With the continuous advancement of technology, smartphones are no longer just a simple tool for making text messages, but they play an unusual role in our lives. Whether they are eating, sleeping, or going to the toilet, they will appear in our In the line of sight, how many people will have the inertia to take out the phone and put it back in the pocket?
Because of this, when we choose a mobile phone, we are just as cautious as choosing a partner. Not only do we require a thin and beautiful appearance, but the hardware is also very important. However, many consumers only know about the hardware in the CPU. In fact, the running memory of the mobile phone (RAM) The impact on mobile phones is equally important. Let's take a look at them below.
The importance of RAM
Just like a computer, all the programs in the mobile phone are also running in RAM, and the RAM read and write speed and capacity directly determine its quality, so the performance of the mobile phone, in addition to the CPU, the phone memory RAM also has a key The role of sex, in general, the larger the capacity of RAM, the better. For a simple example, whoever has more water in the cup and bucket, the answer is definitely the bucket. When the cup is full, the bucket starts. The program running on the phone is like this amount of water. The advantage is obvious, and the processor performance is sufficient. Running a large game, the big RAM phone will definitely be smoother than the small RAM phone.
HTC Dream G1 (192MB)
As the world's first smartphone using Google's Android operating system, HTC Dream is equipped with a Qualcomm MSM7201 528MHz processor, equipped with 192MB RAM and 256MB ROM, although the configuration seems to be somewhat unsightly, but as an Android system The originator is as important as the iPhone. After the mobile phone memory continues to develop, all the way from MB to GB, today's mobile phones are no longer equipped with at least 2GB RAM configuration.
With the increase of mobile phone RAM capacity, a previously ignored parameter has surfaced, that is LPDDR, in fact, before the Samsung Galaxy Note4 mobile phone is generally equipped with LPDDR3 memory, and now more and more manufacturers began to emphasize Your mobile phone RAM uses the LPDDR4 standard.
Magnetoelectric Proximity Switch
The magnetic proximity switch is a kind of proximity switch. The magnetic proximity switch is one of many types in the sensor family. It is made by the use of electromagnetic working principle and advanced technology. It is a position sensor. It can transform the non-electricity or electromagnetic quantity into the desired electric signal through the change of the positional relationship between the sensor and the object, so as to achieve the purpose of control or measurement.
