Ev Itf Unit 2 Test

Explanation
The computers were classified based on their capability. This means that they were categorized according to their performance, features, and functionalities. This classification allows for a better understanding of the different types of computers available, as it helps identify their specific uses and limitations. By classifying computers based on their capability, it becomes easier to compare and choose the most suitable option for specific needs or requirements.

Explanation
A supercomputer typically has multiple microprocessors, which are the central processing units (CPUs) responsible for executing instructions and performing calculations. These multiple microprocessors work together in parallel to handle complex computational tasks more efficiently and quickly. By distributing the workload among multiple processors, a supercomputer can achieve high processing speeds and handle massive amounts of data simultaneously. Therefore, the answer is "Yes," a supercomputer does have more than one microprocessor.

Explanation
A small Mom and Pop store might not use a mainframe computer because they typically have limited resources and may not require the complex computing power that a mainframe offers. Mainframes are typically used by large organizations like banks and corporations to handle massive amounts of data and perform complex calculations. In contrast, a small Mom and Pop store may only need basic computer systems for tasks like inventory management and sales tracking, which can be easily handled by smaller, more affordable computers.

Explanation
Servers are the type of computers used to house email networks. Servers are specifically designed to handle and manage large amounts of data and perform tasks such as storing, sending, and receiving emails. They are equipped with powerful processors, large storage capacities, and high-speed internet connections to efficiently handle the demands of email networks. Supercomputers are used for complex scientific calculations, while desktops are typically used for personal computing tasks. Therefore, servers are the most suitable type of computers for housing email networks.

Explanation
The question asks for something that is not an example of a mobile computer. Both the iPhone and laptops are examples of mobile computers as they are portable and can be used on the go. However, a desktop computer is not portable and is typically used in a fixed location, making it not an example of a mobile computer.

Explanation
Windows Vista is not an example of hardware because it is an operating system software developed by Microsoft. Hardware refers to physical components of a computer system, such as a monitor and microprocessor, that can be touched and interacted with.

Explanation
A mouse is a hardware device used to interact with a computer, whereas Word and Internet Explorer are software applications. Therefore, the mouse is not an example of software.

Explanation
The question asks for a hardware component that was not studied. While memory, storage, processor, inputs, and outputs are all essential hardware components, software is not a hardware component but rather a program or set of instructions that runs on the hardware. Therefore, software is the correct answer as it does not fall under the category of essential hardware components studied.

Explanation
The journey that inputs take to become outputs is known as the system bus. The system bus is responsible for transferring data and instructions between the various components of a computer system, such as the CPU, memory, and input/output devices. It acts as a communication pathway, allowing data to flow between different parts of the system and enabling the processing of inputs to produce outputs.

Explanation
A printer is not an input device because it is used to produce a physical copy of data or information from a computer. Input devices, on the other hand, are used to provide data or instructions to a computer. The modem, mouse, and keyboard are all examples of input devices as they allow the user to input data or commands into the computer system.

Explanation
The keyboard is not an example of an output because it is an input device. It allows the user to input data or commands into a computer system by pressing keys. In contrast, a monitor is an output device that displays visual information, and a modem is used to transmit data from one computer to another.

Explanation
RAM (Random Access Memory) and ROM (Read-Only Memory) are both types of computer memory, but they have different characteristics. RAM is considered short-term memory because it stores data that is actively being used by the computer. It is volatile, meaning that its contents are lost when the power is turned off. On the other hand, ROM is considered longer-term memory because it stores data that is permanently written during manufacturing and cannot be modified or erased by normal computer operations. ROM is non-volatile, meaning that its contents are retained even when the power is turned off. Therefore, the main difference between RAM and ROM is their storage capabilities and the duration for which the data is retained.

Explanation
RAM stands for Random Access Memory. It is a type of computer memory that allows data to be stored and retrieved quickly by the computer's processor. Unlike other types of memory, such as hard drives or solid-state drives, RAM is volatile, meaning that its contents are lost when the computer is powered off. Random access refers to the ability to access any memory location directly, without having to sequentially read through the entire memory. Therefore, the correct answer is Random Access Memory.

Explanation
Storage on iPods is measured in gigabytes. Gigabytes is a unit of digital information storage that represents billions of bytes. It is commonly used to measure the capacity of storage devices, including iPods. Terabytes, on the other hand, represent a larger unit of storage capacity and are typically used for measuring larger storage systems such as hard drives or servers. Therefore, gigabytes is the correct answer for measuring storage on iPods.

Explanation
A port refers to the point of connection on a computer where inputs and outputs are connected. It acts as a gateway for devices such as keyboards, mice, printers, and external storage devices to communicate with the computer. This allows data to be transferred between the computer and external devices, enabling the user to interact with the computer and exchange information. The engine of the computer, on the other hand, typically refers to the central processing unit (CPU) which performs calculations and executes instructions.
