What year was the first stored-program computer invented
- A.
  
  In 1947
- B.
  
  In 1948
- C.
  
  In 1949
- D.
  
  In 1950
Correct Answer
C. In 1949

Explanation
The first stored-program computer was invented in 1949. This means that it was the first computer that could store and manipulate instructions and data in its memory, allowing it to perform a variety of tasks without needing to be rewired. This invention marked a significant advancement in computer technology and laid the foundation for the development of modern computers.

What was the language of the early programs?
- A.
  
  Number series
- B.
  
  Letters
- C.
  
  Machine codes
- D.
  
  Codes
Correct Answer
C. Machine codes

Explanation
The language of the early programs was machine codes. Machine codes are a low-level programming language that consists of binary instructions understood by the computer's hardware. Early computers were programmed directly in machine codes, which required the programmer to write instructions using binary digits. This was the earliest form of programming language before higher-level languages, such as assembly language and then high-level languages, were developed.

What is a binary number?
- A.
  
  It's a number expressed in the base-3 numeral system that only uses 2 symbols
- B.
  
  It's a number expressed in the base-1 numeral system that only uses 2 symbols
- C.
  
  It's a number expressed in the base-2 numeral system that only uses 2 symbols
- D.
  
  It's a number expressed in the base-2 numeral system that only uses 4 symbols
Correct Answer
C. It's a number expressed in the base-2 numeral system that only uses 2 symbols

Explanation
A binary number is a number expressed in the base-2 numeral system, which means it uses only two symbols: 0 and 1. In the binary system, each digit represents a power of 2, and the value of the number is calculated by adding up the values of the digits. This system is commonly used in computer science and digital electronics, as it is the foundation for representing and manipulating data in binary form, which can be easily understood and processed by computers.

What's the abbreviation for an assembly language?
- A.
  
  Asz
- B.
  
  Azs
- C.
  
  Amm
- D.
  
  Asm
Correct Answer
D. Asm

Explanation
The abbreviation for an assembly language is "asm." Assembly language is a low-level programming language that is closely related to machine language. It uses mnemonic codes to represent instructions and allows direct control over the computer's hardware. The abbreviation "asm" is commonly used in the field of computer programming to refer to assembly language.

Who invented the first compiler for a programming language?
- A.
  
  Anna Hopper
- B.
  
  Grace Kopper
- C.
  
  Grace Popper
- D.
  
  Grace Hopper
Correct Answer
D. Grace Hopper

Explanation
Grace Hopper is the correct answer because she is widely recognized as the inventor of the first compiler for a programming language. She developed the A-0 system, which was the first compiler, in the early 1950s. Hopper's work revolutionized programming by allowing programmers to write code in a high-level language and have it automatically translated into machine code. Her contributions to computer science and programming have had a lasting impact and she is often referred to as the "Mother of COBOL."
