Correct Answers.
Computer's Hardware - Answer- The physical equipment used for the input, processing,
output, and storage activities of a computer system
Central Processing Unit (CPU) - Answer- manipulates the data and controls the tasks
performed by the other components
Primary Storage - Answer- temporarily stores data and program instructions during
processing
Secondary Storage - Answer- stores data and programs for future use
Input Technologies - Answer- Accept data and instructions and convert them to a form
that the computer can understand
Output technologies - Answer- present data and information in a form people can
understand
Communication technologies - Answer- provide the flow of data from external computer
networks (Internet) to the CPU, and from the CPU to computer networks
Types of Servers - Answer- Supercomputers, mainframe computers
Supercomputers - Answer- the fastest computers available at any time.
Who uses supercomputers? - Answer- 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 - Answer- computers at the high end of the performance and
reliability scales and can handle millions of transactions per day
Types of Clients - Answer- microcomputers (desktop PCs), laptops, tablets, wearable
clients
Microcomputers - Answer- the smallest and least expensive category of general-
purpose computers
Laptops - Answer- small, easily transportable, lightweight microcomputers
, Tablets - Answer- a complete computer contained entirely in a flat touchscreen

Types of Primary Memory (main memory) - Answer- register memory, cache memory,
random access memory (RAM), read only memory (ROM)
Cache Memory - Answer- Primary memory- High speed memory that enables the
computer to temporarily store blocks of data that are used more frequently
Register Memory - Answer- 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) - Answer- Primary memory- holds a software program
and small amounts of data for processing
Read only Memory (ROM) - Answer- 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 - Answer- Magnetic tape, magnetic discs, solid state drives
(SSD), Optical storage devices, Flash memory (memory cards)
Magnetic tape - Answer- secondary storage- on a large open reel or in a smaller
cartridge or cassette
Magnetic Discs - Answer- secondary storage- most widely used
Solid state drives (SSD) - Answer- 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 - Answer- secondary storage- laser reads the surface of a
reflective plastic platter
Flash Memory (memory cards) - Answer- nonvolatile electronic storage devices with no
moving parts and use 30x less battery power than hard drives
Advantages of flash memory - Answer- smaller and more durable than hard drives
Types of computer memory - Answer- primary memory (main memory), secondary
memory
Role of software - Answer- users communicate with application softwares, which
communicate with systems software, which communicate with hardware
