Operating Systems and Networking Concepts

The representation of information using discrete values, like 0s and 1s in binary.

The representation of information using continuous values, like a dial on a radio.

A numbering system using only the digits 0 and 1.

A way to represent logical relationships, such as AND, OR, and NOT.

The force that pushes electrons through a circuit, measured in volts.

The flow of electrons through a circuit, measured in amps.

The opposition to the flow of current, measured in ohms.

Small electronic components that can act as switches, controlling the flow of electricity.

A collection of interconnected networks that allow computers around the world to communicate with each other.

A set of networking protocols that define how data is transmitted and received over the Internet.

Deals with the physical transmission of data between devices on the same network.

Responsible for routing packets from one network to another across the internet.

Handles data transmission between applications on different computers.

Provides services for applications to interact with the Internet. Examples include HTTP, FTP, and email.

A protocol used by devices to automatically obtain an IP address from a network.

A protocol used to translate domain names (like google.com) into IP addresses.

A programming paradigm that organizes code around objects, which have data (attributes) and actions (methods).

A program that translates high-level code into machine code that the computer can execute.

A program that executes high-level code line by line, without translating it all at once.

A program that runs in the background, performing tasks without direct user interaction.

A software layer that provides a standard way for programs to interact with the operating system.

A protected environment where applications run, isolated from the underlying operating system.

A privileged environment where the operating system runs, with full access to system resources.

A virtual address space that allows programs to access more memory than physically available, by swapping data between RAM and disk.
