User Datagram Protocol

The three main different privileges are read, write and execution. If they have reading privileges then they are allowed to access the file in a read only format. Write privileges lets the user to edit and replace the existing files. Execute privileges are only relevant when trying to run programs. The benefit of using this kind of system is that it makes certain files and documents more secure. As it assures only people with the right credentials…

browser is a program which allows me to browse web pages such as my sync email account. You need a domain name to identify the IP address to have access; they are used in URLs to find particular web pages. URL first part is named a protocol finder and indicates what protocol should be used, the last part is a resource name and it identifies the IP address of where the resource is placed. The web hosting services allows you to store information on the web pages that I have typed to search for.…

other. To achieve this, multiple access protocols coordinate the transmission. The three classes of multiple access protocols are, random access, taking-turns and channel partitioning. With random access protocol, each node tries to randomly to use the complete broadcast link, without any regard to the other nodes. Taking-turns protocol uses some type of turning mechanism, which designates which node is allowed to transmit. Channel partitioning protocol divides the channel (time slots,…

It was a cold winter day. We were running out of wood in the basement and I was always the one who helped my dad put more into the basement. I was in the third grade and loved helping my dad outside with his chores that he had to do. My dad told me that he was going out to put some wood in the basement and I began bundling up in my warm winter clothes. I put on my snow pants, coat, boots, hat, and work gloves before heading outside to help. My dad was pulling out of the garage on the four…

This past December, Toronto broke its thirty-six-year-old record for the warmest Christmas Eve to date. Climate change can be characterized by long term changes in weather conditions, including shifts in temperature, precipitation and extreme weather events. Human induced climate change was discovered after the industrial revolution. This is when scientists noticed the warming of the atmosphere, through the greenhouse effect. Clear evidence of the costs of climate change can be found in…

Bilal Bourouf 260500473 Assignment 2 Geog200 My essay on Kyoto protocol Introduction: Greenhouse gases are primarily made of water vapor and other elements such as carbon dioxide, methane and nitrous oxide [1]. This gas is emitted mostly by energy plants, transportation vehicles and deforestation. In a huge amount, it acts like a thermal blanket for the Earth conserving the heat which leads to important environmental problems such as global warming [2]. These gases are generated by all…

Internet protocol version four (IPv4) is the current networking protocol used by any device that is connected to the network today. Internet protocol defines a set of rules on how data packets are formatted and sent across the Internet or local network (Carroll, 2014). The issue with IPv4 is that its available Internet address space is running out (Banks, 2015). Today, more and more electronic devices will need Internet addresses in order to communicate with other devices. Devices such as…

My first day at Penn Machine, I learned quite a lot. I had learned that I will be going to the Johnstown location as well as the Blairsville location. My first day I went to the Johnstown location. I went around all the offices and down around the factory and met all the employees. After that my supervisor showed me how all the IP addresses work with all the devices in the company, then he showed me logon scripts. This was really all new to me. I am more of a visual person, so in school we…

Packet switching. What they called ARPANET led to the development of the internetworking, where multiple networks could be join together over to create a network of networks. IP defined by RFC791 was the first widely used version of the internet protocol. This was known as version four, this would make you think that there were three other version of IP before this version however there really was not. IPv4 was originally designed for an internetwork, a fraction of what the size of the internet…

The Kyoto Protocol was designed to fight the global warming by reducing greenhouse gas emissions. Global warming is defined as the increase of the earth’s average surface temperatures due to the greenhouse effect, which acts to trap heat that would have otherwise escaped from earth. The Kyoto Protocol is able to reduce global warming by forcing countries to reduce greenhouse gas emissions, therefore reducing the greenhouse effect. The initial goal of the Kyoto Protocol was to reduce worldwide…
