8. What is Queue? Explain enqueue() and dequeue() algorithm.
A queue is a linear data structure that follows the FIFO (First In, First Out) principle.
The element inserted first will be removed first, just like a line of people waitng for
a service. It has two main operations: enqueue() – to add an element at the rear.
dequeue() – to remove an element from the front.
enqueue() Operaon: Algorithm (using array):
1. Check if the queue is full (rear == size - 1).
2. If not full, increment rear.
3. Insert...
The shoulder joint, also known as the glenohumeral joint, is a ball-and-socket type synovial joint that allows a wide range of motion in the upper limb. Here’s a breakdown of its key features:
Humerus – the upper arm bone; its head forms the "ball."
Scapula (shoulder blade) – contains the glenoid cavity, which forms the "socket."
Clavicle (collarbone) – indirectly involved, connecting the shoulder to the axial skeleton via the acromioclavicularand sternoclavicular
1) Función de utilidad esperada y distribución del riesgo
i) Demuestre en qué condiciones la tasa marginal de sustitución de la riqueza entre estados de la naturaleza es decreciente y qué significado tiene esta característica en la conducta frente al riesgo.
La tasa marginal de sustitución entre dos situaciones posibles de riqueza será decreciente si, al variar c1, la segunda derivada de la función de utilidad con respecto a c1 es negativa. Esto ocurre porque dicha derivada representa cómo
2.5 quintillion bytes of data are generated every day by users. Predictions by Statista suggest that by the end of 2021, 74 Zettabytes( 74 trillion GBs) of data would be generated by the internet. Managing such a vacuous and perennial outsourcing of data is increasingly difficult. So, to manage such huge complex data, Big data was introduced, it is related to the extraction of large and complex data into meaningful data which can't be extracted or analyzed by traditional methods.
For example, Azure
Edema is the abnormal accumulation of fluid in the interstitium or body cavities due to an imbalance in fluid homeostasis.
Types include pitting edema, caused by protein deficiency, increased hydrostatic pressure, increased capillary permeability, or fluid retention; and non-pitting edema, caused by lymphatic obstruction or hypothyroidism (myxedema).
Pathogenesis involves decreased plasma oncotic pressure, increased capillary hydrostatic pressure, lymphatic obstruction, increased
M5). Outline Important Cloud Platform Capabilities. ?
1. On-Demand Self-Service :Users can access computing resources (like servers, storage) whenever they need, without human help.
2. Broad Network Access :Services are available over the internet and can be used from laptops, phones, or tablets.
3. Resource Pooling :Cloud providers share resources (like storage, memory) among many users using virtualization.
4. Rapid Elasticity :Resources can be increased or decreased quickly based on need (auto-scaling)
*Free Space Management:*
Free space management involves tracking and managing unused storage space to optimize allocation and minimize waste.
*Techniques:*
1. *Bit Vector*: Use a bit vector to track free and allocated blocks.
2. *Linked List*: Use a linked list to track free blocks.
3. *Grouping*: Group free blocks together for efficient allocation.
*Benefits:*
1. *Efficient Allocation*: Quickly find free space for allocation.
2. *Reduced Fragmentation*: Minimize fragmentation by efficiently managing
*File System Structure:* A file system structure typically consists of: 1. *Boot Block*: Contains boot information.
2. *Super Block*: Contains metadata about the file system. 3. *Inode Table*: Contains inode structures for each file. 4. *Data Blocks*: Store file data. 5. *Directory Blocks*: Store directory information.
*Key Components:*
1. *Inodes*: Contain file metadata (ownership, permissions, location).
2. *File Descriptors*: Identify open files.
3. *Directory Entries*: Map file names to inodes.
*Memory Management Strategies:*
1. *Partitioning*: Divide memory into fixed or variable-size partitions.
2. *Paging*: Divide memory into fixed-size blocks (pages).
3. *Segmentation*: Divide programs into logical segments (code, data, stack).
4. *Swapping*: Temporarily move processes from main memory to secondary storage.
5. *Contiguous Memory Allocation*: Allocate contiguous blocks of memory to processes.
*Goals:*
1. *Efficient memory use*
2. *Prevent memory fragmentation*
3. *Improve system performance*
