Network Hierarchy: Core, Distribution, and Access Layers
Network Hierarchy Design
Core Layer
The Core Layer consists of the biggest, fastest, and most expensive routers with the highest model numbers. The Core Layer is considered the backbone of networks. Core Layer routers are used to merge geographically separated networks. These routers move information on the network as fast as possible. Core layer switches also operate to switch packets as fast as possible.
The core layer provides fast transport between distribution switches within the enterprise campus.

GSM Protocol Architecture
The GSM Protocol Architecture is a three-layer model designed to handle communication between the Mobile Station (MS) and the Core Network. These layers roughly correspond to the bottom three layers of the OSI model: Physical, Data Link, and Network.
Three-Layer Architecture
Layer 1 (Physical Layer)
This layer handles the actual radio transmission. It manages functions like GMSK modulation, channel coding, and the creation of the 0.577 ms bursts described earlier. It operates

Digital Logic Design and Information Representation
Unit 1: Information Representation
Information representation is the method used by computers to store, process, and transmit data in a form that can be understood by electronic systems. Since computers are digital devices, all information such as numbers, characters, images, and instructions is represented internally using binary digits (0 and 1). These binary values correspond to electrical signals like ON and OFF.
Different coding techniques are used to represent various types of information efficiently
