Data converters are used to convert and condition signals from analog to digital and vice versa. They are integrated into the device to convert digital signals to analog signals and vice versa. The use of data converters in the devices enhances the processing, data transmission, and process control capabilities. These data converters are based on the architectures that are proprietary architectures of companies such as Analog Devices and Texas Instruments or are patented. The core of these data converters is either based on complementary metal-oxide semiconductor (CMOS) or silicon or silicon on germanium materials forming the essential gateways for signal conversion and conditioning. There are two types of data conversions:

Cloud computing is the use of computing resources where systems are connected by public or private networks to offer scalable infrastructure for applications and file storage. It offers a pool of resources that includes data storage, specified applications, and networks and computer processing power. Across regions, governments and private organizations are accelerating education digitization through various monetary and non-monetary initiatives. In an attempt to ensure equality in education and improve the quality of learning content, educational institutions have begun to implement services such as cloud computing and LMS. Within the education ecosystem, cloud computing helps students, faculty, and education organizations to use software and hardware managed by third-party service providers. Cloud computing can play a significant role in improving the quality of delivering higher education without compromising on the regulated and restricted learning environment.
