wireless network is an amazing wireless technology which has totally changes the means of communication.
. There is no business, industry, project which can be progressed without the needs of wireless networks
A wireless local-area network (LAN) uses radio waves to connect devices such as laptops to the Internet and to your business network and its applications. When you connect a laptop to a WiFi hotspot at a cafe, hotel, airport lounge, or other public place, you're connecting to that business's wireless network.
in the past, some believed wired networks were faster and more secure than wireless networks. But continual enhancements to wireless networking standards and technologies have eroded those speed and security differences

Physical media


With physical media we mean channels where the person who is talking can be seen and heard by the audience. 
The whole point here is to be able to not only hear the messages but also to see the body language and feel the climate in the room. 
This does not need to be two-way channels. In certain situations the receiver expect physical communication. This is the case especially when dealing with high concern messages, e.g. organizational change or down sizing. If a message is perceived as important to the receiver they expect to hear it live from their manager

Wireless network 


Wireless network a magic word which can change your status very promptly that can get access to internet very speedily, and make possible conversation more and more than two users such as text messages, downloading and uploading of pictures, hear online radio, music and video downloading with a very high speed. Wireless network offering hotspot therefore now the usage of internet at airport, business companies is not an issue now.

Nice keep it up

Wireless media take in radio frequencies, microwave, satellite, and infrared. The wireless network will cover a vast range of communication in future. Usage of wireless media is faster. It is also less costly than the cable network. Wireless is also useful where environmental circumstances make it impossible or costly to use cable. There are few disadvantages with wireless. The data rate of wireless media is much less then guided media. Although with new developments in wireless broadband this issue is becoming less. Wireless is also greatly affected by external impairments, such as the impact of unpleasant weather. Due to the unpleasant weather reliability of wireless network can be difficult to guarantee. However, new developments in laser-based communications, such as virtual fiber can improve this situation. On the other hand the data rate of the Physical media much more then wireless media it also provides a much more secure communication path sender and destination. But cabling in the physical network is more expensive. Networks that are based on physical media provide physical access is to the building and to the network cabling. Unauthorized security in the physical network is more reliable then the Wireless communication. Wireless communication can be intercepted by unauthorized personnel attempting to attack privacy. It is also much easier for a wireless user to attempt unauthorized networks access. In my opinion physical media can never remove in the future. Due to the above problems with the wireless media. Uses of physical media become less then the wireless media but it can never totally remove in the future.

thx

Physical means copper wire or fiber that connect computers togathere Wireless networking ,as an alternative can be more convenient that physical media but will naver able to perform as well as cable.Copper and fibre are important to high performance data links and long distance backbone networks.Specific standards specifies wireless connection rates of about 100 megabits per seconds,possibly up to 200 megabits per seconds depending on wireless condition.Wire based networks at speeds of 100 Megabits per seconds The IEEE 802.3u appeared in 1995 followed by 100 megabits per seconds networks .Physical media allows multiple computers to connect to a switch over a dedicated communication path.While wireless networks have a nominal range of 100 to 200 meters Connections over fiber optic cable at a 1 gigabit per second can be 5 km about 3 miles ,or greater .Physical media is much more secure communication path .Wireless communication path can be intercepted by unauthorized personnel attemping to invalid privacy.Physical communication Media wire ,cable and another touchable materials used to send communications signals,They are called physical communication media. Wireless network is amazing wireless technology which has totally changes means of communication. Wireless network a magic word which can change your status very promptly that can get access to internet very speedily,and makes possible conversion more and more than two users such as text message ,downloading and uploading of picture.hear online radio,music downloading with a very high speed such type network offering hotspots therefore now the uasage of internet at airport,business companies is not an issue now.In the past ,some believed wired networks were faster and more secure than wireless networks.But continual enhancements to wireless networking standards and technologies have eroded those speed and security differences.Physical media is much more realiable than the other wireless communication.Wireless communication can be subjected to interference from outside sources.Wireless networks can be intentionally jamped or subject to unintentional interference.Networks based on physical media are subject to much less interference and are nearly impossible to intentionally jam availability

   As we all know wireless network is the most important part of any business ,industry or project now- a-days .This technology makes our lives more comfortable and effective in the form of mobiles,laptops and radio.Now wireless network also offering hotspot therefore the usage of internet at airports and business companies is not an issue,But besides all this , its not possible to use this facility without physical communication media in my opinion Submarine internet cable is the example of this which is the basic and most fundamental part of internet in the form of physical communication media.

So I am not saying it is impossible to completely change the physical media into wireless media. It could be possible in the future but according to today’s conditions the best choice is the combinations of both wireless and physical media. Both physical and wireless media has some do’s and don’ts. Physical media has some qualities like less cost, cover longer distance, better security and good reliability. Wireless media has its own qualities like convenient, no wires problem easy mobility.

But these two have different disadvantages.Wireless media is slower, less secure, more complex to configure and also affected by surrounding like walls basements. Physical media also has some flaws like no mobility, cover more space and wired should be connected to power. So at the end I will say it could not possible to completely remove the physical media it is using on a large scale it has many advantages. We have to use both physical media and wireless media for best results.   

Networks based on physical media have 1,000 to 10,000 times as much performance as wireless networks. Physical media is critical for high-performance networks.Wire-based networks at speeds of 100 Megabits per second, the IEEE 802.3u, appeared in 1995, followed by 1000 Megabit per second networks, 802.3ab, in 1999. Wire networks running at 10 gigabits per second appeared in 2002 and documents released in 2010 show the road map from 100 gigabit per second networks to Terabit networks.

Wireless networks have a nominal range of 100 to 200 meters (about 300 to 600 feet). Connections over fiber optic cable at 1 gigabit per second can be 5 kilometers, about 3 miles, or greater.Physical media provides a much more secure communication path. Wireless communication can be intercepted by unauthorized personnel attempting to invade privacy. It is also much easier for a wireless user to attempt unauthorized networks access. Networks based on physical media mean physical access is required to the building and to the network cabling.Wireless networks can be intentionally jammed or subject to unintentional interference. Networks based on physical media are subject to much less interference and are nearly impossible to intentionally jam availability.

There is a fact the wireless media increasing its value in the eye of the people in advance century. Now in these days we see most of the people prefer the wireless media. It gives reliability to the users. According to my opinion in the near age we will not see the physical media. Because there is the big problem of the wire expense it’s the meager problem that reduce the value of the wired media against the wireless media have not any rubbish of wire and having not tension of wire expense. In Pakistan and most of the developing country there is the problem of the electricity and wire media definitely depends upon the electricity as compare the wireless media not much depend on the electricity we can also use the wireless media in the absence of the electricity. So according to me wireless medium is most sufficient in these days and also in near age and so on.

Idea 01:

It's very simple actually. You always use it, you just don't realize it.

In an indefinite integral there are no limits, so you basically just write down the anti-derivative.
In a definite integral you get have limits so you take the anti-derivative with each limit and subtract them, and then what happens is the constant of integration gets subtracted from itself which results in zero, hence it would seem that there is no constant of integration.

Idea 02:

All the anti-derivatives in the function of the integral are only defined up to an additive constant. This generally solves the possibility for a variable in an equation. Integration means reversing differences. This isn't used in definite because they have variables so you can solve the equation, you don't need to find possibilities that add up to the constant.
