Add 2 examples of where they think computers are used to control tasks in everyday life:

• The brain of the system that receives inputs from sensors, processes the data, and sends commands to actuators.

• It controls all operations and decisions in the system based on pre-programmed instructions.

Processors (CPU):

• Devices that detect physical changes in the environment and send this data to the processor.

• Types of sensors include:

  • Temperature sensors (for heating systems),

  • Motion sensors (for security systems),

  • Light sensors (for streetlights),

  • Proximity sensors (used in car parking systems).

​Sensors

• Devices that execute actions based on the commands sent by the processor.

• Actuators can control mechanical movements, such as opening a valve, turning a motor, or changing a display.

• Common examples include robotic arms in factories, motors in elevators, and valves in irrigation systems.

​Actuators

These three components (processors, sensors, and actuators) work together to allow computer-controlled systems to monitor, analyze, and automate processes in various fields.

Advantages of Computer-Controlled Systems

1.High Efficiency:

○Computer-controlled systems can process large amounts of data quickly and make real-time decisions. For example, an automated
manufacturing system can produce thousands of identical products with minimal error and at a faster rate than human workers.

2.24/7 Operation:

○These systems can run continuously without breaks, which is critical in industries like automated production lines or temperature control
systems in buildings that need to operate around the clock.

3.Performing Repetitive Tasks:

○They are ideal for tasks that are repetitive and monotonous, such as painting cars in a factory or sorting items in a warehouse, which would
be tedious and error-prone for human workers.

4.Increased Safety:

○Computer-controlled systems can operate in hazardous environments, such as handling toxic chemicals or working in extreme temperatures,
reducing the risk to human workers.

5.Cost Efficiency in the Long Run:

○Although the initial setup can be expensive, computer-controlled systems don’t need wages, rest, or holidays. Over time, they save money by
reducing labor costs.

6.Error-Free Operations:

○Unlike humans, these systems can perform tasks with precision and consistency, reducing the likelihood of errors. This is particularly useful in
areas such as pharmaceuticals or microchip manufacturing.

​

Disadvantages:

1.High Initial Costs:

○Setting up computer-controlled systems, including buying the hardware and developing the software, can be very costly. For
example, setting up a fully automated production line in a car manufacturing plant requires significant investment in machinery
and software development.

2.Dependence on Power:

○If there is a power failure or system crash, the entire operation halts. For instance, if an automated warehouse loses power, all
operations come to a standstill, whereas human workers might still continue working in low-light conditions.

3.Limited Flexibility:

○These systems are excellent for repetitive tasks but can struggle with unexpected situations. For example, a robot can assemble
parts on a production line, but if there is a defect in a part, it may not be able to adapt to handle the situation as a human worker
would.

4.Maintenance and Upgrades:

○These systems require regular maintenance and software updates to keep them functioning efficiently. If not properly maintained,
breakdowns can lead to costly downtime.

5.Job Redundancy:

○One of the societal concerns with computer-controlled systems, especially in industries like manufacturing, is that they may lead
to job losses as machines replace human workers.
