Chapter 3 The Visible PC Key Term Quiz

Explanation
The correct answer is "vesa". VESA stands for Video Electronics Standards Association. It is an organization that sets standards for video display interfaces. The VESA standard includes the use of a 15-pin female DB connector to attach the monitor to the video card. This connector is commonly known as a VESA connector.

Explanation
Installing a DIMM stick in a computer increases the amount of RAM (Random Access Memory) available. RAM is a type of computer memory that is used to store data that is currently being used by the computer. By adding more RAM, the computer can handle larger amounts of data and run multiple programs more efficiently. This leads to improved performance and faster processing speeds.

Explanation
A CPU, or Central Processing Unit, is a component of a computer that performs most of the processing inside the computer. It has a make, which refers to the manufacturer or brand, a model, which specifies the specific version or type of CPU, a speed, which indicates the processing speed in terms of frequency, and a package, which refers to the physical form and layout of the CPU.

Explanation
The two RJ-11 connectors are used to identify the modem. RJ-11 connectors are commonly used for telephone connections, and in the context of this question, they are specifically referring to the connectors used for connecting a modem to a telephone line. Therefore, the presence of two RJ-11 connectors indicates that the device being referred to is a modem.

Explanation
When attaching a peripheral device, such as a printer or a keyboard, it is necessary to connect it to the appropriate port or jack on the computer. A port is a physical interface on a computer that allows for the connection of external devices. It serves as a point of entry or exit for data, allowing the peripheral to communicate with the computer. By plugging the device into the port, it establishes a connection and enables the transfer of data between the peripheral and the computer.

Explanation
The power supply is responsible for converting the standard electrical power from a wall outlet into a form that can be used by a computer. It ensures that the PC receives the correct voltage and current required for its operation. Without a power supply, the computer would not be able to function properly as it would not have the necessary power source.

Explanation
If an expansion card contains an RJ-45 jack, it is a RJ connector. The RJ-45 jack is a type of connector commonly used for Ethernet networking. It is specifically designed to connect networking cables, such as Ethernet cables, to devices such as computers, routers, and switches. Therefore, if an expansion card has an RJ-45 jack, it means that it is equipped with a RJ connector for networking purposes.

Explanation
A 25-pin female DB connector with a printer attached to it is a parallel port because parallel ports are commonly used to connect printers to computers. The 25-pin female DB connector is a standard connector for parallel ports, and it allows for the simultaneous transmission of multiple bits of data, hence the term "parallel." This type of port is commonly used for devices that require high-speed data transfer, such as printers, scanners, and external storage devices.

Explanation
An internal storage device that typically holds 200 GB or more is referred to as a hard drive. Hard drives are commonly used in computers to store large amounts of data and provide long-term storage capabilities. They are capable of holding a significant amount of data, making them suitable for various applications such as operating systems, software, and multimedia files.

Explanation
The system unit is the correct answer because it refers to the box that houses all the other components of a computer. It is where the motherboard, CPU, memory, and storage devices are located. The system unit is responsible for coordinating and managing all the operations of the computer.
