pace, a SAN will be all but necessary. Most SANs offer great disaster tolerance and scalability built in- something vital for keeping important company documents.
Other Types of Networks
Although you’d think we’ve just about covered it all, we can delve even deeper into network design. You may have heard of a WLAN, or a wireless local area network (which operates much like a LAN without cables). You might have also heard of a PAN- or a personal area network. These are usually used to describe small networks made between mobile devices such as phones. In the below example, you can see two devices connecting wirelessly- by Bluetooth, perhaps.
Although you can be as specific as you’d like, most networking exams only require you know the basics of LANs, WANs, MANs, and SANs. This may change in the future, so be sure to keep an open mind about the upcoming network designs. We did, after all, only start networking computers with simple LANs. Just years after, we have the many “AN”s that we just covered- and there’s no telling what we’ll have in the years to come.
