Exam 3 Flashcards
a programmable electronic device that can store, retrieve, and process data
definition of a computer
5 fundamental operations of a computer
input, processing, storage, output, communication
largest circuit boards, all the important small components are connected to it
motherboard
small chip located on the mother board, brains of computer
central processing unit (CPU)
contains instructions which help boot up the computer
files
real time clock that has configuration information about the computer
CMOS (complimentary metal oxide system)
working memory, allows you to run multiple programs on the computer
random access memory (RAM)
different connectors that stick out of the PC that link to adapter cards, printers scanners, keyboards, mouse
ports
series of connections or controllers and chips on the PC that creates the information highway on the computers
bus
what can help the PC or computer to connect to the internet
network card
the thing that delivers all the electricity to the PC and keep the computer cool
power supply
to produce sound or listen to something you need a _________ it’s part of the computer and attaches to the motherboard
sound card
where all your documents and your programs are stores where the repository for that is going to be on
hard drive
inputs for computer
mouse, joystick, game controller, microphone, video camera
what are some of the different monitors?
LED
LCD
cathode ray tube (CRT): uses a cathode and anode, pushes electrons across to hit a phosphor, we don’t use CRT much anymore
software that controls the computer, the hardware acts as a bridge between the applications and the hardware
operating system
language used by computer (0s and 1s), combination of these gives meaning to computer
binary code
a larger network (distance) that covers a larger area (cities, states, countries) the internet is and example of this
WAN (wide area network)
a smaller network (distance) that is usually confined to a building. it is like a little internet or intranet
LAN (local area network)
a communication platform that connects 2 or more computing objects together to share information and resources
network
different network classifications
peer to peer, server based, client based
peer to peer =
computer to computer
centralized computer that controls the operation files, sometimes the program of the computer are attached to it
server based
a centralized computer that controls the operations of the networks. rather than sending entire original resource to the client for processing, the server processes the resource as requested by the client and returns it only to that specific client. more specific than server based
client based
robust computer that manages resources for other computer network devices
server
where the software is all on the server and that server is attached to different physician offices
thin client
standalone, independent, everything that’s needed is on that computer and not on a server
thick client
it sends data only to those devices to which the data are directed. It is more specific in how it sends data to the target/destination, this reducing network traffic. It is not used in small business or at home networks because there is not enough traffic.
network switch
created so that larger networks can be segmented or broken up into smaller networks to reduce traffic within the network. These segments are then connected this
network bridge
a networking device that forwards data packets between computer networks
router
a network structure where all devices are connected to a single cable, that functions as a shared communication medium
network topology: bus
a network design where devices are connected in a circle, forming a closed loop that allows data to travel in one direction
network topology: ring
a network structure where all devices are connected to a central hub
network topology: star
a hierarchical structure that resembles a tree, with a central node (root) and multiple levels of child nodes
network topology: tree
a network that has multiple pathways interconnecting devices and networks
network topology
