DOS Công việc và cuộc thi

DOS stands for Disk Operating System. Most e-commerce stores are running on this computing platform.

All e-commerce stores running on DOS more often face security issues. The operating system may crash, an event that will lead to inconveniences to the customers and the business itself. The more crashes the business faces, the lower its productivity will be. Security issues will have negative impact on your online business. Customer loyalty may fade with time and more often, it leads to loss of business. It is for this reason that business owners are constantly on the search for professionals who will handle and maintain DOS on which their business relies.
