Computer network professional courses generally include: computer language (programming): such as C language or JAVA language, and other programming tools, such as VB or VC programming; Database technology, computer network technology, network technology and network equipment, web page design and production technology, network security and other courses. Learn some tools and software around these courses, such as web page making tools.
Others may learn some tools and software, such as PHOTOSHOP, video animation processing and editing software, etc.
Since it is a professional study, not a training, I will also study some other public courses, such as English, physical education and politics.
Which school do you want to apply for? You can check the website of this school, or Baidu: the teaching plan of computer network technology specialty. All schools are similar.
It should be noted that different schools may have different professional teaching plans (that is, which courses are different, but the basic professional courses are generally the same). Some schools prefer network application (network technology), while others prefer network development or network security.
