Understand physical and logical network topologies
1.1 Describe common physical network topologies There are 7 most common topologies that most people will use. The first one is a ring topology this works with 2 or more of the host in a circle by passing a token around the token never stops moving it will grad the data that need to be attached and take it to that giving computer mac addressee.
The second one is a Mesh topology. This topology works by ensuring that every host is connected to more than one of the other hosts computers. The main purpose of these topologies is to do fault finding. As long as 2 computers are working and connected the LAN will still work.
The third on is. A star topology this topology works by having a signal

Computers allow the client/user to interact with different systems
Switches this will send data to multiple computers at the same time.
Software
Protocols this are set in place so that you can connect devices to the network.
Firewall this helps to stop any unwanted attacks on you server/computer.
1.4 Identify the bandwidth limitations of different types of network cabling and connectors
With copper cable you have a very limited speed that you will get this can be from 1mb up to 30mb but the speed will also dissipate over the length of the copper cable as well so this will put limitations on the speeds.
With fibre cable you will get a constant speed over any distance as the data is transfer via light it will never dissipate and you can get speeds of up to 200mb and is soon to get faster.
1.5 Describe the different types of wireless standards
Personal Area Network (PAN)
A Personal Area Network (PAN) is used by mostly only one person this will allow them to make a connecting to the internet. This comes in the form of setting up a hotspot on your phone and connecting your laptop to it. This comes in handy if you don’t have internet around you but you phone is still picking up
Connection speeds for DSL typically range from 1.544 Mbps to 512 Kbps downstream and around 128 Kbps upstream. In addition, a DSL line allows for one line to carry both voice and data signals, and for the data part of the line to be continuously connected. DSL achieves higher data transfer rates by utilizing more of the available bandwidth spectrum. Ordinary telephone service only makes use of the 0 – 3400 Hz frequency range, which accounts for the 56 Kbps speed limit on standard analog modems. DSL eludes the 3400 Hz frequency boundary by outmoding the digital-to-analog conversion that modems perform and
Several components required to implement VPN depends on the type of VPN i-e. Remote Access VPN, or site-to-site VPN. Network design is crucial to decide the throughput, choice of devices and number of users. There are two types of networks where VPN is needed to implement. 1. Site-to-site VPN—is provides connection between branches i-e. LAN-to-LAN VPN with their own internet instead of dedicated leased lines.
Understanding networking is a fundamental part of configuring complex environments on the internet. This has implications when trying to communicate between servers efficiently, developing secure network policies, and keeping your nodes organized. Every location or device on a network must be addressable. This is simply a term that means that it can be reached by referencing its designation under a predefined system of addresses. In the normal TCP/IP model of network layering, this is handled on a few different layers, but usually, when we refer to an address on a network, we are talking about an IP address.
Sharing Internet Access: within a computer network learners are able to access the internet at once. Speed: Using a network is a faster way for sharing and transferring files. Without a network, files are shared by replicating them to a floppy disk. Cost: Networkable versions of many popular software programmes are available at significant savings compared to buying individual licensed copies. It also allows easier upgrading of the program.
This software enables you to watch what happens on your cell phone on a bigger, computer screen and
5. Public trials and executions serve as a deterance of deviant behaviors. These sanctions act as a way to set an example and for people to see what will happen to them if they do the same thing, These sanctions can also be seen as reinforcing boundaries. Although public executions and trials in “town square” are not as common in most countries today, the media is utilized to fulfil the same purpose. When there are high profile cases going on in the United States often tmes the full trial and sentancings are televised so that much of society can see what the repercussions are for defying a social norm.
When asked what a network is, I usually think about the internet or my phone’s network. It had never occurred to me to go further in depth on the subject. In order to fully understand what a network is we must look into what all networks have in common. All networks whether they are a broadcast, a computer, or a business network (the list goes on) all share common traits. There exists a hierarchy within each network and the more connections one has, the better.
Cell phone towers allow your phone to easily connect to the internet and access information, get directions through your GPS, and communicate with Face Time with friends and family. Wireless internet in Pompano Beach makes life a lot easier as well. Even though you can try to directly access the wireless network at home through the use of cell phone towers, the best way to go involves purchasing a mobile or Wi-Fi hotspot. This tool helps strengthen the connectivity and allows you to get a better internet connection for all of
These hotspots help to strengthen the wireless connection so that it can route through to all the devices that
Adaptive Location Data Buffering provides two different methods to occasionally confirm an open end-to-end connection with the server. If the IP address of the device is publically addressable, the server can occasionally send “alive” messages via single UDP packets to the phone. If, for security or capacity reasons, the cellular provider does not allow publically addressable IPs, the Adaptive Location Data Buffering module occasionally opens a TCP connection from the phone to the server to determine if there is a successful “alive” response from the server.
Throughout this course we have learned about many aspects of Information Systems, how they work, and how an organization relies on their Information Systems. We have come to understand that there are key components to every information system. These components are first and foremost the users or people, they are the ones who will be utilizing the systems, second is the hardware, this is all the equipment needed for the system, it would be things such as the computer, a monitor, a mouse &/or a keyboard. Software is the programs, the tools within the system that are specific to the users needs, data is another component, this is all the information that goes into the information system, data goes in so the user can extract what it needs, networks,

The Dangers of Aluminum Wiring in Residential Homes Your electrical wiring is an important aspect of your home. And it goes without saying that having a reliable electrical wiring system that lights up and powers up your home safely should be one of your top priorities. When it comes to the materials that are used for wiring, available are plenty of options, including aluminum, copper, silver and more, with each material having its own set of advantages and disadvantages. Over the past few decades, aluminum has been a popular choice for Calgary homeowners due to its relatively affordable cost but not anymore.
