ALU: ALU: Arithmetic/Logic Unit (Lesson: Hardware)
   Contains the circuits that carry out instructions, such as mathematical and logical operations.
BIOS: BIOS: Basic Input/Output System (Lesson: Hardware)
   The BIOS stores information about your hardware configuration along with the boot program.
bus: bus (Lesson: Hardware)
   electrical pathways on the motherboard that connect the components.
BYOD: BYOD: Bring Your Own Device (Lesson: Hardware)
   A trend where employees are bringing devices to work and pressuring employers to support them.
cache: Cache (Lesson: Hardware)
   A temporary storage area for frequently accessed or recently accessed data; speeds up the operation of the computer; size measured in megabytes (MB)
chip: Chip, short for microchip (Lesson: Hardware)
   Developed in 1950s, it integrated multiple transistors into a single module called an integrated circuit.
circuit: Circuit (Lesson: Hardware)
   A circuit is created by combining transistors, and sometimes other components, in a manner that accomplishes a specific task
clock: Clock Speed (Lesson: Hardware)
   Speed of the processor’s internal clock, which dictates how fast the processor can process data; usually measured in GHz (gigahertz, or billions of pulses per second)
CPU: : CPU: Central Processing Unit (Lesson: Hardware)
   a group of circuits that perform the processing in a computer, typically in one integrated circuit called a microprocessor
CPU: components: CPU Components (Lesson: Hardware)
   The CPU is made up of many components. The main ones are Control unit, Arithmetic/logic unit (ALU), Registers, Cache, Clock speed
digital assistant: Digital Assistant (Lesson: Hardware)
   Streamlined interfaces like Apple’s Siri, Google Now, Amazon’s Alexa, and Microsoft’s Cortana
firmware: Firmware (Lesson: Hardware)
   programs and data from the computer manufacturer, including the boot process used to start the computer.
FSB: FSB: front front-side bus (Lesson: Hardware)
   The most important bus on a PC motherboard is the front front-side bus, or FSB. FSB speed is important and is typically listed with the specifications of a computer.
hardware: Hardware, computer (Lesson: Hardware)
   the tangible parts of a computer or digital device and typically includes support for processing, storage, input, and output.
Moore's law: Moore's Law (Lesson: Hardware)
   states that the number of transistors on a chip will double about every two years.
motherboard: Motherboard (Lesson: Hardware)
   the primary circuit board of a computer to which all components are connected, including the CPU.
multiprocessing: Multiprocessing (Lesson: Hardware)
   also called parallel processing, is processing that occurs using more than one processing unit to increase productivity and performance.
processing: Processing (Lesson: Hardware)
   carries out the instructions provided by software. Digital devices process bits of data into useful information and services.
questions: Self Study Questions(Lesson: Hardware)
   What have you learned?
raspberry: Raspberry Pi (Lesson: Hardware)
   Small, inexpensive motherboard containing entire computer systems used to build all kinds of electronic gadgets
registers: Registers (Lesson: Hardware)
   Hold the bytes currently being processed
ROM: ROM: Read-only memory (Lesson: Hardware)
   Read-only memory (ROM) provides permanent storage for data and instructions that do not change, such as firmware.
