Computer Fundamentals

The binary number system is base-2, meaning it uses exactly two digits: 0 and 1.

Digital computers operate using electrical signals that are either on or off, which corresponds to the binary system.

A binary digit is commonly referred to as a bit, which is a contraction of 'binary digit'.

Hardware refers to the physical, tangible components of a computer system, such as the monitor, keyboard, and internal circuitry.

The binary system is a base-2 system that uses only the digits 0 and 1 to represent all values.

A keyboard is used to enter data into the computer, making it an input device.

Registers are small, high-speed storage locations within the CPU used to hold data temporarily during processing.

A printer takes digital information from the computer and produces a physical copy, which is an output operation.

Magnetic disks, such as hard drives, are used for long-term data retention, classifying them as storage devices.

The claimed answer 'computer organization' is incorrect. Computer organization refers to how hardware components are connected and operate at the physical level. The study of these operations and connections is typically called 'computer organization' or 'computer architecture'. However, 'computer organization' vs 'computer architecture' has subtle distinctions that make this question potentially ambiguous.

Computer architecture refers to those attributes of a system that have a direct impact on the logical execution of a program, such as the instruction set and addressing modes. Computer organization refers to the physical implementation of these architectural concepts.

The Central Processing Unit (CPU) is the primary component of a computer that performs most of the processing inside the computer.

The Control Unit (CU) is a component of the CPU that directs the operation of the processor by telling the computer memory, ALU, and input/output devices how to respond to the instructions sent to the processor.

The control unit is responsible for the instruction cycle, which includes both fetching instructions from memory and coordinating their execution by other parts of the system.

Software refers to the collection of programs, instructions, and data that tell a computer how to perform specific tasks, as opposed to the physical hardware.

Registers are small, extremely fast storage locations within the CPU used to hold temporary data and instructions for immediate processing.

An assembler is a specific type of translator that converts assembly language code into machine language (binary) that the computer processor can execute.

RAM (Random Access Memory) is volatile memory that allows the CPU to both read data from and write data to it during operation.

Option 4 is the correct answer.

RAM is random access memory

 Option 2 is the correct answer.

Option 3 is the correct answer.

Option 1 is the correct answer.
