    Correct Answer
    A. Asynchronous communication
    Explanation
    Asynchronous communication is a form of communication that transmits information as a serial stream of bits or bytes. In asynchronous communication, data is transmitted one bit at a time, with each bit being accompanied by start and stop bits to indicate the beginning and end of a data unit. This type of communication is commonly used in computer networks and telecommunications systems, where it allows for efficient and reliable transmission of data over long distances. Unlike synchronous communication, which transmits data in a continuous stream without start and stop bits, asynchronous communication is more flexible and can handle variations in timing between the sender and receiver.

    What network topology consists of a single central cable to which all computers and other devices connect?

    • Star

    • Bus

    • Ring

    • Mesh

    Correct Answer
    A. Bus
    Explanation
    A network topology that consists of a single central cable to which all computers and other devices connect is known as a Bus topology. In this type of network, all devices share the same communication medium, which is the central cable. Each device is connected to the cable through a connector called a tap. When a device wants to communicate with another device, it sends the data onto the bus, and all devices on the network receive the data. This topology is simple and cost-effective, but it can be prone to collisions and network congestion.

    • 2

    • 4

    • 6

    • 8

    Correct Answer
    A. 4
    Explanation
    The standard Internet Protocol is broken down into 4 octets. An octet is a unit of digital information that consists of 8 bits. In the case of the Internet Protocol, each octet represents a portion of the IP address. The IP address is made up of four sets of numbers, with each set ranging from 0 to 255. Each set of numbers is represented by one octet, resulting in a total of 4 octets for the complete IP address. Therefore, the correct answer is 4.
