Computer Networking Fundamentals: Protocols and Hardware
Introduction to Computer Networks
A computer network is a collection of interconnected devices that can communicate with each other and share resources. These devices can include computers, servers, routers, switches, and other hardware. The primary purpose of a computer network is to facilitate communication and resource sharing among the connected devices.
Key Concepts of Computer Networks
1. Types of Networks
- Local Area Network (LAN): A network that covers a small geographical area, like a home,
Data Transmission and Multiplexing Techniques
Data Transmission Methods
Synchronization
Asynchronous Transmission: The issuer informs the receiver about the transmission instants. The receiver interprets the asynchronous information.
Synchronous Transmission: Transmission occurs at a constant cadence without needing character discrimination. This method aims to modulate the signal and adapt it to the channel, utilizing frequencies with the best channel response.
Modulation Techniques
Amplitude Modulation (AM): Modifies the wave’s amplitude (height)

XGBoost Algorithm
Which of the following is/are true about the XGBoost algorithm?
- It consists of decision trees as base learners.
- It is not the best choice for complex image recognition or NLP projects.
- Boosting is a technique that converts a collection of weak learners into a strong learner.
- If we use a CART tree as the base model, each leaf node is assigned a numerical score.
Which of the following is/are true about the XGBoost model?
- It is an additive model where the base functions are chosen from the

CDMA (Code Division Multiple Access)
Q. Working of CDMA
Ans. Code Division Multiple Access (CDMA) works by assigning a unique code to each user. Here’s how it works:
- Data Encoding: Each user’s data is multiplied by a unique spreading code, spreading the signal across a wider frequency band.
- Transmission: Multiple users transmit their encoded data over the same frequency band at the same time.
- Reception: The receiver uses the corresponding unique code to decode the signal, separating
