I would like to know about some commonly used download managers

A download manager is an application used to download and organise

the downloaded files from internet. It helps to accelarate the 

download speed and we can also download multiple files using a

download manager.You can download a internet manager on both the

windows and linux platforms. As all the softwares these are also 

affected by malwares but just try IDM, it's the best download manager

to go with downloads and some other prominent one's are–
