System = 256Byte = 8 bit
Cache = 64B , block size = 16 byte.
A) Direct Mapped Cache:
Block offset = log (Block size) = log 16 = 4bit
Total # of block inside cache = 4.
Therefore index offset = log 4 = 2bit.
Remaining is tag bits.
Therefore tag bits = 8-(4+2) = 8-6 = 2 bits
Tag Index offset Block offset
(2 bits) (2 bits) (4 bits)
Fully associative cache :
In fully associative cache, any of main memory block can be placed anywhere in cache. Therefore index offset =0 bits.
Therefore tag bits = 8-block offset bit= 8-4 =4bits
Tag Block offset
(4 bits) (4 bits)
Answer:
The five rules are described as follows:
Rule A permits the inbound Simple Mail Transfer Protocol (SMTP) connection.
Rule B permits the inbound Simple Mail Transfer Protocol (SMTP) connection.
Rule C permits the outbound Simple Mail Transfer Protocol (SMTP) connection.
Rule D permits the outbound Simple Mail Transfer Protocol (SMTP) connection.
Rule E does not perform any action. Thus it is when the action is denied.
Explanation:
Rule A allows information transfer of the incoming email from the external server to the internal remote server, thus this allows an inbound connection.
Rule B allows information transfer of the incoming email from the remote server to the external remote server, thus this allows an inbound connection.
Rule C allows information transfer of outgoing email from the external server to the internal remote server, thus this allows an outbound connection.
Rule D allows information transfer of the outgoing email from the remote server to the external remote server, thus this allows an outbound connection.
Rule E does not allow any action in either direction thus it is when action is denied.
