Hardware And Software Flashcards
(47 cards)
an electronic data processing
device which
- accepts and stores data input,
- processes data input, and
- generates the output in a required
format.
Computer
Brain of the computer
Cpu
Performs data processing
operations
Cpu
interface between
hardware and software
Cpu
performs arithmetic and logical operations
Arithmetic and logic unit
temporary storage for instructions or data
within the processor
Registers Memory Unit
collects the result of
computations
Accumulator
keeps track of
where a given instruction or piece of data is
stored in memory
Address Register
temporarily holds
data taken from or about to be sent to
memory
Storage register
literally directs the entire computer system to carry out,
or execute, stored program instructions
Control unit
Important Functions of CPU in Instruction Cycle
Fetch, Decode, Execute, store
A memory space that serves as a buffer between the CPU and the
RAM.
Cache
the main printed circuit board (PCB) that connects all
the other components of the computer
Motherboard
mounting portion wherein
cpu are placed
Cpu socket
for the system’s main
memory, typically in the form of DRAM chips
Memory module slots
an interface between the CPU,
the main memory and other components
North bridge
controls the input and output
(I/O) functions
Southbridge
Slots for one or more hard drives to store files
Integrated drive electronics and serial advanced technology attachment
A read-only memory (ROM) chip,
which contains the firmware, or startup
instructions for the computer system
Bios chip
CPU Socket types
Pin, Land and Ball Grid
It is the space where
data and instructions are stored.
Memory(Random Access Memory
Three types of memory
Cache, Primary or Main memory and Secondary memory
contains
data for POST (Power on Self Test);
make sure that all the components are
functioning properly
ROM
the
computer’s temporary storage area so
that the CPU can access information
more easily
RAM
