What is the hardware?
These are the 4 fundamental components of the von Neumann machine.
What are ALU, CU, I/O, and memory.
This type of memory is volatile, temporarily stores data and instructions currently in use, and loses its contents when the power is turned off.
What is RAM?
Data travels in one direction along one wire
What is serial simplex data transmission?
A type of AI that uses training data.
This is one of the type of user interfaces that OSs can have
What is CLI or GUI?
These are the three busses with their directionality.
What are control (uni), data (bi), and address (uni)?
This non-volatile memory chip stores the firmware that starts up the computer and performs the POST process.
What is ROM?
This is how data is protected against unauthorized viewing during data transmission.
What is encryption?
These are two of the three qualities of a robot.
What are 1) programmable, 2) has a mechanical structure, and 3) can sense its surroundings.
This is a function of an OS that allocates RAM to each program
What is memory management
This is where results of mathematical operations go
What is the accumulator?
This storage device uses flash memory, has no moving parts, and is generally faster and more durable than a traditional HDD.
What is SSD?
These are two ways that data can be validated during transmission.
What is parity bit and checksum?
(ARQ is OK)
These are two advantages of robots.
Robots can work in dangerous environments and can do repetitive tasks?
This is the 2 things that file management does
What are assigns hierarchical folder structures and assign file access?
This is what happens to each register during one cycle of FDE.
What is
[MAR] <-- [PC]
[PC] <-- [PC] + 1
[MDR] <-- [[MAR]]
[CIR] <-- [MDR]
[ACC] <-- ALU results
What is optical storage?
This is what's in a data packet.
What are sender/receiver IP address, packet number, payload, and error checking?
These are three applications of autonomous systems
What are agriculture, industry, weather, entertainment?
Multitasking wouldn't be possible without this thing that allows important computer operations to be done immediately.
What is an interrupt?
When writing data to memory from the CPU, this is what happens to the registers and addresses.
What is
address to be written to is stored in MAR
data to be written stored in MDR
address sent along address bus
data sent along data bus
write signal sent along control bus?
What are capacitive, resistive, and thermal?
This describes how asymmetric encryption works.
What is the receiver sends a public key, the sender uses the public key to encrypt the data, the receiver uses their private key to decrypt the data?
These are the 4 components of an expert system.
What are user interface, rules base, knowledge base, and inference engine?
