As we all know, using a camera to take pictures requires sensitive materials to record images. The sensitive material of traditional cameras is film, while the sensitive material of digital cameras is light sensitive elements (CCD or COMS). Compared with the area of 35mm film, if the size of the sensor area is close to or equal to that of 35mm film, it is a full frame size. The SLR camera with this size is a full frame SLR camera.
The mobile network has become a part of our daily life. Mobile phones can't leave the mobile network without sending WeChat messages to watch live games. However, many users will find that some mobile phones need to cache and play games when watching live broadcasts, but some mobile phones do not. Even if you use the same operator's network, the transmission speed of the mobile phone network will vary greatly at the same time and place. What? This may be because your phone does not support carrier aggregation. What is carrier aggregation? Next, we will introduce the carrier aggregation technology and the application of high pass carrier aggregation technology in detail.

Cell phone NFC and Bluetooth has now been very widely used, the principle is the radio transmission technology, but they have a fundamental difference.
After paying attention to the Wi-Fi signal strength you also need to pay attention to the Wi-Fi security level, which can help prevent information loss and even prevent scraping behavior.
This word is believed that as long as you are familiar with the digital field, you will not be unfamiliar with it. Resolution is the precision of screen image, which refers to the number of pixels displayed by the display. Since the dots, lines and surfaces on the screen are all composed of pixels, the more pixels the display can display, the finer the picture will be, and the more information can be displayed in the same screen area, so the resolution is one of the very important performance indicators. The whole image can be thought of as a large chessboard, and the resolution is expressed by the number of intersection points of all longitude and latitude lines.
SSDs have been sold for a long time. However, at present, mainstream installations are still purchasing traditional mechanical hard disks, while most SSDs are installed in high-end configurations. Due to the small capacity and high price of SSDs at present, few mainstream users choose SSDs. However, with the development of technology, it is also a trend that SSDs gradually become mainstream. Next, we will introduce the advantages of SSDs and the differences between SSDs and ordinary HDDs.
