TOP linux - how to understand?

Question

linux

TOP is open in front of me and nothing is clear to me.
Can anyone humanly decipher the data it outputs?

1. What is "US"? Contradictory, it says CPU % and some US. What it is?
2. How to simply see the overall CPU load as in Windows?
3. What is there to replace this stray, so that it is understandable for people?

Answer 2

1. What is "US"? Contradictory, it says CPU % and some US. What it is?
You need to read a little about the operation of the OS.
US - USR - USER is the CPU usage by user processes. That is, all programs.
SY - SYS - SYSTEM - by the kernel (including its modules and drivers, which is why SYS can include the load not only directly from the CPU, but also waiting for a response from devices)
2. How to simply see the overall CPU load as in Windows?
So in the line %Cpu(s): this is visible.
3. What is there to replace this stray, so that it is understandable for people?
Windows and Linux are different operating systems. Kernels work differently. The amount of information collected about each process is different. On the one hand, Windows collects more information and can display it more conveniently. On the other hand, Linux does not waste time on this and many processes run faster on it at the same time.
Therefore, in this chic utility, everything is clear for system administrators and experienced users.
If you are not one of them, do not use Linux.
