Introduction to SNMP
SNMP is a set of protocols for managing network devices. It uses a manager-agent model where a manager controls and monitors agents, usually routers. SNMP relies on SMI to define object naming and types and MIB to create a collection of named objects and their relationships. Objects are given OIDs starting with 1.3.6.1.2. SNMP versions 1 and 2c provide limited security while version 3 adds authentication and encryption. SNMP uses community strings for authentication in versions 1 and 2c and username/password in version 3. Common packet types include get, set, and trap requests.
Domain name system
The document discusses the Domain Name System (DNS) which maps domain names to IP addresses. It describes how DNS works hierarchically with a root server at the top level, below which are generic, country-specific and other domain levels. DNS servers store and distribute this mapping information across multiple computers to avoid a single point of failure. Primary DNS servers store and update zone files mapping domain names to IP addresses, while secondary servers transfer this information from primary servers.
UDP - User Datagram Protocol
Overview of UDP protocol.
UDP (User Datagram Protocol) is a simple extension of the Internet Protocol services. It basically provides simple packet transport service without any quality of service functions.
Unlike TCP, UDP is connection-less and packet-based. Application PDUs (application packets) sent over a UDP socket are delivered to the receiving host application as is without fragmentation.
UDP is mostly used by applications with simple request-response communication patterns like DNS, DHCP, RADIUS, RIP or RPC.
Since UDP does provide any error recovery such as retransmission of lost packets, the application protocols have to take care of these situations.
Network Layer,Computer Networks
The document discusses the network layer in computer networking. It describes how the network layer is responsible for routing packets from their source to destination. It covers different routing algorithms like distance vector routing and link state routing. It also compares connectionless and connection-oriented services, as well as datagram and virtual circuit subnets. Key aspects of routing algorithms like optimality, stability, and fairness are defined.
E Mail Ppt
Podcasting allows people to listen to recorded radio shows when they want using mp3 players. Chatting and instant messaging programs like Yahoo and AOL enable electronic communication and recreation. Discussion boards bring together people with shared interests to argue and share ideas on topics. Text messaging is used primarily for short personal communication and gossip rather than professional reasons. Blogs are online journals where individuals post multiple entries on a specific topic, with examples including Blogger and TypePad.
Email ppt
E-mail is a method for exchanging digital messages between an author and recipient(s) across the internet or computer networks. It allows for communication, sharing of information and ideas, record keeping, group work, and staying in touch both professionally and socially. Some advantages of email include low cost, ease of referencing messages and attachments, ease of use, speed, and global accessibility. Disadvantages include potential for emotional responses, information overload, lack of personal touch, and misunderstandings.
Tcp and udp
TCP guarantees reliable delivery of data packets in the correct order, while UDP does not provide these guarantees. TCP is commonly used for applications that require reliable data transfer like HTTP and FTP. UDP is used for applications that prioritize speed over reliability, such as media streaming, VoIP, and online games. While TCP ensures error-free transmission, it introduces more overhead and latency than UDP. The choice between TCP and UDP depends on an application's requirements for reliability versus speed.
BASIC CONCEPTS OF COMPUTER NETWORKS
A computer network connects computers and devices together through communication devices and transmission media. It allows sharing of resources like printers, files, data and information. There are three main types of networks - local area networks (LANs) within a small geographical area, metropolitan area networks (MANs) within a city, and wide area networks (WANs) across large areas like countries. Network architecture refers to the overall design of a computer network and describes how it is configured and what strategies are used. The two main architectures are client/server, where a server provides services to clients, and peer-to-peer where all computers have equal capabilities without a central server.

For a K-segment pipeline with a clock cycle tp, the first task takes Ktp to complete while remaining tasks finish every tp, with all N tasks completing in (K+N-1)tp time.
Object oriented programming
The document discusses object oriented programming and its advantages over other programming paradigms. It notes that object oriented programming uses classes and objects to make programs easier to develop collaboratively, more robust, and easier to debug. Key concepts of object oriented programming discussed are polymorphism, encapsulation, inheritance, and abstraction. The document also outlines four programming paradigms - monolithic, procedural, structured, and object oriented programming - and their characteristics.
If and select statement
This document discusses conditional statements in VB.NET. It describes if statements, including if-then, if-then-else, and if-then-elseif statements. It also covers nested if statements. Additionally, it explains select case statements and their different forms for exact matches, relational tests, and range checks.
Depriciation
This document discusses depreciation accounting and two methods for recording depreciation - charging depreciation to the asset account or maintaining a provision for depreciation account. Under the first method, depreciation reduces the asset value each year. Under the second method, depreciation is credited to the provision for depreciation account each year so the asset remains at original cost, with depreciation accumulated in the provision account. Journal entries and an example asset account are provided to illustrate the two methods.
BLOCK DIAGRAM OF HARDWIRED CONTROL UNIT
The document discusses the control unit in computer architecture. It notes there are two kinds of control units: hardwired and microprogrammed. A hardwired control unit is made up of sequential and combinational circuits to generate control signals. It has the advantage of fast operation but the disadvantage that the wiring must be changed if the design needs to be altered. The document includes a block diagram of a hardwired timing and control unit.
Accounting standards(as)
This document discusses Accounting Standard 2 and 6. AS 2 provides guidance on determining inventory costs and valuation. It specifies methods for computing inventory costs and determining the amount to report in financial statements. AS 6 deals with depreciation accounting. It applies to all depreciable assets except certain specified items. AS 6 requires that the depreciable amount of an asset be allocated systematically over its useful life and that the depreciation method be applied consistently over time. Both standards provide principles for uniform accounting practices related to inventory valuation and depreciation.
Listing skill
This document discusses listening skills and effective listening. It defines listening as the process of hearing, understanding, and interpreting spoken words. Listening is the most important communication skill and requires practice and attention. While hearing is simply picking up sound waves, listening is an active process that involves analyzing, organizing, interpreting sounds and messages to understand their meaning. Tips for effective listening include being mentally prepared, evaluating the speech not the speaker, making eye contact, being patient, avoiding arguments, being open-minded, and asking clarifying questions. Effective listening is important for communication and stimulates better speaking.
If and select statement
This document discusses conditional statements in VB.NET, including if statements, if-then-else statements, if-then-elseif statements, nested ifs, and select case statements. It provides the syntax and examples of each type of conditional statement. The if statement executes code depending on a boolean expression being true or false. Select case statements allow checking multiple mutually exclusive conditions and executing different code blocks.
Object oriented programming
This document discusses Object Oriented Programming and different programming paradigms. It provides an overview of OOP concepts like polymorphism, encapsulation, inheritance and abstraction. It also describes four programming paradigms: Monolithic Programming, Procedural Programming, Structured Programming, and Object Oriented Programming. The last paradigm, OOP, focuses more on data and divides programs into classes and objects that can communicate with each other through functions.
Listeningskills 120213044302-phpapp01
Listening is the most important communication skill and requires active attention and participation. Effective listening involves hearing sounds, organizing them into patterns, interpreting meanings, and understanding messages. Problems in communication are often due to ineffective listening. While hearing is a sensory process, listening is an active process that involves comprehending, evaluating, and responding to messages. It is important to focus attention on the speaker, avoid distractions, and ask clarifying questions to ensure understanding.
Euler’s formula
The document discusses Euler's formula in mathematics. It establishes the relationship between the number of vertices, edges, and regions of any connected graph as V - E + R = 2. It then provides results on the maximum number of edges for planar graphs with a certain number of vertices. Finally, it gives an example problem asking to determine the number of regions, degree of each region, and identify the exterior region for a sample graph.
Stack 111104232459-phpapp02
A stack is a Last In, First Out (LIFO) data structure where objects inserted last are removed first. It has operations like PUSH which adds an object to the top of the stack, POP which removes and returns the top object, and PEEK which returns the top object without removing it. The document was created by Rahul Sharma about data structures using C for the subject teacher Mr. Jasvinder Singh.
Smart cards 07521102013
Smart cards are credit card sized plastic cards with embedded integrated circuits and chips that conform to ISO 7816 standards. They are used for applications that require high security and authentication, including credit and debit cards, medical cards, identification cards, entertainment cards, and voting cards. Common uses of smart cards include secure user authentication for computers and networks, encryption of sensitive data, subscription information for satellite TV receivers, pre-paid phone cards, storing patient healthcare histories, and electronic ticketing for public transportation, parking, and road tolls.
Data,information and database
Data refers to raw inputs that become meaningful when processed or organized into information. A database is a collection of organized data that meets users' needs. A database management system is a set of programs that allows users to store, modify, and extract information from a database. Examples of databases include computerized library systems, ATMs, flight reservation systems, and computerized parts inventory systems. Queries are used to request specific information from a database in the form of stylized questions.
Array
This document defines and explains the different types of arrays in C programming, including one-dimensional, two-dimensional, and multi-dimensional arrays. It provides the definitions, declaration syntax, and memory allocation of each array type. One-dimensional arrays are linear collections of elements, two-dimensional arrays arrange elements in a matrix, and multi-dimensional arrays extend the concept further with additional indices.
Basic computer fundamentals
This document provides an overview of basic computer concepts including hardware, software, and the language of computers. It defines a computer as a programmable machine that can execute a set of instructions. It describes important hardware components like the CPU, hard disk, RAM, monitor, and peripherals. It explains that software has no physical form and discusses operating systems and applications. It also covers the digital language of computers using bits and bytes to represent information.
Rolling friction
Rolling friction is the force that opposes the rolling motion between two surfaces in contact. It is less than sliding friction because when a wheel rolls over a surface, the point of contact has zero velocity relative to the surface, so there is no slipping between the surfaces. This means less force is needed to overcome rolling friction compared to sliding friction. Because rolling friction is less, vehicles with wheels can transport heavy loads more efficiently than sliding loads, and motorcycles can travel farther on the same amount of fuel since their tires roll rather than slide.
