What Are the Benefits of Setting Up an Nfs Server?
Answer:
The benefits of setting up the network file storage server are, that it stores files in the network drive and also allowed them to be shared over the other networks.
Network file storage:
NFS is the protocol used to share files over networks. It is defined as the methods the data stored in the files and recover from the storage devices like tape drives, solid-state drives, and hard disk drives. It is the network file sharing protocol over the networks.
It is invented in the 80s to provide the facility to share remote files between the servers. There are many versions of network file systems among these NFS v3 is common. For the files to be accessible to the remote computer users it allows the administrators to share the whole file or the portion of some file. Clients with verification access to the shared file system. Remote procedure calls are used for the route between the clients and server.
Benefits:
NFS is evolved for better performance and for the best file-sharing system. It is very cheap and easy to use for network file sharing. Here are some benefits of the NFS,
- Organize the file system that is transparent to all the users.
- Allows different clients to use the same files, so everyone on the network uses the same data.
- Computers share apps that reduce the space for the local disk and eliminate the storage cost.
- Data are up to date because all the users use the same files on the same network. The data is up-to-date, consistent, and reliable.
- NFS is a mature and open protocol. It means that most of the features like securing, implementing, and using are easy to understand. It is the open protocol because of its continued development of documents on the internet as an open network protocol.
- The network file system has consolidated management that decreases the requirements for added disk space and software for the individual user system.
- NFS is a user-friendly and distributed file system. This protocol is very easy to handle and allows the users to access remote files the same way as accessing local ones. It is used as a distributed file system, there is no need for removable media devices like CDs and DVDs.

What Is an Example of Network Communication That Uses the Client-Server Model??
Answer:
Option C is correct. An example of network communication that uses the client-server model is the workstation that stimulates the DNS request when the user type www. Cisco.com in the address bar of the web browser. This request is the client-server model.
Client-server model:
It is the distributed application that separates the task or workload between the source called the server and the requester server called the client is known as the client-server model. Both server and client communicate with each other on separate hardware over a computer network, but both are present in the same system. A server is responsible to run programs and the resource is shared with the client but the client does not need to share its resource. The client stimulates communication with the servers waiting for the incoming request. The client-server model uses the computer applications of are world wide web and printing network.
The best application that the client-server model use in network communication is to access the bank. When the client requested to enter his bank details, they made a request to the bank server. Then the bank server verifies the login credentials and then provides the service to the customers.
Network communication:
The five common types of the network communication are,
Benefits of using the client-server model:
There are many benefits of using the client-server model,
- Due to single server hosting all the data are placed in the same place which provides a facility for data protection and management of the user verification.
- Access to the data in an efficient way.
- Resources such as servers, computers, and network segments are added to the network without any interruptions.
- Data transferred on the client-server model is the platform agonistic.

Option CRead more
What Is Indicated by The Term Throughput??
Answer:
Option C is correct. The term throughput indicated that it is the measurement of the bits transferred over the media in a given time period. Throughput is affected by a number of factors such as latency and EMI. In throughput, it measures the data bit also other bits like encapsulation, overhead, and acknowledging. Goodput is the measurement of transferred unstable data across the media.
Throughputs:
Throughputs actually measure how many bits of information are transferred over a network in a given time. It is widely applied to systems including various aspects of the network system and computers in organizations. Measure the productivity of the system includes the specific, response time, how much specific workload is complete, and how much time elapses between the user’s request and the recipients’ response.
In business, throughput is related to the amount of product produced by the company and how much deliver to the customers in a given period of time. The terms mostly used in companies are the rate of production or speed of producing the product. So, the business with the high throughputs takes away the market shares from the low ones because high throughputs mean that the company produces a service or product more efficiently than the competitors.
Benefits:
The total time taken by the service to be produced from start to finish is called throughput time. Throughputs time break into a different time,
Processing time:
It indicates how long the processing time is to produce a service.
Inspection time:
It checks the quality of the product and monitored the finished service.
Moving time:
It indicates how much time is required to transport, ship, and deliver the service to the logistics chain.
Waiting time:
It is the queue time between these components.

What Is the Mac Address of Ffff Ffff Ffff Ffff?
Answer:
Media access control is the physical address that is used to recognize our device in a network. It is the confusing that MAC address is the device. Actually, media access control is of NIC used in the device in this way device has a 2- 3 different media access control based on the number of network interface cards (NIC). Same as ethernet WLAN has a different MAC address.
Media access control is in hexadecimal form. Ffff. Ffff.ffff.ffff is a special MAC address that indicates a broadcast frame. In the CAM table, media access control is not added to it
Media access control:
It is the network data transfer policy that controls how data is transferred between two computer terminals with the help of network cables. The OSI reference model includes the sub-layers of the data link layer 2.
The center of the media access control is to make sure that non-collision and very easy to transfer data between two terminals of the computer. A collision occurred when the data transfer over the network at the same time. It causes the breakdown of communication and cause costly for an organization.
MAC control methods:
To avoid collision between the terminals nodes when data is transferred the three major ways to avoid collision are,
Function:
The main function performed by the media access layer are as follows,
- It provides protection against errors and generates and checks frame check sequences.
- LLC PDUs have a transparent layer,
- Delimiting and recognition of the frame.
- Provide the convenience of source station addressing information.
- It provides access to the physical transmission medium.

Refer To the Graphic. What Type of Cabling Is Shown?
Answer:
The correct option is C. the cable used with respect to the graphic is the fiber. A network cable includes different types of cables such as,
Fiber optical cable:
The fiber optic cable consists of a core, jacket, and buffer. The composition of the core is made from thin strands of plastic or glass that cover the long distance to carry data. outside the core, there is cladding that wrapped the core, and the cladding is wrapped by a buffer then outside the buffer, there is the jacket. The function of these parts is,
Fiber optical cable is mostly used to transfer data over a long distance with high speed. The maximum distance is 40 Kilometers and the speed is 100Gbps. It is completely immune to electromagnetic radiation. Light is used by fiber optics to send data; light is reflected in the fiber from one point to another point. On the basis of the number of beams of lights, there are two types of fibers,
- Single-mode fiber
- Multimode fiber.

What Is the Result of a DHCP Starvation Attack?
Answer:
Option C is correct. As a result of the DHCP starvation attack, the authorized clients are unable to hire an IP address. DHCP is introduced by attackers with the aim of creating DoS for clients. In order to achieve the aims hackers, use tools that send many messages to hire the available internet protocol address and make them refuse the authorized hosts.
Dynamic host configuration protocol:
The DHCP is a layer of application network management protocol that provides the automatic and fast system for the assignments and distribution of internet protocol addresses and also distributes the IP configuration information for clients in the network. It is also used to assign subnet mask information, DNS (domain name system) address, and default gateway address. DHCP is time-bound by the lease time, which means how often needs to reopen.
Dynamic host configuration protocol starvation attack:
In this starvation attack, the hackers send multiple DHCPREQUEST messages to the DHCP server with the take-off MAC source within a short period of time in order to empty the whole server pool of IP addresses and avoid the race competition. The starved DHCP server does not show respond to the new request until the new address is available. The server set the stage for the attackers to pass themselves into the DHCP server and then send spoofed messages to the clients on the network to trick other clients.

What Is the Media Access Control?
In the open system interconnection (OSI) media access control the is the sublevel of the data link layer for data transmission. MAC is responsible for controlling the flow and multiplexing the transmission medium. It also controls the transmission in the form of data packets with the assistance of remotely shared channels. Over the network interface card, it sends the data on it.
The main objective of the MAC protocol is to avoid collisions and the smooth transfer of data in the form of packets between the two terminals of the computer. A collision happens when two or more terminals transfer data at the same time. It will cause a communication breakdown which is costly for the organization.
In the OSI model MAC layer:
The OSI model framework is the layered networking framework that shows how communication takes place between heterogeneous systems. The second-lowest layer is the data link layer which is further divided into two sublayers,
MAC control methods:
The channels through which data is transmitted between two terminals to avoid collision have three major ways to fulfill this task it includes,
The functions of media access control:
- It encapsulates the frames so these frames are used for transmission through the physical medium.
- It provides a distraction to the physical layer of logical link control and the upper layers of the open system interconnection.
- When more than one data is to be transmitted MAC is responsible for the multiple access resolution. Transmission channel access methods are also determined by the MAC layer.
- It solves the addressing of the source stations and the group of stations source.
- It avoids the collision between the two terminals ans also stimulate the re-transmission in case of collisions.
- MAC provides protection against errors in transmission and generates the frame check sequence.

What Is the First Step to Performing Hardware Maintenance?
Answer:
The first step to perform hardware maintenance is to turn off the computer and remove its power source.it is necessary for maintenance to de-energize the system. It means that switch off the PSU (power supply unit) and after that cycle the power button. Unplugged the power supply unit completely from the wall but if you leave it plugged you have a grounded framework for static reasons.
Essentials computer maintenance steps:
With the advancement in technology, computers come in different shapes and sizes that connect us with the digital world at any time and place. Computers must be maintained for work last longer and perform efficiently
Keep your PC in good condition both externally and internally Rapid battery drain and overheating of the processor lead to computer crashes. In order to avoid this need to maintain the commuter hardware.
Defense with padding:
If you are the people who travel with a PC you need to protect against drops, slips, and bumps. Shiels your PC with a protective case. A few different styles of protection are used that offer different levels of functionality. it includes are,
Organize cords:
The thing that is more frustrating to deal with long and confusing cables is mixed up and tangled in the process. Taking your time and organizing the wires from your PC ports is a good first step for both laptop users and desktops. Here are some suggestions for cable routing:
Unplugged the PC:
Optimal battery power is a top priority in wireless devices. There are a few more scary things than the battery draining is when you work for hours and then play left of your schedule. It is needed to resist to plugged in when the PC battery falls under 50%. It will cause overcharging and leads to your laptop battery does not hold a charge for a long time. In order to avoid this situation, remove the plug when the battery is 100% and do not plug in until the battery the low.

What Occurs When a Collision Happens on a Network?
Answer:
Option B is correct. On the network when the collision occurred it will cause the nodes to wait a random amount of time on the network and then resend the transmission.
Collision in computer networks:
The collision occurred when two or more computers try to send signals at the same time. The main function of the networking access method is to handle the collision, for example, a collision occurs in the Ethernet frame when two or more stations attempt to position the frame on the wire at the same time. To control this situation Ethernet uses the access methods such as CSMA/CD so that each node takes turns accessing the wires.
Working of Collision:
When the stations start transmitting the signal and mark the error station stop working and issued a signal to tell other stations that errors are detected due to collisions Both stations stop working and wait for a random period of time before relaying signals. The amount of time the stations need to wait depends on the number of collisions in the network.
In the OSI model, a collision occurred at the physical layer of this model. At the physical layer when multiple devices share a common media, there is a chance for collisions. The collision domain is where a collision occurred in the network.

What Is the Difference Between Whoami and Logname Commands?
The Log name command is the simple user that is part of the GNU core utilities. The main purpose of the Logname is to print the name of the current user. There are no arguments because there are no other options and commands. You just need to call and print the name of the current user. Logname commands do not get mixed or confused with the LOGNAME environmental variables. The LOGNAME variables can be changed by the users. This is the conflict in the Logname command it uses the wtmp/utmp log-in records to withdraw the name of the user.
There is a variety of tools that can be used to print the current login users. Some tools show a lot of switches and options while some are effective only for user identification. Whoami is the tool it is different from the Logname command. Let’s see a quick difference between these two commands.
A lot of information about the users is shown by the Whoami commands. It presents the columns of information and header also. The base output is changed by the different switches and options. This information is good but most of the time you need a simple answer. So, the Whoami command exhibits additional information, it shows all the logged-in users into the system. This additional information and a lot of information make it different from the Logname command.
The Logname command just prints the name of the current users. This is also very easy to use if the bash script is used you just need the current user’s name. The Logname command is different from the Whoami command if you are using the Sudo command. In the normal situation, both are used to print the user’s name but when you are the root user with the assistance of sudo then Whoami indicates you are the root user.
