Please fill answer below_______
Explanation
Sputnik was the first artificial satellite put into orbit, launched by the Soviet Union during the Cold War.

The "brains" of a computer, called the _______________, is a very complex, interconnected set of electronic devices, processor, memory, and control chips.
Explanation
The motherboard is considered the "brains" of a computer because it houses all the essential components necessary for the computer to function. It connects and allows communication between the processor, memory, and control chips, enabling them to work together seamlessly. Without the motherboard, these components would not be able to interact and perform their respective tasks effectively, making it a crucial component in the overall functioning of a computer system.

________________ conduct currents, but not as well as a true conductor, such as copper.
Explanation
Semiconductors are materials that have properties in between those of conductors and insulators. They can conduct electricity, but not as effectively as true conductors like copper. Semiconductors have a lower conductivity due to their energy band structure, which allows them to conduct currents under certain conditions. They are widely used in electronic devices and technology, as their conductivity can be controlled and manipulated to create different functionalities. Therefore, the given answer options all refer to materials that can conduct currents to some extent, but not as well as copper or other true conductors.

An ___________ signal ranges over a continuous set of values.
Explanation
An analog signal is a type of signal that varies continuously over a range of values. Unlike a digital signal, which is discrete and can only take on specific values, an analog signal can have any value within its range. This allows for more precise and nuanced representations of data.
11.
A _____________ signal has a discrete limited set of numerical values such as bits and bytes.
Explanation
A digital signal is a type of signal that uses a discrete limited set of numerical values, such as bits and bytes, to represent information. Unlike analog signals, which can have an infinite range of values, digital signals are characterized by their specific and finite numerical values. This makes digital signals more reliable and less susceptible to noise and interference compared to analog signals. Therefore, the correct answer is "digital" or "digital signal".
12.
Discrete packets of information that contain any type of data coded in digital form are called ___________.
Explanation
Data packets are discrete units of information that are coded in digital form. They can contain any type of data, such as text, images, or audio. These packets are used to transmit data over networks, where they are broken down into smaller units and then reassembled at the receiving end. Data packets ensure efficient and reliable transmission of data by allowing for error detection and correction. They also enable the simultaneous transmission of multiple streams of data, improving network performance. Therefore, the correct term for discrete packets of information coded in digital form is data packets.
13.
Every computer on the internet must have an IP, or ________________, address.
Explanation
Every computer on the internet must have an IP address. The IP address is a unique identifier assigned to each device connected to a network. It allows computers to communicate with each other and enables the routing of data packets across the internet. The term "internet protocol" refers to the set of rules and protocols that govern the format and transmission of data over the internet. Therefore, the correct answer to the question is "internet protocol."
14.
In addition to carrying the address of the receiving computer, each data packet also has to have a ______________ so that the receiving computer can reassemble the message in the correct order.
Explanation
Each data packet needs a sequence number so that the receiving computer can arrange the packets in the correct order. This is important because data packets can be transmitted out of order or take different paths through a network. By including a sequence number, the receiving computer can identify the correct order of the packets and reassemble the message accurately.

Small computer groups are called LAN, or ___________________ , and can still be hacked.
Explanation
Small computer groups are called LAN, or local area connections/ local area connection, and can still be hacked. A LAN refers to a network of computers and devices that are connected within a limited geographical area, such as an office building or a school campus. Despite being smaller in scale compared to wide area networks (WANs), LANs are still susceptible to hacking attempts. This is because any network, regardless of its size, can be targeted by cybercriminals seeking to exploit vulnerabilities and gain unauthorized access to sensitive information or disrupt operations.
