What is a megabyte?
The megabyte is one million bytes. A phone photo takes 2 to 5 MB and a minute of MP3 music about 1 MB. Email attachments are often limited to 20 or 25 MB.
What is a kilobyte?
The kilobyte, in the decimal SI sense, is 1,000 bytes. A short plain-text email weighs a few kB. Some software still uses KB to mean 1,024 bytes; the precise name for that is the kibibyte, KiB.
