ping stands for packet internet groper. it is use for echo request and reply message to check the physical and logical connectivity of a machine on an internetwork
True.

PACKET INTERNET GROPER uses ICMP echo request and reply messages to check the physical and logical connectivity of machines on an internetwork . Hence Ping works on layer 3 of OSI model.
Create one primary partition and an extended partition with four logical drives within it.
A logical representation of one or more physical disks configured to provide redundant and/or large storage space for the system.
A logical topology depends on the way data flows within a network and the protocols used for communication, rather than the physical arrangement of devices. It defines how devices logically communicate with one another, which can differ from the actual physical connections. Factors influencing logical topology include network protocols, addressing schemes, and the intended data paths. Common types of logical topologies include bus, ring, and star configurations.
logical and mac
A logical topology shows how a network is configured logically rather than physically. The main difference is that you could have 10 routers, 25 switches, and 5,000 computers in a logical topology and it doesn't matter where they are on the screen, it matters how they are connected to one another.
The network layer is designated as Layer 3 in the OSI (Open Systems Interconnection) model. It is responsible for routing data packets between devices across different networks, handling logical addressing, and determining the best path for data transmission. Protocols commonly associated with this layer include Internet Protocol (IP) and Internet Control Message Protocol (ICMP).
You can block logical ports to invaders and make your computer invisible to others on the Internet by installing
A mapping from logical address to physical address is essential for memory management in computer systems, as it allows the operating system to abstract the physical memory layout from applications, enabling efficient memory allocation and protection. This mapping is typically achieved through mechanisms such as paging and segmentation, which break down memory into manageable units. Protocols involved in this process include the Memory Management Unit (MMU) protocols, which translate logical addresses generated by programs into physical addresses in RAM, and the use of page tables to keep track of the mapping. Additionally, virtual memory protocols allow systems to use disk space as an extension of RAM, further enhancing memory efficiency.
