With the popularity of the Internet, the amount of data in computer records has increased greatly, and the difficulty of calculation has also increased. It is difficult to meet the growing demand for data resource processing using traditional approaches to information processing. Based on Big data and cloud computing technology, this paper briefly analyzed the computer information handling technology under the Big data network environment, and summarized hthe computer collection methods, processing means and management modes for network data information. The experimental results show that computer information processing based on big data and cloud computing technology has significant advantages in the big data network environment. Through the use of big data and cloud computing technology, a large amount of network data and information can be processed and managed more effectively.
