PDA & PPC Comparison

Filed under: ppc — khwooo @ 2:31 am

這是關於PDA和PPC的比較,之前常搞不清楚這兩種東西差在哪裡,以為PDA=PPC,其實PDA的領域很廣,其中也包含了PPC,詳細如下:

PDA 是 Personal digital assistant 的簡寫,泛指一切便於攜帶的數位個人助理,這裡面包括有個人助理功能的手機、筆記型電腦和Pocket PC,以下取自wikipedia

Personal digital assistants (PDAs) are handheld computers that were originally designed as personal organizers, but became much more versatile over the years. PDAs are also known as pocket computers or palmtop computers. PDAs have many uses: calculation, use as a clock and calendar, playing computer games, accessing the Internet, sending and receiving E-mails, video recording, typewriting and word processing, use as an address book, making and writing on spreadsheets, use as a radio or stereo, and Global Positioning System (GPS). Newer PDAs also have both color screens and audio capabilities, enabling them to be used as mobile phones (smartphones), web browsers, or portable media players. Many PDAs can access the Internet, intranets or extranets via Wi-Fi, or Wireless Wide-Area Networks (WWANs). One of the most significant PDA characteristic is the presence of a touch screen.

PPCPocket PC的簡寫,PPC是指安裝了特定版本Windows系統的掌上型電腦(PC),雖然PPC有可能運行Linux or BSD,不過現在依然是以Windows Mobile為主流,以下取自wikipedia

A Pocket PC, abbreviated P/PC or PPC, is a specification for a handheld-sized computer (Personal digital assistant) that runs a specific version of the Windows CE operating system. It may have the capability to run an alternative operating system like NetBSD or Linux. It has many of the capabilities of modern desktop PCs.

Currently there are thousands of applications for handhelds adhering to the Microsoft Pocket PC specification, many of which are freeware. Some of these devices also include mobile phone features. Microsoft compliant Pocket PCs can also be used with many other add-ons like GPS receivers, barcode readers, RFID readers, and cameras.

另外, MicrosoftPocket PC 的定義:

the Pocket PC is “a handheld device that enables users to store and retrieve e-mail, contacts, appointments, tasks, play multimedia files, games, exchange text messages with Windows Live Messenger (MSN Messenger), browse the Web, and more.(src: microsoft buyersguide)

根據M$社的習慣,說不定他們註冊了Pocket PC這個詞勒…
整個覺得豁然開朗,Wikipedia真是好東西。
