1.Overview of Computer System Unit Parts
The Computer System Unit
The system unit is the box-like case that contains the electronic components of a computer. Many people erroneously refer to this as the CPU. Here you will find devices like the power supply, different drives, the fan, the connectors, and the motherboard. Note that in most cases, the monitor, keyboard, and mouse will not be found inside the system unit layout.
Other names for the system unit include the computer chassis, cabinet, box, tower, enclosure, housing, or simply case.











The Motherboard

The motherboard is sometimes called the system board or main board. It is the main circuit board of a microcomputer. This component contains the connectors for attaching additional boards. All other parts connect in one way or another to the motherboard.
This part typically contains the CPU, BIOS, memory, mass storage interfaces, serial and parallel ports, expansion slots, and all the controllers required to control standard peripheral devices, such as the display screen, keyboard, mouse, and disk drive.
When you are reading about motherboards, you won't fail to come across the term motherboard form factors, which describes the general shape, the type of case, and the power supply it can use. It also describes the physical organization of the motherboard.










Hard Disk Drive
A hard disk drive is a high capacity, non-volatile, magnetic data storage device with a volume (disk) that is usually non-removable.
Data is magnetically read and written on the platter by read/write heads that float on a cushion of air above the platters.

Power Supply Unit

The power supply unit (PSU) is used to convert AC currents from the main supply to the different DC voltages required by various computer components.
Power supplies are quoted as having a certain power output specified in watts, A standard power supply would typically be able to deliver around 350 watts.
You will need more power from the power supply if your PC has more operating components.

A computer mouse is a handheld hardware input device that controls a cursor in a GUI and can move and select text, icons, files, and folders. For desktop computers, the mouse is placed on a flat surface such as a mouse pad or a desk and is placed in front of your computer. The picture to the right is an example of a desktop computer mouse with two buttons and a wheel

A computer keyboard is one of the primary input devices used with a computer that looks similar to those found on electric typewriters, but with some additional keys. Keyboards allow you to input letters, numbers, and other symbols into a computer that can serve as commands or be used to type text.

                                                                        DATABASE TABLE= A   table   is a collection of related data held in a structured format within a   database . It consists of   columns , and   rows . In  relational databases , and  flat file databases , a  table  is a set of data elements (values) using a model of vertical  columns  (identifiable by name) and horizontal  rows , the  cell  being the unit where a row and column intersect. [1]  A table has a specified number of columns, but can have any number of rows. [2]  Each row is identified by one or more values appearing in a particular column subset. A specific choice of columns which uniquely identify rows is called the  primary key . "Tab...

 PROGRAMMING Programming  is the process of taking an algorithm and encoding it into a notation, a programming language, so that it can be executed by a computer. Although many programming languages and many different types of computers exist, the important first step is the need to have the solution. Without an algorithm there can be no program. Algorithms describe the solution to a problem in terms of the data needed to represent the problem instance and the set of steps necessary to produce the intended result. Programming languages must provide a notational way to represent both the process and the data. To this end, languages provide control constructs and data types. Control constructs allow algorithmic steps to be represented in a convenient yet unambiguous way. At a minimum, algorithms require constructs that perform sequential processing, selection for decision-making, and iteration for repetitive control. As long as the language provides these basic state...

                                                   DATABASE MANAGEMENT SYSTEM      A database management system (DBMS) is system software for creating and managing  databases . The DBMS provides users and programmers with a systematic way to create, retrieve, update and manage  data . A DBMS makes it possible for end users to create, read, update and delete  data  in a database. The DBMS essentially serves as an interface between the  database  and end users or  application programs , ensuring that data is consistently organized and remains easily accessible. The DBMS manages three important things: the data, the database  engine  that allows data to be accessed, locked and modified -- and the database  schema , which defines the database’s logical structure. These three ...
