Systems Architecture - ANS The structure, interaction, and technology of computer
components.
CPU, Primary Storage, Secondary Storage, I/O units, System Bus - ANS What are the
Computer Hardware components?
CPU - ANS A general-purpose processor that executes all instructions and controls all data
movement in the computer system.
Primary Storage - ANS High-speed storage in a computer system that holds currently running
programs and data immediately needed by these programs.
Secondary Storage - ANS System devices that provide large-capacity and long-term data
storage.
I/O Unit - ANS Devices that perform external communication functions.
System Bus - ANS The internal communication channel connecting all hardware devices.

, Compactness, Accuracy, Range, Eace of Manipulation, Standardization. CARES - ANS What
are the Goals of data representation?
Describes the number of bits used to represent a numeric value. It has a limited range of values
that can it represent. - ANS Compactness/trade-off
The degree to which the result of a measurement conforms to the correct value. It can be
achieved by balancing performance and cost. - ANS Accuracy/trade-off
The range of numbers available to use uses more data slower. The more compact a device with
a small arrange the more affordable it will be. - ANS Range/trade-off
How easy it is for the computer to process the data. More complex devices require more time
to perform functions. - ANS Eace of Manipulation/trade-off
Ensures correct and efficient data transmission. The risk of losing functionality between
devices. - ANS Standardization/trade-off
Control unit, ALU, registers - ANS CPU components
Control Unit - ANS Responsible for moving data, accessing instructions, and controlling the
arithmetic logic unit.
ALU - ANS Contains circuitry for performing computation, comparison, and logic instructions.
Registers - ANS Internal storage locations in a CPU. Each is capable of holding a single
instruction or data item instruction and instruction sets
