Answer:
Reverse Phishing and Scareware
Explanation:
Ransomware is a type of malware that denies access to data files using encryption until a ransom is paid. It comes under the category of cyber extortion. Ransomware does not intend to cause any damage to the computer’s file system instead, it displays a ransom note on the victim’s screen so that the victim can pay a certain amount of money to remove the restrictions and regain access to their computer, usually via a key. The malware creator will either supply a program that can decrypt the files, or will send an unlock code that decrypts the victim’s data. But there is no guarantee that this will happen, even if the requested ransom is paid.
Types of Ransomware
The two major types of ransomware are:
Crypto-Ransomware
Locker Ransomware
Types of Ransomware
Types of Ransomware
Crypto Ransomware:
Crypto ransomware aims to encrypt sensitive files on the victim’s computer. It does not block any basic computer function. This ransomware searches for important files on the local hard drive and external drives of the victim’s system and starts encrypting them. Then, it will present a ransom note to the victim, showing a countdown timer and asking for payment. The attackers generate income by holding the valuable files hostage and demanding a ransom through anonymous methods such as Bitcoin to regain access to these files.

Locker Ransomware:
Locker ransomware locks the victim out of their device and blocks basic computer functions. Some parts of the keyboard may be locked and the mouse can be frozen allowing the victim only to respond to the attacker’s demands. In this case, attackers demand ransom to unlock the device. The locked system only allows limited access, to interact with the attacker.

Validate the user's input so that only pay rates in the range of $7.50 through $18.25 and hours in the range of 0 through 40 are accepted. The program should display the employee's gross pay.
The payroll program that prompts the user to enter an employee's hourly pay rate and the number of hours worked is made with the help of Do While loop.
What is Program?A sequence or set of instructions written in a programming language for a computer to follow is called a computer program. Software includes documentation and other intangible components in addition to computer programs. Source code is the human-readable version of a computer program. Because computers can only execute their own native machine instructions, source code must be executed by another computer program.
Given to make a payroll program,
Program is made with Do While loop,
A condition and a process symbol make up the do while construct. First, the block's code is executed. After that, the situation is looked at. The block's code is executed once more if the condition is met. This continues until the condition is true.
The program code is,
Do While payRate > 7.5 AND payRate < 18.25
Display "Enter hourly pay rate: "
Input payRate
End While
Do While hoursWorked > 0 AND hoursWorked < 40

a system uses simple/pure paging and tlb each memory access requires 100ns tlb access requires 5ns tlb hit rate is 90%. work out the actual speedup because of the tlb? speedup
Each process in the operating system will have its own page table, which will contain Page Table Entry (Memory Management Technique: Paging) (PTE).
What is Translation Lookaside Buffer (TLB) in Paging?The frame number (the address in main memory to which we want to refer) and a few other essential bits (such as the valid/invalid bit, dirty bit, protection bit, etc.) will be included in this PTE. This page table entry (PTE) will indicate where the actual page is located in main memory.The issue now is where to put the page table such that overall access time (or reference time) will be less.Fast main memory content access using a CPU-generated address (i.e., a logical or virtual address) presented a challenge at first. Since registers are high-speed memory, some people at first considered utilizing them to store page tables since access times would be shorter.The concept employed here is to store the page table entries in registers, so that when a request is created from the CPU (virtual address), it will be matched to the correct page number of the page table, which will then reveal where in the main memory the corresponding page is located.Everything appears to be in order, but the issue is that the register size is small (in practice, it can only hold a maximum of 0.5k to 1k page table entries) and the process size may be large, so the required page table will also likely be large (let's say this page table contains 1M entries). As a result, the registers might not be able to hold all of the PTEs of the page table. Therefore, this strategy is not workable.The Complete Question is Page Table Entry.

g consider the following delays for computation in each of the pipeline stages in a mips processor: given this, what is the latency of a load instruction in a five stage pipelined implementation of this mips processor?
When a pipeline is used, the cycle time is reduced to the longest stage's length plus the register delay. Due to the fact that each stage requires one cycle and that one instruction must pass through each one, latency is defined as CT*N, where N is the number of stages.
What is latency in pipeline?The phrase "instruction latency" should be introduced before we wrap up our study of pipeline delays. You'll come across it several times in the remaining sections of this essay. The number of clock cycles needed for an instruction to complete its pipeline traversal is known as its latency. All instructions for a processor with a single clock cycle have the same delay. As opposed to this, all instructions in the straightforward four-stage pipeline that has been presented so far have a four-cycle latency. Similarly, instructions on an eight-stage pipeline have a latency of eight cycles, those on a twelve-stage pipeline of twelve cycles, and so forth.The number of pipeline steps is not always a set number in real-world CPUs, and neither is the instruction delay.Each extra cycle that instructions spend waiting in a pipeline stage increases their delay by one cycle since instructions may become stuck in one or more pipeline stages for numerous cycles. As a result, the instruction latencies listed above, such as four cycles for a pipeline with four stages, eight cycles for a pipeline with eight states, etc., are the minimum instruction latencies. Depending on whether or not an instruction pauses in one or more stages, actual instruction latencies in pipelines of any length may exceed the depth of the pipeline.To Learn more About pipeline refer to:

The central administration of applications and data is a significant benefit of the client-server network. A client-server network speeds up data transfer while also securing the data sent.
Using the network is a wise choice for organizations seeking faster and more secure data transport. Because the files are centralized, it is easier to perform consistent file backups. File duplication is no longer a concern, and the security issues associated with peer-to-peer networks are eliminated because everyone on the network just needs access to the central server. When establishing a P2P network, there is no need to purchase a separate computer to function as a server.
