Biology Exam Revision: Key Concepts in Physiology and Ecology
Factors Affecting Photosynthesis Rate
Point: Photosynthesis rate increases as light intensity, $\text{CO}_2$ concentration, and temperature increase—up to an optimum point.
Explanation:
- Light provides the energy for the light-dependent reactions.
- $\text{CO}_2$ is a necessary substrate for glucose synthesis (Calvin cycle).
- Temperature affects the activity of enzymes within the chloroplasts.
Example: In experiments, the rate of oxygen release (or $\text{CO}_2$ uptake) rises with light until a plateau
Origins and Outbreak of World War I
Causes of World War I
I. Intense Global Rivalry
The distribution of global power led to tremendous rivalry between major powers. These confrontations were intensified by the complex system of alliances and enmities established in Europe between 1870 and 1890.
II. The Armed Peace (1890–1914)
From 1890, the German Empire, led by Kaiser William II, launched an aggressive expansionist policy. William initiated a significant program of investment in arms and naval fleets and actively intervened in overseas

Structure of the Telephone User Network
Sections of the User Network
The user network is divided into three main parts: the main network, the distribution network, and the dispersion network.
The user network encompasses the path from the central plant’s main distribution point until the connection reaches the user’s telephone equipment. These stages are:
- Outdoor Line: This section covers the path from the central terminal to the distribution box. This connection typically uses high-capacity cables. The outdoor line is further divided into
Input and Output Devices Plus Operating System Functions
Input Devices
💻 Input devices are hardware components that allow users to send data and control signals to a computer.
Classification and Use
Input devices can be broadly classified based on the type of data they input:
| Classification | Example Devices | Primary Use |
|---|---|---|
| Human Data Entry | Keyboard, Mouse, Microphone | Manual data entry, text, commands, and real-time control. |
| Source Data Automation | Scanner, Digital Camera, Magnetic Stripe Reader | Capturing data directly from the source without human transcription. |

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
