Study Notes
CPU Architectures and Technologies
- Modern operating systems use 64-bit architecture CPUs, but 32-bit systems still exist.
- 32-bit CPUs can access roughly 4 billion values, whereas 64-bit CPUs can access a vastly greater number.
- 32-bit systems have a maximum memory access of ~4GB, while 64-bit systems can theoretically access far more extensive memory ranges. However, practical maximums exist for OS usage.
- 32-bit software, often labeled as x86, is a type of software compatible with the Intel 8086 line of processors. 64-bit software is called x64.
- 32-bit OSs can only run 32-bit applications, while 64-bit OSs can run both 32-bit and 64-bit applications.
- Application installation locations differ between 32-bit and 64-bit systems (Program Files x86 for 32-bit, Program Files for 64-bit).
ARM Architecture
- ARM architecture is a type of CPU architecture, most commonly used in mobile devices and IoT devices.
- ARM processors were designed by ARM Limited, and third parties develop the hardware using the ARM specifications.
- ARM processors are known for their efficiency and low power consumption.
CPU Cores and Caching
- CPUs are not monolithic; they have multiple components, including cores (processing units) and caches (high-speed storage).
- Multi-core processors, with several cores in a single package (dual-core, quad core, etc.) are common.
- Cores often have dedicated caches, or share them. Caches speed up CPU operations by storing frequently accessed data.
Hyper-Threading Technology (HTT)
- HTT allows a single physical CPU core to function as multiple logical CPU cores.
- This increases the throughput of the CPU processes, ranging from 15% to 30%.
- Modern operating systems support Hyper-Threading.
CPU Virtualization Technologies
- CPUs can support virtualization, allowing multiple operating systems to run concurrently on a single computer.
- Intel Virtualization Technology (VT) is for Intel processors, while AMD Virtualization (AMD-V) is for AMD processors.
- Enabling Virtualization through BIOS settings is required by some virtualization software.
Checking System Type
- Windows System settings (Control Panel) display the system type (32-bit or 64-bit).
- Determining the system type is valuable in matching hardware, software, and drivers.
