A type of OS that enables more than one applications to run at the same time is called __ a. Multijobing b . Multitasking C.Multiprocessing d Multieventing

## Step 1<br />The problem is asking for the type of operating system (OS) that allows more than one application to run at the same time. The options provided are: a. Multijobing, b. Multitasking, c. Multiprocessing, and d. Multieventing.<br /><br />## Step 2<br />Let's analyze each option:<br />- Multijobing: This term is not commonly used in the context of operating systems.<br />- Multitasking: This is the correct term. Multitasking refers to the ability of an OS to execute multiple tasks or processes simultaneously.<br />- Multiprocessing: This term refers to the use of two or more central processing units (CPUs) within a single computer system. While it can enhance multitasking capabilities, it is not the term that specifically describes the ability to run multiple applications at the same time.<br />- Multieventing: This term is not commonly used in the context of operating systems.<br /><br />## Step 3<br />Based on the above analysis, the correct answer is b. Multitasking.
