04 Network Layer Protocols and IP Addressing
Trending!
Internet Protocol Version 4 (IPv4) is the core protocol suite in the TCP/IP protocol suite. It works at the network layer in the TCP/IP protocol stack and this layer corresponds to the network layer in the Open System Interconnection Reference Model (OSI RM).
The network layer provides connectionless data transmission services. A network
does not need to establish a connection before sending data packets. Each IP
data packet is sent separately.
This notes describes the basic concepts of IPv4 addresses, subnetting,
network IP address planning, and basic IP address configuration.

05 IP Routing Basics
Trending!
There are typically multiple IP subnets on a typical data communication network.
Layer 3 devices are required to exchange data between these IP subnets. These
devices have the routing capability and can forward data across subnets.
Routing is the basic element of data communication networks. It is the process of
selecting paths on a network along which packets are sent from a source to a
destination.
This note introduces the basic concepts of routing.

06 OSPF Basics
Trending!
Static routes are manually configured. If a network topology changes, static routes
have to be manually adjusted, which restricts the large-scale application of static
routes on the live network.
Dynamic routing protocols are widely used on live networks because of their high
flexibility, high reliability, and easy scalability. The Open Shortest Path First (OSPF)
protocol is a widely used dynamic routing protocol.
This course describes basic concepts,working mechanism, and basic configurations of OSPF.

07 Ethernet Switching Basics
Trending!
Data transmission on networks must comply with certain standards. Ethernet
protocols define how data frames are transmitted over an Ethernet network.
Understanding Ethernet protocols is the basis for fully understanding
communication at the data link layer. An Ethernet switch is the main device for
implementing data link layer communication. It is essential to understand how an
Ethernet switch works.
This note describes the concepts related to Ethernet protocols, MAC address
types, and working process and mechanism of Layer 2 switches.

08 VLAN Principles and Configuration
Trending!
Ethernet technology implements data communication over shared media based
on carrier sense multiple access with collision detection (CSMA/CD). If there are a
large number of PCs on the Ethernet, security risks and broadcast storms may
occur, deteriorating network performance and even causing network breakdowns.
The virtual local area network (VLAN) technology is therefore introduced to solve
the preceding problem.
This note describes basic VLAN principles, working principles of different Layer 2
interfaces, VLAN applications, data forwarding principles, and basic VLAN
configuration methods.

ENGINEERING MATHEMATICS
This textbook contains over 1000 worked problems, followed by some 1750 further problems (all with answers). The further problems are contained within some 220 Exercises; each Exercise follows on directly from the relevant section of work, every two or three pages. In addition, the text contains 238 multiple choice questions. Where at all possible, the problems mirror practical situations found in engineering and science. 500 line diagrams enhance the understanding of the theory.
At regular intervals throughout the text are some 18 Revision tests to check understanding. For example, Revision test 1 covers material contained in Chapters
1 to 4, Revision test 2 covers the material in Chapters 5 to 8, and so on. These Revision Tests do not have answers given since it is envisaged that lecturers could
set the tests for students to attempt as part of their course structure. Lecturers’ may obtain a complimentary set of solutions of the Revision Tests in an Instructor’s
Manual available from the publishers via the internet –see below. A list of Essential Formulae is included in the Instructor’s Manual for convenience of reference.
Learning by Example is at the heart of Engineering Mathematics 5th Edition.

Definition of the term “Law”
There is generally no acceptable definition of the word law. Different schools of Law define it differently. Some important definitions of law include: -
1. Woodrow Wilson, has defined law in the words “That portion of the established thought and habit
which has gained distinct and formal recognition in the shape of uniform laws, backed by authority and power of government”
2. According to Holland, “A law is a general rule of external human action enforced by sovereign political authority”
3. In the words of Salmond, “Law is a body of principles recognized and applied by the state in the administration of justice”.
4. Law may also be defined as” a rule of human conduct, imposed upon and enforced among the members of a given state”.
From the above definitions, we may conclude that law refers to “a set of rules or principles that govern the conduct of affairs in a given community at a given time, whereby machinery is provided for an aggrieved party to enforce his right in case any of these rules or principle is broken.

AECO 141: Principles of Agricultural Economics
Economics is popularly known as the “Queen of Social Sciences”. It studies economic activities of a man living in a society. Economic activities are those activities, which are concerned with the efficient use of scarce means that can satisfy the wants of man. After the basic needs viz., food, shelter and clothing have been satisfied, the priorities shift towards other wants.
