What is Google

GoogleOriginally known as BackRub, Google is a search engine that started development in 1996 by Sergey Brin and Larry Page as a research project at Stanford University. Larry and Sergey decide the name of their search engine needs to change and decide upon Google, which is inspired from the term googol. They later register the google.com domain on September 15, 1997 and incorporated the name on September 4, 1998. What helps Google stand out from its competition and help it grow is its PageRank technique that sorts search results. In the picture below is a capture of the site from The Internet Archive of what Google looked like in 1998.

What Is Remote Access to Computer Networks?

Incomputer networking,remote access technologyallows logging into a system as an authorized user without being physically present at its keyboard.Remote accessis commonly used on corporate computer networks but can also be utilized onhome networks. Remote Desktop The most sophisticated form of remote access enables users on one computer to see and interact with the actual desktop user interface of another computer. Setting up remote desktop support involves configuring software on both the host (local computer controlling the connection) and target (remote computer being accessed). When connected, this software opens a window on the host system containing a view of the target's desktop. Current versions of Microsoft Windows include Remote Desktop Connection software. However, this software package only supports target computers running Professional, Enterprise or Ultimate versions of the O/S, making it unsuitable for use with many home networks. For Mac OS X computers, the Apple R…

Computer Server

Server A server is a computer that provides data to other computers. It may serve data to systems on a local area network (LAN) or a wide area network (WAN) over the Internet.

Many types of servers exist, including web servers, mail servers, and file servers. Each type runs software specific to the purpose of the server. For example, a Web server may run Apache HTTP Server or Microsoft IIS, which both provide access to websites over the Internet. A mail server may run a program like Exim or iMail, which provides SMTP services for sending and receiving email. A file server might use Samba or the operating system's built-in file sharing services to share files over a network.

While server software is specific to the type of server, the hardware is not as important. In fact, a regular desktop computers can be turned into a server by adding the appropriate software. For example, a computer connected to a home network can be designated as a file server, print server, or …

What is OSI(Open System Interconnection) Model

OSI (Open System Interconnection) Definition: The OSI model defines internetworking in terms of a vertical stack of seven layers. Upper layers of the OSI model represent software that implements network services like encryption and connection management. Lower layers of the OSI model implement more primitive, hardware-oriented functions like routing, addressing, and flow control. 
Data communication in the OSI model starts with the top layer of the stack at the sending side, travels down the stack to the sender's lowest (bottom) layer, then traverses the physical network connection to the bottom layer on the receiving side, and up its OSI model stack.The OSI model was introduced in 1984. Designed to be an abstract model and teaching tool, the OSI model remains a useful for learning about today's popular network technologies like Ethernet and protocols like IP.

Examples: Internet Protocol (IP) corresponds to the Network layer of the OSI model, layer three. TCP and UDP corre…

What is Network?

Network1.A collection of computers, servers, mainframes, network devices, peripherals, or other devices connected to one another allowing for data to be shared and used. A great example of a network is the Internet, connecting millions of people all over the world together. Below is an example image of what a home network or small office network may look like. As you can see in the image, this network is setup to enable all computers and other network devices with network abilities, such as the Tivo unit, to communicate with each other, as well as share the single Internet connection.

WhatsApp: Why we love and hate the popular messaging service

Reasons why we love and hate WhatsApp, the popular mobile messaging service... The advent of the instant messaging app on smartphones has completely revolutionised the way we communicate. Here are some ways how it has come about:
The benefits...
1. Wishing on festivals and special days used to cost a bomb with telcos charging standard SMS and call rates on those days. With WhatsApp, we do not have to care for the rates any more
2. Standard smileys were common in SMS language, but WhatsApp emojis have rendered some words unnecessary. An emoji of two beer mugs clunking does a better job than 'Cheers!'
3. Earlier, sharing pictures instantly meant mailing them, putting them up on Facebook or sending through an MMS. Now, you can just click and share in no time.
4. We actually used to ring the doorbell to our friend's house and then we took to calling them. Now we WhatsApp them that we're waiting outside.
5. Earlier you had to try hard to avoid a group of people i…

Difference between 2G and 3G Technology

Second Generation (2G) technology was launched in the year 1991 in Finland. It is based on the technology known as global system for mobile communication or in short we can say GSM. This technology enabled various networks to provide services like text messages, picture messages and MMS. In this technology all text messages are digitally encrypted due to which only the intended receiver receives message. These digital signals consume less battery power, so it helps in saving the battery of mobiles. The technologies used in 2G are either TDMA (Time Division Multiple Access) which divides signal into different time slots or CDMA (Code Division Multiple Access) which allocates a special code to each user so as to communicate over a multiplex physical channel. 3G technology generally refers to the standard of accessibility and speed of mobile devices. It was first used in Japan in the year 2001. The standards of the technology were set by the International Telecommunication Union (ITU). Thi…
