Impact of User Applications on the Network

Oracle11g SQL| Impact of User Applications on the Network The data traffic that is flowing in a network can be generated by end users or can be control traffic. Users generate traffic by using applications. Control traffic can be generated by intermediary devices or by activities related to operation, administration, and management of the network. Today, users utilize many applications. The traffic created by these applications differs in its characteristics.… Read More »Impact of User Applications on the Network

Interpreting a Network Diagram

Interpreting a Network Diagram Network diagrams are visual aids in understanding how a network is designed and how it operates. In essence, they are maps of the network. They illustrate physical and logical devices and their interconnections. Depending on the amount of information you wish to present, you can have multiple diagrams for a network. Most common diagrams are physical and logical diagrams. Other diagrams used in networking are sequence… Read More »Interpreting a Network Diagram

Physical vs. Logical Topologies

Each network has both a physical and a logical topology. The physical topology of a network refers to the physical layout of the devices and cabling. The term node is commonly used when discussing topology diagrams. For networking topology diagrams, a node is a device. Two networks might have the same physical topology, but distances between nodes, physical interconnections, transmission rates, or signal types may be different. A physical topology… Read More »Physical vs. Logical Topologies

Characteristics of a Network

Characteristics of a Network When you purchase a mobile phone or a PC, the specifications list tells you the important characteristics of the device, just as specific characteristics of a network help describe its performance and structure. When you understand what each characteristic of a network means, you can better understand how the network is designed, how it performs, and which aspects you may need to adjust to meet user… Read More »Characteristics of a Network

Components of a Network

Components of a Network A network can be as simple as two PCs that are connected by a wire or as complex as several thousand devices that are connected through different types of media. The elements that form a network can be roughly divided into 3 categories: devices, media, and services. Devices are interconnected by media. Media provides the channel over which the data travels from source to destination. Services… Read More »Components of a Network

What is Computer Network

What Is a Computer Network? The term network is used in many different arenas. Examples of networks are social networks, phone networks, television networks, neural networks, and, of course, computer networks. A network is a system of connected elements that operate together. A computer network connects personal computers (PCs), printers, servers, phones, cameras, and other types of devices. A computer network connects devices in a way allowing them to exchange… Read More »What is Computer Network
