Term of the Day " Processor "


 

Definition - What does Processor mean?

A processor is an integrated electronic circuit that performs the calculations that run a computer. A processor performs arithmetical, logical, input/output (I/O) and other basic instructions that are passed from an operating system (OS). Most other processes are dependent on the operations of a processor.

The terms processor, central processing unit (CPU) and microprocessor are commonly linked as synonyms. Most people use the word “processor” interchangeably with the term “CPU” nowadays, it is technically not correct since the CPU is just one of the processors inside a personal computer (PC).

The Graphics Processing Unit (GPU) is another processor, and even some hard drives are technically capable of performing some processing.

Techopedia explains Processor

Processors are found in many modern electronic devices, including PCs, smartphones, tablets, and other handheld devices. Their purpose is to receive input in the form of program instructions and execute trillions of calculations to provide the output that the user will interface with.

A processor includes an arithmetical logic and control unit (CU), which measures capability in terms of the following:

Ability to process instructions at a given time.

Maximum number of bits/instructions.

Relative clock speed.

Every time that an operation is performed on a computer, such as when a file is changed or an application is open, the processor must interpret the operating system or software’s instructions. Depending on its capabilities, the processing operations can be quicker or slower, and have a big impact on what is called the “processing speed” of the CPU.

Each processor is constituted of one or more individual processing units called “cores”. Each core processes instructions from a single computing task at a certain speed, defined as “clock speed” and measured in gigahertz (GHz). Since increasing clock speed beyond a certain point became technically too difficult, modern computers now have several processor cores (dual-core, quad-core, etc.). They work together to process instructions and complete multiple tasks at the same time.

Modern desktop and laptop computers now have a separate processor to handle graphic rendering and send output to the display monitor device. Since this processor, the GPU, is specifically designed for this task, computers can handle all applications that are especially graphic-intensive such as video games more efficiently.

A processor is made of four basic elements: the arithmetic logic unit (ALU), the floating point unit (FPU), registers, and the cache memories. The ALU and FPU carry basic and advanced arithmetic and logic operations on numbers, and then results are sent to the registers, which also store instructions. Caches are small and fast memories that store copies of data for frequent use, and act similarly to a random access memory (RAM).

The CPU carries out his operations through the three main steps of the instruction cycle: fetch, decode, and execute.

Fetch: the CPU retrieves instructions, usually from a RAM.

Decode: a decoder converts the instruction into signals to the other components of the computer.


Execute: the now decoded instructions are sent to each component so that the desired operation can be performed.

Microsoft Edge is now more popular than Firefox thanks to Google Chrome


The browser wars may not be truly over yet but it has taken on a slightly different turn. Internet Explorer has been laughed out of the arena, practically leaving Google Chrome and Mozilla Firefox at the top with a large chasm between them. Now Firefox has suddenly found itself dethroned from its already precarious position by the upstart Microsoft Edge. Ironically, that is mostly thanks to Google Chrome, to be more specific its open source Chromium base.
Microsoft gave it its best shot with its own web browser engine, even taking shots at Chrome’s notorious power-efficiency issue. It would partly eat its own words when it threw in the towel and based Edge on the same Chromium code based that Google builds Chrome on. Now it has taken a leap past Firefox as the world’s second most popular desktop web browser.
That’s mostly thanks to the solid foundations it stands on, delivering the same performance and experience that Chrome users are already familiar with. It is even compatible with many Chrome extensions, even though Google, for a time, tried to scare Edge users from its Chrome Web Store. Whatever Chromium can do, Edge can as well and more.
That’s not to say Edge is simply a Microsoft skin on top of Chrome. For its part, Microsoft did make fundamental improvements, especially when it comes to power management, that Google is also looking into folding back into Chromium. There are also Microsoft-specific integrations, of course, designed to keep Windows and even Mac users from having to jump away from Microsoft software.
Edge’s lead isn’t exactly that great, 7.59% over Firefox’s 7.19%. Even all the other browsers’ combined shares can’t stand up to Chrome’s 68.50%. And when you consider that Edge, Opera, and a whole host of other browsers are based on Chromium in the first place, it’s pretty much Google’s world anyway.

TCL’s new 10 Series delivers a $430 5G smartphone, TCL’s first curved AMOLED display


Originally teased at CES back in January, TCL has finally officially unveiled its 10 Series smartphone lineup for 2020. The new TCL 10 5G, TCL 10 Pro and TCL 10L have a lot in common, but the company wanted to deliver enough diversity across the range to appeal to different buyers at different price points.

Capitalizing on the parent company’s display technology prowess, the TCL 10 series delivers real-time SDR to HDR conversion so that regular content can take advantage of the displays added dynamic range.

TCL 10 5G

Positioned at the top of the range is the TCL 10 5G – one of the cheapest 5G smartphones to hit the market. Powered by Qualcomm’s new Snapdragon 765, the phone also features a 6.53-inchFHD+ display, 6GB of RAM, 128GB of storage, and a microSD card slot.

The phone also features a 4500 mAh battery, reverse wireless charging (we’re assuming it will charge wirelessly as well, though it’s not mentioned in the spec sheet), a rear-mounted fingerprint sensor, a 16MP selfie camera and a  quad-camera setup on the back with a 64MP main sensor, 8MP ultrawide camera, 5MP macro camera and 2MP ultra-low-light sensor for capturing shots in near darkness.

The TCL 10 5G will be making its way to mainland Europe, the UK and the US later this year for €399 and £399 with a sub-$500 price point for the US. 

TCL 10 Pro


Right below the TCL 10 5G is the 10 Pro. While this phone may technically be a step lower than its sibling due to its Snapdragon 675 processor, it still has 6GB of RAM, 128GB of storage and a better 6.47-inch AMOLED display FHD+ which is TCL’s first curved AMOLED display on a smartphone which also sports an in-display fingerprint sensor.

The quad-camera array on the back of the phone features a 64MP (standard), 16MP (ultrawide), 5MP (macro), and 2MP (ultra-low-light) setup with a 24MP selfie camera up front. The phone also has a 3.5mm headphone jack, IR sensor and a 4500 mAh battery.

The phone actually carries a price tag of €449EUR/$449USD/£399GBP and will be making it way to Europe, the US and other global markets starting in Q2.

TCL 10L


The final entry to the series is the TCL 10L which has a 6.53-inch FHD+ LCD, Snapdragon 665, 6GB RAM and 64GB of storage, 4000 mAh battery and a rear-mounted fingerprint sensor.
Like the other two phones, the TCL 10L also has a quad-camera setup, but its sensors have been downgraded to 48MP (main), 8MP (ultra-wide), 2MP (macro), 2MP (ultra-low-light) with a 16MP selfie camera.

As you can imagine, the phone will sell for significantly less than the other two devices at €249EUR/$249USD/£199GBP when it hits the market in Q2 of this year.
