Study Notes
Evaluating Computer Subsystems and Making Decisions
- Different types of computers include tablets, ultrabooks, netbooks, tablet PCs, laptops, and desktops, each with varying mobility and processing power.
- The CPU, located on the motherboard, processes instructions, performs calculations, and manages information flow, with notable Intel i5 and i7 processors.
- The CPU is composed of a control unit and an Arithmetic Logic Unit (ALU), with a machine cycle including fetch, decode, execute, and store steps.
- Factors affecting CPU processing power include clock speed, overclocking, cores, cache memory, and hyperthreading.
- Random access memory (RAM) serves as short-term volatile storage, while read-only memory (ROM) stores start-up instructions and provides permanent nonvolatile storage.
- Different types of RAM include DDR3 and DDR5, with memory modules such as dual inline memory modules (DIMMs) determining the required RAM.
- Storage subsystem options include mechanical hard drives, solid-state drives (SSDs), and optical drives, each with unique characteristics and capacities.
- RAID technology, such as RAID 0 for speed and RAID 1 for security, presents considerations for storage needs and capacity.
- Video and audio subsystems impact the quality of video and sound on a computer, influenced by components like video cards, monitors, and sound cards.
- Evaluating system reliability involves considering performance problems, proper upkeep, and maintenance for making a final decision on computer subsystems.
- Environmental impact and data security are important considerations when disposing of old computers, with options to donate and remove data before doing so.
- A comprehensive understanding of the CPU, memory, storage, video, and audio subsystems is essential for evaluating and making decisions about computer hardware.
Home Network Setup and Security
- Network components include transmission media, such as wireless and wired networks, with UTP cable types like Cat 5E, Cat 6, and Cat 6a.
- Basic network hardware includes network adapters, NICs, broadband modems, packets, routers, and switches.
- Network software includes operating software for P2P and client/server networks, which communicate through centralized servers or specialized NOS software.
- Connecting to the internet involves home networks sharing internet connections and purchasing internet access from ISPs.
- Broadband internet connections can be established through standard broadband technologies, satellite broadband, and mobile broadband.
- Wired broadband internet connections include cable internet, DSL, and fiber optic service.
- Wireless internet access can be achieved through WiFi hotspots, wireless in-flight internet, and mobile broadband like 3G and 4G LTE.
- Installing and configuring home networks involves securing wireless networks and connecting devices such as smartphones, gaming consoles, tablets, smart TVs, computers, and printers.
- Devices like routers for Windows and Apple computers, NAS devices, and specialized home-networking devices like digital picture frames and wireless monitoring cameras are used in home networks.
- Troubleshooting wireless network problems may involve using dual-band N routers or wireless range extenders for performance options.
- Wireless networks are more vulnerable to security risks than wired networks and require special precautions to ensure security, such as using firewalls and securing internet connections.
- Understanding home networks involves knowing the advantages and disadvantages of networks, classifying networks, identifying network components, connecting to the internet, and configuring home networks and devices.
