Method overloading

•In Java it is possible to define two or more methods within the same class that share the    same name, as long as their parameter declarations are different.

•Overloaded methods must differ in the type and/or number of their parameters

•When an overloaded method is invoked, Java uses the type and/or number of arguments as its guide to determine which version of the overloaded method to actually call. 

• return type do not play any role in overload resolution

  1. A clock that oscillates 1 million times per second (1 MHz) produces a clock cycle of 1 microsecond (1 μs), which equals 10−6106 seconds per cycle.

  2. The steps of executing a machine instruction are: fetch the instruction, decode it, fetch the operand if any, execute the instruction, and store the result or output.

  3. Cache memory is a small, fast memory used to temporarily store frequently accessed data or instructions to speed up CPU operations. A cache hit occurs when the CPU finds the

[1 mark] A clock that oscillates 1 million times per second (1 MHz), produces a clock cycle with 10-6second. 2. [1 mark] The general-purpose registers that can be accessed in 8 bits, 16 bits and 32 bits are EAX, EBX, ECX and EDX. 3. [2 marks] Write down the purpose of the EAX and ECX registers?  EAX – accumulator: Automatically used by multiplication and division instructions, often called as extended accumulator register.  ECX – loop counter: CPU automatically uses ECX as a loop counter.

There is little doubt that the quality and frequency of our real-life conversations are declining, and social media must be held largely responsible for this shift. While these digital platforms promise connection, their underlying mechanics often undermine the very fabric of genuine communication. The endless pursuit of a perfect online persona weakens the enduring bonds formed through authentic, face-to-face interaction, suggesting that our digital habits are actively harming our social health.
