Study Notes
Key Concepts in Computer Architecture
-
Moore's Law: Describes the exponential growth in the number of transistors on CPU chips, indicating rapid improvements in computing power.
-
CPU Execution Stage: The stage in a machine cycle where the CPU carries out instructions is known as the Execute stage.
-
Memory Types: Computers utilize both volatile memory (temporary storage) and nonvolatile memory (permanent storage) to manage data.
System Performance and Usage
-
Monitoring CPU Usage: Check the Performance tab in the Task Manager to effectively assess CPU usage and performance.
-
RAID: Refers to a set of strategies for utilizing multiple drives in a system, enhancing data management and redundancy.
-
Fast Memory: Cache is identified as the fastest type of memory available in a computer, significantly speeding up data access.
Hardware Specifications
-
Video Memory Types: GDDR5 and GDDR3 are classifications of video memory, impacting graphics performance in computing.
-
MIDI Interface: Essential for musicians, a MIDI interface allows for the seamless recording and production of music with digital instruments.
-
SSD vs. Hard Drives: Solid State Drives (SSDs) are favored over traditional hard drives due to their superior data transfer speeds.
System Maintenance and Reliability
-
Windows Reset: Perform a Windows Reset before donating a computer to ensure personal data is removed and the system is restored to its factory settings.
-
Restore Points: Windows saves "restore points" to enable users to revert their system back to a previous state before new software installations.
-
System Restore vs. Refresh: When facing unreliable Windows behavior, conducting a System Restore is recommended prior to performing a Windows Refresh for troubleshooting.
General Considerations
-
Value of Desktop Systems: Desktop computers generally provide better value than lightweight, portable computers due to performance and upgrade potential.
-
Limitations on RAM: While modern computers can support significant amounts of RAM, there are limits to how much can be installed, contrary to common belief.
