According to Parsons and Oja (2014), they state that a "microprocessor is an integrated circuit designed to process instructions" (p 67). Its main role is to process data quickly once instructions have been received. A microprocessor is usually advertised by the speed of the microprocessor in gigahertz. Some of the most popular chips are known as Pentium or Intel-Core. When purchasing a computer, the microprocessor is one of the essential elements to look at before selecting the computer. The faster the microprocessor, the faster your data will be processed while navigating the software. Memory There are four types of memory. These are RAM, ROM, EEPROM, and the Bootstrap loader. RAM, also known as Random Access Memory, is the temporary space where the processor places data as it is used. This allows the computer to quickly find the required information without having to search through hard drive space. Once information has been processed and stored on a permanent storage device, it is erased from RAM. RAM also houses the operating system
