Concept of the guidance is based on Cisco CCNA 640-802 exam topics or blue print of the exam. Please note, that I am not offering you cheat sheet CCNA 640-802, but once again I just want to share my knowledge in Cisco CCNA level, so it can be usefull in real world.CCNA Study Guidehttp://www.blogger.com/profile/03172299544243729755noreply@blogger.comBlogger10125tag:blogger.com,1999:blog-1239193331280426118.post-18897832040401362052010-08-23T08:00:00.000-07:002010-08-27T06:37:32.956-07:001.4 Common TCP and UDP Network Applications

Before you continue reding this topic, please make sure you already understand our previous topic about OSI and TCP/IP Model. In TCP/IP, a port is mecanism that allow a computer to have more than one session to communicate with other computer or other devices in internetwork. A port can identify a specific process to which a computer or other network message need to be forwarded when it arrives

This sample CCNA exam will review your knowledge about OSI and TCP/IP Model. Questions : You issue ping command and you get output shows “request times out”. Which OSI layer this problem reside ? Which layer of the OSI model is responsible for ensuring reliable end-to-end delivery of data? At which OSI layer is a logical path created between two host ? The acknowledgement of transmissions,

The Open Systems Interconnection model (OSI model) defined by Open Systems Interconnection, while the Transmission Control Protocol/Internet Protocol (TCP/IP) model was created by Departement of Defense (DoD). Lets take a look at OSI 7 layer model and comparison to TCP/IP model. Table 1 – OSI Model Summary Layer Function Description Sample Protocols/Technologies 7.

As mentioned in section 1.1, we already knows something about router, switch, and hub, also bridge as addition in internetwork. Figure below shows how network look with all of those internetwork devices in place. Please note that left and right part of this figure are not commonly use this day (we can say that bridge and hub are old technology). Typical network this day can be found in middle

Why would we need to limit bandwidth on cisco switch ? I never think why until my friend ask me how to do that couple of times (may 2 months ago). Here is a sample scenario and configuration on cisco switch to limit interface bandwidth. As you can see on figure 1, we need to connect Customer LAN in building A to LAN building B. We need to limit their bandwidth to for example 256Kb because

We have talked about collision domain in switch and hub. So, what is collision domain, broadcast domain and how to count them ? What is collision domain and broadcast domain ? Collision Domain is a group of Ethernet or Fast Ethernet devices in a CSMA/CD LAN that are connected and compete for access on the network. Only one device in the collision domain may transmit at any one time, and the

In this section we will discuss about difference between Switch and Hub (Switch vs Hub). Before Switch were introduced, Hub were standard device to interconnecting PC and/or another devices on Local Area Network (LAN). Hub work in layer 1 at OSI Model. The drawbacks with hubs : Hub is very simple device that accept a single data packet then sends it out to all the computers that are connected

Major network component : router, switch, hub, and bridge. A router is a device that interconnects two or more computer networks. Basicly, function of the router are to interconnecting networks by selecting best path (routing/path selection) for a packet to travel, and forward packet (packet switching) to outgoing interface using best path in routing table. Routing or selecting best path in a
