These are the static RAM (SRAM) and Dynamic RAM (DRAM).ġ.
There are basically two major types of RAM. You can use RAM in storing data only when the device is on. The name Random Access, as associated with RAM, comes from the fact that memory address termed storage location can easily be accessed. While in smartphones and tablets, you can hardly remove it as it is usually integrated into the device. In personal computers, RAM is installed as a memory module. RAM is a prominent hardware component in most electronic devices like desktop computers, tablets, laptops, and smartphones. Its main function is storing data currently being used by the Central Processing Unit of the computer. It is a kind of computer memory that houses application programs, in-use data, and operating system (OS) so that the processor of the device can easily access them. RAM is an acronym that stands for Random Access Memory. Used in everyday devices such as computers, phones and tablets The major types of ROM memory include PROM, Mask ROM, EPROM, and EEPROM. The major types of RAM include DDR, SRAM, SDRAM, and DRAM.
When the speed of ROM increases, it increases and boosts the overall speed of your personal computer also. The speed of the central processing unit increases when you increase the speed of RAM. Mainly used in firmware such as UEFI, BIOS, Medical devices, RFID tag, microcontrollers, and other devices where permanent memory operation is necessary. It mostly comprises of DIMM modules, SRAM (CPU cache) and DRAM.ĭuring bootstrapping operation, ROM is responsible for storing instructions. The primary memory in most electronic devices is the RAM. Data or contents stored on it save even when the device is off. ROM is a non-volatile type of device memory. Non-volatile memory: Data or contents stored on it save even when the device is off. Volatile memory: All contents stored in RAM are lost when the device is turned off. Most ROM chips come with between 4GB to 8GB storage capacity Most of the chips have storage capacity ranging from 1GB to 1 terabyte The CPU can only access data and information stored on the ROM when the contents are transferred to the RAM Two primary sizes, whether it is used in a laptop or personal desktop computerĭifferent sizes of ROM which depend on its usageĬontents stored in RAM can be accessed directly by the central processing unit of the computer
Permanent: stored data can only be read but never modified or altered Non-permanent: contents, information, and data stored can be modified, rewritten, or deleted as the case may be Mainly an optical drive constructed with magnetic tapes Inserted in a slot on the motherboard, comes in the form of a thin rectangular chip
