A bit (binary digit) is the smallest and most fundamental unit of data in computing. It represents a single binary value, either a 0 or a 1. All other units of digital data, such as bytes, kilobytes, megabytes, etc., are made up of combinations of bits. A byte, for example, is composed of 8 bits.

The CPU (Central Processing Unit) is the "brain" of the computer, responsible for executing instructions. It performs this task through a repetitive cycle: Fetch, Decode, Execute. This cycle repeats continuously, allowing the CPU to process a large number of instructions in a short period, enabling the computer to perform tasks and run programs.

USB drives are commonly used for storage, data backup, and transferring files between devices. USB drives come in multiple storage capacities and different ports, each having a unique shape. Using a USB drive can differ depending on the type of computer that you want to connect to. A typical USB drive is removable, rewritable, and smaller than an optical disc.

Answer: (D) Design code
Computer code refers to the instructions that a computer can understand and execute. Source code is human-readable code written by programmers using a high-level programming language (e.g., Python, Java, C++).Object code is the output of a compiler after translating source code into machine-readable instructions, but it's not yet executable on its own and often needs to be linked with other object files. Machine code is the lowest-level programming language, directly executable by a computer's CPU. It consists of binary instructions (0s and 1s).Bytecode is an intermediate form of code that is typically executed by a virtual machine (like the Java Virtual Machine). It's platform-independent.

Answer: (D) Charles Babbage
Answer: (D) Charles Babbage
Charles Babbage was an English mathematician, philosopher, inventor, and mechanical engineer who designed the Difference Engine and, more importantly, the Analytical Engine. The Analytical Engine is considered the conceptual forerunner of the modern digital computer, incorporating features like an Arithmetic Logic Unit (ALU), basic flow control, and integrated memory, which are fundamental to today's computers. Although it was never fully built in his lifetime, his detailed designs and theoretical work laid the foundational principles for future computer development.
