How to replace a string in a SQL Server Table Column

Question

I have a table  SQL Sever  which references paths  UNC or otherwise   but now the path is going to change    In the path column  I have many records and I need to change just a portion of the path  but not the entire path  And I need to change the same string to the new one  in every record   How can I do this with a simple update

all answers are great but I just want to give you a good example

select replace('this value from table', 'table',  'table but updated')

this SQL statement will replace the existence of the word "table" (second parameter) inside the given statement(first parameter) with the third parameter

the initial value is this value from table but after executing replace function it will be this value from table but updated

and here is a real example

UPDATE publication
SET doi = replace(doi, '10.7440/perifrasis', '10.25025/perifrasis')
WHERE doi like '10.7440/perifrasis%'

for example if we have this value

10.7440/perifrasis.2010.1.issue-1

it will become

10.25025/perifrasis.2010.1.issue-1

hope this gives you better visualization
