benefits of encapsulation: the member variables of a class can be read-only or write-only; A class can have a holistic control over what is stored in its member variables; The user of the class does not need to know how the class stores the data and implements the reuse of the code.Static member: Keyword static allows a member variable or method not to be associated with a specific instance of a class. A member variable or method declared through the keyword static can be considered global, and
Tips for beginners for embedded LinuxAt present, Linux as the main force of embedded system, widely used in consumer electronics, industrial control, military electronics, telecommunications/network/communications, aerospace, automotive electronics, medical equipment, instrumentation and other related industries.

Topic content:The NMEA-0183 protocol is designed to establish a unified BTCM (Maritime Radio Technical Committee) standard in different GPS (Global Positioning System) navigation equipment, by the National Oceanic Electronics Association (nmea-the Nation Marine Electronics Associa-tion) set up a communication protocol. GPS receiver According to the standard specification of the NMEA-0183 protocol, the locat
sort stream. Therefore, in parallel computing, some pipelines that contain stateful intermediate operations may require multiple passes of data, or may need to cache important data. Pipelines that contain no-state intermediate operations can be processed at once, with minimal data buffering, whether sequential or parallel. In addition, some operations are considered short-circuit operations. If the intermediate operation is short-circuited when rendering an infinite input, it may produce a limi
provides a similar architecture to the SAN and operates at the file level. Figure 2. Major storage Architectures direct-attached storage Linux supports a large variety of DAS interfaces, including old standards like parallel advanced technology Attachment (at A)-integrated Drive Electronics [Ide]/ata-parallel SCSI, and Fibre Channel as well as new storage interfaces like serial a Ttached SCSI (SAS), serial ATA (SATA), and external SATA (ESATA).

. Third, the length of the MAC address, the method of representation, the method of allocation and its uniqueness the length of the MAC address is 48 bits (6 bytes), usually expressed as 12 16 binary numbers, separated by a colon for every 2 16 digits, such as: ,:xx: -: 0A:8C:6D is a MAC address where the first 6 bits 16 binary number 08:xx: 20 represents the network hardware manufacturer's number, which is assigned by the IEEE (Istitute of Electrical and El
In the Java language, we can use the two basic data types of float and double to represent specific data.These two data types are essentially floating-point numbers (floating-point number), which is a numerical representation of the approximate value of a real number, represented by a valid digit plus a power.Floating-point numbers are used because the computer cannot accurately convert all decimal decimals to binary in the process of using binary operations, and can only be represented by appro
The IDE (integrated-drive-electronics) is now a commonly used external interface, mainly for hard drives and optical drives. Using 16-bit data parallel transmission mode, small size, fast data transmission. An IDE interface can only receive two external devices. The IDE's English is all called "Integrated Drive Electronics", or "Electronic integrated Drive", which is meant to be the hard drive that integra
The IDE is the interface model that connects the hard disk to the DVD and SATA. This is a system file.

Introduction J2ME (Java 2 Micro Edition) is an integral part of Java 2, and it is called J2SE, EE. J2ME is a highly optimized Java operating environment, mainly for consumer electronics, such as cellular telephones, videophone, digital set-top boxes, and car navigation systems. The J2ME is a Java-specific version tailored for consumer electronics and handheld devices. The advent of J2ME has made it possib
1 The status of the J2ME application framework In June 1999, Sun launched the J2ME (Java 2 Microedition,java 2 Pocket edition). J2ME is specially developed for devices that use limited power, limited network connectivity, and limited graphical user interface capabilities to meet the needs of consumer electronics and embedded device development. Today, 7 years later, consumer electronics and embedded devic
