1. PC Card
PC Card is a removable device, approximately the size of a credit card, which is designed to plug into PCMCIA slot. It is standard, formulated by the Personal Computer Memory Card International Association (PCMCIA) for providing expansion capabilities to computers. The PCMCIA standard supports input-output devices, memory, fax/modems, SCSI, and networking products. The card fits into a notebook or laptop computer.

6. PDA/Pocket PC
Personal Digital Assistant (PDA) was initially introduced as a Personal Information Manager (PIM) device. PIM features include contact list, calendar, task list, e-mail, pocket word-processing application, pocket spreadsheet application, presentation viewer, and host of other applications that come in handy while on the move. PDA has a decent size LCD touch screen with a pen for handwriting recognition. It usually has a PC based synchronization utility that can be increased as required . Some PDAs also provide USB extension port that can be used to connect to external devices for extended features like external monitor, LCD Projector etc. Almost all PDAs have some digital camera capability as well.
Newer PDAs also pack network capability using WiFi, Bluetooth, etc. Due to network connectivity option, PDAs are having several applications in many domains such as medicine, teaching/training, data collection, sports, and Global Positioning System (GPS) based location and route finder. Several PDAs also provide GSM/GPRS service connectivity and, thus, can be used as phone for making and receiving cell phone calls, SMS, etc.
7. Page Impression

8. PCI Bus (Peripheral Component Interconnect Bus)
It is a fast local bus standard which provides fast data transfer within a PC and has superseded ISA. It is a specific design of local bus introduces by Intel. The PCI Bus permits upto to 10 expansion cards to be added to the PC.
9. PCMCIA (Personal Computer Memory Card International Association )
An expansion Bus designed or Laptops which allows modems and other devices to be connected to the PC.
10. Pentium II
The Pentium II processor was introduced by Intel in the middle of 1997. The speed of the Pentium II Processor when it was introduced was around 300 MHz. The Pentium II is basically the Pentium Pro incorporating MMX technology.
11. PERL (Practical Extraction and Report Language )

This allows pograms to be called in response to actions by the Web Client user i.e. something done by use on your PC on a particular Web Page. Almost any programming language can be used with PERL being the most popular .The Perl program site in between the Web Server and other software such as Databases.
