Network Fundamentals and Concepts

What is the primary purpose of a network?

• To connect devices for sharing data and resources.

• To provide a single internet connection for one device.

• To store all digital information in one central location.

• To physically secure devices from unauthorized access.

In a wired network, what device typically connects multiple end devices like computers and printers?

• A router

• A modem

• A switch

• A firewall

Which of the following best describes Wi-Fi?

• A type of wired connection for high-speed data transfer.

• A method for connecting devices wirelessly to a network.

• A security standard for encrypting network traffic.

• A device that translates network addresses.

What is a "protocol" in the context of computer networking?

• A physical cable used to connect devices.

• A set of rules that devices follow to communicate and handle data.

• A type of software that protects against viruses.

• A unique identifier assigned to each network device.

Which of the following are considered nodes in a network?

• Workstations, servers, and printers

• Switches, routers, and cables

• Modems, firewalls, and antivirus software

• Operating systems, applications, and user accounts

Which statement accurately describes a Small Office/Home Office (SOHO) network?

• It typically connects a few devices like computers, printers, and phones.

• It spans across multiple buildings or geographical locations.

• It primarily uses hubs for central connectivity.

• It is designed for large corporations with thousands of users.

What characterizes an enterprise network?

• It is typically a small network with only a few devices.

• It covers a large geographical area, potentially multiple buildings or cities.

• It is primarily used for home office setups.

• It connects devices within a single room.

What is the primary difference between a Local Area Network (LAN) and a Wide Area Network (WAN)?

• LANs connect devices wirelessly, while WANs use wired connections.

• LANs are networks in a local area like a single building, while WANs connect networks that are geographically separated.

• WANs are typically smaller than LANs in terms of the number of connected devices.

• LANs are used by service providers, while WANs are used by individual companies.

Which device is commonly used to provide wireless connectivity in a home or office network?

• Printer

• Firewall

• Access Point

• Switch

What does the term 'bandwidth' refer to in computer networking?

• The number of devices connected to a network

• The security level of a network

• The amount of data that can be transmitted over a network in a given time

• The physical size of a network cable
