Проверенное решение:
Here are the answers to the questions based on the provided text:
-
The functional units of a digital computer are divided into three main components: storage units (primary and secondary), central processing unit (CPU), and input and output units.
-
The central processing unit (CPU) is composed of various components responsible for processing data and executing instructions, such as the arithmetic and logic unit (ALU) and the control unit.
-
The computer system is organized in a specific sequence: it begins with the functions of primary and secondary storage units, followed by the central processing unit (CPU), and finally, the input and output units.
-
The two primary types of storage units are primary storage and secondary storage.
-
Primary storage contains data, intermediate results of processing, final results of processing, and all the instructions required for ongoing processes. Secondary storage is not explicitly mentioned in the text.
-
The primary function of primary storage, also called memory, is to hold and store all data to be processed, intermediate results, final results, and the necessary processing instructions.
-
Primary storage is often referred to as memory due to its similarity to human memory, which stores information. However, computer memory differs from human memory in its capacity and the way it retains and retrieves information.
-
Computer memory differs from human memory in that it can retain a vast amount of symbol combinations (coded data) without forgetting or altering any details. It can also quickly locate its contents upon demand.
-
The codes used in computer design are based on a binary number system, which consists of only two possible values: 0 and 1. Each binary digit is called a bit, and combinations of bits are called binary codes. An 8-bit code is commonly used in computer design to represent all the characters used in communication.
-
Secondary storage refers to storage units that are slower and less expensive than primary storage. They are used to store large amounts of data and make this data available to the main storage (primary storage) as needed.
Please note that the text did not provide explicit information about secondary storage, so some details about it are missing in the answers.
Sure, I can provide brief answers to these questions:
The functional units of a digital computer include the central processing unit (CPU), memory, input devices, output devices, and storage devices.
The central processing unit (CPU) comprises the arithmetic logic unit (ALU) and the control unit.
The computer system is organized with the CPU as the central component, connected to memory, input/output devices, and storage.
The two primary types of storage units are primary storage (or RAM) and secondary storage (or storage drives).
Primary storage contains data and instructions that are actively being used by the CPU.
The primary function of primary storage is to provide fast access to data and instructions needed by the CPU during program execution.
Primary storage is often referred to as memory because it stores data temporarily for quick access by the CPU.
Computer memory differs from human memory in that it’s electronic and can store and retrieve data at incredibly high speeds, while human memory is biological and has limitations.
The codes used in computer design are based on binary code, which represents information using combinations of 0s and 1s.
Secondary storage refers to long-term storage devices like hard drives and SSDs used to store data when the computer is turned off or for archiving purposes.
