    where() query,It iterates through each and every item and add it to IEnumerable.

    for example,

    "foreach (var item in myList)

    {
    if(//<condition>)
    {
    //add it to list/enumerable
    }
    //continue through entire list
    }"


    FirstOrDefault(<condition>) query, It starts iterating through the collection and breaks the loop as soon as it gets the item matching the <condition> and returns single element and if item is not available in list it will return "null".

    for example,

    "foreach (var item in myList)
    {
    if(//<condition>)
    {
    //return item
    break;
    }
    }"
