Process Control Block
The process control block (PCB) is a data structure used by an operating system to maintain information about a specific process. It is an essential component of process management and contains various details related to a process's execution.
Key Points:
- Process Identification: The PCB contains a unique process identifier (PID) that distinguishes it from other processes running in the system.
- Process State: The PCB stores the current state of the process, such as running, waiting, or terminated. This information allows the operating system to schedule and manage processes effectively.
- Program Counter: The PCB includes the program counter, which keeps track of the next instruction to be executed by the process.
- Registers and CPU Information: The PCB stores the values of various registers (e.g., general-purpose registers, stack pointer, etc.) associated with the process. This information is crucial for context switching and resuming the process's execution.
- Memory Management: The PCB maintains information about the process's memory allocation, including the base and limit registers used for memory protection.
- Open Files: The PCB keeps track of any open files or resources associated with the process. This information is necessary for managing file access and ensuring proper resource utilization.
- Process Priority: The PCB may store the priority of the process, allowing the operating system to allocate resources and schedule processes accordingly.
- Parent-Child Relationship: The PCB includes pointers or references to the process's parent and child processes, enabling the operating system to manage process hierarchies and implement process synchronization or communication mechanisms.
- Accounting Information: The PCB may contain accounting information, such as the amount of CPU time consumed by the process, the amount of memory used, and other performance-related metrics.
Overall, the process control block serves as a comprehensive repository of information about a process, allowing the operating system to effectively manage and control its execution in a multi-tasking environment.

Explanation:
The application of the internet refers to the various ways in which the internet is used in our daily lives. The internet has revolutionized the way we communicate, conduct business, and access information. However, there are certain activities that are not considered as applications of the internet.
Here, the option "D: Sleeping" is not an application of the internet. Sleeping is a biological process and does not involve the use of the internet. The internet cannot be directly used for sleeping purposes.
Applications of the Internet:
A: Communication
- The internet allows people to communicate with each other through various means such as email, instant messaging, video calls, and social media platforms.
- It enables people to connect with others globally, facilitating communication in real-time.
B: Banking
- The internet is widely used for online banking services, allowing individuals to access their bank accounts, make transactions, and manage their finances online.
- It provides convenience and accessibility to banking services from anywhere at any time.
C: Shopping
- Online shopping has become increasingly popular with the advent of the internet.
- It allows consumers to browse and purchase products from various online retailers, making shopping more convenient and accessible.
In summary:
The internet has numerous applications, including communication, banking, and shopping. However, sleeping is not an application of the internet as it does not involve the use of online services or activities.

As 'Table' is made from 'Wood' in the same way 'Shirt' is made from 'Cloth'.

Non-discursive communication refers to any form of communication that does not involve the use of words or language.

• Speaking involves the use of words or language to communicate, which is the opposite of non-discursive communication.
• Non-discursive communication includes forms of communication that do not involve the use of words, such as facial expressions, body language, gestures, and silence.
• It is an important aspect of human communication and can play a significant role in how we interact with others and convey meaning and emotion.

Thus, it is concluded that Speaking is NOT a form of non-discursive communication.

A teacher, after preparing a question paper, checks whether the questions test specific Testing objectives. He is concerned primarily about the question paper's validity.

School and classroom environment is the place where the child's 'cognitive' development is defined in the best way. Schooling has direct effects on children's educational achievement, their acquisition of literacy, numeracy and scientific knowledge. These basic skills provide the foundation for later "subjects" such as geography, physics and foreign languages.

radius = Diameter/2

diameter = √((2-(-3))² + (4-(-1))²)

               = √5²+5² = √50 = 5√2

Given curve is x = t² − 1,y = t² − t
Derivating w.r.to t we get
d x/ dt =2t -------(1)
and  dy / dt = 2t − 1 -------(2)
dividing (2) by (1)  we get
dy / dx = (2t − 1) / 2t
Therefore, the slope of the tangent is  (2t − 1) / 2t
Given that the tangent is perpendicular to x-axis. Therefore, tangent is parallel to y-axis. 
We know that slope of y-axis is infinity and the slopes of the two parallel lines are equal.
Therefore, slope of the tangent is infinity.
Hence, (2t − 1) / 2t = 1/0
⟹ 2t = 0
⟹ t = 0

|A| = 3, |B| = 4, |C| = 5
Since A.(B + C) = B.(C+A) = C(A+B) = 0...........(1)
|A+B+C|² = |A| + |B|² + |C|² + 2(A.B + B+C + C.A)
= 9+16+25+0
from eq(1) {A.B + B+C + C.A = 0}
therefore, |A+B+C|² = 50
=> |A+B+C| = 5(2)^1/2

x² + y²=16 and y² = 6x 
So, to figure out the P.O.I
x² + 6x = 16
x² + 6x – 16 = 0
(x+8) (x-2) = 0
x = -8, 2
For x = -8
y = (6*(-8))^1/2 
= (-48)^1/2 
No real value for y
For x = 2
y = (6*2)^1/2 
= (12)^1/2 
= 2*(3)^1/2 
So, P.O.I is (2 , 2*(3)^1/2 )    

 

None

n1 = 2i + j + k
n2 = 2i + 3j - 4k
p1 = 4,   p2 = -6
r.(n1 + λn2) = p1 + λp2
=> r . [2i + j + k + λ(2i + 3j - 4k)] = 4 - 6λ
=> r . [ i(2 + 2λ) + j(1 + 3λ) + k(1 - 4k)] = 4 - 6λ
Taking r = xi + yj + zk
(2 + 2λ)x + (1 + 3λ)y + (1 - 4k)z = 4 - 6λ
(2x + y + - z - 4) + λ(2x + 3y - 4k + 6) = 0
Given points are (1,2,1) 
(2 + 2 - 1 - 4) + λ(2 + 6 - 4 + 6) = 0
-1 + λ(10) = 0
 λ = 1/10
Substitute  λ = 1/10, we get
18x + 7y + 14z - 46=0

= x+10 = 3x+4
= x = 3

Fact

If A is a symmetric matrix, then B'AB is a symmetric metrix. So, B'AB is a symmetric matrix.

(2,4) written in set builder form is:
{x : 2 < x < 4}

hx + ky - xy = 0
let asymptotes be hx + ky - xy + c = 0 ; This represents a pair of straight lines if Δ =  0
i.e. c =-hk ∴ asymptotes are xh+yk-xy-hk =0 ⇒ (x - k) (y - h) = 0

y = cos² x [0,π]
∫(0 to π/2)cos² xdx + ∫(π/2 to π)cos² xdx
= 1/2∫(1 + cos 2x)
= [½(x + sin(2x)/2](0 to π/2] + [1/2(x + sin(2x)/2](π/2 to π)
= ½|π + 0 - 0 - 0| + 1/2|(π + 0) - π/2|
= π/4 + π/4 = π/2

The given system of equations does not have solution if : 

- 0 ⇒ 1(-14) - 4(-7) -2(7) = 0

 

A relation f from a set A to a set B is said to be function if every element of set A has one and only one image in set B. In other words, a function f is a relation such that no two pairs in the relation has the same first element. The notation f : X →Y means that f is a function from X to Y.
