What is a database?
A database is used as an organized mechanism that is able to
store, manage and retrieve information. They make this possible by the use of
tables. These tables consist of columns and rows. Every column has a different
attribute and every row and every row corresponds to a single record. Although
they are similar to spread sheets databases are in fact a lot more powerful in
the way data is manipulated. There is a wide range of actions that databases
can do that spread sheets cant, for example:
Update records in bulk
Perform complex calculations
Retrieve all records in a certain criteria
Cross-reference records in different tables
All of the above examples give a good insight as to why
databases are much more efficient than paper based solutions. This is because
if you were to update in bulk on paper it could take you hours whereas on a
computer based data base it could be done in seconds, and you can easily see if
you made a mistake and it’s simple to correct it. Similarly if you were to try
to take on complex calculations on paper based, this would not only take you
personally to be good at maths, but could also take a long amount of time,
whereas a database can take minimal effort and time without making mistakes.
Forms
Database forms are often referred to as “data entry
screens”. They are interfaces which are used to work with your data and
normally contain command buttons, which all perform different commands. A way
to create databases without these forms is to edit the data in the table’s
datasheets. Although a lot of database software and users prefer forms for
viewing, entering and editing data. Another bonus of using forms is using
command buttons, you can program certain buttons to choose which data shows up
on the form, open different forms, and do much more, such as, you could have
specific form for a customer, with command buttons, you could have a command
button that would open this customers order form, which you can then edit.
Forms can also be used as a method of security, this is because you can create
forms that will only show certain fields and will only allow certain operations
to be performed. These are more efficient than paper based solutions because
you would need a number of sheets for each customer alone, so you would have
less chance of losing it. It also allows security, which isn’t possible on
paper based solutions.
Reports
Database reports present data from a database, these reports
can be printed from the database which allows you to view the data quickly and
easily. Reports are the summary of your database they can present the
information visually in the form of graphs and charts etc. They are more
efficient than paper base solutions because they automatically summarise the
data, they also can automatically and instantly present the data in forms of
graphs and charts etc. whereas paper based solutions would require you
personally to summarise and present the data, which could take a long time.
Switchboards
A switchboard is a form that contains a navigation
menu which allows you to switch to other queries, reports and forms in your
database. These are more efficient than paper based solutions because on a
paper based solution you would have to navigate your own way around sheets and
sheets of paper whereas on a database with switc

An operating system is a layer of control which
allows the user to interface between the hardware and the software. The
operating system is in charge of managing the computer and it allows the user
to run software.
There are many different operating systems available, but the most popular ones are Windows, Mac OS X and Linux.
Most modern operating systems have a GUI and multitasking features. A GUI is graphic user interface and it is what you see on your monitor, it allows you to easily access installed programs. Multitasking is when you run two or more programs at a given time, early systems did not support this, so when you were running painting software and you wanted to change to text editor you would have to close the painting software in order to run the other piece of software.
Modern computers allow you to run almost limitless software at the same time as a result of large amounts of RAM and powerful multi core CPUS.
The three main types of operating systems are Linux, Windows and Mac OS X.

The three main types of operating systems are Linux, Windows and Mac OS X.
Most operating systems now come with their own
security, for example Windows 8 features Windows Defender, this is a program
that runs in the background and notifies you when you need to take an action,
it also allows you to scan your computer for malware if your computer is
running slow or isn’t working, it also protects you online and prevents you
clicking on virus links or emails containing a virus. They also have internet
security, this will prevent you from downloading files that contain viruses.
Windows features ‘My Documents, My Pictures, My
Music, My Videos and Downloads’ this allows you to manage your files as soon as
you get the computer and want to transfer documents across from an old computer
etc. All files that you download should automatically go into your ‘Download’
folder, but you are able to choose where your files save to. You are also able
to create folders in these main folders to make your files neater and easier
now to navigate. In windows it is also possible to have more than one user
on the computer at the time and you can leave a user running in the background.
Machine and peripheral management manages all the
devices installed on the computer, the sort of things that machine and
peripheral management manages are things such as external storage devices,
phones, cameras etc. This allows transfers of things such as music, pictures
and videos; it also allows you to back up devices such as mobile phones.
