Build Your Skills And Your Career: Certify Yourself
The Cisco® CCNA™ certification lays the foundation for all other Cisco® certifications.
The Cisco® Certified Network Associate™ certification solidifies and markets your knowledge of installing, configuring, and operating routed LANs and WANs. Optimizing WAN traffic through Internet access solutions that reduce bandwidth, and reducing WAN costs using features such as access list filters are also professional tasks of a CCNA™.
A CCNA™ can do the following:
- Install and configure Cisco switches and routers in multiprotocol internetworks using LAN and WAN interfaces
- Provide Level 1 troubleshooting service
- Improve network performance and security
And, according to Cisco®, the CCDA™ certification indicates knowledge of network design for the Small Office, Home Office (SOHO) market and for medium-size organizations whose simple LAN, routed WAN, and switched LAN networks have fewer than 500 nodes.
A CCDA™
can do the following:
Determine
the customer's requirements for network performance, security, capacity,
and scalability
Design a network structure that meets these requirements
Articulate the benefits of the design to the customer's satisfaction
Develop and test a prototype network that validates the design—and
demonstrate that proof to the customer's satisfaction
Cisco® certifications enhance your career path by:
- Validating achievements, knowledge and hands-on skill base.
- Increasing professional credibility.
- Diversifying and heightening skills, ensuring the ability to tackle the newest, cutting-edge technologies.
Cisco® certifications also afford you special membership benefits:
- A certificate of accomplishment.
- A wallet card, logo and designation for your personal promotion to clients or potential employers.
- Access to the secure Cisco® on-line tracking system so you can download logos, and track your Cisco® certification progress throughout your career.

Network Interface
TCP is a reliable connection-oriented protocol that provides data
transfer, multiplexing, error recovery, flow control using
windowing, connection establishment, and termination.
A connection must be established and the two hosts must synchronize
each other’s initial sequence numbers before communication takes
place. This process is called a three-way handshake and is necessary
because sequence numbers are not tied to a global clock in the
network, and TCP might have a different mechanism for picking the
initial sequence number. To achieve reliability, TCP uses sequences,
ACKs, and flow control (windowing).
The TCP window size determines how much data the receiving station
will accept at tone time before an acknowledgement will be returned.
With a window size of 3, three segments will be sent, and one ACK
for all three frames will be sent back. If the segments are not
ACKed, no more data may be sent until they are. The starting ACK
numbers in TCP are stated during initialization.
A TCP socket consists of a layer 3 IP address, layer 4 protocol, and
port number. TCP accomplishes data transfer by establishing a
connection between sockets on each of the endpoint computers.
Applications use a TCP service by opening a socket and TCP manages
delivery of the data to the other socket. TCP uses the socket
connection between the two sockets to perform multiplexing, which is
a function used to decide the correct application for a packet based
on port number. Applications, such as FTP, open a socket using a
well-known port and listen for connection requests.
UDP (User Datagram Protocol) is unreliable, connection-less, and
used for broadcasting information. No error checking for segment
delivery is provided at this layer. UDP depends on upper-layer
protocols for reliable data transfer.
IP (Internet Protocol): The specifications for IP were established
by RFC in 1982. This structure provides for a 32-bit logical address
(network id, host id) for each host, router, and node interface. An
IP address is expressed as four decimal values in the range of
0-255, separated by periods, called dotted decimal notation. These
decimal values each represent 8 bits of the 32-bit address, known as
an octet. An example of this would be 192.168.100.20.
