You are an IT consultant for a small, medium, and large business. The small business has 25 users. The medium business has 50 users. The large business has 100 users. You’ve been tasked with creating a document which will provide guidance in designing their new networks. This will be a universal document used to develop new networks as businesses open or expand. information on transmission mediums, protocols, and standards that may be applicable for the corresponding business size. This information will be used for any future expansion of each network and will serve as a network planning document to keep each network consistent moving forward. the “New Network Guidance” Excel spreadsheet. a 1- to 2-page Microsoft Word document each of these businesses can use for guidance when designing new networks. Include information on transmission mediums, protocols, and standards. Format the completed Word document following APA guidelines. both the Microsoft Word document and Excel spreadsheet using the Assignment Files tab.

Title: Guidance for Designing Networks for Small, Medium, and Large Businesses

Introduction:
Network design is a critical aspect of any business, as it lays the foundation for efficient communication and data exchange. This document aims to provide guidance for designing new networks for small, medium, and large businesses. It will outline the recommended transmission mediums, protocols, and standards that should be considered during the network planning process. The information provided will ensure consistency and scalability for future network expansions. This document will be a valuable resource for businesses when designing and implementing their networks.

Transmission Mediums:
Selecting the appropriate transmission medium is crucial for network performance and reliability. The following mediums are recommended based on the size of the business:

1. Small Business (25 users):
For small businesses, Ethernet over twisted-pair cabling (such as Cat5e or Cat6) is a cost-effective and reliable option. It supports data transfer rates up to 1 Gigabit per second (Gbps) and provides sufficient bandwidth for the number of users in this business category. Additionally, wireless access points can be integrated into the network to provide wireless connectivity.

2. Medium Business (50 users):
Medium-sized businesses require higher bandwidth to accommodate increased user demands. Fiber-optic cabling is recommended as the transmission medium in this scenario. It offers higher data transfer rates and superior performance over longer distances compared to twisted-pair cabling. This ensures that network speeds remain optimal for all users. Wireless access points should also be deployed strategically to ensure wireless coverage throughout the premises.

3. Large Business (100 users):
For large businesses, a combination of fiber-optic cabling and high-capacity Ethernet over twisted-pair cabling is suitable. Fiber-optic cabling should be used for core network infrastructure, while twisted-pair cabling can be deployed to connect end-user devices within the premises. This approach allows for efficient communication across departments and provides high-speed connectivity to all users. Wireless access points should be strategically placed to ensure comprehensive coverage across the entire facility.

Protocols and Standards:
The choice of protocols and standards impacts network compatibility, security, and interoperability. Here are some recommendations for each business size:

1. Small Business:
To ensure compatibility and ease of deployment, the Transmission Control Protocol/Internet Protocol (TCP/IP) suite is recommended. TCP/IP is widely used and supported by most network devices, operating systems, and applications. For security, the use of the Secure Socket Layer (SSL) or Transport Layer Security (TLS) protocol is advised when transferring sensitive data.

2. Medium Business:
In addition to TCP/IP, medium-sized businesses should consider implementing the Virtual Local Area Network (VLAN) protocol. VLANs allow for the segmentation of network traffic, enhancing security and performance by isolating different user groups or departments. The use of the Dynamic Host Configuration Protocol (DHCP) can simplify IP address management.

3. Large Business:
Large businesses should consider implementing more advanced protocols and standards, such as Border Gateway Protocol (BGP) for routing between autonomous systems or Open Shortest Path First (OSPF) for internal routing within the enterprise. Network Access Control (NAC) protocols should also be considered to ensure secure access to the network.

Conclusion:
This document provides guidance for designing new networks for small, medium, and large businesses. The recommended transmission mediums, protocols, and standards discussed will ensure efficient and scalable network infrastructures. By following this guidance, businesses can design and implement networks that meet their specific needs while allowing for future expansion.
