Components of a Computer - CORRECT ANSWER ✔✔- CPU, Memory and Storage,
Peripheral Devices
CPU - CORRECT ANSWER ✔✔- Executes programs' instructions and commands
various components in the computer. Referred to as the "chip".
Memory - CORRECT ANSWER ✔✔- Stores the programs being executed and the
data they are using.
I/O Subsystem - CORRECT ANSWER ✔✔- All peripheral devices where long term
storage devices are used.
Bus - CORRECT ANSWER ✔✔- Permits information to move between each
component; electrical channels that enable communication among the electronic
components
System Unit - CORRECT ANSWER ✔✔- Critical component of all computer based
systems; consists of most of the hardware the computer needs in order to run;
comes in a variety of shapes and sizes.

,Internal Components of the System Unit - CORRECT ANSWER ✔✔- Case, Internal
Bays, Buses, Ports, Hard Drive, Motherboard, CPU, CPU Cooler, Memory Module
(RAM), Power Supply Unit (PSU), Expansion Slots/Cards
Parts of the CPU - CORRECT ANSWER ✔✔- Control Unit (CU) - retrieves the
instructions and the raw data that is input and coordinates or controls the
sending of those instructions and data to the ALU
Arithmetic Logic Unit (ALU) - does the actual processing of the data; completing
mathematical calculations and logical operations to process the data and
converting the input of the keyboard text entry to output displayed on the screen
System Clock - CORRECT ANSWER ✔✔- Controls the speed at which instructions
are processed.
RAM - CORRECT ANSWER ✔✔- Stands for Random Access Memory.
It temporarily stores data before it is processed and sent to your screen or
printer.
It is volatile (means data or information stored disappears when the computer is
turned off or loses power).
You can choose the amount of RAM your computer has.
Types of RAM - CORRECT ANSWER ✔✔- Dynamic RAM (DRAM) - typically called
main memory

,Static RAM (SRAM) - cache memory and registers
BIOS ROM - CORRECT ANSWER ✔✔- BIOS stands for Basic Input Output System;
ROM stands for Read Only Memory.
Typically stored in ROM chip on the motherboard.
Is software not hardware, ("basic" operating system that runs when the computer
is first turned on).
Runs tests of memory and the CPU and initializes hardware components so that
the actual Operating System can be loaded from the hard disk.
Can't choose the amount or contents.
1st Generation of Computers - CORRECT ANSWER ✔✔- Vacuum tubes, relay
switches, the need to program in machine language
2nd Generation of Computers - CORRECT ANSWER ✔✔- Transistor components,
magnetic core memory, smaller size, easier to program, disk drives and drums,
called mainframe computers
3rd Generation of Computers - CORRECT ANSWER ✔✔- Silicon chips (known as ICs
- integrated circuits), reduced cost, called mini computers, networks introduced
via dumb terminals
3|Page
, 4th Generation of Computers - CORRECT ANSWER ✔✔- Single chip processor,
called microcomputer, first personal computer, rudimentary computer graphics,
home use
Moore's Law - CORRECT ANSWER ✔✔- Doubling of transistor count roughly every
18 - 24 months (exponential increase)
Evolution of Storage - CORRECT ANSWER ✔✔- Punch cards, magnetic tape, hard
disks, floppy disks, optical discs, flash memory, cloud storage
Machine/Low-level Language - CORRECT ANSWER ✔✔- Written for a specific
machine by the engineers who built and ran the computers; no need for OS since
only one program could run at a time
Assembly Language - CORRECT ANSWER ✔✔- Easier than machine but still
required detailed, precise low level instructions
Language Translator Programs - CORRECT ANSWER ✔✔- Function is to translate
one program language into another; take source code and convert it to another
form; source code by itself cannot be read by a computer
Compiler - CORRECT ANSWER ✔✔- Improve language translator; requires that the
components of the software all be defined before compilation can begin; code is
more effcient
