Figure 4. Result Packet Loss of Wired and Wireless (802.11g) by one user Figure 4 demonstrates the comparison for one user client between wired and wireless technology in terms of packet loss metric. As can see in figure 4, all file size is 0% means that files are successfully transferred for both technologies. However, in terms of duration there are a bit differences can be seen. For the first file size, 200MB, wireless takes one minute early to complete compared to wired technology but for 400MB file size, it is vice versa. The duration between both technologies is not much difference but for 1GB file size, there have a lots difference where almost to 6 minutes. This reason wired technology take less time rather than wireless because of wired have a consistent and stable connection if compared with wireless. Almost 100Mbps wired connection received but for wireless the bandwidth only at 54Mbps and the actual throughput is about half of data rate. Figure 5 shows the average of three users in terms of CPU usage. The difference is bigger for smaller file size such as 200MB file. The difference for both file size are 4%. While the CPU usage same during 400MB and 600MB file size test which is 39% and 40% and other file size is nearly same. As has been plotted o figure 5, the CPU usage of 400mb and 600mb are similar might because of the running programs on both technologies on the background is same. For 800MB, wireless CPU usage is higher than wired might because of that time wireless connection have heavy traffic where will affect to CPU usage. Since wired connection is constant and the traffic is constant too, CPU usage does not increase.

Too much programs run on the background will affect the CPU usage and the reason wired technology less CPU usage than wireless because of wired does not need any support device assistant. Example, on laptop it have wireless network card. This wireless network card needs a device support assistant where to reduce the CPU usage. If user does not install this application, CPU usage will be increase.

Figure 3. Average RAM Performance for Wired and Wireless 802.11g by one user Graph on figure 3 demonstrates the average of wired and wireless technology in term of RAM performance. Bigger difference can see for smaller file size, 200MB which is approximately 5%. By 400MB file size, the differences for both technologies is 2% however on 600MB and 800MB the RAM performance is similar for both technologies and for 1GB file size, wireless technology decrease to 44% meanwhile wired increase to 45%. Theoretically, RAM performance is related to CPU usage. When CPU usage increases, RAM performance will increase too. The reason why RAM performance of wireless technology is higher than wired because wireless using more power usage which needs to process more applications rather than wired connection.

Figure 6. Result RAM Performance of Wired and Wireless (802.11g) by three users Figure in 6 shows the RAM performance for both technologies; wired and wireless by one user. As has been plot in figure 6, performance of RAM on wired connection is lower compared to wireless. The difference between both technologies roughly is 6%. The reason why wired connection use minor performance rather than wireless because wired connection does not need any extra power usage. Besides, wireless interference on wireless connection also as a reason why wireless RAM performance increase. When wireless technology has much interference from outside, it needs more process to complete the file transfer.

Figure 7. Result Packet Loss of Wired and Wireless (802.11g) by three users Result from figure 7 above shows there is a difference between wired and wireless packet loss. For wired, only 95% file has been received and another 5% is loss on 600mb for other files size is successfully transferred. As can see in figure 7, wireless on 600mb and 800mb file size, there is a packet loss where each of them is 14% and 13% and others is successfully transferred. Wireless has two times packet loss might because of the stability of the connection itself. Wireless is using wave as a transmission medium while wired is using cable to send a data. Much interference from other access point which operate at same frequency, 2.4 GHz since testing have been done on Level 4, UniKL City Campus while for wired connection, and no interference happen since wired connection is stable. ampus while for wired connection, and no interference happen since wired connection is stable.

Figure 10. Result Packet Loss of Wired and Wireless (802.11n) by one user Figure 10 reveals that there is no packet loss for one user client between wired and wireless technology which means files are successfully transferred. However, in terms of duration as reveals on figure 10, there are a bit differences can be seen. For 200MB file size, wireless takes one minute early to complete compared to wired technology but for 400MB file size, it is vice versa. The duration between both technologies is not much difference however for 1GB file size; there have a lots difference between both technologies where nearly to 5 minutes. This is because, the network speed of wireless technology itself are not consistent compared to wired where the data rate is 100Mbps. Even speed for IEEE 802.11n is 108Mbps, but actual throughputs is about half of data rate. This is the reason why wireless takes more time to complete file transferred.

Figure 11. Result CPU Usage of Wired and Wireless (802.11n) by three users Figure 11 shows the differences CPU usage between both technologies; wired and wireless 802.11n approximately is 12%. The bigger difference is on 800mb file size which is 22% and on 1GB file size, CPU usage of wireless decrease until 34% as plotted on figure 11. Here performance of CPU usage was collect from three users with different hardware specification. Hardware specification gives a big impact on the CPU usage where lower processer will get higher CPU usage. Also, on wireless it has laws of radio dynamic where using more power to connect to access point and this will effect to CPU usage compared to wired where directly connected to switch.

Figure 12. Result RAM Performance of Wired and Wireless (802.1 1n) by three users Figure in 12 reveals that the RAM performance for both technologies; wired and wireless it still increase when the number of users increases by three client. As has been plot in figure 12, RAM performance for wireless technology increase on up 69% and 73% on both 600MB and 800MB files size. However, for wired connection RAM performance is much more consistence from 200MB until 1GB where the percentages start from 52% until 54%. Different specification on hardware requirement on each client will affect RAM performance in addition on wireless technology itself have an extra usage where can increase the performance of RAM. Therefore, this is the reason why wireless RAM performance is higher than wired. Graph in figure 13 demonstrates the packet loss and duration of wired and wireless technology to complete file transfer. Both technologies on 600mb have a packet loss which each of them received only at 95% and 83%. Besides, on 1GB file size, wireless have another packet loss which only received at 84%. Other file size is successfully transferred. Packet loss happen on wireless might because of network congestion on the wireless traffic. On wired, packet loss happen because of the faulty of the device itself where one of the client computer automatically shut down. High packet loss will reduce the performance of network. In terms of duration, wired technology takes more time to complete the files transferred when compared to wireless 802.1 1n. This is because, the new technology of wireless are using Multiple In, Multiple Output (MIMO) where used several antennas to move multiple data streams from one location to another location.
