It fetches instructions from memory, interprets them, and then issues commands to the other parts of the computer to carry out the instructions.<\/p>\n<p>The logical unit is responsible for performing logical operations, such as AND, OR, and NOT. The memory unit is responsible for storing data and instructions. The output unit is responsible for displaying the results of computations.<\/p>\n<p>Here is a more detailed explanation of each option:<\/p>\n<ul>\n<li><strong>A. Logical unit<\/strong>. The logical unit is responsible for performing logical operations, such as AND, OR, and NOT. These operations are used to manipulate data and to make decisions. For example, the logical unit might be used to compare two numbers and to determine which one is greater.<\/li>\n<li><strong>B. Memory unit<\/strong>. The memory unit is responsible for storing data and instructions. Data can be stored in memory for a short period of time, such as while a program is running, or for a long period of time, such as when a file is saved. Instructions are stored in memory so that the control unit can access them when needed.<\/li>\n<li><strong>C. Output unit<\/strong>.
