Firewall

A network node that prevents traffic from one segment of a

 

network from crossing over into another. Firewalls are used

 

to protect internal systems from unauthorized external

 

access.

Flash Memory

A memory feature or component which calls your mobile

 

device to save information without power.

GPRS

General Packet Radio Service represents the first

 

implementation of packet switching within GSM, which is

 

essentially a circuit switched technology. Rather than

 

sending a continuous stream of data over a permanent

 

connection, packet switching only utilizes the network

 

when there is data to be sent. Using GPRS will enable users

 

to send and receive data at speeds up to 115kbits/sec

GSM

Global System for Mobile Communications. Digital

 

cellphone system used through Europe based on TDMA

 

(Time Division Multiple Access - a digital communication

 

technology). Data transfer rates of 9.6 kbps.

Hot Sync Mode

A method by which a mobile device is connected by

 

cradle/bay or cable to a desktop/notebook computer in order

 

to perform synchronizations. Synchronizations update data

 

or information from an external source to the mobile device.

Infrastructure

The combined components needed to operate a wireless

 

network including sites, switching and transmission

 

equipment.

Interface

Method or piece of equipment for interconnecting units or

 

systems which may not be directly compatible.

Kbps

A measurement of bandwidth in the United States.

Land-Line

A connection that uses land-based networks or ‘wires’.

Last Connect

The last time an active connection (session) was made or

 

synchronization was performed.

Latency

The time taken for data packets to pass through GPRS,

 

normally measured as a round-trip time.

m-commerce

Mobile Commerce. Business transactions conducted with

 

online mobile devices.

Mbps

Mega (million) bits per second. Measurement of

 

transmission speed or bandwidth.

MHz

Megahertz. One million cycles per second (hertz).

 

Measurement of electromagnetic energy and transmission

 

speed (such as CPU's internal clock).

Middleware

An intermediate software component located on the wired

 

network between the wireless appliance and the application

 

or data residing on the wired network.

Mobility

Ability to continually move from one location to another.

Offline mode

A disconnected state that does not have an active

 

connection and is not receiving data or information in real-

 

time.

Optimization

Application software used to improve the performance of

Middleware

the basic bearer (transmission provider that provides service

 

between user-network interfaces) service.

PalmOS®

The operating system for a mobile device. There are several

 

device manufacturers that use this operating system.

PCMCIA

Personal Computer Memory Card International Association. A

 

standardized technology used to develop an expansion for portable

 

devices (i.e. notebooks) in paging credit card-sized support

 

wireless connectivity.

OS Devices specifications

Palm OS devices, integral to the evolution of mobile computing, emerged in the late 1990s, characterized by their unique operating system and innovative features. The Palm OS, developed by Palm, Inc., was specifically designed for handheld devices and PDAs (Personal Digital Assistants), establishing a foundation that would influence many subsequent mobile operating systems.

One of the key features of Palm OS devices was their user-friendly interface. The system employed a simple, menu-driven navigation scheme that utilized a stylus for interaction on a touchscreen display. This touchscreen capability was pioneering at the time, allowing users to effortlessly navigate through applications and settings. The devices often featured a compact design, with physical buttons for shortcuts, enhancing usability.

Palm OS devices were renowned for their productivity applications. The Calendar, Contacts, and To-Do List applications helped users organize their tasks and schedules efficiently. Additionally, the inclusion of third-party applications through the Palm Software Development Kit (SDK) allowed for the expansion of functionality, giving rise to a diverse ecosystem of apps that catered to various user needs, from finance to entertainment.

Another notable characteristic of Palm OS was its synchronization capabilities. Users could connect their devices to desktop computers via USB or serial connections to sync data, ensuring that their information remained updated across devices. The introduction of the Palm HotSync technology simplified this process, allowing users to transfer contacts, emails, and documents with ease.

In terms of hardware, Palm OS devices typically boasted small screens, ranging from 160x160 pixels to larger 320x320 pixel displays in later models. Most devices were powered by ARM processors, known for their efficient performance and low power consumption, enabling longer battery life — a crucial factor for mobile users.

Connectivity options also advanced with Palm OS devices. While early models primarily relied on infrared communication, later iterations introduced features such as Bluetooth and Wi-Fi, facilitating easier data transfer and internet access. This evolution allowed users to stay connected and productive while on the go.

Overall, the legacy of Palm OS devices lies in their emphasis on usability, portability, and integration with personal productivity tools. Their influence can still be seen in modern smartphones and mobile applications, marking them as pivotal players in the development of portable technology.
