IBM-PC is an example of

A)

Special purpose

B)

Machine-in-built

C)

A main frame

D)

Micro computer

Correct Answer : Micro computer

IBM-PC is an example of Micro computer. The IBM Personal Computer, commonly known as the IBM PC, is the original version and progenitor of the IBM PC compatible hardware platform. It was created by a team of engineers and designers under the direction of Don Estridge of the IBM Entry Systems Division in Boca Raton, Florida. IBM PC compatible computers are computers similar to the original IBM PC, XT, and AT, able to use the same software and expansion cards. Such computers used to be referred to as PC clones, or IBM clones.

3 .

Hard disks are formatted in the same manner as floppy disks. However, before a hard disk can be formatted, it must first be_____

A)

sectioned

B)

deleted

C)

partitioned

D)

write protected

Correct Answer : partitioned

4 .

Which type of computers use the 8 bit code called EBCDIC?

A)

Mainframe computers

B)

Microcomputers

C)

Minicomputers

D)

Supercomputers

Correct Answer : Mainframe computers

Mainframe computers (colloquially referred to as "big iron") are computers used primarily by large organizations for critical applications; bulk data processing, such as census, industry and consumer statistics, enterprise resource planning; and transaction processing.

5 .

A one-bit signal that indicates the start of data transmission by an asynchronous device is

A)

Start bit

B)

Parity bit

C)

Status bit

D)

Zero bit

Correct Answer : Start bit

A one-bit signal that indicates the start of data transmission by an asynchronous device is Start bit

Parallel devices have a wider data bus than serial devices and can therefore transfer data in words of one or more bytes at a time. As a result, there is a speedup in parallel transmission bit rate over serial transmission bit rate.

In telecommunication and data transmission, serial communication is the process of sending data one bit at a time, sequentially, over a communication channel or computer bus. This is in contrast to parallel communication, where several bits are sent as a whole, on a link with several parallel channels.

Data transmission refers to the process of transferring data between two or more digital devices. Data is transmitted from one device to another in analog or digital format. Basically, data transmission enables devices or components within devices to speak to each other.

6 .

A mechanism for arranging controlled access to a shared resource is

A)

Balleting

B)

Lock-out

C)

Retrieving

D)

Sorting

Correct Answer : Lock-out

7 .

Who is 1988 announced the latest version of CD-ROM called CD-ROMXA (extended architecture) which provides a documented means of integrating digital audio with computer data on a CD-ROM disk?

A)

Sony

B)

Philips

C)

Microsoft

D)

All of the above

Correct Answer : All of the above

A CD-ROM is a pre-pressed optical compact disc which contains data. The name is an acronym which is short for "Compact Disc Read-Only Memory". Computers can read CD-ROMs, but cannot write to CD-ROMs, which are not writable or erasable.

Several formats are used for data stored on compact discs, known as the Rainbow Books. The Yellow Book, published in 1988, defines the specifications for CD-ROMs, standardized in 1989 as the ISO/IEC 10149 / ECMA-130 standard. The CD-ROM standard builds on top of the original Red Book CD-DA standard for CD audio. Other standards, such as the White Book for Video CDs, further define formats based on the CD-ROM specifications. The Yellow Book itself is not freely available, but the standards with the corresponding content can be downloaded for free from ISO or ECMA.

8 .

Which of the following is the expansion of EBCDIC

A)

Extended binary coded decimal information code

B)

Extended bootable computerised digital infrared calculator

C)

Extended binary coded decimal interchange code

D)

Extended bit comparable to digital interface for computer

Correct Answer : Extended binary coded decimal interchange code

Extended Binary Coded Decimal Interchange Code (EBCDIC) is an 8-bit binary code for numeric and alphanumeric characters. It was developed and used by IBM. It is a coding representation in which symbols, letters and numbers are presented in binary language.

Extended Binary Coded Decimal Interchange Code is an eight-bit character encoding used mainly on IBM mainframe and IBM midrange computer operating systems. It descended from the code used with punched cards and the corresponding six bit binary-coded decimal code used with most of IBM's computer peripherals of the late 1950s and early 1960s. It is supported by various non-IBM platforms, such as Fujitsu-Siemens' BS2000/OSD, OS-IV, MSP, and MSP-EX, the SDS Sigma series, Unisys VS/9, Burroughs MCP and ICL VME.

9 .

Computer can not do anything without a

A)

Memory

B)

Program

C)

Chip

D)

Output device

Correct Answer : Program

A computer program is a collection of instructions that performs a specific task when executed by a computer. Most computer devices require programs to function properly.

A computer program is usually written by a computer programmer in a programming language. From the program in its human-readable form of source code, a compiler or assembler can derive machine code—a form consisting of instructions that the computer can directly execute.

10 .

Which of the following is a communication network that is devoted to carrying computer information.

A)

Data network

B)

Data module

C)

Data pack

D)

Data point

Correct Answer : Data network
