Networking technologies underlie all IT activities and a strong comprehension of the hardware and protocols used to create networks is essential to future success. What is a Computer Network?
Ans: A computer network is a connection network between two or more nodes using Physical Media Links viz. In addition, some method of connecting these building blocks is required, usually in the form of galvanic cable most commonly Category 5 cable.
Same content. Network Architecture Network architecture is the overall design of a computer network that describes how a computer network is configured and what strategies are being used. This is a great idea if you're entering into the networking world for the first time or are needing a refresher before a new job or school assignment. However, relatively few quality free books exist that cover general computer networking topics. Follow the links below to download and read the best free computer networking books online.
Some of these free networking books download in a format that requires a special program or app to read it. If you need to convert one of these books to a new document format that works with a specific computer program or mobile app, use a free document file converter.
There are 24 chapters in this book that are separated into three parts: Author Eugene Blanchard completed this book based on his experience with the Linux operating system. As humans remember names, the computer understands only numbers. Generally, we assign names to websites and computers like gmail. When we type such names the DNS translates it into numbers and execute our requests.
Translating the names into numbers or IP address is named as a Forward lookup. Translating the IP address to names is named as a Reverse lookup.
This is used to design or develop standards that are used for networking. Q 50 What is the use of encryption and decryption? Ans Encryption is the process of converting the transmission data into another form that is not read by any other device other than the intended receiver.
Decryption is the process of converting back the encrypted data to its normal form.
An algorithm called cipher is used in this conversion process. Q 51 Brief Ethernet? For example, if we connect a computer and laptop to a printer, then we can call it as an Ethernet network.
Ethernet acts as the carrier for internet within short distance networks like a network in a building. The main difference between Internet and Ethernet is security. Ethernet is safer than the internet as Ethernet is a closed loop and has only limited access. Q 52 Explain Data Encapsulation? Ans Encapsulation means adding one thing on top of the other thing.
When a message or a packet is passed through the communication network OSI layers , every layer adds its header information to the actual packet. This process is termed as Data Encapsulation.
Note: Decapsulation is exactly the opposite of encapsulation. The process of removing the headers added by the OSI layers from the actual packet is termed as Decapsulation. Q 53 How are networks classified based on their connections? Ans Networks are classified into two categories based on their connection types. They are mentioned below, Peer-to-peer networks P2P : When two or more computers are connected together to share resources without the use of a central server is termed as a peer-to-peer network.
Computers in this type of network act as both server and client. Generally used in small companies as they are not expensive. Server-based networks: In this type of network, a central server is located to store the data, applications etc of the clients.
The server computer provides the security and network administration to the network. Q 54 Define Pipelining? Ans In Networking when a task is in progress another task gets started before the previous task is finished. This is termed as Pipelining. Q 55 What is an Encoder? Ans Encoder is a circuit that uses an algorithm to convert any data or compress audio data or video data for transmission purpose.
An encoder converts the analog signal into the digital signal. Q 56 What is a Decoder?
Ans Decoder is a circuit which converts the encoded data to its actual format. It converts the digital signal into analog signal. Q 57 How can you recover the data from a system which is infected with Virus?
Ans In another system not infected with a virus install an OS and antivirus with the latest updates. Then connect the HDD of the infected system as a secondary drive. Now scan the secondary HDD and clean it. Then copy the data into the system. Q 58 Describe the key elements of protocols?
Ans Below three elements are the key elements of protocols Syntax: It is the format of the data. That means in which order the data is displayed. Semantics: Describes the meaning of the bits in each section.
Timing: At what time the data is to be sent and how fast it is to be sent. Q 59 Explain the difference between baseband and broadband transmission? Ans Baseband Transmission: A single signal consumes the whole bandwidth of the cable Broadband Transmission: Multiple signals of multiple frequencies are sent simultaneously.
