What is the any key on a computer keyboard?

There is no such key on standard keyboards. Such questions are related to a humorous but likely apocryphal story about novice computer users.

According to the anecdote, a new PC user encounters the instruction "hit ANY key to continue". Seeing other keys such as enter, escape, shift, and control, the user calls technical support to find out which key on the keyboard is the ANY key. While this seems unbelievably naive, similar queries have been made about various computer instructions since the earliest days of personal computers.

What are different types of assemblers?

There are two types of assemblers: pass1 and pass2. The difference of which is the number of times the assembler will parse the code in order to generate machine code. Generally, a 2 pass assembler will take longer to compile, but has the benefit of allowing the programmer to define symbols anywhere in the code. This results in code that is easier to read, manage, and debug.

What is value of enter key then how to get that value in c?

The new line character ('\n') has the ASCII value 10 decimal, 0x0A hexadecimal. In some cases, a new line may be preceded with a carriage-return (ASCII 13 decimal, 0x0D hexadecimal), however the carriage return is only of relevance to line printers.

To determine when the enter key is pressed, capture the character via stdin and test for equality with the '\n' character.

Ict vs it?

Pelgrum and Law (2003) state that near the end of the 1980s, the term 'computers' was replaced by 'IT' (information technology) signifying a shift of focus from computing technology to the capacity to store and retrieve information. This was followed by the introduction of the term 'ICT' (information and communication technology) around 1992, when e-mail started to become available to the general public (Pelgrum, W.J., Law, N., 2003). According to a United Nations report (1999)1 ICTs cover Internet service provision, telecommunications equipment and services, information technology equipment and services, media and broadcasting, libraries and documentation centres, commercial information providers, network-based information services, and other related information and communication activities.

What is statistical modeling?

What is the scope of sociolinguistics?

Chomsky (1965) redefined the nature of its object. He recognized 'competence' in language as the fluent native speaker's knowledge of grammar and as a subject of human capacity. The term 'competence' is largely unexamined; a different set of competences comprising of distinctive abilities other than grammar. Also, Chomsky assumes that competence is something underlying behavior. Linguistic theory has to extend the definition of competence. Competence has to be extended to systemic potential, appropriateness, occurence, feasibility.The goals of Sociolinguistics is

1. the social as well as the linguistic

2. socially realistic linguistics

3. socially constituted linguistics

There are several problems that it's not posing a challenge to traditional linguistics and lacking theoretical goals.

Since sociolinguistics means many things to many people,

What do the ATA interface standards define?

- Data speeds and transfer methods between the drive controller, the BIOS, the chip-sets on motherboard, and the OS

What is splitter?

splitter, sometimes called a "plain old telephone service splitter," is a device that divides a telephone signal into two or more signals, each carrying a selected frequency range, and can also reassemble signals from multiple signal sources into a single signal. Users getting connected to the Internet with Asymmetric Digital Subscriber Line (ADSL) service may, in some cases, have a splitter installed at their home or business. Users elsewhere may be able to get splitterless service (which means that a splitter doesn't need to be installed). For ADSL, the splitter divides the incoming signal into low frequencies to send to voice devices and high frequencies for data to the computer. The telephone company's central office also uses a POTS splitter to send low-frequency voice signals on to the voice telephone network and to send high-frequency data to a Digital Subscriber Line Access Multiplexor (DSLAM) for transmission to the Internet.

What does design loop mean?

I'm not exactly sure of my answer, because i was just asked today by my teacher to research "technology design loops." But so far from my research I've found that its cycle that is much like a the scientific method. The first part is recognising a problem. Then you create a solution or product that will solve the problem. You then test your solution, evaluate the results, and start from the first step again to improve you solution.

Transpose of a matrix?

#include <stdio.h>

#include<conio.h>void main()

{

int a[10][10],rows,cols:");

clrscr();

printf("enter the rows and cols:");

scanf("%d%d",&rows,&cols")

printf("enter the elements into the array:");

for(i=0;i<rows;i++)

for(j=0;j<cols;j++)

scanf("%d",&a[i][j]);

printf("the transpose is:");

for("i=0;i<rows;i++)

{

for(j=o;j<cols;j++)

{

printf("%d",a[j][i]);

}

printf("\n");

}getch();

}

What are the phases and passes of a general language processor?

Language processor consist of two phases

1.Analysis phase

2.Synthesis phase

Language processor pass is the processing of every statement in a source program, or its equivalent representation to preform language processing function

pass 1-It analyses the source program and notes relevant information.

pass 2- It synthesizes the target program

Who wrote the world's first computer program?

In 1938 Berlin, Konrad Zuse and his assistants completed a mechanical binary programmable computer, the theory is based on Boolean algebra. It was later named the Z1.

What is a graphic engineer?

Graphic designers-or graphic artists-plan, analyze, and create visual solutions to communications problems. They decide the most effective way of getting a message across in print, electronic, and film media using a variety of methods such as color, type, illustration, photography, animation, and various print and layout techniques. Graphic designers develop the overall layout and production design of magazines, newspapers, journals, corporate reports, and other publications. They also produce promotional displays, packaging, and marketing brochures for products and services, design distinctive logos for products and businesses, and develop signs and signage systems-called environmental graphics-for business and government. An increasing number of graphic designers also are developing material for Internet Web pages, interactive media, and multimedia projects. Graphic designers also may produce the credits that appear before and after television programs and movies.

The first step in developing a new graphic design is to determine the needs of the client, the message the design should portray, and its appeal to customers or users. Graphic designers consider cognitive, cultural, physical, and social factors in planning and executing designs for the target audience. Designers gather relevant information by meeting with clients, creative or art directors, and by performing their own research. Identifying the needs of consumers is becoming increasingly important for graphic designers as the scope of their work continues to focus on creating corporate communication strategies in addition to technical design and layout work.

Graphic designers prepare sketches or layouts-by hand or with the aid of a computer-to illustrate the vision for the design. They select colors, sound, artwork, photography, animation, style of type, and other visual elements for the design. Designers also select the size and arrangement of the different elements on the page or screen. They also may create graphs and charts from data for use in publications, and often consult with copywriters on any text that may accompany the visual part of the design. Designers then present the completed design to their clients or art or creative director for approval. In printing and publishing firms, graphic designers also may assist the printers by selecting the type of paper and ink for the publication and reviewing the mock-up design for errors before final publication.

Graphic designers use a variety of graphics and layout computer software to assist in their designs. Designers creating Web pages or other interactive media designs also will use computer animation and programming packages. Computer software programs allow ease and flexibility in exploring a greater number of design alternatives, thus reducing design costs and cutting the time it takes to deliver a product to market.

Graphic designers sometimes supervise assistants who carry out their creations. Designers who run their own businesses also may devote a considerable amount of time to developing new business contacts, examining equipment and space needs, and performing administrative tasks, such as reviewing catalogs and ordering samples. The need for up-to-date computer and communications equipment is an ongoing consideration for graphic designers.
