Ergonomic practices for computing aim to enhance user well-being and productivity by optimizing the design and arrangement of workstations. Guidelines include positioning the computer monitor at eye level to reduce neck strain, maintaining a neutral wrist position with the keyboard and mouse, and ensuring a comfortable chair with proper lumbar support. The chair height should allow feet to rest flat on the floor or a footrest. Employers should encourage regular breaks and provide adjustable furniture to accommodate various body types. Lighting should be adjustable to minimize glare on screens. Implementing these ergonomic principles can reduce the risk of musculoskeletal disorders, eye strain, and fatigue, promoting a healthier and more comfortable computing environment for individuals in various work settings. 2) 4pts Find an image online that these each of the Optical Scanners can read.

o OCR o OMR o Bar Codes o QR Codes 3) 4pts What is RFID? Provide an example of an RFID in Use. RFID, or Radio-Frequency Identification, is a technology that uses radio waves to identify and track objects. An example is contactless payment cards, where RFID chips enable quick and secure transactions by communicating with card readers without physical contact. 4) 4pts Where Magnetic Strips are commonly found?

Magnetic strips are commonly found on credit and debit cards, identification cards, hotel key cards, and transportation cards. They store data magnetically, facilitating quick and convenient transactions or access control in various applications. 5) 4pts What is a common use for Magnetic Ink? Magnetic ink is commonly used for check printing. The ink contains magnetic particles that can be read by specialized machines during check processing, enabling automated sorting and processing in the banking industry. 6) 4pts What is a common use for a Thermal Printer? A common use for thermal printers is in receipt printing for retail and point-of- sale systems. These printers use heat-sensitive paper and are efficient for producing high-quality, fast, and cost-effective receipts in various business transactions. 7) 4pts Look online for a use for a 3D Printers? What advantages did it possess over the previous technology? 3D printers are used for rapid prototyping, custom manufacturing, and creating complex objects layer by layer from digital models. Advantages over traditional manufacturing include faster production, cost-effective small-batch production, and the ability to create intricate, customized designs with minimal waste. 8) 4pts What is the difference between Primary and Secondary Storage? Primary storage, like RAM, is volatile, fast, and temporary, holding data actively used by the CPU. Secondary storage, such as hard drives, is non-volatile, slower, and provides long-term storage for data, applications, and the operating system. 9) 4pts What are the advantages and disadvantage of using a Solid-State Drive (SSD)? Advantages of SSD: Faster data access, Durability with no moving parts, Energy-efficient, Silent operation. Disadvantages of SSD: Higher cost per gigabyte, Limited storage capacity, Limited write cycles. Data recovery challenges in case of failure. 10) 4pts Why would you defragment a HDD? Defragmenting a HDD rearranges fragmented data, consolidating scattered file parts to contiguous blocks. This improves read/write speeds, reduces access time, and enhances overall system performance by minimizing the mechanical movement of the drive's read/write heads during data retrieval. 11) 2pts When carrying your laptop around you want to avoid dropping or causing other jarring motions to avoid a Head Crash? What is a head crash?

A head crash refers to a catastrophic event in a hard disk drive (HDD) where the read/write head makes physical contact with the spinning platter. This contact can damage the magnetic coating on the platter, resulting in data loss, drive failure, and potential irreparable damage to the storage medium. To prevent head crashes, it's crucial to handle laptops with care, avoiding drops and sudden jarring motions that could lead to physical contact between the head and the platter. 12) 4pts What is a RAID? Why would you use one? RAID (Redundant Array of Independent Disks) combines multiple drives for enhanced performance, reliability, or both. It offers options like striping for speed, mirroring for redundancy, or a combination for a balance. RAID is used to optimize storage solutions in various computing environments. 13) 5pts What is a NAS? Why would you use one? A NAS (Network Attached Storage) is a dedicated file storage device connected to a network. It provides centralized data storage, access, and sharing for multiple users or devices. NAS is used for efficient data management, backups, and collaborative file sharing in home or business networks. 14) 5pts What is a SAS? Why would you use one? SAS (Serial Attached SCSI) is a high-speed data storage interface. It connects servers to storage devices, offering faster data transfer rates and improved performance compared to SATA. SAS is used in enterprise environments for high-performance and reliable data storage applications, such as servers, storage arrays, and data centers. 15) 4pts What is Geocaching? Would you be interested in doing this? Geocaching is a global outdoor treasure-hunting game using GPS coordinates. Participants hide and seek containers, or "geocaches," at specific locations marked by coordinates worldwide. It combines adventure, technology, and exploration. While I don't have personal interests, many find it a thrilling and engaging outdoor activity. 16) 4pts Which of these backup plans would be the best for a 24/7 operation? Why? Continuous Backup plan would be the most suitable. Continuous backup continuously and automatically updates changes, ensuring real- time data protection without scheduled interruptions, making it ideal for maintaining the latest information in a non-stop operational environment .  Full  Differential  Incremental  Selective  Continuous

17) 2pts Which requires the loading of the OS from nonvolatile storage (Harddrive) to volatile storage (making the OS Memory Resident)?: Options: Warm Boot or Cold Boot The process of loading the OS from nonvolatile storage (hard drive) to volatile storage (RAM) is known as a Cold Boot. A Cold Boot involves starting the system from a powered-off state, loading the operating system into memory, and initializing the system components. 18) 4pts What is Multitasking? Which processes are in the foreground? Multitasking is the simultaneous execution of multiple tasks by an operating system. Processes in the foreground are user-engaged tasks with graphical interfaces, like word processors or web browsers, actively receiving input and having a visible presence on the screen. 19) 4pts What is Virtual Memory? Virtual memory is a memory management technique where an operating system uses a combination of RAM and secondary storage to simulate a larger memory space. It enables running applications to continue functioning even when physical RAM is full. 20) 4pts What is a Virtual Machine? A virtual machine (VM) is an emulation of a computer system within a host system. It allows multiple operating systems to run on a single physical machine, enabling efficient resource utilization, isolation, and flexibility for testing or running diverse software environments. 21) 4pts Find these Specifications for the hard drive ST4000LM024? o Capacity ____4TB____ o Cache Memory ____128MB_____ o Storage Access Time ____7.5 secs_____ o Interface ____SATA III_____ o Interface Transfer Rate ___6.0 Gbps______ o Harddisk’s Rotational Speed __5400RPM____
