Configuration basic concepts

Configuration is a specification that defines the basic J2ME runtime environment, including a virtual machine and a set of core classes derived from J2SE. Each Configuration corresponds to a group of devices with similar capabilities. For example, a certain configuration may be defined as an embedded device with rich memory and network connection. The virtual machine may be a complete JVM, and the API may be a larger subset of the API in J2SE. Another configuration may be It is defined as a device with less memory and simple network connections. Its virtual machine may be a subset of the JVM, and its API may be a smallest subset of the APIs in J2SE plus a few other specific APIs.

Configure computer configuration

The computer configuration mainly includes CPU, motherboard, memory, hard disk, graphics card, sound card, network card, chassis, power supply, heat sink, display, optical drive, keyboard, mouse, audio and other external devices. The higher the relevant configuration, the more comprehensive this computer is. The more powerful it is, the more expensive it is.

The CPU is the main computing component of a computer, which is equivalent to the human brain. The performance of the CPU directly determines the performance of the computer. The CPU's architecture, clock speed, cache, and number of cores together determine performance. The civilian X86 architecture CPU brand is only two in the world, Intel and AMD. Intel occupies more than 80% of the CPU market. AMD's R & D strength, technology, brand size and annual revenue are all beyond AMD's reach, but AMD is more cost-effective in low-end products. .

The motherboard is an important component of the computer. Most of the hardware needs to be connected to the motherboard. The design, workmanship, materials and quality of the motherboard directly determine the stability and scalability of the computer. The more well-known motherboard brands are Asus (the world's number one motherboard manufacturer), Gigabyte, EVGA (the high-end board brand in the United States), MSI, ASRock (the ASUS sub-brand), Biostar, Elite, Foxconn, Jetway, etc.

Memory is an important temporary storage part of the computer. All the data that needs to be calculated are temporarily stored in the memory. The quality of the memory determines the stability of the computer. Many blue screens and crashes are related to the memory. The more well-known brands include Corsair, Zhiqi, Bodi, Kingston, Jinbang, Micron, ADATA, Apacer, Heijinggang, etc. In addition, Samsung is the largest manufacturer of memory particles.

The hard disk is an important permanent storage component of a computer. All data that needs to be stored permanently is in the hard disk. The architecture, speed, and cache of the hard drive determine its performance. Hard drives are divided into traditional mechanical hard drives and high-performance solid-state drives. The only brands of mechanical hard drives are Seagate (acquired Samsung), Western Digital (acquired Hitachi) and Toshiba (formerly Hitachi). These hard drives have firmware and quality issues, and Seagate's warranty regulations are extremely strict. The solid-state hard disk has a different architecture from the mechanical hard disk. It is more similar to memory and is stored by high-performance flash particles, but the price is higher. The main brands are Samsung, Plextor, Intel, OCZ, Micron, ADATA, GALAXY, Kingston and so on.

The graphics card is an important display computing and output component of the computer, which is equivalent to the human visual nerve and mainly processes image data. The graphics card is divided into an integrated graphics card and an independent graphics card. The integrated graphics card is a display core integrated in the motherboard north bridge or CPU. The independent graphics card has a separate PCB board, memory chips, power supply, cooling and interfaces. The graphics card is mainly used to play games, watch high-definition movies and graphics. The performance of the graphics card directly determines the smoothness of the game and the image quality that can be opened. The core, architecture, frequency and bandwidth of the graphics card determine the performance of the graphics card. The size of the video memory does not determine the performance of the graphics card, let alone the code name of the graphics card. Many manufacturers and gunners use large video memory to mislead consumers. If the core performance of the graphics card is weak, then no matter how large the video memory is, it is useless. Independent graphics cards are divided into desktop home-grade cards and professional cards. The former are mainly used for games and movies, while the latter are mainly used for graphics rendering and are expensive. Graphics chip brands are mainly AMD, Nvidia and Intel. Among them, Nvidia withdrew from the chipset market after 2008 and thus withdrew from the integrated graphics market, while Intel only did integrated graphics. Intel's integrated display can barely reach the performance of entry-level low-end discrete graphics cards, and AMD's new integrated display performance has been greatly improved, reaching the low-end independent display level. Intel's graphics card market share also reached first place due to the high CPU share, while the independent graphics card market AMD and Nvidia are almost equally divided. Nvidia's mid- to low-end alone is a pitman, with high prices and low performance. The new card is weaker than the old card, and suppresses AMD in the high-end market and professional card market. The main brands of independent graphics cards are ASUS, EVGA, Gigabyte, MSI, Zotac, Sapphire, Innolux, Leadtek, Dilan Hengjin, HIS, PNY, etc. The major brands in the mainland are GALAXY, Rainbow, Radium, Yingtong, Mingyu, Onda , Shuangmin (Colorful, Yeston, Mingxuan, Onda, Shuangmin, which are mainly manufactured by Tongde, and are called Tongde Wuhu or Tongde Wugou), Gengsheng (Tongde's own brand), Xiangsheng, etc., In addition, the Shenzhen office card is full of cottage graphics cards.

A sound card is a component that processes sound data and outputs, and is equivalent to the human auditory nerve. All motherboards have integrated sound cards. There is no special need to install an independent sound card. The main brands of integrated sound cards are Realtek. Independent sound cards are divided into built-in and external. The main brands are Innovation, German Tank, Rhythm Tank, Lebon and Asus.

The network card is a component that processes network data and receives and outputs. All motherboards have integrated network cards. There is no special need to install a separate network card. Independent network cards are divided into built-in PCI-E interface, external USB interface, etc. The main brands are TP-LINK, D-LINK, Tenda, Huawei, etc.

The case is an important fixed part of the computer. Although it can be turned on without a case, it is necessary for most people. The chassis directly fixes the motherboard, power supply, hard disk, and optical drive, and also has its own switch and fan wiring connected to the motherboard. The plate, air duct, dust, and radiation protection of the case are very important. The first thing that determines the grade and price of a case is the design of the plate and air duct. The thicker the plate, the lower the probability of resonance of the electronic components (mainly the motherboard and the hard disk), the better the air duct, the better the heat dissipation, and the lower the temperature. Many people don't value the case and think it's just a shell. This is a serious mistake. The low-end iron case easily deforms the motherboard and the heat dissipation is not good. The main brands include Yinxin, Corsair, Lianli, ANTEC, Cooler Supreme, TT, Weixun, Zhenhua, Xingu (Colorful Rainbow), Overclocking Third Class, and colorful, Parkson, Big Buffalo and other low-end brands.

The power supply is the most important part of the computer that provides current output, which is equivalent to the human heart. The power supply converts voltage and current to deliver power to various parts of the computer. The quality of the power supply directly determines the stability of the electrical energy. The workmanship, materials, rated power, output capacity, and conversion efficiency of the power supply directly determine the price and grade of the power supply. Many people do not value the power supply, but this is a very important component. Low-end cottage power supplies can explode and other dangers. They can also burn other hardware due to unstable voltage or insufficient output. Looking at the quality of a power supply is mainly rated power (maximum power has no reference value), output capability (mainly for + 12V output of high-power CPU and graphics card), ripple suppression, voltage deviation, conversion efficiency, etc. The main brands are Haiyun, Corsair, ANTEC, Yinxin, Weixun, Delta, FSP, Bridgeway, Kangshu, TT, Cooler Supreme, etc. The main areas in mainland China are Huntkey, Great Wall, and overclocking. Much. Power supply is currently the most profitable computer hardware, so many brands have broken their scalp to seize the market.

The radiators are mainly CPU radiators, graphics card radiators, chassis fans, memory radiators and motherboard north bridge radiators. CPU and graphics card radiators conduct heat and heat through cooling bases, heat pipes, cooling fins, and fans. The chassis fans run along the air ducts of the chassis. Memory and Northbridge radiators are used less often. The CPU and the graphics card are highly heat-generating components. No heat dissipation or poor heat dissipation will cause the temperature to be too high and restart or even burn directly. The main brands are Owl, Cairong, Limin, Cooler Supreme, TT, Overclocking Three, Kyushu Fengshen and Dongyuan.

The monitor is an important image output display part of the computer. The panel and workmanship of the display directly determine the quality and display effect of the display. The panel is mainly divided into TN and IPS. The quality of the panel determines the display output effect, and the cutting size of the panel determines the size of the display. The mainstream display sizes are mainly 16: 9 and 16:10. 16: 9 is mainly 18.5 inches, 20 inches, 21.5 inches, 23 inches, 23.6 inches, 24 inches, 26 inches, 27 inches, etc., 16:10 is mainly 19, 22, 24, etc. Because 16: 9 can cut more panels and reduce costs, it is called a so-called "golden ratio" by the manufacturer. In fact, the visible area is less than 16:10, but the mainstream large-scale games and high-definition movies are 16: 9 resolution. Rate, can be regarded as "collusion" between manufacturers. (9/16 = 0.5625 10/16 = 0.625, who is closer to 0.618?) The main manufacturers of display panels are EIZO, NEC, Dell, Samsung, TPV, AUO, etc. The backlight of the display mainly includes the traditional CCFL backlight and LED backlight. The latter has been replaced by the manufacturer, and the display is called an "LED display", which is still an LCD. LED backlight is mainstream, because the cost and power consumption are lower, and the resulting display is thinner, but the display effect is still determined by the panel. The main display brands are Samsung, Dell, TPV (8 brands: AOC / Philips / MILO / ELSO / AMARK / Emmison / Maya and Dreamers), Acer, Asus and Great Wall.

The configuration of the notebook is roughly the same as that of the desktop, but there are major differences. The CPU and graphics card are basically soldered to the motherboard. In addition, due to the small space requirements for higher heat dissipation performance, notebooks must not only look at the CPU, memory, hard disk and graphics card. Industrial design, molds and heat dissipation are also very important. For example, the heat dissipation of aluminum alloy mold is definitely better than that of engineering plastic mold. In addition, the CPU and the graphics card are mainly conducted by a heat pipe. Generally speaking, it should be divided into two, but some brands and low-end use only one heat pipe, so the temperature is high.
