Introduction to Computer Basics: Input deivices and Binary Code.

• 1.

The four main processes of the computer are:

• A.

Input, processing, storage, output

• B.

Input, CPU, storage, output

• C.

Computer, processing, storage, output

• D.

Input, processing, view, print

A. Input, processing, storage, output
Explanation
The correct answer is "Input, processing, storage, output". This is because these four processes are the fundamental steps in the functioning of a computer system. Input refers to the data or instructions that are entered into the computer, processing involves the manipulation and transformation of the input data by the central processing unit (CPU), storage involves the retention of data and instructions for later use, and output refers to the presentation or display of the processed data or results.

Rate this question:

• 2.

Which of the following is/are the main operations of the computer? Select all that apply...

• A.

Arithmetic Operations

• B.

Logical Comparison Values

• C.

Storage and Retrieval Options

A. Arithmetic Operations
B. Logical Comparison Values
C. Storage and Retrieval Options
Explanation
The main operations of a computer include arithmetic operations, logical comparison values, and storage and retrieval options. Arithmetic operations involve performing mathematical calculations such as addition, subtraction, multiplication, and division. Logical comparison values involve comparing values to determine if they are equal, greater than, or less than each other. Storage and retrieval options refer to the ability of a computer to store and retrieve data from various storage devices such as hard drives, solid-state drives, and memory cards. These operations are essential for the functioning of a computer system.

• B.

False

A. True
Explanation
The given statement is true. The order of computers from largest/fastest/most expensive to smallest/slowest/least expensive is as follows: Supercomputer, Mainframe computer, Mini computer, and microcomputer. Supercomputers are the largest, fastest, and most expensive computers, followed by mainframe computers, mini computers, and microcomputers, which are the smallest, slowest, and least expensive.

Rate this question:

• 4.

Which of the following are the MAIN parts of the computer. Select ALL that apply...

• A.

Input Devices

• B.

Output Devices

• C.

Central Processing Unit

• D.

Memory

• E.

Storage Devices

A. Input Devices
B. Output Devices
C. Central Processing Unit
D. Memory
E. Storage Devices
Explanation
The main parts of a computer include input devices, output devices, the central processing unit (CPU), memory, and storage devices. Input devices allow users to input data into the computer, such as keyboards or mice. Output devices display or present the processed information, like monitors or printers. The CPU is the brain of the computer, responsible for executing instructions and performing calculations. Memory refers to the temporary storage space used by the computer to hold data and instructions while they are being processed. Storage devices are used for long-term data storage, such as hard drives or solid-state drives.

Explanation
The touchpad is a device that allows users to input commands or interact with a computer or electronic device by touching the surface of the pad. It is primarily used as an input device, allowing users to move the cursor, click, scroll, and perform other actions on the screen. Therefore, "Input" is the correct answer as it accurately describes the function of a touchpad.

B. Output
• 11.

Keyboard (Select all that apply)

• A.

Input

• B.

Output

A. Input
Explanation
The correct answer is "Input" because a keyboard is primarily used to input data or commands into a computer or other electronic device. It allows the user to type letters, numbers, and symbols, as well as perform various other functions such as controlling volume, navigating through menus, and executing shortcuts.

• C.

Storage

A. Input
B. Output
C. Storage
Explanation
The correct answer is Input, Output, Storage because a flash drive can be used for multiple purposes. It can be used to input data from a computer or other devices, such as transferring files or saving documents. It can also be used for output, such as playing media files or displaying documents on a compatible device. Additionally, a flash drive is primarily used for storage, allowing users to save and carry data with them conveniently.

Digitizing is the process of taking a visual image, or audio recording and converting it to a binary form for the computer.

• A.

True

• B.

False

A. True
Explanation
Digitizing refers to the process of converting visual images or audio recordings into a binary format, which can be understood and processed by a computer. This involves capturing the analog information and encoding it into a digital representation using binary code, consisting of 0s and 1s. Therefore, the statement "Digitizing is the process of taking a visual image or audio recording and converting it to a binary form for the computer" is true.

Rate this question:

• 15.

There are two types of input devices; those that deal with original data and those that deal with new data.

• A.

True

• B.

False

B. False
Explanation
There are two types of input devices; those that deal with original data and those that deal with previously store data.

Rate this question:

• 16.

Original data is the data that the computer had originally when you bought it.

• A.

True

• B.

False

B. False
Explanation
Original data is NEW data - something that YOU entered into the computer.

Rate this question:

• 17.

A bit is the fundamental unit of information. Multiple bits make up a byte and multiple bytes make up a word. How many bits are in a byte? How many bits are typically in a word (according to most IBM computers)?

• A.

4; 16

• B.

6; 24

• C.

8; 32

• D.

10; 40

C. 8; 32
Explanation
A byte is made up of 8 bits, which is the standard unit of information in most computer systems. On the other hand, a word in most IBM computers typically consists of 32 bits.

Rate this question:

• 18.

How many bytes make up a word (on most IBM computers)?

• A.

16

• B.

32

• C.

8

• D.

4

D. 4
Explanation
On most IBM computers, a word is typically made up of 4 bytes. This means that a word is represented by 32 bits of data. Each byte consists of 8 bits, so when 4 bytes are combined, it results in a word. This is a common configuration in IBM computers, although it is important to note that different computer systems may have different word sizes.

Based on the activities, what is the smallest number that we can represent in binary code?

• A.

0

• B.

1

• C.

-1

• D.

-2

A. 0
Explanation
The smallest number that can be represented in binary code is 0. In binary code, the digit 0 represents zero, while the digit 1 represents one. Therefore, 0 is the smallest number that can be represented in binary code.

A transistor is what determines whether or not a 1 or a 0 is present by either being "on" or "off".

• A.

True

• B.

False

A. True
Explanation
A transistor is a semiconductor device that can amplify or switch electronic signals and electrical power. In digital systems, transistors are used to represent binary states, with "on" representing 1 and "off" representing 0. Therefore, it is true that a transistor determines whether a 1 or a 0 is present by being "on" or "off".
