ELEMENT DEFINITIONS

• Instruction set: A collection of commands that a CPU can understand and execute. It defines the operations the processor can perform.
• Bus: A communication system that transfers data between components inside a computer, or between computers.
• Clock speed: The rate at which a processor executes instructions, measured in cycles per second (Hertz). A higher clock speed generally means faster processing.
• Bandwidth: The maximum rate of data transfer across a given path or network. It indicates how much data can be sent in a fixed amount of time.
• Word length: The number of bits that a CPU can process at one time. It determines the size of data units the processor handles.

QUESTION 5

a) A microprocessor is an integrated circuit that contains the entire central processing unit (CPU) functions of a computer on a single chip. It performs arithmetic, logic, and control operations.

b) The elements found in a microprocessor include:

• Arithmetic Logic Unit (ALU)
• Control Unit (CU)
• Registers
• Internal buses

c) The function of an input/output (I/O) device is to allow a computer to interact with the outside world by receiving data (input) or sending data (output).
Two examples of an input/output device are:

• Touchscreen (input and output)
• Network Interface Card (NIC) (input and output)

QUESTION 6

A) A digital circuit is an electronic circuit that operates using discrete voltage levels to represent logical states, typically binary 0 and 1. These circuits process information in digital form.

B) The difference between a digital circuit and an analog circuit is that a digital circuit processes discrete signals (e.g., binary 0s and 1s), while an analog circuit processes continuous signals that can take any value within a range.

C) Three characteristics of a digital system are:

• High accuracy and precision
• Ease of design and implementation
• Less susceptible to noise

D) Four applications of a digital system are:

• Computers and smartphones
• Digital cameras
• Medical imaging equipment
• Industrial control systems

E) Two components that are found in an Integrated Circuit (IC) are:

• Transistors
• Resistors
