Networking

In this, networks help in communication and data exchange through an interesting way to troubleshoot network connectivity issues and optimize network performance.

The main elements include firewalls, routers, switches, cables, and computing devices like servers and computers. They help in the transmission and communication of data.

IPv4 employs 32-bit addresses, whereas IPv6 employs 128-bit addresses, and hence there are more devices that can be accessed using IPv6 over the internet.

I examine the physical links, inspect the IP configuration, analyze network traffic, and employ diagnostic utilities such as ping or tracert to determine the cause of the issue.

DNS (Domain Name System) converts domain names to IP addresses so that websites can be accessed using memorable names rather than numerical IP addresses.

A router forwards data packets from one network to another, making sure that data is delivered to the right destination by finding the best route for transmission.

I would use firewalls, encryption, robust authentication, periodic software updates, and monitoring of the network to block unauthorized access and secure data.

A subnet mask separates an IP address into network and host components, enabling devices to determine if an IP address is on the same network.

A VLAN (Virtual Local Area Network) logically groups network devices together, irrespective of physical location for enhancing network performance and security.

I regularly read networking blogs, attend webinars, and take online courses to stay informed about the latest trends, tools, and technologies in networking.
