RAM (Random Access Memory) is a type of temporary memory that allows a computer to store data that is actively being used by the operating system and applications. It enables fast access to running programs and system processes, helping the computer perform tasks smoothly and efficiently. RAM is significantly faster than a hard drive or SSD, but it does not retain data when the computer is powered off. Adequate RAM improves system speed, responsiveness, and multitasking performance. What...

In laptops and personal computers, temperature refers to the level of heat produced by internal hardware components as they perform various tasks. This heat is primarily generated by the central processing unit (CPU), graphics processing unit (GPU), voltage regulators, and other electronic circuits, which naturally warm up when electrical energy is converted into computational work. The temperature increases further during resource-intensive activities—such as gaming, video rendering, or...
