A chair fitted with a black slipcover. A slipcover (also called loose cover) is a fitted protective cover that may be slipped off and on a piece of upholstered furniture. Slipcovers are usually made of cloth. Slipcovers slip on and off, they come fresh, and may be removed for seasonal change, cleaning, moving, or storage.
SLIP can be used on RS-232 serial ports and supports asynchronous links. A more common protocol is PPP (Point-to-Point Protocol) because it is faster and more reliable and supports functions that SLIP does not, such as error detection, dynamic assignment of IP addresses and data compression. In general, Internet service providers offer only one protocol although some support both protocols.
