This document discusses different types of computer languages. It begins by defining natural language and computer language, noting that computer languages have a more limited vocabulary than natural languages. It then classifies computer languages into machine language, assembly language, and high-level languages. Machine language uses binary and has no translation, while assembly language substitutes mnemonics for machine codes. High-level languages are problem-oriented and translated into multiple machine codes. Assemblers translate assembly languages, compilers translate high-level languages, and interpreters translate high-level languages line-by-line before executing each one. High-level languages are more machine independent, easier to use and maintain than lower-level languages.
Abstraction level taxonomy of programming language frameworksijpla
The main purpose of this article is to
describe the taxonomy of computer languages according to the levels
of abstraction. There exists so many computer languages because of so many reasons like the evolution of
better computer languages over the time; the socio

# Internet Security: Safeguarding Your Digital World
In the contemporary digital age, the internet is a cornerstone of our daily lives. It connects us to vast amounts of information, provides platforms for communication, enables commerce, and offers endless entertainment. However, with these conveniences come significant security challenges. Internet security is essential to protect our digital identities, sensitive data, and overall online experience. This comprehensive guide explores the multifaceted world of internet security, providing insights into its importance, common threats, and effective strategies to safeguard your digital world.
## Understanding Internet Security
Internet security encompasses the measures and protocols used to protect information, devices, and networks from unauthorized access, attacks, and damage. It involves a wide range of practices designed to safeguard data confidentiality, integrity, and availability. Effective internet security is crucial for individuals, businesses, and governments alike, as cyber threats continue to evolve in complexity and scale.
### Key Components of Internet Security
1. **Confidentiality**: Ensuring that information is accessible only to those authorized to access it.
2. **Integrity**: Protecting information from being altered or tampered with by unauthorized parties.
3. **Availability**: Ensuring that authorized users have reliable access to information and resources when needed.
## Common Internet Security Threats
Cyber threats are numerous and constantly evolving. Understanding these threats is the first step in protecting against them. Some of the most common internet security threats include:
### Malware
Malware, or malicious software, is designed to harm, exploit, or otherwise compromise a device, network, or service. Common types of malware include:
- **Viruses**: Programs that attach themselves to legitimate software and replicate, spreading to other programs and files.
- **Worms**: Standalone malware that replicates itself to spread to other computers.
- **Trojan Horses**: Malicious software disguised as legitimate software.
- **Ransomware**: Malware that encrypts a user's files and demands a ransom for the decryption key.
- **Spyware**: Software that secretly monitors and collects user information.
### Phishing
Phishing is a social engineering attack that aims to steal sensitive information such as usernames, passwords, and credit card details. Attackers often masquerade as trusted entities in email or other communication channels, tricking victims into providing their information.
### Man-in-the-Middle (MitM) Attacks
MitM attacks occur when an attacker intercepts and potentially alters communication between two parties without their knowledge. This can lead to the unauthorized acquisition of sensitive information.
### Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) Attacks

Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors.
Wireless communication is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal through wireless communication technologies and devices.
Features of Wireless Communication
The evolution of wireless technology has brought many advancements with its effective features.
The transmitted distance can be anywhere between a few meters (for example, a television's remote control) and thousands of kilometers (for example, radio communication).
Wireless communication can be used for cellular telephony, wireless access to the internet, wireless home networking, and so on.

4. Difference between natural
language and computer language
Natural language has a very large
vocabulary whereas computer
languages mostly have a very limited
vocabulary.
6. Machine Language
Fundamental language understood
by computer.
Also known as Machine Code.
Written as strings of binary 0’s and 1’s.
No translation program is required.
Not really easy to learn.
7. Instruction Format
Instruction prepared in machine language
has 2 parts
Operation Code: Specifies operation to
be performed.
Operand: specifies address of
operand.
Opcode Operand
(Operation Code) (Address)
8. Advantages of Machine
Language
Programs written in machine language
are very fast to execute as
instructions written in Machine
language are directly understood by
CPU and no translation program is
required.
10. Assembly Language
To simplify the program writing
process used in machine language,
the numeric operation codes of
Machine language were substituted by
letter symbols(Mnemonics).
11. Mnemonics
It is any kind of mental trick we use to
help us remember.
For example: machine code of 111
can be interpreted as subtract but it is
still easier for us to remember it as
SUB.
12. Addition of two numbers

13. Assembly Language
The language which substitutes letters
and symbols for the numbers in the
machine language program is called
an ASSEMBLY LANGUAGE or
SYMBOLIC LANGUAGE.
14. Assembler
The translator program that translates an
assembly code into machine code is
called an Assembler.

15. Advantages of Assembly Language over
Machine Language
Easier to understand and use.
Easy to locate and correct errors.
Easier to modify.
No worry about addresses.
16. Limitations of Assembly
Language
Machine dependent.
Knowledge of hardware required.
Machine and Assembly Languages
being machine dependent are called
as Low Level Languages.
17. High Level Language(HLL)
High level languages instead of being machine
based are oriented more towards the problem to be
solved.
HLL are basically symbolic languages that use
English words and/or mathematical symbols rather
than Mnemonic codes.
HLL are known as Problem Oriented Languages.
Every instruction written in HLL is translated into
many machine language instructions. This is one to
many translation whereas in Assembly Language
there is one to one translation.
18. Compiler
The translator program that translates the
instructions of HLL into Machine Language
is called Compiler.

19. Interpreter
An Interpreter is a type of translator used for translating HLL into
Machine Code.
It takes one statement of HLL and translates it into a Machine
instruction which is immediately executed.

20. Difference between Interpreter
and a Compiler
In case of Compiler, whole source program is translated into
equivalent machine language program. The object code thus
obtained is permanently saved for future use. So, repeated
compilation is not necessary whereas in Interpreter no object
code is saved because translation and execution process
alternate.
Advantage of an Interpreter over Compiler is that it
responses fast to changes in source program.
Interpreters are easy to write and do not require large
memory space.
Disadvantage of interpreter over compiler is that interpreter
is a time consuming translation method because each
statement must be translated every time it is executed from
source program.
21. Assemblers, Interpreters and
Compilers are System Software that
translate a source program into object
program and are known as Language
Processors.
22. Advantages of High Level
Languages
Machine independent.
Easy to learn and use.
Fewer errors.
Easier to maintain.
