Optic fibers are acclimated broadly in the medical acreage for diagnosing and alleviative a array of ailments. Because optic fibers can be fabricated acutely attenuate and fabricated into adjustable strands, they can be acclimated for admittance into claret vessels, lungs and added genitalia of the body. Optic fibers accept been enabling physicians to attending and assignment central the anatomy through tiny incisions with an apparatus alleged an Endoscope. An Endoscope is a medical apparatus fabricated to backpack two bundles of optic fibers central one continued tube. One array of optic cilia directs ablaze at the tissue actuality examined, while the added array of optic cilia transmits ablaze reflected from the tissue, bearing a abundant image. Endoscopes may be advised to attending into specific areas of the animal body. For example, physicians can use the optic fibers in the Endoscope to appraise knees, amateur and added joints in the body.

Arthroscopy (pronounced ahr-THROS-kuh-pee) is a address of application addition medical apparatus alleged the Arthroscope. This apparatus is beeline and cylinder-like with a alternation of lenses and optic cilia bundles that appear in sizes of 1/12 to 1/5 inch (2 to 5 millimeters.) The Arthroscope is acclimated to appraise a collective in a body, such as knee joints, ankles, elbows, achievement and shoulders. This is done by the Arthroscope actuality amid into a collective of the anatomy through a baby incision. A ablaze is again transmitted by the use of the optic fibers to the tip of the Arthroscope to brighten the joint.

1.    Network interface(Data link) layer
2.    Network layer
3.    Transport layer
4.    Application layer

Network interface layer
The lowest layer of the TCP/IP model. Its task is to provide access to the transmission physical medium and it differs according to the implementation of the medium.

Network layer
The network layer provides network addressing, routing and datagram transmission.  Used protocols that will be of interest further regarding DHCP are IP and ARP.

IP protocol
It is the basic protocol of the network layer and in general the internet as a whole. It sends datagrams, which are independent units that contain information about the destination, source and the sequence number of the datagram. The sequence number is used for message reconstruction, since the delivery order of the datagrams might not be the same as their order in the message and delivery reliability isn’t guaranteed at all.
IP protocol versions:
“    IP v4 - 32 bit addresses. Provides approximately 4 billion unique addresses which aren’t sufficient at present times.
“    IP v6 - 128 bit addresses. The transition to v6 will bring (is bringing) higher security, QoS, packet segmentation and many more IP addresses. (the transition from IP v4 to IP v6 must be supported by the system provider)

ARP protocol
The ARP abbreviation stands for Address Resolution Protocol. This protocol is used to find the physical address (MAC) based on a known IP address. If required ARP sends information concerning the wanted address to all the stations in the network - Broadcast. The stations consequently answer with a message containing their MAC. If the wanted device/station is outside the node/segment, the appropriate router will answer instead of it.

Transport layer
The transport layer is implemented only in terminal devices and it adjusts the behavior of the network according to the requirements of the device/application.

Application layer
The application layer is composed of programs that use net services to fulfill the needs of users. Examples of specific protocols are for instance FTP, DNS and DHCP.
Application protocols use TCP, UDP or both services at the same time. So called ports are used to differentiate between application protocols, they represent a type of label of the application. It is possible to change the ports in the settings of the service, but each service has a default port that isn’t changed for most services and is used as an unwritten standard.

“    FTP = 21
“    DNS = 53
“    DHCP = 67 + 68

If you already have a wireless network for your computers, you may be very interested in what’s coming next. Would you like it if your PDA, your mobile phone, your mp3 player and almost everything else you connect to your computer could be wireless too? It’s already a reality…

Personal Area Network.

Using wireless networking with your personal gadgets is often called PAN, which stands for Personal Area Network. The idea is that, in the future, we’ll all have laptop computers with their batteries charged and no more need to connect any wires to them at all — you just place your Bluetooth device near the computer, and the computer sees it and can use it straightaway.

Bluetooth has been around and in-use since 1999, and it’s only getting more popular. It was designed to be secure, low cost, and easy to use from day one.

There are two classes of Bluetooth that are in popular use: class 1 and class 2. Class 2 is the most common and cheaper standard, allowing you to use a device that is up to 10 metres (32 feet) away. Class 1 is rarer, but you can still find devices that use it easily enough, and it has ten times the range: 100 metres or 320 feet.

How Does It Work?

Bluetooth is more flexible than 802.11 wireless networking, in exchange for the shorter range. Essentially, a Bluetooth-enabled computer has one Bluetooth receiver installed in it, and this receiver can then be used with up to 7 nearby Bluetooth devices. On the other end, wireless devices do not need to have Bluetooth installed if they support it — it is already integrated.

Like 802.11, Bluetooth works by using radio signals to create bandwidth. It is not, though, the same thing as an old-style wireless mouse or keyboard, which required a receiver to be plugged into one of your computers’ ports, and didn’t have range or stability anywhere near that of Bluetooth.

Many computers now come with built in Bluetooth, especially Apple Macs. If you want to add Bluetooth to a computer that doesn’t come with it pre-installed, you should probably use a USB to Bluetooth adapter, although internal Bluetooth devices to install in your computer are available. If you have a laptop and a spare PCMCIA slot, you can get Bluetooth cards for that too.

What Can You Do With Bluetooth?

Mobile phones with Bluetooth are very popular, and so are PDAs — the instant synchronisation of addresses and calendars to a computer is a useful feature. Other than that, almost anything that would usually use USB can be done using Bluetooth, including digital cameras, mp3 players, printers, and even mice and keyboards. If you take a look through the comprehensive list of Bluetooth ‘profiles’ (kinds of devices that could, in theory, be Bluetooth enabled), it includes cordless phones, faxes, headsets, and even video.

Basically, more than anything, Bluetooth is a replacement for USB: some say that while 802.11 wireless networking is wireless Ethernet, Bluetooth is wireless USB.

Not Just for Computers.

Part of the power of Bluetooth is that it isn’t just used to connect things to computers — it can be used to connect almost anything to anything else, if both things are Bluetooth-enabled and recognise each other.

Mobile phones, in particular, take advantage of this. Hands-free headsets often use Bluetooth to communicate with the phone. Some cars, for example, now have on-board computers that will connect with a Bluetooth phone and allow you to make hands-free calls, regardless of where the phone is in the car (even if you’ve left it in your bag in the trunk!)

On top of that, of course, Bluetooth devices can communicate with each other. This has led to some people sending messages from their Bluetooth PDAs to others in close range — not an especially useful feature, but quite fun. This is called ‘bluejacking’, and the first recorded instance of it was a man who sent a Bluetooth message to another man’s Nokia phone while they were in a bank together. What did the message say? ‘Buy Ericsson’.

Since then, it has become possible to send images by bluejacking, and it is widely believed to be the newest advertising medium — yes, it lets billboards send messages to your phone, a practice known as ‘bluecasting’. Whether you think that’s cool or annoying, of course, is your choice.
