Information Technology Quiz Form#1

The correct answer is "a set of instructions that a computer needs to carry out its task." This answer accurately describes software as a collection of instructions that are necessary for a computer to perform its intended functions or tasks. Software provides the necessary guidance and commands to the computer's hardware components, enabling it to execute specific operations and tasks as desired by the user.

The correct answer is "a programmable electronic device that processes data following a set of instructions." This answer accurately describes a computer as a device that can be programmed to perform tasks and process data based on a predetermined set of instructions.

The statement is true because storage in a computer allows users to save information and retrieve it later. This can be done through various storage devices such as hard drives, solid-state drives, and cloud storage. By storing data, users can access it at a later time and use the information as needed.

The correct answer is "All the part of the computer system u can see and touch." This answer accurately describes hardware as the physical components of a computer system that can be seen and touched. It distinguishes hardware from software, which refers to the programs and instructions that run on the hardware.

The main memory is indeed also known as the primary storage. It is a type of computer memory that is directly accessible to the CPU and is used to store data that is currently being processed by the computer. It is called primary storage because it is the main storage location that the CPU can access quickly.

Data refers to the basic facts and figures that a computer processes. It is processed by following a set of instructions called a program. Data can be in various forms such as numbers, text, images, or videos. It is the raw material that is used to generate information.

A personal computer (PC) is a type of computer that is designed to be used by one person at a time and is typically small enough to fit on a desk. It is different from a mainframe computer, which is typically larger and designed to be used by multiple users simultaneously. The correct answer explains that a personal computer is designed for individual use and can be conveniently placed on a desk.

Processing data to get information involves three stages. The first stage is data input, where raw data is collected and entered into a system. The second stage is data processing, where the collected data is organized, manipulated, and analyzed to extract meaningful information. The final stage is data output, where the processed information is presented in a format that is useful and understandable to the user. These three stages are essential in the data-to-information transformation process.

In 1971, the microprocessor chip was developed. This technological advancement revolutionized the field of computing by integrating the central processing unit (CPU) onto a single chip. The microprocessor chip allowed for faster and more efficient processing of data, leading to the development of smaller and more powerful computers. This breakthrough paved the way for the modern era of computing and has had a profound impact on various industries and everyday life.

The correct answer is 1982. This suggests that the first portable computer was developed in 1982.
