What is binary number system? Why is it used in computer system?
Answer:
Computers depend mainly on binary because it’s more time efficient for them to so.
Explanation:
It’s easier to identify 0 as “off” and 1 as “on”. As you may know, transistors are the fundamental blocks of microprocessors and ICs. The reasons this is the case is that these transistors form logic gates which can carry out basic logic operations. These logic gates are a huge step into making microprocessors/ICs/etc. And what do these logic gates depend on? They depend on binary.
Whoa whoa, wait a minute. Let’s first take a step back to know a thing or two about logic gates.
These logic gate can be constructed from transistors. They carry basic logic operations. You have one or more inputs “entering” the logic gate ——-> A certain operation is performed on them ——-> you get your output. The input is a voltage. This voltage it can be interpreted as an “on” or “off” according to the gate. Once again these offs and ons are 0s and 1s. For example the Inverter/NOT gate is a gate that simply takes an input and gives its inverse. For example:-
A low voltage/an “off” signal/ a “0” “enters” the NOT gate. ——-> A high voltage/an “on” signal/ a “1” is the result of the operation performed
(In the above example low voltage = “off” signal = 0, high voltage = “on” signal = 1)
As you can see, a 0 enters the NOT gate and a 1 comes out or vice versa. Now, if you were a logic gate, you’d prefer working with just 0s and 1s right? I would. This would be much easier to work with than a lot of different values.
It’s a herculean task to work with these though as a human. And fortunately, programming languages exist for giving the computer instructions to do in a “language” other than its own.

Answer:
computer system that connects computers of all sizes, workstations, terminals, and other devices within a limited proximity.
Explanation:
A local area network (LAN) refers to a group of personal computers (PCs) or terminals that are located within the same general area and connected by a common network cable (communication circuit), so that they can exchange information from one node of the network to another. A local area network (LAN) is typically used in small or limited areas such as a set of rooms, a single building, school, hospital, or a set of well-connected buildings. Some of the network devices or equipments used in a local area network (LAN) includes an access point, personal computers, a switch, a router, printer, etc.
Typically, a local area network (LAN) is best described as a computer system that connects computers of all sizes, workstations, terminals, and other devices such as switches, routers and access points (APs) within a limited proximity.
(Q003) The difference between a parameter and an exogenous variable is that Group of answer choices a parameter is allowed to change over time, while an exogenous variable is fixed over time. a parameter is an outcome of the model, while an exogenous variable is an input to the model. a parameter is an input to the model, while an exogenous variable is an output of the model. a parameter is fixed over time, while an exogenous variable is allowed to change over time.
Answer:
a parameter is fixed over time, while an exogenous variable is allowed to change over time.
Explanation:
A parameter can be defined as a value that can be passed to a function. Thus, a parameter refers to a value that must be passed into a function, subroutine or procedure when it is called.
This value can be passed to a function either by reference or by value.
Basically, parameters can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function.
A variable can be defined as a placeholder or container for holding a piece of information that can be modified or edited. Thus, a variable stores information which is passed from the location of the method call directly to the method that is called by the program.
An exogenous variable can be defined as a that's independent of other variables in a system i.e it's not affected by other variables.
This ultimately implies that, the difference between a parameter and an exogenous variable is that a parameter is fixed over time, while an exogenous variable is allowed to change over time and as such it has a relationship with other variables in a system.

What is the device that converts the signals to and from the wires so that the data can be sent and received by the computer?
A
domain name system
B
network
C
router
D
IP address
Answer:
E. Modem
Explanation:
A network comprises of two or more interconnected devices such as computers, routers, switches, smartphones, tablets, etc. These interconnected devices avail users the ability to communicate and share documents with one another over the network.
In order for a network to exist or be established, the devices must be turned (powered) on and interconnected either wirelessly or through a cable (wired) connection.
In Computer Networking, a node is the physical device that make up a network and are capable of sending, receiving, creating and storing data in communication.
Examples of network nodes are routers, hubs, computer, switches, smartphone, printers, modem, etc.
A modem is a networking device that converts the signals to and from the wires such as a telephone line, so that the data can be sent and received by the computer.
Basically, a modem is an abbreviation for modulator and demodulator and as such it is designed to convert signal from one network device to signals that another network device such as a computer can understand or read.
When sending a signal (data) over a network, a modem converts (modulate) digital data signal to an analogue signal and transmits it over a telephone line or other communication lines. Also, when receiving an analogue signal, a modem converts (demodulate) the signal to a digital data signal.

You've just deployed a new Cisco router that connects several network segments in your organization. The router is physically located in a server room that requires an ID card to gain access. You've backed up the router configuration to a remote location in an encrypted file. You access the router configuration interface from your notebook computer by connecting it to the console port on the router. You've configured the management interface with a username of admin and a password of password. What should you do to increase the security of this device
Answer:
Change the default administrative user name and password.Use an SSH client to access the router configuration.Explanation:
Remember, we are told the default username and password were simply, "admin" and "password". From a security perspective, both the password and username are weak choices. Hence, to increase the security of the notebook computer where the router configuration management interface is found, it is best you change the password.
Next, by using a Secure Shell Protocol (SSH) client to access the router configuration, the security is enhanced considering the fact the new Cisco router would connect several network segments in the organization.
