Answer:
1GL: Machine language. Represented by a series of 1s and 0s.
2GL: Assembly language. An assembler converts 2GL into machine language.
3GL: High-level programming language. Uses a compiler to convert into machine language.
4GL: Specifically designed for creating database management programs.
5GL: Extremely advanced. Uses statements (scripts) rather than algorithms.
Explanation:
Programming languages started as a series of binary digits (i.e. 0's and 1'). This generation of language is referred to as the first generation.
However, the machine language were difficult to read by human, so mnemonics were created (i.e. assembly language). This language uses symbolic codes such as ADD for addition, etc. This is the second generation
The third generation are the high level languages that uses languages that can be easily understood by human, e.g. + means plus. However, the language must be translated; hence the need for a compiler or interpreter, as the case may be.
The fourth and fifth generations are extensions of the third generation languages. The fourth were created to connect to DBMS while the fifth are more advanced.
Answer: Option (A) & (D) are correct.
Layer 2 switch is commonly referred to as a type of network or device switch that tends to work on data link layer and use MAC addresses in order to determine the route through which the frames are forwarded.
An IDS known as intrusion detection system is commonly referred to as a device or application that controls a network for malevolent activity and its policy violations.
Answer:
The answer is "The program can also be expressed as a binary code, but it is easier for people to understand when it is expressed in a higher programming language".
Explanation:
In the given question some details are missing that is options of the question that can be given as follows:
A. The program can also be expressed as a binary code, but it is easier for people to understand when it is expressed in a higher programming language.
B. The program can also be represented as a binary code that reduces the likelihood of errors.
C. Binary code can not be used for binary code, because binary code can only represent data.
D. Some parts of the program, however, should be printed in a higher-level language for the operation.
The computer knows the only binary language, It is a form of 0 and 1, but this language can't be understood by the user. It will convert into high-level language, that is understood by the user, that's why this option is correct. In which accepts of option A, all options are wrong that can be described as follows:
- In option B, It is wrong, because the user may not understand binary language, and he can also be writing some wrong code that is converted in binary code, that will increase error.
- In option C and option D, is incorrect because all the data that is stored in the computer is in the form of binary code.
The appropriate response is Electrical Switches. These are electromechanical gadgets that are utilized as a part of electrical circuits to control, recognize when frameworks are outside their working reaches, flag controllers of the whereabouts of machine individuals and work pieces, give a way to manual control of machine and process capacities, control lighting, et cetera.
