BTE-210 Final Exam/revision guide exam questions and answersBTE-210 Final Exam/revision guide exam questions and answers processor (CPU) - correct answers-Manipulates the data and controls the tasks performed by the other components. Primary Storage - correct answers-Temporarily stores data and program instructions during processing. Secondary Storage - correct answers-Stores data and programs for future use. Input Technologies - correct answers-Accept data and instructions and convert them to a form that the computer can understand. Output Technologies - correct answers-Present data and information in a form people can understand. Communication Technologies - correct answers-Provide for the flow of data from external computer networks (e.g., the Internet and intranets) to the CPU, and from the CPU to computer networks. Making Sense of Data Measures - correct answers-1 BIT is the smallest unit of data in a computer. • Can be either 1 or 0 8 bits= 1 byte (enough for a single letter or symbol) Kilobytes (KB) - correct answers-like a small snippet of text. Imagine a short text message you send on your phone. That message, along with a few emojis, might take up around 1 kilobyte of data. Megabytes (MB) - correct answers-like a photo you take with your smartphone. A typical photo might be around 2-4 megabytes in size. So, think of your last vacation picture—that's a few megabytes of data. Gigabytes (GB) - correct answers-like a full-length movie you stream online. Streaming a movie in high-definition can use up around 1.5 to 2.5 gigabytes of data. When you're watching your favorite shows, you're dealing with gigabytes.

Cache memory is physically located closer to the CPU than RAM. Random Access Memory (RAM) - correct answers-Part of primary storage that holds a software program and small amounts of data for processing. Read-Only Memory (ROM) - correct answers-Type of chip where certain critical instructions are safeguarded. ROM is nonvolatile, so it retains these instructions when the power to the computer is turned off. Computer Memory - Secondary Storage - correct answers-Non-volatile memory that provides long-term storage for data, even when the computer is powered off. This is where your files, applications, and the operating system are stored Type of Computer Memory- Secondary Storage - correct answers-• Magnetic Tape • Magnetic Discs • Solid State Drives (SSD) • Optical Storage Devices • Flash Memory Solid-State Drives (SSDs) - correct answers-Data storage devices that serve the same purpose as a hard drive and store data in memory chips. Whereas hard drives have moving parts, SSDs do not. Flash Memory Devices (or memory cards) - correct answers-Nonvolatile electronic storage devices that contain no moving parts and use 30 times less battery power than hard drives. Flash devices are also smaller and more durable than hard drives. One popular flash memory device is the thumb drive (also called memory stick, jump drive, or flash drive). extra info - correct answers-Traditional hard drives are less expensive Solid-state drives are faster and are more reliable Optical Drives - correct answers-Optical drives played a vital role in distributing content before digital downloads and streaming became dominant. • With the rise of USB drives, o
