Foundation Essential Resources IT infrastructure is the It provides the essential foundation of any resources for organizations to organization's technology access, process, and manage operations. It encompasses all information, run applications, the hardware, software, and and connect with users and networking components that customers. enable businesses to function. Enabling O perations It enables organizations to achieve their business goals by facilitating communication, collaboration, data storage, and application execution. Components of IT Infrastructure Hardware Software Networking Data Physical components like Programs and Connections that allow The core of any IT computers, servers, applications that run on devices to communicate infrastructure. Data networking devices, hardware and enable and share resources. This encompasses information storage solutions, and specific tasks, such as includes physical stored, processed, and peripherals. They provide operating systems, infrastructure like cables transmitted within the the foundation for productivity software, and and wireless networks, as system, encompassing a processing, storing, and enterprise applications. well as protocols and wide range of formats and transmitting data. They provide the services that govern data types. instructions that dictate exchange. how hardware functions. Hardware: Computers and Servers Computers and servers are the foundation of an IT infrastructure. They process data, run applications, and store information. Servers are specialized computers designed for high performance and reliability, often handling multiple tasks concurrently. They can be physical machines or virtualized instances. Hardware: Networking Devices Networking devices facilitate communication between computers and other network devices. Routers connect networks and direct traffic between them. Switches connect devices on a local network. Network Interface Cards (NICs): Connect individual computers to a network. Modems: Convert digital data to analog signals for transmission over phone lines. Firewalls: Protect networks from unauthorized access and cyber threats. Hardware: Storag e Solutions Hard Disk Drives (HDDs) Solid-State Drives (SSDs) Cloud Storage Tape Drives HDDs are traditional Cloud storage solutions Tape drives use magnetic storage devices that use SSDs use flash memory to provide off-site storage and tape to store data, offering spinning platters and store data, providing faster access to data over the high capacity and long- magnetic heads to store read/write speeds and internet. They offer term archival capabilities. data. They offer high higher durability compared scalability, accessibility, and They are used for backups, capacity and low cost, to HDDs. They are ideal for cost-effectiveness, making disaster recovery, and long- making them suitable for operating systems, them popular for term data retention. large data backups and applications, and frequently businesses and individuals. archives. accessed data. Operating Systems Windows macOS Linux Android Microsoft Windows is a Developed by Apple, macOS is Linux is a free and open-source Developed by Google, Android popular operating system for a user-friendly operating operating system known for its is a mobile operating system PCs and laptops, known for its system designed for Macs, flexibility, security, and wide powering a majority of user-friendly interface and known for its elegant design range of distributions. smartphones and tablets, wide range of applications. and seamless integration with known for its open-source Apple devices. nature and customizable user experience. Productivity Software Office Suites Project Management These software packages Tools include a range of These tools help with task productivity tools for assignment, scheduling, document creation, collaboration, and tracking spreadsheets, presentations, progress.

This prevents performance issues and downtime. Performance Monitoring Monitoring tools track system performance metrics, such as CPU usage, memory consumption, and network bandwidth. These insights help identify bottlenecks. Security Updates Patching vulnerabilities promptly minimizes the risk of security breaches. Regular updates are crucial to prevent unauthorized access and data theft. System Log s Logs record events and errors that occur within the IT infrastructure. Analyzing logs helps identify potential problems and troubleshoot issues. Backups Regular backups ensure data is protected from accidental loss or hardware failure. Restore points provide a safety net in case of unforeseen events. Disaster Recovery Planning 1 Risk Assessment Identify potential threats and their impact on the IT infrastructure. 2 Backup and Recovery Implement robust backup procedures to restore critical data and systems in case of failure.
