Email
E-mail is a method for exchanging digital messages electronically between an author and recipients. It allows transmission of text, files, photos, audio and video. Major email providers include Gmail, Hotmail, Yahoo, and AOL. E-mail works on a store-and-forward model, with the sender's message stored on a mail server and forwarded through internet and satellite links to the recipient's mail server. Key aspects of e-mail include the address format of username@domain, mail servers that act as electronic post offices, and advantages like low cost and speed versus disadvantages like potential for viruses and spam.
How email works
Electronic mail, or email, allows digital messages to be exchanged across computer networks like the Internet. Email systems rely on email servers to accept, forward, deliver, and store messages on behalf of users. An email consists of a header containing sender/recipient addresses and other metadata, and a message body. Standards like SMTP and MIME allow emails to be transmitted and support attachments. Key differences from physical mail include near-instant delivery, lower cost, and less physical effort required.
email clients and webmail (presentation)
Web-based email, also known as webmail, refers to email services accessed through a web browser rather than an email client. Some popular webmail providers include Gmail, Yahoo Mail, and Hotmail. Webmail has advantages like accessibility from any internet-connected computer and not taking up disk space like desktop email clients. However, webmail also has disadvantages like needing an internet connection to access emails and not allowing the use of desktop email clients. Desktop email clients have advantages like always being able to access emails with just an internet connection and being able to use multiple computers without compromising the ability to see all messages. But desktop email clients also have disadvantages such as taking up disk space and not providing built-in virus protection.

Electronic mail
Electronic mail (email) allows transmission of messages over communication networks to a recipient. It contains text, files, images or other attachments. Key features include attachments, address books, support for different file types (MIME), quick delivery, and security. An email address contains a local part and domain name separated by @. A mail user agent (MUA) or email program allows a user to send and receive email by downloading messages to their computer or accessing web-based accounts.
Webmail and Mail Clients
Webmail allows access to email from any computer with an internet browser but requires an internet connection. Mail clients are installed on personal computers, don't require an internet connection but can only be accessed from that computer. Webmail is accessible from anywhere but uses more bandwidth for attachments while mail clients allow customization but take up hard drive space. The best option depends on individual needs - webmail is best for accessibility while mail clients are better for personal computer use.
Web Services
Web services allow for the exchange of data between applications via open protocols and standards on the internet or private networks. Key components of web services include SOAP, UDDI, and WSDL. E-mail and online chat are examples of web services that enable communication. E-mail provides a free and easy way to send messages globally but can also lead to misunderstandings and suck up time. Online chat refers to real-time text messaging between participants and aims for quick responses. In conclusion, web services have the potential to facilitate business transactions but performance may be affected by bandwidth limitations.

All about email
Email is a method for transmitting data, files, photos, and audio/video between computers over the internet. It originated in the 1960s-1970s for communication between computer terminals and evolved with the growth of networks and the internet. Email users can create and send messages with attachments to recipients individually or in groups from commercial programs using an email address format of username@organization.country.
E Mail
E-mail began in 1965 as a way for users of time-sharing computers to communicate. It became popular in 1990 and is now a major form of personal and business communication. E-mail works on a 'store and forward' basis, with messages stored on servers until recipients access their accounts to retrieve messages sent to their username@domain address.
Email Client Server System
This document describes an email system that allows administrators to securely transmit email files and policies from a central server to client computers over a network. The system includes a server that establishes connections between clients to allow them to send, receive, and read messages. Tracking information like the sender, receiver, and IP addresses are included with messages. The proposed system was developed using Java and Swing components on Windows machines to simulate the email sending and receiving process between two users connected through a server.

It provides details on how each method works, such as how email is sent and received through servers, how instant messages are exchanged in real-time between users by screen name, how blogs allow publishing of content in reverse chronological order, how RSS syndicates content summaries, and how BBS originally allowed sharing of text-based messages over dial-up networks.
Report
This document summarizes the key aspects of email (electronic mail). It defines email as a method of exchanging digital messages between an author and one or more recipients over the Internet or other computer networks. Modern email systems use a store-and-forward model where email servers accept, forward, deliver, and store messages. Popular free email services mentioned include Yahoo Mail, Windows Hotmail, and Google Mail (Gmail). Some advantages of email discussed are that it provides a faster, more convenient, and free alternative to traditional mailing; allows for time-sensitive information to be shared quickly; and enables targeted and expanded reach of messages.
Introduction to E-Mail
E-mail functions similarly to regular mail by allowing users to send messages to addresses, but it has key differences - messages are delivered nearly instantly, can be sent to multiple recipients simultaneously, and accessed from any internet connection. An e-mail address contains a username and domain name separated by an "@" symbol, and basic e-mail services are offered for free through web-based providers like Yahoo Mail and Hotmail, as well as through individual Internet Service Providers.

The document discusses basic logic operations and logic gates. It explains that logic operations like AND, OR, and NOT are performed by logic gates and manipulate binary inputs to produce binary outputs. The AND gate produces a HIGH output only if all inputs are HIGH. The OR gate produces a HIGH output if any input is HIGH. The NOT gate inverts the input. More complex logic functions can be built by combining these basic logic gates, including arithmetic operations, comparisons, encoding, decoding, data selection, storage, and counting.
Truth table analysis
The document discusses how truth tables can be used to determine the logical status of propositions and arguments. Truth tables assign truth values (True/False) to propositions based on the truth values of their component statements, allowing the logical status of single propositions and groups of propositions to be determined. The logical status can be tautology, contradiction, contingent, equivalent, satisfiable/consistent, or unsatisfiable/inconsistent depending on the truth values. Validity of arguments can also be determined from truth tables by checking if the conclusion is true in all rows where the premises are true. Examples of truth tables are provided to illustrate these concepts.
Chapter one
The document discusses the different phases of a compiler: analysis, synthesis, and code generation. The analysis phase includes lexical analysis, syntax analysis, and semantic analysis to convert the source code into an intermediate representation.

The document discusses different types of flip flops including JK and T flip flops. It provides information on their structures, truth tables, and time diagrams. It also presents example questions and applications of flip flops in memory, shift registers, and counters.
Logical and Conditional Operator In C language
The document discusses logical operators (&&, ||, !) and conditional operators. It defines each operator, provides truth tables to illustrate how they work, and gives examples of code using each one. The && operator returns true only if both conditions are true. The || operator returns true if either condition is true. The ! operator inverts the value of a condition. The conditional operator ?: is like an if/else statement written in a single line and can be nested to evaluate multiple conditions.
C Structures and Unions
Structures allow grouping of related data and can be used to represent records. A structure defines a template for the format of its members. Structures can contain basic data types and arrays. Structure variables can be initialized, and members accessed using dot operator. Arrays of structures can be used to represent tables of related data. Unions share the same storage location for members, allowing only one member to be active at a time. Both structures and unions can be used as function parameters.
Logic gates
This document discusses digital logic gates and circuits. It describes the basic logic gates - NOT, AND, OR, NAND, NOR, XOR, XNOR - and how each is represented by a truth table. Combinational circuits are defined as having outputs determined solely by current inputs, while sequential circuits can store past input states in memory elements like flip-flops and registers. Examples of common combinational circuits are provided.
Hierarchical Memory System
The document describes the memory hierarchy in computer systems. It consists of several levels of memory organized from smallest and fastest (registers) to largest and slowest (auxiliary memory). Each level above stores data found in the level below but with longer access times. The memory hierarchy aims to obtain the fastest average access speed while minimizing cost by exploiting the principle of locality, where programs tend to reuse the same data or related data over time.
C Structures & Unions
C structures allow grouping of related data items under one name. Structures are scalars that can be passed as function arguments or assigned to variables. Unions share the same memory region for all members, so only one member can be accessed at a time. Both structures and unions allow organizing related data and passing groups of data together.

Truth tables
The document discusses truth tables, which are used to determine if compound statements are true or false. It provides examples of truth tables for negation, conjunction, and disjunction. A conjunction is true only when both statements are true, while a disjunction is true when at least one statement is true. Truth tables can have more than two statements, with each additional statement doubling the number of possible cases.
C pointer
In computer science, a pointer is a programming language object, whose value refers to (or "points to") another value stored elsewhere in the computer memory using its memory address. A pointer references a location in memory, and obtaining the value stored at that location is known as dereferencing the pointer.
Introduction to compilers
A compiler is a computer program that translates a program written in a source language into an equivalent program in a target language. The compilation process involves scanning the source code, parsing it, performing semantic analysis, generating intermediate code, optimizing the code, and finally generating the target code. Key data structures used in compilers include symbol tables to store information about identifiers, literal tables to store constants, and parse trees to represent the syntactic structure of the program.

E-mail was invented in 1971 by Ray Tomlinson and allows computer users to exchange messages over a network. It consists of a header with information like the sender, recipient, date, and subject, and a body containing the message and any attachments. Email works on a client-server model, with clients like Outlook communicating with email servers using protocols like SMTP and POP3 over specific TCP/IP ports. While email enables quick communication, it can also spread viruses and users must be wary of scams. Overall, email remains one of the most effective ways to exchange information electronically.
E -MAIL AND INTERNET
Electronic mail, often abbreviated as email, e.mail or e-mail, is a method of exchanging digital messages. E-mail systems are based on a store-and-forward model in which e-mail computer server systems accept, forward, deliver and store messages on behalf of users, who only need to connect to the e-mail infrastructure, typically an e-mail server, with a network-enabled device (e.g., a personal computer) for the duration of message submission or retrieval. Originally, e-mail was always transmitted directly from one user's device to another's; nowadays this is rarely the case.ThesisScientist.com

Risk Controlling in ISM
Risk refers to situations involving uncertainty of profit or loss. There are four types of risk control: accept risk, mitigate risk, eliminate risk, and transfer risk. Accepting risk means stakeholders approve taking on a risk, like a project failure. Mitigating risk reduces risk to an acceptable level, like assigning experienced managers to a project. Eliminating risk reduces risk to zero by stopping the risky activity. Transferring risk shifts it to another entity, like purchasing insurance to transfer fire damage risk.
Network News Transfer Protocol
The document discusses the Network News Transfer Protocol (NNTP), which uses a reliable stream-based transmission method for distributing, posting, and retrieving news articles. NNTP provides fast transmission through less expensive connections and has characteristics like privacy, security, reliability, and ease of use. NNTP facilitates server-to-server exchanges of latest articles and user-to-server connections where users access accessible newsgroups through news readers. In conclusion, NNTP has proven successful for exchanging ideas but needs improvements to meet growing internet demands and is widely used by newsgroups today.

- 1. PRESENTED BY: DANIYAL KHAN ADEEL AWAN SYED NASIR ALI
- 2. WHAT IS AN E-MAIL?
- 3. Email is a short form of Electronic mail. It is defined as Transmission of messages over communication networks.
- 4. WHAT IS AN E-MAIL SYSTEM?
- 5. It is similar to the traditional mail system with post boxes, post offices, envelopes and addresses. The difference is that here messages are sent electronically to other computer users via Internet.
- 6. One can send computer documents, graphics, software or anything else that can be turned into a digital form attached to an email message.
- 7. Message needs to be converted into a digital form and forwarded to a computer that acts as a mail server or post office.
- 8. Basic Parts of the E-mail System Clients software Message store Message transport Management System Gateways
- 9. Client Software Client software is a user interface that allows users to read and send messages. It shows the list of all of the messages in mailbox by displaying the message headers that shows who sent the mail, the subject of the mail and may also show the time and date of the message and the message size.
- 11. Message Store A Message Store can exist in more than one place at the same time. Its best to keep all email in one main Message Store on the server.
- 12. Message Transport Message Transport Agents (MTAs) are software systems that keep moving messages along to the intended destination.
- 13. Management System Management software is used to create user mailboxes, to maintain address lists and routing information, and to monitor message traffic.
- 14. Gateways Gateways are needed only if a message must be translated in order to travel from a private email system to another, or to the public Internet mail system.
