Internal This section of the analysis will be based on observations from Amy Dowson’s year three class at Kingsley Primary school, Armadale. 3.0 Environment The classroom environment is one that promotes acceptance, communicate and allows for various styles of learning. Upon entering the room, it is noticed that there are several different learning areas of the room. The desks are in rows, allowing for independent work, there is a reading corner with bean bags, there is a guided reading corner, as well as having space around the room for small group learning activities. Another important aspect of the environment is the mat at the front of the room for explicit teaching times, so that the whole class can sit and focus. This environment allows for easy accessibility to all areas of the room as well as encourages ownership of learning. This environment caters for variation of instruction and has whole class, small group and individual work places. Having the teacher’s desk in the corner of the room facing outwards allows for ‘withitness’ during class activities. Withitness is the ability to know what is happening in the classroom at all times, be able to divide their attention amongst tasks and provide preventative behaviour management before an issue occurs. Frequently, Miss Dowson changes the layout of the room and where the children are placed. The students are moved around so that they form relationships with the entire class, as well as create a rapport that produces a…

Foundation of Personal Communication Defensive Climate is a situation where one perceives or anticipates some form of threat and feels like they need to defend themselves from the unknown and become cautious with their surrounding and people around them. For example, your supervisor makes statements that imply that you are always late, and you know you have only been late once: you tend to be defensive. On the other hand, Supportive Climate is a state of a stress-free and healthy environment,…

avoidance if the sender receives triple duplicate ACKs, then it performs fast-retransmission and enters into fast-recovery. In fast-retransmit the sender retransmits the lost segment,sets the threshold value for slow-start as ssthresh = cwnd/2, and sets congestion window, cwnd = ssthresh+3 segments. In fast-recovery, the sender increases its congestion window by one segment for each subsequent duplicate ACK received that indicates a segment is reaching the destination. It can transmit new…

If the server sends a file to the receiver, and it receives it near the end of the packet lifetime, then the ACK may take longer to receive then what is left on the packet lifetime, so the server may send another packet before it receives the ACK leading to duplicate packets. 4.Give one potential disadvantage when Nagle's algorithm is used on a badly congested network. A big problem can occur when Nagle's algorithm is used alongside Delayed ACK, another method used to help prevent…

a local host or client and a server. Basically requires three steps from both the client and the server to exchange SYN and ACK packets before any communications begins. First the client sends a SYN packet asking the server if is open for a new connection, then the server responds with a confirmation packet or SYN/ACK, to what the client responds with an ACK packet and the connection is established. 3 way hand shake is better because the server gets the confirmation from the client that a…

In 1985 war in South Sudan caused many people to starve, dehydrate, or get sick from the water. Salva Dut faced most of these throughout his life. In the book A Long Walk to Water Linda Sue Park wrote about Salva’s journey away from the war, and everything that happened during his trip to safety. It talked about everything from him leaving school because the war to him moving to New York. Salva went through so much throughout his life one major issue being war. “CRACK! POP-POP-CRACK!…

I say this because when Salva was in school, he heard the shooting and he ran into the bushes, to get away from the shooting and didn’t look back. I can support this because in the book it states “He continued the lesson from where he left off then- CRACK! POP-POP-CRACK! ACK-ACK-ACK-ACK-ACK-ACK! Gunfire!” This quote shows how Salva's life changed just like that but also it shows that he was confident to run into the bushes when there was a fire and everyone was running. Another reason why Salva…

Pop! Crack pop! Ack-ack-ack-ack-ack! The gunfire sends Salva's teacher into a frenzy in which he commands them to run into the bush. Little does Salva know, this action will change his life forever. Sound cliché? Salva’s whole story follows his struggles to survive and his will to find his family, so this is not an overstatement. The aforementioned example is just one of many stories and scenarios in which a character or in fact a real person is compelled to set off on a life changing journey.…

Sequence Number (32bits) – Each segment is assigned a sequence number, which specifies the number assigned to first byte of data in current message. Next, if data not received, acknowledgement is not sent. Acknowledgment Number (32bits) – Contains value of next sequence number that the sender of the segment is expecting to receive. Once a connection is established this is always sent DataOffset (variable length) – indicated number of 32bit words contained in TCP header Flags (6bits) – 1 or 0…
