Introduction to Computers
This device is used to enter data into the computer, like a keyboard or mouse.
What is an Input Device?
This type of component is physical, can be seen and touched, like keyboard, CPU, and monitor.
What is Hardware?
This type of logic depends on both current input and past output (memory).
What is Sequential Logic?
This component is known as the brain of the computer and performs processing.
What is CPU?
This component acts as a bridge between the CPU and external devices like keyboard and printer.
What is an I/O Interface?
This component stores data permanently, even when the power is turned off.
What is Secondary Memory (Storage)?
This type of component is a set of instructions that tells the computer what to do.
What is Software?
This signal controls when changes happen in synchronous sequential circuits.
What is Clock Signal?
This unit in the CPU performs arithmetic operations like addition and subtraction.
What is ALU?
This interface is commonly used to connect devices like keyboard, mouse, and pen drive.
What is USB?
This type of memory loses its data when the power is turned off.
What is RAM (Primary Memory)?
This logic gate gives output TRUE only when both inputs are TRUE.
What is AND Gate?
This model represents a system with states, inputs, and transitions between states.
What is Finite State Machine (FSM)?
This unit controls and coordinates all operations of the CPU and ensures instructions are executed in order.
What is Control Unit?
This interface is used to transmit both audio and video from a computer to a monitor or projector.
What is HDMI?
This type of computer is small, built inside devices, and performs a specific task automatically.
What is an Embedded Computer?
This logic gate gives TRUE output only when exactly one input is TRUE.
What is XOR Gate?
In this FSM model, output depends only on the current state and not on input.
What is Moore Model?
This cycle consists of three steps: fetching an instruction, decoding it, and executing it.
What is Fetch-Decode-Execute Cycle?
This hardware component allows a computer to connect to a network and communicate with other devices.
What is NIC (Network Interface Card)?
This transmission method sends data continuously using a shared clock signal between sender and receiver.
What is Synchronous Transmission?
This type of digital circuit gives output based only on current input and does not depend on past inputs.
What is Combinational Logic?
This design approach starts from smaller components and builds up a complete system.
What is Bottom-Up Design?
This is the fastest type of memory located inside the CPU, used for immediate data access.
What are Registers?
This data transfer approach allows devices to send data directly to memory without CPU involvement.
What is Direct Memory Access (DMA)?
