Slide 2 Cache and Error Chec&in1.4.4 Identif the na'es, purposes, and characteristics of (%A and (*A

Cac"e9 S(*A is used as cache 'e'or to store the 'ost fre;uentl useddata. S(*A provides the processor with faster access to the data thanretrievin it fro' the slower /(*A, or 'ain 'e'or. The three tpes of cache'e'or are! "1 cache is internal cache and is interated into the CP. "2 cache is e-ternal cache and was oriinall 'ounted on the 'other#oard

near the CP. "2 cache is now interated into the CP. "+ cache is used on so'e hih9end wor&stations and server CPs.Error C"ecking < Ae'or errors occur when the data is not stored correctl inthe (*A chips. The co'puter uses different 'ethods to detect and correctdata errors in 'e'or. Three different 'ethods of 'e'or error chec&in are! Bonparit 'e'or does not chec& for errors in 'e'or. Parit 'e'or contains eiht #its for data and one #it for error chec&in.

The error9chec&in #it is called the parit #it. Error Correction Code 8ECC< 'e'or can detect 'ultiple #it errors in

'e'or and correct sinle #it errors in 'e'or.
