This assignment has four questions for a total of 80 marks. Answer all the
questions. Each question carries 20 marks. Rest 20 marks are for viva voce.
Q1. Given the network address 132.21.0.0, find the class, the block,
and the range of the addresses.
A1.The class of the network is B and the addresses range from 132.21.0.0 to
132.21.255.255.
Explanation:
Network Address
A network address denotes the specific location where a resource is placed on the
internet. Every website has a unique network address and each network address is
classified into classes.
Furthermore, each class has a particular range of addresses:
Class of the Network
There are a total of five classes of networks from A to E.
Network address 132.21.0.0 has a class B because the first byte is between 128
and 191.
Range of the Network Address
The given network address has a network ID of 132.21. The addresses will start from 0
and will go on to 255. That's why the addresses range from 132.21.0.0 to
132.21.255.255.
Q2. Compare 3G, 4G and 5G network architectures.
A2.
, 1. THIRD GENERATION (3G)
The 3G standard utilises Universal Mobile Telecommunications
System (UMTS) as its core network architecture. 3G network
combines aspects of the 2G network with new technologies and
protocols to deliver a significantly faster data rate. By using packet
switching, the original technology was improved to allow speeds
up to 14 Mbps. It used Wide Band Wireless Network that
increased clarity. It operates at a range of 2100 MHz and has a
bandwidth of 15-20 MHz. Some of the main features of 3G are:
Speed of up to 2 Mbps
Increased bandwidth and data transfer rates
Send/receive large email messages
Large capacities and broadband capabilities
International Mobile Telecommunications-2000 (IMT-2000) were
the specifications by the International Telecommunication Union
for the 3G network; theoretically, 21.6 Mbps is the max speed of
HSPA+.
2. FOURTH GENERATION (4G)
The main difference between 3G and 4G is the data rate. There is
also a huge difference between 3G and 4G technology. The key
technologies that have made 4G possible are MIMO (Multiple
Input Multiple Output) and OFDM (Orthogonal Frequency
Division Multiplexing). The most important 4G standards are
WiMAX and LTE. While 4G LTE is a major improvement over 3G
speeds, it is technically not 4G. What is the difference between 4G
and LTE?
