1 Memory Basics Memory is the workspace for the computers processor. It is a temporary storage area where the programs and data being operated on by the processor must reside. Memory storage is considered temporary because the data and programs will remain there only as long as the computer has electrical power or is not reset. Before being shut down or reset‚ any data that has been changed should be saved to a more permanent storage device of some type (usually a hard disk) so it can

Difference between Static and Dynamic RAM The journey of dynamic and static RAM was initiated in 1960s which was readily developed in 1970s. In recent days‚ the technology is much more user friendly. RAM is classified into two types: Dynamic RAM and Static RAM. Static RAM uses a form of flip-flop to circulate data. It uses almost six transistors for its functioning. On the other hand‚ Dynamic RAM (DRAM) is typically charged on the capacitor in it. Static RAM holds the data in the

It is used in this project to monitor Buck-Boost Converter’s output voltage and the situation when microprocessor hangs. The output Reset pin is connected to the SYS_WARMRST pin of the microprocessor. If the Buck-Boost Converter’s supply voltage goes below the preset value or the microprocessor hangs then the Watchdog Timer resets the microprocessor. Figure A.8 shows the top-view

known as random-access memory (RAM) where data is stored as well as programs that perform calculations. This is a high speed form of storing data that has the capabilities of processing a large number of data characters per second. The more RAM that a computer has‚ the faster the entire system runs. There are various types of RAM that can be found in computers. The random-access memory takes the form of integrated circuits in current times Most types of RAMS are Dynamic Random Access Memory (DRAM);

Grace Loraine M. Borres BSCOE II-3 Assignment No. 1 An internal 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
