Getting Powershell Output to a File

Hello Experts,

I have a Powershell script that displays the output I want on the screen, but I'm not sure how to send it to a text or csv file as well.  I'm sure it is an easy thing to do, I'm just drawing a blank.  Here is my code:

$DaysInactive = 90
$Time = (Get-Date).Adddays(-($DaysInactive))
$DeadComputers = Get-ADComputer -Filter {LastLogonTimeStamp -lt $time} -Properties LastLogonTimeStamp | select name
foreach ($i in $DeadComputers)
{
if (Test-Connection -ComputerName $i.name -BufferSize 16 -Count 1 -Quiet) {Write-Host $i.name is online}
else {Write-Host $i.name is offline}
}

Thanks in advanced for your help.
