MEMORY IS THE INTERNAL STORAGE AREA OF THE COMPUTER. MEMORY IDENTIFIES THE DATA STORAGE.THE PHYSICAL MEMORY USUALLY REFERRED TO US MAIN MEMORY OR RAM.
Different types of computer Memory
Hard Disk Drive. The hard disk drives are among the most common types of computer memory. They can store the data and information long term as this is where you store your music, games, documents, and the like. Hard drives work much like records. They are spinning platters that have arms with head to touch the different parts of it. When the head is at a certain location, data and information are either being written or deleted from that area of the hard drive. The largest hard drives available these days are as big as 2 terabytes and can store information up to 70 megabytes every second.
RAM. RAM stand for Random Access Memory. These are electronic types of computer memory that accesses any information any time. These types of memory work reversely like tapes. Since they are electronic, there are no arms, heads and spinning involved. RAM work really fast as they are the ones who bring the information to the brain to be processed. However, all the information and data stored here are short term as after they are processed the RAM frees itself so that more information can be processes by the CPU after.
Flash Memory. Flash memories are types of computer memory that works like RAM but are stable. Even when there is no power, the information and data saved in them are kept safe and secure. They cannot, however, keep as much data and information like the hard disk drive. These are very small and portable devices therefore not much hardware is available, hence the small storage space. At present, the biggest flash memory drives can only hold up to 32 GB of data. Unfortunately, flash memories are slow. The fastest of the flash memories can only read up to 22 megabytes every second.
Tape Drives. Tape drives are types of computer memory that work like tapes or audio
