2. a.
Briefly explain the classes of language translators given at-least an example for each
b. Define communication software and briefly explain the types of communication software citing relevant examples
C. State any four advantages of mesh topology you know.
a. The classes of language translators are:
1. Compiler: It translates the entire source code of a program written in a high-level programming language into a machine code executable file. For example, the GCC compiler translates C code into machine code that can run on a specific operating system.
2. Interpreter: It translates and executes the source code line by line, without creating an executable file. It interprets each instruction at runtime. For example, the Python interpreter translates and executes Python code on the spot, without creating an executable file.
b. Communication software is a category of software that enables communication between two or more parties over a network. The types of communication software are:
1. Instant Messaging (IM) software: Examples include WhatsApp, Facebook Messenger, and Slack. These software applications allow real-time text-based communication between individuals or groups.
2. Voice over Internet Protocol (VoIP) software: Examples include Skype, Zoom, and Microsoft Teams. These applications allow users to make voice and video calls over the internet, often providing features like screen sharing and conference calling.
3. Email client software: Examples include Microsoft Outlook, Gmail, and Thunderbird. These software applications enable users to send, receive, and manage email messages.
c. Four advantages of mesh topology are:
1. Fault tolerance: Mesh topology offers high reliability and fault tolerance because each device is connected to multiple devices. If one link or node fails, alternative paths can be used to maintain connectivity.
2. Scalability: It is easy to add new devices or nodes to a mesh network, making it highly scalable. Each device only needs to be connected to a few neighboring devices.
3. Data transmission efficiency: In a mesh network, data can be transmitted directly between devices without the need for intermediate routing, resulting in efficient data transmission and lower latency.
4. Security: Mesh topology offers enhanced security as there is no single point of failure. Even if one or more devices are compromised, other devices in the network can still operate independently.
