In 1990, the main frequency of the Intel 486 CPU was 33MHz (at that time, the DRAM memory was operated at 16MHz); In 1993, the first generation of Pentium came out, with a frequency of 75MHz in 2000, Intel's new core could be at 1GHz; In the next few years, the CPU clock speed is mentioned as 6GHz, and in the next 10 years, Intel is developing the next generation of technology, so that the CPU clock speed is expected to reach 100GHz. System performance can only be optimized if the peak bandwidth of the memory data output is the same as the peak input bandwidth of the processor. The peak bandwidth is equal to the product of the bus clock frequency and the number of bytes on the bus.
The program of the computer has the locality of the year, that is, for a period of time, the address used in the sharp sequence in the process is concentrated in a small range, cache - L1 - L2 - internal and external frequency implementation Read-only memory ROM - EPROM - EEPROM - Flash (BIOS) random access memory RAM - dynamic memory DRAM In 1996, EDO increased the working frequency of the memory to 33MHz at that time, and the main frequency of the processor was 66MHz; In 1997, the working frequency of SDRAM memory was raised to 100MHz, and the main frequency of Pentium Pro at this time was 200MHz, after the advent of Pentium in 1998, two years later, the main frequency of the processor reached the PC133 (bus 64-bit, 8Byte) launched by VIA to increase the working frequency of the memory SDRAM.

Today, in infinite silence, I forget the world and myself. I think I'm a tall and luxuriant tree. Although I don't have the fragrance of flowers, the cuteness of small animals, and the wings that fly into the blue sky, I have a great role.
Sister Chun came quietly, I also stretched, my leaf babies also poked their heads out, I smelled the fragrance of flowers, and heard the wonderful ** of the birds. Rustling, the rain came, and the heavy rain gave me a comfortable bath and made my baby leaves look new and more beautiful. The rain, I don't know when it quietly stopped, the sun ran out, let us soak in the sun, we feel refreshed.
The eccentric Grandpa Xia arrived, and the leaf babies were no longer naughty little shoots, but they all grew into big leaves one by one, and put on the most unique coat that belonged to the summer. I don't know which naughty little guy provoked Father-in-law Sun, which made Father-in-law Sun feel very uncomfortable, and sprinkled all his anger on people's heads. "Luckily, there are trees here, so we won't be turned into barbecue.
The two lads walked over as they spoke, and then sat down and leaned against me. At this time, one of them flew over and made a home on me, and from time to time made a cry of 'I know, I know, I know'. In this way, I sang one song after another that belonged to the summer.
Autumn girl followed, and with a flick of her wand, she turned the whole world into a golden yellow, and even my baby leaves changed into a new outfit. At this time, Sister Wind came to me, I knew, I knew, it was time for the Leaves Babies to leave me and live their own lives, and I didn't forget to say goodbye to them when they left, autumn really made me sad.
Brother Winter is ruthless, and like the Autumn Girl, he wields his white wand and turns the world white. I stood there alone, and I couldn't help but look down, and I found that in front of me, a few leaves were almost covered in the dirt, and they moistened me, and I shed tears of emotion. Yes!
The leaves are gone, but they are still with me. They've grown up!
I am a tree, a tree that is not conspicuous.

After the conductor explained the Carmen Overture, the ** meeting began in this music. This is one of my favorite pieces, and it's also called the Matador's Dance, which is the prelude to the opera Carmen. At first it was the sound of a light violin, and I closed my eyes and listened carefully, imagining what the conductor grandfather had just said.
Ah, I can hear the cheerful sound of the violins and pianos playing the cheers of the crowd in the bullring, and the trombone, violin and cello playing a low voice, which shows the majestic and heroic posture of the ancient Roman bullfighters. The whole piece is vibrant, energetic, and uplifting.
I also like Chinese folk music, but what I hear is usually played in folk music. This ** will be unique in the use of Western instruments to play the Cantonese music "backgammon", Jiangsu folk song "Jasmine", although it is different from the folk music played, but the cheerfulness of "backgammon", the lightness of "Jasmine", simple and beautiful are expressed, and the same gives people a wonderful feeling. Reminds me of a sentence:
**Yes. Only ** is borderless.
