What are these examples of?
-Printer
-Mouse
-Moniter
-Keyboard
-Scanner
Explanation
The given examples are all physical devices that are used in conjunction with a computer system. They are all types of hardware components that serve specific functions in order to input, output, or process data. The variations in capitalization ("Hardware, hard ware, Hard ware") may indicate different levels of specificity or categorization within the broader concept of computer hardware.
2.
1,000 characters are equal to what?
Correct Answer(s)
A. 1,000 bytes
B. 1 kilobyte
Explanation
1,000 characters are equal to 1 kilobyte. In computer science, a kilobyte is a unit of digital information that is equal to 1,000 bytes. Therefore, 1,000 characters can be represented by 1 kilobyte of data.
3.
What memory is Non-Volatile
Correct Answer(s)
ROM, Read only Memory, Read Only Memory, read only memory
Explanation
ROM (Read Only Memory) is a type of memory that retains its data even when the power is turned off. It is non-volatile, meaning that the data stored in ROM remains intact even when there is no power supply. ROM is typically used to store permanent instructions or data that should not be modified, such as firmware or software instructions. Unlike volatile memory, such as RAM, ROM does not require constant power to retain its data, making it a reliable storage option for essential system instructions.
4.
What is used for encoding the alphabet?
Correct Answer
C. Bytes
Explanation
Bytes are used for encoding the alphabet. In computer systems, characters are represented using a set of binary digits called bits. A byte is a unit of digital information that consists of 8 bits. Each character in the alphabet is assigned a unique binary code, which is then stored and transmitted using bytes. This allows computers to process and display text by converting the encoded bytes back into readable characters.
5.
What type is this included in?
-Wordprocessing
-Spreadsheets
-Games
-DPT
Correct Answer
B. Software
Explanation
This question is asking about the type of category that the given item is included in. The options provided are "Wordprocessing," "Spreadsheets," "Games," and "DPT." The correct answer is "Software" because all of the options provided are types of software, and the question is asking about the category that the item belongs to.
6.
1,000 megabytes =
Correct Answer
D. 1 gigabyte
Explanation
The correct answer is 1 gigabyte because 1,000 megabytes is equal to 1 gigabyte.
7.
1,000 kilobytes =
Correct Answer
C. 1 megabytes
Explanation
The correct answer is 1 megabyte because 1,000 kilobytes is equal to 1 megabyte. In the metric system, kilo represents a factor of 1,000, so when you have 1,000 kilobytes, it is equivalent to 1 megabyte.
8.
What does RAM stand for?
Correct Answer
Random Access Memory, random access memory
Explanation
RAM stands for Random Access Memory. It is a type of computer memory that allows data to be stored and retrieved quickly by the computer's processor. Unlike other types of memory, such as hard disk storage, RAM is volatile, meaning that its contents are lost when the computer is powered off. Random access refers to the ability to access any memory location directly, rather than sequentially. This allows for fast and efficient data retrieval, making RAM an essential component in modern computers.
9.
How many bits to make a byte?
Correct Answer
A. 8 bits
Explanation
A byte is a unit of digital information that can store 8 bits. Therefore, to make a byte, you need 8 bits.
10.
Give me a characteristic of Hardware.
Correct Answer
Something you can touch and see., Something you can touch., Something you can see.
Explanation
Hardware refers to the physical components of a computer or electronic device. It includes tangible objects that can be physically touched and seen, such as the computer itself, its keyboard, monitor, mouse, and other peripherals. These physical components are essential for the functioning of the device and enable users to interact with it.
11.
What is the Binary Code?
Correct Answer
E. 0 and 1
Explanation
The binary code is a system of representing information using only two digits, 0 and 1. In this system, each digit is called a bit, and a combination of bits represents different characters, numbers, or instructions. It is the fundamental language of computers and digital systems.
12.
The CPU is also known as the what of the computer?
Correct Answer
Brain, brain
Explanation
The CPU is often referred to as the "brain" of the computer because it is responsible for executing instructions and performing calculations. It controls and coordinates all the activities of the computer, just like the brain controls and coordinates all the functions of the human body. The CPU processes data, performs calculations, and manages the flow of information between different components of the computer system. It is the most important component of a computer, just like the brain is the most vital organ in the human body.
13.
What is the speed of the CPU?
Correct Answer
B. Megahertz
Explanation
The speed of the CPU is measured in hertz, which represents the number of cycles per second. Megahertz (MHz) is a unit of measurement equal to one million hertz, and it is commonly used to describe the speed of CPUs. Therefore, the correct answer is Megahertz.
