  1. Primary Storage Primary storage is the storage that is directly available to the CPU. It is also known as: • Main Memory • Direct Access Storage • Immediate Access Storage (IAS)

  2. Primary Storage is made up of 2 types of storage RAM and ROM. ROM Primary Storage RAM

  3. What is Random Access Memory This is a collection of memory cells. We can access any cell at any given time, hence the name Random Access Memory (RAM). RAM is considered to be a temporary type of storage as it cannot hold or store data if there is no electric power.

  4. Types of RAM • Static RAM (SRAM) • Dynamic Random Access Memory (DRAM) • Synchronous DRAM (SDRAM)

  5. What is READ ONLY MEMORY(ROM) This is a chip or a group of chips containing instructions for the CPU. Only the CPU has access to this memory type. When we turn on the computer, the CPU gets its first instruction s from the ROM.

  6. Types of ROM • Programmable Read only Memory (PROM) • Erasable Programmable Read Only Memory (EPROM). • Electrically Erasable Programmable Read Only Memory (EEPROM).

  7. Questions • What is the primary Storage? • The acronym ROM stands for? • The part of the computer that reads, interpret and executes program is known as the ? • The electrical path or channel along where bits are transferred is the?
