I'm starting CCNA 1 & 2 in September, so i'm doing some early studying and i'm reading about LANs and WANs.
LANs .....i get
WANs ...... i have a question. Do WANs use LANs to connect or are they using a completely different medium??
For example, a train from Edinburgh to London can pass through many stations. (WANs using LANs to connect LANs)
OR is it one main link that just connects cities, for example??
I've been searching the internet and can not find the answer in 'laymans terms' , there is so much terminology. Also, does anyone know of any beginners guide to networking, Cheers.
