Study Notes
Client/Server Architecture
- Client/server architecture involves two primary components: clients and servers.
- Clients are devices (e.g., computers, smartphones, tablets) that request services from servers.
- Servers provide services to clients, such as data storage, application execution, and resource sharing.
- Clients communicate with servers over a network, typically using protocols like TCP/IP.
Network Hardware
- Network hardware facilitates communication between devices on a network.
-
Wired Network Hardware
- Ethernet Cables: Transmit data between devices using physical connections.
- Network Interface Cards (NICs): Connect devices to a network and process data transmissions.
- Hubs: Simple devices that broadcast data to all connected devices.
- Switches: Forward data based on destination addresses, improving network performance.
- Routers: Connect multiple networks and direct traffic between them.
-
Wireless Network Hardware
- Wireless Access Points (WAPs): Provide wireless network connectivity to devices.
- Wireless Routers: Combine routing functionality with wireless access point capabilities.
- Wireless Network Cards: Connect devices to wireless networks.
Scenario-Based Considerations
- Hybrid IT Infrastructure: Combining on-premises resources with cloud-based services.
- Scalability and Flexibility: The ability to easily expand or adapt the infrastructure to meet changing demands.
- Security: Implementing measures to protect data, applications, and devices from unauthorized access.
- Performance Optimization: Achieving efficient data transfer and processing speeds.
- Cost Management: Balancing infrastructure investments with operational costs.
Client/Server Architecture
- Client devices: User interface, access to resources. Examples: desktops, laptops, tablets, smartphones.
- Server devices: Provide resources and services to clients. Examples: web servers, databases, file servers, email servers.
- Interaction: Clients request resources from servers, servers respond with data or services.
-
Types of Servers:
- Physical Servers: Standalone, occupy physical space.
- Virtual Servers: Software-based, run on physical servers, allowing for efficient resource utilization.
- Cloud Servers: Hosted on remote data centers, pay-as-you-go, scalable, accessible from anywhere.
Network Hardware
- Network Interface Card (NIC): Enables devices to connect to a network, transforms data for transmission.
- Network Cables: Connect devices and network components. Examples: Ethernet cables (wired), fiber optic cables (high-speed).
- Network Switches: Connect multiple devices on a network, manage traffic flow, forward data packets efficiently.
- Network Routers: Connect different networks, direct traffic between networks, manage data forwarding based on routing tables.
- Wireless Access Point (WAP): Creates a wireless network, transmits data using radio waves, allowing devices to connect without cables.
- Firewall: Security device that filters incoming and outgoing network traffic, preventing unauthorized access.
Scenario-Based Questions
-
A company needs to connect its office building to a remote branch office. What network hardware is needed?
- A router
- A switch
- A wireless access point
- All of the above
-
Which type of server would be most suitable for a small business with limited budget and IT staff?
- Physical server
- Virtual server
- Cloud server
- None of the above
