NetCLI vs Computer Networking Basics

NetCLI is a free, hands-on Cisco network simulator for CCNA on your iPhone, iPad or Mac. Build a network, type real Cisco IOS commands on routers and switches, and see the result in the topology. Practice subnetting, IPv6, Wi-Fi and troubleshooting anywhere. Practice familiar Cisco IOS commands from Packet Tracer in offline labs, wherever you study. Made for students preparing for the CCNA 200-301 exam, networking classes and anyone who wants to understand how networks really work. A NEW BROKEN NETWORK EVERY DAY • Daily troubleshooting: every day someone calls with a network problem – a port that's down, a wrong mask, two PCs on one IP, Wi-Fi that won't connect. Find the fault in the IOS terminal and prove the fix with your own ping • One free job every day, with a different fault, network and caller • Stamp your work orders through the week, and try a day again for a better stamp BUILD AND CONFIGURE YOUR OWN NETWORK • My Lab: add routers, switches and PCs, connect them and configure each device from its own terminal, with notes for each lab. The free lab supports up to 6 devices and one named save • Cisco IOS command line: user, privileged and global configuration mode, show commands, ? help and IOS-style error messages • PC command prompt that works like the one in Packet Tracer • Ping and packet trace to test your network • Wi-Fi: set up an access point with an SSID and a WPA2 key, then get a laptop online • Starter topologies and guided exercises when you don't know where to begin LEARN STEP BY STEP • Guided lessons from networking basics to CCNA topics • Readiness Check: a free, timed set of CCNA-style questions to see where you stand • Quiz: multiple-choice networking questions at different difficulty levels SUBNETTING AND IP ADDRESSING • Subnetting trainer with four difficulty levels: get a random IP and prefix, then find the network, broadcast, host range and usable hosts • Subnet practice for VLSM and CIDR, with an IPv6 example NETWORK REFERENCE TOOLS • Command library: look up Cisco IOS commands for VLANs, OSPF routing, ACLs, DHCP, NAT/PAT, IPv6, SSH and diagnostics, and open a lab scenario to try them • Config Explainer: paste a Cisco configuration and get a plain-English explanation of every line • Packet Tracer guides: step-by-step walkthroughs for common lab scenarios • Troubleshooting playbooks: work layer by layer through the OSI model with the right show commands • Interactive OSI model and network map THE BLOOM PROTOCOL: AN IT MYSTERY It's 2003.
