OSI Model: Understanding the Open Systems Interconnection (OSI) model and its seven layers, including Application layer, Presentation layer, Session layer, Transport layer, Network layer, Data link layer, and Physical layer.
Network Devices: Understanding the types of network devices, including routers, switches, hubs, bridges, modems, and firewalls; their roles, and how they interact with each other.
IP Addressing: Understanding the concept of IP addressing, IPv4 vs IPv6, subnetting, and how to assign IP addresses to devices.
Network Security: Understanding the importance of network security, types of attacks, security protocols, security topologies, and strategies for securing a network.
Network Management: Understanding network management concepts, including how to monitor network performance, troubleshoot network issues, and manage network resources.
Wireless Networking: Understanding wireless communication concepts, including the Wi-Fi standard, wireless security, and wireless network configuration.
Virtualization: Introduction to virtualization and virtual networks, including virtual machines, virtual switches, and virtual routers.
Cloud Computing: Understanding cloud computing concepts, including cloud networking, cloud security, cloud storage, and cloud architecture.
Routing and Switching: Understanding routing and switching concepts, including dynamic routing vs static routing, routing protocols, and how switches connect devices to a network.
Quality of Service (QoS): Understanding QoS concepts, including why QoS is important, how QoS works, and how to configure QoS on a network.
VoIP: Understanding Voice over Internet Protocol (VoIP) and how it works, including protocols involved, codecs, and how to configure VoIP on a network.
Network Design: Understanding network design principles, including the physical and logical design of a network, network planning, and network architectures.
Network Troubleshooting: Understanding how to troubleshoot network issues, including identifying common network problems, using network troubleshooting tools, and fixing network issues.
Network Performance Optimization: Understanding how to optimize network performance, including configuring network devices for maximum performance, and using monitoring tools to identify and resolve network performance issues.
Network Programming: Introduction to network programming concepts, including socket programming, client-server architecture, and network communication protocols like HTTP, FTP, and SMTP.
Network Administration: Introduction to network administration concepts, including network monitoring and management tools, network security, and network auditing.
Network Applications: Understanding how network technologies and protocols are used in different applications, such as email, file transfer, web browsing, and video conferencing.
LAN (Local Area Network): A network of computers and devices within a specific geographic area, such as a single building or campus.
WAN (Wide Area Network): A network that spans a large geographic area, such as multiple buildings, cities, or even countries.
MAN (Metropolitan Area Network): A network that covers a geographic area larger than a LAN but smaller than a WAN, such as a city or a region.
WLAN (Wireless Local Area Network): A LAN that uses wireless networking technologies such as Wi-Fi to connect devices without the need for cables.
PAN (Personal Area Network): A network that connects personal devices, such as smartphones, tablets, and computers, over a short distance.
SAN (Storage Area Network): A network that provides high-speed access to shared storage devices, such as disk arrays or tape libraries.
VPN (Virtual Private Network): A private network that uses a public network, such as the internet, to connect geographically dispersed users or organizations.
CAN (Campus Area Network): A network that connects multiple LANs within a university or corporate campus.
DAN (Desk Area Network): A network that connects devices within a specific workspace, such as a desk or cubicle.
GAN (Global Area Network): A network that connects geographically dispersed LANs and WANs into a single network, typically using satellite or wireless technologies.
"Computers use common communication protocols over digital interconnections to communicate with each other."
"These interconnections are made up of telecommunication network technologies based on physically wired, optical, and wireless radio-frequency methods."
"The nodes of a computer network can include personal computers, servers, networking hardware, or other specialized or general-purpose hosts."
"They are identified by network addresses and may have hostnames."
"Hostnames serve as memorable labels for the nodes and are rarely changed after initial assignment."
"Network addresses serve for locating and identifying the nodes by communication protocols such as the Internet Protocol."
"Computer networks may be classified by many criteria, including the transmission medium used to carry signals, bandwidth, communications protocols to organize network traffic, the network size, the topology, traffic control mechanisms, and organizational intent."
"Computer networks support many applications and services, such as access to the World Wide Web, digital video and audio, shared use of application and storage servers, printers and fax machines, and use of email and instant messaging applications."
