CIW Foundations - Networking Fundamentals - Introduction To Networking

A server specifically provides services and resources for other computers on a network. It acts as a central hub, managing and distributing resources such as files, data, and applications to clients connected to the network. Clients, on the other hand, are the computers or devices that request and use these services and resources from the server. A host refers to any computer or device connected to a network, while a node is a generic term used to describe any device or point on a network.

A network comprises 2 or more interconnected computers that manage and share resources.

Coaxial cable is an example of transmission media. Transmission media refers to the physical means through which data is transmitted from one device to another. Coaxial cable is a type of cable that consists of a central conductor surrounded by an insulating layer, a metallic shield, and an outer insulating layer. It is commonly used for transmitting signals in telecommunications and computer networks.

TCP/IP is an example of a protocol suite. A protocol suite refers to a set of protocols that work together to enable communication between devices on a network. TCP/IP, which stands for Transmission Control Protocol/Internet Protocol, is a widely used protocol suite that provides the foundation for communication on the internet. It includes protocols such as TCP, which ensures reliable delivery of data, and IP, which handles the addressing and routing of data packets. TCP/IP allows different devices and networks to communicate and exchange data seamlessly.

A client requests information from a server.

Transmission media refers to the physical means of connecting devices in a network. It includes various types of cables, such as Ethernet cables, fiber optic cables, and wireless connections like Wi-Fi. Transmission media is responsible for carrying data signals between devices and plays a crucial role in determining the speed, reliability, and distance of network connections. Network services, protocols, and rules are not directly related to the physical means of connection, making transmission media the correct answer.

Multiple Local Area Networks (LAN's) can be joined together to create Wide Area Networks (WAN's). This is done through the use of networking devices such as routers and switches, which connect the LAN's and allow them to communicate with each other over a larger geographical area. WAN's are typically used to connect LAN's in different locations, such as offices in different cities or countries. Therefore, the statement that multiple LAN's cannot be joined together to create WAN's is false.

The statement is true because the peer-to-peer model, where each device on the network can act as both a client and a server, is most effective in small networks with a limited number of users. In larger networks, the peer-to-peer model can become inefficient and difficult to manage, making it more suitable for networks with 10 users or less.

In the server-based model, the host on the network can either function as a client or a server, but not both simultaneously. This means that the host can either request services from other servers or provide services to other clients, but it cannot perform both functions at the same time. Therefore, the statement "True" is correct.

The 2-tier relationship best describes the Client/Server network model. In this model, there are two main components: the client, which requests services or resources, and the server, which provides those services or resources. The client initiates the request and the server responds accordingly. This model is characterized by a direct interaction between the client and server, without any intermediate layers or additional tiers.

When the mainframe in a mainframe network goes down, it is referred to as the "Point of Failure." This term is used to indicate the specific location or component in the network where the failure occurred. It helps in identifying and troubleshooting the issue, as well as implementing measures to prevent similar failures in the future.

A host is another name for any device connected to a network. It refers to computers, servers, or any other device that can send or receive data over a network. The term "host" is often used to describe the central device that provides services or resources to other devices on the network. In contrast, a node refers to any point or junction in a network where data is transmitted or received. Therefore, the correct answer is "Host."

The 1st tier in the Client/Server architecture is made up of the client. In this architecture, the client is responsible for making requests to the server and receiving responses. The client sends requests for data or services to the server, which then processes these requests and sends back the requested information. The client is typically a user interface or application that interacts with the user and acts as an intermediary between the user and the server.

The correct answer is "Scalable" because client/server architectures can be easily expanded or scaled up to accommodate a growing number of users or increased workload. This means that as the demand for resources or services increases, the network can handle the additional load without significant performance degradation or the need for extensive reconfiguration or redesign.

A web server is typically positioned in tier 2 of a client/server network. Tier 2 is responsible for processing requests from clients and retrieving the necessary data from tier 3, which consists of databases and other data storage systems. The web server acts as an intermediary between the client and the data, handling the processing and delivering the requested information to the client.

Peer-to-peer networking allows users to share resources directly with each other without the need for a centralized server. It offers several benefits such as a choice of resources, cost-effectiveness, and user-friendliness. However, the given answer states that a high level of technical skill is not required to implement peer-to-peer networking, which is incorrect. In reality, setting up and managing a peer-to-peer network does require a certain level of technical expertise and knowledge.

Distributed processing is when processing is carried out using different client computers or applications.

Peer-to-peer network models create difficulties with file management because in a peer-to-peer network, there is no centralized server to manage and control file access and sharing. Each device in the network has equal rights and responsibilities, which can lead to issues such as lack of coordination, difficulty in tracking file versions, and potential security risks. Therefore, it is true that peer-to-peer network models create difficulties with file management.

Network services refer to the combination of hardware and software capabilities that need to be shared between devices on a network. These services include functions such as file sharing, printing, email, and remote access. They enable devices to communicate and collaborate effectively on a network, allowing users to access shared resources and services. Therefore, network services are the correct answer in this context.

In a Client/Server network, a computer server is responsible for managing resources, data, and services for the connected clients. It is the backbone of the network, handling requests from clients and providing them with the necessary information or functionality. Therefore, it is referred to as the "back-end" of the network, as it operates behind the scenes, supporting the front-end operations and ensuring smooth communication and data management within the network.

Peer-to-peer networking provides the advantage of cost savings. In this type of network, there is no need for a central server, which eliminates the need for expensive hardware and maintenance costs. Instead, each device can act as both a client and a server, sharing resources and distributing the workload. This decentralized approach reduces the overall cost of setting up and maintaining the network, making it a cost-effective solution for small-scale environments.

A peer-to-peer network structure tends to be implemented in small networks. In this type of environment, all computers are considered equal and can act as both clients and servers. Each computer can share resources and files with other computers on the network without the need for a dedicated server. This decentralized approach is suitable for small networks with fewer computers and less complex networking needs.

MS Server 1998 does not have peer-to-peer networking in mind. This is because MS Server 1998 is a server operating system specifically designed for network environments, focusing on client-server architecture rather than peer-to-peer networking. It is intended for use in enterprise settings where centralized management and control are required, making it less suitable for peer-to-peer networking.

A database server is the correct answer because it serves as the third tier in a 3-tier client/server network architecture. In a 2-tier architecture, the client directly communicates with the server to retrieve data. However, by introducing a database server, the client communicates with the application server, which in turn communicates with the database server to retrieve and store data. This separation of responsibilities allows for better scalability, security, and performance in the network architecture.

Collaborative networks refer to the type of networks that facilitate collaboration and communication among individuals or groups. Web-based networks are a type of collaborative network that operate over the internet and allow users to connect, share information, and collaborate online. This type of network is commonly used for social media platforms, online forums, and other web-based applications that enable users to interact and collaborate remotely. Therefore, the correct answer is "Web-based Networks."

The correct answer is Peer-to-Peer and Server-based. This is because an enterprise network typically combines the features of both peer-to-peer and server-based models. In a peer-to-peer network, all devices have equal capabilities and can act as both clients and servers, allowing for easy sharing of resources. On the other hand, a server-based network relies on a central server that stores and manages resources, providing centralized control and security. By combining these two models, an enterprise network can benefit from the flexibility and ease of sharing in a peer-to-peer network, as well as the centralized control and security offered by a server-based network.
