Introduction Today, computers are becoming more and more powerful, and the need for a larger amount of memory is needed for these juggernauts of the digital age. Secondary storage is used also, yet the focus is still on the primary units of storing this treasury of information used to run the modern beasts. Hoseya and I shall show you the types of memory that are used in todays computing giants, and other variants that are used to support them.

ROM-Random Access Memory Random Access Memory, or ROM, is a more reliable storage. Data stored in the ROM will remain even if the power is turned off. ROM is usually used for firmware and other software that is used for important processes. Data stored in this chip is rather difficult to edit and to access, and some older models cannot be edit even if you did access it. Models that this applies to are older mask-ROM chips, which are no longer in use.

Read Only Memory-PROM One variation of ROM, is Programmable Read Only Memory. The primary difference between ordinary ROM and PROM, is that PROM is programmed after the chip is manufactured. They tend to be used with video game consoles, cell phones, and other less substantial electronic devices, and shares the same purpose as ROM chips..

Read Only Memory-EPROM EPROM, or Erasable/Programmable Read Only Memory, is the newest type of ROM that, unlike its predecessor, can be modified after its conception. Though a drawback to it is the hard process required to erase the memory, which involves UV light. It is similar in use to both of the former ROM chips mentioned.

RAM-Random Access Memory RAM, or Random Access Memory, tends to be used for temporary files stored upon your computer. These files include precautionary copies of word files and other documents. It also helps the speed the processing power of your computer. Unlike ROM, however, RAM does not permanently saves its memory and is lost upon shutting down the computer.

Random Access Memory-DRAM DRAM, or Dynamic Access Memory, stores it's temporary memory in a separate capacitor per bit. Since capacitors leak charge, the memory fades without periodic refreshing. DRAM is used mostly for its structural simplicity, and high density.

Random Access Memory-SDRAM SDRAM, or Synchronous Dynamic Random Access Memory, is a faster, more powerful RAM drive. Yet it is not efficient on its own. It tends to be used as a compliment to other RAM drives and their functions. The SDRAM is one of the most widely used pieces of hardware in a computer.

Caches A cache is used for the duplication and storage of frequently used programs. These programs will be easier, and faster, to access once the cache stores them.

Registers The Register is a small amount of storage inside the CPU, on the contrary to external storage devices. Its use in modern computers, however, is crunching memory and transferring it elsewhere

Prologue and thanks. Thank you, class, for listening to our presentation about the servitors of processing. We appreciate you bearing with us, and hope you had some insight into what you may use to further increase your storage. For whatever reason ;)
