Answer:
Highest
Explanation:
A interrupt request / IRQ is in which instructions are sent to Cpu and uses an interrupt handler to run distinct program . Hardware interrupts are used to manage occurrences such as obtaining modem or network card information, important presses, or mouse motions.
- Interrupt request 0. – it is a system timer (can not be altered)
- Interrupt request 1 – keyboard controller (can not be changed)
- Interrupt request 2 – cascaded IRQ 8–15 signals (any device configured to use IRQ 2 will genuinely use IRQ 9)
- Interrupt request 3 – serial port 2 controller
- Interrupt request 4 – serial port 1 controller
- Interrupt request 5 –parallel port 2 and 3
- Interrupt request 6 - floppy disk controller
- Interrupt request 7 –parallel port 1. If a printer is not present, it is used for printers or for any parallel port. It can also possibly be shared with a secondary sound card with cautious port management.
As interrupt number increases priority level decreases, Priority level 0 is the highest priority level .
Generation in computer terminology is a change in technology a computer is/was being used. Initially, the generation term was used to distinguish between varying hardware technologies. Nowadays, generation includes both hardware and software, which together make up an entire computer system.
Generation & Description
1 First Generation
The period of first generation: 1946-1959. Vacuum tube based.
2 Second Generation
The period of second generation: 1959-1965. Transistor based.
3 Third Generation
The period of third generation: 1965-1971. Integrated Circuit based.
4 Fourth Generation
The period of fourth generation: 1971-1980. VLSI microprocessor based.
5 Fifth Generation
The period of fifth generation: 1980-onwards. ULSI microprocessor based.

Answer:
Security of the computer systems is becoming more crucial as the days go by due to events that threatens the safety and security of these computers, the internet and the resources shared on them.Security professionals are those people who have the necessary skill set to handle the security situation of the computers and network and can both maintains these systems and resolve any security issue.
In light of the skill sets that they posses, they work for firms or they work on their own to maintain security. In general every skill needs to be revised and these skill is not an exception also there are newer threats and security issues which are arising every day hence there is need to maintain competence in their field which requires undergoing training and practice to handle the latest security threats that is constantly evolving each day.Due to the issue of budget constrains the security professionals can take the following actions in order to be able to participate in training:
- Involve themselves in taking online courses over the internet
- They can acquire self education materials , researches and case studies on both recent and past security events
- They also engage in peer guidance and mentoring which would work in a vise versa way for information and knowledge exchange
- participating in "hackathons" and competitions as a way for them to identify the features and skill set to improve
Explanation:
The question requires explanation so instead of answering the question by stating the points we first give a brief description of the state of digital security in the world.Next we now talk about the security professionals ( who they are and what they do). Finally we then discuss about the need for training for these professionals and how these security professionals can access these training in a situation where there is a budget constrain issue
