Personal computer types


Desktop

All-in-one computer

Laptop

Inside a perosnal computer

All PCs have in common is a core set of components:

  • The computer hardware: physical parts of your computer you can see and touch.

  • Computer software: the programs and applications you run on your computer

The Motherboard

Home to Almost Everything

Computer chips and circuit boards are connected to a big circuit called a motherboard

Microprocessor:

The main engine

as seen from above

showing its pins

The specific chip that controls your entire computer system is buried on the motherboard. This chip is called a microprocessor or a central processing unit (CPU).

  • Its speed today is measured in gigahertz (GHz)

Computer memory

Temporary storage

Your instructions to computer are temporarily held in the computer’s random access memory (RAM).

  • The more memory that’s available in a machine, the more instructions and data that can be stored at one time.

  • You can add extra memory

Computer memory

Memory is measure in terms of bytes.

  • one thousand bytes (1,024, to be exact) = a kilobyte (KB)

  • one thousand kilobytes (1,024, to be exact) = a megabyte (MB)

  • one thousand megabytes= a gigabyte (GB)

  • most computers come today with 4GB memory.

Hard Disk Drives

Long-term storage

It permanently stores all your important data. It can store multiple terabytes (TB) of data.

Warning

  • If you try to reformat your hard disk, you will erase all the programs and data that have installed on your computer – SO DO NOT DO IT!

Solid-State Drives (SSD)

Faster Long-Term Storage

  • This type of storage is much faster than traditional hard disk storage

  • SSD is little more expensive than hard disk.

Keyboards:

Computers receive data by reading it from disk, through modem or receiving input directly from you, the user.

  • An input device, the most common input device you use to talk to your computer is the keyboard.

Mice and Touchpads

Point and click input devices

Mouse

Touchpad

Network Connections

Getting connected

  • A network enables you to share files between multiple computers, as well as connect multiple PCs to a single printer or scanner.

  • To share broadband internet connection to that all your computers connect to the internet.

  • You can connect computers via either wired or wireless networks. Connecting a wireless network is as easy as buying a wireless router.

Sound cards and speakers

Making noise

All speaker systems are driven by a sound card or chip that is installed inside your system unit.

Video cards and monitors:

Getting the picture

  • Computer monitors today are built around LCD (Liquid-crystal display) displays, just like you have on your living room TV.

  • Most monitors today come with a widescreen display that has the same 16:9 (or 16:10) aspect ratio used to display widescreen movies.

  • Resolution refers to the size of the images that can be displayed onscreen and is measured in pixels. A pixel is a single dot on your screen; a full picture is composed of thousands of pixels.

    • Most external monitors today can display 1920-1080 or higher resolution (called full high definition, or FHD).

Other parts of your computer

Other devices connect using a special type of cable called a USB (Universal Serial Bus) cable. All computers have multiple USB connections (sometimes called ports).


Printers

To make hard copy of documents and pictures, also includes copying, scanning, and even faxing capability.

Webcams

Small cameras to send live video

Joysticks and game pads

To play the most challenging computer games.

External storage

Just like the hard disk or solid state drives inside your computer, but they connect externally to help you back up your precious data.

Software and Apps

  • Computer software is something you cannot touch because it is nothing more than a bunch of electronic bits and bytes.

  • These bits and bytes combine into computer programs also called applications or just apps.

  • You need a separate software for each task you want to do with your computer.

    • for calculation = spreadsheet or excel
    • for writing a letter = word processing program
    • change pics or videos = photo-editing software
    • to surf internet = need a web browser

Make everything work with OS


  • You interface with your computer via a special piece of software called an operating system.

  • This program makes your system operate; it is your gateway to the hardware part of your system.

Famous Operating Systems


Most computers today come with an OS called Microsoft Windows. It is around 35 years old and is published by Microsoft Corporation.

Laptop

Laptop also called notebook today are the most popular PC.

Files,
Folders, and
Online Storage

Working with Files, Folders, & Online Storage

  • Managing the data stored on your computer is vital.

  • After you save a file, you might need to copy it to another computer, move it to a new location on your hard drive, rename it, or even delete it.

  • You have to know how to perform all these operations—which means learning how to work with files, folders, and disks in Windows.

Understanding Files and Folders

  • All the information on your computer is stored in files.

  • A file is nothing more than a collection of digital data.

  • The contents of a file can be a document (such as a Word memo or an Excel spreadsheet), a digital photo or music track, or the executable code for a software program.

Understanding Files and Folders

  • Every file has a name.

  • Each filename must consist of two parts, separated by a period (.)

    • the name (to the left of the period) and
    • the extension (to the right of the period)
  • A filename can consist of letters, numbers, spaces, and characters and looks something like this: filename.ext

Understanding Files and Folders


  • Windows stores files in folders.

  • A folder is like a parent file; each folder can contain both files and additional folders.

  • The exact location of a file is called its path and contains all the folders leading to the file.

Understanding Files and Folders

For example, a file named ajay_cv.doc that exists in the system folder, which is itself contained in the windows folder on your C: drive, has a path that looks like this: C:\users\yourname\documents\ajay_cv.doc.

Tip

  • By default, Windows hides the extensions when it displays filenames. To display extensions in Windows 11, select View, Show, File Name Extensions.

Using File Explorer

  • In Windows 11, all the items stored on your computer – including programs, documents, and configuring settings – are accessible from File Explorer.

  • You use File Explorer to find, copy, delete, and launch programs and documents.

Launching File Explorer

You can launch File Explorer in one of four ways:

  1. From the taskbar, click or tap the File Explorer icon.

  2. Click or tap the Start button to display the Start menu; then click or tap the File Explorer icon.

  3. Right-click the Start menu to display the Options menu; then click or tap File Explorer.

  4. Press Windows+E on your computer keyboard.

File Explorer Window

Display File Contents & Details

To display the Details or the Preview pane, select View and then select either Details Pane or Preview Pane.

Viewing Files and Folders

To change the file view, click or tap View in the toolbar.

Tip

The Details view is better if you’re looking for files by date or size.

Sorting Files and Folders

  • To do this, click or tap Sort in the toolbar and then select Group By.

  • You can then choose to sort by a variety of criteria, including

    • Name (if you want your file alphabetical),
    • Date Modified,
    • Type (to see all similar files together),
    • Size,
    • Date Created,
    • Folder Path,
    • Authors,
    • Categories, or
    • Title.

Grouping Files and Folders

  • You can also configure File Explorer to group the files in your folder, which can make it easier to identify particular files.

  • For example, if you sort your files by time and date modified, they’re grouped by date (Today, Yesterday, Last Week, and so on).

  • If you sort your files by type, they’re grouped by file extension, and so on.

Searching for Files

  • To use the Instant Search feature, enter one or more keywords into the Search box in the Path bar. Matching files display as you type; you can select one of these or finish entering the keyword(s) and then press Enter.

  • File Explorer displays a list of items that match your search criteria. Double-click or double-tap any icon to open that file.

File and Folder Operations

Use the functions availabe on the File Explorer toolbar.

Creating New Folders

The more files you create, the harder it is to organize and find things on your hard disk.

To create a new folder, follow these steps:

  1. Navigate to the drive or folder where you want to place the new folder.

  2. On the toolbar, select New, Folder.

  3. A new, empty folder appears within the File Explorer window, with the filename New Folder highlighted.

  4. Type a name for your folder (which overwrites the New Folder name), and press Enter.

Naming New Folders

Warning

  • Folder and filenames can include up to 255 characters—including many special characters. Some special characters, however, are “illegal,” meaning that you can’t use them in folder or filenames. Illegal characters include the following: \ / : * ? “ < > |.

  • The one part of the filename you should never change is the extension—the part that comes after the “dot.” That’s because Windows and other software programs recognize different types of program files and documents by their extension. This is why, by default, Windows hides these file extensions—so you can’t change them by mistake.

Renaming Files and Folders

When you create a new file or folder, it helps to give it a name that somehow describes its contents.

To rename a file (or folder), follow these steps:

  1. Click or tap the file or folder you want to rename.

  2. Click or tap the Rename button on the toolbar.

  3. Type a new name for your file or folder (which overwrites the current name), and press Enter.

Copying Files

Copying a file lets you re-create that file in a different location, either on your computer’s hard drive or on some sort of external media. Here’s how to do it:

  1. Select the item you want to copy.

  2. Click or tap the Copy button on the toolbar.

  3. Navigate to the folder where you want to copy the item.

  4. Click or tap the Paste button on the toolbar.

Moving (Cut and Paste) Files

  • Moving a file (or folder) is different from copying it. Moving cuts the item from one location and pastes it into a new location. Copying leaves the item in its original location and creates a copy of the item elsewhere.

  • In other words, when you copy something, you end up with two of it. When you move something, you have only the one instance.

To move a file, follow these steps:

  1. Select the item you want to move.

  2. Click or tap the Cut button on the toolbar.

  3. Navigate to the new location where you want to move the item.

  4. Click or tap the Paste button.

Deleting Files

  • Too many files eat up too much hard disk space—which is a bad thing because you have only so much disk space. Deleting a file is as easy as following these simple steps:
  1. Select the file or files you want to delete. (To select multiple files, hold down the Ctrl key while clicking or tapping.)

  2. Click or tap the Delete button on the toolbar.

This simple operation sends the file to the Windows Recycle Bin

Tip

  • You can also delete a file by selecting it and then pressing the Delete key on your computer keyboard.

Working with the Recycle Bin


Recycle Bin is a special folder on your hard disk that temporarily stores all deleted items.

How to “undelete” or restore a file from the Recycle Bin?

Emptying the Recycle Bin


  1. Double-click or double-tap the Recycle Bin icon on your desktop to open the Recycle Bin folder.

  2. Click or tap the Empty the Recycle Bin button on the toolbar.

  3. When the confirmation dialog box appears, click or tap Yes to completely erase the files; click or tap No to continue storing the files in the Recycle Bin.

Work with Compressed Folders

Compressed folders (sometimes called zip files) take big files and compress their size, which makes them easier to copy or move

Compressing a File


  1. Select the file(s) you want to compress. (Hold down the Ctrl button as you select multiple files.)

  2. On the toolbar, select More (three dots), Compress to ZIP file.

  3. Compressed folder is distinguished by a little zipper on the folder icon.

Extracting Files from a Compressed Folder

The process of decompressing a file is actually an extraction process.

Copy Files to Another Computer


The most popular type of portable drive today is the USB drive (sometimes called a pen drive or flash drive or thumb drive).

How to use USB:

  1. Insert the device into an open USB port on your computer.

  2. After you insert it, the drive appears as a new drive in the This PC section of the File Explorer navigation pane.

  3. Double-click or double-tap the USB drive icon to view the contents of the drive.

  4. Then copy and paste files from your hard drive to the USB drive and vice versa.

When you finish copying files, just remove the USB device (Eject safely).

Copying Files via Email

  • You can send any file as an email attachment; a file is literally attached to an email message.

  • When the message is sent, the recipient can open or save the attached file when reading the message.

Work with Cloud-Based Storage

  • Microsoft offers online storage for all your documents and data, via its OneDrive service. When you store your files on OneDrive, you can access them via any computer or mobile device connected to the Internet.

  • This type of online file storage is called cloud storage because the files are stored on the “cloud” of computers on the internet.

  • It’s all up to you, and all available to any person with a web browser, password permission and an Internet connection.

Access OneDrive from File Explorer

From within File Explorer, click or tap OneDrive in the navigation pane. This displays all your OneDrive files and folders.

Using Microsoft OneDrive

From within any web browser, go to onedrive.live.com and either sign into an existing account or sign up for a new one.

Note

  • Microsoft gives you 5GB of storage in your free OneDrive account

Sync Files on Your PC to OneDrive

To synchronize a file in this fashion, it must be stored in a special OneDrive folder. Then, whenever you connect to the Internet, any changes you make to that file are automatically made to the version of that file stored on OneDrive.

Note

Microsoft OneDrive is just one of many cloud storage services you can use to store and share your files online. Other popular services include Apple iCloud (www.icloud.com), Box (www.box.com), Dropbox (www.dropbox.com), and Google Drive (www.google.com/drive/). All these services work in a similar fashion. Check out the various services before you commit—especially for a paid plan.
