How to verify RAM in Linux?

You can verify RAM in Linux using several commands. Here are a few common methods:

Using free command:
```
free -h
```
This command displays the total, used, and free memory in a human-readable format.
Using top command:
```
top
```
This command provides a dynamic view of system processes and memory usage. Look for the memory section at the top.
Using vmstat command:
```
vmstat -s
```
This command gives a summary of memory statistics.
Using cat command to read /proc/meminfo:
```
cat /proc/meminfo
```
This file contains detailed information about memory usage.
Using htop command (if installed):
```
htop
```
This is an interactive process viewer that also shows memory usage.

Choose any of these methods to check your RAM status in Linux.
