Computer performance can be become slow because

A) running several software applications at the same time
B) printing document at a low resolution
C) using small computer visual display unit
D) increasing the amount of RAM available in the computer

A) running several software applications at the same time

Computer performance can become slow because of the following reasons:

A) Running several software applications at the same time: When multiple software applications are running simultaneously, it can put a heavy load on the computer's processor, memory, and storage. This can lead to slow performance as the computer tries to handle the demands of all the applications.

B) Printing documents at a low resolution: When printing documents at a low resolution, the computer has to process less data, resulting in faster printing. However, if the resolution is set too low, the quality of the printout may be compromised. This can affect computer performance in terms of processing time and memory usage.

C) Using a small computer visual display unit: If the computer has a small visual display unit (such as a small monitor or low-resolution screen), it may limit the amount of information that can be displayed at once. This can cause information to be displayed in a cramped manner, leading to slower performance as the user may need to scroll through or resize windows more frequently.

D) Increasing the amount of RAM available in the computer: Increasing the amount of RAM (Random Access Memory) in a computer can improve performance. RAM is responsible for temporarily storing data that the computer is actively using. With more RAM, the computer can handle larger amounts of data more efficiently, resulting in faster processing and smoother multitasking.
