CPU Benchmarks: Measurements used to compare performance between processors. Memory: Random Access Memory (RAM): - The most common type of RAM is ‘double data rate 3’ (DDR3) memory modules. - High-performing systems use DDR4 memory modules - High-performing graphics cards often use DDR5 memory Memory Modules (Memory Cards): Small circuit boards that hold a series of RAM chips and fit into special slots on the motherboard. Dual Inline Memory Module (DIMM): A small circuit board that holds several memory chips Physical Memory: The amount of RAM actually sitting on memory modules in your computer Hard Drive: Platter: Several coated, round, thin plates of metal stacked on a spindle. Access Time: The time it takes a storage device to locate its stored data and make it available for processing, it’s the average total time it takes for the read/write head to locate the data on the platter and return it to the CPU for processing. Low-Level Formatting: Tracks containing sectors are created in the magnetized surface of each platter, setting up a grid-like pattern that identifies file locations on the hard drive. High-Level Formatting: This process establishes the catalog that the computer uses to keep track of where each file is located on the hard drive. Seek Time: This is the time it takes for the read/write heads to move over the surface of the disk, moving to the correct track Latency (Rotational Delay): Once the read/write head locates the correct track, it may need to wait for the correct sector to spin to the read/write head Head Crash: A stoppage of the hard drive that often results in data loss How the Data is Read: - When data is saved, a pattern of magnetized spots is created on the iron oxide coating of each platter - When the data is aligned in a specific direction they represent 1s (binary) and 0s when in another direction - When data is stored on the hard drive platter is retrieved, your computer translates these patterns into the data that you saved.
- A read/write head moves from the outer edge of the spinning platter to the center, to retrieve (read) and record (write) the magnetic data to and from the hard drive platter. Other Drives: Solid State Hybrid Drives (SSHD): A combination of both a mechanical hard drive and an SSD into a single device Optical Media: CDs, DVDs, and Blu-Ray (BD) Optical Drive: Data is read from a disc by laser beam and translated into data Lands: These are pits and non-pits translating 1s and 0s of the binary code that computers understand. Redundant Array of Independent Disks (RAID): A set of strategies for using more than one drive in a system. [RAID 0 & RAID 1 are the most popular options for consumer machines] Audio and Video Cards: Different Ports on Video Cards: 1. DVI Ports for digital LCD monitors 2. HDMI Ports for high-definition TVs, Blu-ray players, or gaming consoles 3. DisplayPort for digital monitors or projectors Video Memory: A video systems random access memory Graphic Double Data Rate (GDDR3) & (GDDR5): Video memory available on a graphics card Graphics Processing Unit (GPU):
