Duplex Settings

There are two types of duplex settings used for communications on an Ethernet network: half duplex and full duplex. The figure shows the two duplex settings available on modern network equipment. Half Duplex: Half-duplex communication relies on unidirectional data flow where sending and receiving data are not performed at the same time. This is similar to how walkie-talkies or two-way radios function in that only one person can...

key elements ethernet 802.3 networks

In this topic, you will learn about key components of the Ethernet standard that play a significant role in the design and implementation of switched networks. You will explore how Ethernet communications function and how switches play a role in the communication process. CSMA/CD Ethernet signals are transmitted to every host connected to the LAN using a special set of rules to determine which station can access the network....

LOGIC GATE

Computer system architecture is composed of a series of logic 1 (true) and 0 (false) combined with a number of logic gates are AND, OR, NOT, NOR, XOR, NAND.The computer program running on the basic structure of good reasoning from a solution to the problems with the help of the program component that is if-then, if - then-else and o...

Access Layer Switch Features

Now that you know which factors to consider when choosing a switch, let us examine which features are required at each layer in a hierarchical network. You will then be able to match the switch specification with its ability to function as an access, distribution, or core layer switch.Access layer switches facilitate the connection of end...

Switch Features

Switch Form FactorsWhat are the key features of switches that are used in hierarchical networks? When you look up the specifications for a switch, what do all of the acronyms and word phrases mean? What does "PoE" mean and what is "forwarding rate"? In this topic, you will learn about these features.When you are selecting a switch, you need...

Considerations for Hierarchical Network Switches

Traffic Flow AnalysisTo select the appropriate switch for a layer in a hierarchical network, you need to have specifications that detail the target traffic flows, user communities, data servers, and data storage servers.Companies need a network that can meet evolving requirements. A business may start with a few PCs interconnected so that they can share data. As the business adds more employees, devices, such as PCs, printers,...

what is converged network

Small and medium-sized businesses are embracing the idea of running voice and video services on their data networks. Let us look at how voice and video over IP (VoIP) affect a hierarchical network.Legacy EquipmentConvergence is the process of combining voice and video communications on a data network. Converged networks have existed for a while now, but were only feasible in large enterprise organizations because of the network...

Configuring STP

Task 1: Examine the STP Default StateStep 1. Examine link lights.When STP is fully converged, the following conditions exist:All PCs have green link lights on the switched ports.Access layer switches have one forwarding uplink (green) to a distribution layer switch and a blocking uplink (amber) to a core layer switch.Distribution layer switches...

Switched LAN Architecture

Access LayerThe access layer interfaces with end devices, such as PCs, printers, and IP phones, to provide access to the rest of the network. The access layer can include routers, switches, bridges, hubs, and wireless access points. The main purpose of the access layer is to provide a means of connecting devices to the network and controlling...

Grouping Basic Programming Language

If the source comes from the natural language is the language of construction will be similar to the real meaning.It will certainly make it easier for programmers to program, especially for those who have not experienced. Sometimes it can be ambiguous, because sometimes a lot of natural language that has many meanings. Example: SQL.If the source comes from the language of mathematics would be very logical, mathematical, and...

Flag Register

Carry flag is generally composed of nine pieces Flow Over Flag (OF): Value 1 if there is overflow (OV) and set to 0 (NV). Sign Flag (SF): Distinguishing numbers marked. Positive numbers (PL) or a negative number (NG).Zero Flag (ZF): Value 0, if the result is worth one operation.Carry Flag (CF): Value 1 in case (borrow) on the subtraction operation or (carry) on the addition operation.Parity Flag (PF): Value 1 if an evenDirection...
