The basic hardware system of a computer consists of the host, controller, memory, input, and output components. The middleware and controller are integrated together and collectively referred to as the central processing unit, that is, the CPU we usually call.
Elliptical circles belong to the inner; rectangular ci
sends a parcel. Without an address, he does not know where to deliver it. For example, to read data from a memory unit, the CPU must know the actual physical address of the memory unit to read. Similarly, reading data from memory units on the memory stick also requires the physical address of the memory unit. In other
High CPU usage is a frequent problem for netizens, CPU usage is actually the CPU resources that you run the program, which means that your machine runs a lot of programs at this time. Long-term use will make the CPU for a long time in the hot state will affect the impact of the CPU
the output device.Output device: A device that outputs information from a computer to a user. Commonly used input devices are: monitors, speakers, printers, projectors and so on
We buy computer, if only keyboard mouse, monitor, speaker, we can play computer? Definitely not. So in fact, the computer chassis is th
One processor supportsCommandAndByte encoding of commandsCalled itsInstruction Set architecture ISA.
Although the performance and complexity of the processors manufactured by each vendor are constantly improved, different models are compatible at the ISA level. Therefore, ISA providesConcept Abstraction Layer.
This concept abstraction layer is the ISA model: the instruction set encoding allowed by the CPU, and commands are e
increasing the number of branch prediction units, cache capacity, and elevation frequency seems to be hard to get through. As a result, when a single core processor seems to have come to an end, Intel and AMD have invariably launched their own dual-core processor solution: Pentium D, Athlon x2!
A dual-core processor, simply by integrating the processor core of two (a computer without sound) on a CPU subst

My Computer-Properties to view CPU information
What's the FSB ③cpu mentioned?
FSB is the front-end bus, in simple terms, this thing is the CPU and the external exchange of data, the most important channel. The speed of the FSB processi
Assembled computer friends generally must have a certain understanding of computer hardware, must understand its balance, the balance between components and hardware performance, processor is computer enthusiasts are very concerned about, so what kind of processor is a good processor (CPU)? Generally we look at the mai
structure.Microcode is maintained in micro-storage, each microcode corresponds to one of the most basic micro-operations, also known as micro-instructions, each instruction is a different sequence of microcode composition, this microcode sequence constitutes a micro-program. After decoding the instruction, the central processing unit emits a certain sequence of control signals, and performs a number of mic
core architecture is different, Can not compare the flow processor to see how much performance, under normal circumstances, NV's graphics flow processor number will be significantly less than AMD, to from the flow of the processor to see how much performance, can only own compared with their own, such as 3850 compared with 3450, 8600 compared with 8800.
Of course, just like your CPU frequency is the same as the truth. The general graphics flow
CPU is one of the many parts of the computer, the operation of various processes and the processing of various data needs to be centralized to the CPU to complete. When the computer is turned on, it's time for the CPU to start wor
Central Processor CPU
CPU is the heart of the computer system, computer, especially the rapid development of micro-computer, is essentially the CPU from low-level to advanced, simple one-way complex development process.
1.CPU frequency higher performance? not necessarily. This is in many novice among the misunderstanding. CPU performance depends on a number of comprehensive parameters, not necessarily the root frequency proportional. Of course, in the same series of CPUs, such as Celeron 4, the higher the frequency of high performance. 2. Why Celeron High-frequency Low-energy? And the Fast Dragon series Low-frequency h
feel the bottom of the temperature should be around 55 ℃, then the CPU temperature should be not less than 65 ℃ it. And CPU temperature once more than 75 ℃ and long time work, light is dead, heavy is burnt out. In the process of using a notebook, if it is obvious that the temperature of the keyboard is very high, it is recommended to let your laptop rest.
How to judge
below, the icon jitter and then press the fork, the trouble is dead. In fact, look at the front to know that the iOS software does not need to quit. in fact, the goal of Apple iOS multitasking is to let you forget about multitasking, like iOS3.x of a single task to use multi-tasking, want to run which software run it, do not want to run directly to the home, regardless of how many software in the background, will not slow down the foreground software (this is, the background is suspended state
Classification of ①CPU
CPU brands have two camps, respectively, Intel (Intel) and AMD, the two industry bosses almost monopolize the CPU market, we take apart the computer to see, but also Intel and AMD brand (of course, not excluding the extremely small cottage of the CPU)
High CPU usage is a frequent problem for netizens, CPU usage is actually the CPU resources that you run the program, which means that your machine runs a lot of programs at this time. Long-term use of the CPU for a long time in the hot state will affect the impact of the CPU
