A PERT network chart describes the duration of each project activity in terms of optimistic or best-case scenario (O), pessimistic (P), and expected or most likely (E or M).
What is a timeline?In Computer technology, a timeline is sometimes referred to as duration and it can be defined as a list of important events or activities that are arranged in a chronological sequence, which is the order in which they happened (occurred).
What is a PERT network?PERT network is an abbreviation for Program Evaluation and Review Technique and it can be defined as a network model that was designed and developed in the late 1950's for the Polaris project of the United State Navy, which had thousands of contractors.
Additionally, the Program Evaluation and Review Technique (PERT) network helps project manager to significantly reduce both the cost and amount of time (duration) that are required to successfully complete a project, as well as randomness in activity completion times.
In conclusion, the main purpose of determining the critical path on a Program Evaluation and Review Technique (PERT) network is to enable project managers in identifying the sequence of tasks that takes the longest time (duration) to complete, during the execution of a project.

What is the greatest magnitude negative number one can represent in
an 8-bit 2's complement code? Write your result in binary and
decimal.
In 2's complement notation, the range of numbers that can be represented with an n-bit system is from -2ⁿ⁻¹ to 2ⁿ⁻¹ - 1. In an 8-bit system.
This means that the maximum magnitude of a positive number that can be represented is 2⁷ = 128 and the minimum magnitude of a negative number that can be represented is -2⁷ = -128. This leaves one bit for representing the sign of the number.
The greatest magnitude negative number that can be represented in an 8-bit 2's complement code would have a binary representation of 10000000. To find the decimal equivalent, we can calculate the value of the bits using their corresponding powers of 2 and add them together:1 * -128 + 0 * 64 + 0 * 32 + 0 * 16 + 0 * 8 + 0 * 4 + 0 * 2 + 0 * 1= -128Therefore, the greatest magnitude negative number that can be represented in an 8-bit 2's complement code is -128, with a binary representation of 10000000.

. interrupt chaining a) allows cpu to defer processing of low-priority interrupts without masking all interrupts. b) splits interrupt management between first level and second level interrupt handlers. c) is used to handle interrupts but not exceptions. d) is a compromise between the overhead of a huge interrupt table and the inefficiency of dispatching to a single interrupt handler.
The inefficiency of dispatching to a single interrupt handler and the overhead of a large interrupt database are both addressed by interrupt chaining. The right answer is option (d).
The host reads a control register from an I/O device control to obtain input.
How can the CPU manage interrupts?
The majority of current broad sense microchips handle impulses in a similar manner. The CPU switches to a region in memory that either contains the interrupt handling code or an instruction branching to the interrupt handling code when a hardware interrupt occurs, interrupting the execution of the instructions it was currently running.
What interruption is given priority?
With the exception of the divided by zero occurrence, TRAP is the internal interrupt with the greatest priority.
