Explanation

A GUI (Graphical User Interface) is a type of interface that allows users to interact with a computer system through visual elements such as icons, buttons, and menus. It provides a user-friendly way to navigate and operate a computer system. In this context, the statement is true because a GUI does indeed allow users to select words, symbols, or graphics from a desktop by simply clicking or tapping on them.

Submit
6. What does RAM stand for?

Explanation

RAM stands for Random Access Memory. It is a type of computer memory that allows data to be accessed randomly, meaning any byte of memory can be accessed without touching the preceding bytes. This allows for fast and efficient data storage and retrieval. 

Submit
7. Speakers allow you to save audio right to your hard drive.

Explanation

Speakers are output devices that produce sound, they do not have the capability to save audio to a hard drive. Saving audio to a hard drive requires a recording device such as a microphone or a software program that allows audio recording. Therefore, the statement is false.

Submit
8. The CPU is a single chip called a microprocessor.

Explanation

The statement is true because the CPU (Central Processing Unit) is indeed a single chip known as a microprocessor. The microprocessor is responsible for executing instructions and performing calculations in a computer system. It acts as the brain of the computer, handling all the processing tasks.

Submit
9. What does CPU stand for

Explanation

The correct answer is "Central Processing Unit." CPU stands for Central Processing Unit, which is the primary component of a computer that performs most of the processing inside the computer. It carries out instructions of a computer program by performing basic arithmetic, logical, control, and input/output (I/O) operations. The other options, "Central Prosess unit" and "Central process unit," are misspellings of the correct term.

Submit
10. Data are stored permanently in RAM.

Explanation

The given statement is incorrect. Data is not stored permanently in RAM (Random Access Memory). RAM is a volatile memory where data is temporarily stored while the computer is running. Once the power is turned off, the data stored in RAM is lost. For permanent storage of data, other non-volatile storage devices like hard drives or solid-state drives are used.

Submit
11. Which of these is not an output device?

Explanation

A microphone is not an output device. It is an input device that converts sound into an electrical signal, which can then be processed and transmitted. Output devices, on the other hand, are used to display or produce information or results from a computer system. Examples of output devices include monitors, printers, and speakers, all of which are capable of displaying or producing visual or audio output.

Submit
12. What are the two most common operating systems?

Explanation

The two most common operating systems are Microsoft Windows and Macintosh OS. These operating systems are widely used and have a large user base. Microsoft Windows is the most popular operating system for personal computers, while Macintosh OS is the operating system used on Apple Macintosh computers. Both operating systems offer a wide range of features and applications, making them popular choices for users around the world.

Submit
13. Dial-up connections transmit data at a faster rate than broadband connections.

Explanation

This statement is false. Dial-up connections transmit data at a slower rate than broadband connections. Dial-up connections use a standard telephone line to connect to the internet, which has a maximum speed of 56 kilobits per second (Kbps). On the other hand, broadband connections use technologies like DSL, cable, or fiber-optic, which can provide much higher speeds ranging from several megabits per second (Mbps) to gigabits per second (Gbps). Therefore, broadband connections are generally faster than dial-up connections.

Submit
14. What special hardware device is used to join two or more LANs?

Explanation

A router is a special hardware device that is used to join two or more LANs (Local Area Networks). It acts as a central hub, directing network traffic between different LANs and ensuring that data packets are delivered to their intended destinations. Routers use routing tables to determine the most efficient path for data transmission, allowing multiple LANs to be interconnected and enabling communication between devices on different networks. Unlike other options listed, such as NIC (Network Interface Card), WAN (Wide Area Network), or modem, a router specifically serves the purpose of connecting LANs together.

Submit
15. Which of these is not an input device?

Explanation

A monitor is not an input device because it is used to display output from a computer rather than to input data or commands. Input devices are used to provide input to a computer system, such as a mouse, keyboard, scanner, or microphone. A monitor is an output device that allows users to visually see the output of their actions on the computer.

Submit
16. What connects computers in a single location to other computers at that location?

Explanation

LAN, or Local Area Network, is the correct answer because it connects computers in a single location to other computers at that location. A LAN is a network that is confined to a small geographical area, such as a home, office, or building, and allows computers and devices to share resources, such as files, printers, and internet access. It provides a means for computers within the same location to communicate and share information efficiently.
