,Hardware addressing
Hardware addressing, also known as physical addressing, refers to the unique
identifier assigned to each device on a computer system's hardware bus, such as a
local area network (LAN) or peripheral component interconnect (PCI) bus. This
identifier, referred to as the hardware address, or MAC address (Media Access
Control address), is a 48-bit value written into the device's firmware at the time of
manufacture.
The hardware address is used by the underlying operating system to communicate
with the device, and it is also used by network protocols to route data packets over
the network. The MAC address is unique to each device and is used to distinguish
between different devices on the network.
It is important to note that hardware addressing is different from IP addressing, which
is used to identify devices on a network at the software layer. IP addresses are
assigned to devices dynamically or statically, and they are used to route data
packets over the Internet and other networks.
In summary, hardware addressing is a fundamental aspect of computer networking
and is used to identify and communicate with individual devices on a network.
Logical addressing
Logical addressing, also known as software addressing or IP addressing, is a
method of identifying devices on a network at the software layer. Unlike hardware
addressing, which uses a unique identifier built into the device's firmware, logical
addressing uses a software-based identifier that is assigned to the device.
The most common type of logical addressing used in computer networking is IP
addressing, which is based on the Internet Protocol (IP). IP addresses are used to
identify and locate devices on a network, and they are used by the network's routing
mechanism to forward data packets from one device to another.
An IP address is a unique identifier assigned to a device on a network, and it is
typically expressed as a series of four numbers separated by dots (e.g.,
192.168.1.1). There are two types of IP addresses: IPv4 and IPv6. IPv4 addresses
are 32-bit values, while IPv6 addresses are 128-bit values.
In summary, logical addressing is a method of identifying devices on a network using
software-based addresses. It is used to route data packets between devices on the
network and is essential for communication over the Internet and other networks.
