1.5 Memory

• Computer Memory: RAM stands for Random Access Memory, which is the main function of allowing the computer to store data for fast access.
• Random Access Memory (RAM): A Volatile Memory, which means it needs to be refreshed with new electricity to hold its data.
• Random Access Memory (RAM): Three main types: SDRAM (Synchronous DRAM), DDR (Double Data Rate SDRAM), and RDRAM (Rambus DRAM).
• Random Access Memory (RAM): Different types of RAM use different voltages and have different maximum speeds.
• Random Access Memory (RAM):Form factors include SIMM (Single Inline Memory Module - 30 pin), SIMM with 72 pin, DIMM (Dual Inline Memory Module), and RIMM (Rambus Inline Memory Module).
• Random Access Memory (RAM):Different motherboards support different forms of RAM.
• Random Access Memory (RAM):The memory’s storage size is measured in bytes, with bytes being the unit of digital information (8 bits).
• Random Access Memory (RAM):Most RAM storage size are measured in GB (gigabyte) or MB (megabyte), with 1 GB = 1 Billion Bytes and 1 MB = 1 Million Bytes.
• Random Access Memory (RAM):Speed determines how fast data can be transferred to the RAM Stick, with Hertz being a measure of frequency and 1 Hz = Single Calculation per Second.
• Random Access Memory (RAM):Memory channels are the way that the motherboard's circuitry helps the data transfer between the DRAM memory and its memory controller.
• Random Access Memory (RAM):Number of RAM Channels can be Single, Dual, Triple, or Quad, with a Dual-channelled Motherboard should use dual channelled RAM sticks for the best performance.
• Memory in computers functions similarly to human memory, allowing the storage and retrieval of information.
• Bits, the basic units of computer memory, are stored in memory cells that can switch between two states, representing 0 and 1, forming the foundation of all information processing in computers.
• Short-term memory in computers, such as RAM and cache, is used for immediate tasks and provides quick access to data for the CPU, but is volatile and cannot retain data when powered off.
• Long-term storage devices, including magnetic, optical, and solid-state drives, store data even when the computer is turned off, but have different characteristics in terms of cost, latency, and capacity.
• Solid-state drives (SSDs) are the latest and fastest type of long-term storage, utilizing floating gate transistors to trap or remove electrical charges, have no moving parts, resulting in faster access times and increased durability compared to traditional hard drives.
• Computer memory degrades over time due to various factors such as heat, charge leakage, and physical deterioration, researchers are exploring new materials and technologies to enhance memory devices' speed, size, and durability.
