LILIK PRASETIO NUGROHO :
1. The Differenthings between BaseBand and BroadBand in Coaxiakcable :
BaseBand is all kind of cable transmission digital (with 50 ohm)
BroadBand is all kind of cable transmission analog (with 75 ohm)

2. What the function Of DNS :
DNS is created for over came the conflict in the hostmane which often happened if name host along with IP Address who is not Set with centralizationed. DNS is using for mapping host name and destination email to IP address.

KURNIASIH RAMADHANI :
1. What is the meaning about subbnetting ?
subnetting is a technique that allows network administrators to exploit 32 bit IP addresses are available with more efficiently.

2. What is the meaning about IP?
Ip protocol is TCP / IP the appropriate with the third layer in the OSI networking model. Set ip addressing, as well routing. Like post services, assign IP addresses so that the address has a structure, enables the easy routing -networking similar to the sorting of letters. IP also stated that each workstation must have a unique IP address to avoid the confusion when trying to send data to that address.

1.  Give examples of subnetting and calculations?

answer:

Calculation of subnetting can be done in two ways ie binary is relatively slow and the special way faster. Writing an IP address is usually 192.168.1.2. But sometimes written with 192.168.1.2/24. Penjelasanya is that the IP address 192.168.1.2 with a subnet mask of 255.255.255.0. Why be like? Intent / 24 taken from counting that 24-bit subnet mask diselubung with a binary 1. Or in other words, the subnet masknya is: 11111111.11111111.11111111.00000000 (255.255.255.0). This concept is called CIDR (Classless Inter-Domain Routing) which was first introduced in 1992 by IEFT. Virtually all the questions about subnetting will range in four problems: Number of Subnet, Number of Hosts per Subnet, Block Subnet, and Host-Broadcast Address.

2. Give examples of static and dynamic routing?
answer:

Static routing, a routing table creation manually. Static routing is useful for simple networks where routers only use a few pieces only and is useful for saving bandwidth usage. Manually point is if my friend as a network administrator,

1.what IP addres????

anwers:

"IP" stands for Internet Protocol, so an IP address is an Internet Protocol address. What does that mean? An Internet Protocol is a set of rules that govern Internet activity and facilitate completion of a variety of actions on the World Wide Web. Therefore an Internet Protocol address is part of the systematically laid out interconnected grid that governs online communication by identifying both initiating devices and various Internet destinations, thereby making two-way communication possible.

2.explain about the class of ip addressing class?
anwers:

• The first bit of class A IP address is 0, with a length of 8 bits net ID and host ID 24 bits long. So the first byte of the IP address class A has a range of 0-127. So in class A there are 127 networks with each network can accommodate about 16 million hosts (255x255x255). Class A IP address given to the network with a very large number of hosts, 
• Two bits of a class B IP address is always set to 10 so the first byte is always a value between 128-191. Network ID is the first 16 bits and 16 bits are the host ID so that if any computer has the IP address 167.205.26.161, the network ID and host ID = 167 205 = 26 161. On. Class B IP address has IP range from 128.0.xxx.xxx to 191.155.xxx.xxx, which amounted to 65 255 network by the number of hosts per network host 255 x 255 or about 65 thousand hosts.
• Class C IP address originally used for small networks such as LANs. The first three bits of a class C IP address is always set to 111. Network ID consists of 24 bits and 8 bits of remaining host ID so it can be formed about 2 million networks with each network has 256 hosts.
• Class D IP address used for multicasting. The first four bits of a class D IP address is always set 1110 so the first byte ranges between 224-247, while the next bit is set as required using the IP multicast group address. In multicasting is not known the term network ID and host ID
• Class E IP address is not made ​​available for public use. The first four bits of the IP address of this class is set 1111 so the first byte ranges between 248-255.
