This document discusses different types of communication media, including guided and unguided media. Guided media, also called bounded media, directly links communication devices through cables or physical pathways like twisted pair wires, coaxial cables, and fiber optic cables. Unguided or wireless media transmits data through the air using antenna in either directional beams or omni-directionally. The document provides details on advantages and disadvantages of each type of guided media.

The increasing number of people who transfer data from one place to another daily demands that the telecom industries develop a sophisticated strategy to guaranty quality data transferred without compromise or interception. Some of these industries in a bid to meet up with this demand employ any means of data transfer possible to them. Internet connectivity requires physical transfer of data from one place to another. This can be achieved either through wire or wirelessly. Connection through wire could be by UTP, Coaxial or Fiber Optics. Experience showed that wired is more advantageous when considering bandwidth utilization, performance, reliability, resiliency and security, many people are toeing this way and fiber optics their major choice. Fiber optics can be bundled as cable and used for data transmission through which light propagates with little attenuation, which makes it advantageous for long distance communication. The massive choice of fiber optics of recent has increase the security challenges bedevilling it, as it is now the prime target of network attackers. This has increased its vulnerability. Fiber optic is experiencing some security issues like splicing, clamping, cutting and tapping in developing countries like Nigeria. The paper tries to evaluate the security challenges bedevilling the optic fiber

Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors.
Wireless communication is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal through wireless communication technologies and devices.
Features of Wireless Communication
The evolution of wireless technology has brought many advancements with its effective features.
The transmitted distance can be anywhere between a few meters (for example, a television's remote control) and thousands of kilometers (for example, radio communication).
Wireless communication can be used for cellular telephony, wireless access to the internet, wireless home networking, and so on.

# Internet Security: Safeguarding Your Digital World
In the contemporary digital age, the internet is a cornerstone of our daily lives. It connects us to vast amounts of information, provides platforms for communication, enables commerce, and offers endless entertainment. However, with these conveniences come significant security challenges. Internet security is essential to protect our digital identities, sensitive data, and overall online experience. This comprehensive guide explores the multifaceted world of internet security, providing insights into its importance, common threats, and effective strategies to safeguard your digital world.
## Understanding Internet Security
Internet security encompasses the measures and protocols used to protect information, devices, and networks from unauthorized access, attacks, and damage. It involves a wide range of practices designed to safeguard data confidentiality, integrity, and availability. Effective internet security is crucial for individuals, businesses, and governments alike, as cyber threats continue to evolve in complexity and scale.
### Key Components of Internet Security
1. **Confidentiality**: Ensuring that information is accessible only to those authorized to access it.
2. **Integrity**: Protecting information from being altered or tampered with by unauthorized parties.
3. **Availability**: Ensuring that authorized users have reliable access to information and resources when needed.
## Common Internet Security Threats
Cyber threats are numerous and constantly evolving. Understanding these threats is the first step in protecting against them. Some of the most common internet security threats include:
### Malware
Malware, or malicious software, is designed to harm, exploit, or otherwise compromise a device, network, or service. Common types of malware include:
- **Viruses**: Programs that attach themselves to legitimate software and replicate, spreading to other programs and files.
- **Worms**: Standalone malware that replicates itself to spread to other computers.
- **Trojan Horses**: Malicious software disguised as legitimate software.
- **Ransomware**: Malware that encrypts a user's files and demands a ransom for the decryption key.
- **Spyware**: Software that secretly monitors and collects user information.
### Phishing
Phishing is a social engineering attack that aims to steal sensitive information such as usernames, passwords, and credit card details. Attackers often masquerade as trusted entities in email or other communication channels, tricking victims into providing their information.
### Man-in-the-Middle (MitM) Attacks
MitM attacks occur when an attacker intercepts and potentially alters communication between two parties without their knowledge. This can lead to the unauthorized acquisition of sensitive information.
### Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) Attacks

3. What is Communication Media?
A path through which data is
transmitted from one place to
another is known as Communication
media.
The method or tools in which information can
be exchange and communication can be
facilitated.
Example telephone,e-mail,web-
site,messaging etc
4.
5. Guided Media
communication devices are directly linked with each
other via cables or physical media is called Guided
media.
guided media is also called Bounded media.
The examples of guided or bounded media are:
Twisted pair wire
Coaxial cable
Fiber optic cable
6. 1. Twisted pair cable: -
It consists of two identical 1 mm thick copper wires
insulated and twisted together. The twisted pair
cables are twisted in order to reduce crosstalk and
electromagnetic induction.
Advantages:
(i) It is easy to install and maintain.
(ii) It is very inexpensive
Disadvantages:
(i) It is incapable to carry a signal over long
distances without the use of repeaters.
(ii) Due to low bandwidth, these are unsuitable for
broadband applications.
7. 2. Co-axial Cables:
It consists of a solid wire core surrounded by one
or more foil or braided wire shields, each
separated from the other by some kind of plastic
insulator. It is mostly used in thecable wires.
Advantages:
(i) Data transmission rate is better than twisted
pair cables.
(ii) It provides a cheap means of transporting
multi-channel
television signals around metropolitan areas.
Disadvantages:
(i) Expensive than twisted pair cables.
(ii) Difficult to manage and reconfigure.
8. 3. Optical fiber: -
An optical fiber consists of thin glass fibers that
can carry information in the form of visible light.
Advantages:
(i) Transmit data over long distance with high
security.
(ii) Data transmission speed is high
(iii) Provide better noise immunity
(iv) Bandwidth is up to 10 Gbps.
Disadvantages:
(i) Expensive as compared to other guided media.
(ii) Need special care while installation?
9. Unguided media relates to data transmission
through the airand is commonly referred to as
wireless.
The transmission and reception of data is carried
out using antenna.
There are two main ways that antenna work:
Directional (in a beam)
Omni directional (all around)
