The UAA, or Universally Administered Address, is the most commonly used type of MAC address. This address is assigned to the network adapter when it is manufactured. The first three octets define the manufacturer, while the second three octets vary and identify the individual adapter. All network adapter manufacturers have their own code, called the Organizationally Unique Identifier (OUI).

Which portion of the IP address 175.124.35.4 represents the host?

depends on the subnet mask ie/ 255.255.255.252 which would mean 175.124.35.0,4,8,12,16etc etc are networks and 175.124.35.1 & .2 are hosts. .3 is the broadcast address for that subnet.


Is 24 bit block a better addressing scheme in computer networking than a 16 bit block?

There is nothing inherently "better" about the 24-bit block address space. If by "better" you mean "able to contain more addresses," then yes. 24-, 20-, and 16-bit network ranges are also known as class A, B, and C, respectively, and refer to ranges of IP addresses. Every device that directly accesses the internet has a unique IP address. IP addresses are commonly represented as a set of four numbers (called "octets") separated by periods, e.g. "145.94.112.18". Each of the numbers can be in the range of 0-255, and some sets of numbers have special meanings. The range of IP addresses is divided up into three classes based on the first octet. If the first octet is from 0-127 it's class A, 128-191 is class B, and 192-223 is class C. The octets of an IP address are divided up into a network portion and a host portion depending on what class it is. In class A addresses, the first octet is the network portion and the remaining three are the host portion. For class B, it's two-and-two, and for class C the first three are network and the remaining one is host. What does this network/host division mean? Generally, large entities (such as a company) are assigned a single network block of IP addresses. For instance, IBM is in control of the 9.0.0.0 network block. This is a class A address, meaning that the network portion is 9 and the rest is the host portion. IBM can divide this space up (using a technique called subnetting) any way it sees fit. Every computer within IBM would have a different ip in the 9 network, e.g. 9.4.109.10, 9.212.34.88. A class A (or 24-bit) block address has three octets it can use to create different IP addresses, such as "9.0-255.0-255.0-255". A class C (or 16-bit) block address has only one octet it can use to create different IP addresses, such as "192.168.1.0-255". You can clearly see that a class C block address contains less potential addresses than a class A or B block address. This doesn't make class C addresses any worse than class A ones, though. A small business (or a home network) doesn't need a million different IP addresses, so a 16-bit block address is perfect for them and if they had a class A or B all those numbers would be wasted.

What do you mean by ip address?

An "Internet Protocol Address" uniquely identifies a node on the Internet. Some IP address ranges are reserved for LAN use and do not appear on the full Internet WAN, allowing local nodes to actually have the same IP address but not conflict (this increases the number of allowable nodes without having to expand the size of an IP address). The original IP address was defined to be 4 bytes (octets) long, however the Internet eventually outgrew this and an alternate expanded IP address defined to be 6 bytes (octets) was defined to support the new nodes.

What is class a or class b mean in commercial language?

Class A are networks from 0.0.0.0/8 to 127.0.0.0/8, each distinguished by only the first octet of the IP address. There are 128 Class A networks (several of which are not in Internet use), each capable of handling up to 16,777,214 hosts.Class B are networks from 128.0.0.0/16 to 191.255.0.0/16, each distinguished by the first two octets of the IP address. There are 16,384 class B networks, each capable of handling up to 65,534 hosts.IP addresses no longer use classful addresses on the public Internet.
