CHF 2 (MOD 5)

• RAM


  Primary storage, where information is processed
• Primary memory


  Volatile, data is lost when computer is shut off
• Memory


  • Stores electrical instructions and data that the computer needs to access quickly
  • Data is stored there for easy access
  • One of a computer's essential parts, without it the machine could not function as intended
  • Needed for hardware, software, and operating system
• RAM


  Temporary storage that provides short-term data access and storage for applications
• More RAM


  • Allows for faster access to and reading of data that would otherwise need to be written to hard drive or SSD
• SRAM


  Static RAM, stored data using flip-flops made of transistors, faster access times, doesn't require periodic refreshing
• DRAM


  Dynamic RAM, less expensive to store data, but data integrity had to be periodically refreshed
• SDRAM


  Synchronous Dynamic RAM, synced data transfers with CPU clock, enabling more rapid and effective memory access
• DDR SDRAM


  Double Data Rate SDRAM, moves twice the data transfer rate of SDRAM by enabling data transfer on both rising and falling edges of clock signal
• DDR Versions


  • DDR1
  • DDR2
  • DDR3
  • DDR4
  • DDR5
• DIMM


  Dual In-Line Memory Module, RAM module that adds several RAM chips to a computer system using a particular pin connector, enhancing CPU, data transfer, and throughput speeds without using more power
• Single Channel Memory
