Computer Network and Its Types

A network refers to a collection of interconnected nodes or entities that can communicate and share information with each other. These nodes can be computers, devices, or even people. Networks are used to facilitate the exchange of data, resources, or services among the connected entities.

Types of Networks

There are several types of networks, including:

• Local Area Network (LAN): LANs are typically limited to a small geographic area, such as a home, office, or campus. They are used for connecting devices within a relatively close proximity, often using Ethernet cables or Wi-Fi.
• Wide Area Network (WAN): WANs cover larger geographical areas and connect LANs over long distances. The internet is the most extensive example

Introduction

In the coming years, the manufacture of mirrors and glass will grow because the demand will be higher.

The process of making glass consists of melting certain substances until they solidify. This process dates back to a time before 2000 BC when glass was worked by hand using molds. Over time, glass has been used to make containers, decorative objects such as jewelry, and also in architecture and industry. At present, its recycling provides an important benefit to conserve the environment and reduce pollution.

Hypothesis

How viable is it to assemble a glass processing plant in Ecuador?

Ecuador does not manufacture glass; it is always imported. What they do in Ecuador is the processing of glass, such as:

• Polishing
• Vice-lane
• Stacking and

Moulds for Casting

Mould made of ceramic material e.g. sand particles, bound together with a BINDER which may be:

• Clay: 90% sand, 8% clay, 2% water - green sand mould.
• Thermosetting resin system - coat sand with two or more reactants which cure to form a resin (typically 1 - 2 parts binder to 100 parts sand):
  • Curing begins immediately components are combined, for a period of time after initial mixing the sand is workable and flowable to allow filling of mould - No bake systems.
  • Phenolic - urethane no bake is most common.
  • Curing occurs upon application of heat – heat cured binder system.
  • Liquid thermosetting binder and a catalyst are mixed with dry sand. Upon heating the catalyst releases acid which induces a rapid cure in 10 – 15 s. Pattern is

Network Security Essentials

Common Protocols and Ports

• TCP: Transmission Control Protocol
• SSH (TCP 22): Secure Shell
• Telnet (TCP 23): Insecure remote access
• HTTP (TCP 80): Hypertext Transfer Protocol
• HTTPS (TCP 443): Secure HTTP using SSL/TLS
• SSL/TLS: Encrypts web server communication with RSA and public/private key encryption
• FTP (TCP 21): File Transfer Protocol
• TFTP (UDP 69): Trivial File Transfer Protocol (no authentication or encryption)
• SNMP (UDP 161): Simple Network Management Protocol
• LDAP (TCP 389): Lightweight Directory Access Protocol
• NetBIOS (UDP 137/138): Network Basic Input/Output System
• Kerberos (UDP 88): Authentication protocol

Network Architecture

Internet → Router → Firewall → DMZ → Servers → Internal Network

• NAT/PAT: Network/Port

STONE MATERIALS: Stone materials are often used for construction because they are strong, durable and very resistant to weather conditions.

1.1. Extracting and processing stone: Stone is extracted from natural deposits. Some types exist as large blocks, such as marble and granite from quarries, which must be cut into smaller pieces. Other materials, such as gravel and sand, are aggregates.

1.2. Natural stone: -Limestone is a porous sedimentary rock. It is often used for sculptures and buildings, as well as for breakwaters in ports. -Limestone is used to produce lime and cement.

-Marble is a hard rock. Marble is cool to the touch and well-known for its resistance to compression and extreme weather conditions. Marble comes in a variety of colors... Continue reading "Stone Materials: Types, Properties, and Uses" »
