Which of the following two operating systems are used most frequently on tablets?
In this article, we see which operating systems are used in tablets. We see a detailed discussion of the operating system and its functions. Let’s start this topic. Do you know what is an operating system? Let me tell you. It is software that is responsible for maintaining the hardware and software of computers and give different computer program services. It also includes processor time accounting software, printing, and many other resources. For the efficient use of computer systems, time-sharing operating systems are also included.
The operating system for the hardware functions includes input, output, and collection of memory act as interlink between the hardware and the program system. The operating system is present in all kinds of devices like computers, mobile phones, tablets, video games, etc. the most importantly implementation code is generating from only by the hardware, and system calls are frequently made to the operating system.
Types of operating systems:
There are different types of operating systems. Let’s see one by one.
Single and multi-tasking:
In single-tasking system can only perform one function. Whereas a multitasking system allows you to perform more than one function. It can only be done by time-sharing when the multiples program times are divided between different processes. These are the features of single-tasking these processes are broken up in different time intervals by a subpart of the operating system. In multitasking, the system is attributed to cooperative types of systems. The one of multitasking is preemptive in this CPU time are divided by operating system and devoted a slit to every program. Cooperative multitasking is obtained by depending on each time of the process and provide time to the other process in a systematic manner.
Single user and multi-user:
In a single user, there is no specialty to differentiate different users instead it allows multiple processes to run in a duet way. While the multi-user operating system, it can differentiate users and recognize different processes and resources. The multi-tasking system function includes a space disk, that is related to users and in multi-tasking, it allows the users at the same time interlink with the system.
Distributed:
In this distributed operating system it maintained different groups and computer networks combined to one computer. It is divided between the computer constituents.
Templated:
In the operating system of the distributed template is relayed to one virtual machine image as the operating system. It acts as a tool for many countless running machines. Both in virtualization and computing management this technique is used.
Embedded operating system:
For embedded computer systems embedded operating systems are developed. It is designed to run small machines along with less autonomy. The main features are compact, highly efficient computing systems. It can operate even in fewer resources.
Real-time operating system:
It can run a process at a specific time of events. A real-time operating system is either single-tasking or multi-tasking. If it is multi-tasking it uses algorithms in this way exact behavior is obtained. For example, switches between different tasks are depended on the preferences or events.
Conclusions:
The frequent operating system used in tablets is android it is quite famous on tablets the main reason for its popularity is free. Even many smartphones are used the new version of android. Alon with android iOS is also used for tablets.

Refer to the exhibit. What is wrong with the displayed termination?
In this article, we discuss the problems related to the displayed termination. In displayed termination, it is important to know that when the cable RJ-45 connection is terminated make sure the length of untwisted wire is not too long. The wires are surrounded by a plastic sheath not are exposed wires. Colored wires are not visible from the base of the jacket.
What is RJ-45 cable?
it is commonly used in ethernet networks for connection. It appears the same as a telephone wire. It is wider than a telephone jacket. It is used in ethernet network so act as the connector on each side so it is called RJ45 cables.
In RJ45 cables RJ stands for registered jacket. In these cables it is a systemize networking link. 45 stands for how many link standards are present there in these RJ-45 cables. It has eight different pins. It means that eight different wires are connected to these RJ-45 cables. When we look carefully at the ethernet networking cables we see the different colors of wires. Out of these eight four are definite colors and the other four are mixture or striped.
How RJ-45 cables are terminated?
RJ-45 cables are removed in such away from the connector pins are facing opposite to you and the clip of the plug is facing toward the bottom then carefully connected these flat wires to the connector. Keep pushing until the ends of the wire come out from pins.
what is ethernet networking?
It is a networking technology in which it accesses different computers and many other devices to communicate with each other in the same network. It is not wireless communication. In ethernet working signals pass through the wires. It is traditional technology in which different devices are connected in a (LAN) local area network and (WAN) wide area network for communication to each other. It is a physical method to transfer data. It received and transmit information with the help of cables. Different types of network cables are used like copper to optical fiber and also from fiber-optic to copper.
Ethernet cable working?
Ethernet network cables are used to provide internet connection. Ethernet cables have different pots where different devices are connected to them. it is used for a Wi-Fi connection or telephone line. Also used in hardware devices like tv, PC, and many other devices require internet.

Address Resolution Protocol
In the OSI model, the ARP (address resolution protocol) is the essential component. The logical address and the MAC address are used for the communication between the computers and the ARO work is to translate or encrypt the logical address to a physical address (MAC).it determines the hardware address of the device.
It has operations and a question arises for its operations in the elective paper: What are two potential network problems that can result from ARP operation? In this topic, we have mentioned the ARP and it’s working along with its operations. The answers to the question are also given in this article. That’s why stay connected to the end!
ARP and Its working
ARP is one of the essential protocols during the data transmission, it helps in the determination of the MAC Address for the IP address at hand. ARP converts the 32-bit IP address to the physical address 48-bits. During the device connected with the local network, ARP is used.
Working:
Suppose the device wants a communication then what does the ARP does? The devices then unfold the header at the Protocol data unit or frames of the data link layer and move them to the network layer. The ARP comes at this point of the transmission.
At this point, the ID of the packets goes or verification with the IP address ID of the destination packet and in case of the match the response to the MAC address of the destination was given or the packet went to the gateway and transfer packet to the connected device in the network and verifies their ID of network. The process remains to continue until the second last reach to the destination where the verification happens and ARP will respond to the destination physical address.
There are the four terms that are used in the ARP and they are given below:
ARP Cache:
The ARP transfer the physical address to its source for future use in case a sudden response is demanded and it is in the ARP table.
ARP Cache timeout:
It is the maximum time of the solved ARP store in the MAC table.
ARP request:
It is used to determine whether the packet reaches the destination physical address or not and it happens by broadcasting it on the network and validate it. Things to know for the validation are given below:
ARP reply:
When the packet reaches the destination MAC address then the response is given to determine it and then the process of the communication began.
What are two potential network problems that can result from ARP operation? (Choose two.)
Answer: the option B AND C are the correct ones the ARP request on a broad level cause the temporary delay in the communication and the hacker also manipulate the physical and logical address by interfering the network traffic. The overflow occurs in the ARO table, not in the MAC table.

What is auto-MDIX?
MDIX stands for the media independent interface with the crossover which is the port on the network switch, router, etc. They are connected with the help of the fiber optic, twisted pair cable, and the RJ-45 connector.it is used in the transmission of the data and it is like an ethernet interface. The correct cable selection is essential because the transmission is essential for the connection.
This topic is about auto-MDIX? And its features? The impact of the auto-MDIX on the selection of the cable? So, stay cling to the end of the discussion to obtain the correct knowledge about auto-MDIX.
Auto MDIX and characteristics
As the medium independent interface determine the physical and electrical interface on the network the auto-MDIX if the connection for the transmission needs the crossover and automatically selects the MDIX correctly to the other end of the link.
the MDI transmits the signal to the router and the transmitted signal from the switch is received in a figure or pattern of crossover the workstation .in a simple way the input and output signals are reversed and it will cause the removal of the twisted pair cable on MDIX port.
Then it has established the connection with simple Ethernet cable and the MDIX with a crossover cable (twisted pair) to differentiate between the MDI or auto-MDIX the word auto which means it can automatically detect the port which also determined if the crossover or simple wire is needed or not. The speed and the few management are also done by the auto feature of MDIX. if the connection is established in the wrong form the feature makes it reset because without this it causes the fails of the transmission.
For the connection of the same type such as MDIX to MDIX, the crossover twisted cable is used so that the signal will match due to the crossover, that’s why the auto-MDIX is established because it can select the needed cable of its use. And for the correct working of the auto-MDIX, the speed of the data needs to be auto. With the auto-MDIX, the resolution time is <500ms.
Nowadays the Dove promoted auto-MDIX has been established within the 1000BASE-T standard which brings the auto establishment of the link in case the auto-negotiation does not occur. With the help of the auto-MDIX, there is no need to e worried whether they use the straight cable or cross over because it can determine automatically the type of the cable and it is the main purpose of its development.
A question has been arising related to the auto-MDIX in the elective exams which is:
What is auto-MDIX?
Answer: The Auto-MDIX is a character which implements on the Cisco switch which helps for the detection and allows the usage of any type of cable connects to the port. so option 4 is the correct answer.

Administrative distance
The administrative root is the values or numbers which are given to the dynamic, static ad directly -connected route. The purpose of the value is for the router ranking from the maximum to the minimum. When the pathway is various in number the router uses the administrator value of the router to determine which path is the best fit for the quick transmission. The low administrative distance value is good.
The router is developed in a way so they have their auto-assigned AD value of every kind of route. The Cisco router which is equipped by OSPF has an auto low AD value than the protocol of the routing information. The OSPF value is 110 while the RIP has 120. the value can also be changed according to choose manually.
Configuration of the administrative distance
When you have two or more source of the information than it becomes very difficult to choose i.e. OSPF wants you to select left and EIGRP want the right at this point the administrative distance will help you to solve the issue. Both of the routes are not suitable at the same time for the network.
The ad helps in a way that each route has the specific value assigned by the AD and it becomes easy for the user to determine the best path. Some of the AD values of the source are in the following:
Source
The lowest is the best and in this table, the EUDRP has the AD value of 90 while the others have greater than this so it is the best. few tips need to know about Administrative distance
During the redistribution, the change in the value of AD is necessary.
FAQs
Q: How to determine the Administrative route?
Ans: To identify the Administrative distance of the router of all the routes Type the IP route command in the command prompt.
Q: What does the 0 mean in the AD?
Ans: the number of the administrative distance is from 0 to 255 and 0 means the lowest AD value and it is the best route while 255 means the highest value and is not trusted by any router.
Q: is the administrative distance value is fixed?
Ans: the administrative distance is local and it can be modified manually to any number but it should be different and unique at the same time.
Q: What is the purpose to use the RIP?
Ans: RIP stands for the “routing information protocol “it is used for the information exchange on a network and it delays or prevents the routing loop and identifies the best route or path.
What route would have the lowest administrative distance?
Answer: the route which is important and the lowest administrative value is then directly connected route to the router. So the correct answer is option C.

Which general-purpose tool can measure characteristics of electricity in a variety of devices?
The tool which is used to measure the characteristics of electricity in a variety of devices is Multi-meter. The multi-meter is a Kind of instrument which measures electrical properties, the basic properties of the electricity which can be measured are voltage, current, and resistance.
We have discussed what are the basic electrical properties of electricity? and the device which can measure these properties in this particular topic. Let’s take a look at the detail of these points below.
Properties of the electricity
The basic properties of electricity are two: the first one is the current and the other voltage. there is another one which is resistance but it is not so important like them.
Voltage is responsible for the following of a current in a wire or a socket. The unit in which it is measure is Volt. voltage is like a pressure that causes the current to move with the speed. For example, the voltage is like the water pipe and the water is the current the pipe causes the pressure and the water flows from it with the speed.
Current is the flow or movement of the charges, which are positive and negative electrons through the socket. The unit of measurement for current is the ampere (A). let’s take the same example the current is the water as long as the more positive and negative charges flow the current rate is higher and vice versa.
Voltage and current are directly proportional to each other. The greater the current the greater the voltage and vice versa. The only thing that can cause a change in them is the resistance in the circuit.
Resistance is another attribute and it is the natural procedure, resistance is defined as those which can oppose the electron flow. For example, the pipe is supposed to supply the water within a specific area of the garden the specific area is the resistance when the area reduces the water flow is also reduced and the resistance between them increase because the pipe is supposed to give water only the garden area whether it is large or short. The unit of the resistance is Ohm.
Multimeter
The multimeter is used to measure the attributes of the electricity. as the multimeter is supposed to measure the current, voltage, and resistance it is collectively called the volt-ohm-milliammeter (VOM) it is the combination of voltmeter, ohmmeter, and ammeter.
Different type of the multimeter is present in the market some of them can deter the smaller fluctuation in the circuit as well. The micrometer is the best one among them because it can display the reading on the screen. The digital multimeter is more accurate and cheaper as compared to the analogous ones. In the field of technology, the multimeter has more scope because the technician can use it to determine which device is getting greater current and which are not, so they can easily balance the supply of the current between them. The latest data energy supply can also detect with the help of the multimeter.

What is defined as a record of a call for help with a computer problem?
A ticket is defined as the recording of a request for help regarding a computer problem. A ticket is a tool for the management of the processing of customer requests. While the records are the collection of the field of the various data types which are fixed in the known place.
In this discussion we are describing what is the tickets system? what are the records or fields? These two are related to the question asked so a thorough knowledge about them is necessary to understand.
What is the tickets system?
The system is formed for the management of the request from the customers, they are also known as the problem which is necessary to solve and store related to the information of the user. The system has to be user-friendly so that the customers can easily understand and use them for problem-solving.
The system is used in various fields, in the IT field is used for the connection with the service desk. The desk is kind of the library which is the infrastructure of IT. There is various cloud-based help desk software in the market. The ticket system is used for the issue-resolving, which is relevant to the events, agents, etc. A ticket is like a request which is only formed when there is a situation that needs to be resolved.
How does the ticket system work?
A document needs to be created at first in the ticket system which is known as a ticket for the interaction recording and it is shared between the customers and rep. It connects the conversation between them in a thread. And if someone needs to know the detail then both have the ticket so they can easily access it and clear the confusion.
After the document the reps solve the problem, it is on their side, and then inform the customer again with the help of the ticket. And the customer again connects with the reps if they have any kind of issue or question to ask. After the problem is solved the ticket is closed and it can open again in case of further issues.
What is a record?
A constant field has a specific purpose such as the record which is the collection of the different datatype with a fixed sequence. The record fields are sometimes known as members and in the OOP, it is known as the element.
The record has the datatype which is known as the record datatype for describing the variables. The latest languages in the computer require the allocation of the latest record type. Every field and identifier datatype needs to know for access.
The record is store in a storage medium such as the main memory, hard disk, etc. These are quite essential for data structures especially linked data types. Most of the files in a computer are placed in the form of records for efficiency purposes.

What does the IP address 192.168.1.15/29 represent?
The IP address 192.168.1.15/29 represents the broadcast address .it is the last address of the given network.it is not allocated to a host but used to communicate with all the hosts of the particular network.
The address 192.168.1.15/29 determines the that network in which we are in has the 29 bits first which is the network address while the rest of the bits which are 3 are the host address. There are a few IP addresses that are specific and they are discussed in the following this abroad cast IP address is one of them:
The number /29 indicates there is 8IPs address together from 192.168.1.8 to 192.168.1.15) and the 6IP are for the host among them (192.168.1.9 to 192.168.1.14). The /29 also indicates that only the last 3 bits can vary remain Address is constant. IP 192.168 is the private address users can use easily but when they are communicating with another network, they can’t be able to use it. Though the 192.168.1.15/29 indicate broadcast, that’s why it is necessary to understand what is the broadcast address? and how does it work?
Broadcast address
A broadcast is the IP protocol that is used in the transfer of packets within the network. The network administrator is used to determine the packet transmission with the help of the broadcast addresses.
DHCP (dynamic host configuration protocol) and various other protocols use the broadcast address IP to locate and transfer the server request. When the IP addresses were built then some of the IPs ae for a specific purpose. The broadcast addresses are for the facility of broadcasting all around the network.
The broadcast address in the IP target not only the single host but all the specific subnet network. The broadcast address is calculated by picking the bit complement of the subnet mask, or it can also be determined with the help of the reverse mask by applying the bitwise OR. The example of the broadcast calculation is given below:
Example:
If the IP address is 192.168.12.220 and the subnet mask is 255.255.255.128 then the broadcast address can be deduced in the following manner.
IP Address: 11000000.10101000.00001100.11011100
Reverse Mask: 00000000.00000000.00000000.01111111
Bitwise OR ———————————————————-
Broadcast Address: 11000000.10101000.00001100. 11111111
How to identify the broadcast address?
To determine the broadcast, address the following steps are required:
The broadcast address is determined with this command, while on the public internet the routers work with the IP addresses or with the tools such as ipconfig. me.

The router is the device that is used in the transmission of packets within a network. It can connect more than two different networks. The router sends a packet from the source to the destination in a way that it will read the address of the packet before sending it toward the destination.
In the scenario the routing table is helpful, when the packet arrives at the router it takes the help of the routing table to determine on which port the packet needs to be sent. The routing table for each router is different and unique which is in the Ram of the device.
Now that you know the brief knowledge of the router and its link to the routing table let’s move to the further discussion of the topic routing table. Because with the help of it you can easily get the answer to the question which is: What routing table entry has a next-hop address associated with a destination network?
What is a routing table?
A routing table as the name indicate is in the form of the table, which is responsible for the packet transmission direct to its destination address within the IP network. The IP-related devices such as the switches and router use the Routing table.
The routing table has the information of all the packets which are forwarded to their destination. Because the packet which is moving first came to the router then the routing table collect the information from them of their source and destination address and then sent the particular packet to its relevant address.
Working on the Routing table
The routing table is working with the ARP cache which stores these addresses. and the dynamic and the static protocol are used to determine the devices.it acts as the resource for determining the next hop, or as we say the route for the packets.
A brief description of the working of the routing table is in the following:
Routing table Terminologies
Few terminologies of the routing table are listed below:
Next hop: It is the destination IP address where the packet is forwarded.
Destination: The final port IP address of the network.
Interface: the network interface which is used when the packet is moving toward the next hop.
Metric: The metric allocates the cost to the routes for the selection of the best-suited path for the packets.
Routes: It has directly or indirectly connected subnets which are accessed through more than one hop.
What routing table entry has a next-hop address associated with a destination network?
The routing table entry of the remote routes has the next-hop address which is related to the destination network. The next Hop is the address to which the IP addresses are moving and it is used for the way toward the destination in a network. The local routes do not need the next hope address.
