True, DoS (Denial of Service) attacks are designed to flood a network server with thousands of requests for service, overwhelming the system and causing it to slow down or even crash.

This is achieved by sending a large volume of traffic to a server or website, often from multiple sources, with the aim of consuming all available resources and making it impossible for legitimate users to access the service. DoS attacks can be carried out using a variety of techniques, such as flooding the network with bogus requests, exploiting vulnerabilities in the server software, or using malware to hijack a large number of computers and use them to launch an attack.

The impact of a DoS attack can be severe, with businesses and organizations losing revenue and customers, and in some cases, suffering irreparable damage to their reputation. Preventing these types of attacks requires a multi-layered approach, including implementing firewalls and intrusion detection systems, monitoring network traffic for unusual patterns, and keeping software and security systems up to date. It is also important for organizations to have a plan in place for responding to DoS attacks, including procedures for isolating affected systems, restoring service, and identifying the source of the attack to prevent future incidents.

False. The modulus operator does not have the highest precedence and is not evaluated first. In most programming languages, operators have a specific order in which they are evaluated, called operator precedence. The order of precedence generally follows the standard mathematical order of operations (PEMDAS/BODMAS), with some variations depending on the programming language.

The highest precedence is typically given to parentheses, which are used to group expressions and force a specific evaluation order. Following parentheses, the next highest precedence operators are usually exponentiation (raising to a power), followed by multiplication, division, and modulus operators, which have the same level of precedence. Addition and subtraction operators come next in precedence.

When operators have the same precedence level, they are evaluated from left to right according to their position in the expression (called associativity). As a result, the modulus operator is not evaluated first unless it appears in parentheses or comes before other operators with equal precedence in the expression.

The three major activities of an operating system with regard to memory management are allocation, deallocation, and protection.

Allocation refers to the process of assigning a portion of the memory to a process or application that requests it. The operating system must keep track of which portions of the memory are currently in use and which ones are free. When a process or application requests memory, the operating system must locate a free portion of memory and allocate it to the process.

Deallocation refers to the process of freeing up memory that is no longer in use by a process or application. When a process terminates or no longer needs a portion of memory, the operating system must free up that memory so that it can be used by other processes or applications.

Protection refers to the mechanisms that the operating system uses to prevent processes or applications from accessing memory that they are not supposed to. The operating system must ensure that each process can only access the portions of memory that it has been allocated and that it cannot interfere with the memory used by other processes.

Overall, memory management is a crucial aspect of operating system design, as it ensures that processes and applications can efficiently use the available memory without interfering with each other.
