that all Numberss have a para is normally used in informations

communications to guarantee the cogency of informations. This is

called para checking.

3 ) See page 186 of text for added infomation on Parity and ECC.

5 ) Interpret the two Advertisement # 3 memory ads on the affiliated page.

see page 228 of text.

1 ) 1 & # 215 ; 36 70/60 ( 4mb )

1 ten 36 = 1 ten ( 36/8 ) = 1 ten 4 = 4 megbyte ( 4mb memory )

Type of memory is Fast-Page Parity 70 N, 72 pin

See affiliated catalog transcript of fast page 30 pin SIMM

2 ) 8 & # 215 ; 72-100 ECC ( 64mb )

64 megbyte memory utilizing ECC ( Error rectifying codifications )

velocity is 100 megahertz.

Type of memory is PC100 ECC SDRAM at 100 megahertzs velocity.

See affiliated web page print out on PC-100 SDRAM layout.
