System Software and Operating Systems Quiz

Evaluating Computer Components

• Various types of computers to choose from including tablets, ultrabooks, netbooks, tablet PCs, laptops, and desktops
• The CPU is located on the motherboard, processes instructions, performs calculations, and manages flow of information
• The CPU consists of a control unit and an Arithmetic Logic Unit (ALU) and goes through a machine cycle of fetch, decode, execute, and store
• CPU processing power is determined by clock speed, overclocking, number of cores, and cache memory
• RAM is short-term, volatile memory, while ROM stores start-up instructions and is permanent nonvolatile storage
• Types of RAM include DDR3 and DDR5, found in different devices and video graphic cards
• Mechanical hard drives consist of coated platters stacked on a spindle, while solid-state drives have no mechanical parts and are faster and quieter
• Optical drives include Blu-ray, which delivers high definition quality and is used by large displays and monitors
• RAID technology, such as RAID 0 for speed and RAID 1 for security, can be used in hard drives
• Video display quality depends on the video card, monitor, ports, video memory, and GPU
• Audio quality is affected by speakers, sound card, 3-D sound technology, surround sound, and Dolby Digital 7.1
• Proper upkeep and maintenance can improve system reliability and performance, and disposing of old computers should be done responsibly to minimize environmental impact

Network Components and Home Networking

• The network components include transmission media such as wireless and wired networks, with examples of UTP cable types and hardware like network adapters, modems, routers, and switches.
• Network software can be operating software for P2P networking or client/server network, communicating through a centralized server with specialized network operating system (NOS) software.
• Connecting to the internet involves sharing an internet connection through specialized providers or companies and using broadband technologies like satellite, cable, DSL, and fiber optic services.
• Wireless internet access options include WiFi hotspots, wireless in-flight internet, and mobile broadband technologies like 3G and 4G LTE.
• Home network installation and configuration involve securing wireless networks, identifying devices, connecting various devices like smartphones, gaming consoles, tablets, and printers, and using routers for Windows or Apple computers.
• Specialized home networking devices include NAS devices, AirPort Time Capsule, digital picture frames with built-in wireless access, and wireless monitoring cameras for security.
• Troubleshooting wireless network problems may involve using dual-band N routers or wireless range extenders for added performance options.
• Securing wireless networks is crucial due to the added vulnerabilities of wireless networks, such as signal range extending to neighbors, and the need for extra precautions to secure wireless connections.
• Check Your Understanding questions cover various topics, including network advantages and disadvantages, types of networks, home network components, connecting to the internet, and securing wireless networks.
