Answer:
Explanation:
The arithmetic logic unit (ALU) performs mathematical, logical, and decision operations. It can be divided into the arithmetic unit (responsible for addition, subtraction, multiplication and division). And logic unit (responsible for comparing, selecting, matching and merging different data or information). The power and efficiency of the CPU depends on the design of the ALU.
Next up is the control unit (CU) which directs all the processor’s operations. It’s where the CPU reads and interprets requests from memory and transforms them into a series of signals (binary). Then it sends the operation to various parts of the laptop as instructed. The CU calls the ALU to perform the necessary calculations. It also coordinates all input/output devices to transfer or receive instructions.
The main job of the memory unit is to store data or instructions and intermediate results. It’s divided into primary memory and secondary memory to supply data to other units of the CPU. It allows the CPU to perform functions requested by programs like the operating system without having to ask RAM.
Another element of the CPU not depicted in the diagram is transistors. To carry out calculations, binary information (ones and zeros) is stored in these microscopic switches. They control the flow of electricity depending on whether the switch is ON or OFF. Signals turn off and on different combinations of transistors to perform calculations. A very thin silicon chip can contain several hundred million transistors.

Answer:
•Make sure doorway openings are at least 32 inches wide and doorway thresholds are no higher than 1/2 inch.
•Keep aisles wide and clear for wheelchair users.
•Make sure all levels of the lab are connected by a wheelchair-accessible route of travel.
For students with mobility impairments, make sure there are procedures in place for retrieving materials that may be inaccessible.
Make sure ramps and/or elevators are provided as an alternative to stairs. Elevators should have both auditory and visual signals for floors. Elevator buttons should be marked in large print and Braille or raised notation and easily reachable for wheelchair users.
Locate the lab near wheelchair-accessible restrooms with well-marked signs.
Service desks need to be wheelchair-accessible.
Provide ample, high-contrast, large-print directional signs throughout the lab. Mark equipment in the same fashion.
Provide study carrels, hearing protectors, or private study rooms for users who are easily distracted by noise and movement around them.
Provide at least one adjustable-height table with easily reachable controls for each type of computer.
Have wrist rests available to those who require extra wrist support while typing.
Keep document holders available to help users position documents for easy reading.

{
String name;
double salary;
void tostring()
{
System.out.println("Employee:\nName: "+name+"\nSalary: "+salary+"\n");
}
Employee(String n,double s)
{
name=n;
salary=s;
}
}
class Manager extends Employee
{
String department;
void tostring()
{
System.out.println("Manager:\nName: "+name+"\nDepartment: "+department+"\nSalary: "+salary+"\n");
}
Manager(String n,double s,String d)
{
super(n,s);
department=d;
}
}
class Executive extends Manager
{
void tostring()
{
System.out.println("Executive:\nName: "+name+"\nDepartment: "+department+"\nSalary: "+salary+"\n");
