PDAs Short History
PDA or personal digital assistant (PDA) is a mobile device that functions as a personal information manager. It act as an electronic organizer or day planner that is portable, easy to use and capable of sharing information with your pC. It is not a replacement of your PC but an extension.
In 1986, the first PDA was released by Psion the Organizer II and was followed in 1991 by Psion's Series which began to resemble the more familiar PDA style. They included small keyboards for input, a small display, and basic features such as an alarm clock, calendar, telephone pad and calculator. Support for specialized software such as games and spreadsheets was also included.
The term 'PDA' was first used on January 7, 1992 by Apple Computer CEO John Sculley at the Consumer Electronics Show in Las Vegas, Nevada, referring to the Apple Newton. Some of the Newton's innovations have become standard PDA features, including a pressure-sensitive display with stylus, handwriting recognition capabilities, an infrared port and an expansion slot. However, the Newton MessagePad was too big, expensive and complicated, and its handwriting recognition program was poor. Apple discontinued the Newton in 1998.
Palm Computing in 1996 introduced the original PalmPilot. It has it's own operating systems, fit in a shirt pocket and synchonized with consumers' PCs. The PalmPilot ran for weeks on AAA batteries, was easy to use, and could store thousands of contacts, appointments and notes. Part of its small size was due to the lack of a keyboard. Users used a stylus and the Graffiti language to input data.
In November 1996, Microsoft released Windows CE, its first operating system for mobile devices.Some manufacturers adopted it for what was dubbed the Handheld PC -- the first Windows-based competitor for the PalmPilot.
Today, almost all PDAs are smartphones
. Over 150 million smartphones are sold each year, while "stand-alone" PDAs without phone functionality sell only about 3 million units per year.

Network Switch Confusion
A network switch is a device that connects different network segments together transparently. A network switch port is the location on the switch where devices connect to the switch. The devices connected to a network switch port may be computers, video game systems or even other network switches. Switches are common in large networks, such as in an office building or school. They are also found in households with high-speed Internet, but in this case, they are typically built into a multi-function router.
The term ‘switch’ is a broad catch-all for a wide range of computer network technologies. Even so, network hubs, home routers and network bridges are more commonly called switches than other devices. Each of these devices accomplishes a similar job from a switching standpoint, but is often capable of performing additional tasks outside of switching.
The design of each of these devices centers on its wired ports. These ports appear as rectangular openings that are slightly larger than a phone cord. Depending on the type of device, there may only be a handful of these ports or there may be several dozen. Often, these devices have a single port called an uplink or wide area network (WAN) port, but the rest are switch ports.
