Answer: mainframe computer

Explanation:

Mainframe computer is a large and expensive computer capable of simultaneously processing data for hundreds or thousands of users.

Answer: crash

Explanation:

The correct answer is (a) crash. When a computer stops working suddenly or unexpectedly, it is referred to as a crash. A computer crash can be caused by various factors such as hardware failure, software errors, viruses, or overheating. When a crash occurs, the computer may freeze, display error messages, or shut down completely, making it unusable until the issue is resolved.

Answer: notebook computer

Explanation:

The correct answer is (a) notebook computer, which is also commonly referred to as a laptop. A notebook computer is a portable, personal computer that is small enough to be used on your lap or carried around with you. It typically has a keyboard, trackpad or pointing stick, and a display screen that folds down over the keyboard when not in use. Notebook computers are designed to be more portable than desktop computers, while still providing many of the same features and capabilities. Therefore, options (b), (c) and (d) are incorrect.

Answer: an operating system

Explanation:

All computers must have an operating system, which is the software that manages computer hardware and software resources and provides common services for computer programs.

Answer: Portable, light weight and fit into briefcases

Explanation:

Laptops are portable, lightweight computers that are designed to fit into briefcases or backpacks for easy transport. They are equipped with built-in batteries, displays, keyboards, and touchpads or pointing sticks, allowing users to work and communicate on the go. Laptops are commonly used for personal and professional computing tasks, such as word processing, web browsing, email, video conferencing, and multimedia playback. They are not specifically designed for use in chemical laboratories or with voice recognition systems, although they may be used for these purposes with appropriate software and peripherals.

Answer: individual

Explanation:

A personal computer is designed to meet the computing needs of an individual

Answer: server

Explanation:

The correct answer is (d) server.

Answer: contain thousands of microprocessors

Explanation:

Supercomputers are high-performance computing systems designed to perform complex calculations and data-intensive tasks. They are typically used for scientific and engineering applications, such as climate modeling, molecular dynamics simulations, and computational fluid dynamics. Supercomputers contain thousands of microprocessors working together in parallel to perform calculations at a much faster rate than traditional computers. They are not smaller than mainframe computers and are not commonly found in households. They are also not of the same size as laptops, as they require specialized cooling and power systems.

Answer: Both sequentially and parallel

Explanation:

The correct answer is (c) Both sequentially and parallel. Latest generation computers use a combination of sequential and parallel processing to execute instructions. This is because some tasks can be broken down into smaller, independent tasks that can be executed simultaneously by different processing units, while other tasks require a specific sequence of instructions to be executed in order to achieve the desired outcome. Modern computer architectures, such as multicore processors and graphics processing units (GPUs), are designed to support both sequential and parallel processing, allowing them to handle a wide range of tasks efficiently. Therefore, options (a), (b) and (d) are all incorrect.

Answer: Fourth Generation

Explanation:

As thousands of integrated circuits were packed into a single silicon chip, the microprocessor ushered in the fourth generation of computers.
