A network consists of two or more computers that are linked in order to share resources (such as printers and CDs), exchange files, and allow electronic communications.
Network Interface Cards. The network interface card (NIC) provides the physical connection between the network and the computer workstation. Most NICs are internal, and they are included in the purchase of most computers.

What is network topology and types?
Network topology refers to the geometric arrangement of links and nodes in a computing network. Alternately, network topology may describe how the data is transferred between these nodes. There are two types of network topologies: physical and logical.
What is physical topology?
Physical topology refers to the interconnected structure of a local area network (LAN). The method employed to connect the physical devices on the network with the cables, and the type of cabling used, all constitute the physical topology.
What do you mean by topology?
A network topology is the physical and logical arrangement of nodes and connections in a network. Nodes usually include devices such as switches, routers and software with switch and router features. Network topologies are often represented as a graph.
What is the meaning of network topology?
Network topology describes the physical and logical relationship of nodes in a network, the schematic arrangement of the links and nodes, or some hybrid combination thereof.
What is network topology mapping?
Network topology mapping is the practice of graphing a communication network’s topology and representing all its nodes and links. This is easily achieved using network topology software.
What are the 2 types of threats?
Types of Threats Threats can be classified into four different categories; direct, indirect, veiled, conditional.
Which of the following is a type of action that has the potential to cause harm?
A hazard is any source of potential damage, harm or adverse health effects on something or someone. Basically, a hazard is the potential for harm or an adverse effect (for example, to people as health effects, to organizations as property or equipment losses, or to the environment).

- Information Security.
- Network Security.
- Endpoint Security.
- Internet Security.
What is a peer to peer network quizlet?
What is peer to peer networks? A peer-to-peer (P2P) network is created when two or more PCs are connected and share resources without going through a separate server computer.
What is a client-server network?
A client-server network is a communications model in which multiple client programs share the services of a common server program.
What is network topology quizlet?
Network Topology. This is the shape or physical layout of the network. This is how the computer and other devices are linked together to form a network.

What are physical connections?
Physical connection means the number of trunk lines or complete circuits and connections, including connections by wire, optics, radio signal or other means, required to furnish reasonably adequate telecommunications service between telecommunica- tions providers.
What is the physical structure of computer?
The physical structure of a computer is called hardware. Examples of computer hardware are Motherboard, RAM, CPU, Mouse, Keyboard, CD, DVD, hard disk etc.
What are the 3 types of connection?
Lesson Plans. Based on the Guided Comprehension Model by Maureen McLaughlin and Mary Beth Allen, this lesson helps students learn three types of connections (text-to-text, text-to-self, and text-to-world) using a double-entry journal.
What are the types of physical media?
Examples of physical media include twisted-pair copper wire, coaxial cable, multimode fiber optic cable, terrestrial radio spectrum and satellite radio spectrum. Physical media fall into two categories: guided media and unguided media.
What are the 3 main network topologies?
Three of the main topologies include bus, star and ring.
Why network topology is used?
Simply put, network topology helps us understand two crucial things. It allows us to understand the different elements of our network and where they connect. Two, it shows us how they interact and what we can expect from their performance.
