Networking Devices
A. Switches
Purpose: Switches connect the individual computers in the cafe, and enables connected devices to share information and talk to each other.
Specifications: Gigabit Ethernet switches with 16 ports.
Placement: Each switch connect to host devices, for example computers and printers.
B. Router
Purpose: Router connects the network to the internet, and managing traffic between subnet by forwarding data packets to their intended IP addresses.
Specifications: High-speed router with firewall capabilities for security.
Placement: Router is connected to switches and modem.
C. Modem
Purpose: Modem work as a bridge between the local network and the internet service provider (ISP) and transforms digital information from your computer into analog signals that can transmit over wires (and vice versa).
Placement: Modem is connected to the router and ISP.
D. Wireless Access Point
Purpose: Allows wireless-capable devices to connect to a wired network
Placement: Wireless access point is connected to switch in each subnet.
Topology

Communication Media
A. Wired Cat-7 RJ45 Ethernet Cables (Guided Media)
Specifications: Made of 4 shielded twisted pair (STP) of copper wires with two RJ45 connectors on each end.
Advantages: It is reliable and high-speed connections with low latency. Also, the additional shielding and improved quality in twisting of the wires provides better protection from crosstalk, noise, and interference that can degrade the signal quality.
Placement: Wired Ethernet Cable is connected from each computer to their respective switches, and from switches to the router.
B. Wireless Access Points (Unguided Media)
Purpose: It provides internet connection for customers with mobile devices, like smartphones and laptops.
Placement: Wireless Access Points is strategically around the cafe for optimal coverage.
