Why does a switch need a default gateway address configured?
There isn't one. The switch only knows about MAC addresses, and the default gateway isn't one of those addresses.
How many addresses are in an address book?
many addresses
This layer specifies how addresses are assigned and how packets of data are forwarded from one network to another toward the destination?
data link layer
How millions of computers are addressed with just 32 bits?
Internet addresses of computers are currently covered by Internet Protocol version 4 (IPv4), which has a 32 bit address space.Imagine you had only 1 bit long addresses. Then you could have only 2 different addresses - address 0 and address 1. But if you had 2 bit long addresses, you get 4 possible addresses - 00, 01, 10, 11. If you had 3 bit long addresses, you would have 8 possible addresses - 000, 001, 010, 011, 100, 101, 110, 111. Every time you add a new address bit, you double the number of addresses possible.1 bit = 2 addresses2 bits = 4 addresses3 bits = 8 addresses4 bits = 16 addresses5 bits = 32 addresses...Since each address bit doubles the number of possible addresses, a 32 bit address space covers 232 possible addresses, or over 4,000,000,000. And this is only for unique addresses that the whole world can use; many computers are in private networks (inside corporations, for example) and do not need an external IPv4 address. They talk to the outside world through a few routers which DO have IPv4 addresses. So a company might have tens of thousands of computers, but only a few dozen IPv4 addresses that are assigned to the routers they have connected to the internet.Even so, all 4,000,000,000 of the IPv4 addresses have finally been allocated and will be used up over the next several months. This means that the internet will need to migrate to a newer addressing version, IPv6. IPv6 uses 128 bit addressing. 2128 is about 3.4x1038 addresses. That's 3,400,000,000,000,000,000,000,000,000,000,000,000,000 addresses. They should last us a while.
Which address on a PC does not change even if the PC is moved to a different network?

Device that has two IP addresses is?
gateway
How many Mac addresses are possible?
This 48-bit address space contains potentially 248 or 281,474,976,710,656 possible MAC addresses.
What is used to map IP addresses to corresponding domain names?
DNS
Why does a switch need a default gateway address configured?
There isn't one. The switch only knows about MAC addresses, and the default gateway isn't one of those addresses.
Is it possible to have a private and a public network address at the same time?
Using NAT (NETWORK ADDRESS TRANSLATION) can make it possible to connect to Internet with Public IP Address at the Internet Gateway while Computers internally will use Private range of IP Addresses.
How can you distinguish memory addresses from you IO port addresses?
Not possible, both are numbers.
What is the answer for 6.5.7 packet tracer-assigning addresses?
Ip address is 10.0.1.0 Gateway is 10.0.1.254 if not Try this update 01/30/2014 IP Address: 10.0.1.28 Subnet Mask: 255.255.255.0 Default Gateway: 10.0.1.254
Which statement accurately describes routing between VLANs when the default gateway addresses of the VLANs are applied to physical interfaces?
chuk norris
What is a possible reason that host a and host b are unable to communicate outside the local network?
Because they need a device to communicate with a distant network through. These devices are called gateways, and are normally routers. The hosts on a segment need to have knowledge of the gateway device in order to communicate outside the segment. In most environments, the local network will have an internal addressing scheme, one that is not routable on the internet, so there needs to be a device that can translate the internal addresses (non routable on the internet) into external addresses (routable on the internet). Of course this device needs to be connected to both the internal network and the external network to be able to send traffic between them.

Your computer sends but does not accept packets How can you get it to receive packets?
When a computer is able to send but not receive packets, it means it has wrong DNS server addresses and gateway. Check out the correct addresses in order for the computer to send and receive packets.
