FTP is used when transferring files over the internet to another network. A switch as a networking device is times better than a hub.

Unit 44 Local Area Networking Technologies Assignment solution

In theory this is how OSI would work as well. We can find Ethernet in every network and data is flowed with speed.

Assignment 1

The sending node sets a specified amount of data it can send and the receiving node changes that number depending on the network traffic. This protocol is better for things like music or video streaming.

Devices used in this layer are known as building distribution switches and should have the following capabilities: It uses MAC address as source address. The resulting network is efficient, intelligent, and accessible and easily to managed. It can be because of delay in data processing or delay in establishing communication with destination or due to delay in processing at source end itself.

It also requires changes to the access, security and ownership of the data which passes across the LAN. Ip is used to tell the packets where to go and the best route to take to get to the address of the recipient.

Often forgot about is a Physical networking unit 10 assignments ring network card. If packets are dropped it will not check if any packets are dropped and it wont ask for them to be resent making the protocol faster than TCP.

For more details and other essential parts click on this link http: The third message is the node sending the packets to the other node. FTP is like HTTP however it allows the user to access files from a server and allows the user to download that particular file.

There is also de-multiplexing which takes that one single signal and puts it back into the multiple streams of data. It can be varied from one packet to another.

Session — This layer creates, maintains and terminates the connection between the receiver and sender. Within the switched internet work, VLANs provide segmentation.

They set the standard for the information transmitted. A switch is a layer two network device. Presentation — Used to translate the data to be displayed in the application layer, it formats the data to fit the application.

It can control connections between multiple nodes. The network topology, cables and type of network device such as a switch or hub are all parts of the physical layer.

This is a very costly method as many lines would need to be open for something like the internet making upkeep very expensive. CRC Cyclic redundancy check is very accurate way of error detection, it detects errors in data transmissions.

Switch - Router - Router - Switch. They are all put back together when at the destination. The purpose of QoS is to manage either one or all these four characteristics.

It is used by the network applications to define the protocols to use for the network. Network access — Is used to move Bits over the network, much like the physical layer in the OSI model.

So only the frames that have errors in them are requested again. Circuit switching — Is much like a telephone where the devices occupy one channel and only those devices can access that channel. Each layer is exacted in order however Physical networking unit 10 assignments order is different for sending and receiving as sending would start at the application layer and receiving would start at the physical.

A dedicated line would be needed to keep communication up. SMTP is used in the transfer of mail and attachments linked to that mail over the internet. Which avoid data from collision. It checks for changes in Raw computer data after a transmission of data from one place to another happens.

A router connects to other routers to determine the source of the packets sent from the destination or it checks the router for any knowledge of your destination. It detects accidental changes to data often used in communication networks and in storages devices like hard drives.

Data Link — Its main job is to check for errors when receiving packets from the physical layer, this is one of the jobs it has and is often called Logical link control LLC layer. The router is used to find another router, which uses the mac address sent from the other machine to find the switch and vice versa.View Notes - Unit 8 - Assignment from NT at ITT Tech Pittsburgh.
