![]() ![]() ![]() Is it pleasant to use?ĭon Norman, co-founder of the Nielsen Norman Group, coined the term “user experience” in the 1990s. When people use a product, they usually evaluate their experiences according to the following criteria: Similarly, in the digital design world, UX refers to everything that affects a user’s interaction with a digital product. The design of the switch-including the color, material, and physical appearance-may impact how we feel about the interaction. For example, when we want to turn on a light in our room, we interact with a light switch. We’ll start by defining UX, which stands for “user experience.” When we say “user experience,” we’re referring to how people interact with a product. In this article, we will take an in-depth look into UX and answer the following questions: #UNIX PROCESSES STATES HOW TO#Despite this, many are unsure what UX means or how to use the term correctly. ![]() Issuing ‘kill -9’ on a ZOMBIE process ID will not affect it because the ZOMBIE process doesn’t exist.User experience, or UX, is a popular term in the technology and design industries today. The process will be in a ZOMBIE state from the time the child process issues the SIGCHLD signal until the parent process releases the slot in the ‘process’ table. Now, it’s up to the parent process to release the child process slot in the ‘process’ table. ![]() Instead, the process will send a SIGCHLD signal to its parent process. However, it will not release its slot in the ‘process’ table. When a process terminates, it will release all the data structures and the resources it holds. ZOMBIEĪ process will terminate when it calls a ‘system exit’ API or when someone else kills the process. SIGKILL signals will terminate the process, but the SIGCONT signal will put the process back into a RUNNING/RUNNABLE state. When a process is in the STOPPED state, it will only handle SIGKILL and SIGCONT signals. When the process receives this signal it will be suspended/stopped from executing further. In Linux, when you issue the ‘Ctrl + Z’ command it will issue a SIGSTOP signal to the process. The STOPPED state indicates that the process has been suspended from proceeding further. Thus, if you would like to kill a process that is in the UNINTERRUPTABLE_SLEEP state for a prolonged period then you have to reboot the system there is no other way. The process will only terminate after it completes its sleep/waiting operation. On the other hand, if the process is in the UNINTERRUPTABLE_SLEEP state, then the issuing a SIGKILL signal will not terminate it immediately. If the process is in the INTERRUPTABLE_SLEEP state, then issuing a SIGKILL signal (i.e., ‘kill -9’) to the process, will terminate the process immediately.
