The Picture Clause describes the attributes of a data item, including its type (e.g., numeric, alphabetic), size, and format

COBOL stands for Common Business Oriented Language

Explanation

The C programming language is widely known for its use in system and structured programming.

It provides:

• low-level access to memory
• a simple set of keywords
• a clean style

That makes it highly efficient and suitable for writing operating systems and other system-level software.

Explanation

Programmers use Source code, which is:

• Human-readable and written in a programming language.
• Compiled or interpreted to create machine-readable code.
• Used to develop software, apps, and websites.
• Essential for programming and software development.

Explanation

The Unix shell is a:

• Scripting language: It can execute scripts containing multiple commands.
• Interpreter language: It interprets commands one at a time, without the need for compilation.

Explanation

Machine language is the lowest-level programming language, consisting of binary code that a computer's processor can execute directly. The basic components of a machine language program are:

• Instructions: These are the fundamental commands that a computer's processor can execute, such as move data, perform arithmetic operations, jump to a location, etc. Instructions are represented as binary codes, such as 0s and 1s.

Explanation

• Software that is permanently stored in the BIOS (Basic Input/Output System) of a computer is called Firmware.
• This type of software is typically used to control and configure the hardware components of a computer, such as the keyboard, display, and storage devices.
