computer engineering benefits to society18. Can a variable be both const and volatile? Yes. The const modifier means that this code can’t change the worth of the variable, but that does not imply that the value can not be changed by indicates outside this code. For instance, in the example in FAQ 8, the timer structure was accessed via a volatile const pointer. The function itself did not adjust the value of the timer, so it was declared const. However, the worth was changed by hardware on the computer, so it was declared volatile. If a variable is both const and volatile, the two modifiers can seem in either order.

As you can see, even such a modest technique can handle multiple heavy applications at the same time. Even though computers have a number of cores these days, there are generally numerous a lot more threads than there are cores, so thread switching (multiplexing) is nevertheless needed.

Answer: The name Harvard Architecture comes from the Harvard Mark I relay-based laptop. The most apparent characteristic of the Harvard Architecture is that it has physically separate signals and storage for code and information memory. It is attainable to access plan memory and data memory simultaneously. Normally, code (or system) memory is read-only and information memory is study-write. As a result, it is impossible for system contents to be modified by the program itself.

Sa mga panahong iyon, tuwang-tuwa sila sa tuwing nakakakita ng laptop. Mayroon silang isang computer ngunit napaglumaan na ito, dito pa namin ginawa nung bestfriend ko yung highschool report namin. Ibig sabihin, yung laptop ko ang pinakabagong model. The vonneumann Architecture is named soon after the mathematician and early personal computer scientist John von Neumann. von Neumann machines have shared signals and memory for code and information. Thus, the program can be effortlessly modified by itself since it is stored in read-create memory.

Software program keyboards or on-display keyboards often take the form of laptop applications that show a picture of a keyboard on the display. One other enter device corresponding to a mouse or a touchscreen can be utilized to function every digital key to enter text. Software program keyboards have develop into extremely popular in touchscreen enabled cell phones, as a result of additional cost and area requirements of other kinds of hardware keyboards. Microsoft Windows, Mac OS X, and some types of Linux embody on-display screen keyboards that may be controlled with the mouse. In software program keyboards, the mouse must be maneuvered onto the on-screen letters given by the software program. On the press of a letter, the software writes the respective letter on the respective spot.

The keyboard remained the first, most built-in laptop peripheral well into the era of personal computing until the introduction of the mouse as a client machine in 1984. By this time, text-only consumer interfaces with sparse graphics gave strategy to comparatively graphics-wealthy icons on display However, keyboards remain central to human-computer interaction to the present, even as cellular personal computing units similar to smartphones and tablets adapt the keyboard as an non-obligatory digital, touchscreen-based means of information entry.

In regular usage, the keyboard is used as a text entry interface for typing text and numbers right into a word processor , textual content editor or another program. In a modern pc, the interpretation of key presses is mostly left to the software program. A pc keyboard distinguishes each physical key from every different key and studies all key presses to the controlling software. Keyboards are additionally used for computer gaming — either regular keyboards or keyboards with special gaming options, which can expedite often used keystroke combos. A keyboard can be used to give instructions to the working system of a pc, similar to Home windows ‘ Management-Alt-Delete combination, which brings up the system safety options display screen.

As the letter-keys had been hooked up to levers that wanted to move freely, inventor Christopher Sholes developed the QWERTY format to cut back the chance of jamming. With the arrival of computers, lever jams are now not a difficulty, however nevertheless, QWERTY layouts had been adopted for electronic keyboards as a result of they had been widely used. Various layouts such as the Dvorak Simplified Keyboard will not be in widespread use.

Common environments for multifunctional keyboards are complex, excessive-efficiency workplaces for financial traders and management room operators (emergency services, safety, air site visitors management; business, utilities administration, etc.).…

Connector, BIOS And CMOS – Motherboard Component

The connector has been stuck on the motherboard.

A device that connects motherboards to chassis. In general, the connector is soldered to the motherboard, so external components such as keyboards, printers, speakers, etc. can be connected directly to the motherboard.
. And all connectors connected to the motherboard always follow the standards set. For example, the power supply connector in the cabinet will match the connector on the motherboard. The connector itself is divided into three types:

Connector, BIOS & CMOS - Motherboard Component

a. Power Connector
The power connector is a pin that connects the motherboard to power
supply on the chassis of a computer. On AT type motherboards, the casing needed is AT type too. AT type power connector consists of two parts, where two cables from the power supply will stick there. On the ATX type, the power supply cable integrates in one header intact, so you just plug it in on the motherboard. This cable consists of two columns according to the pins on the motherboard that comprise
above two pin arrays too. There are several motherboards that provide two
type of power connector, AT and ATX. Most of the latest motherboards are already
ATX type.
Power supply is connected to the motherboard through colorful cables and large plastic connectors.

b. Floppy and IDE connectors
This connector connects a motherboard with a permanent storage device such as a floppy disk or hard disk. The IDE connector in a motherboard usually consists of two, one is the primary IDE and the other is the secondary IDE. The Primary IDE connector connects the motherboard to the primary master drive and the secondary master device. Meanwhile, the secondary IDE connector is usually connected with a device for slaves such as CDROM and slave hard drive. how to connect pin with cable? So easy. The IDE cable ribbon has a red stripe on one side. The red strip marks, the side of the red berstrip cable is pinned to the number 1 pin on the connector. When stuck in reverse, installed devices will not be recognized by the computer. The same applies to connecting a floppy cable with a pin on the motherboard.

c. Keyboard Connector
There are two types of connectors that connect the motherboard to the keyboard. One is a serial connector, while the other is a PS / 2 connector. The serial connector or type AT is round, larger than the PS / 2 model, with 5 pin holes. Meanwhile, the PS / 2 connector has a 6 pin pin hole and is half the diameter compared to the AT model.

BIOS and CMOS

BIOS (basic input output system) is a collection of programs found in EPROM (Eraseble Programmable Read-Only Memory) or EEPROM (Electrically Eraseable PROM) which are also recognized as Flash ROM chips. The BIOS functions to initialize and configure peripherals primarily in the input and output processes. BIOS position is between hardware and computer operating systems (Windows, DOS, Linux, OS / 2, etc.). Besides that bios also functions to control the interaction …
