Network Layer of TCPIP model?
The network layer (Internet Layer in TCP/IP model) is the second layer of the TCP/IP model. IP (Internet Protocol), ARP (Address Resolution Protocol), RARP (Reverse Address Resolution Protocol), ICMP (Internet Control Message Protocol) and IGMP (Internet Group Management Protocol) are the protocols at this layer. http://www.omnisecu.com/tcpip/internet-layer.htm
What is the purpose of the TCPIP Network Access layer?
The purpose of the TCP/IP Network Access layer is to handle the physical transmission of data on the network, including addressing, routing, and flow control. It is responsible for converting data into signals for transmission and vice versa, ensuring that data is transmitted correctly between devices on the network.
How are computers physically connected in a network?
Computers are physically connected by a variety of mediums, including "Wi-Fi," "Ethernet," and "fiber optics." The only requirement for these connections to physically exist is that each end of the connection must have a way to interface with the medium being used over a common physical protocol. For Wi-Fi, for example, both sides must be equipped with antennas and broadcasters capable of receiving and sending signals at the proper frequencies. The OSI network model refers to these connections as the "Physical Layer", the lowest level in the model. In all cases, both ends communicating at the Physical Layer level must be using the same medium and physical signalling characteristics.
What is the rowland-molina hypothesis?
The Rowland-Molina hypothesis suggested that chlorofluorocarbons (CFCs) could deplete the ozone layer in the Earth's stratosphere. This hypothesis was significant in raising awareness about the potential environmental impact of CFCs on the ozone layer and ultimately led to the implementation of the Montreal Protocol to phase out the production and use of CFCs.
Many business computers have three distinc and world wide uniue identifiers What are they?
The three distinct and worldwide unique identifiers for business computers are typically the MAC address (Media Access Control), the IP address (Internet Protocol), and the hostname (assigned name to the device on the network).
Identify the network transport layer protocols used for Windows file sharing when the protocols are installed alone?
The network layer protocol is Trivial File Transfer Protocol (TFTP)
What is TFTP?
TFTP (Trivial File Transfer Protocol) is a lightweight file transfer protocol that is most commonly used for booting computers over a network or updating devices attached to the network.
What protocol does PPP use to identify the Network layer protocol?
Network Control Protocol is uses to identify the Network layer protocol used in the packet
The dns protocol is at what layer of the OSI model?
DNS is an application layer protocol. The application layer of the OSI model is the layer closest to the user and provides network services to the applications of the user. Examples of protocols that operate at the application layer are: DNS, FTP, TFTP, SNMP, TELNET, RLOGIN, SMTP, MIME, NFS, FINGER, BOOTP and SMB.
Difference TCP and UDP?
TCP is the protocol of network layer, It is connection oriented protocol. UDP is the protocol of network layer, It is connection less protocol.
Which network layer protocol is responsible for routing packets on the network?
The network layer is the layer that is responsible for routing packets on the network. This is the layer in which Internet protocol operates. In the seven layer OSI model, the network layer is the third layer from the bottom.
What layer of the OSI model does Internet Protocol belong to?
IP is a layer 3 (network layer) protocol used for routing
Which Transport layer protocol does TFTP rely?
TFTP uses UDP - TFTP stands for Trivial FTP, and it is called trivial because it does not check to ensure delivery, it uses UDP which makes a best-effort delivery attempt
What is the difference between network layer and network layer protocol?
A network layer refers to one of the actual 7 layers. The network layer protocol is actually the system it uses, possibly the order that the layers are done by?
What is the purpose of a tftp server?
A TFTP (Trivial File Transfer Protocol) server is used to transfer files between different computer network within a network. This type of server is meant for use with a local area network (also known as a LAN). The purpose is of TFTP is to allow people to share information between computers in a closed system environment (such as an office or school).
How does tftp overcome the limitation of using a connectionless transport layer protocol?
TFTP doesn't really overcome the connectionless transport - it doesn't have to because the idea here is transferring files with speed, not quality. It doesn't matter to the protocol is the information doesn't arrive, or arrive correctly, etc.
What network layer security protocol can secure any application layer protocol used for communication?
*IPSEC
