A host on a network needs to broadcast an ARP request to advertise its Mac address. The networking world is very chatty in nature and when a new network host is available it immediately broadcasts its Mac address as with a ARP message.
Also when a particular network host needs to send a data packet to another network host available in the same LAN whose Mac address is unknown, the first network host sends out a ARP message requesting for the destination network hosts MAC address.

When do you need a grand jury?
YOU (individually) don't NEED and can't request, a Grand Jury. Grand Juries are convened at the direction of the government, not at the request of the defendant. A grand jury decides if there is enough evidence to stand trial.
What is the purpose of an arp request?
The purpose of an arp request is to map an IP address to a MAC address for the link layer to transmit a packet. For example, ARP will get a request to map 1.2.3.4 to a MAC address 12:fd:23:gf .Then ARP will cache the address mapping that next time an arp request doesnt need to happen
What are three important reasons to establish a network baseline?
to determine which areas in the network are underutilized or overutilizedto determine the performance of the network during the normal hours of operationto determine what thresholds should be set for the devices that need to be monitored
What is a computer network and why it is useful?
A computer network - is two or more computers linked together. It's useful - because computers can communicate 'live' with each other. Additionally - If computers are networked, you only need one printer. All the computers on the network 'share' the printer between them.
Can you get a job in the criminology area in some other country if I am not from that country?
Anything is possible, but you would need a work visa first and would need to have good relevant qualifications and some good experience that the host country needed.
Calculating network host and broadcast address?
To calculate Network address you should assign "0" " Zero" for Host portionEx. 192.168.157.6/24Since the above IP is Class C last Octet will be the host partThis will be shown in binary as11000000.10101000.10011101.00000110.00000000Then Network address will be 192.168.157.0To find the broadcast IP you need to add "1" Once for host partIf we take Same IP11000000.10101000.10011101.00000110.11111111The Broadcast IP will be 192.168.157.255
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.
What is the difference between broadcast design and motion graphics?
They are kind of similar. Well basically Broadcast Design is as its name says to be broadcasted by a television network. A large portion of broadcast design is known as "branding" for television channels and programs. Motion graphics is graphic design applied to animation, it doesn't need to be broadcasted on a tv network.
What factors do you need to consider when implementing VoIP within an existing network?
You have to consider the size of phone network, call duration, usage and speed of the internet which will host as a communication network.

What is host for this 255.255.255.192?
You have given a subnet mask; it has nothing to do with hosts. You would need to supply the network number.
Discuss the need or lack of need for a network layer OSI layer 3 in a broadcast network?
The network layer is responsible for addressing nodes in a logical way. It is also responsible for making decisions on routing a packet from one network to another. In a broadcast network, routing is not needed. A transmission from any attached station is received by all other attached stations. Other functions,such as sequencing, flow control, error control, can be done at layer 2. The MAC sublayer is responsible for addressing across the LAN. With the Data link layer and its sublayers (MAC & LLC), no network layer is needed.
What is a good way to contain network traffic to a certain area in a network?
One of ways to do that is to use VLAN, but you need switch or router supporting. Also just single router without VLAN can separate networks isolating broadcast and collision domains. Some switches can limit broadcast domains too but they are rather expensive.
How do you know how many bits represent the network portion and the host portion?
When we express an IPv4 network address, we add a prefix length to the network address. The prefix length is the number of bits in the address that gives us the network portion. For example, in 172.16.4.0 /24, the /24 is the prefix length - it tells us that the first 24 bits are the network address. This leaves the remaining 8 bits, the last octet, as the host portion.
What is unique about network IP addresses?
An IP address must be unique within a LAN; the combination of the network and host portion must present a number that is not duplicated anywhere else in the network. Outside of a LAN the IP addresses do not have to be unique, except that the network id portion can only be used by the organization that owns the IP network address. The host portion does not need to be unique across all LANs within an enterprise network.
If a guy tells you he accepted your friend request on Facebook loudly does he mean something?
If he did it in front of class. Probably. Accepting friends request online is the norm these days. So his need to broadcast it to the whole class is him bragging that you and him are definitely more than acquaintences.
When DNS is installed on a server what service can DNS perform for users of client computers accessing network resources?
DNS stands for Domain naming system. it basicly translate ip address to host names and host names to ip address. If you use it on a local network it allows you to use your own naming conventions for your local subnet . Which helps to work easily in huge network need to remember only host names in network.
