2. Fill in the blank:
In order for a computer to function, it is required to have which of the following.

Usb port

Printer ports

CD ROM

Operating system

Speakers

An operating system is required for a computer to function because it acts as the intermediary between the hardware and software. It manages the computer's resources, controls the execution of programs, and provides a user interface. Without an operating system, the computer would not be able to perform tasks, run applications, or interact with the user effectively.

3. The brain of the computer is often referred to as

RAM Read Access Memory

Head Monitor

CPU Central Processing unit

ROM Read Only Memory

None of the above

The brain of the computer is often referred to as the CPU or Central Processing Unit. The CPU is responsible for executing instructions, performing calculations, and managing the flow of data within the computer. It is considered the most important component of a computer system as it controls and coordinates all the other hardware and software components. RAM, ROM, and the head monitor are all important components of a computer, but they do not perform the same level of processing and control as the CPU.

4. A megabyte is equivalent to which of the following

1 GB

1000 bytes

1024 kilobytes

1 million bytes

None of the above

A megabyte is equivalent to 1024 kilobytes because in the binary system, each kilobyte is equal to 1024 bytes, and since a megabyte is 1024 times larger than a kilobyte, it would be equal to 1024 kilobytes.

5. Which of the following item(s) are not considered input device(s).

Mouse

Keyboard

Printer

Monitor

Speakers

The printer, monitor, and speakers are not considered input devices because they are used to output information rather than inputting data. A printer is used to produce hard copies of documents, a monitor displays visual output, and speakers produce audio output. In contrast, a mouse and keyboard are input devices as they allow the user to input data and commands into the computer.

6. Identify which of the following a computer port is used for, more than one answer applies

Emailing from one source to another

Download data from the internet

Plug in a speaker

Allow access to another person's c drive

Connect two computers

A computer port is used for multiple purposes, including emailing from one source to another, downloading data from the internet, and connecting two computers. Computer ports provide the necessary interface for communication and transfer of data between devices. They allow for the exchange of information, whether it be through email or downloading data, and facilitate connections between computers for various purposes such as file sharing or networking.
