Explanation
The correct answer is 1024. This is because 1 GB is equal to 1024 kilobytes (KB). In computer systems, storage and memory are often measured in binary units, where each unit is a power of 2. Therefore, 1 GB is equal to 1024 MB, and 1 MB is equal to 1024 KB.

Explanation
The correct answer is PROM, EPROM, EEPROM. PROM stands for Programmable Read-Only Memory, which can be programmed once and retains its data even when power is turned off. EPROM stands for Erasable Programmable Read-Only Memory, which can be erased and reprogrammed using ultraviolet light. EEPROM stands for Electrically Erasable Programmable Read-Only Memory, which can be erased and reprogrammed electronically. These types of ROM provide different levels of flexibility in terms of programming and reprogramming, making them useful in various applications.

Explanation
Computers understand binary language. Binary language consists of only two digits, 0 and 1, which represent the off and on states of electrical signals within the computer's hardware. This language is the foundation of all digital computing systems and is used by computers to process and store information. By using combinations of these two digits, computers can represent and manipulate data, perform calculations, and execute instructions.

Explanation
The smallest measurement of memory is a bit. A bit is the basic unit of information in computing and can have a value of either 0 or 1. It represents the most fundamental level of data storage and is used to measure the amount of information that can be stored or transmitted. Other units of memory, such as kilobytes (KB), megabytes (MB), gigabytes (GB), and terabytes (TB), are all larger measurements that contain multiple bits.

Explanation
A joystick is the pointing device commonly used to play games. It allows for more precise control and movement compared to a mouse. With a joystick, players can easily navigate through game environments, perform complex maneuvers, and have a more immersive gaming experience. The other options, mouse and light pen, are not specifically designed for gaming purposes and may not provide the same level of control and functionality as a joystick.
