Smart TV cold knowledge: Do not tell the difference between RAM and ROM

Some time ago, Xiao Bian chatted with a friend. The friend said that he bought a new mobile phone. I asked how much memory it was. He casually replied "64G, and now the mainstream is 64G." Under the sigh of admiration, I feel that it is still necessary to give a description of RAM and ROM; after all, whether it is a smart TV, a TV box, or a mobile phone or a computer, memory is the key parameter that determines its performance, and between RAM and ROM. The difference between the words is very confusing.


RAM:

Random memory, an internal memory that exchanges data directly with the CPU. Ready to read and write at any time, read and write quickly and so on, is the operating system of the intelligent terminal or the temporary storage medium of the running software. This kind of memory will lose its memory content when power is cut off, so it is mainly used for short storage. Time usage program.


RAM is also called main memory, running memory, and memory. It is actually a "memory stick" in a computer. As the direct data reading unit of the CPU, it directly affects the operating speed of the smart terminal and the upper limit of multi-task operation.


ROM:

Read-only memory is a solid-state semiconductor memory that can only read out previously stored data. Its characteristic is that once the data is stored, it cannot be changed or deleted. It is usually used in electronic or computer systems that do not require constant data changes, and the data does not disappear because the power is turned off.

Although the ROM is also an important component of the smart terminal, it has meaning and price is much lower than RAM. In the computer industry, ROM is called "hard disk" and it determines the upper limit of the storage capacity of smart terminals (programs, pictures, music, video, etc.).

Written at the end:

Many people believe that the bigger the RAM or ROM, the better. This is actually a very one-sided view. For RAM, which is more important to the system, even with the consideration of price, larger memory has higher requirements for operating systems and device motherboards. Take the 32-bit Windows 7 system as an example, the maximum memory address of the system. For 4GB, it can be seen that the memory is actually the same as the selection criteria for smart TVs and TV boxes. Only the most suitable one is not the best (currently 2GB for the mainstream memory of the box and 3GB for the smart TV).

Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, etc. on TV boxes, smart TVs, smart TV software, etc. Answering questions.

Impulse Turbine

An impulse turbine is a turbine that is driven by high velocity jets of water or steam from a nozzle directed on to vanes or buckets attached to a wheel. The resulting impulse (as described by Newton's second law of motion) spins the turbine and removes kinetic energy from the fluid flow.
The impulse turbine is the simplest type of turbine. It consists of a row of nozzles followed by a row of blades. The gas is expanded in the nozzle, converting the high thermal energy into kinetic energy.
