Video card (graphics card) full name display interface card, also known as display adapter, is the most basic configuration of computer, one of the most important accessories. As an important part of the computer host, the graphics card is the equipment of digital to analog signal conversion, and it undertakes the task of output display graphics
the graphics card is connected to the main board of the computer, which converts the digital signal of the computer into an analog signal for the display. At the same time, the graphics card still has the ability of image processing, which can help the CPU work and improve the overall running speed. For those engaged in professional graphic design, graphics card is very important. Civil and military graphics chip suppliers mainly include amd (ultra micro semiconctor) and NVIDIA (NVIDIA). Today's TOP500 computer, including graphics card computing core. In scientific computing, graphics card is called display accelerator
Disk capacity unit: because the computer is binary, K is used to be called a thousand. The storage capacity of computer hard disk usually uses byte (B, byte), kilobyte (KB, kilobyte), megabyte (MB, megabyte), Gigabyte (GB, Gigabyte) and terabyte (TB, terabyte)
petabyte (PB), Exabyte (EB), zettabyte (ZB), yottabyte (Yb), brontobyte (BB), nonabyte (NB), doggabyte (DB), etc
calculation method:
1, 1dB = 1024nb
2、1NB=1024BB，
3、1BB=1024YB
4、1YB=1024ZB
5、1ZB=1024EB
6、1EB=1024PB
7、1PB=1024TB
8、1TB=1024GB
9、1GB=1024MB
10、1MB=1024KB
11、1KB=1024B
extended data
calculation method:
in the computer, binary is used. In the computer world, it will be more convenient and neat to process byte in batches with the power of 2. 1KB per 1024byte, 1MB per 1024KB, 1GB per 1024MB, 1TB per 1024gb
In the international system of units, TB, GB, MB and KB are the counting units of "1000 base system", so the International Electrotechnical Association (IEC) has drawn up & quot; KiB"、“ MiB”、“GiB" The binary unit of 1024 carry is used to mark the data size of 1024 carryand hard disk manufacturers take every 1000 as a base, 1KB for every 1000 bytes, 1MB for every 1000KB, 1GB for every 1000mb, 1TB for every 1000gb
in the operating system, the carry of capacity calculation is 1024, and it is not changed to & quot; KiB"、“ MiB”、“GiB" This difference causes the hard disk capacity to "shrink"
take 120GB hard disk as an example:
calculation method of manufacturer's capacity: 120GB = 120000mb = 120000000kb = 120000000000 bytes; Conversion to operating system calculation method: 1200000000 bytes / 1024 = 117187500kb / 1024 = 114440.9mb / 1024 = 111.8gb
Simple algorithm: hard disk capacity / (1024 * 1024 * 1024)8000000000 / (1024 * 1024 * 1024) = 74.5gb
400000000 / (1024 * 1024 * 1024) = 37.25gb
hard disks need to be partitioned and formatted, there are differences between operating systems, and the behavior of ing files when installing the operating system, the hard disk will take up more space, So in the operating system, there will be a difference between the capacity of the hard disk and the nominal capacity, and the difference between the two types of hard disk capacity in 5% - 10% should be normal
T: Express train number. The number of express trains is now headed by the letter T. the speed of express trains is faster, the stops are less, and the car body is more advanced. Generally, it only stops at the stations of provincial capital cities, sub provincial cities and a few major prefecture level cities
k: fast passenger train. The number of express passenger trains starts with the capital letter "K", which appeared after China's first large-scale railway speed increase. Most of the passenger cars are red 25g cars, also known as "red leather cars". There are also a small number of direct stops at medium and large stations of prefecture level cities
extended information
other trains:
1, Z: direct express train. This kind of train does not stop at one station ring the journey or has to stop but does not handle passenger service. The bottom of this kind of train is 25t, and all of them are air-conditioned trains
2. N: fast passenger train in management. Such trains generally stop at some prefecture level administrative centers or important county-level administrative centers and other important stations. This kind of train appeared after the fifth railway speed increase and only operated inside the Railway Bureau
L: temporary passenger train. At the peak of passenger flow, the temporary passenger express stops at the county-level cities and most of the county-level medium and large stations. This kind of train generally runs in spring, summer and National Day holidaysreference materials

int * t = & K
here is to apply for a t pointer and assign it to the address of K
int * t< br />t=&k;
the meaning is the same as above, just write separately
separate t = & K; This can be understood as assigning the address of K to the T variable (whether it is a pointer or not)
t: aspirated plosives in the tip of the tongue. When pronouncing, the tongue is stretched forward and the tip of the tongue is against the upper gingiva to form an obstruction point; Then exhale a breath from the lungs, stop behind the obstruction point, and make a momentum to the outside; Finally, the tip of the tongue suddenly opens up, allowing a strong air flow to break through the obstruction point and burst into sound.
If it is Chinese, the pronunciation of the two initials is as follows
t: when pronouncing, the tip of the tongue is against the upper gums. After holding the breath, it suddenly leaves and the air bursts out of the mouth
k: when pronouncing, the front part of the base of the tongue, against the upper soft palate, obstructs the air flow, so that the air flow breaks through the obstruction of the base of the tongue and bursts into a sound
< / blockquote >if you know the correct pronunciation action, or you are not accurate, it may be that the coordination of the pronunciation organs and muscles is insufficient. If you are a child and younger, you can guide more and let the child practice. If you are over five years old, or the guidance has no effect, you can ask us for help< br />
in the initial consonants of Chinese Pinyin, K is a lingual hind sound, aspirated sound, unvoiced sound and stop sound. When pronouncing, the back of the tongue is against the soft palate, the back of the soft palate rises, blocking the nasal passage, the vocal cords do not vibrate, and the strong airflow breaks through the obstruction and bursts into sound.
Intel Core's CPU model with t stands for low power consumption, and its performance is also lower. With K stands for overclocking. After overclocking, its performance will be greatly improved, and its heating and power consumption will also be improved
extended data:
"CPU overclocking" is to force the CPU to work at a frequency higher than the nominal frequency, so as to improve the performance of the computer through overclocking. There are two ways to overclocking: increasing the frequency multiplication coefficient and increasing the external bus frequency. External bus frequency is what we often call 66MHz, 83MHz, 100MHz, 133MHz, etc. Frequency multiplication coefficient is the ratio of CPU working frequency and CPU internal frequency, such as 3 times, 5 times, etc
at present, the word "KT board" is also called China, which is one of the few countries in the United States. Other countries are basically called foam board
so it's just convenient to call, just know
have a good time!
