What are the basics of computer networking?
Computer networking connects devices so they can share data, internet access, and services using wired or wireless connections.
What is the difference between a router, switch, and modem?
A modem connects to your internet provider, a router directs traffic between networks, and a switch connects devices within a local network.
How do I set up a secure home network?
Use WPA3 or WPA2 encryption, create a strong Wi-Fi password, change default router credentials, and keep router firmware updated.
What is an IP address and why is it important?
An IP address identifies a device on a network, allowing it to send and receive data from other devices and internet services.
What is DNS and how does it work?
DNS translates domain names, such as example.com, into IP addresses that computers use to locate websites and services.
How do HTTP, HTTPS, and TLS differ?
HTTP transfers web data, HTTPS is HTTP protected by encryption, and TLS is the security protocol that provides that encryption.
What topics are covered in CompTIA Network+ N10-009 training?
Network+ N10-009 training commonly covers network hardware, IP addressing, routing, switching, wireless networking, security, troubleshooting, and network operations.
