Memory is an important concept in both computers and mobile phones. Some netizens asked what is the difference between the memory in computers and the memory in mobile phones? How to understand the two? If you don’t understand, friends together Take a look!

How to understand the difference between the memory in computers and mobile phones

Many friends always say I need memory when installing computers 500G, there is no difference between memory and hard drive. In mobile phones, both are called memory, but the computer's memory is relative to the running memory in the phone, and the hard drive is relative to the storage memory in the phone.

Computer memory is a card-like part, a rectangular strip, plugged into the motherboard. Information cannot be stored permanently in the memory strip. Once the computer is powered off or shut down, the information will be gone. At present, The capacity of the computer's memory is generally between 2GB and 4GB.

The computer's hard drive is directly plugged into the motherboard. The capacity and volume are larger than the memory stick, and the weight is much heavier. The connection to the motherboard is through A data cable, the hard disk also needs the power supply in the host box to power it, so there is also a power cable. The capacity of the hard disk is currently more than 500GB in the mainstream configuration of computers.

Supplement: Common memory maintenance tips

1. For memory golden fingers and graphics card oxide layer failures caused by dust, we should use rubber or cotton dipped in alcohol to clean them, so that they will not The screen will be black.

2. Regarding the problem of mixed memory insertion, when upgrading memory, try to choose the same memory as your existing one. Don’t think that buying new mainstream memory will make your computer perform better. On the contrary, it may cause Lots of questions. Principle of mixed memory insertion: Insert low-standard, low-standard memory into the first memory slot (that is, DIMM1).

3. When only one memory needs to be installed, the memory socket close to the CPU socket should be preferred. The advantage of this is that it can be cleaned when the memory is contaminated by dust brought out by the CPU fan, and the socket It is extremely difficult to clean after being contaminated.

4. Install the memory module. There is a latch on both sides of the DIMM slot. When the memory gap is correctly aligned and plugged in, the two teeth should automatically lock the memory. . There is only one notch on the gold finger of DDR memory. The two sides of the notch are asymmetrical and correspond to a ridge on the DIMM memory slot, so the direction is easy to determine. For the previous SDR, there were two gaps, and it was easy to determine the direction. However, SDR has gradually faded out of the market, so it doesn’t hurt to learn about it. When pulling out the memory, you only need to move the two latches outward. , the memory will automatically come out of the DIMM (or RIMM) slot.

Check the memory labels: The genuine Kingston memory labels are printed clearly and regularly, while the fake ones are obviously rough and light, and the fonts appear relatively thin. In addition, the formatting rules of real and fake Kingston memory labels are also very different, so please observe carefully.

Check the memory particles: It can be clearly seen from the Kingston memory particles in the picture that the genuine Kingston memory particles are clearly printed, while the fake memory particles are very dim, in sharp contrast to the genuine ones. For a memory, the PCB circuit board only accounts for about 10% of the cost of the memory, while the memory particles are the focus of determining the price of the memory. Therefore, usually the PCBs of fake products are basically manufactured by regular OEMs, while the particles are made of "white flakes" in the jargon, which is what we call defective products. They are cheap but have poor stability and compatibility.

Check the registered trademark logo: the genuine Kingston’s registered trademark? R Another point, carefully observe the watermark inside the label. There are obvious traces at the connection between the fake memory watermark and the KINGSTON font, proving that it was post-printed, which will not appear in genuine Kingston memory.

Gold finger identification: The following is the gold finger of a genuine Kingston memory. The gold fingers of genuine Kingston memory are pure in color, and the gold finger connection parts in the purple square are gold-plated; the gold fingers of counterfeit Kingston memory are slightly dull, and the gold finger connections in the red square are copper sheets of the PCB board and are not Gold plated.

Identification of fonts on the PCB: The left is genuine Kingston memory. Genuine Kingston memory has uniform fonts with no obvious size difference, and has relevant certification symbols. The counterfeit Kingston memory has different fonts and no relevant certification symbols.

K-label: This is a macro shot using a SLR camera, and the flash is turned on to capture the authentic and fake labels. The laser pattern of the authentic label can see dense silver powder particles. The K-character is not obvious, and the background appears. blue. The letter "K" on the counterfeit label is very obvious, and the density of the silver powder particles is low.

Flip the angle to view anti-counterfeiting: The laser anti-counterfeiting label of genuine Kingston memory can show two patterns by changing the angle. The first pattern has a silver powder effect on the upper half and a half K stain on the lower half. ; The second pattern has a silver powder effect on the lower edge and a half-K shape on the upper edge. The counterfeit label has only one pattern, which is a very obvious K word.
