– A switch is a hardware networking device that connects multiple nodes, receives information from all nodes and sends it only to the selected node.– A switch has multiple ports to connect with multiple nodes.– A switch is called intelligent hub as it analyses and receives data and send it to intended node. A switch […]

– A hub is hardware networking device that connects multiple nodes in a network and send and receive data from all the connected nodes.– A hub contains multiple ports that are used to connect multiple nodes.– A hub is best suitable device for creating small home network (LAN). – A hub transmits data in half

A computer network is a system in which two or more autonomous computers are connected to each other. These computers can share information and other resources. A computer network may also include peripherals such as printers, scanners, webcams, speakers, headphones, microphones etc. you can use these devices to send and receive data and perform tasks,

Push- new data element is added at the top of stackWe can use <stack>.append(<item>) Pop- data element is removed from the top of the stackWe can use <stack>.pop()

Input/output restricted queues are two variations of deque. Input restricted deque- it allows insertion at only one end but allows deletion at both end of the list Output restricted deque – it allows deletions at only one end of the list but allows insertions at both ends of the list

Queue Deque Data elements can be either inserted or deleted at one end Data elements can be inserted or deleted from both the ends We can not reuse memory space once element is deleted from it We can reuse memory space of deleted element for new element to be inserted

Linear Queue Circular Queue Data elements are stored in linear patter Data elements are stored in circular pattern where rear end is connected with front end It occupies more memory space It occupies less memory space Insertion and deletion of elements are possible from rear and front end only Insertion and deletion of element are
