The Atanasoff-Berry Computer (ABC) is considered an electro-mechanical computer due to its use of both electrical and mechanical components for computation. Here’s why:
1. Electrical Components: The ABC made use of vacuum tubes for digital computation, making it one of the earliest electronic computing devices. Vacuum tubes were used to perform logical operations and store data. This electronic aspect is a fundamental part of what makes a computer like the ABC distinct from purely mechanical computing machines of earlier eras.
2. Mechanical Components: In addition to its electronic aspects, the ABC utilized mechanical components for input and output processing. It used punched cards (a mechanical storage medium) for input and output, and it also had mechanical rotating drums to store electrical charges (as memory) for the purposes of computing. These rotating drums represent a blend of mechanical engineering and electrical storage principles, which marked a transitional phase in the evolution of computing technology from purely mechanical to electronic systems.
The combination of these electrical and mechanical elements in the ABC’s design is why it’s often referred to as an electro-mechanical computer. This hybrid approach was innovative at the time, laying groundwork for future developments toward fully electronic computers.

In a network where the communication channel is shared by all the machines, this typically refers to a broadcast network architecture. In such networks, when a machine sends a message, the communication channel carries that message to all machines on the network. Each machine receives the message but processes it only if the message is addressed to it. This shared communication model is fundamental to several types of networks, including:
1. Ethernet networks: Traditional Ethernet networks use a bus topology where all computers are connected to a single communication line or a coaxial cable. In this scenario, data packets sent by any computer are broadcast to and can be received by all other computers on the network, but only the intended recipient processes the message further.
2. Wireless Local Area Networks (WLANs), such as Wi-Fi: In a WLAN, all wireless devices within the same broadcast domain (usually defined by the range of the wireless access point) share the same communication medium (airwaves). When a device transmits data, all other devices within the network can receive the data, but similar to the Ethernet model, only the intended recipient processes the data.
3. Token Ring networks (largely historical): In a Token Ring network, the communication channel is shared in a slightly different sense. A token circulates around the ring, and a machine can send a message only when it has the token. Although not a broadcast mechanism in the strictest sense, the ring topology inherently shares the channel among all

In a network where the communication channel is shared by all the machines, it is typically referred to as a broadcast network. In this context, any transmission sent by one machine is capable of being received by all other devices on the network. Ethernet networks in their early forms are classic examples of such environments, utilizing a shared medium (such as a coaxial cable) to facilitate communication. This approach necessitates mechanisms to control access to the shared medium to avoid data collisions and ensure that only one machine transmits at a time. Techniques like Carrier Sense Multiple Access with Collision Detection (CSMA/CD) were developed for this purpose in traditional Ethernet networks.
