What does TM on the computer model mean?
"TM" is commonly seen in foreign trademarks. It is the abbreviation of "trade mark" in English. "Trade mark" in Chinese means "commercial mark", so "TM" means "trademark". The function is to tell people that the graphic or text marked on it is the trademark of this product or service, not a name or an advertisement.
When the trademark has not become a registered trademark, the "TM" mark is marked. This is to tell the public that this graphic or text is used as a "trademark" for goods or services, not a name or an advertisement. Publicity, so as to prevent the graphics or words marked on it from flowing into the public domain and not being able to apply for registration as a registered trademark and enjoying exclusive rights; at the same time, the "TM" mark can also be used as proof of using the graphics or words as a trademark and apply for registration When using a trademark, you have the prior right to use it.
The commercial equivalent of "TM" is the "R" mark.
"R" is the abbreviation of "register" in English. "register" in Chinese means "register". Marking goods or services with this mark tells people that the graphics or words marked on it are not only trademarks. , and it is also a registered trademark and is protected by national laws. No other individual or organization can use it without authorization.
When a trademark becomes a registered trademark, the upper right or lower right corner will be marked with an "R" or "note" registration mark, or it will be directly marked as a "registered trademark". Remember that the registration mark must be placed in the upper right corner or lower right corner of the trademark, which is stipulated in the "Regulations on the Implementation of the Trademark Law of the People's Republic of China".
Another point to note is that after applying for trademark registration and obtaining the "Notice of Acceptance" issued by the National Trademark Office, but before the "Trademark Registration Certificate", you still cannot mark the trademark as registered. mark, because the issuance of the "Notice of Acceptance" by the National Trademark Office is only the beginning of the trademark registration process. This "Notice of Acceptance" only indicates that the Trademark Office has accepted the trademark registration application, but does not indicate whether the application has been approved. In fact, a considerable number of trademark registration applications have been accepted by the Trademark Office, but were rejected after review, and ultimately failed to be registered. Therefore, during this period, only "TM" should be marked, not "R". Otherwise, it will constitute an illegal act of counterfeiting a registered trademark and will be fined accordingly.

3. Display card naming rules
There are two types of display cards, one is N card and the other is A card.
Nvidia (nvidia) naming rules:
The general versions are GTX, GTS, GT, and GS. The order is GTX ＞GTS ＞GT ＞GS
GS ( Entry level) regular version or simplified version of GT.
GT (mainstream level) common gaming chip. One level higher than GS because GT does not reduce pipelines and vertex units.
GTS (performance level) is a version between GT and GTX, an enhanced version of GT
GTX (GT eXtreme flagship level) represents the most powerful version and is simplified to become GT
Version level:
In addition to the above-mentioned standard versions, there are also some special editions. The special editions usually add a suffix after the model number of the standard version. Common ones are:
GE is also a simplified version but slightly stronger than GS. The GALAX graphics card is used to represent the "hardcore gamer version" of stuff
ZT is down-clocked again on the basis of XT to lower the price.
XT is the downclocked version, and in ATi it means the highest level.
LE (Lower Edition) is basically the same as XT, and has also been used by ATi.
SE is similar to LE and is basically a simplified version of GS, the lowest-end models
MX is an affordable version, popular type, such as the famous MX440
Ultra in GF8 The series used to represent the highest level, but the name of the highest level of the 9 series was changed to GTX.
GT2 eXtreme dual GPU graphics card.
The previous usage of TI (Titanium) generally represented the high-end version of nVidia.
Go is for mobile platforms.
TC (Turbo Cache) is a graphics card that can occupy memory
GX2 (GT eXtreme2) refers to two graphics cards integrated into one graphics card through SLI parallelization. It is different from SLI has only one interface. Such as 9800GX2 7950GX2
Since the G100 series, NVIDIA has renamed the suffix version of the graphics card to make the product line more tidy

p>GT represents the mainstream product line GT120GT130 GT140 GTS250 (9500GT 9600GT 9800GT 9800GTX+)
G low-end entry-level product G100G110 (9300GS 9400GT)
AMD (ATI) naming rules :
ATI graphics cards are named according to certain rules. Graphics cards with the same core and different models are named according to different naming rules to facilitate consumers to distinguish between levels.
The first digit indicates the product generation number, such as 6870 and 6970, which represent the 6th generation chip. The second digit represents the level (series) division, the bigger the better, for example, 6970 is better than 6870. The two are different chips, 9 is the highest level and 8 is the next highest level. The third digit represents the performance gap (model within the series) of the same chip. The bigger, the better. The 6970 is better than the 6950. They are the same chip. The latter has a bit of a flaw, such as a stream processor, and its frequency is also lower now. Mainstream: 6 series: HD6990 (single card dual core, flagship!), 6970, 6950, 6870, 6850, 6790 5 series: HD5770, 5750, 5670
There are also some special editions, special editions are usually Add a suffix after the model number of the standard version. Common ones are:
SE (Simplify Edition) usually only has a 64-bit memory interface, or the number of pixel pipelines is reduced.
Pro (Professional Edition) high-frequency version is generally slightly higher than the standard version in terms of the number of pipelines/number of vertices and frequency.
XT (eXTreme high-end version) is the high-end version of the ATi series, while nVIDIA is used as the low-end model.
XT PE (eXTreme Premium Edition XT Platinum Edition) is a high-end model.

What do the a, b, and c on the CPU model mean?
The following is excerpted from "Computer News"
Pentium 4(P4)
The first P4 processor was the P4 1.5GHz processor released by Intel on November 21, 2000. In the past four years since then, the P4 processor has evolved with the specifications. Continuous changes have resulted in processor families with nearly 10 different specifications. Among them, "P4 XXGHz" is the simplest P4 processor model.
Among them, the early P4 processor used the Willamette core and Socket 423 package, with a 256KB secondary cache and a 400MHz front-end bus. Later, due to changes in interface types, P4 products using Willamette core and Socket 478 packaging appeared. At present, what we call "P4" generally refers to the P4 processor that uses the Northwood core, has a 400MHz front-end bus and a 512KB secondary cache, and is based on the Socket 478 package. Although the specifications are different, the names of these processors all use the "P4 XXGHz" naming method, such as P4 1.5GHz, P4 1.8GHz, and P4 2.4GHz.
Pentium 4 A (P4 A)
With P4 as the model benchmark, it is not difficult to understand P4 A.
Shortly after the launch of the P4 processor based on the Willamette core, Intel released a new generation of P4 using the Northwood core, a 400MHz front-end bus and a 512KB secondary cache in order to improve processor performance. Since the two processors overlapped in some frequencies, in order to make it easier for consumers to identify, Intel added a capital letter "A" after the overlapping P4 processor based on the Northwood core to indicate the difference, and thus the product was born. Processor products such as P4 1.8A GHz and P4 2.0A GHz. We need to remind everyone that among these new P4 products that do not overlap in frequency with the early P4, they still use the name "P4", such as P4 2.4GHz.
Pentium 4 B (P4 B)
After the Northwood core was fully promoted, Intel decided to improve the P4 processor again and launched a 533MHz front-end bus based on the Northwood core. P4 processor with 512KB L2 cache. Although these processors have the same core architecture and L2 cache capacity as the P4 A, performance has also been improved due to the front-end bus being increased to 533MHz. In order to distinguish it from the P4 A processor with the same main frequency, Intel added the letter "B" after the processor name. P4 without frequency overlap does not need to add a letter suffix. Representative products of this type of processor include P4 2.4B GHz and so on.
Pentium 4 C (P4 C)
In the second quarter of 2003, Intel carried out a large-scale upgrade to the Northwood core P4 processor. Not only did the front-end bus of the processor change from The original 533MHz was increased to 800MHz in one fell swoop, and the improved P4 processor can also support hyper-threading technology (because the processor still uses the Northwood core, the processor's secondary cache capacity is still 512KB). This upgrade completely established the P4 processor's leading edge in the market, and the product model was accordingly changed to P4 C. Among them, P4 2.4C GHz and P4 2.8C GHz are the two most representative processors of this series. They were also Intel's flagship products in the mid-to-high-end market from May 2003 to the first half of 2004.
Pentium 4 E (P4 E)
Entering 2004, Intel released the new Prescott core and used it to promote the next generation P4 processor based on the LGA 775 package. However, considering the compatibility with existing platforms, Intel launched the P4 processor based on the Prescott core using the Socket 478 interface. These processors have 16KB of primary data cache and up to 1MB of secondary cache, supporting enhanced hyperthreading technology. Since Prescott P4 also overlaps with the original P4 B and P4 C in frequency, Intel named Prescott P4 P4 E to show the difference. Currently, the price-effectiveness ratio of P4 3.0E and P4 2.8E on the market is very good, and they are very popular among mid-to-high-end consumers.
It should be noted that there are some special products in the P4 using the Prescott core. Their front-end bus is only 533MHz and does not support hyper-threading technology. The main purpose is to replace the original P4 A, The market share held by the P4 B series. Perhaps due to market division considerations, Intel has classified such "shrunken" Prescott P4 processors into the P4 A series, such as P4 2.4A GHz and P42.8A GHz. I hope everyone will pay attention to the difference when purchasing.
Pentium 4 5XX (P4 5 series)
In response to several newly released processors, Intel formulated a new processor naming specification in April this year, introducing the "processor "No." concept. The specification stipulates that the processor number corresponding to the P4 processor based on the Prescott core, with an 800MHz front-end bus, 1MB secondary cache, supporting hyper-threading technology and using an LGA 775 package is the 5 series (i.e. P4 5XX).
Take the P4 520 as an example. It has a main frequency of 2.8GHz, which is basically the same specifications as the P4 2.8E. The only difference is that the P4 520 uses an LGA 775 package, while the P4 2.8E uses a Socket 478 package.
Pentium 4 Extreme Edition (P4 Desktop processor products. The early P4 XE used the Northwood core, with an 800MHz front-end bus and a 512KB secondary cache to support Korean technology. In order to improve the performance of the processor, Intel spared no expense to add a level 3 cache with a capacity of up to 2MB for the P4 XE, which is unprecedented among Intel's desktop processors. From the above specifications, it is not difficult to find that the early P4 XE was actually a P4 C processor with an additional level 3 cache.
With the upgrade of the P4 core and packaging form, Intel released the P4 3.4XE GHz processor in the LGA 775 package in April this year. The processor is based on the new Prescott core and is also equipped with 2MB Level 3 cache can be regarded as an enhanced version of the P4 5XX series. Since the manufacturing cost of previous generations of P4 XE processors is extremely high, and the price is also quite expensive, the performance improvement is not proportional to the price. It seems that only extremely enthusiastic players can experience the fun of "value for money".
Pentium 4 F (P4 F)
P4 F is Intel's first 64-bit processor product released for the desktop market. It is based on the Prescott core, uses a 0.09 micron process, has an 800MHz front-end bus and a secondary cache with a capacity of up to 1MB. Unlike the P4 5XX series, the P4 F processor has built-in Intel EMT64 computing technology and is compatible with both 64-bit and 32-bit computing. Several P4 F processors currently launched on the market all use LGA775 packaging. It is still unknown whether products in Socket 478 packaging will be launched in the future. In terms of performance and price, the P4 F is also a high-end product for hardware enthusiasts.
Celeron (Celeron)
Since the advent of the Celeron processor, although the core, packaging form and specifications of the processor have changed many times, Intel has always maintained the "Celeron" Yang" a model. As for the "Celeron III" and "Celeron IV" that everyone usually hears, they are all created by users or dealers and do not comply with official specifications. At present, the common Celeron processors in the low-end market mainly include "Celeron IV". This series of processors uses the Northwood core, has a 128KB secondary cache and a 400MHz front-end bus, and does not support hyperthreading technology. The Celeron 1.8GHz and Celeron 2.4GHz products that everyone is very familiar with belong to this series of products and are Intel's main force in the low-end market.
Celeron D 3XX (Celeron D 3 series)
Celeron D 3XX is a new generation of Celeron processor derived from P4 E. It uses the Prescott core, but cancels In order to support hyper-threading technology, the front-end bus frequency and secondary cache capacity have also been reduced to 533MHz and 256KB respectively. Since Intel had already started to implement new processor naming rules when this series of processors was launched, the letter "D" was added after the original name "Celeron" to show the difference, and it was classified into the "3XX" series (such as Celeron D 325). The emergence of Celeron D 3XX better bridges the market gap between low-end P4 and traditional "Celeron 4", and its excellent performance has also been recognized by the market.
What does HD on the headphone model mean?
In audio, HD means High Audio, which means high-fidelity audio;
In video, HD means high-definition format or High compression format refers to High Definition. What does the series on the water pump model mean?
The number of stages on the water pump model refers to the number of water pump impellers.
There is only one impeller, which is called a single-stage pump, and the number of stages is 1 (generally not marked). The number of stages above 2 is called a multi-stage pump. The number of stages of the water pump must be marked. For example, level 3 means there are three impellers. Generally, the larger the series, the higher the lift.
Multi-stage pump: It is a water pump in which the inlet and outlet sections and the middle section are combined together through tie rods. Its outlet pressure can be very high, and it is also a type of centrifugal pump. The impeller is the core part of a multi-stage pump. It generally has a higher speed and a higher water pressure. The impeller must pass a static balance test before assembly. What does EI on the switch model mean?
It’s not interesting, it’s just a number, just like the various model numbers of Nokia. . . What do the letters on the lathe model mean?
