Words to know

Compression
Making a file smaller, usually by lowering quality a little, so it uploads and sends faster.
IPv4 / IPv6
Two versions of IP addresses. IPv4 looks like 192.168.1.1 (running out); IPv6 is the newer, much longer kind like 2001:db8::1.
Average (mean) / median
Average = add everything and divide by how many. Median = the middle value when sorted; it is not pulled by extreme values.
