An IP address is a unique number consisting of 4 parts separated by dots that is associated with every system connected to a network. This address allows devices to communicate with each other over the internet. It serves as a unique identifier for each device, similar to a phone number, allowing data to be sent and received accurately.

The correct answer is 1024KB because in the binary system, 1 kilobyte (KB) is equal to 1024 bytes. Therefore, one megabyte (MB) is equal to 1024KB.

Ping is a computer network tool used to test the reachability of a host across an IP network. It sends a small packet of data to the host and waits for a response. If the host responds, it indicates that it is reachable. Ping is also used to self-test the Network Interface Card (NIC) of the computer, ensuring that it is functioning properly. Therefore, the correct answer describes the purpose and functionality of Ping accurately.

Malware is best defined as software designed to infiltrate or damage a computer system without the owner's informed consent. This type of software is specifically created to exploit vulnerabilities in a computer system and can cause various types of harm, such as stealing sensitive information, disrupting system operations, or allowing unauthorized access to the system. It is important to distinguish malware from antivirus software, which is designed to protect the operating system from viruses. The other options provided in the question are not accurate definitions of malware.

An output device is a device that is used to display or transmit data or information from a computer system. A printer is an output device that produces a hard copy of the data, a monitor is an output device that displays visual information, and a modem is a device that connects a computer to the internet.

A network interface card (NIC) is a computer component that allows a computer to connect to a network. It provides the necessary hardware to establish a wired or wireless connection to a local area network (LAN) or a wide area network (WAN). The NIC is responsible for transmitting and receiving data packets over the network, enabling communication between the computer and other devices or computers on the network. It is an essential component for accessing the internet, sharing files, and connecting to other devices in a network.

The CPU, or Central Processing Unit, is the component responsible for executing instructions and performing calculations in a computer. It is often referred to as the "brain" of the computer. The CPU processes data and controls the overall operation of the system. It is an essential component that determines the speed and performance of a computer.

The correct answer is that the device is used to store large amounts of data in a computer system, and the data is retained on this device even when the computer is turned off. This suggests that the device being referred to is a secondary storage device, such as a hard disk drive or solid-state drive, which is used to store data for long-term use. These devices have larger storage capacities compared to the other options mentioned and are designed to retain data even when the power is turned off.

The correct answer is Chassis. A chassis is a computer component that houses and protects the internal hardware components of a computer. It provides structural support and helps in organizing the components in a secure manner. It also provides ports and connectors for external devices to be connected to the computer.

This question is asking for a measurement of speed over a network. The options given are Megabytes, Bits, Megahertz, and Megabits per second. Out of these options, Megabits per second is the most appropriate measurement for network speed. Megabytes refers to the size of data, not the speed. Bits and Megahertz are also not specifically used to measure network speed. Therefore, Megabits per second is the correct answer as it is commonly used to quantify the speed of data transmission over a network.

Bandwidth refers to the measurement of how much information can be carried in a given time period, typically a second, over a wired or wireless communications link. It represents the capacity or speed at which data can be transferred from a server to a client. This measurement is crucial in determining the efficiency and speed of data transmission in networks. The other options mentioned, such as the speed of data transfer or a unit of computer storage, are not accurate definitions of bandwidth.

The correct answer is untitled.jpg, untitled.bmp, and untitled.tiff because these three file extensions (.jpg, .bmp, .tiff) are commonly used for graphics files. The other options (.nfo and .ogg) are not typically associated with graphics files.

The correct answer is the US Department of Defense. The internet was originally developed by the US Department of Defense in the late 1960s as a means of communication and sharing information between different computers. It was initially known as ARPANET and was primarily used by the military and academic institutions. Over time, the internet evolved and expanded to become the global network that we know today.

The term Operating System refers to the software that allows computer users to run applications with the hardware of a specific system.
