What is the Keyboard that Provides Data Entry to the Computer?

The keyboard is a device that offers the keypad of various devices, machines, and instruments. In general, the keyboard allows control or command of the device in question. Currently, the term is closely related to the peripheral that allows data to be entered on a computer or another digital machine. When the user presses a … 

 

What is Software in Computer Systems?

Software (SW) is a set of instructions that a computer must follow, that is, it contains all the instructions on what to do and how to do it. The concept of software covers everything that is intact, such as programs and operating systems, that are abstract in the computer. This definition contradicts the physical components … 

 

What is Ethernet, Frequently Used in Computer Networks?

We often use the term Ethernet when the information transfer medium is done over wired computer networks, not over Wi-Fi. The Ethernet network is a network that meets the standards of both the physical (wired) environment and the way to communicate through it. The standard is determined by IEEE under the number 802.3. The parameters …

How to Configure EIGRP Routing on a Cisco Router using Cisco Packet Tracer

EIGRP operates as an advanced distance vector routing protocol that offers the best features of Cisco’s distance vector and link-state algorithms in TCP/IP and Open Systems Interconnection (OSI) networks. Cisco developed IGRP (Internal Gateway Routing Protocol) using distance vector-type routing technology. The purpose of this protocol is that each router knows only the address (next-hop … 

 

What is EIGRP Protocol (Enhanced Interior Gateway Routing)?

EIGRP (Enhanced Interior Gateway Routing Protocol) is an improved version of the original IGRP protocol developed by Cisco Systems. Cisco-specific EIGRP routing technology combines the advantages of link-state protocols with the advantages of distance vector protocols. EIGRP maintains the same distance vector algorithm and original IGRP matrix information; however, considerations regarding convergence time and expansion … 

 

How to Configure OSPF Routing on a Cisco Router using Cisco Packet Tracer

Packet Tracer is a program developed by Cisco to configure computer networks in a “virtual” way. In this way, you can design a TCP/IP network in a virtual environment with this software before making sure it will work in the real scenario. An OSPF network can be divided into smaller regions (areas). There is a … 

 

What is OSPF Protocol (Open Shortest Path First)?

OSPF (Open Shortest Path First) is an internal gateway hierarchical routing protocol or IGP (Internal Gateway Protocol) that uses the Dijkstra link-state algorithm (LSA – Link State Algorithm) to calculate the route. It uses “cost” as a metric measurement as possible, and additionally creates the same link-state database for all routers in the zone. OSPF …
