To calculate the size of the page table, we first need to determine how many entries are required. Since the virtual address is 32 bits and the page size is 1 kb (or 2^10 bytes), the page offset is 10 bits (2^10 = 1 kb). Therefore, the remaining 22 bits are used for the page number.

Each page table entry is 4 bytes, and since there are 2^22 possible pages, we need 2^22 * 4 bytes = 16 MB of memory to store the page table.

If there are 10 programs running on the computer at the same time, each program has its own page table, so there would be 10 page tables in total.

A disadvantage of segmented memory allocation is external fragmentation.

The process of dividing the memory space of a computer system into several portions is known as segmented memory allocation. It's called "segmentation". The number of memory partitions that can be generated is determined by the computer system's capacity. Memory segments, once they've been allocated, are referred to as memory blocks.

A pointer variable is needed to point to the start address of each memory block. When segmentation is used to allocate memory, memory block sizes are varied. When a block of memory is allocated and there is room in the block, memory is kept. External fragmentation can occur as a result of this. External fragmentation is a phenomenon in which a computer system's memory becomes dispersed and unmanageable. In segmented memory allocation, external fragmentation occurs.

The lifetime of an object created on the heap is controlled by the garbage collector, which monitors the object's usage and deletes it when it is no longer being used. This is different from an object created on the stack, which has a predetermined lifetime that depends on the scope in which it was created.

Stack and heap are the two methods of allocating memory for an object in C++ programming language. An object that is created on the heap is dynamically allocated memory. The lifetime of an object created on the heap is determined by the new operator, which creates the object and returns its address, and the delete operator, which destroys the object and frees up memory. Dynamic allocation of memory is done using the heap in the C++ programming language.

Objects that are created on the stack, on the other hand, are statically allocated memory. The lifetime of an object created on the stack is determined by the scope in which it is declared. When the scope in which the object is declared terminates, the object is automatically destroyed.

An individual has chosen the public key of n = 187 = 11 x 17 and e = 3. What is the private key using RSA encryption?The private key is the inverse modulo of `e` over `m`. In other words, `d` is such that `e * d = 1 (mod m)`.To determine `d`, we must first calculate `m`, which is the totient of `n`.

Since `n = 11 * 17`, `m = (11 - 1) * (17 - 1) = 160`.

Next, we must solve for `d` in the equation `3 * d = 1 (mod 160)`. To do this, we can use the extended Euclidean algorithm.

Using the extended Euclidean algorithm: $160 = 3 * 53 + 1$$1 = 160 - 3 * 53$$1 = 160 - 3 * (187 - 11 * 17)$

Therefore, `d = -53 mod 160` or `d = 107`.

Thus, the private key using RSA encryption is `107`.

Semantic segmentation and object detection are two computer vision techniques used for image analysis. The difference between them is in the level of granularity of the analysis. In contrast, semantic segmentation divides the image into a grid of predefined classes and can provide more detailed information about the objects in the image.

Semantic segmentation is a process of dividing an image into different segments, with each segment representing a distinct object or region of the image. In other words, it is a pixel-wise classification of an image, where every pixel is assigned a label that describes the object it belongs to.

Object detection, on the other hand, is the process of identifying and localizing specific objects within an image. Object detection algorithms detect the presence of an object in an image and draw a bounding box around it to indicate its location. This allows for multiple objects to be detected in a single image. In summary, while semantic segmentation deals with pixel-wise classification of an image, object detection is focused on detecting and localizing specific objects within an image.
