WGU C182- INTRODUCTION TO IT
True or False - Software uses program languages to guide the specific actions of a computer. -
(answer)True
True or False - Computer memory is not considered hardware. - (answer)False
Memory is part of a computer's hardware.
True or False - Database management software is an example of system software. - (answer)False
Database management software is an example of application software; it is not an operating system.
Yes or No - Software programming language instructions can be general and fairly broad. - (answer)No
Software programming language instructions are descriptive and break tasks down into definable steps.
Yes or No - Software is tangible, like computer hardware. - (answer)No
Software is intangible; it is a set of instructions written in a programming language.
Yes or No - Software tells the computer how to execute commands whereas hardware is the physical
devices that make up a computer system. - (answer)Yes
True or False - GUI (Graphical User Interface) operating systems improved the ease of using a computer
making computers more accessible to individuals without special training. - (answer)True
True or False - In the 1940s-1970s, most computer processing did not require user interaction. -
(answer)True
The user would specify a program, send it off to the computer to run, and return later for the output.
What is TCP/IP - (answer)Network protocol stack
TCP/IP is made up of a collection of protocols referred to as a protocol stack.
,What are the 4 operations a computer performs? - (answer)Input, Processing, Output, Storage
Referred to as IPOS
What is the definition of a computer system? - (answer)A collection of computer hardware, software,
users and networks
What are the 2 categories of software? - (answer)1. Systems software, includes the OS and all the
utilities that enable the computer to function
2. Applications software, includes programs that do real work for users. example word processors,
spreadsheets, db management
True or False - Database management software is an example of system software. - (answer)False - DB
management software is an example of application software; it is not an operating system
True or False - In the 1940s-1970s, most computer processing did not require user interaction. -
(answer)True - the user would specify a program, send it off to the computer to run, and return later for
the output
What are the four components of computer systems? - (answer)1. CPU - ALU, control Unit, Registers
2. Memory - SCRAM, DRAM, ROM
3. Input/Output (I/O) subsystem
4. The bus
Executes instructions and commands computer components - (answer)CPU
Contains peripheral devices used for input, output, and long-term storage - (answer)I/O subsystem
Stores programs being executed and data that the programs use - (answer)Memory
A collection of wires, cables, optical fiber, or printed circuits that allow multiple hardware components
to communicate with each other. - (answer)Bus
What does the ALU do? - (answer)It does the actual processing of the data
What does the CU do? - (answer)It retrieves the instructions and raw input data and sends that data for
processing
What is the measurement unit used to identify "Clock Speed" on today's computers? - (answer)GHz
What is ROM - (answer)Read only memory - it holds the instructions the computer needs to boot
, What is RAM - (answer)Random access memory - short term storage made up of DRAM - dynamic RAM
called the main memory and SRAM static RAM the cache memory and registers.
RAM temporarily stores data before it is processed and sent to your screen or printer. RAM storage is in
the 1-8 GB range.
What are peripheral devices? - (answer)Components that are located outside the system unit, yet are
connected physically or wirelessly to it. Examples, keyboard, mouse, speakers, monitor
What are the external components that allow peripherals to be connected to the system unit? -
(answer)Bays (CDs, DVDs), slots (wireless-access cards, camera cards), ports (input, output, storage,
communication devices)
Difference between a desktop PC system and a notebook/laptop computer? - (answer)The peripherals
and system unit of a notebook/laptop are sold as a single unit.
Which input peripherals are now integrated in the laptop? - (answer)Mouse, keyboard, and webcam
What sped the need to build better faster computers? - (answer)Needed to assist in computing rocket
trajectories after World War II
What was the first digital, general-purpose, programmable computer? - (answer)ENIAC (Electronic
Numerical Integrator and Computer) first known to the public in February of 1946
- data input was performed by punch cards
- output was produced using an offline accounting machine
- performed decimal computations
- vacuum tubes for storage
- transistors and other electronics for computation
- programming was in machine language
This ended all interest in analog computers
General-purpose computer - (answer)can conceivably execute any program that can be written for that
computer
Transistor components - (answer)- favored over vacuum tubes
