What does a basic communications system consists of?
A basic communications system consists of---------- 1.Two computers, one to send and one to receive data 2.communications devices that send and receive data 3. a communications channel over wich data is sent 4.All of the above
Mail and information function in hotel?
In a hotel if you need to get mail you can often have it sent to the front desk. If you need email or other such information or function, hotels generally offer Wi-Fi internet.
What do you mean by communication media?
The meaning of communication media is data or information that is sent using some source of media. These media types are often radio broadcasts, televisions airwaves, internet or telephones.
What is a place where letters can be sent called?
Letters can be sent to an address.
How would you view sent messages on Facebook?
When on the 'Inbox' page on your left there are three tabs: -Messages -Updates -Sent Click on 'Sent'.
What is the default time BPDUs are sent and received by switches?
2 seconds
Why can't you set up DHCP on a hub?
Hubs are dumb devices that operate at the hardware layer of the network only. They basically function like an old party line phone system where everything that gets transmitted is sent to every port on the hub and all the connected devices ignore transmissions not sent to them. Hubs are simply not sophisticated enough to offer services and protocols such as DHCP, DNS or any other network protocols themselves. Devices that do offer DHCP are typically routers, some layer 3 switches or servers.
What is an internetworking device?
A device that allows information to traverse different networks. Generally these are Layer 3 devices and a router is a perfect example of an internetworking device. A (basic) switch is NOT an internetworking device because information cannot be sent to a different network.
How do you calculate packet delivery ratio in MANET?
I think PDR= Packets Received / Packets Sent Packets sent/received values should be from same layer. i.e. all from application layer or network layer...etc
Which layers ensures data is received in the order it was sent?
Transport (Layer 4)
What is addressable devices?
This is an digital device that can respond to messages sent from many similar devices. For example, computers in a network.
What is the name of the satellite that monitors the ozone layer?
There are various satellites which monitor the ozone layer. Most of these are sent by NASA.
How does a missile explod?
A smaller missile will usually detonate by means of an electrical impulse sent by a contact device, while larger cruise missiles and nuclear devices often contain sensing devices that are programmed to detonate when they are at a certain distance from the target. Tiny devices such as mortar shells and RPG rounds usually have blasting caps that are impact sensitive.
What layer does a Wireless Acess Point utilize?
By layer, I am assuming you are talking about either the OSI 7 layer model or the TCP/IP 4 layer model. A router is fairly complex and provides services at 3 of the OSI model layers and 2 of the TCP/IP model layers. In the OSI model a router handles the Network Layer. In the TCP/IP model this layer is called the Internet Layer. It changes logical addresses to machine addresses and then finds paths (routes) to the destination node. It may break up the data into smaller parts for transmission or reassembling data received. There is no verification of successful transmission. A router also maintains a list of nodes that it is immediately connected to (computers, smart TV, Xbox, ...). Data segments from higher layers is converted to datagrams. Datagrams received from lower layers are translated into data segments. The router establishes a Data Link Layer to all devices it is immediately connected to . This layer provide reliable communication and can detect and sometimes correct errors at the Physical Layer. The datagrams received from the Network Layer are converted into data frames and sent to the Physical layer. Data frames received from the physical layer are converted into datagrams and sent to the Network Layer. The router also provides Physical Link Layer connections to all devices immediately connected to it. This is physical and electrical characteristics of the communication media (wire, fiber, wireless, ...). This is where the signals are negotiated like speed, timing, pin layout, voltages, ... After negotiation the physical layer is responsible for actual transmission of data over the line. Data frames received from the Data Link Layer are converted to bits and sent to the remote node. Bits received from the remote node are converted into data frames and sent to the Data Link Layer. The Data Link Layer and the Physical Layer are called the Link Layer in the TCP/IP model.
How will a packet that is sent from host A to host B be handled by the devices on the network?
C
Can an GIMP image and its layers be sent so it can be opened by the recipient so that itis workable layer by layer?
can you save as .psd?if you can then do it and send
Why are speakers output devices?
Output devices are devices that present data coming from the computer. Speakers do this by taking information that is sent to it via the sound card and outputting that information via sound.
