1. What are the main architectural components of a LAN? (Minimum word count: 60) The first characteristic in the LAN architecture is the physical arrangement of the network. This is how the nodes connect. The topology of an LAN is the design pattern of interconnections between the computers and network sectors. The second component is the method of access for the nodes. Specifically‚ how the nodes connect to the transmission medium. A network interface card is a device that permits computers

17.1 ARCHITECTURAL ACOUSTICS Architectural acoustics may be defined as the design of spaces‚ structures‚ and mechanical/electrical systems to meet hearing needs. With proper design efforts‚ wanted sounds can be heard properly and unwanted sounds (noise) can be attenuated or masked to the point where they do not cause annoyance. Achieving good acoustics‚ however‚ has become increasingly frequency is sometimes referred to using a term borrowed from music—pitch. The higher a sound’s frequency
