Memory Types and Characteristics
Flash memory is a type of non-volatile memory that can retain data even without power. While it offers the advantage of permanent data storage, it is slower in speed. On the other hand, DRAM is a type of volatile memory that requires power to maintain data. In other words, if the power is turned off, the data is lost. With a larger capacity, DRAM helps in faster processing of tasks, making the computer faster. Therefore, when running multiple programs simultaneously, a computer with a higher DRAM capacity is preferred.

CMOS Image Sensor Operation and Advantages
Charged Coupled Device (CCD) technology is a type of image sensor that differs from CMOS in how it operates. While CMOS image sensors utilize a low-power approach with the sensor converting light into voltage at each pixel to amplify the signal and produce the image, CCD works differently in handling image data.
One of the key differences between CCD and CMOS is in their pixel structure. CCD has a more complex structure involving a series of capacitors at each pixel that sequentially transfer charge across the array before the signal is read out. This results in a slower readout process compared to CMOS.
Another important distinction is in power consumption. CCD sensors tend to consume more power compared to CMOS sensors due to the continuous transfer of charge during the readout process. This can impact battery life in devices using CCD sensors.
Despite these differences, CCD sensors have historically been preferred for applications requiring high-quality image capture, such as professional photography and scientific imaging, due to their superior image quality and sensitivity in low-light conditions. However, advances in CMOS technology have narrowed the gap in performance between the two sensor types, making CMOS sensors a popular choice for many consumer electronic devices like smartphones and digital cameras.
In conclusion, while CCD and CMOS sensors have their unique characteristics and advantages, the growing popularity of CMOS sensors in various applications showcases the evolving landscape of image sensor technology.CMOS Image Sensor, CIS works on the principle of converting light into electrical signals. One of the main advantages of this technology is its low power consumption, making it ideal for smart devices where battery life is crucial.
