Explanation

Ada, created by Jean Ichbiah and his team, correctly computes 5^3  as 125.

It is a strong, statically typed language designed for reliability and maintainability in large software systems

Pascal and Smalltalk are not associated with Jean Ichbiah,

Eiffel, developed by Bertrand Meyer, also correctly computes  5^3  as 125.

Explanation

Modern computers are primarily based on transistor technology. 

And old computers are based on vacuum tube

John Vincent Atanasoff invented the first digital computer in 1930. 

Charles Babbage is known as the Father of the Computer.

Explanation

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

Beeps or failure to boot can indicate a hardware or firmware issue, which is typically reported by the BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) firmware during the boot process.

Explanation

• Mortar, Cacrus, and Milosous are not real computer viruses.
• They are likely fictional or made-up names, and are not recognized or known viruses.

Explanation

When you turn on your computer, it will check the control files:

• (Command.com) (Command Interpreter)
• io.sys (Input/Output System file)
• msdos.sys (MS-DOS System file)

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

• In a Star Network Topology, each network node (computer, printer, etc.) is connected to a central device called a hub or switch.
• This central device acts as a connection point for all the nodes, and data transmission occurs through it. 
• This topology is called a star topology because the connections resemble a star, with the hub at the center and the nodes at the points.

Explanation

Telnet is a text-based computer protocol that allows users to remotely access and manage a computer or network device. It uses a command-line interface (CLI) to send and receive text-based commands and responses. Telnet is a client-server protocol, where the user's device acts as the client and the remote device acts as the server.

Telnet is typically used for:

• Remote access to servers, routers, and other network devices
• Command-line interface (CLI) access to network devices
• Troubleshooting and debugging network connections
• Remote execution of commands and scripts
