Study Notes

Small Office Network Topology

For a small office with less than 10 computers, a star topology is the most suitable.

Hybrid Topology Disadvantage

A primary disadvantage of a hybrid topology is the increased complexity in managing and troubleshooting the network due to the combination of different topologies.

Client-Server Network Characteristic

A client-server network is characterized by a central server that manages resources and provides services to multiple client computers.

Star Topology Cable Type

The cable type most commonly utilized in star topologies is unshielded twisted pair (UTP) cable.

Mesh Topology Node Connections

A mesh topology relies on direct connections between all nodes, creating redundant paths for data transmission.

Network Design Primary Focus

The primary focus of network design is efficiency and scalability.

Linear Bus Network Drawback

A common drawback of the linear bus network topology is its single point of failure. If the bus cable fails, the entire network is disrupted.

Equal Authority Network Design

A peer-to-peer network design allows all nodes to have equal authority, meaning each device can share resources and communicate directly with others.

Star Topology LAN Advantage

A key advantage of using a star topology in a Local Area Network (LAN) is its centralized management.

Client-Server Network Model Characteristic

A characteristic that is NOT part of the Client-Server network model is the ability for all devices to have equal authority.

Bus Topology Disadvantage

A bus topology has the disadvantage of being susceptible to collisions. If two devices transmit data simultaneously, the data can collide and become corrupted.

Hybrid Topology Advantage

The main advantage of combining different topologies in a hybrid topology is increased flexibility and scalability.

Personal Area Network (PAN) Definition

A Personal Area Network (PAN) is defined as a network that connects devices within a small personal space, such as a home or office.

Mesh Topology Benefit Scenario

A Mesh topology is most beneficial in scenarios where high reliability and redundancy are critical, such as in a military network or a building with multiple floors.

Star Topology Essential Component

An essential component for connecting devices in a star topology is a central hub or switch.

Network Interface Card (NIC) Function

The primary function of a Network Interface Card (NIC) is to provide a physical connection between a computer and a network.

Transceiver Function

In a wireless communication system, the primary purpose of a transceiver is to send and receive radio signals.

Secure Data Transfer Protocol

The protocol most commonly used for securely transferring sensitive information over the internet is Transport Layer Security (TLS).

Intranet vs. Extranet

The main difference between an intranet and an extranet is that an intranet is a private network used within an organization, while an extranet extends the intranet to external partners or customers.

Network Traffic Analysis Technology

The security technology that analyzes incoming and outgoing network traffic to protect an organization's network is called a firewall.

VPN Function

A virtual private network (VPN) provides a secure and encrypted connection over a public network, such as the internet.

Network Protocol Statement

A network protocol defines the rules and procedures for communication between devices on a network.

Firewall Role in Security

A firewall plays a critical role in network security by acting as a barrier between a private network and the public internet, blocking unauthorized access.

Microwave Transmission Disadvantage

A disadvantage of using microwave signals for data transmission is that they can be affected by weather conditions such as rain, snow, and fog.
