Network categories Various types of personal networks are known according to their specific dimension that involves machines installed and utilized, bandwidth, and coverage. Networks that are private are usually those networks that belong to a group of companies. These networks are categorized into three, namely: Wide Area NetworkMetropolitan Area NetworkLocal Area NetworkOther network categoriesThere are… Continue reading Network Types

Security The resources of network control access are the security management’s goal based on guidelines locally so that the unintentional or intentional sabotaging of the network will not push through and without the right authorization the access on sensitive data is not possible. Access refusal for those who entered access codes that are not correct… Continue reading Basics of Managing Networks for Security, Fault, and Accounting

Between devices of two networks within a network shared is where you can create a logical circuit called a virtual circuit which is classified into two categories, permanent and switched. Data transfer is one mode composing a virtual circuit that is established permanently and this is used in constant transfer of data between devices. The… Continue reading About Wide Area Network

For selecting the best route, software for switching is the one used wherein its information comes from tables for routing. We will focus our discussion on how the tables for routing is created, the particular information nature they have, and the use of algorithms for routing to know if a route is preferred over another.… Continue reading CCNA Metrics of Routing

From the link layer comes bridging and switching controlling the flow of data, error transmission handling, opposing logical in favor of addressing physicality, and physical medium access management. The algorithms of accessing the media, handling error, control of the flow, and addressing is primarily the focus of protocols with multiple link layers as these functions… Continue reading Bridges and Switches

When two or more devices of network have to send data at the same time, contention of media is present. Some method type must be used for letting one device access at a time for the network media because simultaneous network communication on various devices is not possible; and it is done by passing the… Continue reading CCNA Methods of Accessing the Media of Local Area Network

Internetworking Technologies History Based on the information gathered, attached terminals and mainframes used made up time-sharing networks which are said to be as the first networks. Both the architecture of Digital network and Systems Network Architecture (SNA) of International Business Machines (IBM) had implemented these network facilities. With the revolution of personal computers, the LANs… Continue reading History, Basics, and Challenges of Internetworking Technologies for CCNA
