Chapter 1, Problem 12SA
Why does byte code make Java a portable language?
Expert Solution & Answer
Explanation of Solution
Byte code:
Java program is the high-level language. So, java compiler is used to compile the java program (high-level language) into java bytecode (standard machine code).
- Bytecode program runs on any machine that has a JVM (Java Virtual Machine) interpreter.
- The JVM (Java Virtual Machine) interpreter is designed to execute the bytecode program produced by the compiler.
- The interpreter takes the bytecode to convert the machine code and executes it.
- Unlike machine language code, byte code is same for all the computers which have JVM in it. Hence, Java program is easily portable.

Simulate on a vertical time axis (with events labeled with the senders names A-D) the contention period of FOUR equally distanced Ethernet stations that all attempt to transmit at T=0 a minimally sized frame, in the style of the binary Exponential Backoff Algorithm. Assume that time is measured in slot times, and that exactly one slot time is needed to detect a collision (so that if two stations transmit at T=1 and collide, and one of them chooses a backoff time k=0, then that station will transmit again at T=2).
Use as coin flip (source of randomness) an ID written in binary.
use the bits in order from the least significant to the most significant. If for a given coin throw you need k bits, use the least significant ID bit extracted in the corresponding group of bits, as the least significant bit of the coin thrown.
Start be writing the ID, which is 904012207

- Big State University The Big State University course catalog reads as follows: "To enroll in MIS 260, which is an advanced course, a student must complete two prerequisites: MIS 120 and MIS 222. A student who completes either one of these prerequisites and obtains the instructor's permission, however, will be allowed to take MIS 260." Tasks 1. Create a decision table that describes the Big State University course catalog regarding eligibility for MIS 260. Show all possible rules. 2. Simplify the table you just created. Describe the results. 3. Draw a simplified decision tree to represent the Big State University catalog. Describe the results. 4.
