Test Hardware

The correct answer is "placa de bază" (motherboard). The motherboard is the main circuit board in a computer that connects and allows communication between all internal hardware components, such as the CPU, RAM, storage devices, and expansion cards. It provides the necessary electrical connections and interfaces for these components to work together and enables the computer to function as a whole.

ROM stands for Read-Only Memory, which is a type of non-volatile memory that stores data permanently. Unlike RAM (Random Access Memory), ROM cannot be modified or erased. It contains firmware or software instructions that are permanently programmed during manufacturing and cannot be changed by normal computer operations. ROM is commonly used to store the computer's BIOS (Basic Input/Output System), which is responsible for booting up the system and initializing hardware components. Therefore, ROM is a type of internal memory that retains data even when the power is turned off, making it an appropriate answer in this context.

Two bytes are equivalent to 16 bits. In computer systems, a byte is a unit of digital information that consists of 8 bits. Therefore, if we have two bytes, we can calculate the total number of bits by multiplying 8 (bits in a byte) by 2 (number of bytes), which equals 16 bits.

The correct answer is "de intrare" because a scanner is a device that is used to input physical documents or images into a computer system. It allows the user to scan and convert physical documents into digital format, which can then be stored or manipulated on a computer. Therefore, a scanner is considered an input device as it allows information to be inputted into the computer system.

The correct answer is "procesorul" (the processor). The processor is responsible for performing arithmetic and logical calculations in a computer system. It is the central component that executes instructions and processes data, making it the device that carries out arithmetic and logical operations. The hard disk, RAM, and motherboard are important components in a computer system, but they do not directly perform arithmetic and logical calculations like the processor does.

The correct answer is 1024KB=1MB. This is because in computer science, the binary system is used for storage measurement. In this system, 1 kilobyte (KB) is equal to 1024 bytes, and 1 megabyte (MB) is equal to 1024 kilobytes. Therefore, 1024KB is equal to 1MB.

The correct answer is byte. Byte is the unit of measurement for data storage in a computer's memory. It is a group of 8 bits, and each byte can represent a single character or a small amount of numerical data. When data is stored or retrieved from the computer's memory, it is done at the byte level.

The correct answer for this question is "UCC, unitatea de comanda si control". The Unitatea Aritmetică și Logică (Arithmetic and Logic Unit) is one of the components of the Unitatea Centrală de Prelucrare (Central Processing Unit). Along with the UCC, which stands for "unitatea de comanda si control" (control and command unit), these components work together to perform calculations and logical operations in a computer system.

The components that cannot be missing from the minimum configuration of a functional PC are the processor, memory, motherboard, and keyboard. These components are essential for the basic functioning of a computer. The processor is responsible for carrying out all the calculations and operations, while the memory stores data and instructions for the processor to access. The motherboard connects all the components together and allows them to communicate with each other. The keyboard is necessary for inputting commands and interacting with the computer.
