WINS is the acronym for Windows Internet Name Service, while DNS is the acronym for Domain name system. There are some differences between WINS and DNS. WINS is a service that is concerned about changing IP address, it is usually present in devices that have Windows operating system. And this means, WINS does not stand on its own because it will first have to depend on Windows.

Whereas, DNS is majorly a system for network devices and it is used for IP address that does not change, unlike what we have WINS. DNS operates on its own without having to depend on any operating system. Another thing is, while WINS supports IP addresses like DHCP, DNS does not support it. Finally, WINS is developed to give details about NetBIOS names to IP addresses, DNS does not support that, but rather resolves host names to IP addresses.

A lot of people who love using gadgets will probably know the difference between the two. Bluetooth will allow different gadgets to connect with each other so that they can send images and other media files easily. The WiFi is something that gadgets can connect to so that they will also be connected to the internet. The range of the two is also different from each other.

WiFi is known to have a longer range because it can have a range of up to 100 meters. The power consumption of the Bluetooth is low and your gadget will not be too affected if you would use this often. The WiFi power consumption is high and this is why people would need to charge their gadgets often to stay connected.

The IP address is a network adaptor to other devices on the network, or answer A. The IP address is what address your computer or phone uses to get online. If you’ve ever seen something like NCIS or Criminal Minds, you know that it is often used to track hackers in these programs. This is harder to do in real life, since there are firewalls, privacy laws, subpoenas, and other items needed.

Regardless of what the IP address is used for as part of law enforcement, it’s simply the address of a specific device on a network. My father has used IP addresses to cut off wifi on our devices at a certain time because he wanted to cut off our internet so we would sleep, for example.

TCP refers to the Transmission Control Protocol. This has to do with the traffic on the network and with TCP it can go in different directions. UDP is very similar to TCP in that it controls the conversations among the networks.

However, the difference between the two is that UDP which stands for User Datagram Protocol is easier and is not connected compared to the TCP. Both systems control how messages are sent and received on the Internet.

However, with UDP it is not connected so that once the message or packet is sent, it is over. TCP and UDP have port numbers attached to them and the purpose for having these port numbers is to track the different conversations crossing the network at the same time.

WLAN stands for Wireless Local Area Network. This is a type of network that will make sure that devices will be connected and that the various devices will have the ability to communicate properly. LAN stands for Local Area Network and the main difference between the two is how they allow devices to connect.

LAN makes sure that devices are connected with the help of the Ethernet while WLAN makes devices connect and communicate with the use of WiFi. WLAN is the wireless version of the LAN and is usually preferred by a lot of households and commercial spaces now because of the benefits that it can provide over the cabled LAN. Some routers can offer both WLAN and LAN connections.

Transmission Control Protocol is also known as TCP. It allows for the connection through the Internet or network so that data can be transferred usually through an app. The application program plays an important role in regard to the connection and transmission of data. There are several characteristics that play a part of TCP. These include the source port, destination port, sequence number, acknowledgement number, data offset, flags and urgent pointer.

All of these things play a part in the success of making sure that the Transmission Control Protocol works. There are three phases in the protocol and state changes. The state changes include listen, syn-sent, syn-received, established, fin-wait1, fin-wait2 and close-wait. The others are closing, last-ack, time-wait and closed.

The answer to this is B. The coaxial cable is known to provide the protection that is needed against the EMI when data transmitting is taking place. This electrical cable is protected because of the insulating layer. Take note that there are different coaxial cables that are available.

There are some that are known to be better than the others. It is best that you will check the different brands available before you pick the one that you need. There are moments when it can be purchased as a part of a package. The BNC is responsible for connecting the coaxial cable.

WLAN is the acronym for Wireless Local Area Network, while WI-FI is the acronym for Wireless Fidelity. Both technologies are used in transferring data or files without the ancient method of data connection and transmission via cable. This means, no wire or cable is needed when Wi-Fi and WLAN are in use. WLAN is a type of network used by a computer which covers only a small area but gives a wireless means of transferring data.

Different computers within that place can be connected to a central system or computer, or other devices like scanner, printer, etc. Wireless LAN is based on IEEE 802.11as the standard for devices. Wi-Fi, on the other hand, is just a brand name for different types of devices that use wireless LAN. Wireless is also based on the same standard as Wireless LAN, i.e. IEEE 802.11. The simple thing is that any device using Wi-Fi is already using wireless LAN.

When it comes to your WiFi, you would like to know all the possible details. As much as possible, you want your WiFi to be strong so that you can connect to the internet easily. The WiFi repeater and extender are very similar to each other.

Their main goal is to make sure that WiFi will spread in a larger area around your home. A WiFi repeater or extender will have the ability to make sure that all parts of your home will be connected to the internet. There are times when you do not need repeaters or extenders anymore. All it takes is to change the location of the WiFi and it will already be easy to connect.

A lot of people in the data communication industry use the layered OSI reference model because it “divides the network communication process into smaller and simpler components, thus aiding component development, design, and troubleshooting,” or answer 1 (which should be answer A to fit with the rest of the answers’ labels). Think about it.

If the network was this huge, bulky thing, troubleshooting would take forever. With smaller components, you can find the one that’s having problems and work on that one without having to do a lot of trial and error to find the problem area.

It’s the same reason you do as much as you can to figure out what’s going wrong when you’ve lost something; you are trying to find where you lost it.
