Algorithmics
- Definition: Algorithmics is the study of algorithms, which are step-by-step procedures for solving problems or achieving a specific task.
-
Types of Algorithms:
- Recursive algorithms: break down problems into smaller instances of the same problem.
- Dynamic programming algorithms: solve problems by breaking them down into smaller subproblems.
- Backtracking algorithms: find a solution by exploring all possible solutions.
-
Algorithm Analysis:
- Time complexity: measures the number of steps required to complete an algorithm.
- Space complexity: measures the amount of memory required to complete an algorithm.
-
Algorithm Design Techniques:
- Divide and Conquer
- Greedy Algorithm
- Dynamic Programming
Computer Networks
- Definition: Computer networks are collections of interconnected devices that communicate with each other to share resources and exchange data.
-
Network Topologies:
- Bus topology: a single cable connects all devices.
- Star topology: devices connected to a central device.
- Ring topology: devices connected in a circular configuration.
-
Network Protocols:
- TCP/IP (Transmission Control Protocol/Internet Protocol): a suite of protocols for communicating over the internet.
- HTTP (Hypertext Transfer Protocol): a protocol for transferring data over the internet.
- FTP (File Transfer Protocol): a protocol for transferring files over a network.
-
Network Architectures:
- Client-Server architecture: clients request resources from a central server.
- Peer-to-Peer architecture: devices act as both clients and servers.
Code
- Definition: Code refers to the written instructions that a computer can execute to perform a specific task.
-
Programming Paradigms:
- Imperative programming: focuses on describing how to perform a task.
- Object-Oriented Programming (OOP): organizes code into objects that interact with each other.
- Functional programming: focuses on evaluating expressions to produce a result.
-
Programming Languages:
- Low-level languages: close to the machine language, e.g., assembly language.
- High-level languages: farther from machine language, e.g., Python, Java.
-
Code Organization:
- Modularity: breaking down code into smaller, reusable modules.
- Abstraction: hiding implementation details to focus on essential features.
