Introduction to Computers

What is Computer:
A computer is a Electrical & device mechanical  Device.  
A computer is a programmable machine. The two principal characteristics of a computer are: It responds to a specific set of instructions in a well-defined manner and it can execute a prerecorded list of instructions (a program).

What is Computer Technology:

 computer technology is the activity of designing and constructing and programming computers. Computer technology directly correlates with information technology. Computer technology encompasses a developing list of different software programs and devices. Computer technology is also a very popular degree program offered by many colleges; this degree program tends to focus on learning current operating systems, hardware/software training and computer repair.

The top 05 PC technologies

Bluetooth 5 will take charge

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.

even though a few critics love to knock desktops as dinosaurs, laptops and computers have gotten sexier, faster and even smarter. For every blue display screen of dying, there are droves of technological upgrades riding desktops into the era of digital fact, 4K video and 5G connectivity. right here are the top 10 computer era and developments to observe next year.

VR PCs on your head
VR devices will come in many new shapes and sizes, with some of them acting essentially as PCs that fit on your head. Dell, Asus, Acer, Lenovo and HP will release mixed reality headsets, which will allow users to interact with 3D objects that pop up as floating images superimposed on a real-life background. The devices will provide a new level of human-computer interaction, making it more fun than ever to create 3D objects, play games, watch moves, and have interactive Skype calls. These “holographic computers,” as they have been called, will have Intel chips, an integrated GPU and possibly a 3D RealSense camera to identify objects, measure distances, and provide new perspectives on surroundings.

Storage prices will go up

Prices of SSDs are going up due to shortages, and that could have an impact on the price of laptops, 2-in-1 computers and storage. Dell’s XPS 13 with Intel’s Kaby Lake chips and a 512GB SSD, for example, is not available right now.  Other laptops with 512GB SSDs are priced unbelievably high. Most PC makers are offering 128GB or 256GB SSDs in PCs by default. Choose storage wisely, as it isn’t easy to screw open a superthin 2-in-1 to replace an SSD.

Talk to your PC

The feud between Apple’s Siri, Amazon’s Alexa, Google’s Assistant and Microsoft’s Cortana voice-activated assistants could get more interesting next year. Users will be able to shout out Cortana commands to Windows 10 PCs from a longer distance, thanks to a “far-field speech recognition” technology that Intel and Microsoft are working on. Until now, Cortana worked best if a user was close to a PC, but millions of Windows PCs will turn into Amazon Echo competitors with this new feature. Cortana can do a lot more than Amazon Echo, like accessing information from the cloud, chatting with chatbots, checking email and other tasks.

Beautiful screens, 4K and HDR

Laptops like the XPS 13 and Lenovo’s Yoga 910 have beautiful edge-to-edge screens, a feature that may be included in more laptops next year. Also, 4K screens and HDR (high-dynamic range) technology will make games and movies look stunning. HDR results in more vivid images, and TVs, cameras and monitors supporting the technology are already available. Netflix is also doubling down on HDR. An HDR standards battle is brewing with DolbyVision and HBR3, but GPU makers are supporting both standards. AMD expects DolbyVision to ultimately win.
