A. VOLATILE MEMORY Volatile memory‚ also known as volatile storage‚ is computer memory that requires power to maintain the stored information‚ unlike non-volatile memory which does not require a maintained power supply. It has been less popularly known as term Dynamic random access memory (DRAM) is a type of random access memory that stores each bit of data in a separate capacitor within an integrated circuit. Since real capacitors leak charge‚ the information eventually fades unless the capacitor

INTRODUCTION Computer is defined as a combination of electro-mechanical devices (Hardware) capable of accepting data or information‚ processing‚ storing‚ and providing output under the control of some instructions and commands called programs (Software). Computers are machines that perform tasks or calculation according to a set of instruction or programs. Introduce in 1940s the first fully electronic computers were huge machines that required teams of people to operate. Compared to those early

bus serves as the communication highway of the motherboard. It links the different parts of the computer to the CPU and the main memory. Its primary task is to send data and instructions to the different parts within the motherboard‚ including the external bus. The external type of motherboard bus‚ which is also known as the expansion bus‚ serves as the interface for peripheral devices like hard disks‚ CD-ROM drives‚ and flash drives to get connected to the CPU. The shape of each interface is unique
