Term	Definition
PCMCIA	PCMCIA (Personal Computer Memory Card International Association) is the name of the
	group that produced the specification for the credit card-sized plug-in boards for laptop
	computers. The cards used to be called PCMCIA cards, but as this was rather
	unpronounceable, these cards are now termed PC cards. An example of a PC card is a credit
	card-sized modem. See PCMCIA.
Pixel	A pixel (Picture Element) is a part of your screen. Your screen is made up of thousands of
	pixels, enabling you to see colours and pictures on it. The more pixels, the higher the
	resolution and the better the image quality.
Port replicator	An additional device that you can connect to your notebook. The port replicator contains
	ports that enable you to connect additional peripherals (such as a printer or a monitor) to
	your VAIO. A port replicator is similar to a docking station, but does not include additional
	slots for adding expansion boards or storage devices.
Processor	The processor is the brains of the computer; it processes the instructions of your system’s
	programs. The processor is also known as the CPU or microprocessor and can be found on
	the motherboard (see this word) of your computer.
Product recovery CD-ROM	The product recovery CD-ROMs include the application recovery CD-ROM and the system
	recovery CD-ROM(s)
PS/2	A type of mouse or keyboard port. The plug that connects to the port always contains 6 pins.
PSTN	PSTN (Public Switched Telephone Network) refers to the plain old telephone service, the
	national telecommunication networks implementing voice transmission by using analog
	signals.
RAM	Short for Random Access Memory, the memory used to run programs and store data in
	current use. RAM is the fastest kind of memory to read from and write to. Information stored
	in RAM is lost when you turn off the computer. The higher the RAM capacity, the faster your
	current data can be processed.
