How do I check my memory information?
You can also quickly find out the total amount of memory installed on the device using these steps: Open Start. Type Command Prompt, right-click the top result and select the Run as administrator option. Confirm the total amount of physical memory (in megabytes) installed on your computer.
What is process ID in Linux?
In Linux and Unix-like systems, each process is assigned a process ID, or PID. This is how the operating system identifies and keeps track of processes. … The first process spawned at boot, called init, is given the PID of “1”. pgrep init 1. This process is then responsible for spawning every other process on the system.
What is Linux zombie process?
A zombie process is a process whose execution is completed but it still has an entry in the process table. Zombie processes usually occur for child processes, as the parent process still needs to read its child’s exit status. … This is known as reaping the zombie process.
What is Pstree in Linux?
pstree is a Linux command that shows the running processes as a tree. It is used as a more visual alternative to the ps command. The root of the tree is either init or the process with the given pid. It can also be installed in other Unix systems.
How do I list all processes in Linux?
Check running process in LinuxOpen the terminal window on Linux.For remote Linux server use the ssh command for log in purpose.Type the ps aux command to see all running process in Linux.Alternatively, you can issue the top command or htop command to view running process in Linux.Feb 24, 2021
How load is calculated in Linux?
The value can be roughly defined as the number of processes over the past minute that had to wait their turn for execution. Unlike Windows, Linux load average is not an instant measurement. Load is given in three values – the one minute average, the five minute average, and the fifteen minute average.
How do I overclock my RAM?
There are three main ways to begin overclocking memory: increasing the platform’s BCLK, directly commanding an increase in the memory’s clock rate (multiplier), and changing the timing/latency parameters.
How do I find the top process in Linux?
top. The top command is the traditional way to view your system’s resource usage and see the processes that are taking up the most system resources. Top displays a list of processes, with the ones using the most CPU at the top. To exit top or htop, use the Ctrl-C keyboard shortcut.
How do I find the process ID in Linux?

How do I check my RAM specs?
The number after DDR/PC and before the hyphen refers to the generation: DDR2 is PC2, DDR3 is PC3, DDR4 is PC4. The number paired after DDR refers to the number of megatransfers per second (MT/s). For example, DDR3-1600 RAM operates at 1,600MT/s. The DDR5-6400 RAM mentioned above will operate at 6,400MT/s—much faster!
How do I check my RAM frequency physically?
If you’re using a windows PC with windows 8 or above, then go to task manager> performance, then select RAM/Memory and this will show up the information about form factor, frequency, how many slots are available and occupied etc.
How do I find the process ID in Unix?

What is process ID in Unix?
In computing, the process identifier (a.k.a. process ID or PID) is a number used by most operating system kernels—such as those of Unix, macOS and Windows—to uniquely identify an active process.
Where is orphan process in Linux?
An orphan process is a user process, which is having init (process id – 1) as parent. You can use this command in linux to find orphan processes. You can put the last command line in a root cron job (without sudo before xargs kill -9) and let it run for instance once per hour.
