Study Notes
CCNA Overview
The Cisco Certified Network Associate (CCNA) is an entry-level IT certification provided by Cisco Systems. It validates individuals' skills and knowledge in installing, configuring, operating, and troubleshooting medium-sized networks. The CCNA certification focuses on three main areas: TCP/IP, routing and switching, and networking fundamentals. Additionally, the exam covers wireless networking concepts and technologies.
TCP/IP
TCP/IP stands for Transmission Control Protocol/Internet Protocol. It's a suite of communication protocols used to interconnect network devices on the internet and private networks. The primary responsibility of TCP/IP is providing reliable, ordered, and error-checked delivery of data between applications running on different hosts.
Routing and Switching
Routing refers to the process of choosing the best path between Source and Destination for the communication to take place. It is used in networks to connect multiple subnets and devices. There are two types of routing:
- Static Routing: This type of routing does not change the routing table unless the administrator makes changes.
- Dynamic Routing: This type of routing modifies the routing table automatically based on network conditions or changes.
Switching is the process of directing data packets to the correct destination. It is used in local area networks (LANs) to segment and control the flow of data.
Networking Fundamentals
The networking fundamentals of the CCNA certification cover the concepts that every network administrator should know. These concepts include:
- Subnetting: This is the process of dividing a network into smaller segments called subnets.
- OSI Model: A framework that describes how different network protocols interact and work together.
- IP Addressing: This involves understanding the different types of IP addresses (IPv4 and IPv6) and how they are used to uniquely identify devices on a network.
Wireless Networking
Wireless networking refers to the use of wireless technology to connect devices to a network. The CCNA exam covers wireless networking concepts and technologies. This includes:
- Wi-Fi: A popular wireless networking technology that uses radio waves to connect devices to a network.
- Wireless LAN (WLAN): A type of network that uses wireless technology to connect devices within a limited area.
- Wireless Security: The process of protecting wireless networks from unauthorized access and data theft.
In conclusion, the CCNA certification is an entry-level IT certification that validates an individual's skills and knowledge in installing, configuring, operating, and troubleshooting medium-sized networks. The exam focuses on TCP/IP, routing and switching, networking fundamentals, and wireless networking concepts and technologies.
