In classes A, B, and C,if the hostid is all ls,the address is called a direct broadcast address. It is used by a(2) to send a packet to all hosts in a specific network. All hosts will accept a packet having this type of destination address. Note that this address can be used only as a (3) address in an IP packet. Note also that this special address also reduces the number of available hostid for each netid in classes A,B，and C． In classes A, B, and C, an address with all ls for the netid and hostid (32bits) define a (4) address in the current network.A host that wants to send a message to every other host can use this address as a destination address in an IP packet. However, a router will block a packet having this type of address to confine the broadcasting to the (5) network. Note that this address belongs to class E.

How We Form First Impression
1
We all have first impression of someone we just met. But why Why do we form an
opinion about someone without really knowing anything about him or her aside
perhaps from a few remarks or readily observable traits.
2 The
answer is related to how your brain allows you to be aware of the world. Your
brain is so sensitive in picking up facial traits, even very minor difference in
how a person’s eyes, ears, nose, or mouth are placed in relation to each other
make you see him or her as different. In fact, your brain continuously processes
incoming sensory information-the sights and sounds of your world. These incoming
"signals" are compared against a host of "memories" stored in the brain areas
called the cortex system to determine what these new signals "mean".
3 If you see someone you know and like at school, your brain says
"familiar and safe". If you see someone new, it says, "new potentially
threatening". Then your brain starts to match features of this stranger with
other "known" memories. The height, weight, dress, ethnicity, gestures, and tone
of voice are all matched up. The more unfamiliar the characteristics, the more
your brain may say, "This is new. I don’t like this person". Or else. "I’m
intrigued". Or your brain may perceive a new face but familiar clothes,
ethnicity, gestures-like your other friends; so your brain says: "I like this
person." But these preliminary "impressions" can be dead wrong.
4 When we stereotype people, we use a less mature form of thinking (not unlike
the immature thinking of a very young child) that makes simplistic and
categorical impressions of others. Rather than learn about the depth and breadth
of people-their history, interest, values, strengths, and true character-we
categorize them as jocks, geeks, or freaks,
5 However, if we
resist initial stereotypical impressions, we have a chance.to be aware of what a
person is truly like. If we spend time with a person, hear about his or her
life, hopes, dreams, and become aware of the person’s character, we use a
different, more mature style of thinking and the most complex areas of our
cortex, which allow us to be humane.
