In bi-directional communication, the HTTPs protocol encrypts the communication so that the tampering of the data gets avoided. The advantage of the star topology is that if a link breaks then only that particular link is affected. Answer: Open System Interconnection, the name itself suggests that it is a reference model that defines how applications can communicate with each other over a networking system. Below given snapshot clearly explains the difference: Answer: The time taken for a signal to reach the destination and travel back to the sender with the acknowledgment is termed as Round Trip Time (RTT). There are three types of IP classes and are based on the first octet of IP addresses which are classified as Class A, B or C. If the first octet begins with 0 bit then it is of type Class A.

When packets are transferred using either TCP or UDP, it is sent to an IP address. The __________ allows systems and services to be accessible within an organization. SNMP is widely used in network management for configuring network devices like switches, hubs, routers, printers, servers. If packets are misses then they are just lost, All computers are peers and no computer has control over another computer, Network admin uses one or more computer as a server and provide all accesses, security permission to all other computers in a network, In a Workgroup, each computer maintains their own database. Answer: The main characteristics of networking are mentioned below: Q #32) How many types of modes are used in data transferring through networks? Answer: The size of the network is defined as the geographic area and the number of computers covered in it. But the Internet has made it all so easy. Cloud
Ifconfig (Interface Configuration) is a command that is used on Linux, Mac, and UNIX operating systems. b) Star Topology: In Star Topology, there is a central controller or hub to which every node or device is connected through a cable. Antivirus is a software program that protects a computer from any malicious software, any virus, spyware, adware, etc. Here you can access and discuss Multiple choice questions and answers for various compitative exams and interviews. 1. However, computers that are running on an office network or any workplace network belong to the Domain. Generally, we assign names to websites and computers like Gmail.com, Hotmail, etc. Adding or deleting devices to the network is also easy. HTTPs provides authentication of websites that prevents unwanted attacks. 1. Then the message is transmitted to all the devices of the network. The test contains 40 questions and there is no time limit. b) Data Link Layer (Layer 2): At the Data Link layer, data packets are encoded and decoded into bits and it provides a node to node data transfer. Answer: For data transmission, IP addresses are required and even DNS uses IP addresses to route to the correct website. Meanwhile, there are several other interview questions available on the internet which you can dig out as well. DHCP environment requires DHCP servers to set-up the TCP/IP configuration. 11 Questions | By PA_CHD2011 | Last updated: Mar 17, 2020 | Total Attempts: 8393 .

Routers are similar like little computers dedicated for routing network traffic, In a Network, Hub is a common connection point for devices connected to the network. Dynamic IP is automatically assigned by the server to the network device. Java Multiple Choice Questions And Answers 2021. The below diagram shows how these components are connected with each other in the SNMP architecture: SNMP is a part of the TCP/IP suite. Basic Computer Networking Mcqs Exam questions and answers ebook for Job c) Ring Topology: In Ring Topology, each device of the network is connected to two other devices on either side which in turn forms a loop. Q #7) What is the difference between Hub, Switch, and Router? A. Answer: In data transmission, if the sender sends any data frame to the receiver then the receiver should send the acknowledgment to the sender. In this topology, the devices are not linked to each other. Many web pages are using HTTP to transmit the web content and allow the display and navigation of HyperText. Ethernet is safer than the Internet as Ethernet is a closed-loop and has only limited access. I hope I have covered almost all the important networking interview questions in this article.
