CCNA: Learn the Fundamentals of Networking

What is CCNA?

CCNA certification is a popular network certification offered by Cisco Systems. This certification is available to all engineers, including network administrators and engineers. You should familiarize yourself with various networking concepts, such as OSI model and IP address.

Since 1998, it is believed that more than 1,000,000 CCNA certifications have been issued. CCNA stands for “Cisco Certified Network Associate”. The CCNA Course in Pune includes a variety of networking concepts, as well as CCNA basics. The CCNA course in Pune allows candidates to learn CCNA basic and prepares them for the latest technology in network technology.

CCNA certification covers a number of topics, including:

* OSI models

* IP addresses


ACL and Network Security Management

Routing protocols: EIGRP, OSPF, and RIP

* Routing IP

* Network Device Security



Why do you need a CCNA certification?

This certificate certifies the professional’s abilities to operate, configure and troubleshoot medium-level switched networks or routes. The certificate covers also the verification and implementation of connections made by remote sites using WAN.

The course will teach candidates how to create a point-to-point network

This course will teach you how to determine a network’s topology to meet the user’s requirements.

This book describes how to connect networks using routing protocols.

This article will explain how to create network address

This article will explain how to connect to remote networks.

* The certificate holder can install, configure and operate LAN and Wide Area Network Services for Small Networks

* CCNA certification is a pre-requisite for other Cisco certifications such as CCNA Security, CCNA Wireless (CCNA Wireless), CCNA Voice, etc.

The study material is simple to understand and follow.


Types of CCNA certification

To secure CCNA. Cisco offers five certification levels for networks: Entry, Associate, Professional Expert Architect. Cisco Certified Network Associate (CCNA) is a brand new certification program covering a broad range of IT basics.

CCNA’s certification program has been expanded to include a new course.

* CCNA Cloud

* CCNA Collaboration

* CCNA Routing & Switching

* CCNA Security

* CCNA service provider

* CCNA DataCenter

* CCNA Industrial

* CCNA Voice

* CCNA Wireless


What is the CCNA Course?

The CCNA networking course covers the basics of IPv4/IPv6 network configuration, installation, and operation. The CCNA Classes in Pune also includes network access, IP connectivity, and IP services as well as automation, programmability, and network security.

CCNA has changed a few things.

Understanding IPv6

CCNP Level subjects as HSRP DTP EtherChannel

Troubleshooting advanced Techniques

Supernetting and subnetting in network design


Criteria for certification

Certification does not require a degree. Some employers prefer certification. You should be familiar with the basics of CCNA.

Internet Local Area Networks

Local area networks are computer networks that connect computers within a certain area. For example, an office, a residence, a lab, etc. This network includes WLANs (wireless networks), LANs (local area networks), SANs (separate area networks), etc.

The most common are LAN, WLAN, and WAN. This guide will show you how to create local area networks by using network systems.


Understanding the Need for Networking

What is a Network?

A network is an arrangement of computers or devices which share resources such as printers or CDs. They can exchange files and communicate electronically.

Computers in a network may be connected by telephone lines, satellites or cables.

Two of the most common are:

Local Area Networks (LAN)

Wide Area Network (WAN)


Learn the difference between LAN & WAN

Layer 3 is the OSI reference layer that deals with networking. This layer is responsible for forwarding packets, routing through intermediate routers, and recognizing and forwarding local host domain messages.

Connecting computers and peripherals requires two pieces of equipment. Switches and routing are included. If two computers or other devices are connected via the same link, there is no need for a network layer.


Networking Internetworking Devices

To connect the internet, you will need a variety of internetworking devices. Some of the devices most commonly used to create internet are.

NIC is the acronym for Network Interface Card. These printed circuit board are installed in workstations. This is the physical connection between the network cable, and the workstation. NICs are devices that operate on the data-link layer even though they’re at the physical layer. NICs transfer data between workstations, networks and other devices. The NIC also controls the data transmission on the wire

Hubs: A hub is a network component that can extend the cable system. This is done by amplifying the signal and retransmitting it. They are basically multiport repeaters, and they don’t really care about the data. The hub connects to all workstations and then sends a transmission out for each workstation connected.


Bridges: As networks grow, they can be difficult to manage. To manage these networks, they are divided into smaller LANS. These smaller LANs are connected by bridges. It reduces network traffic and monitors packets that move between segments. It tracks the MAC address that is associated with each port.

As an alternative to bridges, switches can be used. Switches are more and more popular for connecting networks because they are smarter and faster than bridges. It can send information to specific workstations. Switches enable each workstation to transmit information independently from other workstations. It is similar to the modern telephone line, where several private conversations can be held simultaneously.

Routers: The purpose of a router is to transmit data as efficiently as possible to the destination device. They communicate using IP addresses, not MACs. Routers connect networks like the Internet Protocol network. Routers can link different networks such as Ethernet FDDI, Token Ring and others.

Routers are a hybrid of routers and bridges. Brouters are filters that let some data into the local network, while sending other data to another network. Modems convert digital signals from a computer into analog signals. They are transmitted over telephone lines.
