What is Cloud Computing

The rationale behind cloud computing comes from utilities like electricity and water. An article in the 1960’s talked about computing as a utility which can be tapped from the grid like water or electricity.
For starters the concept of cloud computing can be described as the ability to tap IT utilities like machines database or storage from a central grid of computing. You don’t have to bother about buying and storing the inventory of the entire IT infrastructure just inform your cloud service provider what you want and “hey Presto “you get it. You pay for what you use and this saves a lot of cash. Migrating to cloud has become very easy nowadays due to the large number of user friendly cloud services which are provided at reasonably low cost like Amazon, Google, Microsoft and few other niche players.
Cloud commuting services are “on-demand” services provided with the help of internet and can be divided into a set of “utilities as a service”.
  • Software as a services- (SaaS):- This provides useful standalone application access without the need of any maintenance or any additional software or hardware. Many businesses use SaaS model to interact with customers.
  • Infrastructure as a service –( IaaS):- This is a fulfillment model in which storage, servers, hardware and networking elements are outsourced to cloud service providers by clients. Clients pay only for the exact use of the service.
  • Platform as a service- (PaaS):- Allows clients to develop, manage and run applications on platforms provided by the service provider by the service provider without bothering about maintenance of infrastructure.
  • Database as a service – (DaaS):- Provides database access and storage to clients whenever it is asked for.

Today we will discuss about keyboard and its keys types and use. A standard keyboard has 104 keys. Types of Keys in a Keyboard: Alphabet Keys Number Keys Special Keys Function Keys Navigation Keys 1. Alphabet Keys:   26 alphabet keys are present on a keyboard from A to Z. these keys are not present in the alphabetical order. These keys are used to type words, sentences or paragraphs. 2. Number Keys:   These keys are used for typing numbers. These keys are present above the top row of the alphabet keys and also present on the right side of the keyboard. 3. Special Keys:   Keyboard has more special keys such as Space bar Key, caps lock key, backspace key, shift key, enter key, symbol keys and tab key etc. 4. Function Keys:   12 function keys are present on a keyb...

Advantage and Disadvantage of Computer Generations

All computer generations have some advantage and disadvantage today we explain some computer generation advantages and disadvantages. First Generation Computers (1946-1959) The computers produced during the period 1946-1959 with the them technology are regarded as the first generation computer. These computers were manufactured with the vacuum tubes. These tubes were used in the arithmetic and logical operations.  Advantages: They were capable of making arithmetic and logical operations. They used the electronic values in place of the key punch machines or the unit record machines.  Disadvantages: They were too big in size, very slow, low level of accuracy and reliability. They consumed lot of electricity, generated a lot of heat and break down frequently. Second Generation Computers (1959-1965) The computer produced during the period 1959-65 with technology is known as second generation computers. These comp...

What is Vacuum Tube

A vacuum tube is, reasonable enough, a sealed glass tube containing a vacuum in which are present several electronic elements: the cathode, anode, grid, and filament. When the cathode and anode are heated by the filament, and a voltage is applied across them, current flows between the cathode and anode. If a grid is inserted between them, the flow can be controlled by changing the grid between a positive and negative voltage.  The grid voltage can be quite small, and the plate voltages can be quite high, thus providing an amplifying capability. More importantly for computers, switching the grid voltage causes the tube to act as a switch with respect to the plates. Thus, we have an electronically controlled switch that is much faster than a relay. A type of vacuum tube also served as a popular storage mechanism, the Cathode Ray Tube (CRT). Other memory devices used during the period include mercury or glass delay lines, and magnetic core memory. Vacuum tubes, however, are la...
