1What is technology?
The art of improvement.
2Distinguish between peer to peer and client server networks?
Peer to peer is when no computer has more authority than another and is typically less than 15 devices. Client Server is where resources are managed by the network operating system via a centralized directory database. It's also typically on a larger scale.
3Identify types of applications and protocols used on a network.
- TCP (Transmission control protocol)
- IP (Internet Protocol)
- Web Server: HTTP
- Email Services: SMTP simlpe mail transfer protocol -
- DNS Service: Domain Name System (Helps clients find web servers over a network)
- FTP: FTP (File Transfer Protocol)
4What is topology? Describe the two types.
Physical topology refers to the hardware (physical hardware) and logical topology is the software controls that have access to the resources.
