CSEC: Data Communications And Networks Quiz!

If you studied, you would know that there are client server networks and peer-to-peer networks the first of which has a LARGER CAPACITY dedicated server to store the files centrally.

Local area networks (LANs) are capable of covering a variety of areas, including a single campus, a single house, a single department, and a single office building. This means that LANs have the capacity to provide network connectivity and communication within these different environments. Therefore, the correct answer is "All of the above."

Intranets are internal networks within an organization that function similarly to the Internet but are protected by firewalls and other security measures to control access and ensure data security within the organization. Firewalls are typically used to manage and secure both intranets and the broader Internet, ensuring that only authorized users can access specific resources while preventing unauthorized access from external networks. Therefore, both intranets and the Internet can be protected by firewalls to maintain security.

Remember that the NIC is visible only by the (squarish-shaped) port that connects the cable to the network

While the other options describe aspects of networks, such as the devices working together, computers linked together, or a combination of laptops and desktops connected wirelessly, the essence of a network lies in the interconnection of computers to facilitate resource sharing and communication.

Using a local area network (LAN) provides the advantage of being able to share all the resources with others. This means that files, printers, and other devices can be easily accessed and used by multiple users on the network. This promotes collaboration and efficiency as it eliminates the need for each individual to have their own separate resources. Additionally, sharing resources on a LAN can also lead to cost savings as it reduces the need for duplicate equipment and allows for centralized management and maintenance.

The correct answer is Twisted Pair Cable. This type of cable consists of two copper wires twisted together, without any aluminum mesh protection. It is considered the simplest wired transmission cable because of its basic construction.

Communication within the computer, moderated by the processor, is synchronous, happening in regular intervals. In synchronous communication, the sender and receiver are synchronized and operate at the same clock rate. This means that data is transmitted in a consistent and predictable manner, with both parties waiting for each other to complete a task before proceeding. This type of communication is commonly used in systems where timing and coordination are crucial, such as in real-time applications or when multiple devices need to be synchronized.

The devices that use bluetooth operate within the same frequencies.

Each of the nodes in a network connect through a device called a modem, network interface card (NIC), or NIC so that they can access shared resources. Both modems and network interface cards are commonly used to connect devices to a network. Modems are used to connect devices to the internet, while network interface cards are used to connect devices to a local area network (LAN). Both devices enable communication between nodes and allow them to access shared resources on the network.

BROADBAND has come to be the term for any kind of network connection that can send hundreds of thousands of bits per second.

This is a technology for transmitting digital and analog signals between two locations on a line of sight radio path, meaning the wireless link between two twoers (transmitter and receiver) within a visible, unobstructed, straight line distance of eath other.

The intranet is smaller that the Internet in physical size and scope, therefore it must be less expensive. It is defined as secure because of its use of a firewall to protect its users and the user data.

Fibre Optic Cables send data not by electricity, but by light. The cables use pulses of light to transmit information over long distances. The light signals are generated by lasers, which convert electrical signals into light signals. These light signals travel through the fibre optic cables, which are made of thin strands of glass or plastic. The light signals bounce off the walls of the cables, allowing them to travel long distances without losing much of their strength. At the receiving end, the light signals are converted back into electrical signals for the data to be processed.
