Computer Hardware Components Overview

Hardware Components

• Central Processing Unit (CPU):

  • The brain of the computer; processes instructions.
  • Measured in gigahertz (GHz) for speed.

• Memory (RAM):

  • Temporary storage for active processes.
  • More RAM allows for better multitasking and performance.

• Storage Devices:

  • Hard Disk Drive (HDD): Traditional magnetic storage, larger capacity but slower.
  • Solid State Drive (SSD): Faster performance, more durable, but usually more expensive.

• Input Devices:

  • Examples: Keyboard, mouse, scanner, microphone.
  • Used to enter data into a computer system.

• Output Devices:

  • Examples: Monitor, printer, speakers.
  • Used to convey information from the computer.

• Motherboard:

  • Main circuit board that connects all hardware components.
  • Houses CPU, RAM, and provides slots for other components.

• Power Supply Unit (PSU):

  • Converts electrical power to a usable form for the computer's components.

Peopleware Concepts

• User Experience (UX):

  • Focuses on how users interact with software and hardware.
  • Goal is to enhance user satisfaction through usability and accessibility.

• Team Dynamics:

  • How team members communicate and collaborate.
  • Affects productivity and project success.

• Training and Support:

  • Essential for user competence and confidence in using technology.
  • Includes documentation, tutorials, and helpdesk availability.

• Organizational Culture:

  • The values and practices that shape how technology is used within a company.
  • Influences acceptance and adaptation of new technologies.

• Change Management:

  • Strategies to help individuals and organizations adapt to technological changes.
  • Includes communication, training, and involvement of users in the process.

Software Applications

• Operating Systems (OS):

  • Manages hardware and software resources.
  • Examples: Windows, macOS, Linux.

• Productivity Software:

  • Tools that help users perform tasks efficiently.
  • Examples: Microsoft Office, Google Workspace.

• Database Management Systems (DBMS):

  • Software for creating and managing databases.
  • Examples: MySQL, Oracle, Microsoft SQL Server.

• Web Browsers:

  • Applications for accessing the internet.
  • Examples: Chrome, Firefox, Safari.

• Enterprise Software:

  • Solutions that support business processes and operations.
  • Examples: ERP (Enterprise Resource Planning), CRM (Customer Relationship Management).

• Mobile Applications:

  • Software designed for mobile devices.
  • Can be native (built for a specific platform) or cross-platform (compatible with multiple platforms).

• Security Software:

  • Protects computer systems from malware and unauthorized access.
  • Examples: Antivirus software, firewalls, encryption tools.

Hardware Components

• Central Processing Unit (CPU):

  • Acts as the brain of the computer, executing instructions and processes.
  • Performance speed is indicated in gigahertz (GHz).

• Memory (RAM):

  • Provides temporary storage for data that the CPU is actively using.
  • Increased RAM improves multitasking capabilities and overall system performance.

• Storage Devices:

  • Hard Disk Drive (HDD):
    • A traditional magnetic storage option offering large capacity at slower speeds.
  • Solid State Drive (SSD):
    • Offers faster performance and greater durability compared to HDDs, though typically at a higher price.

• Input Devices:

  • Devices like keyboards, mice, scanners, and microphones that allow users to enter data into the computer system.

• Output Devices:

  • Examples include monitors, printers, and speakers, used for conveying information from the computer to the user.

• Motherboard:

  • The main circuit board that interconnects all hardware components, housing the CPU and RAM while providing slots for expansion.

• Power Supply Unit (PSU):

  • Converts electrical power from an outlet into a form usable by the computer's components.

Peopleware Concepts

• User Experience (UX):

  • Focuses on enhancing user satisfaction by improving the interaction between users and technology.
  • Emphasizes usability and accessibility in software and hardware design.

• Team Dynamics:

  • Refers to the communication and collaboration processes among team members, directly impacting productivity and the success of projects.

• Training and Support:

  • Fundamental for enhancing user competency with technology, includes providing documentation, tutorials, and helpdesk assistance.

• Organizational Culture:

  • Encompasses the shared values and practices that influence how technology is utilized within a company, impacting the acceptance of new tech.

• Change Management:

  • Involves strategies for helping organizations and individuals adapt to technological changes, focusing on communication, training, and user involvement.

Software Applications

• Operating Systems (OS):

  • Manages both hardware and software resources within a computer system.
  • Common examples include Windows, macOS, and Linux.

• Productivity Software:

  • Tools designed to assist users in performing tasks efficiently, such as Microsoft Office and Google Workspace.

• Database Management Systems (DBMS):

  • Software used for creating, managing, and manipulating databases; examples include MySQL, Oracle, and Microsoft SQL Server.

• Web Browsers:

  • Applications that enable users to access the internet, with popular options including Chrome, Firefox, and Safari.

• Enterprise Software:

  • Solutions that facilitate business processes, including ERP (Enterprise Resource Planning) and CRM (Customer Relationship Management) systems.

• Mobile Applications:

  • Software specifically designed for mobile devices, which can be either native to a specific platform or cross-platform compatible.

• Security Software:

  • Protects computer systems against malware and unauthorized access, including tools like antivirus software, firewalls, and encryption solutions.
