4. Definisi
● Computer hardware is the collection of
physical elements that constitutes a computer
system.
● Refers to the physical parts of a computer
– monitor, mouse, keyboard, computer data storage,
hard drive disk (HDD), system unit (graphic
cards, sound cards, memory, motherboard and
chips), etc.
● Physical objects => can be touched.
● http://en.wikipedia.org/wiki/Computer_hardware
5. Pengertian
● Sekumpulan elemen fisik yang menjadi
bagian sistem komputer.
● Merujuk pada bagian fisik komputer seperti:
– monitor, mouse, keyboard, computer data storage,
hard drive disk (HDD), system unit (graphic
cards, sound cards, memory, motherboard and
chips), etc.
● Objek fisik => Bisa disentuh, dilihat.
8. Input
● Process of entering data and programs in to
the computer system.
– Computer is an electronic machine like any other
machine which takes as inputs raw data and
performs some processing giving out processed
data.
– Input unit takes data from user to the computer in
an organized manner for processing.
9. Storage
● Process of saving data and instructions
permanently.
– Processing speed of CPU is so fast. Data has to be
provided to CPU with the same speed. Data is
first stored in the storage unit for faster access
and processing.
● Function
– All data and instructions are stored before and
after processing.
– Intermediate results of processing are also stored
10. Precessing
● The task of performing operations like
arithmetic and logical operations.
– (CPU) takes data and instructions from the
storage unit,
– makes all sorts of calculations based on the
instructions given and the type of data provided.
It is then
– sent back to the storage unit.
11. OUTPUT
● Process of producing results from the data for
getting useful information.
– Produced by the computer after processing.
– Kept (stored) somewhere inside the computer
● before being given to user in human readable form.
● further processing
12. Control
● The manner how:
– instructions are executed and operations are
performed.
● Performed by control unit.
13. Functional Unit
● To carry out the operations, the computer
allocates the task between its various
functional units.
– arithmetic logical unit
– control unit.
– central processing unit.
14. Arithmetic Logical Unit (ALU)
● Perform actual processing of the data and
instruction when required.
● The major operations:
– addition, subtraction, multiplication, division,
logic and comparison.
● After processing, the output is returned back
to storage unit for:
– further processing or
– getting stored.
15. Control Unit
● Responsible for co ordinating various
operations using time signal.
● Determines the sequence in which computer
programs and instructions are executed.
16. Central Processing Unit
● Integration of ALU and CU
● Brain of any computer system.
– Takes all major decisions,
– makes all sorts of calculations,
– directs different parts of the computer functions
– by activating and controlling the operations.
