BTE 210 Exam 1 Questions and Answers 100% Correct Graded A+ 2026/27
Computer's Hardware - The physical equipment used for the input, processing, output,
and storage activities of a computer system
Central Processing Unit (CPU) - manipulates the data and controls the tasks performed by
the other components
Primary Storage - temporarily stores data and program instructions during processing
Secondary Storage - stores data and programs for future use
Input Technologies - Accept data and instructions and convert them to a form that the
computer can understand
Output technologies - present data and information in a form people can understand
Communication technologies - provide the flow of data from external computer networks
(Internet) to the CPU, and from the CPU to computer networks
Types of Servers - Supercomputers, mainframe computers
Supercomputers - the fastest computers available at any time.
,Who uses supercomputers? - Due to the high cost they are generally used by large
organizations (military, scientific research) to execute computationally demanding tasks
involving large data
Mainframe Computers - computers at the high end of the performance and reliability
scales and can handle millions of transactions per day
Types of Clients - microcomputers (desktop PCs), laptops, tablets, wearable clients
Microcomputers - the smallest and least expensive category of general-purpose computers
Laptops - small, easily transportable, lightweight microcomputers
Tablets - a complete computer contained entirely in a flat touchscreen
Wearable clients - apple watch
Types of Primary Memory (main memory) - register memory, cache memory, random
access memory (RAM), read only memory (ROM)
Cache Memory - Primary memory- High speed memory that enables the computer to
temporarily store blocks of data that are used more frequently
, Register Memory - Primary Memory- part of the CPU. Has the least capacity and stores
data only immediately before and after processing. located closer to CPU than the RAM
Random Access Memory (RAM) - Primary memory- holds a software program and small
amounts of data for processing
Read only Memory (ROM) - Primary Memory- type of chip where certain critical
instructions are held and retains these instructions even when the computer is off
Types of Secondary Storage - Magnetic tape, magnetic discs, solid state drives (SSD),
Optical storage devices, Flash memory (memory cards)
Magnetic tape - secondary storage- on a large open reel or in a smaller cartridge or
cassette
Magnetic Discs - secondary storage- most widely used
Solid state drives (SSD) - secondary storage- serve the same purpose as a hard drive and
store data in memory chips, but do not have moving parts
Optical storage devices - secondary storage- laser reads the surface of a reflective plastic
platter
