Study Notes
Operating System Architectures
- Modern operating systems are predominantly 64-bit architectures.
- Older operating systems may be 32-bit.
- CPU architecture dictates bit capacity (32-bit or 64-bit).
Bit Architecture Details
- 32-bit processors can access ~4 billion values.
- 64-bit processors can access an extremely large amount of data (264).
- 32-bit OSes can access 4 gigabytes of memory.
- 64-bit OSes can access significantly more memory (up to 17 billion gigabytes theoretically, but real-world limits apply).
- Application compatibility matters: 32-bit apps can't run on 64-bit OS; reverse is true.
- 32-bit applications installed in 'Program Files x86', 64-bit apps in 'Program Files'.
- Hardware drivers must match OS bit type (32-bit drivers for 32-bit OSes, 64-bit for 64-bit OSes).
- x86 abbreviation for 32-bit (Intel 8086 processor).
- x64 abbreviation for 64-bit.
System Type Checking in Windows
- Check system type in Windows Control Panel > System settings.
- Shows system type (like "64-bit operating system with an x64-based processor")
ARM Architecture
- ARM (Advanced RISC Machine) architecture is a different processor design.
- ARM Limited created the design specifications.
- ARM-based CPUs are efficient and lower power consumption.
- Suitable for mobile devices and IoT.
- ARM architecture capabilities are expanding and blurring the space between traditional 64-bit and ARM-based OSes.
CPU Components and Cores
- CPUs are complex systems with many components; the core is the main processing unit.
- Multi-core: modern CPUs commonly have more than one core. (Dual-core, quad-core, multi-core).
- More cores in modern CPUs.
- Caches speed up data transfer to and from the CPU (dedicated per core or shared per core)
- CPU's contain memory controllers, graphics processors – possibly built into one unit.
Hyper-Threading Technology (HTT)
- Hyper-Threading Technology (HTT) makes a single CPU core appear as multiple cores.
- Increases the throughput of processes approximately 15-30%.
- Modern OSes generally support HTT.
Virtualization
- Hardware virtualization allows multiple operating systems to run on a single system.
- Enabled in CPU hardware for efficiency.
- Intel Virtualization Technology (VT) or AMD Virtualization (AMD-V) should be checked for compatibility in BIOS.
