BTE 210 Exam 1 Review Exam Questions And Correct Answers
Supercomputers
Fastest computers used by large organizations
Expensive
Can perform complex calculations and process large amounts of data at high speeds
Mainframe Computers
Reliable high-end performance computer that handles millions of
transactions/computing tasks per day for businesses
Midrange Computers (aka minicomputers)
Relatively small, cheap, perform like mainframes to a limited extend (more powerful than
a PC but still less powerful than a mainframe)
Microcomputers (aka Personal computers, PCs)
Smallest, least expensive general-purpose computers
Information System
Input(devices)→ Process(or) → Output (devices)
Primary storage device
A device used to temporarily store data that is actively being processed or used by the
CPU
,Aka internal memory
Examples of primary storage devices: RAM, Cache memory, Read-only memory (ROM)
Central Processing Unit (CPU)
Computer's brain, works with primary and secondary storage devices
Bit
Smallest unit of data, represented by 0 's(off) or 1's(on)
Byte
Smallest addressable(we can control it) unit of data
8 bits = 1 byte
American Standard Code for Information Interchange (ASCII)
Computer language for information interchange
Input Devices
Accept data and instructions and convert them to a form that a computer can
understand
Output Devices
Convert data for human understanding
Hard Drive
, Stores data permanently, impacts computer performance;
Ex. When you're playing a game, it has to load because the data that stored on the hard
drive is being moved to the RAM
Random Access Memory (RAM)
Temporary data storage for running apps
More RAM = More speed
More RAM = Smoother multi-tasking and better performance when running
resource-intense applications
Graphics Card
Controls display pixels for screen quality; it knows which pixels to light up and when to
light them up
This is the most difficult part of sending data through for your computer
Motherboard
Circuit board that connects all other components and allows them to talk to each other
Read Only Memory ROM
Loads basic startup info when computer is powered on
Input/output devices
Enable interaction with the computer.
