boring programming Flashcards
Imperative programming?
Where we tell the computer what to do
Add subtract store and load LMC instructions (3 letters(
ADD
SUB
STA
LDA
LMC branch instructions
BRA - ALWAYS
BRZ - IF ZERO
BRP - IF POSITIVE
LMC PRINT, READ INSTRUCTIONS
INP
OUT
LMC end program instruction
HLT (halt)
LMC DAT instruction what is it
It’s normal asm like data in the bss/data section
notify assembler it’s a static piece of data like a string in the exe
LMC where are labels put
Before any instruction
Direct vs immediate addressing
Direct is normal like pointer deference
Immediate is not really addressing just means load the actual data not the address (deferencing the pointer is just getting the pointer int value
Indirect vs indexed addressing
Indirect is double pointer deferenencing (ie LDA 6 would mean load the value from the pointer which the pointer is at memory location address 6)
Indexed is when you have an index register and then can increment it etc
What tags are needed for a HTML page with a title, a heading and some paragraph
Head,body,title,h1,p
What are how use the IMG tag HTML

with <li> uses bullet points</li>

getElementById(“…”).innerHTML
How to put a “page says” message in browser in js

What is a heuristic approach to problem solving (2)
Educated guess approach (1)
Which leads to a “good enough” result
Example of heuristics when making a decision about if to cross a busy road (3)
Any 3 of
We dont get data (1) about all vehicle speeds (1)
We scan the data for which is most likely to be useful (1)
And make a judgement based on experience (1)
MDR vs MAR
MDR is the actual instruction fetched
MAR is the current address instruction
What bus and what gets sent down when loading/storing in LMC
CONTROL BUS
Read or write signal
What is the memory management where it’s split into chunks
PAGING
What happens when a search engine indexes a page (3)
web crawler (1) transverses web (1) takes each word in the document and adds an entry (1)
Why does RISC have less power consumption
less transistors
