To search for a file or folder

A file is an item that contains information—for example, text or images or music. When opened, a file can look very much like a text document or a picture that you might find on someone's desk or in a filing cabinet. On your computer, files are represented with icons; this makes it easy to recognize a type of file by looking at its icon.
 A file is an item that contains information—for example, text or images or music. When opened, a file can look very much like a text document or a picture that you might find on someone's desk or in a filing cabinet. On your computer, files are represented with icons; this makes it easy to recognize a type of file by looking at its icon.
 A folder is a container you can use to store files in. If you had thousands of paper files on your desk, it would be nearly impossible to find any particular file when you needed it. That's why people often store paper files in folders inside a filing cabinet. On your computer, folders work the same way. Here are some typical folder icons.
Folders can also store other folders. A folder within a folder is usually called a subfolder. You can create any number of subfolders, and each can hold any number of files and additional subfolders.
Windows provides several ways to find files and folders. There isn't one best way to search—you can use different methods for different situations.

To find a program or file by using the search box on the Start menu

You can use the search box on the Start menu to find files, folders, programs, and e‑mail messages stored on your computer.
To find an item using the Start menu:
Click the Start button, and then type a word or part of a word in the search box.
As you type, items that match your text will appear on the Start menu. The search is based on text in the file name, text in the file, tags, and other file properties.

Note

·         When searching from the Start menu, only files that have been indexed will appear in search results. Most files on your computer are indexed automatically. For example, anything you include in a library is automatically indexed. For more information about the index, see Improve Windows searches using the index: frequently asked questions.

To find a file or folder by using the search box in a folder or library

You're often likely to be looking for a file that you know is in a particular folder or library, such as Documents or Pictures. Browsing for the file might mean looking through hundreds of files and subfolders. To save time and effort, use the search box at the top of the open window.

The search box in a folder or library
The search box is located at the top of every library. It filters the current view based on text that you type. The search looks for text in the file name and contents; and in the file properties, such as in tags. In a library, the search includes all folders included in the library as well as subfolders within those folders.

To search for a file or folder by using the search box:
·         Type a word or part of a word in the search box.
·         As you type, the contents of the folder or library are filtered to reflect each successive character you type. When you see the file that you want, stop typing.
For example, suppose your Documents library looks like this:
Now, suppose that you're looking for your invoice files, so you type "invoice" in the search box. As you type, the view is automatically filtered and you see something like this:
                                                                 
TO FIND A FILE BY USING SEARCH FILTERS
If you're searching for a file based on one or more of its properties (such as a tag or the date the file was last modified), you can use search filters to specify the property in your search.
In a library or folder, click in the search box, and then click the appropriate search filter below the search box. (For example, to search the Music library for songs by a particular artist, click the Artists search filter.)
Depending on which search filter you click, choose a value. For example, if you click the Artists search filter, click an artist from the list.
You can repeat these steps to build complex searches on multiple properties. Each time that you click a search filter or value, terms are automatically added to the search box.

 To expand a search beyond a specific library or folder

If you can't find what you're looking for in a specific library or folder, you can expand the search to include different locations.
·         Type a word in the search box.
·         Scroll to the bottom of the list of search results. Under Search again in, do one of the following:
o        Click Libraries to search across every library.
o        Click Computer to search across your entire computer. This is the way to search for files that aren't indexed (such as system or program files). However, be aware that the search will be slower.
o        Click Custom to search specific locations.

o        Click Internet to search online, using your default web browser and your default search provider.

FUNCTIONS OF AN OPERATING SYSTEM


File Management
One of the functions of the operating system is its ability to manage files efficiently. Thus the operating system manages all the files on the computer. A file is similar to documents and letters kept in file cabinet. It keeps tracks of locations were programs and data are stored within the computer’s memory.

Maintaining Security;
Operations that involve network and larger computers demand an ID and password to each operator to assist him or her gain access to the computer system. The operating system keeps a register of all these IDs so that only people with valid IDs and password can access system. The importance of this is to avoid the usage by unauthorized person have access to system.
Managing Tasks: A computer can perform many tasks simultaneously. One of the ways of doing this is by multi-tasking. Multi-tasking is the ability of a computer to run more than one program at the same time. A typical example is seen by operators listening to music while typing on the same computer.

        In case of networks, the multi-user operating system allows more than one user to access the same data at the same time.

COMPONENT OF A COMPUTER SYSTEM HARDWARE AND SOFTWARE


The two component of a computer are hardware and software.
Hardware: The hardware of a computer are those parts of a computer that can be seen physically. They can be touched, handled etc. these parts were discussed earlier and include motherboard, monitor, CPU etc. these parts are sometimes called the peripherals.
Software: These are set of instructions that are supplied to the computer to aid perform it functions. There are two types of software, system software and application software.

SOFTWARE
As mentioned briefly before, Software is set of instructions that are sent to computer to perform functions. The instructions herein are series of assignment tobe executed by the computer in other to perform a task. Software are of two types i.e. system software and application software.
System Software: These are programs that have already been installed into the computer by the manufacturers to assist the operator. The provide an interface between the users, programmers and operators, the hardware system and the application software.
Application Software: These are programs developed to carry out specific functions. They ease the burden of daily operation of the user. The packages available here are for payroll system, word processing, spreadsheet, desktop publishing etc. application software can be classified into integrated software, general purpose software and custom written or tailor-made software.
General purpose software: as the name implies, general purpose software is not for any specific business, but can be used or adopted to suit specific needs. A particular package for instance spreadsheet can be used for calculations and for other operation such as entering student scores at the end of the term.
Integrated Software: is a set of related, specialized programs combined in unified package that allows data to be transferred easily between the programs.  A major advantage of the package is the ease with which data can be transferred from one component to another. For instance while working on a word processing document you can quickly incorporate a graph created in the packages spread sheet component via a simple cut or copy – and paste operation. Integrated software packages are cheaper than purchasing the packages individually and tends to be more powerful and versatile.
Custom written software These are software design to perform the specific needs of a company. It may be written by individual within the company or contracted out a software house.
Expert/Specialist: These are design to initiate the work of a professional in a particular field.

Operating System: The operating system is a set of programs that governs the operation of a computer. The operating system is as suit of programs provided for the users to assist them in their daily running of the system. Without the operating system no work can be done on the computer. Example of operating system incude; Window 95, Window 98, Window XP, Window NT, Windows 2000, Windows Millennium, Window Vista, Window 7, Window 8 etc.

INPUT AND OUTPUT DEVICE

INPUT UNIT: This comprises of keyboard, mouse and scanner
i. The Keyboard
The keyboard is a tool that is used for typing like a typewriter. Of course, it has more functions than the typewriter. Different keys on the keyboard perform varying functions and include;

A Standard Keyboard
1.    Alphanumeric
2.    Control keys
3.    Cursor keys or arrow keys
4.    Numeric keys
5.    Function keys

Alphanumeric Keys
As the name implies, alpha refers to alphabet and numeric refers to number. Alphanumeric contains both alphabet and numbers. Alphabet are A-Z, and numbers 0-9. apart from alphabet and numbers other keys are associated with these type of keys and include; Shit, Enter, Space, Caps lock, Tab Back space keys.
Functions Keys
These are additional keys on the key board for special usd under operating system and application programs. The keys contained here are F1, F2, F3, F4, F5, F6, F7, F8, F9, F10, F11, and F12.
Numeric Keys
Found at the right hand side of the keyboard, the numeric keys are numbered 0-9 and are used when input are in their numeric form.
Control Keys
Control keys do not have a specific place on the keyboard. They are found on the keyboard  and include; Insert, delete, end, Esc, Print Screen, Scroll Lock, Pause, Home, Page Up, Page Down, Control, Alt, and Num Lock.
Cursor Keys
Also known as the arrow keys the cursor keys help moving the cursor up, down, left and right side on the screen during operation.

THE MOUSE
A mouse is a small hand held device used to control the pointer on the screen. It is connected to the system unit. Mouse shows arrow pointer on the monitor screen for selecting required command from menu rather than typing by using keyboard. When you turn over your mouse you will see a small ball. When you move your mouse over a flat surface the ball rotates. A sensor picks up the movement of the ball, and translates this into movement of the pointed arrow on the screen. You can click, double click, drag and drop and right click on the mouse.

THE SCANNER
Scanner is a machine that you can use it in your computer works. It uses laser beans and reflected light to translate drawing, photos and even text into digital form. These images can then be processed by a computer, displayed on monitor, stored on a storage device or communicated to another computer.


(C)OUTPUT UNIT
An output unit is a medium through which all processed or computed results are made out for the user. This result could either be soft copy output or hardcopy output. A soft copy output is the result displayed on the monitor. It is referred to as the information displayed on a screen or in audio or voice form through speakers. It is said to be a temporal output Hardcopy output is said to be permanent. It refers to output printed on paper. We shall now take a look at the output devices.

SOFTCOPY OUTPUT DEVICES
Monitor
Monitor also called display screen or visual display unit (VDU), are the main means of softcopy unit. Screens are large range from 14 to 21 inches. The screen is coated with phosphor on the back. An electron gun shoots electrons at the back of the screen, creating a glow where they hit. The stream of electrons can be controlled to produced whatever images needed. There are two types of display screens. These are Cathode Ray tubes (CRTs) and Flat-panel displays.

Cathode Ray Tubes
A careful watch at the television screen  gives you an idea of this display screen. The images are represented on the screen by individual dots called pixels. A pixel is the smallest unit on the screen that can be turned on and off or coloured in different shades. The number of pixels determines the resolution on the screen. Resolution here refers to clarity or sharpness of an image when displayed on the screen. Computer aided design (CAD)packages require screen with high resolution so that design can be viewed and worked on in great detail.
Flat Panel Display Screen
These are mainly used on portable computers like laptops. They consist of two pplates of glass with a substance in between them that creates the image on the screen. The different types of flat screen are liquid crystals display (LCD), electroluminescent display (EL) and gas plasma display (GPD).

HARDCOPY OUTPUT DEVICES
Printer: These are output devices used to obtain report after processing. It puts things from the computer into papers varying printers do exist but the common ones are LaserJet, Inkjet and Dox-matrix.
LaserJet Printer: The operation of Laser is similar to photocopying machine. It incorporates the use of laser beam, a mirror and a rotating drum to print characters on papers. The output here is of high quality but slow in speed.
Inkjet Printer: The quality and speed of an inkjet printer are both slow. Printing is achieved by spraying jets that are able to dry.
Dot-Matrix: It prints by creating characters in form of tiny dots. It achieves this by impact. The printer head contains some tiny pins that hit the ribbon to form characters on the paper. It is slow and noisy
