BASIC COMPONENTS OF COMPUTER

Computer consist of some basic components that are required to get correct output.these components are describe below-


1.Input-it consist of that devices which gives user values to the machine basically a keyboard or mouse are basic components that are used to give input.

WHAT IS COMPUTER

Computer is basically a machine that helps you in many ways if i tell you the proper definition than computer is a process that takes input and give the useful output that user wants.this is basically a computer i describe the computer in this way.

GENERATIONS OF COMPUTER

There are Five generations of the computer each one differ each other greatly according to there size cost and power.now i will explain each of them below


1.Zeroth Generation(1791-1871)-
The first digital computer was designed by Charles Babbage an English mathematician.It had a mechanical design where wheels,gears etc were used.As this computer was slow and Unreliable this design could not really become very papular.

TYPES OF OPERATING SYSTEM

Below are the types of operating system.


1.Simple Batch System-
Early computers were working machines. The user of the such system did not interact directly with computer system. The user prepared a job, which consisted of the program, the data and the same control information about the nature of job in the form of punch card and submit it to the computer operator to speed up the processing, operator used to prepare batch of similar program and then execute them one by one the output consisted of the result of the program of the output from each job would be sent back to the operator program.

DEFRAGMENT YOUR PC

 DEFRAGMENT YOUR PC

Fragments are the holes produced in the storage devices due to continuous deletion and copying of files and folders. Holes are created as memory slots in which no file can be stored and are a wastage of memory. Too many holes can lead to unnecessary wastage of memory.

Defragmenting the disk is the process in which these memory holes are removed by placing the files that are stored in continuous form one after the other and close to each other. The defragmenting process is slower but not at all heavy. So you should be patient during this process.

Now read below to see how to defragment the disk.

COMPUTER REBOOTS ITSELF

computer reboots itself

Among billions of computer problems, a single problem that is faced by almost thousand or millions of computer users is the problem of computer rebooting itself again and again. It is a common problem that is being faced by usually users of old computers.
There could be many reasons for this problem, such as hardware problem or simply it could be a virus which can cause a computer to shut down.

How to solve this problem:

In case if this problem is occuring due to virus then you can get it fixed by downloading a good antivirus like Avira antivirus, AVG or Avast. Any of them would be good or you can prefer any other antivirus also. It depends on you.

HOW TO FIX A PRINTER

HOW TO FIX A PRINTER


The problem we would be discussing is "WINDOWS CANNOT CONNECT TO THE PRINTER. ACCESS IS DENIED."


One of the unusual errors which happens in Windows Vista while trying to get a printout from a shared printer is the above error that Windows Cannot connect to the printer. Access is denied.


This is the most recurring error in Windows Vista whenever you try to connect to the printer even when you may think that everything is perfectly done and there is no problem. This problem can show up even when you are able to see the printer on the network and everything is allright.




Even every other thing like shared files, internet access et al seems to work properly but still you are not able to access the required printer to print.

USE A USB HUB

USE A USB HUB

We all know that we are already having 4 USB slots on our mother board and in some new PC's we got 2 extra slots for USB at the front panel of the CPU. In normal conditions we don't require extra USB connections or its rare that someone is trying to connect more than four USB devices at the same time. But in such a if you need to connect more than 6 devices on your PC you can use a device called USB HUB. 

A USB HUB is a device that expands a single USB port to many USB port so that more devices can be connected to that USB port.There are many types of USB HUB in the market. The most commonly used are 4 port and 7 port USB HUB devices.A 4 port USB HUB can cost you 30$ and a 7 port USB HUB can cost you around 40 $.
This USB HUB shown below is a 4 port USB HUB.

WHEN TO ADD MORE RAM

WHEN TO ADD MORE RAM

These things depend on the programs installed and the programs that you are going to install in your PC. There are other factors on which memory depends but if you are going to install a program than you must know the requirements of the program and how much memory it needs. If you are installing a program with memory requirement of 1 GB and you are having 512 MB of memory installed on your mother board than you are not fair to the program because you are not feeding it properly. It will not starve due to low memory but will decrease the performance of your PC to fulfill its needs. This will lead to loss of performance.
