In this post i am sharing Basic Networking Interview Questions for all Project Developers. The Basic Networking Knowledge is required for all software Developers. The following are the few of the Basic networking Interview Questions.
1) What is Network?
Ans: A network is a set of devices connected by physical media links. It is used to share resources such as data, printers,CD-ROM and exchanging files. The main purpose of the networking is to share information.
2) What is Node?
Ans: A network can consists of two or more computers directly connected by some physical medium such as coaxial cable or optical fiber. Such a physical medium is called as Links and computer it connects is called as Nodes.
3) What is Protocol?
Ans: A Protocol is a set of rules that govern all aspects of information communication.
4) Define Routing?
Ans: The process of determining systematically Hoe to forward messages toward the destination nodes based on its address is called routing?
5) What is gateway?
Ans: A node that is connected two or more networks is commonly called gateway. It generally forwards message from one network to another.
6) What is difference between Gateway and Router?
Ans: The Gateway operates at the upper levels of the OSI model and translates information between two completely different network architecture or data formats.
7) What is Bandwidth?
Ans: Every line has an upper limit and a lower limit on the frequency of signals it can carry.This limited range is called the bandwidth.
8) What is MAC address?
Ans: The address for a device as it is identified at the Media Access Control(MAC) layer in the network architecture. MAC address is usually stored in ROM on the network adapter card and is unique.
9) What is SMTP?
Ans: SMTP stands for Simple Mail Transfer Protocol. It is used to exchanges mail between servers.
10) Define Proxy Server?
Ans: A proxy Server speaks the client side of a protocol to another server. This is often required when clients have certain restrictions on which servers they can connect to. When several users are hitting a popular website, a proxy server can get the contents of the web server's popular pages once,saving expensive inter network transfers while providing faster access to those pages to the clients. Also,we can get multiple connections for a single server.
11) What is difference between TCP and UDP?
Ans: These two protocols differ in the way they carry out the action of communicating. A TCP protocol establishes a two way connection between a pair of computers whereas the UDP protocol is one way message sender. The common analogy is that TCP is like making a phone call and carrying on a two-way communication,while UDP is like mailing a letter.
12) What are the seven layers of OSI model?
Ans:
Ans: DHCP stands for Dynamic Host Configuration Protocol,a piece of the TCP/IP protocol suite that handles the automatic assignment of IP address to clients.
14) Is it possible to get the Local host IP?
Ans: YES. By using InetAddress getLocolHost method.
15)What is peet-peer process?
Ans: The process on each machine that communicate at a given layer are called peer-peer process.
16) What is Checksum?
Ans: Checksum is used by the higher layer protocol(TCP/IP) for error detection.
17) What is subnet?
Ans: A generic term for section of a large networks usually separated by a bridge or router.
18) Define Encoder?
Ans: A device or program that uses predefined algorithms to encode,or compress audio or video data for storage or transmission use. It is a process to convert between digital audio and analog video.
19) Define Decoder?
Ans: A device or program that translates encoded data into its original format. The term is often used in reference to MPEG-2 video and sound data,which must be decoded before it is output.
20) What is RAID?
Ans: It is a method for providing fault tolerance by using multiple hard disk drives.
