Hardwere and Softwere
Hardware
physical components (that meke up computer)
external
storage device
external hard disk, memory sticks
peripherals
input devices
provide data -> computer
output /
processing (input) -> the outcome -> produced (computer)
internal c.
memori chips
mother board
video and soundcards
internal hard disk drive
cpu
brain/heart -> computer
set -> eletronic circuits
interprets/ executes instructions
fromed by:
cu (control unit)
controls flow data across: whole system -> by coording/ganzing: all the oprators
fetches: instructione(primary storage) --> interpret them -> sends commands -> hardwere (x compleat instructions)
alu (arithmetic and logic unit)
compleat // operations
ias(immediate access storage) -> registers
area -> data/ programs used(x pc)
4 steps (cpu) -> each machine language instruction recevided
1) fetching
cu extract -> instruction(main memory) -> stores it in temporary memory (ias)
I-Time (instruction time)
2) decoding
cu decodes instructions -> prepares them x execution
3) executing
alu carries out -> instructions
4) storing
results are sent to/ written down in memory
E-Time (execution time)
speed of cpu
dependes on:
clock speed
cores
caches
responsible -> performing 4 basic function
intput
processing
output
storage
Softwere
progrms, instructions ->that make possible (computer) -> to operate, compleat the tasks
system softwere
used -> run/ mantein computer includes
operating system
drives
utility softwere
file manager to save - dalate files
application softwere
used -> compleat specific tasks
the most
common types
word processing
presentation softwere
modelling softwere spreadsheets
data handling softwere database
web browser
desktop publishing/ video editing softwere
