FREE ICT General Knowledge Questions and Answers
What is used to make IC chips?
Silicon is used to make integrated circuits, or IC chips. Because of its capacity to carry electricity under specific circumstances, silicon is a semiconductor material that is frequently utilized in the electronics sector. Because it enables the integration and downsizing of multiple electrical components onto a single chip, it is an essential component in the production of integrated circuits (ICs). Due to its high melting point, low electrical resistance, and tolerance for high temperatures, silicon is a perfect material for the manufacturing of integrated circuit chips.
A Universal Serial Bus: What Is It?
A common connection that enables items to be connected to a computer or other electronic device is the Universal Serial Bus (USB). It is a commonly used interface that links peripherals to computers, including printers, mouse, keyboards, and external storage devices. Most computers have USB connections, which are used to power and transport data to connected devices. Conversely, SATA and HDMI ports are distinct kinds of connectors that are employed for particular functions, including attaching storage devices or audio/video equipment, respectively. Because USB Port includes all of the previously described possibilities, it is the accurate response.
Which area of the computer system is accessible to the human touch?
The tangible parts of a computer system that can be touched, such as the CPU, keyboard, mouse, and display, are referred to as hardware. Programs and applications that operate on hardware are referred to as software, on the other hand. The software that controls the hardware and software resources of a computer is known as the operating system, or OS. Programs, on the other hand, are another kind of software that has specific functions. As a result, the only alternative that can be physically touched is hardware.
Which cable is used to attach a motherboard to a hard drive?
A hard disk and motherboard are connected via a SATA cable. Hard drives and solid-state drives are two typical types of storage devices that are connected to a computer's motherboard via SATA (Serial Advanced Technology Attachment), a form of data transfer interface. It offers a quick and dependable connection that enables high-speed data transfer between the motherboard and the hard disk. Older IDE (Integrated Drive Electronics) cables, which served a similar function but had slower data transfer rates, have been superseded by SATA cables. It is not common practice to attach hard drives to motherboards via USB or PS2 connectors.
A URL: What is it?
The acronym for Uniform Resource Locator is URL. To address and find resources on the internet, type this string of characters. It offers a means of locating and gaining access to particular files, including documents, photos, and web pages. The domain name (www.example.com), the protocol (http, https, ftp), and the precise path or location of the resource are the many parts that make up the URL. "Uniform Resource Locator" is the right response since it precisely describes what a URL is.
Peripheral gadgets include things like
The monitor, keyboard, and mouse are a few examples of peripheral devices, thus "all of the above" is the right response. External hardware components known as peripheral devices attach to a computer and increase its capability by enabling input and output. These accessories are used to carry out particular functions and communicate with the user; they are not necessary for the computer's fundamental functionality.
A keyboard falls under the category of ______.
Because it enables users to enter commands and data into computers and other electronic devices, keyboards are considered input devices. The computer recognizes and processes the letters, numbers, and symbols that the user types on the keyboard. Consequently, the purpose of a keyboard is to input data into a gadget.
With a USB flash drive, what would you do with it?
One type of portable storage that can be used to store files is a USB flash drive. Users can move and save a variety of data types, including documents, images, videos, and more. In contrast to conventional storage media such as CDs or hard drives, a USB flash drive is portable, lightweight, and easy to use. It offers a practical means of transferring data across devices, backing up crucial files, and accessing files while on the go. As a result, storing files on a USB flash drive is a useful and popular use.
RAM/DRAM: What is it?
Random Access Memory, or RAM for short, is a kind of computer memory that doesn't care where the data is physically stored; it can be read from and written to in any sequence. Because it is a volatile memory, when the power is switched off, the contents are gone. RAM serves as temporary storage for data and instructions that are being used by the CPU, making it a crucial part of any computer system. Fast data access makes effective multitasking and overall system performance possible.
A RAM or DRAM is which of these?
One kind of RAM (Random Access Memory) or DRAM (Dynamic Random Access Memory) is called DDR3 (Double Data Rate 3). This kind of memory is frequently seen in computers and other electronics. "DDR79-9-8" and "DRR3-PC2700," the other alternatives, do not correspond to legitimate RAM types.
Which of these operating systems is free?
Because Ubuntu is open source software, which allows anybody to read, alter, and distribute it without restriction, it is a free operating system. This gives customers the option to freely tweak and modify Ubuntu to suit their needs in addition to enabling them to use it without expense. Ubuntu is free to use and supports open-source software, in contrast to proprietary operating systems like Windows 7, Windows XP, and Mac OS X.
