2. Network Architecture Overview
 A computer network is a collection of devices that are interconnected to
communicate and share resources. The architecture of a network refers to
the design and organization of its components and how they interact with
each other.
 There are various types of network architectures, including client-server,
peer-to-peer, and hybrid. Each architecture has its own advantages and
disadvantages, and the choice of architecture depends on the specific
needs and requirements of the network.
 In general, a network architecture consists of hardware components such
as routers, switches, and servers, as well as software components such as
protocols and applications. These components work together to ensure
efficient and reliable communication and resource sharing between
devices on the network.

3. Network Security Measures
 Firewalls
 We use firewalls to protect our network from unauthorized access and malicious attacks.

 Encryption
 We use encryption to secure our data transmissions and protect sensitive information.

 Access Control
 We implement access control measures to ensure that only authorized users can access
our network resources.

5. Bandwidth Management
 Effective bandwidth management is
essential for optimizing network
performance. This involves prioritizing
traffic and allocating bandwidth to
critical applications and services.
Network administrators can use
Quality of Service (QoS) protocols to
ensure that high-priority traffic is
given priority over low-priority traffic.
Additionally, bandwidth throttling can
be used to limit the amount of
bandwidth allocated to non-critical
applications.
Load Balancing
 Load balancing involves distributing
network traffic across multiple servers
or network devices to prevent any
single device from becoming
overloaded. This helps to improve
network performance by ensuring
that resources are utilized efficiently.
Load balancing can be implemented
using hardware or software solutions,
and can be configured to distribute
traffic based on various criteria such
as server availability, traffic type, and
geographic location.

7. Network Monitoring and Maintenance
Network Monitoring
 Network monitoring involves the
continuous observation and analysis
of network traffic to identify issues
and ensure optimal performance. This
can be done through various tools
and techniques, such as packet
sniffers, network analyzers, and flow-
based monitoring.
Network Maintenance
 Network maintenance involves the
regular upkeep and updates of
network hardware and software
components to ensure optimal
performance and security. This can
include tasks such as software patches
and updates, firmware upgrades, and
hardware replacements or repairs.
