Nowadays, with the rapid development of science and technology, computer technology has been integrated into people's lives. Think about the computer technology 10 years ago and today's computer technology, which is really a world of difference and has undergone earth-shaking changes. At the same time, the application of big data is more and more extensive, which brings huge profits, and various "clouds" emerge one after another, which puts forward higher competition and requirements for computer information processing technology under the background of big data. This paper first introduces the concept of big data, expounds various computer information processing technologies based on the background of big data, and analyzes these technologies, and finally analyzes the future development opportunities of big data.

Keywords: big data; Computer information; technical study

With the rapid development of science and technology, the application of big data is more and more extensive, and the resulting data system is huge and huge, which puts forward higher requirements for computer information processing technology in the era of big data. How to deal with big data in an orderly way is worth discussing by every postgraduate.

I. The concept of big data

What is big data? Big data, another way of saying it is huge data, is a very complex and dense data set. In a certain period of time, such data sets can't be managed, captured and processed by traditional common data processing software, which needs innovation and new processing mode. Big data has the characteristics of virtualization, on-demand service and low cost. From every consumer's point of view, the computing technology resource service in big data can help every big data user complete the desired resource information. Users can use it directly by paying, without searching for information and asking around. This fundamentally changes the way people demand information resources and provides users with a super-large-scale network resource. At the same time, in the face of massive large database resources, how to deal with big data resources and obtain the information resources that users want requires continuous excavation of computer information technology.

Second, computer information processing technology under big data

Generally speaking, computer information processing technology based on big data can be divided into the following three aspects: information acquisition and processing technology, information storage technology and information security technology. The following three technologies are studied and analyzed. 1) information acquisition and processing technology. Information collection and processing technology is the first step to realize informatization and the most basic work content. Only after the information data collection is completed can the following computer information technology processing be carried out. Therefore, if you want to collect information, you must first make clear the target source of the information, monitor the information data, keep abreast of the information flow and trends, and then input the collected information data into the computer database to realize information collection and collection. Next is the second step, information processing. The core of all processing technologies lies in guiding users, which is completely user-oriented, setting the screening range of information, determining the richness of information and so on. Finally, according to the requirements of users, the information resources are transmitted to users. In this way, the whole process of information from collection to processing and then from processing to transmission is realized. 2) Information storage technology. Under the background of big data, the storage of information technology is the key link of the whole computer information processing, which can save the processed data and make it more convenient for users to retrieve and apply the data. And now the total amount of information data is large and the update speed is fast. Reasonable use of storage technology can quickly realize information storage, improve work efficiency and simplify complexity. Nowadays, the most widely used technology is distributed data storage, which is very convenient and can realize fast and massive data storage. 3) Information security technology. While big data is convenient for users to use and enjoy, the security of information data resources can not be ignored. Moreover, with the development of society, the security and privacy of data resources have gradually attracted attention. How to realize the security of database is a very worthy research topic. The first and most important thing is to establish a computer security system and fully introduce more talents. Secondly, we should speed up the research and development of safety technology. Due to the rapid development and update of big data, it is necessary to update the original security system quickly to adapt to the update speed in the era of big data as soon as possible. In addition, it is necessary to strengthen the monitoring of information to prevent illegal people from stealing data, and to provide a stable and effective security system under the huge amount of information and data.

Third, the development prospect of computer information technology under big data

1) The development of cloud technology is an inevitable trend. Cloud computing network technology has been developed more and more. On the one hand, due to the limited data processing technology of computer hardware system, cloud technology can completely get rid of its disadvantages. At the same time, it can make use of the latest data resources and processing technology, and does not depend on the computer hardware system. Therefore, with the huge data becoming more and more complex, traditional data processing methods can no longer adapt, and computer information processing will definitely develop to cloud computing in the future. 2) Computer network is no longer limited by computer hardware. In the future, computer network technology will no longer be limited by computer hardware, network transmission technology will be more open, computer network and computer hardware will be separated, and a new network architecture will be redefined. 3) Computer technology and network are integrated with each other. Traditional computer technology needs to use computer hardware system to realize information processing, processing and storage. In the future, new computing technology will be separated from computer hardware equipment, and data processing and processing can only be realized through computer networks. At the same time, the two will integrate with each other and truly meet the troubles brought by the update in the era of big data, which is another direction of computer technology development under the background of big data in the future.

Fourth, the opportunities and challenges faced by computer information technology under big data.

Under the background of big data, opportunities and challenges of computer information technology coexist. First of all, viruses and malicious attacks on websites are indispensable, which is a huge challenge in front of computer information technology. At the same time, in recent years, online fraud has been increasing, social attention has gradually increased, and network security issues have been ignored. Moreover, the transmission speed between information is limited, and innovative transmission technology is needed to meet higher user needs. Finally, with the continuous enrichment of large-scale databases, the data resources for processing and processing are more and more huge, and there are new requirements for data storage. How to adapt to the increasing amount of data information, realize more convenient retrieval and meet the needs of users is also a huge challenge. There are also many opportunities. First of all, big data requires higher and higher information security, which promotes the development of information security to a certain extent. Secondly, in terms of application, big data has brought great convenience to enterprises and users, and also enriched industrial resources. In the future, the competition between users and enterprises may turn into the competition of big data information resources. Finally, with the advent of the era of big data, a new situation with information security, cloud computing and Internet of Things as the main core has been built.

Verb (abbreviation of verb) conclusion

Through some research, at present, in the era of big data, computer information technology does have some drawbacks and needs continuous innovation and development. I believe that cloud computing will become more and more advanced in the future and will be more and more integrated into people's lives and work. Computer information technology is facing great challenges and opportunities. Facing the challenge and seizing the opportunity, I believe that China's computer technology will get better and better in the future, and it will definitely surpass the world's leading level!
