USB 3.1(USB-C) :

Called speed 10Gbps.double the speed of USB 3.0.power direction :Bi-directional.compatible with USB 2.0 and USB 3.0.maximum power output :20V and 5A.smilar size of USB 2.0 Micro-B.Apple new Macbook with USB Type-C.

SSD vs HDD :

SSD-Solise State Disk. HDD: Hard Disk Drive.SSD and HDD are data storage devices.SSD: there are no moving parts.Information is stored in called NAND flash memory.HDD is a mechanical device.SSD so much faster,less power draw,no sound and speed:500Mb/s.HDD-more power draw.spinning sound,av.speed:120Mb/s.


HDMI and Displayport:

HDMI: High Definition Multimedia audio and video interface.Displayport also digital audio,video interface.both  can transfer High definition digital audio,video from a device to a screen.


19pins connectors.3 types(sizes).

1.Type A (normal)-use standard PC,Monitors

2.Type C (mini)-use video and photo cameras

3.Type D (micro) –use tablets and smartphones


4K video resolution is high-definition (HD) video that has four times the resolution of 1080p FHD video. There are two standard resolutions for 4K video. Native 4K with 4096x2160p and 4K UHD with 3840x2160p.

Machine Learning:

Machine learning has taken some massive strides forward in the past few years, even emerging to assist and enhance Google’s core search engine algorithm. But again, we’ve only seen it in a limited range of applications. It won’t be long before machine learning becomes a kind of “new normal,” with people expecting this type of artificial intelligence as a component of every form of technology.




Graphical User Interface- the graphical interface of a computer that allows users to click and drag objects with a mouse instead of entering text .Windows and the Mac OS systems - GUI-based interface. 


Hierarchical File System. HFS is the file system used for organizing files on a Mac hard disk. HFS is a Mac format, Windows PC’s cannot recognize HFS. Windows hard drives -NTFS file systems.


Virtualization allows a single PC to run multiple OS. Virtualization software allows multiple operating systems to run at the same time and even interact with each other.




Intel’s Core M , the first processor in thr world to include ultra­small 14-nanometer transistordcuts power consumption by 60 % and size by half. This paves the way for thinner, fanless tablets and laptops, like the Lenovo ThinkPad Helix.


Bluetooth 5.0:

Laptops and 2-in-1s will be equipped with the latest Bluetooth 5 wireless specification, which is a longer and faster upgrade to the aging Bluetooth 4.2. Bluetooth 5 will allow PCs to communicate wirelessly with devices up to 400 meters away in clear line of sight, but a more reasonable range is about 120 meters, according to analysts.  Bluetooth 5 will transfer data at speeds of up to 2Mbps, which is two times faster than its predecessor.

3D printing:
