CompTIA Tech+ FC0-U71 Prep Hands-on training, Practice Exam

Explain the basics of computing by exploring input, processing, output, and storage, including primary storage (RAM) and secondary storage (hard drives), and key hardware components.

Explore how computers read numbers across notational systems—binary base two, decimal base ten, hexadecimal base sixteen, and octal base eight—along with transistors powering processors and memory addressing.

Decode data measurement from bits to bytes, and from kilobytes to terabytes, while understanding how transfer speeds in bits per second relate to storage in bytes.

Explore common computing devices: smartphones, tablets, e-readers, laptops, workstations, servers, gaming consoles, vr/ar, IoT and home automation, connected cars, ip cameras, streaming devices, medical and fitness tech.

Explore the purpose of common internal components, including the motherboard, bios, ram, cpu, gpu, nic cards, and volatile versus non-volatile storage, from hard drives to nvme, with onboard vs expansion.

Explains how CPU, RAM, and hard drive work together, compares volatile and non-volatile memory, and shows data flow from hard drive to RAM to CPU with bottlenecks.

Identify common peripheral devices such as printers, scanners, keyboards, mice, webcams, and external drives, and learn how plug-and-play and drivers govern their installation, including network printers and manufacturer drivers.

Compare common input/output interfaces, including wired ethernet and fiber, usb types and display ports, wireless options like wifi and bluetooth, and near-field communication.

Explain virtualization and cloud computing basics, including hypervisors, guest operating systems, and IaaS, PaaS, SaaS, plus on premises, cloud, and hybrid deployments.

Compare and contrast common internet service types by highlighting wired options like fiber and cable, and wireless options such as satellite, RF, and cellular, including speed, availability, and symmetry.

Explore basic networking concepts by building a small network with a switch, connecting laptops to share data and printers, and understanding protocols, IP addressing, and ports.

Explore wireless basics, including 802.11 standards and wireless bands (2.4, 5, 6 ghz), interference, attenuation, and how to configure routers via web interfaces to optimize speed and range.

Identify components of an operating system, file systems and file management, including folders, extensions, encryption, compression, and permissions. Explore services, processes, drivers, and graphical user interface versus command line interface.

The operating system acts as the core software that manages hardware, disks, and tasks, while providing a hardware abstraction layer, file systems, backups, and authentication with access control.

Explore the purpose and use of application software, including productivity tools like Word, Excel, and PowerPoint, collaboration and email apps, and web browsing and remote support tools such as TeamViewer.

Configure and optimize your web browser for privacy, security, and productivity by using private browsing, extensions, caching controls, pop-up blockers, profile synchronization, bookmarks, accessibility features, and appearance settings.

Discover artificial intelligence basics, including AI chatbots, AI assistants, and generative AI driven by prompting, with examples like ChatGPT and Copilot, and its use in coding and content development.

Compare and contrast programming language categories, from interpreted and compiled languages to scripting and query languages, using Python and a simple game to illustrate concepts.

Explore basic data types such as char, string, integers, floats, and booleans; understand memory, quotes, concatenation, and true/false logic across languages.

Explore identifiers, variables, constants, and arrays, with naming rules and scope for readable code. Learn functions with parameters and returns, and how objects combine data, behavior, properties, and methods.

Identify programming organization techniques using pseudo code, object oriented concepts, and code comments to plan and structure programs. Explore flowcharts, branching logic, conditional statements, and looping.

Explore the difference between data and information and how data analytics and monetization turn data into a valuable asset for data-driven businesses.

Explore how databases store and organize data with tables, records, fields, and a primary key. Compare flat files and examine storage options from local to cloud for availability and persistence.

Explore relational and non-relational database structures, including schema design, primary and foreign keys, referential integrity, one-to-many relationships, and the differences between structured, semi-structured, and unstructured data.

Learn to back up data with file and system backups, restore procedures, and cloud or local storage strategies to ensure continuity and protect against hardware failure and ransomware.

Explore foundational IT security concepts, including the CIA triad and privacy, and demonstrate authentication, multi-factor authentication, authorization, accounting, and non-repudiation to protect data and people.

Recognize social engineering and phishing; secure devices with authentication, anti-malware, firewalls, and patching. Practice safe browsing with certificate validation and mindful privacy, especially with AI chatbots.

Master password management by enforcing length, complexity, and history policies, using passphrases, and adopting password managers like LastPass and KeePass to prevent reuse and brute-force or dictionary attacks.

Explore encryption fundamentals, including plaintext versus ciphertext, and how encryption safeguards data at rest and in transit across email, HTTPS, VPN, and mobile devices.

Configure strong encryption (WPA2 or WPA3 with a long pre-shared key) and change the SSID and default password to secure your home or small office wireless network.
