Rigid Couplings
Rigid couplings connect machine shafts that are perfectly aligned. They offer advantages such as easy mounting and dismounting, few spare parts, and economical operation. However, they are not suitable for applications with misalignment or vibration.
- Sleeve couplings: Join two shafts with pins and screws, providing friction-based connection.
- Flange couplings: Attached with screws, offering easy assembly and disassembly.
Flexible Couplings
Flexible couplings accommodate misalignment

Introduction to Network Design and VLANs
The Importance of Network Configuration
Efficient communication within local area networks (LANs) and wide area networks (WANs) relies heavily on properly configured interconnect devices. These devices ensure seamless connectivity and data exchange between various network components.
This document delves into the concept of virtual network configuration, specifically focusing on Virtual Local Area Networks (VLANs).
Understanding VLANs
A VLAN is a method for creating

RAM (Random Access Memory)
RAM temporarily stores the running configuration file and routing table during operation. It loses its contents when the router is powered off or restarted.
ROM (Read-Only Memory)
ROM permanently stores the bootstrap program and basic diagnostic software used during the boot sequence. It retains its contents even when the router is powered off.
NVRAM (Non-Volatile Random Access Memory)
NVRAM stores the startup configuration file, which is loaded into RAM during

Compressor
Compressors are machines that suck air from the atmosphere and compress it to a high pressure. This compressed air is then used to power various pneumatic tools and equipment. The movement of the compressor is achieved through belts and pulleys.
Types of Compressors
A) Piston Compressors
Piston compressors work by drawing in air through a suction valve as the piston moves downward, driven by the crankshaft. The air is then compressed and deposited in a high-pressure zone thanks to the exhaust

Incorporation of a Solar Cell
A solar cell is formed from a wafer of semiconductor material, such as silicon, on which boron (a trivalent impurity) is spread to create a P-region and a thin layer of phosphorus (a pentavalent impurity) is spread to create an N-region, forming a PN junction. To improve performance, the sun-facing side undergoes surface treatment to reduce reflection. A metal mesh on this surface provides electrical connection while maximizing sun exposure. This mesh consists of fine
