How software, hardware, and networks work — explained plainly with practical examples.
9 explained questions, each with the answer, a worked explanation, and something interactive to help it stick.
- How do you open a program when there are no icons on the desktop?Click the Start button (the Start menu) in the corner of the taskbar. It lists every installed app even when the desktop has no icons. You can also use Windows Search, the Run box (Win+R), or File Explorer to launch programs.Read the guide
- Which of the following best explains what happens when a new device is connected to the internet?When a new device connects to the internet, it is assigned an Internet Protocol (IP) address, usually automatically by a DHCP server. This address uniquely identifies the device on the network so it can send and receive data.Read the guide
- What is the bitrate of a system?Bitrate is the amount of data, in bits, that a system can transmit or process in a fixed amount of time. It is measured in bits per second (bps), with larger units of kilobits (Kbps), megabits (Mbps), and gigabits (Gbps) per second.Read the guide
- Any computer parts that you can actually touch are considered to be what?Hardware. Any physical, tangible part of a computer that you can actually touch — such as the monitor, keyboard, mouse, motherboard, CPU, RAM, or hard drive — is called hardware. Software, by contrast, is the intangible programs, instructions, and code that run on the hardware.Read the guide
- What Does It Mean for a Routing System to Be "Redundant," and Is Redundancy Good or Bad?A redundant routing system has multiple, independent paths between any two points, so if a link or router fails, traffic automatically reroutes over a backup path. Redundancy is good: it greatly improves reliability and fault tolerance, at the cost of extra hardware, expense, and configuration complexity.Read the guide
- What Does the Computer Term "Desktop" Refer To?In computing, the desktop is the main screen you see after the operating system boots and you log in. It displays your wallpaper along with icons for folders, files, and applications, acting as your primary workspace. The word can also describe a non-portable desktop computer.Read the guide
- What Program Command Saves a Copy of a File Under a Different Name?The "Save As" command saves a copy of the current file under a new name or in a new location without changing the original. Plain "Save" overwrites the original, while "Copy" and "Duplicate" work differently — so "Save As" is the correct answer.Read the guide
- Which of the Following Is Accurate Regarding Conventions for File Naming?The accurate statement is that good file names avoid spaces and special characters (use underscores or hyphens), use ISO 8601 dates (YYYY-MM-DD), place the most important information first, apply leading zeros for numbering, and stay short but descriptive.Read the guide
- What Is Required to Access Dynamic Study Modules?You need a registered Pearson MyLab or Mastering account with an active, enrolled course. You must first launch a Dynamic Study Module on a computer (via a web browser) before the mobile app can sync to your account. Self-study users with no course enrollment do not get access.Read the guide
