Question 1

? What are the primary differences between Local Area Networks (LAN) and Wide Area Networks (WAN)

Accepted Answer

Local Area Networks (LAN) and Wide Area Networks (WAN) differ primarily in their geographical coverage and purpose.

LAN: A Local Area Network covers a small geographic area, such as a single building, office, or campus. It is typically used to connect computers and devices within a limited area to share resources like files, printers, and internet access. LANs are known for their high data transfer rates and low latency due to the proximity of connected devices.

WAN: A Wide Area Network spans a much larger geographical area, often encompassing cities, countries, or even continents. WANs connect multiple LANs to facilitate communication and resource sharing over long distances. They rely on telecommunications links like leased lines, satellite links, or the internet. WANs usually have lower data transfer rates and higher latency compared to LANs due to the greater distances involved.

Question 2

?What is the purpose of a Virtual Private Network (VPN), and how does it enhance network security

Accepted Answer

A Virtual Private Network (VPN) is designed to create a secure and encrypted connection over a less secure network, typically the internet.

Purpose: The primary purpose of a VPN is to ensure privacy and security for data transmitted between a user's device and the internet or another network. It allows remote users to securely access their organization's internal network from any location.

Enhancing Security: A VPN enhances network security in several ways:

Encryption: VPNs use encryption protocols to encode data, making it unreadable to unauthorized parties during transmission.
Anonymity: By masking the user's IP address, a VPN helps maintain anonymity online, making it difficult for hackers or third parties to trace online activities.
Secure Access: VPNs provide secure access to private networks and resources, preventing unauthorized access and protecting sensitive information from cyber threats.
Overall, VPNs are essential tools for maintaining data security and privacy in today's interconnected world.
