36. Figure below shows TCP communication between Alice and Bob. Bob Alice Seq = 1022, 28-bytes data Seg

Computer Architecture Given the below IEEE single precision FP format: 1-bit Sign , 8-bit Biased Exponent , 23-bit Mantissa , Bias = 127 Convert (9.625)10 to IEEE 32-bit floating-point format.

In relation to a number, what does it mean when a bit is "activated"? What does the numerical representation of a bit that is not connected mean?

Express -1.5 in IEEE 32-bit floating-point format.

In the hamming code C (7, 4), three redundant bits are generated as follows:0 2 1 0 r = a ⊕ a ⊕ a1 3 2 1 r = a ⊕ a ⊕ a2 3 1 0 r = a ⊕ a ⊕ a

Bit length can be defined in terms of Bit duration explain?

Needham and Schroeder suggest the following variant of their protocol: 1. Alice → Bob : Alice 2. Bob→ Alice: {Alice rand3}kBob 3. Alice → Cathy : {Alice Bob rand₁|{Alice rand3}kBob} 4. Cathy → Alice: {Alice Bob rand₁|ksession|{Alice rand3|ksession}KBob}KAlice 5. Alice → Bob: {Alice rand3|ksession}kBob 6. Bob→ Alice: {rand2}ksession 7. Alice → Bob: {rand2-1}ksession Show that this protocol solves the problem of replay as a result of stolen session keys. Hint: Consider two cases, one in which the attacker does not send an initial message to Bob and one in which the attacker does.

Character P is encoded as 1010000 in a computer. Usually, a parity bit will be sent together with a character. What is the odd parity bit for character P?
