INTRODUCTION TO IT VERSION A
What 4 processes does a computer perform? - ANSWER - (I)nput, (P)rocessing, (O)utput, (S)torage - IPOS
In the IPOS process, what performs the Input of data (data, numbers, images and sounds)? - ANSWER - The user
In the IPOS process, what performs the Processing of the data into Information? - ANSWER - The computer
In the IPOS process, how is the information Output? - ANSWER - Depending on what is needed by the user, the computer may output the information for the user by displaying words on the monitor, printing on paper or transmitting audio over speakers
What is hardware? - ANSWER - The physical components of the computer. This includes all of the internal and external parts of a computer.

pg. 2 What is software? - ANSWER - The programs and other operating information used by the computer. Software can be shared between computers when part of a network.
What is a network? - ANSWER - A collection of computers and resources connected by various media so they can communicate with each other
What are users? - ANSWER - The people who use the computer system
What is system software? - ANSWER - Includes the operating system and all the utilities that enable the computer to function
What is application software? - ANSWER - Includes programs that do real work for users (Word, Excel, etc)
Who were the earliest computer users? - ANSWER - The engineers who built and programmed them
What has allowed computers to become easier to use for most users? - ANSWER - GUI interfaces
What advantages do Networks provide? - ANSWER - The ability to share information, share hardware such as a printer, and even share software. Cost savings can also be had due to resource sharing.

pg. 3 What is the most commonly used network protocol? - ANSWER - TCP/IP, also referred to as a protocol stack
What is a network protocol? - ANSWER - Provides the rules by which networks communicate with each other
What are the 4 major components of a computer? - ANSWER - CPU, memory, I/O subsystem and bus
What does the CPU do? - ANSWER - The device that not only executes your programs' instructions, but also commands the various components in the computer.
What does memory do? - ANSWER - Stores the program(s) being executed and the data that each program is using
What does the I/O subsystem do? - ANSWER - Includes all peripheral devices (input, output, storage, network) where storage consists of the long-term storage devices (disk drives, tape)
What does the bus do? - ANSWER - The device that permits information to move between each component. The bus transfers data between computer components using hardware such as wires, optical fiber, or printed circuit boards with traces that electrically connect various components. The size, or width, of a bus indicates how much data, or bits, can be transmitted at one time.

pg. 4 What was the first digital, general-purpose, programmable computer? - ANSWER - ENIAC (Electronic Numerical Integrator and Computer)
What characteristics did first generation computers share? - ANSWER - Reliance on vacuum tubes, relay switches, and the need to program in machine language
What characteristics did second generation computers share? - ANSWER - They used transistor components rather than vacuum tubes, which could be mass produced and last for up to 50 years. They also used magnetic core memory., which increased the memory capacity.
When were mainframes introduced and computer no longer restricted to government labs or universities? - ANSWER - The second generation.
What characteristics did third generation computers share? - ANSWER - Silicon chips (AKA IC)
When were minicomputers, dumb terminals and families of computers introduced? Small businesses were also able to begin using computers. - ANSWER - The third generation
When was the software development field introduced? - ANSWER - The third generation
When was the single-chip processor introduced? - ANSWER - The fourth generation
