What is Computer?


A computer is an electronic device that manipulates information or data. It has the ability to store, retrieve, and process data. Nowadays, a computer can be used to type documents, send email, play games, and browse the Web. It can also be used to edit or create spreadsheets, presentations, and even videos.



Functions of Computer:
 A Computer can perform the following set of functions:
 1. Accept data 
 2. Store data 
 3. Process data as desired
 4. Retrieve the stored data as and when required
 5. Print the result in desired format.



Components of Computer:

It mainly has two major components:
 i. Hardware
        1. Input Device
        2. Output Device
        3. Storage Device 
 ii. Software 
        1. System Software
        2. Application Software
        3. Utilities Software

Advantages of Computer:

    1. Multitasking
    2. Speed
    3. Less Cost / Stores large amount of data
    4. Accuracy 5. Data Security

Disadvantages of Computer:

      1. Virus and Hacking Attacks
      2. Online Cyber Crimes 
      3. Decrease in employment opportunity

                      First Generation Computer   First Generation: 1946-1959 is the period of first-generation computer.  J.P. Eckert and J.W.  Mauchy invented the first successful electronic computer called ENIAC, ENIAC stands for “Electronic Numeric Integrated and Calculator”.  Few Examples are:   ENIAC   EDVAC  UNIVAC   IBM-701   IBM-650 Advantages:  1. It made use of vacuum tubes which are the only electronic component available during those days.  2. These computers could calculate in milliseconds. Disadvantages: 1. These were very big in size, weight was about 30 tones.  2. These computers were based on vacuum tubes. 3. These computers were very costly.  4. It could store only a small amount of information due to the presence of magnetic drums. 5. As the invention of first-generation computers involves vacuum tubes, so another ...

Z-WAVE

-
  Z-Wave is a wireless communication protocol that is used for home automation and other low-power, low-data-rate applications. It is based on the ITU-T G.9959 standard and uses the 908.42 MHz frequency band. Z-Wave devices can be used to create a mesh network, in which each device can act as a relay for other devices, allowing for a larger coverage area. Z-Wave devices are typically used in home automation, industrial automation, healthcare, and other applications that require low-power, low-cost, and low-data-rate wireless communication. Z-Wave devices can be powered by batteries and have a longer battery life compared to other wireless technologies. Z-Wave networks can be secured using AES-128 encryption. Z-Wave Alliance is a group of companies that develop and promote Z-Wave technology. Z-Wave devices can be connected to other networks using Z-Wave-to-IP gateways, which allow for remote control and monitoring of Z-Wave devices over the Internet. Z-Wave devices can be integrated...
