Revenue, Profit, and Tax Calculations
Revenue (R(x)): R(x) = FC + VC(x) + PBT
Profit After Tax (PAT): PAT = PBT – CT
Corporate Tax (CT): CT = PBT × CTR / 100
Profit Before Tax (PBT): PBT = PAT / (1 – CTR)
The Purchasing Cycle

- Value Analysis: Determining the lowest cost way to satisfy the request.
- Supplier Selection: Evaluating prices, delivery times, quality, and other factors.

Data Link Layer Protocols: Services, Framing, and Error Control
Data-Link Layer Service Categories
Describe the three possible categories of services provided by the data-link layer:
Unacknowledged Connectionless Service
- This service is appropriate when the error rate is very low, so recovery is left to higher layers.
- It is also appropriate for real-time traffic, such as voice, where late data are worse than bad data.
Acknowledged Connectionless Service
- No logical connections are used, but each frame sent is individually acknowledged.
- Thus, the sender knows whether
Fundamentals of Chemical Elements and Bonding
The Periodic Table of Chemical Elements
All chemical elements are arranged in order of increasing atomic number (Z) in a table called the Periodic Table, in a way that reflects their atomic structure.
The elements are arranged in:
- Seven horizontal rows called periods.
- Eighteen vertical columns called groups.
The periods are classified by length:
- Short periods: The first period (containing two elements: hydrogen and helium) and the two following periods (each with eight elements).
- Long periods: The remaining
Auxin and Ethylene: Regulators of Plant Growth and Signaling
Phytohormones: Definition and Signaling Principles
What is a Phytohormone?
A phytohormone is a naturally occurring organic molecule produced in plants that acts at low concentrations to regulate growth, development, and responses to environmental stimuli.
- They are signal molecules that coordinate physiological processes such as cell division, elongation, differentiation, flowering, and stress responses.
- Examples include auxins, cytokinins, gibberellins, abscisic acid (ABA), ethylene, brassinosteroids,

Types of I/O Devices
Block Devices
Store data in fixed-size blocks. Data transfer happens in blocks (e.g., SSD).
Character Devices
Handle a stream of characters with no block structure (e.g., Keyboard, Mouse). They do not support seek operations.
Block vs. Character Devices
Block devices support random access and block-level operations, while character devices operate in a stream and cannot seek.
I/O Communication Methods
