Lesson 1 Flashcards
Complex or carefully designed structure of somthing
Architecture
An electronic programmable device that can input, output, process and store data.
Computer
Refers to how a computer system is designed and what technologies it is compatible with.
Computer Architecture
Part of a computer system that consists of data or computer instructions in contrast to the physical hardware from which the system is built.
Software
Designed to do a specific task. It is a customized software.
Application Software
Designed to be able to make a computer run.
System Software
Operating Systems
- Memory Management
- Disks
- Peripherals
- Application Software
- Provides user interface
- Hardware/Software Installation
- File Management System
Collection of physical parts of a computer system.
Hardware
Hardware that can accept data.
Input Devices
Hardware that provides data output.
Output Devices
Hardeare that process data to be able to transform into information.
Ex. RAM, CPU
Processing Devices
Hardware that can store data.
Storage Devices
A medium to allow communications between computers.
Communication Devices
Hardware Components
- Main Memory
- Secondary Storage
- Input and Output Devices
- CPU
RAM or Random Access Memory, needs electrical power to maintain information.
Main Memory
Auxiliary Memory, a non-volatile memory (does not store data when the device power is down) that is not directly accessible by the CPU, not accessed via input/output channels.
Secondary Storage
Carries out instructions of a computer program by performing the basic arithmetic, logical, control and input/output operations specified by the instructions.
Central Processing Unit (CPU)
A component of CPU that directs the operations of the processor. It tells how to respond to a program instruction.
Control Unit (CU)
Digital circuit used to perform arithmetic and logic operations.
Arithmetic Logic Unit (ALU)
Frequency and indicators of processor’s speed. Clock cycles per second SI unit hertz (Hz), kilohertz (kHz)
Clock Rate
