee computers connected to the server, accessing shared resources.
• Network Devices: Switches and routers linking the server and clients, managing data flow.
• Security Components: Firewalls and access control lists (ACLs) to restrict and monitor access based on user rights.
• Network Protocols: TCP/IP, which facilitates communication between devices.

This configuration ensures that data access is controlled, secure, and scalable to accommodate future growth. The components are interconnected in a way that allows seamless data sharing while maintaining security and efficiency.

Scenario 2: Peer-to-Peer Network

In the second scenario, the company employs a peer-to-peer (P2P) network. This type of network connects multiple systems directly, allowing each device to act as both a client and a server. P2P networks are common in small organizations or for specific tasks where ease of setup and low cost are priorities.

The primary components in a P2P network include:

• Peer Devices: All computers in the network that share resources directly with each other without centralized management.
• Shared Resources: Files, printers, or other devices directly accessible by peers.
• Network Infrastructure: Switches or hubs that connect the peers.
• Security Mechanisms: User authentication and permissions to control who can access specific shared resources.

The relationship among components in a P2P network is decentralized, with each peer managing its own resources and security. This setup is flexible and cost-effective for small groups but becomes inefficient and insecure at larger scales due to the lack of centralized control.

Scenario 3: Client-Server Environment

The third scenario involves the deployment of a client-server network environment. This setup is suitable for organizations with larger user bases, complex resource management needs, and stringent security policies.

The core components of a client-server network are:

• Server: The backbone that handles data storage, processing, security, and resource management. Examples include dedicated file servers, database servers, or application servers.
• Clients: Workstations or computers used by end-users to access server-hosted resources and services.
• Network Devices: Switches, routers, and firewalls that facilitate secure and efficient communication between servers and clients.
• Network Protocols: Protocols like TCP/IP, HTTP, FTP, which enable reliable communication and data transfer.
• Security Infrastructure: Firewalls, intrusion detection systems (IDS), and access controls to protect sensitive data and systems.

This architecture allows centralized management of resources and security, simplifies maintenance, and enhances scalability. It also supports sophisticated user authentication mechanisms, data backup, and resource allocation strategies.

Comparative Analysis

Choosing the right network depends on factors such as organizational size, security requirements, and scalability. While peer-to-peer networks are suitable for small, simple setups, client-server networks provide a more robust and secure environment for larger operations. Mixed environments can also be tailored to specific organizational needs, leveraging the advantages of each approach.

Conclusion

In conclusion, understanding the components and relationships within different network architectures is essential for designing efficient, secure, and scalable systems. For a startup with a small user base and specific security needs, a client-server setup offers centralized control and security. Peer-to-peer networks serve well for small, informal groups. Larger organizations benefit from a well-structured client-server architecture, providing better management, security, and scalability. Proper planning and understanding of these elements ensure that organizational technology infrastructure aligns with business goals and growth plans.
