What is data? Info stored as binary inputs\/outputs (numbers, letters, commands)
What is a bit? describes the size of data, each individual number is a bit
What is a byte? used to describe large binary numbers, one byte=8 bits
What is serial data transfer? uses one wire for input and output, data is transferred one bit at a time
What is parallel data transfer? uses separate wire for each bit, allows all bits to transfer in one clock pulse
What is the benefit of parallel over serial data transfer? takes less time to transfer large data
What is the purpose of a register? stores AND transfers data from one circuit to another
What type of flip flops do registers use? JK or D flip flops
What are two types of registers? Storage and shift
What is the purpose of a storage register? Temporarily store data until its needed or transferred out
What is the purpose of a shift register? transfer data from one circuit to another, uses both serial and parallel transfer
What is the purpose of a 4 bit storage register? designed to temporarily store 4 bits of binary data
How many flip flops are used in 4 bit storage register? What kind of flip flops? 4 D flip flops
What is the purpose of a 4 bit shift register? designed to transfer 4 bits of binary data from one circuit to another
What type of transfer is used when mode control is HIGH in 4 bit shift register? Parallel
What type of transfer is used when mode control is LOW in 4 bit shift register? Serial
How is shift right set up in 4 bit shift register? Circulate
How is shift left set up in 4 bit shift register? Load
Does shift right use serial or parallel transfer? Serial
In what type of circuits is shift left used? Registers that perform math
What is the purpose of 8 bit shift register? transfer 8 bits of binary data from one circuit to another
Which type of data is shifted manually with no fixed time relationship? Asynchronous
What type of data is shifted automatically with a fixed time relationship? Synchronous (controlled by clock pulse)
Serial inputs in 8 bit register are synchronous or asynchronous? Synchronous, controlled by clock
Parallel inputs in 8 bit register are synchronous or asynchronous Asynchronous, controlled by HIGH pre enable
What is the purpose of a 64 bit memory circuit? capable of storing 64 bits of data until needed
What is a complete piece of digital information known as? word
What is an address? where words are stored, used to store new data and locate old data
What is the process of transferring data to memory? Writing
What is the process of transferring data out of memory? Reading
What is ROM? Read Only Memory, used when identical data is needed each time
What is a form of volatile memory? RAM
What is RAM? Random Access Memory, info\/instructions that go into and out of memory
What is a form of non volatile memory? ROM
What is non-volatile memory? Data retained when power is removed
What is volatile memory? Storage that is wiped clean when power is cut off from a device
What type of flip flop in which state do counters use? JK flip flops in toggle
When does the B flip flop change state in a counter? When A changes from 1 to 0
What is modulus? the number of counts a counter can produce
How is modulus calculated? 2^N where N = number of flip flops
Which type of counter doesnt require a clock pulse? Asynchronous
Where is input applied to in asynchronous counter? To the clock
When is input applied in a synchronous counter? When clock is high
Each flip flop does what to the output in counter? Each flip flop divides input in half
What 4 functions can an adder perform? Add, subtract, divide, multiply
How is subtraction performed by adder? One input is inverted and then added to second input (input is turned negative)
How is division performed on adder? series of subtractions, counter counts how many times it must subtract two numbers to reach 0 (one input is inverted)
How is multiplication performer on adder? Series of additions
Mod _<\/em> is required for decimal numbers? Mod 10
What is the purpose of a ripple counter? count pulses in binary
How many flip flops are used in ripple counter? What kind are they 4 JK flip flops with clear
What does CLEAR input do in ripple counter? Clear HIGH= counter operates normallyClear LOW= counter is reset to 0000, overrides input to clock
Which input allows counter to operate in different Mods (ripple counter)? Clear
What is free run op in counters? Counter counts up to max or down from max and then starts count over
What is single step op in counters? Counter counts up to max or down from max and stops and input pulses are disabled
In up\/down counters what does enablenot do? Enablenot LOW allows counter to function, HIGH disables counter
In up counters what does loadnot do? allows counter to start counting at various mods\/different numbers, load LOW starts count over
What type of gate does a down counter use? NOR
What does loadnot do in down counters? determines what number is loaded into counter, sets to number on inputs A-D
Should the Upnot\/Down switch be at ground or 5V in down counter? 5V<\/p>\n\n\n\n
