think that they are differentiated by frequency. In fact, they can all work at 400 MHz, MHz, andMHz. According to Intel official introduction, pxa261 has 16 MB strataflash, while pxa262 and pxa263 both have32 MB. Strataflash is a unique technology of Intel, which can effectively improve the product throughput.PXA27X: Lenovo et960, et980, xiaxin e850, reaching 900, Yutong Mio A700, reaching 818, 828 +, Mingji P50, etc.PXA27XSeries Processors are Intel
arm1136, which can work at up to 330 MHz. The main reason Nokia chose such a high-frequency processor is that their n93 is equipped with a 3.2 million-pixel "Karl Zeiss" autofocus lens and supports 3X optical zoom. At the same time, it can also play full-screen qvga resolution MP4 files, support Wi-Fi wireless Internet access (only for non-Mainland licensed), can record close to the quality of the DVD video, the power is very powerful.

There are two types of 1.JavaScript data: Primitive Type and object type. The original type also includes numbers, strings, and Booleans, as well as null and undefined, which are a collection of properties, and each property has its own name/value pairs, common object types are functions, arrays (array), dates ( Date), Regular (REGEXP), and Errors (error).1.1 Data types can also be divided into mutable types and immutable types. Objects and arrays are mutable types , Numbers, Boolean values, an
Java ScopesMost programming languages provide the concept of a scope. For names defined in the scope, the scope also determinesIts "visibility" and "presence Time". In C,c++ and Java, scopes are determined by the position of curly braces. Refer to the followingExample:As a variable defined in the scope, it can only be used until the end of that scope.In the example above, indented typography makes Java code easier to read. Since Java is a free-form language, extra spaces,Neither the table bit no
