What is the difference between an Ethernet Address and an mac address?
Ethernet address is really not a good term to use. I think you mean a MAC address. A MAC address is given to any device that accesses the internet. Such devices include WiFi cards, modems, and routers. These are only used by networks that devices connect to, and not by websites. They can be used for filtering and identifying devices on a network.Ip (Internet Protocol) addresses are assigned to networks (one per network) by an ISP (Internet Service Provider) such as Comcast. These are sent to everything you interact with online, so that your network, rather than your computer, is identified.Now there are two kinds of Ip addresses: internal and external. Internal are used by your network to identify each device that connects to it. External Ip's are assigned by your ISP to identify you to the world. I explained the difference more in-depth in another answer, which is right here:What_is_the_difference_between_an_Ip_address_and_a_http_address
Ip address is a hardware or software or code or a program?
An IP address is a 4-byte (32-bit) number, used to identify a computer. This is often configured into the computer; or the IP address of a computer is handed to the computer, at startup, by a DHCP server. It is not generally coded into hardware, although certain networking equipment might have, in hardware, a default address such as 192.168.0.1 (this is a private address). For the most part, the IP address is none of the options you specify - it is neither hardware, nor software; it is information used by the hardware and software.
Describe the structure of an ip address?
IP addresses identify devices on the internet and other TCP/IP networks. They comprise four numbers separated by periods. The first part of an IP address identifies the network, and the last identifies the host. MAC addresses are used only for communication within a local network.There are four octects in a IP address. IP address can be assigned, MAC address are embedded in the (NIC)IP address is a 32 bit address consisting of a series of four 8 bit numbers separated by periods. An IP address identifies a computer, printer, or other device on a TCP/IP network such as the internet or an intranet.Mac address is a unique 42 bit address permanently embedded in a NIC and identifying device on a LAN.Source: CompTIA A+ Guide to Hardware by Jean Andrews (page 468)An IP address is a 32-bit address comprising a series of four 8-bit numbers separated by periods. An IP address identifies a computer, printer or other device on a TCP/IP network such as the internet or intranet.
What stores the data that the CPU actively uses?
The CPU registers. If the data is too large to physically store in a register, the register stores the memory address containing the data instead (usually a RAM address but could be any address in the physical address space, including ROM and graphic memory). On a 32-bit system, data registers need to be at least 32-bits long in order to store memory addresses.
Why would the ping command accept the name yahoo.com instead of an actual IP address?
This is possible because of what is called Domain Name Resolution (DNS). Your computer sends a lookup request for 'yahoo.com' to a DNS server, which resolves the domain name into it's IP address.
Why is class A IP address not suitable for a local area network?
Class A IP addresses are not suitable for local area networks (LANs) because they are designed for very large networks, supporting up to 16 million hosts per network. The vast address space is inefficient for small networks, which typically require far fewer IP addresses. Additionally, using Class A addresses in a LAN can lead to routing inefficiencies and increased complexity. Instead, Class C addresses, which support up to 254 hosts, are more appropriate for most LAN configurations.
What is the maximum number of bits that can be borrowed with class b?
The maximum number of host bits that can be borrowed from a class A address is 22 (technically you could borrow 23 but the resulting network would be useless). A class A address uses 8 bits for its network address and 24 bits for its host addresses. Class A uses a subnet mask of 255.0.0.0 You can only borrow 22 bits (instead of 24) because a valid network requires 4 addresses: A network address, two host addresses and a broadcast address. These networks would result in 30 bits used for the network address and 2 bits used for the host addresses. These networks use a subnet mask of 255.255.255.252
If you use an adsl modem and connected to two computer is your ip same on both computers?
No, each computer must have a different IP address. The IP addresses have to be in the same subnet between themselves, and in the same subnet as the ADSL router (or modem); I won't explain subnets here, but usually having the same numbers for the first 3 parts of the IP address is enough. For example, if the ADSL router has the IP address 10.0.0.1, your computers might have addresses 10.0.0.2 and 10.0.0.3. If you need to add a third computer, give it the IP address 10.0.0.4If the first computer has a different IP address - and it works - replace that, instead. For example, if the computer has IP address 172.16.0.2, assign the address 172.16.0.3 to the next computer.
What would happened if there was not DNS in internet?
Instead of having nice, easy to read, web addresses (google.com), you would have to remember a computer's IP Address (74.125.224.72). Basically, DNS tells yours computer that when you enter Google.com, it needs to connect to 74.125.224.72. It's like remember a houses address instead of it's latitude and longitude. DNS is just a system that relates the two.
How does IP addresses work?
The simplest answer is to compare an IP address with a phone number: Each computer get assigned a unique number, the IP address, and any computer in the world can contact any other computer as long as it knows the address. You can look up who owns an IP address and its approximate geographic area in an IP database, see related link for an example. People normally don't use IP addresses, we use domain names like "google.com" instead. Computers use a service called a DNS (Domain Name Server) to look up the IP address associated with a domain name. See related link for more on IP addresses. IP means Internet Protocol.
What country has a CA at the end or its web address?
Austria is the country with .at web addresses. Australia, however, has .au addresses instead.
Why is there so much of those ID usernames?
Because they are not registered. Supervisors and CA's see IP addresses instead, but regular contributors only see a computer-generated alias for the IP address, apparently for liability reasons.
A is the name of computer and used in places of its ip address?
In networking, "A" typically refers to an "A record" in the Domain Name System (DNS), which maps a domain name to its corresponding IPv4 address. This allows users to access a computer or server using a human-readable name instead of a numerical IP address. By using A records, networks simplify the process of connecting to devices and services on the internet.

What is the name resolution?
Name resolution is a function of DNS (Domain Name System). Computers do not use names to communicate with each other in TCP/IP networks or on the Internet. Instead, they use IP Addresses. An IP Address is a series of numbers (IPv4). For example, the IP Address for this site (wiki.answers.com) is 67.196.156.25. That is not exactly a number that most humans will find easy to remember. In order to be able to type http://wiki.answers.com/ into your browser and get to the site successfully, your computer has to contact a DNS Server. The DNS Server will take the name you pass it, and return an IP address. Your computer will then use this IP Address to communicate with the remote web server, and then your browser can display the page. Without DNS, you would have to know the IP address of every server you wanted to connect to.
What is 169.255.255.0?
The IP address 169.255.255.0 is part of the larger address block designated for link-local addresses in the Internet Protocol version 4 (IPv4). This specific address is technically reserved and is not typically assigned to hosts on a network. Instead, link-local addresses are used for communication within a local network segment. In practice, addresses in the 169.254.0.0/16 range are automatically assigned to devices when they cannot obtain an IP address from a DHCP server.
Does every computer system has an IP address?
No, not all computers have an ISP (Internet Service Provider). An ISP is the service provider that you pay to get internet access from. Seeing as this is an optional part of owning/using a computer, not everybody has one. If instead of "ISP address" you meant "IP address", not all computers have this either. An IP (Internet Protocol) address is given to you by your ISP. So, going back to how having an ISP is optional, not all computers have a set IP address.
