Which cable is used to connect a hard drive to a motherboard?
Correct Answer
A. A SATA Cable
Explanation
A SATA cable is used to connect a hard drive to a motherboard. SATA (Serial Advanced Technology Attachment) is a type of data transfer interface that is commonly used for connecting storage devices like hard drives and solid-state drives to a computer's motherboard. It provides a fast and reliable connection, allowing for high-speed data transfer between the hard drive and the motherboard. SATA cables have replaced the older IDE (Integrated Drive Electronics) cables, which were used for a similar purpose but had slower data transfer speeds. USB and PS2 cables are not typically used for connecting hard drives to motherboards.
2.
A keyboard is a/an ______ device.
Correct Answer
A. Input
Explanation
A keyboard is an input device because it allows the user to input data and commands into a computer or other electronic device. The user can type letters, numbers, and symbols on the keyboard, which are then recognized and processed by the computer. Therefore, a keyboard serves the purpose of inputting information into a device.
3.
What is a URL?
Correct Answer
B. Uniform Resource Locator
Explanation
A URL stands for Uniform Resource Locator. It is a string of characters that is used to address and locate resources on the internet.

Which of these is a free operating system?
Correct Answer
A. Ubuntu
Explanation
Ubuntu is a free operating system because it is an open source software, meaning that its source code is freely available for anyone to view, modify, and distribute. This allows users to use Ubuntu without any cost and also gives them the freedom to customize and adapt the operating system to their needs. Unlike Windows 7, Windows XP, and Mac OSX, which are proprietary operating systems, Ubuntu is free to use and promotes the principles of open-source software.
5.
What is RAM/DRAM?
Correct Answer
A. Random Access Memory
Explanation
RAM, also known as Random Access Memory, is a type of computer memory that allows data to be read from and written to in any order, regardless of the physical location of the data. It is a volatile memory, meaning that its contents are lost when the power is turned off. RAM is an essential component of a computer system as it provides temporary storage for data and instructions that are actively being used by the CPU. It allows for fast access to data, enabling efficient multitasking and overall system performance.
6.
Which of these is a type of RAM/DRAM?
Correct Answer
A. DDR3
Explanation
DDR3 (Double Data Rate 3) is a type of RAM (Random Access Memory) or DRAM (Dynamic Random Access Memory). It is a common type of memory used in computers and other electronic devices. The other options, "DDR79-9-8" and "DRR3-PC2700," do not represent valid types of RAM.
7.
What is a Universal Serial Bus?
Correct Answer
A. USB Port
Explanation
A Universal Serial Bus (USB) is a standard connection that allows devices to be connected to a computer or other electronic device. It is a widely used interface for connecting peripherals such as keyboards, mice, printers, and external storage devices to a computer. USB ports are found on most computers and are used to transfer data and provide power to connected devices. SATA and HDMI ports, on the other hand, are different types of connections used for specific purposes such as connecting storage devices or audio/video devices respectively. Therefore, the correct answer is USB Port as it encompasses all the mentioned options.
8.
What would you use this cable for?
Correct Answer
A. Connecting a computer to a monitor.
Explanation
This cable would be used for connecting a computer to a monitor. It is not used for connecting to the internet or connecting a USB flash drive to a computer. Therefore, the correct answer is connecting a computer to a monitor.
9.
Examples of peripheral devices are
Correct Answer
D. All of the above
Explanation
The correct answer is "All of the above" because all the mentioned options, including the monitor, keyboard, and mouse, are examples of peripheral devices. Peripheral devices are external hardware components that connect to a computer and provide input/output capabilities, enhancing the functionality of the computer system. These devices are not essential for the basic operation of the computer but are used to perform specific tasks and interact with the user.
10.
What would you use a USB Flash Drive for?
Correct Answer
A. Saving Files
Explanation
A USB flash drive is a portable storage device that can be used to save files. It allows users to transfer and store data, such as documents, photos, videos, and more. Unlike traditional storage options, like hard drives or CDs, a USB flash drive is small, lightweight, and easy to carry around. It provides a convenient way to backup important files, transfer data between devices, and access files on the go. Therefore, using a USB flash drive for saving files is a practical and common application.
11.
Which part of the computer system that one can physically touch?
Correct Answer
B. Hardware
Explanation
Hardware refers to the physical components of a computer system that can be touched, such as the monitor, keyboard, mouse, and CPU. Software, on the other hand, refers to the programs and applications that run on the hardware. The OS (Operating System) is a type of software that manages the computer's hardware and software resources. While programs are also a type of software that perform specific tasks. Therefore, out of the given options, only hardware can be physically touched.
12.
What are IC chips made of?
Correct Answer
A. Silicon
Explanation
IC chips, also known as integrated circuits, are made of silicon. Silicon is a semiconductor material that is widely used in the electronics industry due to its ability to conduct electricity under certain conditions. It is a crucial component in the manufacturing of IC chips as it allows for the miniaturization and integration of various electronic components onto a single chip. Silicon's properties, such as its high melting point, low electrical resistance, and ability to handle high temperatures, make it an ideal material for IC chip production.
13.
Which is not an Operating System?
Correct Answer
A. Microsoft Office XP
Explanation
Microsoft Office XP is not an operating system. It is a suite of productivity applications developed by Microsoft. Operating systems, on the other hand, are software that manage computer hardware and software resources and provide services for computer programs. Examples of operating systems include Red Hat Linux, BSD Unix, and Windows 98.
14.
1 GB is equal to
Correct Answer
A. 1024 MB
Explanation
1 GB is equal to 1024 MB. This is because in the binary system, each unit is multiplied by 2. So, 1 GB is equal to 2^10 MB, which is 1024 MB.
15.
Which of the following is an example of non-volatile memory?
Correct Answer
A. ROM
Explanation
ROM (Read-Only Memory) is an example of non-volatile memory. Non-volatile memory retains its data even when the power is turned off, and ROM is a type of memory that stores permanent instructions that cannot be altered or erased. Unlike RAM (Random Access Memory) and cache memory, which are volatile and lose their data when the power is turned off, ROM is non-volatile and its data remains intact. Therefore, ROM is the correct answer as an example of non-volatile memory.
