The SECD machine is a prototype abstract machine for higher-order functional languages using the by-value strategy to evaluate lambda “calculus” expressions. It determines how to compute the function expression before evaluating the function expression.

2a) Briefly explain the acronym SECD.

Expert Solution

Answer to 2a

SECD is virtual and abstract machine which is used for high order functional languages to evaluate lamda calculus expressions. The full form of acronym SECD is Stack, Environment ,Control ,Dump machine.

SECD machine contains the registers "stack environment control dump" to help in compilation of functional languages. SECD machines uses the stack based technology which takes an argument from the stack with certain rules and performs the computing of lambda " calculus" expressions.The SECD machine uses four stacks as registers which are as follows-

Stack - It is used to store the partial results of evaluation of lambda expressions and holds the final results of machines execution.
Environment - It has series of pairs that give values to free variables in the expression where the first element of pair is identifier and second elements is it's associated value.
Control - This stack stores the lambda calculus expression which is being evaluated.
Dump - The Dump is used to store the copies of the four stacks.

1) A machine contains 5 components that all need to be functional in order for the equipment to operate. The reliability of the components is .99, .98, .99, .999, and .96, what is the resulting system reliability? 2) If the second and fourth components had redundant components with the same reliabilities what would be the system reliability?

A machine purchased three years ago for $85,000 has a current book value using straight-line depreciation of $55,000; its operating expenses are $14,000 per year. The current disposal value of the old machine is $30,000; if it is kept 5 (five) more years, its residual value would be $5,000. A replacement machine would cost $100,000, have a useful life of 5 (five) years, and would require $4,000 per year in operating expenses. It has an expected salvage value of $10,000...
