Study Notes

Server Overview

A server is a specialized computer or software that provides services, resources, or data to client computers over a network.
Servers are essential in both local networks and the internet for effectively managing network resources.

Definition and Purpose

A server manages network resources and offers services like file storage, application access, and internet connectivity.
Operates in a centralized way for efficient resource management.

Types of Servers

File Server: Stores and allows access to files, supporting file sharing across the network.
Web Server: Hosts websites and delivers content to browsers via HTTP/HTTPS (e.g., Apache, Nginx).
Database Server: Manages databases and provides access to stored data (e.g., Microsoft SQL Server, MySQL).
Mail Server: Sends, receives, and stores email (e.g., Microsoft Exchange, Postfix).
Application Server: Delivers application services to clients (e.g., Tomcat, JBoss).
DNS Server: Resolves domain names to IP addresses, facilitating web access.
FTP Server: Manages file transfers using the File Transfer Protocol, enabling uploads and downloads.

Key Characteristics

Network Role: Servers manage resources and fulfill requests from multiple clients simultaneously.
High Availability: Designed for reliability, often equipped with redundant components for uptime.
Performance: Typically has more powerful hardware to handle multiple clients and heavy workloads.
Scalability: Can be upgraded or expanded to accommodate more users or higher demands.

How Servers Work

Operates on the client-server model where servers provide resources and clients request them.
Processes client requests and sends back appropriate responses, like delivering a requested file.

Server Operating Systems

Windows Server: A tailored version of Windows for managing network resources and security.
Linux Server Distributions: Linux variants like Ubuntu Server, CentOS, and Red Hat Enterprise Linux, known for stability and flexibility.

Physical vs. Virtual Servers

Physical Server: A dedicated hardware unit located in a data center or server room.
Virtual Server: A virtual instance created through virtualization, allowing efficient resource use while operating on physical hardware.

Examples of Server Usage

Corporate Networks: File servers allow shared access to documents.
Web Hosting: Web servers handle website hosting and traffic.
Cloud Services: Utilize servers for scalable resources available on-demand over the internet.

Client Overview

A client is a device or software that requests and utilizes services or resources from a server over a network, forming the basis of the client-server model.

Definition and Role

Clients initiate requests for services, relying on servers for the requested resources or data.

Types of Clients

Hardware Clients: Physical devices like personal computers, mobile devices, and thin clients that connect to networks.
Software Clients: Applications such as web browsers, email clients, FTP clients, and chat applications that interact with servers to access services.

How Clients Work

Operate on a request-response model; clients send requests to servers, which process and respond.
Utilize network protocols like HTTP, FTP, or SMTP for communication.

Characteristics of Clients

User Interface: Clients have interfaces that facilitate user interaction with applications.
Dependence on Servers: Clients rely on servers for resource provision and do not typically host resources.
Client Software: Requires specific applications, like browsers for web access or email clients for email retrieval.

Client-Server Model

Client-server architecture allows clients to initiate communication by making requests while servers handle responses.
Supports scalability, as servers manage requests from multiple clients effectively.

Examples of Client Applications

Web Browsers: Request and display web content from servers.
Email Applications: Connect to servers to manage emails.
Media Players: Stream audio and video from dedicated media servers.
Online Games: Connect to servers for multiplayer gaming experiences.

Client Types in Network Architecture

Fat Clients: Clients that handle significant processing tasks independently of servers.
Thin Clients: Rely on servers for most processing, typically found in virtual desktop setups.
