| Front | Back |
| Compare and contrast common units of measure. | Storage: Bit, Byte, KB, MB, GB, TB. Throughput: bps, Kbps, Mbps. Speed: MHz, GHz. |
| Define 'bit' and 'byte'. | A bit is 0 or 1; a byte is 8 bits. |
| Define a switch in networking. | Connects devices within a network, forwards data to destinations. |
| Define a virtual machine. | Software-based computer emulation running OS and apps. |
| Define a VPN. | A service that encrypts your internet connection and hides your online activity. |
| Define IaaS. | Provides virtualized computing resources over the internet. |
| Define RAM. | Memory used for storing data and machine code in use. Stands for Random Access Memory. |
| Explain a wireless access point. | Allows Wi-Fi devices to connect to a wired network. |
| Explain SaaS. | Software delivered over the internet on a subscription basis. |
| Explain the basics of computing. | Input, Processing, Output, Storage. |
| Explain the troubleshooting methodology. | 1. Identify problem 2. Establish theory 3. Test 4. Plan solution 5. Verify 6. Document. |
| Explain what a data center is. | A facility housing computer systems and storage components. |
| Explain what a motherboard is. | Main PCB in a computer connecting CPU, RAM, and storage. |
| Explain what DNS is. | Translates domain names into IP addresses. |
| Identify notational systems. | Binary, Hexadecimal, Decimal, Octal. |
| What are the functions of input, processing, output, and storage? | Input: enter data; Processing: manipulate; Output: display; Storage: save. |
| What is a CPU? | Performs most of the processing inside a computer. Stands for Central Processing Unit. |
| What is a firewall? | Monitors and controls network traffic based on security rules. |
| What is a hard drive? | Storage device using rotating disks to store data. |
| What is a modem? | Converts data between digital and analog for transmission. |
| What is a router? | Forwards data packets between networks\, directs internet traffic. |
| What is an IP address? | Unique identifier for devices on a network. |
| What is cloud computing? | Delivery of services like storage and software over the internet. |
| What is network segmentation? | Dividing a network into smaller parts for better security and performance. |
| What is PaaS? | Platform for developing, running, and managing applications. |
| What is the difference between binary and hexadecimal notation? | Binary: base 2 (0,1), Hexadecimal: base 16 (0-9, A-F). |
| What is virtualization? | Creating a virtual version of hardware or network resources. |
About the Flashcards
Flashcards for the CompTIA Tech+ exam reinforce the building blocks of information technology, from binary and hexadecimal notation to the role of bits, bytes, and larger storage-throughput units. Students revisit the core input-process-output-storage model and identify essential hardware such as CPU, RAM, hard drives, and motherboards.
The deck also surveys networking and cloud foundations tested on the exam, including switches, routers, firewalls, VPNs, DNS, IP addressing, and principles of network segmentation. Learners practice definitions of virtual machines, SaaS, PaaS, IaaS, and broader cloud computing, while a step-by-step troubleshooting methodology and data-center concepts round out the key knowledge areas.
Topics covered in this flashcard deck:
- Number systems & data units
- Computing model & hardware
- Networking devices & protocols
- Cloud & virtualization models
- Security and troubleshooting
