Top 10 IT hot technologies in 2007

The second Annual Meeting of China Electronic Information Innovation Technology in 2007 sorted out the hot technologies that may appear in 2007, and selected the top ten IT hot technologies such as multi-core technology, virtualization technology, service-oriented architecture, etc. These hot technologies cover various fields such as computer, network communication and microelectronics.

I remember that at the first Annual Meeting of China's Electronic Information Innovation Technology in 2006, we had predicted the twelve hot technologies in 2006. These include digital TV standards, RFID, open source software and open source models, SATA/SAS, SoC, 3G/WiMAX, SOA, vertical magnetic recording, CMP, virtualization technologies, VoIP, grid applications, and more. After a year of development, we are pleased to find that many of the hot technologies are being accepted by users around the world and in China, and have been turned into products and started to apply! Let's hope the same is true of our top 10 IT hot technologies for 2007.

1. Multi-core technology

In recent years, the most significant shift in CPU technology has been to abandon the performance improvement approach based on increasing the CPU frequency, and to integrate multiple processor cores (CMP) in a single chip to improve the performance of the processor.

There is no denying that multi-core processors are on the rise, becoming an important factor to promote the development of microprocessors in the future. At the same time, the application of multi-core processing is entering various fields, and the development of applicable multi-threaded software is the key to whether users can truly accept multi-core products in the future.

In 2007, the impact of multi-core on the IT industry at both the technical and application levels will be profound and significant.

2. Virtualization technology

Virtualization technology can hide some of the complexity of the infrastructure, users do not need to know where the server, storage device, network or application is, as long as in a simple way to get it, the complexity behind the user can not see. At the same time, IT has the function of automatic recovery, when the system fails, it can automatically diagnose and automatically recover by changing the IT configuration.

IT can be said that the adoption of virtualization technology in enterprise IT systems has been the trend of The Times. In 2007, the use of virtualization technology will continue to expand, and users will benefit from it.

3. SOA

Service-oriented architecture (SOA) allows users to reuse software and connect resources without restrictions, so long as IT is willing to use standard interfaces, it can quickly build different services from existing software components like building blocks.

It can be said that the emergence of SOA has changed the whole thinking of enterprise software architecture design. In 2007, the adoption of enterprise SOA will gradually deepen.

4. WiMAX

As a supplement to 3G technology, WiMAX technology has been attracting much attention. The reason why WiMAX can set off strong winds and waves is related to many of its own advantages, such as longer transmission distance, can provide more high-speed broadband access, excellent last-mile network access services and multimedia communication services. Driven by Intel, MOTOROLA and other companies, WiMAX is bound to become the mainstream direction of the communications industry in the next few years.

In 2007, the effect of major manufacturers' investment in WiMAX may be concentrated, and the application of WiMAX will be strongly promoted.

5. HSPA

HSPA has been successfully commercialized, and the benefits are emerging. It consists of two core technologies: one is HSDPA(High Speed Downlink Packet Access), which can achieve a rate of 14.4Mb/s on the downlink; The other is HSUPA(High Speed Uplink Packet Access), which can achieve rates of up to 5.76Mb/s on the uplink. HSPA is capable of providing much higher data rates than existing 3GPP R99 and WCDMA can support.

With HSPA, operators are able to offer more advanced services to the mass market at a lower cost.

6. Identity management technology

Security risks from within the enterprise and external regulatory requirements have led more and more enterprises to take the journey of identity and Access Management (IAM) applications. What IAM brings to the enterprise is

The positive impact in terms of competitiveness, productivity, integrity and credibility has become one of the key technologies in enterprise applications. By automatically managing visitors, logs, and reports for resources and services, and enforcing business, confidentiality, and security policies, identity and access management improves password management and all aspects of an organization's operations.

In the future, identity management technology will be favored by more and more enterprises.

7. TD-SCDMA

In the competition with the 3G standards proposed by Europe and the United States, China's TD-SCDMA has officially become one of the global 3G standards, which indicates that China has occupied a relatively favorable position in the competition of the mobile communication industry.

In 2007, TD-SCDMA plays a very important role in the 3G mobile communication technology to be adopted in China, and its commercialization level directly affects the development of 3G application and technology in China.

8, 45 nm process

The advancement of semiconductor manufacturing process technology is like the wheels of a train, getting faster and faster. The 90 nm production process technology only entered the mass production stage in 2004; By 2007, the market will usher in 65 nm technology, so 2007 is called the key year for 65 nm process to enter the market; At the same time, Intel has successfully developed the first 45nm processor in early 2007, and plans to officially market in the second half of this year.

The advent of 45nm technology chips means that the world semiconductor industry will enter a new era, which will directly affect the development of many industries.

9. Ruby

Ruby is an interpreted, convenient, object-oriented scripting language that was released by Yukihiro Matsumoto(known as Matz) in Japan in 1993. It is very suitable for text file processing and system management tasks, and is completely object-oriented; Its syntax is simple, extensible, and cross-platform. Ruby is completely free and open, and we can not only get it for free, but also use, copy, modify, and distribute it freely.

In 2007, Ruby's impact on the development environment will begin to be felt.

10, mobile wireless digital broadcasting (mobile TV)

In the future, the mobile phone will no longer be a phone, but a multimedia terminal that can obtain all kinds of information. In the future, the number of mobile TV subscribers around the world will increase rapidly, creating an astronomical business opportunity.

Mobile TV is already available in different parts of the world. From the current technological development, the information transmission mode of mobile TV can be divided into the following: First, the way based on terrestrial broadcasting, the main standards include DVB-H technology in Europe, T-DMB technology in South Korea, etc.; The second is based on satellite transmission, the main standards include South Korea's S-DMB and Europe's DVB-S technology; The third is 3GPP MBMS technology and streaming media technology based on mobile network.

In 2007, mobile TV, which uses mobile communication technology for uplink and terrestrial broadcasting for downlink, will become popular. (in no particular order)

About the selection

In the development of the IT industry, technology and application are two major driving forces that can not be ignored. Through the outlook of hot technologies and applications, we can grasp the future development trend of the IT industry. As the No. 1 IT media in China, ComputerWorld has long focused on technology and application, relying on a large number of expert resources to introduce the development trend of technology to readers, and regard this as an important mission. At the end of each year, we rely on the wisdom of experts to review the technological development of the past year and look forward to the hot technologies in the coming year. Our editors have come up with nearly 100 candidate technologies based on extensive expert consultation; On this basis, each technology is scored according to four criteria.

The outlook is scored according to the impact, innovation, potential and popularity of the selected technologies in 2007, namely: Impact index: the overall scope and intensity of the impact of the technology; Innovation index: the performance of technology in terms of innovation; Potential index: the potential for development over a period of time; Adoption Index: Prospects for adoption in 2007.
