Which Of The Following Ports Is Not Considered To Be Exclusively A Video Port?
The USB will not be considered to be exclusively the video port. Today, let us learn about the USB in detail and how the USB works.
The tern USB stands for universal serial bus. The USB is mainly introduced or created in order to improve the quality of its speed while transferring the data through all the serial ports.
The USB 2.0, here the 2.0 represents the version of the USB that can bale to operate up to 48 megabytes per second.
The next version of the USB is USB 3.0 that can able to offer 4.8 gigabytes per second. The USB 3.0 will be ten times faster than the other while transferring the data.
And in order to get that use, we just need to use the USB 3.0 port. While transmission of the data, the USB 3.0 will able to work bidirectionally. It represents that the connected devices will be able to send as well as can receive the data parallelly.
The USB 2.0 can only able to transfer the data at only a one percent rate when we compared it with the USB 3.0. The USB 3.0 will be able to transfer at a rate with high electrical power when we compared it with the USB 2. It means that the USB 3.0 can able to support up to 900 milliamps at the rate of 5 volts, it represents that the 3.0 can able to feed that can able to consume more of the energy. This is such as the drives that are using the version of USB 2.0.
The USB 2.0 will always require its own dedicated power for itself and it can able to supply more power that is faster than the USB 3.1 version.
The version USB 3.1 can able to transfer the data at a rate of up to 10 gigabytes per second. We also use the other type of 3.1 connectors, this is nothing but the type C USB connector.
This type C USB connector will be injected into the USB port without any of the regards. Here we do not need to look at any of those before we need them to plug into the USB port type.
Here the main advantage of the universal serial bus (USB) is that it can able to support the power that is up to 100 watts. These 100 watts of power can be normally used in order to recharge its batteries.
Here it can able to recharge its battery to the entire computer. And also the type C cables have the capability in order to stream the videos.
Type C can also be able to perform input and the output single cables which can able to transmit the video cell from a cell phone to any of the other computer devices or it can be from a phone to the television device. This type of technology has a special name called backward technology.

What Are Two Functions That Are Provided By The Network Layer? (Choose two.)
Firstly, the network layer provides the unique network identifier which is provided through its end devices. And the second most important function of the network layer is that it can directly transfer the data into the destination address. The data is transferred in the form of the data packets to the other side of the network.
Today, let us discuss what actually the network layer is and the functions of the network layer. Here, the main important function of the network layer is that the network layer can able to provide the host to host connection in a network.
It also provides logical addressing, routing, and then switching.
The network layer is the third layer of the OSI model, this will transfer the data to the transport layer.
Now, let us study each function of the network layer in detail. The first type of function is called host connectivity. The host connectivity is nothing but the one like, when we try to send the data or a type of message, there consists of many numbers of the processes.
Let say that we have a host and a process that is present within the host and the communication between the process to another process is called end-to-end connectivity.
These functions will be taken care of by the network layer of the OSI model. For suppose, if we have a router in between that, then it is called the hop to hop communication which will be taken care of by the data link layer.
The next type of function is called logical addressing, the logical addressing is nothing but the one having a unique address that is not equal to any of the other devices, then it is called logical addressing.
And now, let us now discuss the main concepts of the network layer that are called the switching, and the other one is called routing.
For suppose, if we have a network that is get connected to the other networks where all these networks are connected to the routers or switches. For suppose, if we have the many types of networks that get connected to all of these.
Here, when a packet is sent by the sender through a link and if we want to send the packet to the other link, this type of process we call the switching. here we are just going to switch the packet from one device to that of the other devices.
Now, let us know what actually the routing is?. The process of routing is nothing but we are just trying to create a routing table. These routing tables will be used to send the data packet to the required destination address.
Here we just create the best path in order to send the routing packet through the best path to its destination address. Here the routing is like a process where we can able to find the best path in order to send the data packets from the source to the destination address.

What Are Two Types Of Ipv6 Unicast Addresses? (Choose two.)
Here, we have two different types of iPv6 unicast addresses. They are link-local and the other one is loopback.Today, let us know each type of IPv6 unique address in detail. Here some of the concepts of IPv6 will be similar to the concept of IPv6. Now, let us discuss them in detail.
Here we have the three types of address like the unicast address, multicast address and the other one is called the anycast.Firstly, let us discuss the unicast in detail. we all know that the unicast address can only be assigned to only a single address or only to a single interface.
The unicast address is again divided into the three other classes. They are the global unicast. The global unicast is nothing but, it is similarly equivalent to the IP address version that we normally use as the public addresses. Hence, we can say that IP version 6 is like a global unicast that can be the globally routable IP address.
Here we can say that the device is using only one route and by this, we can easily able to identify a global type of unicast because they all try to come from their own prefix.
This represents that the first three bits which is having like 001 all are going to be the same global unicast Ip addresses.
Now, let us know the second type of function in detail. the second type of function is nothing but the unicast address, the unicast address is nothing but the which functions exactly opposite to the one as the global address. This we called the link-local.
This link-local is nothing but the nonrouted IPs. This link-local is mostly used to send the packets to the other side of the devices which are present on the same link only.
Let us take an example to understand this concept in detail. In the link-local, the router would send packets that are similar to that of the computer. These would use packets in order to send the information from the sender to the receiver and the receiver to the sender.
Here only the router will not forward the packets against the link-local address. The link-local address is mainly used for the communications for the devices that are present over the link.
Here when they are assigned to the single type of interface, we can able to identify this very easily, since all of these will be on the same range. When the IP address begins with the fe80, then we can easily get to know that it belongs to the link-local address.
And the third type is called the unique local address, these unique addresses will all come from the same range. When we see the Ip address with FD00, we get to know that it belongs to the unique addresses. The unique address will be the same as the Ip version 4 private addresses. Hence this cannot be routable over its internet. These are mainly used on the private network segments.

Which Expression Accurately Defines The Term Bandwidth?
The data-carrying capacity is simply called the term bandwidth. Today let us discuss the term bandwidth in detail. Normally, the computer will use the binary language of zeroes and ones in order to communicate from one device to the other device. Each of these transmitting zeroes and ones is called the signals. These signals will be transmitted in the form of electric pulses.
Here the high pulse will indicate a one and while the low pulse will indicate a zero. But how this is related to the term bandwidth. The bandwidth is like a frequency range on which the signals will span themselves. The bandwidth can be measured in terms of the hertz. The basic definition of the bandwidth is that the data that will be transmitted per the unit time that is measured in terms of bits per second. It can also be measured in terms of megabits. The main thing that should be noted by bandwidth is that it can able to increase the speed of the connections, it can also increase the bandwidth connection infinitely.
The term bandwidth is inversely related to the range and it is directly proportional to the speed. Therefore, if we have a connection of wifi network at our home, we will have a higher speed of the connection, but the range of connection will be very low.
The electromagnetic band in the bandwidth will be used in two different ways. They are baseband or broadband. Now, let us know about these terms in detail. The baseband is used in the ethernet connections that will use the whole band in order to transmit one signal of information. And the other one is a broadband connection, it is mainly used in the te; vision, this will able to transmit the number of the signals through the whole band.
The main differentiating property between the broadband and the baseband is that it allows to either send or receive as the signal, but it doesn’t give both at the same time. And the broadband allows to send and receive the signals both at the same time. This usage mainly depends on the conditions for the transmission of the data. It also uses low-frequency waves that can able to deteriorate over long distances.
Hence these are mainly used for short-distance communications which are over a local area network or through the internet. And broadband uses very high frequencies to transmit the information signals in the form of waves which can travel over long distances, Therefore, it can be easily concluded that it is mainly used for long-distance communications. Long-distance communication devices are nothing but televisions or radios.
All this can travel through megabits per second. The bandwidth is nothing but how fast we can send the data from the two devices. For suppose if we had a tank that can fill the water, the maximum capacity of the tank to fill the water is called the bandwidth. It may have different speeds for sending and receiving the data.

What Statement Describes A Characteristic Of Mac Addresses?
Today, let us learn about the definition of the mac address and its characteristics in detail. Simply, in order to transfer the data from one computer to another computer which are not connected to each other, this is called the media access control or called the mac address helps to transfer the data from one device to another device.
The mac address is nothing but a unique identifier that is assigned to the network interface to maintain the communication on the physical network segments. The mac address can be used for numerous technologies like ethernet. In ethernet, the logical mac address is mainly used in the media access control protocol which is the sub-layer of the OSI model.
We have an IP address and the mac address that is typically tied to a key connection device on the computer which is called the network interface card. The network interface card is essentially a computer circuit that makes it possible for the computer to connect to the network.
The network interface card will be able to convert the electrical signals which can be transmitted over the network mac address. The formation of the network mac address is according to the rules of the namespaces, this is managed by the IEEE.
Every network interface card consists of a hardware address called the mac address for a media access control in which all the IP addresses are associated with the TCP and the mac addresses. These TCP and the mac addresses are linked with the network adapters.
Here the mac address is given to the network adapter that is hardcoded into the network interface card. The mac address is a unique one to the network address resolution protocol. This will translates an IP address into the form of a mac address.
We can consider address resolution protocol as a passport that can able to take the data from an IP address into the actual peace of the computer hardware. We have different types of mac addresses. They are a Universally administered address, locally administrated address.
Now let us discuss each of these addresses in detail. The first one is a universally administrated address, it is a uniquely assigned device by the manufacturer, the first three octets will be in the transmission order, which can able to identify the organization that is issued the identifier. These are uniquely known as organizationally unique identifiers.
The mac address and the IP addresses are the globally unique ID, the mac address is mainly used for the local communications on a simple small network. The mac address is mainly used in the network interface cards, the loss of this hardware leads to the loss of all the existing connections in them. The main difference between the mac address and the IP address is that the mac address is mainly used to tell who you are and the IP address is mainly used to tell where you are. The mac address can also be called the physical address.

What Is The Lowest Layer Of The Osi Model At Which Lans And Wans Support The Same Protocols?
The network layer is the lowest layer of the OSI model at which LANs and WANs support the same protocol. Today, let us discuss the network layer of the OSI model in detail. The network layer is layer 3 of the OSI model. Layer 3 is mostly responsible for the routing of the packets from one device to another device across the network.
The main services that are provided at the network layer are fragmentation and reassembly, logical addressing, encapsulation, routing, logical addressing, and handling of the errors.
Now, let us discuss each service in detail. The first is logical addressing, in logical addressing each device must consist of a logical address to communicate every device. The logical addressing can be performed by IPv4 and IPv6.
Now, we assign the logical address to each device so that they can able to communicate with the other device, the assigning of the addresses can be done statically or it can be done dynamically.
The network layer of the OSI model uses the IP address and layer 2 that means the data link layer uses the mac address. The mac address can also be considered as the hardware address. The assigning of the addresses can be done via DHCP servers.
The IPv4 is the most used protocol in recent times, it is a 32-bit address that can be available for over 19 million users but still, it is not sufficient due to an increase in traffic. The stricture of IPv4 address consists of numerals that are separated by the dots.
Due to scarcity in the IPv4 address, the IPv6 has come into the field. The IPv6 is a 128-bit address that consists of both numerals and alphabets. The stricture of the IPv6 address is alphanumeric that is separated by the colons.
Another type of service is routing and encapsulation. Now, let us discuss each of them in detail. The appending from layer 4 to layer 3 by the router is called routing. And the sending of the data to layer 2 is called encapsulation.
The header of layer 3 consists of the IP address so that they can know where the data is going to and from where the data is coming from. The routing finds the best path from the source to the destination address to send the data through the best path.
The network layer also provides the fragmentation and the reassembly, now let us know each of them in detail. After performing the encapsulation when the data is passing through the data link layer, the message or data can be too long in some cases. So the message is divided into different fragments. After dividing the message into multiple fragments, these multiple fragments are then reassembled at the arrival of the destination network layer. The maximum payload size for ethernet is 1500 bytes. The layer three devices will split into the form of the fragments after it reaches to the destination address, the fragments get reassembled.

What Option, When Passed To The Shutdown Command, Will Restart The Local Computer?
The /r option is passed to the shutdown command and will restart the local computer. Today, let us learn how to restart the computer after we click on the shutdown button. Let us do it for the windows 10 operating system.
Here when you click the power button and then shutting down the computer, when you use the option /r it stops shutting down and immediately restarts the computers. We have many shutdown commands and restart commands, now let us learn each of them in detail. We can use different commands to shut down the computer after any specified time.
For this, we do not require any software or application to be installed. we just need to use the commands, here we should click the windows key and writing the command, and press enter. Type shutdown -s -t and write the time when you want to shut down the computer. The time in the command should be entered in seconds. If we want to change the time to shut down the computer, we first need ti to stop the previous timer that we set.
For that, we type shutdown -a in the command prompt. We also have some of the basic commands to shut down and restart the computer using the command prompt. when we want to log out from the computer firstly press the windows +R key on the desktop. Now, you can see the run option, here type cmd over there and click of entering button.
Now it opens the command prompt, types shutdown /l in the command prompt, it will directly logouts the computer. And in order to shut down the Windows computer, you need to use the command called shutdown /s. Repeat the same process as previously and open the command prompt and type the command shutdown /s. And if we want to shut down the computer immediately we just need to enter shutdown /s /t 00.
And if we want to restart the computer by using the command prompt. simply type shutdown /r. As earlier, we need to repeat the same process by clicking the Windows + R command and open the command prompt and type the shutdown /r. And if we want to shut down immediately just type shutdown /s /t /00.
We can also restart the computer by simply using the keyboard. Here press windows + X + U and R, now the computer get restarts. And for shutting down the computer by using the keyboard, we press Windows + X and U 2 times. After this, it directly shuts down the computer. We can also restart the computer by simply using the power shell. By opening the PowerShell as an administrator on a simpler local machine, we type restart-computer and will directly restart the local computer. We can also give restart-computer -Computer name and type the name. And if it receives any error, we can also type restart-computer-Force. Now it will directly restart the computer.

Which Information Does The Show Startup-Config Command Display?
The show startup-config command will display all the contents of the saved configuration file in the NVRAM. Today, let us learn about the startup-config command in detail. We can copy the configuration from the RAM to the NVRAM. This can be done by using the copy config startup-config, this can replace the configuration that is stored in NVRAM. The NVRAM stands for nonvolatile random access memory. We can also able to copy the configuration of a TFTP server.
It allows copying the configuration of both running and the startup configuration. When we try to copy the information from the ram to the NVRAM, it will override the configuration by taking a copy from the NVRAM or by a startup to RAM.
If we want to differentiate between the show startup configuration and the running configuration, we can type show config on the command prompt, this will show the startup configuration. when we type config T we can able to change the IP address to not giving any IP address.
Now, let us learn in detail about the basic commands. The first one shows the startup-config command. Now, to know whether the show startup configuration is present or not, we need to type show startup-config on the command prompt. After pressing the enter, if the startup-config is not present it displays as startup-config is not present. The reason to display the above content is that we didn’t copy the running configuration to the startup configuration.
The second type of the command is called running configuration, when you type the show running configuration on the command prompt we can able to see the running-config on the command prompt. Now, let us learn how to copy from the running configuration to the startup configuration.
Now type copy running-config startup-config on the command prompt and then press enter. Then it will ask the destination file name, now type Y. If it shows any error, use another command called write memory on the command prompt.
After pressing enter, it displays as building configuration (OK). After this in order to recheck, we can use the command show startup-config, nowhere we can see the startup-config. And if we want to erase the startup configuration, we can use the command called erase the startup-config and it displays has as we are sure to remove. Then Type Y on the command and press enter. Now, it will completely remove all the configuration files.
And to check it is erased or not, simply use show startup-config and press enter, now if the startup command has successfully been removed then it displays as startup-config is not present.
We have another command called as history command, which will show all the operations that are performed previously. And we have show terminal, this will show the most recent ten items that we are used.
We can also increase the size of the history and terminal by using the command called as show terminal history size is and write the size number that you want to increase. In this way, we can increase the size of the history and terminal.

What Is One Advantage That The Ipv6 Simplified Header Offers Over Ipv4?
The one advantage that the Ipv6 simplified header offers over Ipv4 is that it can provide privacy and authentication features. Today, let us learn the advantages of IPv6 over IPv4. The IPv6 can able to provide four times more billion addresses than the IPv4 routing, this is taken as the biggest benefit of the IPv6 over the IPv4.
We have more number of the address in the IPv6 when we compare it with the IPv4. All the blocks of the IPv4 are get allocated with the addresses of the IPv4. In IPv6, we do not use any address resolution protocol. The privacy and the authentication features are present in the IPv6, which is not existing in IPv4.
The versions of the internet protocol are IPv4 and IPv6. The IP address consists of two parts. They are the network address and the host address. The size of the IPv4 is 32 bits which are separated by periods. The range of the IPv4 is from 0 to 255. The IPv4 consists of four sets which are of eight binary bits. These sets can be called octets.128 64 32 16 8 4 2 1. Each bit on this octet can be 0 or it can be 1. If we place 1 at that octet then we will count that octet, if we place 0, then we do not count that octet.
The IPv6 is of 128 hexadecimal addresses. The hexadecimal is nothing but, it has both the alphabets and the numbers in it. It consists of 8 sets. Each set has 16 bits in it. It is separated by the colons. We consider IPv6 as the next generation of the IPv4.
Each hexadecimal character will represent 4 bits, so we need to convert 4 bits at a time to convert into the hexadecimal character.
The messages in the IPv6 are sent through the IPv6 packets and all the internet control message protocol version messages are sent through the IPv6 packets.
We have two header lengths in the IPv4, which is got eliminated in the IPv6 since in IPv6 we are dealing with the fixed-length header of 40 bits.
The IPv6 has 28 bits for real-time support, whereas IPv4 has only 32 bits in it.
The IPv6 supports fast processing at the routers when we compare it with the IPv4. It can also support real-time applications other than the IPV4. Presently the internet has provided a speed in Gigabits per second, so it is necessary for the new version protocol such as IPV6 to provide the fast processing.
And as the internet has evolved rapidly, there is also a need to see upon in terms of security. Hence, IPv6 also provides some security support. And with the increase in the wireless network, mobility support is also required. The major advantage of IPv6 is that we have backward compatible support from the IPv4. We can send the information to multiple hosts or users at the same time since the ipv6 supports multicast support.

What Is A Result Of Connecting Two Or More Switches Together?
The number of broadcast domains gets increased when we connect two or more switches together. Today, let us know how to connect two switches. We usually connect many numbers of switches which are of small-medium to large size. All these should connect to each other.
By connecting multiple switches on the computer network is considered as the common functionality. We will have a larger amount of connectivity by connecting the two or more switches together along with its benefits.
Let us list the advantages of connecting multiple switches in detail. The common advantage is, it increases the size of the broadcast domain, we will have more nodes that are connected together. We can also create a larger physical distance on the network.
We have basically two ways in order to make these connections. We have uplink ports where we can connect the uplink port from one switch to the normal networking port.
On the other hand, we have a straight-through cable and port to port by using the normal networking switch ports on the front of the switch by using the cross-over cable.
The first type of connection is the uplink port connection that is between the two switches, when we use an uplink port, the manufacturer will clearly mark that port on a physical switch, we have to use the straight-through type network cable to connect the other switch. And the other switches to the normal network connection ports. These would be the same ports that we might connect to any other device. The below figure represents the straight-through cable. The other switch i.e 2X in the figure is used to connect any devices like laptops, printers, and many more. We have several different reasons for using the uplink port, one switch will be connected to a networking port.
We get more benefits in the way the ports can be configured in the switch configuration. We use one uplink port that is connected to the one regular port and the uplink port that is connected to the next switch’s regular port. we place a button when dealing with the uplink ports in most cases, this button will allow changing the port from an uplink port to the regular port. When we press this button it changes the pin layout inside of the port, in order to make the port uplink or a regular port. This leads to another type of connection between the two switches using the regular network port to the regular network port by using the cross-over cable.
It is the most common type of connection that we use on the network., if we want to connect two switches together by using the regular network ports usually on the front of a physical switch, we have to use the cross-over cable between the two, we cannot use the straight-through cable. Because in straight-through cable, both the switches will attempt to send their data on the second pair of the wires, they try to listen to the data only on the first pair of the wires.
