The network is primarily needed for exchanging files, accessing and managing beta websites on their web server, and connecting to the Internet. The firm hires many freelancers who come into the office on an ad-hoc basis and it does not have a lot of money to spend on infrastructure. What type of network will you recommend?
Short Answer:

I would recommend a mixed wired and wireless network. The wired LAN would connect the web servers and primary workstations and connect via cable service to the Internet. Freelancers could connect wirelessly via access points.
question
38) What are the two types of signals used to communicate a message in a network and how are they different? What device converts one type to the other type?
Short Answer:
answer
The two ways to communicate a message in a network are analog signals and digital signals. An analog signal is represented by a continuous waveform that passes through a communications medium and is used for voice communication. Examples include the telephone handset and other types of speakers that generate analog sound. On the other hand, digital signals are binary waveforms (not continuous) that communicate information as strings of two discrete states: one bit or zero bits (often depicted as strings of zeroes and ones). Computers use these types of signals and use modems to convert digital signals to analog signals.
