The elements of a TCP three-way handshake process

 

 

The elements of a TCP three-way handshake process are as follows: The first step is the Synchronize Sequence number or SYN by the client. This sends data packets from the client to the destination server to ensure a port is open to establish a connection.

The second step is the Acknowledgement Sequence Number (ACK) or SYN/ACK packet. This has two actions. The first action is the server acknowledging the SYN packet sent by the client. This is done by sending an ACK packet to the client. The second action is the server sending its own acknowledgement data packet or SYN to the client. I believe both packets are sent at the same time which is why this step is called SYN/ACK.

The third step is the client sending an ACK to the SYN/ACK packets from the server. This completes the three-way handshake, the client and server connection is created, and the communications can begin. If a connection fails, a finish or FIN will be sent by the client and server indicating that the connection has been terminated. Both will also need to send an ACT to complete the process.

Question B

Centralized routing is a technique for providing routing information that dictates that the routing information generated from the least-cost algorithm is stored at a central location within the network (White, 2016, p. 403). This would be easy to manage because all the routing information is stored in one location but it is also the single point of failure. Distributed routing is a wide area network routing technique in which each node maintains its own routing table (White, 2016, p. 404). Access to the routing information is available in different locations throughout the network. This makes it easier to access routing information and provides redundancy.

In my opinion, a distributed network routing method would be more efficient for an organization with a high volume website due to the availability of the routing information throughout the network. A centralized routing may get overwhelmed in high volume websites.

Sample Solution

Accordingly, could this multitude of elements at any point impact the learning of understudies? Contrasting the two schools’ exhibitions there appears with be almost no distinction. Truth be told, arrangement 2 (where very little innovation is utilized) have improved brings about the advancement 8 scores and thusly an expanded number of understudies accomplishing A*-C in the GCSE brings about the mid year of 2016. Consequently, this enquire can’t uphold completely the possibility that learning innovations upgrades learning.

Be that as it may, the advantage of learning advancements utilized in study halls is apparent. With the utilization of games, for example, Kahoot, the advantages are endless: when the game is played, 100 percent of understudies are focusing on what’s going on toward the front, contrasting and other learning exercises; it can build the degree of fixation; it is tomfoolery and propelling; it can prompt the understudies to like that specific instructor, or that specific subject, on the grounds that is fun; Learning advancements are viewed as expanding understudies’ certainty and inspiration by making school work more agreeable. Understudy’s perspectives and contribution in learning change and it is considered as tomfoolery and not as standard training.

However, what makes a useful study hall climate, where it are utilized to learn innovations? Koehler et al (2004) propose that innovation, similar to language, is a mechanism for articulation, correspondence and request that can assist educators with tackling educational issues in study halls. In this manner, educators’ capacity to utilize innovation should be firmly associated with their capacity to educate; that is, great educators with innovation should be first great educators. Adding to that, BECTA (2008) contended that learning innovations can make an imaginative climate in the study hall, through the outflow of thoughts, to utilize a blend of instinct, rationale, reason and immediacy and to make associations between homeroom work and outside encounters.
