ARM CPU
ARM (advanced RISC Machine) micro architecture
-Widely used on smartphones and tablets
-ARM don’t make CPU but license the designs
RISC-Reduced instruction set computing
32 bit versus 64 bit
-32 bit cpu can address up to 4 GB memory
-64 bit CPU can address up to 16 Exabytes
Symmetric Multiprocessing (SMP)
-Providing multiple CPU sockets on the motherboard
-Usually a feature of server systems
Chip Level Multiprocessing (CMP)
-Each CPU contains multiple “cores”
-Each core works as a “more-or-less” independent CPU
System BUS
Front side bus between CPU and system memory
Expansion BUS
Input/output BUS between CPU and other processor
Bootstrapping (booting)
-CPU starts and initializes other components
-Occurs before operating system loads
-Controlled by PC firmware
BIOS
Basic inputing/output system
UEFI
Unified Extensible Firmware Interface
USB
-Plug-and-play interface
-Supplies enough power for small peripherals
-Versions and data rates
1.1-12mbps
2.0-480mbps
3.0-5 Gbps
3.1-10Gbps
Firewire
Similar to USB but not widely adopted on PCs
Data rate of 400 Mbps
6 pin and unpowered 4-pin connectors
Thunderbolt 2
20 Gbps over a MiniDP physical interface
Thunderbolt 3
40 Gbps over a USB-C physical interface
Personal Area Networks
Wireless communications enable short-range connections to peripheral and networks
Bluetooth
-up to 10m
-3 Mbps
-24 Mbps
Radio Frequency ID (RFID)
-Passive tags encoded with data
-Respond when scanned by an RFID reader
-Widely used for inventory management
