Information technology certification course

IT professional technical certification is a "stepping stone" to enter the IT industry. Professional certificates issued by internationally renowned IT companies prove that you have certain professional IT skills, which are internationally recognized as common skills. These internationally renowned IT companies are: Microsoft, Oracle Bone Inscriptions, Cisco, Sun, Novell, etc. Take Microsoft as an example, its certificates for global promotion mainly include Microsoft Network Engineer (MCSE), Microsoft Development Expert (MCSD) and Microsoft Database Expert (MCDBA). Among them, MCSE is a computer network expert widely valued by the global industry, and the gold content of a MCSE certificate is no less than that of an undergraduate diploma. The "Cisco" certification issued by Cisco, a famous American computer company, has also attracted hundreds of thousands of senior technical talents in the computer industry.

At present, the top certification of 1T industry is often directly linked with leading technology enterprises in the industry, which can be divided into several series, such as network engineering, software research and development, database, application software and multimedia.

MCSD certification

Following MCSE, Microsoft Certified Software Solution Development (MCSD) is also a famous certificate in the field of software research and development. This certificate mainly tests candidates' ability to use Microsoft application services, SQL and other technologies to build network and e-commerce solutions. It is estimated that it will take 4 months, and the cost will be around 30- 1 10,000 USD.

MCSD is one of the best certificates in Microsoft programming environment. One of the biggest benefits of having a MCSD certificate is to go directly to Microsoft. Now few people in the industry have a MCSD certificate. According to the statistics of Microsoft Professional Certification Magazine, at present, there are 654.38+0.5 billion people in the scientific and technological circles in the United States who have this certificate, which is still far in short supply. In addition, it is said that the MCSD certificate and its make-up exam can also make the applicant's resume stand out among many job seekers.

The course of MCSD also teaches enterprise development technology, but the starting point is relatively high. Generally, students who study this course have been using Microsoft products for a long time and have a certain foundation in enterprise-level development technology. Compared with Java programmer certification, MCSD is higher in learning time and learning cost than Java, and it takes more time and energy to obtain this certification than Java certification.

⑥ What do you learn in IT courses?

It should be possible. It is the abbreviation of information technology, which refers to the technology related to information. Different people and books have different explanations for this. But basically everyone agrees that it consists of the following three parts:

-Sensing technology This is the extension and expansion of human sensory organs, and the most obvious example is the bar code reader;

-Communication technology, which is the extension and expansion of human nervous system, undertakes the function of transmitting information;

-Computer technology This is the extension and expansion of the function of the human brain, which undertakes the function of processing information.

The so-called informatization is to transform other industries and industries with information technology, so as to improve the efficiency of enterprises. In this process, information technology plays the role of a powerful tool.

By the way, what is the IT industry? There is a general classification for your reference:

Provide IT basic technology, ic research and development, software writing, such as INTEL, MS, etc.

IT technology productized parts, components, assembly manufacturing such as elite, Volkswagen, etc.

IT products integrate computer and peripheral manufacturers such as Lenovo and IBM.

The third party in IT industry provides various matching services, such as legal consultation and public relations services.

It trains reserve talents in various colleges and universities such as computer specialty.

IT industry cooperates with various associations, * * * *

⑦ What does IT industry mean? Do you need to take any courses?

IT industry is a computer technology industry, including all aspects that can be applied to computers in life, and it needs to learn computer professional knowledge, such as

Understand the composition of computer networks.

Computer network is the combination of computer and communication technology, software and hardware, communication subnet and resource subnet. This understanding can reduce the difficulty of learning online courses. This is also the basic knowledge source of network protocol layering, which is why the network should be divided into communication subnet and resource subnet, because computer network is produced by the combination of communication and computer technology. After being divided into two subnets, the problem is simple. In addition, the communication subnet can be divided into two or three layers, namely, physical layer, link layer and network layer. Then the resource subnet is divided into two layers, namely the transport layer and the application layer.

2. How to learn network protocols?

Hierarchical theory can reduce the difficulty of analysis by layering protocols. Layering and modularization are important analysis methods of computer technology. The computer network is first divided into two layers: communication subnet and resource subnet, and then further divided into communication subnet and resource subnet. In fact, network devices are related to different layers, such as hubs, Ethernet switches and routers. TCP/IP is related to layers, such as IP layer, transport layer and application layer. Network security is related to multiple layers, such as application layer, transport layer, network layer and link layer.

3. Understand the importance of network classification.

It can better help readers to clear their minds and not be like a paste in their minds. For example, by geographical classification, including local area network and wide area network; According to media classification, including copper network, optical fiber network and wireless network; According to the classification of applications, including LAN applications and Internet applications.

4. Be sure to learn the TCP/IP protocol well.

The bottom layer is local area network, wide area network or wireless network, and then the IP layer is used to form a logically complete network to complete the function of communication subnet. TCP completes the communication between application processes, and the application layer completes the application. The essence of learning computer network is to learn TCP/IP protocol, because only a network with complete TCP/IP protocol can be called a real computer network. Therefore, if you learn the TCP/IP protocol well and understand its connotation, you will truly understand the computer network and learn the computer network.

What are the popular training courses in IT industry?

Many popular training courses in the IT industry can be roughly divided into several directions:

Programming and development: java, python and other post-release languages.

Marketing operation rights: Internet marketing, new media operation, global e-commerce, etc.

Design: UI, UE interaction design

Web front end

software test

LINUX cloud computing

The study content and employment direction of training courses in each direction are different. For those who want to enter the IT industry, they should learn from many aspects, make comprehensive comparison and choose the training courses that suit them.
