After clicking the mouse a few times, Xing Baohua suddenly had an idea.
Besides antivirus software, another antivirus measure is a system restore card.
This thing is a godsend for public computers; libraries and internet cafes all have it installed. Before restore cards existed, any computer in an internet cafe would have hundreds or even thousands of viruses.
Some companies also use restore cards, but only on public facilities; employee-assigned computers do not have them.
The idea just lingered in Xing Baohua's mind. If the hardware couldn't keep up, it would be a waste of time. This thing looks simple, but it's actually very troublesome to make. There are various protocols to solve, and the drivers also need to be properly configured.
The combination of hardware and software will inevitably result in a high price for the initial product, including R&D costs.
The key is the hardware; a large number of solid-state drives are needed for the ROM.
Otherwise, the program wouldn't be able to accommodate it. These days, only a handful of companies can persist in research and development and production. Samsung is just one of them, and Xing Baohua has filled all the orders, leaving no other production lines to produce anything else.
There is actually another alternative approach, which is also more expensive, but quite feasible: to install the system into the running memory.
As everyone knows, RAM and hard drive are two different concepts. One is used for handling temporary files and caching, while the other stores data files. We can access a file by opening its drive letter.
RAM is generally very small, tens or even hundreds of times smaller than hard drive memory.
Moreover, RAM has a special characteristic: temporary files or caches in RAM disappear and are cleaned up after the computer is shut down.
When your computer lags or you restart it, it will work better because it's essentially clearing the cache.
Similarly, if the system is installed in RAM, all operations will be wiped out as soon as the power is turned off or the computer is shut down. Even the system registry and logs will be thoroughly cleaned, leaving no chance of recovery.
It is based on this principle that the restore card came into being.
This is the most basic principle of a restore card, but it has many drawbacks. The biggest problem is a sudden power outage, and even if you save your files, it's useless; you can only transfer them using third-party tools.
It's very effective against viruses, but it has too many side effects, is cumbersome and troublesome to operate. Not only does it reduce work efficiency, but it also frequently results in the loss of important data and files.
I was so annoyed I wanted to smash it.
When it comes to installing RAM in a system, there's no need to even think about it now. Just imagine how many RAM chips would be needed to handle the size of the system files!
It's bulky, expensive, and not user-friendly. Why would I create something that would just invite criticism?
A short while later, employees from the software park came into Xing Baohua's office to pick up hard drives. Xing Baohua showed them how to use them before letting them leave.
