Computer Systems and Networks Quiz

Computer Basics, Types of Client Computing Systems, Servers, and Components of a Computer Network

Computer Basics:

• A computer is an electronic device that can perform a variety of tasks, like processing data, storing information, and communicating with other devices.
• A computer is made up of hardware and software components.
• Hardware refers to the physical components of a computer, such as the CPU, memory, storage devices, input devices, output devices, and other peripherals.
• Software refers to the programs, applications, and operating system that run on the computer.
• The CPU processes instructions and data, the RAM provides temporary storage, and the storage devices provide long-term storage.
• Input devices allow users to interact with the computer, while output devices display information.
• Peripherals can provide additional functionality.

Types of Client Computing Systems:

• Desktop computers are traditional computers that sit on a desk and typically consist of a tower or all-in-one unit that includes a monitor.
• Laptops are portable computers that include a built-in screen and keyboard, making them ideal for use on the go.
• Tablets are lightweight devices with touchscreens that can be used for browsing the web, reading books, watching videos, and other tasks.
• Smartphones are mobile devices that include a touchscreen, camera, and phone capabilities.
• Thin clients are stripped-down computers that rely on a network connection to access applications and data that are stored on servers.
• Workstations are specialized computers designed for demanding applications such as video editing, 3D modeling, and scientific simulations.

Servers:

• A server is a computer system or software application that provides functionality or services to other computers or devices on a network.
• Servers can take many forms and serve different purposes, including web servers, file servers, application servers, database servers, and email servers.
• Servers typically have higher processing power, storage capacity, and network bandwidth than client computers, and may be optimized for specific tasks or types of workloads.

Components of a Computer Network:

• Network Interface Card (NIC) connects a computer to a network.
• Router connects multiple networks together, such as a LAN and the internet.
• Switch connects multiple devices within a network, such as computers, printers, and servers.
• Firewall helps protect a network from unauthorized access or attacks.
• Modem connects a network to the internet, typically through a telephone line, cable line, or satellite connection.
• Access Point allows wireless devices to connect to a wired network.
