This presentation is about the types of computer networks. I have explained each computer network discussed in the presentation with the help of using different sources.
Cloud computing is used to define a new class of computing that is based on the network technology. Cloud computing takes place over the internet. It comprises of a collection of integrated and networked hardware, software and internet infrastructures. These infrastructures are used to provide various services to the users. Distributed computing comprises of multiple software components that belong to multiple computers. The system works or runs as a single system. Cloud computing can be referred to as a form that originated from distributed computing and virtualization.

# 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

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.
2. History
• A computer network, or simply a network, is a
collection of computers and other hardware
components interconnected by
communication channels that allow sharing of
resources and information. Today, computer
networks are the core of modern
communication.
4. Network topology
• The physical layout of a network is usually less
important than the topology that connects
network nodes. Most diagrams that describe a
physical network are therefore topological,
rather than geographic. The symbols on these
diagrams usually denote network links and
network nodes.
5. Organizational scope
• Networks are typically managed by the
organizations that own them. Private
enterprise networks may use a combination of
intranets and extranets. They may also
provide network access to the internet, which
has no single owner and permits virtually
unlimited global connectivity.
6. Views of networks
• Users and network administrators typically
have different views of their networks. Users
can share printers and some servers from a
workgroup, which usually means they are in
the same geographic location and are on the
same LAN, whereas a Network Administrator
is responsible to keep that network up and
running.
7. Security
Network security consists of provisions
and policies adopted by the network
administrator to prevent and
monitor unauthorized access, misuse,
modification, or denial of the computer
network and its network-accessible resources.
8. Network resilience
Network resilience is "the ability to provide and
maintain an acceptable level of service in the
face of faults and challenges to normal
operation.
9. Routing
Routing is the process of selecting network
paths to carry network traffic. Routing is
performed for many kinds of networks,
includingcircuit switching networks and packet
switched networks.
10. Enterprise private network
• An enterprise private network is a network
that a single organization builds to
interconnect its office locations (e.g.,
production sites, head offices, remote offices,
shops) so they can share computer resources.
