How many series are IBM notebooks classified into in totalWhat are the characteristics of each serie

X series: It is a relatively light series, portable, most of them are, and the performance is not bad, and there are also with T7100, but many of them use low-voltage CPUs to save power but the performance is also a little worse; And the tablet is also inside the X series.

T series: The display is really big, the performance is really good, and there is no need for low-voltage CPU, which is pure performance first, which is a bit similar to Dell's XPS series. But it can't be compared.

The stability is also strong, and it is the latest technology used: if you want the best ThinkPad, you can only go to the T series to find.

R series: low-end series: or a bit like Shenzhou, the cheapest thinkpad of the "low-price pioneer" go to R to find it; The configuration of the R series is basically close to that of the T series, and the technology will be a little less, but the quality of the ThinkPad can still be guaranteed!!

It's a screen in general.

Z: It seems to be the most undesirable type, and basically no one buys it.

Leave him alone, I've seen this Z series disappear in a few years.

r is cheaper but of slightly inferior quality.

t The classic of the classics is quite scary.

x Super invincible and high mobility, so light that you don't believe it's a notebook, it feels like you've bought a pound of chicken hair, it's just that there is no built-in optical drive, which is inconvenient.

z Widescreen Entertainment IBM is trying to develop in the direction of entertainment, but I personally feel that widescreen IBM is very nondescript and looks silly.

It's gone, it's all Lenoveo

Now it is divided into the following series.

Entry-level R60i R61i series The entire series of ** is basically below 7000 But it is basically a 15-inch screen The material and workmanship are also the worst in the entire IBM But some basic technologies in IBM are still included in it In fact, it is more suitable for people who do not have too high requirements for machine configuration But have relatively high requirements for the quality of the machine.

The same is the R series, but the R61 machine is obviously much more high-end First of all, the machine is basically based on a 14-inch widescreen It should be the mainstream recommended model of IBM at present The material and workmanship are basically close to the T series The landlord can go to the store to compare the materials of the two That is, the thickness of the machine is relatively thick And it is generally equipped with a 4-cell battery The battery life is not very good But some machines with independent graphics cards in the R61 series are still very cost-effective and definitely worth buying Current** It's basically around 10,000.

Next is the X series in the IBM family This should be known to everyone It is a 12-inch model used by pure business office people It is more suitable for people who often travel or go out to use the fuselage is relatively small and very light and thin The other is equipped with a full-size keyboard Not like a small machine like Sony The keyboard is also shrunk The disadvantage is that it is not equipped with a built-in optical drive, but the material and workmanship are absolutely first-class It can be compared to a reduced T series.

Oh, the king debuts T series can be said to be the king of business notebooks on the market at present, regardless of workmanship and material or heat dissipation Plus the T series exclusive three-year warranty and two-hour quick repair service Plus the latest accidental damage protection of the T61 series It is definitely the first choice for high-end notebooks The disadvantage is that the licensed ** is indeed very high The cheapest price is 10,004 So the T series of parallel goods sells quite well But the quality may shrink a lot in all aspects.

Finally, add a Z series because it has been discontinued, basically not sold because the Z series is IBM's first attempt at a widescreen machine, so it is still commemorative, and the machine is very small, and the materials are also very real, in fact, it was also very popular with everyone at that time, and the disadvantage is that it basically does not have a separate display, so it was directly merged into the T series and R series, so now the T series on the market is divided into standard screen and wide screen.

That's all I hope will help the landlord to buy the machine.

R series - to meet low-end requirements, with engineering plastic housing, reduce costs, for customers who love IBM, but do not have a high budget. There is no shrinkage in functionality and quality, only that the shell is not metal.

X-Series - Super mobile performance. The elite of the IBM family for highly mobile business professionals is housed in an aluminum-magnesium alloy housing with a wide range of IBM patented technologies. Because of the need for mobility, the CPU voltage is lower to reduce power consumption.

The built-in optical drive is abandoned in order to reduce weight.

T series - the highest value in the IBM family, the upper shell is aluminum-magnesium alloy, the base is titanium alloy, the latest product T60 series has added a magnesium roll cage, there is no need to worry about what consequences will happen if the book flies out in a parabolic motion. It adopts a built-in optical drive and a discrete graphics card, a 14-inch standard screen, and an ultra-thin body. Only slightly lower than the X-book in terms of mobility, this is the result of the pursuit of performance-oriented.

Z series - widescreen book, which is equivalent to widening the book of T. Hey, it seems to be a freak born after IBM was acquired by Lenovo.

IBM's host systems are divided into the following four series:

Z (formerly called Z Series).

This series is a mainframe product, independent architecture, IBM has an absolute advantage in the industry.

P (formerly called P-Series).

This series is a UNIX minicomputer product, based on the RISC architecture, the unique AIX operating system, with good openness, the current main competition is only HP and Sun.

i (formerly called i series).

This series is IBM's closed system of AS400 minicomputer system, the processor and P follow IBM's unique POWER series products, which are widely used in the domestic financial industry, but due to the lack of openness, many markets are replaced by the P series.

X (formerly called X Series).

This series of products is used in the most common PC servers, and most of the servers are usually called products of this series, which are based on the open architecture of Intel X86, which is relatively cheap.

The question stem is not clear and cannot be answered.
