Juana Ortiz-V.Chapter 5 PowerPoint SolutionsDescribe the four most common types of personal computers. Desktop: system units located in separate case, all in one computer combines system unit and monitor.Laptop: system units contain secondary storage devices and input devices.Tablet: system units are located behind the monitor. They are smaller, lighter, and generally less powerful than laptops and use a virtual keyboard.Mobile Devices: handheld computers that fit comfortably in one hand. Most popular.Describe system boards including sockets, chips, chip carriers, slots, and bus lines.System boards is the mainboard/motherboard, controls all communication for the computer system and all external and internal devices and components are connected to it.-Sockets: provide connection points for chips.-Chips: are mounted on chip carriers.-Slots: provide connection points for specialized cards or circuit boards.-Bus lines: provide pathways to support communication.Discuss microprocessor components, chips, and specialty processors.Microprocessor is contained on a single chip, it has two basic components; control unit and ALU.-Microprocessor Chips: a word the number of bits that can be accessed by the microprocessor at one time. Clock speed represents the number of times the CPU can fetch and process data or instructions in a second.-Specialty Processors: include graphics coprocessors (GPU/Graphics Processing Unit), and processors in automobiles.Define computer memory including RAM, ROM, and flash puter memory holds data, instructions, and information.-RAM (Random-Access Memory): chips are called temporary or volatile storage because their contents are lost if power is disrupted. (Cache Memory, DIMM, Virtual Memory)-ROM (Read Only Memory): chips are nonvolatile storage and control essential system operations.-Flash Memory: do not lose its contents when power is removed.Define expansion slots, cards, Plug and Play, PC cards, PCMCIA slots, and Express-Card puters that allow users to expand their systems by providing expansion slots on their system boards to accept expansion cards. Plug and Play is the ability for a computer to recognize and configure a device without human interaction. PC cards plug into PCMCIA slots and Express Card slots to accept credit card sized expansion cards.Describe bus lines including bus width, system bus, and expansion bus.Bus lines provide data pathways that connect various system components. Bus width is the number of bits that can travel simultaneously. System busses connect CPU and memory. Expansion buses connect CPU and slots. Define ports including standard and specialized ports. Give examples of each.Ports are connecting sockets on the outside of the system unit. There are only four types of standard ports:-VGA and DVI; the provide connections to monitors.-USB; are widely used to connect keyboards, mice, printers, and storage devices.-FireWire; provides high speed connections to FireWire devices such as camcorders and storage devices.-Ethernet; high speed networking port that has become a standard for many of today’s computers.Specialized Ports only have five types:-eSTATA; for high speed connections to large secondary storage devices.-HDMI: for high definition digital audio and video.-MIDI: for digital music.-MiniDP, mDP: for large monitors.-Thunderbolt: for high speed connections up to seven separate devices connected one to another.Describe power supply including power supply units and AC adapters.Power supply units convert AC to DC and power desktops. AC adapters power laptops and tablets and recharge batteries.Discuss electronic data and puters only recognize digital electronic signals before any processing can occur within the system unit a conversation must occur in order for the system to understand and electronically process. ................
