Other common acronyms refer to network connections between computers. An example is LAN, which stands for "local area network." This is a network in which computers within close proximity to each other are connected to the same router. An ISP, or "internet service provider," is the company responsible for maintaining a personal or business Internet connection for a fee.

TLA is a kind of meta-acronym, standing for "three-letter acronym" and referring to other computer acronyms, such as CPU, ISP and USB that have three letters. Another common three-letter acronym is SSD, which stands for "solid state drive." As a storage device without moving parts, this is contrasted with the HDD ("hard disk drive"), a more common storage device with spinning disks inside.
