This diagram shows an Enterprise Network Topology—basically how different networking devices are connected in an organization to provide internet, communication, and wireless access across floors.
Let me break it down in a simple way 👇
🔷 Core Devices (Main Backbone)
1. Cisco Router
Acts as the gateway to the internet 🌐
Connects your internal network to external networks
Handles routing between different networks
2. Cisco Switch-1 (Access Switch)
This is the central connection point for most devices
Connects:
Access Points (APs)
DHCP Server
Other wired devices
Works at Layer 2 (Switching)
3. Cisco Switch-2 (Distribution/Core Switch)
Connected to the router and KVM server
Handles higher-level traffic management
Acts as a bridge between core network and servers
4. KVM Server
A virtualization server 🖥️
Runs multiple virtual machines (servers) on one physical machine
Used for hosting services, applications, etc.
5. DHCP Server
Automatically assigns IP addresses to devices 📡
Without it, devices would need manual IP configuration
📶 Wireless Network (Access Points)
AP-1 & AP-2 (Floor 1)
Provide WiFi coverage on Floor 1
Connected to Switch-1
Serve multiple wireless users (laptops, phones)
AP-3 (Floor 2)
Provides WiFi on Floor 2
Also connected to Switch-1
Extends network coverage across floors
🔌 How Everything Connects
Router → Switch-1 → All devices (APs, DHCP, etc.)
Switch-2 → Connected to Router & KVM Server
APs → Connected to Switch-1 → Provide WiFi to users
DHCP Server → Assigns IPs to all connected devices
🧠 Overall Structure
This is a Hierarchical Network Design:
Core Layer → Router + Switch-2
Distribution Layer → Switch-1
Access Layer → APs & end devices
✅ What This Network Achieves
Centralized control 🧠
Scalable (easy to add more APs or devices)
Multi-floor WiFi coverage 📶
Efficient traffic handling

Definition of memory ✅
A memory is just like a human brain it is used to store data and instruction Computer memory is the storage space in the computer where data is to be processed and instruction required for processing our Store.
