ITA study guide
ITA · Work through your exam, one topic at a time.
The Information Technology Associate (ITA) is an entry-level credential for people who want to demonstrate a broad, practical grounding in IT rather than deep specialization in one area. It suits career changers, help-desk and desktop-support staff, students finishing a first IT program, and anyone in an adjacent role who needs to speak credibly with technical colleagues. The ITA study guide has 8 sections and about 2,145 words.
01IT Fundamentals and Computer Hardware
A candidate must be able to name the major internal components and explain what each does: CPU (cores, clock speed, cache levels), RAM (volatile working memory), storage (HDD vs SSD, NVMe, SATA), motherboard and chipset, PSU, and expansion buses (PCIe). Understand the boot sequence: firmware (BIOS/UEFI) performs POST, then locates a boot device and hands control to the bootloader.
319 words, about 2 min02Operating Systems and Software
Understand the OS as a resource manager: process and thread scheduling, memory management (virtual memory, paging), file systems (NTFS, ext4, APFS), device drivers, and the user/kernel boundary. Know the difference between 32-bit and 64-bit addressing and its memory limits.
296 words, about 1 min03Networking and Connectivity
Know the OSI and TCP/IP models and map protocols to layers: Ethernet at the link layer, IP at the network layer, TCP/UDP at transport, HTTP/DNS/DHCP at application. Understand IPv4 addressing, subnet masks, default gateways, private ranges (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16), NAT, and basic IPv6.
274 words, about 1 min04Security and Data Protection
Understand the CIA triad (confidentiality, integrity, availability) and apply it to controls. Know authentication factors (something you know, have, are), MFA, and password policy.
259 words, about 1 min05Troubleshooting and Support
Learn a structured method: identify the problem, establish a theory, test the theory, plan and implement a fix, verify full functionality, and document. Know how to gather symptoms through questioning, check logs (Event Viewer, syslog), and use tools like ping, ipconfig/ifconfig, tracert, nslookup, and resource monitors.
261 words, about 1 min06Databases and Data Management
Understand relational concepts: tables, rows, columns, primary and foreign keys, and normalization to reduce redundancy. Know basic SQL: SELECT, INSERT, UPDATE, DELETE, WHERE, JOIN, GROUP BY, and aggregate functions.
242 words, about 1 min07Web Technologies and Application Development
Understand the client-server model and the request-response cycle over HTTP/HTTPS. Know front-end basics (HTML structure, CSS styling, JavaScript behavior) and back-end concepts (server logic, APIs, databases).
251 words, about 1 min08IT Service Management and Professional Practices
Understand core ITIL-style concepts: incidents (unplanned interruptions), service requests (standard user needs), problems (root cause of recurring incidents), and changes (modifications under control). Know the service desk role, priority as impact times urgency, SLA targets, and the difference between incident and problem management.
