In general, large network games in operation, need to occupy a lot of memory, so if you want to upgrade the computer hardware, then the first choice must be memory space, followed by other computer hardware components.
1, upgrade the memory
Before the memory bar is upgraded, Win7 system users should first consider the issue of the
is very good, highly recommended everyone to use! The only downside is that the hardware is changing, and this script is not currently finding the latest updates, and perhaps some of the most recent hardware may not be mentioned in the script. Because it is often at the bottom of the Linux system and sometimes closely related to

There are two times in a Linux system, hardware clock and system time, the hardware clock refers to the clock device on the motherboard, which is usually the clock that can be set on the BIOS screen. The system clock refers to the clock in the kernel. All Linux-related instr

Today's computer is close to full popularity of the degree, it gives people in the work and learning to provide a great convenience, however, the computer's "panic" for ordinary computer users, but become a solution is not open, earn not off the trouble. When the computer is turned on, or when the operating system is started, or when some applications are being used, or when you are about to exit the operating sys
The relationship between Linux device driver and the whole hardware system1, the classification and characteristics of equipmentThe hardware of a computer system is mainly composed of CPU, memory and peripherals.With the development of IC (Integrated circuit) production process, the chip integration is more and more high, often in the CPU internal integrated memo
The Linux clock is divided into the system clock and the hardware clock (Real time clock, referred to as RTC). The system clock is the clock in the current Linux kernel, while the hardware clock is the battery-powered clock on the motherboard and the hardware clock can be se
1. IntroductionThere are two clocks of hardware clock and system clock in Linux. The hardware clock is the clock device on the motherboard, which is usually the clock that can be set on the BIOS screen. This time there is battery-powered maintenance on the motherboard, if the motherboard battery is exhausted, if the power outage, restore to the factory settings.
in the Linux system, the troubleshooting of hardware problems may be the most difficult task in the field of Computer Management, even if the experienced users sometimes encounter their own situation, this article share some practical skills and processing methods, hope to help readers understand, identify and finally solve the hardware problems.

In the beginning to do the real problem, found that the computer system this piece of the problem is always wrong, so will
For the composition of the computer hardware system and the relationship between the parts, we first come to a simple general summary:
The computer hardware
Some Win7 users in the safe removal of the hard drive, found that the hard drive Cdef and CD-ROM also appear in the deleted items, this is how to do? Now let the small series for you to analyze the causes of this problem and its solution.
Reason:
If the computer is using a nforce chipset motherboard and serial hard drive. After all the hardware drivers are installed in the system, it is found that a "Safe
1, especially when the summer comes, hot weather, at this time if the accessories temperature is too high will cause panic, to do a good job of cooling;
2, in the case of small memory (less than 128M), it is best not to run the memory of more software and games or run multiple programs at the same time, this will lead to insufficient physical memory, resulting in panic;
3, today's CPU and display card because of the adoption of a new technology, so have a good overclocking performance, but ove
Preface
All sections earlier in this chapter describe the impact of the software environment in the entire system on the system performance. In this section, we will analyze the impact on the database system from the system hardware environment, we also provide some target
The linux system time is sometimes not synchronized with the hardware Time. Linux clocks are divided into system clock and RealTimeClock (RTC) clock. The system clock is the clock in the current LinuxKernel, while the hardware clock is the clock powered by the battery on the

related to hardware, making it difficult to understand the computer principle or architecture, it is hard to learn the assembly. This also makes many people far away from the assembly, because it is too lazy to learn the assembly to learn computer principles. However, the assembly is such an important language, to learn it, not necessarily to use it, at least you can better understand the computer system a
