CONFIGURING EMAIL
INTRODUCTION TO EMAIL
-
Servers, like Microsoft Exchange, store and manage email, contacts, and calendars. They use something called MAPI.
INTERNET EMAIL
-
- Local Email: Managed by a local IT department, like at school or work.
- Internet Email: Hosted online by services like Gmail.
-
- Using the built-in mobile email app.
- Using email websites like Outlook or Gmail.
- Using email apps like Gmail or Yahoo, which are often better than the web.
Email clients are the apps on your device. You need to install them. They're like wizards that make email work. But you still need to know some details to set it up.

iOS Email Configuration
iOS devices have a Mail app for email. It works with many types like iCloud, Yahoo, Gmail, Outlook, and more.
To set up an iOS device, you need an Apple ID. This ID helps you use the App Store, iTunes, and iCloud. It links everything on your device to you.
iCloud email is free and stores your backups, mail, and files.
When you first turn on your iOS device, it helps you set up, connect, and make an Apple ID. You can also bring back your stuff from another iOS device using an iCloud backup.
MOBILITY
Mobility in information technology means using small and lightweight devices that have their own power (like rechargeable batteries) to access information from various places, not just at home or the office. They work as long as there's a cellular or data network available, and you don't need other connected gadgets for them to function.
SMARTPHONE CHARACTERISTIC
Smartphones have their own special operating systems just for them. Sometimes, you can't upgrade these systems, so you might need to buy a new phone to get the latest features and apps. You can usually only install apps from stores like Google Play or Apple App Store. Smartphones use cell networks for calls and data, and they can also connect with other devices through Bluetooth and Wi-Fi.
Non-Field Serviceable Parts
Mobile devices can't be fixed with parts you can buy or replace yourself. If they break, you usually have to send them back to the maker for repairs. If you try to use non-manufacturer parts, it can cancel your warranty and harm your device. But you can change the battery, memory card, and SIM card on your own.
Non-Upgradeable Hardware
Mobile devices usually can't be upgraded with better hardware. Most parts are built into the device's circuit boards. But you can swap out the battery and memory card for bigger ones. And you can add extra functions through built-in ports and docking stations.
Touchscreen
Most mobile devices have touchscreens that let you tap and type. There are two kinds: capacitive (uses a special glass) and resistive (uses layers that touch). They work by detecting changes in electricity when you touch the screen. Some screens can even handle multiple touches at once, like using two fingers.
Solid State Drives (SSDs)
In mobile devices, the parts like circuit boards and memory chips are inside. SSDs (storage) are great because they use very little power, are tough, small, and don't make noise. They're fast because there are no moving parts.
Common Mobile Device Features
Mobile screens can be in portrait (tall) or landscape (wide) orientation. They can automatically turn to match how you're holding the device. You can adjust screen brightness. Mobiles use GPS to do things like find places on maps, play treasure-hunting games, add location to photos, and track lost or stolen devices.
Smartphone Features
Smartphones often have GPS to find your location using satellites. Some apps use this for driving directions. If there's no GPS, phones can still estimate your location roughly using mobile towers or Wi-Fi. Some phones can also share their internet connection with other devices, which is called tethering.
Tablets and E-Readers
Tablets are like big smartphones with the same operating systems. They connect via Wi-Fi and Bluetooth and have USB and audio ports. You can use many phone apps on tablets. Tablets have bigger screens but usually can't connect to cell networks or use GPS.E-readers are like tablets but only for reading. They have touch screens and are great for books. They often use Wi-Fi for book downloads and have longer battery life compared to tablets.
Wearables: Smartwatches and Fitness Trackers
Wearables are gadgets you wear on your body. Smartwatches are like tiny computers you wear, with sensors that track your body and connect to other devices through Bluetooth. Some can even use cellular networks, GPS, and play music. Fitness trackers are simpler and focus on health and activity.
Wearables: Augmented and Virtual Realities
In Augmented Reality (AR), computer graphics mix with what you see in the real world, like adding game characters or useful info.
In Virtual Reality (VR), you wear a special headset to see a whole new 3D world that feels real. Sensors track your movements so you can explore and interact with this virtual world.

Airplane Mode
Airplane Mode is a setting in mobile devices that turns off cell, Wi-Fi, and Bluetooth. It's handy on flights and in places where data costs a lot or is restricted. You can also just turn off cell data if you don't want to use Airplane Mode.
