1 Types and components of computer hardware
Hardware and software
Hardware
(parts of a comp that you can touch)
storage devices
e.g. SSDs, HDD, optical drives
(keeps data and the software)
backing storage
same unit of memory
internal
CPU
(brain of comp)
ALU
(logical operations)
CU
(manage the various components of the comp)
registers
(hold current processing data)
clock
(determines speed)
internal memory
RAM
(stores data that is being used)
ROM
(stores permanent data)
external
input and output devices
i e.g.: keyboard, mouse
e e.g.: monitor, speaker
(physical parts)
Software
(tells the comp what to do)
application and system
system (2 main parts): OS and utilities
(system: the software that a comp is needed to operate)
system(all parts): compilers linkers, OS, utilities, DDs
OS
GUI
CLI
command syntax
Dialogue-based interface
Gesture-based interface
e.g.Windows
app e.g.: Word processors, spreadsheets databases
off-the-shelf software
comp language
Analogue and digital data
comp
understands
digital
bit/binary code
(comp only understand electrical signals being turned on or off)
transistors
comp convert between both
ADCs and DACs
ADC: sampling and quantization
input and output
humans hear sound data in analogue method
(A: continuous vaules)
(D: separate vaules)
Types of comps
desktops
external devices
peripherals
fixed position
Laptop
portable version of desktop
included integrated devices
tablet
handheld
phones
apps
phablets
phone + tablet
AI
robots/robotics
