Overview
Welcome to the Basic Networking Concepts Lab. In this lab, you will receive the instructions and devices needed to develop your hands-on skills.
Learning Outcomes:
In this lab, you will learn to:
Use network utilities and protocols from the TCP/IP suite.
Use ping and arp to verify network layer connectivity.
Using basic network services with browsers, email, and FTP.
Key terms and descriptions
Network Communication
The exchange of data between computers or devices using wired or wireless connections
IP Address
A unique numerical identifier assigned to each device on a network (e.g., 192.168.1.1)
MAC Address
A hardware-based identifier (Media Access Control) embedded in network interface cards, used to uniquely identify a device on a local network
Port
A logical channel identified by a number used to differentiate multiple services or applications running on a single device
Secure Web Browsing
The use of encrypted protocols (such as HTTPS) to protect data exchanged between a web browser and a web server
File Transfer
The process of sending or receiving files between devices on a network using protocols like FTP, SFTP, or SMB
Email
A digital message system that uses standard protocols (SMTP, IMAP, POP3) to send and receive electronic messages across networks
Modem
A device that converts digital signals to analog for transmission over telephone lines and vice versa
Router
A device that connects multiple networks and directs data packets between them, typically between a local network and the Internet
Switch
A network device that connects devices within a LAN and uses MAC addresses to forward data to the correct destination
Access Point
A device that provides wireless access to a wired network, enabling Wi-Fi connectivity for wireless devices
Firewall
A security system (hardware or software) that monitors and controls incoming and outgoing network traffic based on predetermined security rules
Client/Server Model
A network architecture where a central server provides resources or services, and clients request access to them
Peer-to-Peer Model
A decentralized network model in which devices (peers) share resources directly without needing a central server
Local Area Network (LAN)
A network covering a small area like a home, school, or office building
Wide Area Network (WAN)
A network that spans a large geographic area, such as the internet, and connects multiple LANs
