(M3) compare and evaluate the effectiveness of the transfer of data over both wireless and wired networks

Discuss the advantages and disadvantages of data transfer across wired and wireless networks while considering the effectiveness and accuracy of both media.

1. Data that your computer intends to share over a network is first sent to the network's wireless adapter. This information can be anything from sending and receiving large files to simple text instant messages from one computer to another. The adapter translates this information into a radio signal, which it then sends over an antenna either directly to another computer or to a router. 2. The other computer (via another wireless adapter) or the router receives the radio signal and converts it back into a format that computers can understand. Once this has happened, the information can be accessed by all computers on the network, if made accessible to all. This entire process can happen quickly for small files, or can take some time depending on file size and speed of antennas and routers. Clearly, this process is limited by distance, strength of signal and size of files so the accuracy of data may not be as high as that transmitted using cables. While large data transfer is usually accurate across a cable network it is when messages are sent across different networks or via modem conversion that errors in data can occur. For example you could create then expand on each point using a simple table such as the one shown below: WIRED

Advantages Disadvantages Accurate large file transfer Problems associated when crossing different Fast transfer rates network structures Very effective for medium and large sized May be a problem when too many machines companies where high levels of network access is need connectivity at the same time required

Non WIRED

Advantages Disadvantages Mobile access Data may be inaccurate if signal is poor Cheap and easy to set up for small networks Can be difficult to set up shared printer access Ideal for small home or limited retail networks Can be easy to infiltrate Often used in office environment to allow for convenience of access

CONCLUSION You will also need to add a conclusion to the topic which informs and summarises about the differences, strengths and weaknesses of each system as they apply to both business and home use.
