RAM is also called ____.

ROM
Flash memory
Main memory
Cache

Correct Answer

A. Main memory

Explanation

RAM stands for Random Access Memory, which is a type of computer memory that can be accessed randomly, meaning any byte of memory can be accessed without touching the preceding bytes. It is also known as main memory because it is the primary memory used by the computer to store data that is actively being used by the CPU. ROM (Read-Only Memory) is a type of memory that stores data permanently and cannot be modified. Flash memory is a type of non-volatile memory used in devices like USB drives and memory cards. Cache is a smaller, faster memory used to temporarily store frequently accessed data for quicker access.

To attach multiple peripherals using a single USB port, you can use a(n) ____.

Daisy link
USB hub
Network
array

Correct Answer

A. USB hub

Explanation

A USB hub is a device that allows you to connect multiple peripherals to a single USB port. It acts as a central hub, expanding the number of available USB ports and allowing you to connect devices such as keyboards, mice, printers, and external storage devices. By using a USB hub, you can easily connect and use multiple peripherals simultaneously without the need for additional USB ports on your computer.

One type of processor, called ____, integrates the functions of a processor, memory, and a video card on a single chip.

Microprocessor
Power processor
System on a chip
Multimedia processor

Correct Answer

A. Multimedia processor

Explanation

A multimedia processor is a type of processor that combines the functions of a processor, memory, and a video card on a single chip. This integration allows for efficient and high-performance processing of multimedia tasks such as video playback, image processing, and graphics rendering. By having all these functions on a single chip, it eliminates the need for separate components and improves overall system performance and power efficiency.

A(n) ____ is a device that connects to the system unit and is controlled by the processor in the computer.

Expansion card
Peripheral
Connection card
Chip card

Correct Answer

A. Peripheral

Explanation

A peripheral is a device that connects to the system unit and is controlled by the processor in the computer. It is an external device that provides additional functionalities to the computer system, such as input, output, or storage capabilities. Examples of peripherals include keyboards, mice, printers, scanners, and external hard drives. These devices are connected to the computer through various ports or wireless connections and allow the user to interact with the computer system.

Each byte resides temporarily in a location in memory that has a(n) ____.

Address
Port
Slot
Pipe

Correct Answer

A. Address

Explanation

Each byte in memory is assigned a unique address, which is used to identify and locate the byte in memory. The address is like a physical location for the byte in memory, allowing the computer to access and manipulate the byte as needed.

A processor contains small, high-speed storage locations, called ____, that temporarily hold data and instructions.

Control units
Boards
Registers
Pointers

Correct Answer

A. Registers

Explanation

A processor contains small, high-speed storage locations called registers that temporarily hold data and instructions. These registers are used by the processor to perform various operations, such as arithmetic calculations, data manipulation, and control flow. They provide fast access to data and instructions, allowing the processor to quickly retrieve and store information during its execution. Registers are an essential component of a processor's architecture and play a crucial role in its overall performance and efficiency.

____ on the motherboard hold memory modules.

Drive bays
Memory slots
Expansion slots
Ports

Correct Answer

A. Memory slots

Explanation

Memory slots on the motherboard are designed to hold memory modules. These slots provide a connection between the memory modules and the motherboard, allowing the computer to access and store data in the memory. Memory slots are typically located near the CPU and are easily accessible for upgrading or replacing memory modules.

Bit is short for ____.

Binary data
Binary digit
Digital byte
Binary unit

Correct Answer

A. Binary digit

Explanation

Bit is short for "binary digit" because a bit is the basic unit of information in computing and digital communications. It represents a single binary value, either 0 or 1, and is the smallest unit of data that a computer can process. The term "bit" is derived from the words "binary" and "digit," indicating its connection to binary data and its representation as a single digit in the binary numbering system.

The most widely used coding system to represent data is the ____ scheme.

Infrared Data Association (IrDA)
Extended Binary Coded Decimal Interchange Code (EBCDIC)
American Standard Code for Information Interchange (ASCII)
Unicode

Correct Answer

A. American Standard Code for Information Interchange (ASCII)

Explanation

ASCII is the most widely used coding system to represent data. It is a character encoding scheme that represents text in computers and other devices. It uses a 7-bit code to represent characters, including letters, numbers, and special characters. ASCII is compatible with most modern computer systems and is used in a wide range of applications, including communication protocols, file formats, and programming languages. It is widely recognized and supported, making it the preferred choice for data representation.
