I can't deny the advantages and benefits of computer applications, but I can't help but write down the disadvantages of computer operations. 1. Buying computers costs a lot. We welcome and accept the upgrade of the desktop operating system, which constantly brings convenience to our computer operations. However, the premise is that we have to purchase an upgraded computer that is compatible with it. This is a large charge. If the operating system is upgraded and the application software is upgraded, you have to pay for the change of computer. Ii. High system upgrade costs. To install new application software, you must have an operating system that supports it. First, upgrade the operating system. 3. High cost of application software purchase. With a computer and an operating system, I have to pay for the application software. If you want to upgrade the system, you have to spend a lot of money to upgrade the application software. If you buy and install pirated software or download it from the Internet, it is easy to get infected with viruses. 4. File movement is troublesome. Computers are often attacked by computer viruses, and there is a hidden danger in file security. If you want to reinstall the computer, it takes too much time to download the files stored in the computer. 5. Computer cleanup is troublesome. To work in the company, I had to clean up my computer first. I installed some software that didn't actually make sense to myself. what I hate most about durability is that some traces can be completely cleared only by reinstalling the system. Some files that cannot determine the application value occupy a lot of disk space. There is only one way to change your computer into your own computer and reinstall the system. The Troubles are coming again. 6. Poor performance of anti-virus software. The most annoying thing is virus. It's so annoying to kill and kill. The downloaded software is too lethal. Some anti-virus software is completely spam and cannot be identified by viruses. 7. Poor data retention continuity. Every time you change to a computer, you need to download and upload files, and all files cannot be saved in the same place. You can call them whenever you want. It can only be solved by a mobile hard drive. It is boring to upload and download multiple times. 8. Weak file group function. Sending files one by one to a friend or colleague is inefficient. 9. The file sharing function is weak. You cannot set access permissions for different people. Either all or all. The selection of shared target groups is limited. 10. High computer maintenance costs. To maintain normal computer operation, you have to invest a lot of manpower, material resources, and financial resources. Although I have to admit the advantages of computer applications when I look at the problem, I can't help but say more when I think about it.
