Physical Address is nothing but your actual real address like MAC.for that Storage device should be required.Physical Address can't never change,It is present in NIC Card.Logical Address is noting but ur IP address which is used to create client.It will change whenever change required.ThanksAm...
A logical address is like a file on the server,, with information or instructions that lead to it. A port address is an address assigned by the CPU (0-FFFF) that can be accessed for i/o read/write like RAM. Consider this analogy: Physical address - GPS coordinates: longitude / latitud...
Why default option is Yes? It’s done to avoid unnecessary reading (it’s useless to read other 7 logical sectors if first is damaged). Reading drive in physical sectors can extend heads life in case of damaged media. Also there is some d...
Physical address vs. logical address. Number of bits. Address assignment and permanence. Address formatting. A MAC address is responsible for local identification and an IP address for global identification. For example, the MAC address is only significant on the LAN to which a...
An open-source and high-performance key-value distributed storage database. It supports a variety of data types, supplementing the key-value storage such as memcached and meeting the real-time and high-concurrency requirements. RTD Containers Provides physical environments for the running of Business...
then giving it to the Post Office. The logical connection is actually made up of a lot of physical connections and processing points: trucks, possibly airplanes, sorting facilities, etc., but you don't have to care about that. The system insulates you from that complexity. Furthermore, a ...
Essentially, an IP address is a logical address used for routing data across networks, and a MAC address is a physical address used for communication locally within a single network. IP addresses operate at the third layer of the OSI model,the network layer, while MAC addresses are use at ...
1.7 We have stressed the need for an operating system to make efficient use of the computing hardware. When is it appropriate for the operating system to forsake this principle and to“waste” resources? Why is such a system not really wasteful?答：单用户系统，它应该最大化地为用户使用，一...
You can use the underscore character to tell the compiler that it should keep processing the next line as part of the current one (that is, treat multiple physical lines as a single, logical line). But having to type underscores repeatedly has always been annoying, and in fact, for years...
In CHS, the addresses of physical blocks of data or sectors on a disk are exposed and addressing is done by identifying individual blocks by their position in a track. The track itself is determined by the numbers of the head and cylinder. Thus, to address a hard drive, its C, H and...
