Basic Functions Of Handheld Computers
The handheld computer is similar to the desktop computer in many ways. For example, the handheld computer also has CPUs, memory, display chips, and operating systems. And just as personal computers can be divided into Mac and Windows camps, the handheld computer can also be divided into Palm and PPC camps, the main difference lies in the differences in operating systems. However, the functions of handheld computers are generally the same, mainly used for recording, document editing, playing games, playing multimedia, accessing the internet through built-in or external wireless network cards, and so on. And through many third-party software, you can also read e-books, image processing, external GPS card navigation, and so on.
Major Functions Of Handheld Computers
A "tape recorder" can record meeting content, record the words of interviewees, and leave behind every happy song and laughter in life. There are two recording formats for a "recorder", PCM and Mobile Voice, where the Mobile Voice format can record sound for several hours.
The "Pocket Dictionary" contains a bidirectional dictionary with a vocabulary of 150000 words, which can be used to search for Chinese meanings through English words or written in Chinese to find corresponding English expressions. If you want to memorize words, which start with A, as the words and phrases here are enough to help you reach a TOFEL or GRE vocabulary.
Global Clock Comparison Function
In the "Global Clock", you can find the time of over 100 countries and regions around the world, as well as the name of the airport where the region takes off, the time of sunrise and sunset, the phone area code, and the number of kilometers away from Beijing.
The handheld computer provides a variety of reminders, including LED flashing reminders, vibration reminders, voice reminders, and screen information display reminders. The sound reminder can also be set with different sounds. When setting reminders, you can choose how long to execute them in advance.
Leisure And Entertainment Functions
People can't work all the time. What can they do to relax their nerves when they are free? The handheld computer provides various leisure and entertainment functions to suit users with different personalities and hobbies.
Fax Management Function
As long as you have the fax software of the handheld computer, the fax function of Modem/Fax can be realized.
Users can not only listen to the sound from the handheld computer through the headphone jack, but also through the built-in speaker. The built-in speaker is located at the bottom of the handheld computer, and it can be used to listen to music or other audio files. The speaker is located on the back of the unit as well.
The microphone is one of the input devices for the handheld computer to collect sound sources. The built-in microphone of the handheld computer is relatively compact.
The handheld computer needs batteries to maintain normal operation. Lithium ion batteries or alkaline batteries can be used as their power supply. Few handheld computers use alkaline batteries as their power supply, such as ACER S10, PLAM M100, SONY PEG SL-10, etc. Most handheld computers use lithium ion batteries as their power supply. Handheld computer factories should choose high-quality batteries to ensure the quality of their products.
As a small portable digital device, the handheld computer has the advantages of convenient carrying and powerful functions, but its storage capacity is not large. From time to time, the files in the handheld computer need to be stored in the computer, which involves the problem of the connection mode with the computer. Data transmission interface is the interface between handheld computers and other devices. With this interface, handheld computers and other devices can achieve functions such as uploading, downloading, and data synchronization. The common data transmission interfaces for handheld computers include USB, serial, infrared, and Bluetooth interfaces.
The resolution of a display screen refers to its ability to parse images. The higher the resolution, the clearer the images displayed on the display screen. For example, early Palm models always used a monochrome 160 × 160 resolution, which represents 160 pixels in both horizontal and vertical directions on the display screen. Color display screens typically have a resolution of 240 × 320, 320 × 320 and more.
Bluetooth is a short distance wireless connection technology used to replace the use of cables or wires on certain electronic devices. The use of "Bluetooth" technology can effectively simplify the communication between mobile communication terminal devices such as handheld computers, laptops and mobile phones, and can also successfully simplify the communication between the above devices and the Internet, thus making the data transmission between these devices and the Internet more rapid and efficient. There are many handheld computers with Bluetooth function. It is believed that with the gradual development of handheld computers, Bluetooth function will become a common function. But at present, the price of handheld computers with Bluetooth function is relatively expensive. The handheld computer can also realize wireless connection by using the Bluetooth interface to connect with other devices with the same Bluetooth interface. It has the advantages of no directional restrictions, effective connection distance up to 10 meters, general transmission speed of 1M, fast up to 10M or even faster. However, there are not many electronic devices configured with the Bluetooth interface, and there is a big gap with the popularity of the infrared interface, which is a pity. However, Computers without a Bluetooth interface can achieve Bluetooth interface functionality by installing Bluetooth adapters. These Bluetooth adapters are generally USB interfaces and can be plugged into the computer's USB interface for use. They are only the size of a flash drive and are much more convenient to carry than data cables.
These are some basic configurations. Handheld computer factories also equip handheld computers with other configurations such as LCD display screen, camera processor, etc.
