What is register addressing mode?
Register mode: In register addressing the operand is placed in one of 8 bit or 16 bit general purpose registers. The data is in the register that is specified by the instruction. Here one register reference is required to access the data. Example: MOV AX,CX (move the contents of CX register to AX register)
Why loopback interface is used?
The loopback interface is used to identify the device. While any interface address can be used to determine if the device is online, the loopback address is the preferred method. Whereas interfaces might be removed or addresses changed based on network topology changes, the loopback address never changes.
What does IP 0.0 0.0 mean?
In Internet Protocol version 4, the address 0.0. 0.0 is a non-routable meta-address used to designate an invalid, unknown, or non applicable target. In the context of routing, 0.0. 0.0 usually means the default route, i.e. the route which leads to ‘the rest of’ the Internet instead of somewhere on the local network.
What is the use of 0.0 0.0 IP address?
In the Internet Protocol Version 4, the address 0.0. 0.0 is a non-routable meta-address used to designate an invalid, unknown or non-applicable target. This address is assigned specific meanings in a number of contexts, such as on clients or on servers.
What is 255.255 255.255 used for?
255.255. 255.255. 255.255 is a special broadcast address, which means “this network”: it lets you send a broadcast packet to the network you’re connected to, without actually caring about its address; in this, is similar to 127.0. 0.1, which is a virtual address meaning “local host”.
What destination adress is 255.255 255.255 for?
255.255. 255.255 – Represents the broadcast address, or place to route messages to be sent to every device within a network. 127.0. 0.1 – Represents “localhost” or the “loopback address”, allowing a device to refer to itself, regardless of what network it is connected to.
Is 255.255 255.255 IP address valid?
No, it is not possible to have any source 255.255. 255.255 as IP Address because this IP Address is already reserved for the broadcast address.
What is a 255.255 255.255 subnet mask?
A network with a subnet mask of 255.255. 255.255 puts each device inside its own subnet, forcing them to communicate with the router before communicating with any other device.
What does 255.255 255.0 tell a router?
Originally Answered: What does the subnet mask 255.255. 255.0 tell a router? It simply says that packets that match the LAN of the router based on the router’s LAN IP address and subnet mask should just go directly on the LAN, without considering forwarding the packets somewhere else.
Why is subnet mask always 255?
IP Address and Subnet Mask The 32 binary bits are divided into the host and network sections by the subnet mask but they are also broken into four 8-bit octets. The range of values in decimal is 0 to 255 because that represents 00000000 to 11111111 in binary.
