The essentials of networking include understanding how devices connect and communicate, knowing network topologies, protocols like TCP/IP, configuring hardware like routers and switches, and ensuring security and troubleshooting.

CompTIA N10-007 is the exam code for the Network+ certification that tests foundational networking skills. Yes, it was officially retired in June 2021 and replaced by the newer N10-008 & N10-009 exam.

Yes, you can take the Network+ certification without having the A+ certification first. A+ is recommended for foundational IT knowledge but is not mandatory.

Generally, yes. CCNA (Cisco Certified Network Associate) covers more in-depth networking concepts and Cisco-specific technologies, making it more challenging than the vendor-neutral Network+ certification.
