Question

12 what is a key feature of peer - to - peer networks (p2p)?
centralized management of resources
high - speed data transfer rates
complex setup procedures
direct connection between computers without a central server
13 what is the worlds largest network?
wide area network (wan)
metropolitan area network (man)
the internet
local area network (lan)
14 what is the main purpose of network security?
increasing individual computer speed
enhancing graphics capabilities
reducing the need for computer maintenance
preventing unauthorized access to the network
15 what is a strong password policy?
using the same password for all accounts
writing passwords down for easy access
avoiding the use of special characters
using a mix of characters and changing regularly

Explanation:

1. In a Peer - to - Peer (P2P) network, computers can communicate directly without relying on a central server. It is decentralized. Centralized management is not a feature, high - speed data transfer is not its defining feature, and setup is often relatively simple.
2. The Internet is the world's largest network, connecting millions of smaller networks globally. WAN, MAN, and LAN are different types of networks with smaller scopes compared to the Internet.
3. The main purpose of network security is to prevent unauthorized access to the network to protect data and resources. It has little to do with individual computer speed, graphics capabilities, or computer maintenance.
4. A strong password policy involves using a mix of characters (letters, numbers, special characters) and changing passwords regularly to enhance security. Using the same password for all accounts, writing passwords down, and avoiding special characters are weak password practices.

Answer:

1. Direct connection between computers without a central server
2. The Internet
3. Preventing unauthorized access to the network
4. Using a mix of characters and changing regularly
