Q1. What is Computer?
A. Computer is an electronic device which converts data into useful information.
Q2. Explain a few of the different ways in which computer can be categorized?
A. Computer can be categorized in the following ways.
1. Main frame computer.
2. Super computer.
3. Minicomputer.
4. Micro computer.
Q3. List six type of computer that are designed for use by a single person?
A. Six types of computers that are designed for use by a single person are
Desktop computers, workstations, notebook computers, tablet computers,
Handheld computers and smart phones
Q4. Describe the two common designs for desktop computers.
A. The more traditional desktop model features a horizontally oriented system
Unit, which usually lies flat on the top of the user’s desk. Many users place
their monitor on top of the system unit. Vertically oriented tower models
have become the more popular style of desktop system. This design allows
the user to place the system unit next to or under the desk, if desired.
Q5. How much do notebook computers typically weigh?
A. Notebook computers generally weigh less than eight pounds, and some even
weigh less than three pounds.
Q6. List four types of computers that are designed for use by organizations, and are commonly used by multiple people at the same time.
A. These computers include network servers, mainframes, minicomputers, and
Supercomputers.
Q7. Why are mainframe systems usually limited in the number of tasks they perform?
A. By limiting the number of tasks the system must perform, administrators
preserve as much power as possible for required operations.
Q8. What is the most popular use for home computers?
A. Electronic mail (e-mail) continues to be the most popular use for home
Computers.
Q9. How are computer technologies used by the military?
A. Some of the world’s most sophisticated computer technology has been
developed primarily for use by the military. In fact, some of the earliest
Digital computers were created for purposes such as calculating the
trajectory of missiles. Today, from payroll management to weapons control,
The armed forces use the widest array of computer hardware and software
Imaginable.
Q10. How are computer technologies being used to train surgeons?
A. New virtual-reality technologies are being used to train new surgeons in cutting-edge techniques, without cutting an actual patient.
Q11.How are analog computers different from digital computers?
A. Analog computers (there are still some out there) use linear combinations of voltage amplitude (or currents or frequencies or phases) from the inputs to determine the required output sequence; digital computers use two-state variables that are either "on" or "off" (true or false, 1 or 0, yes or no) as logical building blocks to derive a digital output sequence from the digitized input. Digital signals may also be converted to analog, and vice versa, so you could have a series of a/d converters, a digital computer, and d/a converters to simulate an analog computer, or a communication channel, as in digital telephones.
Q12. What is the work station? Write down its features.
A. A computer that is generally manufactured to accomplish the task of the professionalism in the field of the computer technology is called as the work station. But the actual definition of the work station is that the computer that is generally developed to run different type of heavy and the professional software for the sake of networking and other important tasks also by the single user is called as the work station. Such computers are less powerful as compared to other typical desktop computer but it has more space to do working if compared with personal computer
.
Important Features Of WorkStation:
There are many important characteristic features of the workstation because it has ability to store more and can run more applications as compared to the typical work computer. Some pf ten specific and the important features of the work stations are as follows1.
The work station has very compact designed as compared to the other personal computers but it has more capacity to save the applications but it has low power compatibility.2.
Typical working computers can only do the simple calculations or the problems but the work station can able to solve the complex and difficult problems that re the big task for three very user to do. So users can do such calculations quit conveniently.3.
One of the great features of the work station is that users can conveniently build three directional models of digital nature that can operate over high power.
Q13.
How does a dump terminal differ from an intelligent an terminal?
A. A dumb terminal has no local processing capabilities of its own. The computer it is working from could be in another room. An intelligent terminal has local processing capability, so it does more than just act as a way of displaying things. Most old mainframe computers are attached to dumb terminals, enabling one computer to be used by many people. A PC is an intelligent terminal. It can be linked to a mainframe too, acting as a dumb terminal then, but it can be used as a standard computer too.
Q14.
What is a midrange computer? Why is it called so?
A. It is small powerful multiuser system with excellent memory capabilities and processing speed. It is less powerful than a mainframe computer but more powerful than a PC. It is just half of the mainframe computer in which approximately 50 terminals can be connected and work at the same time. It is frequently used for middle level organization. Because it lies between mainframe and PC, so it is called midrange computer.
Q15.How is computer technology used in education?
A. The Education & Computer Technology is a valuable source of information for educators, parents and students who use technology to enhance learning. As educators, we must be positive role models for our students. Students must see teachers as proficient users of technology in the classroom. Teachers must provide opportunities for students to access the Internet and the World Wide Web to develop high-quality activities with hands-on use of current technology.
