Learning GoalsThe second chapter is to learn character and string processing, in order to better understand the content of this chapter, I added additional auxiliary content: storage mode (big-endian storage and small-end storage), character encoding scheme (see it). The following are the learning objectives of this chapter:1. Big-endian storage and small-end storage2. Character encoding scheme3.ANSI and Unicode characters, strings, Windows Custom data types (for ANSI and Unicode compatibility)A
To buy a dual-core computer, you must first understand the dual core.
Look at Intel and AMD's respective dual-core, we focus on learning their differences, only after understanding to know, choose which is better, or more cost-effective.
To be correct, the use of Intel and
Recently, the hype over dual-core processors has been so widespread that the understanding of the technology seems to be out of the truth. Both AMD and Intel are praising the merits of their dual-core processors through their websites. Such campaigns are timely, as most industry watchers believe the dual-core processor
Today, the hype about dual-core processors is so widespread that the understanding of the technology seems to be out of the truth. Both AMD and Intel compliment the merits of their dual-core processors on their web pages. Their campaigns are timely, as most industry watchers believe the dual-core processors will be in
Linux module is such a code block that can dynamically connect to the core at any time after the system is started. When we no longer need it, we can detach it from the core and delete it. A Linux module is a device driver or pseudo-device driver, such as a network device or a file system.
Linux provides two commands for us: using insmod to explicitly load the core
Now when it comes to processors, the word "double core" should inevitably be talked about. Looking at the full street dual-core processor ad from Intel Corporation, no one would suspect that 2006 would be a dual-kernel processor. But from the various reports of the relevant dual-core processor, I find that many of the

, which is much worse than native, in addition, the latter has a relatively high cost, and the advantage is that the development of multiple cores is much faster than that of native.
Hyper-threading
With hyper-Threading Technology, one core has two threads, so two cores have four threads. Generally, two cores have only two threads.

At present, the two largest manufacturers of CPU processors for civilian use are

Computer Hardware Reviews:
On the processor side, Intel Pentium G630 is an upgraded version of the popular G620 mainstream starter processor, the latest performance better entry-level desktop level processor, which, although positioned to get started, is close to the AMD four core 63
Intel officially confirmed that the next generation of desktop processors based on the new Nehalem architecture will follow the "core" (core) name, the "Intel Core i7" series, the name of the extreme edition is the "Intel

The NetBurst architecture has been in its 7th year since its release in 2000. Over the years, the processor in this architecture has been changing, with the core experiencing Willamette, Northwood, Prescott, Cedar Mill, Processor process from the first 0.18 micron to 65 nm, the main frequency from the initial 1.3GHz to the current 3.8GHz, processor cache, front-end bus and such as HT technology, EM64T, eist technology, etc. are added to the Ne

graphics switch requires the system kernel to support it. If you want to perfect the system kernel support, it is best to use more than 3.0 of the kernel, coupled with the perfect configuration of the line, Linux under the dual graphics card configuration is not very convenient, can only use the command to configure.

Recently, many projects have been paying more and more attention to the dual-core technology. although the early dual-core technology was proposed by some server manufacturers, such as IBM and HP, with the universality of technology, dual-core technology is no longer available for high-end devices, for example, dual-core
Dual core vs. Dual CPU: AMD and Intel's dual-core technologies also have a very different physical structure. AMD has two cores on a die (crystal), connected through a direct-attached structure, higher integration. Intel would encapsulate the two cores placed on different die (crystal), so someone called Intel's solution "dual
