The presentation addresses the major benefits of implementing a wireless local area network (WLAN) for a company, including increased mobility within the network, lower installation costs compared to running cables, easier network modifications, and improved disaster recovery capabilities. However, the presentation also notes some disadvantages of WLANs, such as potential radio signal interference, security risks from broadcasting the wireless signal openly, and unresolved health concerns regarding low-level radio frequency emissions.Wireless Local area networking power point

A wireless local area network (WLAN) uses radio waves to transmit and receive data over the air, minimizing the need for wired connections. A basic wireless network can be set up between two PCs with wireless cards in a peer-to-peer configuration. Larger wireless networks use access points connected to a wired network to connect multiple clients and extend the range of the network. Factors like access point placement, use of extension points or directional antennas can help ensure clients stay connected as they roam across coverage areas. While wireless networks provide mobility and flexibility, their setup and maintenance require additional hardware, have security limitations, and may have lower bandwidth compared to wired networks.Internetworking

This document provides an overview of networking concepts and describes how data is exchanged between network devices. It explains that a hub operates at the physical layer, broadcasting all traffic to all connected ports so that all devices share the same bandwidth and collision domain. The document also introduces switches and routers, describing their roles in selecting the path that data travels and how they allow for separate collision domains and bandwidth allocation. It provides examples of how data is encapsulated as it passes through the different layers of the OSI model.DescriptionYou were selected to design a small peer-to-peer ne.docx

Description
You were selected to design a small peer-to-peer network for a new facility which has six油computers and油a networked printer. Each desk computer油must have a wired network connection.油 The rooms are to have wireless access for mobile devices.
For this assignment, utilize the油Gliffy油(Links to an external site.)Links to an external site.油software application to create a basic network diagram depicting a star topology with a switch as the central communications node. The focus here is on the network communications equipment for this LAN.油 Include only that equipment and end node devices on the network diagram. There is no need to draw out the layout of the physical space.
In addition to providing a network diagram, you must also provide a short essay that describes the details of the LAN equipment that is being used and the connections. In the essay, be sure to explain why each device is positioned where it is.
Also, briefly state any assumptions you've made about the kind of work being done, the demands the personnel in the office will put on the network, how they'll use it, and how that influenced your design. For example, if the business that uses the LAN is a small video-based news streaming service, they will probably need more performance from both their network and ISP than a small rental property management office might need.

NETWORKING
It is a supportive system of sharing information and services among individuals and groups having a common interest.
A local-area network (LAN) is basically defined as two or more computers connected by a structured wire system for the purpose of sharing resources and files. In this chapter we will explain the various structured wire systems that the Network Engineer will deal with during the course of their job. Wireless LANs are becoming more and more popular, but even these devices rely on some amount of physical wires in most cases.
REQUIREMENTS
Network Adapter
A computer needs a network adapter to connect to a network. It converts computer data into electronic signals. It listens for silence on the network cable and applies the data to it when it has an opportunity. The network access element of its job is called Media Access Control, or MAC. The physical address of every computer on a network is called its MAC address. The MAC address is the network adapter's serial number. Most computers are shipped with the network adapter integrated into the motherboard. However, early PCs didn't include this function and computer owners had to buy it separately and fit it into an expansion slot on the motherboard. These were called "network cards" because they were sold on a separate card. Although network adapters are now integrated, the name network card is still used. The wireless equivalent is called a Wireless Network Interface Controller.
Network Medium
Wired networks need cable. The most common form of cable used in networks is called the "Unshielded Twisted Pair." In PC shops, it is generally just referred to as "network cable" or "Ethernet cable." Ethernet is the most widely implemented set of standards for the physical properties of networks. UTP is so closely identified with Ethernet that it is often given that name. Other cable types used for networks are twin-axial, Shielded Twisted Pair and single-mode and multi-mode fiber optic cable. Wireless networks don't need cable; they send data on radio waves generated by the WNIC.
Cable Connectors
In wired networks, the most common form of connector is the RJ45. Every computer with networking capabilities has an RJ45 port. This is sometimes called a "network port" or an "Ethernet port." The RJ45 plug looks like a slightly larger telephone plug and connects the Unshielded Twisted Pair or the Shielded Twisted Pair cable.
Power Supply
Both wired and wireless networks need a power supply. A wireless network uses the current to generate radio waves. A cabled network sends data interpreted as an electronic pulse.
Hub/Switch/Router
In wired networks, one computer cannot connect to many others without some form of splitter. A hub is little more than a splitter. It repeats any signals coming into one of its ports out onto all its other ports. A cable leads from each port to one computer. A switch ...LAN.pptx

Local area networks (LANs) connect devices within a small geographic area like a home or office. LANs use technologies like Ethernet cables or WiFi to share resources and data between connected devices. Common LAN types include Ethernet, wireless, fiber optic, and powerline networks. LANs allow devices to share printers, files, internet access, and collaborate in real-time, improving communication and productivity within the local network. Setting up a LAN involves determining requirements, selecting hardware, configuring network and security settings, and testing connectivity between devices on the local network.Exploration lan switching_chapter1

The document describes the key components of a hierarchical network design for a small to medium-sized business. It discusses the access, distribution and core layers, and how switches are selected for each layer based on port density, forwarding rates, bandwidth aggregation needs and other considerations such as power over ethernet and layer 3 functions. Topology diagrams are also important to understand traffic flows and potential bottlenecks.Strategic Corporate Social Responsibility: Sustainable Value Creation Fourth

NETWORKING
It is a supportive system of sharing information and services among individuals and groups having a common interest.
A local-area network (LAN) is basically defined as two or more computers connected by a structured wire system for the purpose of sharing resources and files. In this chapter we will explain the various structured wire systems that the Network Engineer will deal with during the course of their job. Wireless LANs are becoming more and more popular, but even these devices rely on some amount of physical wires in most cases.
REQUIREMENTS
Network Adapter
A computer needs a network adapter to connect to a network. It converts computer data into electronic signals. It listens for silence on the network cable and applies the data to it when it has an opportunity. The network access element of its job is called Media Access Control, or MAC. The physical address of every computer on a network is called its MAC address. The MAC address is the network adapter's serial number. Most computers are shipped with the network adapter integrated into the motherboard. However, early PCs didn't include this function and computer owners had to buy it separately and fit it into an expansion slot on the motherboard. These were called "network cards" because they were sold on a separate card. Although network adapters are now integrated, the name network card is still used. The wireless equivalent is called a Wireless Network Interface Controller.
Network Medium
Wired networks need cable. The most common form of cable used in networks is called the "Unshielded Twisted Pair." In PC shops, it is generally just referred to as "network cable" or "Ethernet cable." Ethernet is the most widely implemented set of standards for the physical properties of networks. UTP is so closely identified with Ethernet that it is often given that name. Other cable types used for networks are twin-axial, Shielded Twisted Pair and single-mode and multi-mode fiber optic cable. Wireless networks don't need cable; they send data on radio waves generated by the WNIC.
Cable Connectors
In wired networks, the most common form of connector is the RJ45. Every computer with networking capabilities has an RJ45 port. This is sometimes called a "network port" or an "Ethernet port." The RJ45 plug looks like a slightly larger telephone plug and connects the Unshielded Twisted Pair or the Shielded Twisted Pair cable.
Power Supply
Both wired and wireless networks need a power supply. A wireless network uses the current to generate radio waves. A cabled network sends data interpreted as an electronic pulse.
Hub/Switch/Router
In wired networks, one computer cannot connect to many others without some form of splitter. A hub is little more than a splitter. It repeats any signals coming into one of its ports out onto all its other ports. A cable leads from each port to one computer. A switch ...LAN.pptx

Local area networks (LANs) connect devices within a small geographic area like a home or office. LANs use technologies like Ethernet cables or WiFi to share resources and data between connected devices. Common LAN types include Ethernet, wireless, fiber optic, and powerline networks. LANs allow devices to share printers, files, internet access, and collaborate in real-time, improving communication and productivity within the local network. Setting up a LAN involves determining requirements, selecting hardware, configuring network and security settings, and testing connectivity between devices on the local network.Exploration lan switching_chapter1

The document describes the key components of a hierarchical network design for a small to medium-sized business. It discusses the access, distribution and core layers, and how switches are selected for each layer based on port density, forwarding rates, bandwidth aggregation needs and other considerations such as power over ethernet and layer 3 functions. Topology diagrams are also important to understand traffic flows and potential bottlenecks.Recently uploaded (20)

Antiviral agents are crucial in combating viral infections, causing a variety of diseases from mild to life-threatening. Developed through medicinal chemistry, these drugs target viral structures and processes while minimizing harm to host cells. Viruses are classified into DNA and RNA viruses, with each replicating through distinct mechanisms. Treatments for herpesviruses involve nucleoside analogs like acyclovir and valacyclovir, which inhibit the viral DNA polymerase. Influenza is managed with neuraminidase inhibitors like oseltamivir and zanamivir, which prevent the release of new viral particles. HIV is treated with a combination of antiretroviral drugs targeting various stages of the viral life cycle. Hepatitis B and C are treated with different strategies, with nucleoside analogs like lamivudine inhibiting viral replication and direct-acting antivirals targeting the viral RNA polymerase and other key proteins.
Antiviral agents are designed based on their mechanisms of action, with several categories including nucleoside and nucleotide analogs, protease inhibitors, neuraminidase inhibitors, reverse transcriptase inhibitors, and integrase inhibitors. The design of these agents often relies on understanding the structure-activity relationship (SAR), which involves modifying the chemical structure of compounds to enhance efficacy, selectivity, and bioavailability while reducing side effects. Despite their success, challenges such as drug resistance, viral mutation, and the need for long-term therapy remain.Analysis of Conf File Parameters in Odoo 17
