A basic computer is an electronic device that processes data under the control of instructions stored in its memory. It can accept input, process that input, store the results, and output the processed information. Essentially, it's a programmable machine that can perform various tasks by manipulating data. 

Here's a more detailed breakdown:

1. Input: The computer receives data from various sources like a keyboard, mouse, or other input devices.

2. Processing: The computer manipulates this data according to a set of instructions (a program).

3. Storage: The computer can store both the input data and the processed results for later use.

4. Output: The computer presents the processed information to the user, often through a display screen, printer, or other output devices. 

Key Components of a Basic Computer:

Hardware:

The physical parts of the computer, including the CPU (central processing unit), memory (RAM and ROM), storage devices (hard drive), input/output devices, and peripherals. 

Software:

The instructions or programs that tell the computer what to do, such as the operating system and applications. 

In essence, a basic computer takes data, manipulates it according to instructions, stores the results, and presents the output to the user.
