Answer:
Boot sector virus
Explanation:
A boot sector virus is a virus which functions is to infects the sector of the boot of floppy disks of hard disks in which they use DOS commands to spread to other floppy disks and they tend to either copies the master boot program to another part of the hard disk or try to overwrites it which is why they are said to always infect a computer when it boots up as well as when it accesses the infected floppy disk in the floppy drive. Although BOOT SECTOR VIRUS are difficult to remove because most antivirus programs cannot clean the MBR while the windows is running reason been that it takes bootable antivirus disks to properly remove a boot sector virus.
Hence with BOOT SECTOR VIRUS newer versions do not need to be booted due to the fact that they often have to reside on the removable media, such as on a flash drive especially in a case when the Computer systems are typically infected by these viruses.
Answer:
1. The CPU fetches from the memory the instruction
2. The CPU decodes the instruction
3. The CPU fetches the operands (if needed)
4. The CPU executes the instruction
5. The CPU writes back the result(s)
6. The CPU updates itself to fetch the next instruction (Jump to Step 1)
Explanation:
The instructions are saved in the memory, so they need to be in the processor to get a result. But before doing anything, the CPU must decode it to "understand" it. If the instruction contains any logic or arithmetic operations, the Arithmetic Logic Unit (ALU) will do that job. Then, the CPU executes the instruction and writes back to the memory the result. As the last step, the Program Counter is updated to the memory adress of the next instruction.
Found the same question with the choices;
A. Reason Effectively
B. Solve Problems
C. Communicate Clearly
D. Use System Thinking
I would say the answer is A.
Answer:
All things considered newgrp has nothing to do with security jobs.
newgrp sets the procedures bunch id which is in many frameworks are irrelevant. All gatherings are accessible. Gatherings are characterized as assortment of clients , bunch get to is conceded to documents dependent on the record gathering.
Regularly (setgroups/getgroups ) all gatherings are in the process get to list.
The authorization at a document or registry level has a 3 level arrangement of consents, for example, client proprietorship , bunch possession and others. All things considered the document authorization are a mix of read , compose and execute .we need both peruse and execute consent to run a program.
A procedure may get to the document if a record has a place with the user(the proprietor of the document ) or if the gathering identifier coordinate on the gatherings in the clients bunches list. That entrance is constrained by the relating consents signals on the record.
Gatherings have been over-burden with some "job" definitions. In any case, these are just over-burden and not a decent utilization of groups,the utilization of a gathering as a job was bolstered by the setgroup id banner , and by utilities like a sudo , where gathering name likewise coordinates a security control. It expect that the gathering name isn't utilized for documents yet once a client is in the gathering that client can apply the gathering to a record regardless of whether it isn't what the gathering was for.
This over-burden use worked where frameworks didn't bolster genuine jobs. The over-burden utilize was only a work around.
Linux has genuine job definition bolstered by SELinux models and can be applied to documents , clients , and forms.
