MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -RAM speed is measured in Megahertz (MHz), millions of cycles per second so that it can be compared to your processor’s clock speed.

Detailed explanation-2: -Computer memory (RAM) is typically installed in megabytes (MB) or gigabytes (GB), typically in some combination of 256 MB, 512 MB, 1 GB or 4 GB. For Windows 10: Right-click on the Start button, click System. Installed memory (RAM) is listed.

Detailed explanation-3: -Each stick of RAM has a set amount it can store, as indicated by 1GB, 2GB, and so on. What does the GB stand for? This is short-hand for a “gigabyte, ” a measurement of data that equals roughly 1 billion bytes.

Detailed explanation-4: -Both RAM and hard disk capacities are measured in bytes, as are file sizes when you examine them in a file viewer.

Detailed explanation-5: -Your CPU processes many instructions from different programs every second. Some of these instructions involve simple arithmetic, while others are more complicated. The clock speed measures the number of cycles your CPU executes per second, measured in GHz (gigahertz).
