8) The UNIX operating system is written in language?
Cobol
C Language
Binary
Fortran
9) C is which level language?
HLL
MLL
LLL
DLL
Explanation:
The C language was known as a High Level Language (HLL) before languages like Java, Perl, Python came in. Some decades ago, the C language, and similar such languages were most often considered "high-level", as it supported concepts such as expression evaluation, parameterised recursive functions, and data types and structures, while assembly language was considered "low-level".
But things have changed over the years. C is often called a middle-level computer language as it combines the elements of high-level languages with the functionalism of assembly language.
High Level Language:
A high-level programming language is a programming language that is more user-friendly, to some extent platform-independent, and abstract from low-level computer processor operations such as memory accesses.
Low Level Language:
A low-level programming language is a programming language that is more machine specific, and from computer processor operations such as memory accesses is directly dependent.
12) The result of an arithmatic and logical operations are stored in?
Accumulator
Instructions register
Cache memory
Rom
Explanation:
Accumulator: In a computer's central processing unit (CPU), an accumulator is a register in which intermediate arithmetic and logic results are stored. Without a register like an accumulator, it would be necessary to write the result of each calculation (addition, multiplication, shift, etc.) to main memory, perhaps only to be read right back again for use in the next operation. Access to main memory is slower than access to a register like the accumulator because the technology used for the large main memory is slower (but cheaper) than that used for a register.Modern CPUs usually have many registers, all or many of which can be used as accumulators. For this reason, the term "accumulator" is somewhat archaic. Use of it as a synonym for "register" is a fairly reliable indication that the user has been around for quite a while and/or that the architecture under discussion is quite old. The term in full is almost never used of microprocessor registers.
Instructions Register: In computing, an instruction register (IR) is the part of a CPU's control unit that stores the instruction currently being executed or decoded. In simple processors each instruction to be executed is loaded into the instruction register which holds it while it is decoded, prepared and ultimately executed, which can take several steps.
More complicated processors use a pipeline of instruction registers where each stage of the pipeline does part of the decoding, preparation or execution and then passes it to the next stage for its step. Modern processors can even do some of the steps of out of order as decoding on several instructions is done in parallel.
Decoding the opcode in the instruction register includes determining the instruction, determining where its operands are in memory, retrieving the operands from memory, allocating processor resources to execute the command (in superscalar processors), etc.
The output of IR is available to control circuits which generate the timing signals that controls the various processing elements involved in executing the instruction.
Cache Memory: A CPU cache is a cache used by the central processing unit of a computer to reduce the average time to access memory. The cache is a smaller, faster memory which stores copies of the data from the most frequently used main memory locations. As long as most memory accesses are cached memory locations, the average latency of memory accesses will be closer to the cache latency than to the latency of main memory.
13) A small amont of memory included in the processor for high speed access is called?
Register
Cache
Ram
Rom
Explanation:
Read in answer above
14) A co-processor is used to?
Enhance main memory
Track errors in the cpu
Improve performance of bussiness application
Improve the speed of mathematical calculation
Explanation:
A coprocessor is a computer processor used to supplement the functions of the primary processor (the CPU). Operations performed by the coprocessor may be floating point arithmetic, graphics, signal processing, string processing, or encryption. By offloading processor-intensive tasks from the main processor, coprocessors can accelerate system performance.
15) The clock frequency of a pentium processor is?
Above 50 MHz
Above 500 MHz
Below 10 MHz
25 MHz
A note:
MHz: Mega Hertz GHz: Giga Hertz
The clock frequency or clock rate of the first Intel Pentium Processor introduced in 1993 was named P5 clocked between 60 to 300 MHz. Pentium II (P6 or sixth generation micro-architecture) introduced in 1997 came with a speed ranging between 233 to 450 MHz while the Pentium III introduced in 1999 was between 400 MHz to 1.4 GHz.Pentium 4 which was introduced in 2000 clocked between 1.3 to 3.8 GHz. So in reality the clock frequency has been above 500 Mhz from Pentium 4 onwards.
Therefore I feel that the correct answer should have been “Above 50 MHz”.
16) The pentium processor contains?
Tens of thousands of transistors
Hundred thousands of transistors
Thousands of transistors
Several millions of transistors
Explanation:The first Pentium processor from Intel Corporation introduced in 1993 consisted of 3,100,000 (or 3.1 million) transistors.
17) In the initial years RISC technology was expensive since?
RISC microprocessor consume more power
It needed expensive packaging
It needed a larger chip
It needed larger memory beside cache memory
Explanation:
RISC stands for Reduced Instruction Set Computing. RISC microprocessors are used in the ARM (Advanced RISC Machine) architecture dominates the market for low power and low cost embedded systems (typically 100–1200 MHz in 2011). It is used in a number of systems such as the Apple iPhone and iPad, RIM devices, etc.
The RISC designs implemented instruction stream and the data stream conceptually separated; this means that modifying the memory where code is held might not have any effect on the instructions executed by the processor (because the CPU has a separate instruction and data cache)
18) Inspite of the extra power needed for refreshing, DRAMs are widely used in computers because
Of the lower cost of bus
Of it is a lower cost relative to SRAMs
Of case of programming
Of it is a higher speed relative to SRAMs
A Note:As I’d explained in class that SRAMs are not easily available now and they are expensive as compared to today’s DRAMs. Though SRAMs were seemingly faster than DRAMs, they used a higher number of transistors as compared to DRAMs. The DRAMs hence were lesser expensive.SRAM – Static RAMDRAM – Dynamic RAMSDRAM – Synchronous Dynamic RAMDDR SDRAM – Dual Data Rate SDRAM
19) Secondary storage device is needed to?
Perform arithmetic and logical operations
Store small volume of data
Print output result
Store large volume of data that exceed the capacity of main memory
20) Which one of the following does not fall under the category of the secondary storage device?
SRAM
Hard disk
Optical disk
Winchester disk
21) Which one of the following medium is universal, portable,and inexpensive but has its own limitations in term of storage capacity and speed?
Hard disk
Winchester disk
Optical disk
Floppy disk
22) In case of Winchester disk the head?
Contacts the recording surface occasionally
Never contacts the disk surface
Always contacts the recording surface
Contacts only the landing area while not recording
A Note:
A kind of hard disk drive. The term Winchester comes from an early type of disk drive developed by IBM that had 30MB of fixed storage and 30MB of removable storage; so its inventors called it a Winchester in honor of its 30/30 rifle. Although modern disk drives are faster and hold more data, the basic technology is the same, so Winchester has become synonymous with hard.
23) Out of the following types of floppy disk, which one has a metal hub?
5.25 inch
3.5 inch
6.25 inch
None
Contradiction:The 3.25 inch is the only one having a metal hub whereas the 8” and 51/4 “ floppy disks have holes in the center. There is no such floppy disk as 6.25” so the right option is 3.25”.
24) In which one of the following types of disk, the read-write head physically contacts the surface of disk while recording?
Optical disc
Floppy disk
Hard disk
CD Rom
Explanation: Optical discs are CDs, DVDs, Blu-Ray Discs. The read/write head of any of the CD/DVD/Blu-Ray Disc ROM drive uses a laser for the operation.
Just a small change regarding CD-ROMsCD ROM means Compact Disc Read Only Memory (You can't write to these discs, and the ones you buy in shops like games and music CD's are pressed and not burned). They are discs which have pre-loaded content.
[CD-R is the blank CD available for writing/burning so that you can create your own content. If multi-session mode is not selected during a burn/write session than the CD-R becomes equivalent to a CD-
ROM. But whatever is written once on a CD-R can’t be erased unlike a CD-RW.]
Hard disk, would be either external or internal hard disks. The read/write head doesn’t touch the surface in the hard disk.
25) A standard magnetic tape reel accommodates?
800 feet of memory tape
400 feet of memory tape
1000 feet of memory tape
2400 feet of memory tape
26) For a storage requirement exceeding one Giga byte, which one of the following system costs the least per mega byte?
Optical disc
Floptical
Floppy disk
Hard disk
A Note:I did a bit of comparison study and this is what I found.Optical Disc: When we talk about optical discs, it includes CDs, DVDs as well as Blu-Ray Discs and other such discs which are read using a laser.Floptical: Floptical refers to a type of disk drive that combines magnetic and optical technologies to store large amounts of data.
Floppy Disk: Could hold small amounts of data.
Hard Disk: Is used to hold huge amounts of data.
Price ComparisonPrices are indicative, not perfect.
CD-R holds 700 MB, cost is around Rs. 10
If we divide the cost with the capacity we’ll get the cost per MB
10/702 = Rs. 0.014/MB
DVD-RCapacity = 4.7GB Cost = Rs 20
20/4.7GBFirst, we need to convert the GB to MB.1GB = 1024MB
Hence, 4.7GB is (4.7 X 1024)MB = 4812.4MB
Hence, 20/4812.4 = Rs. 0.0041/MB
Blu-RayCapacity= 25GB Cost = Rs. 23525 X 1024MB = 25600MB235/25600MB = Rs. 0.0091/MB
FloppyCapacity = 1.44MB Cost = Rs 25
25/1.44MB = Rs. 17.36/MB
Hard DiskCapacity= 1TB (Tera Byte or 1024GB) Cost = Rs 6000
6000/1TB = 6000/1024GB = 6000/(1024 X 1024)MB = 6000/1048576MB
= Rs. 0.0057/MB
So comparing the costs the DVD seems to be the cheapest.The problem seems to be wrongly framed. Reasons:1. DVD should have been specified as an option.2. The prices are different everywhere. How can one be sure of the cost at any one place as there is no standardized rate anywhere in India.
Therefore I feel the problem doesn’t hold a proper answer.

32) Which one of the following key does not have tactile feedback?
Rubber dome
Mechanical
Capacitive
None
Explanation:CapacitiveIn the cell phone industry there are two major categories of touchscreen displays: capacitive touchscreens and resistive touchscreens. Capacitive touchscreen displays rely on the electrical properties of the human body to detect when and where on a display the user touching. Because of this, capacitive displays can be controlled with very light touches of a finger and generally cannot be used with a mechanical stylus or a gloved hand. Examples of devices with capacitive touchscreens are the Apple iPhone and the T-Mobile G1.
Tactile Feedback: Haptic technology, or haptics, is a tactile feedback technology which takes advantage of the sense of touch by applying forces, vibrations, or motions to the user.
Tactile feedback mechanisms respond to touch, simulating a sensation of tapping. The response is accomplished through the use of subtle and textured vibrations. Tactile feedback, however, does not interfere with the operation of the actual device.
How It WorksAn actuator, a small motorlike device, causes the vibration in equipment with tactile feedback. Software known as the haptic player actually controls how intense the actuator vibrates and when it vibrates.
ImplementationsMany touch-screen cell phones provide tactile feedback so users know when they press something on the screen. Tactile feedback also helps when typing as most people are accustomed to a response when pressing keys. Some game controllers also use tactile feedback to enhance a players' interaction with the video game.
Handset manufacturers like LG and Motorola are including different types of haptic technologies in their devices; in most cases, this takes the form of vibration response to touch.
Rubber Dome: is the membrane used under some keyboards to detect which key has been pressed. It operates under the tactile feedback.
Mechanical: also comes under tactile feedback. Older touch screen devices which would respond to any sort of touch, whether hand or stylus come under this category.

42) WINDOWS settings are recorded in?
WINDOWS.INI
CONTROL.INI
SYSTEM.INI
None
Explanation:The INI file format is an informal standard for configuration files for some platforms or software. INI files are simple text files with a basic structure composed of "sections" and "properties".
They are a deprecated standard on the Windows operating system. The use of the "INI file" has been changed in Windows in favor of the registry,
WIN.INI or WINDOWS.INI is a basic INI file that was used in versions of the Microsoft Windows operating environment up to Windows 3.11 (before Windows 95 and onwards) to store basic settings at boot time. By default, all font, communications drivers, wallpaper, screen saver, and language settings were stored in WIN.INI by Windows 3.x. Many of these settings were honored in Windows 9x (Windows 95 onwards), although the files had begun to be phased out in favor of the Windows registry (The Windows Registry is a hierarchical database that stores configuration settings and options on Microsoft Windows operating systems). Windows XP still acknowledges some entries in the WIN.INI file, to provide backwards compatibility with older 16-bit applications. However, when a fresh install of XP is performed, the WIN.INI file created is initially blank, and in Windows Vista and Windows 7 the WIN.INI file was removed entirely.
CONTROL.INI is a file associated with the Microsoft Windows 95, 98, ME, 2000, and XP Control Panel. This file is used to customize and change how the Control Panel operates and what is seen in the Control Panel.
Earlier versions of Microsoft Windows (Windows 95, 98, and ME) also used this file as a configuration file for how windows displays icons and other visual settings, screen saver settings, passwords, and other OS settings. New versions of Windows such as Windows 2000 and Windows XP still create this file for backwards compatibility however apart from hiding Control Panel icons this file is no longer used.
Depending on your version of Windows the control.ini file will be located in either the c:\windows or c:\winnt directory and may or may not have any data within it.
SYSTEM.INI was an initialization (INI file) used in early versions of Microsoft Windows (from 1.01 up to Millenium Edition [ME]) to load device drivers and the default Windows shell (Program Manager or Windows Explorer), among other system settings. Many of these settings were honored in Windows 9x (95, 98 and ME), although the INI files had begun to be phased out in favor of the Windows Registry. Windows NT 4.0, 2000, XP and Server 2003 still acknowledge some SYSTEM.INI entries in order to provide backwards compatibility with older 16-bit applications.
43) All system settings in WINDOWS are stored in?
MAIN.INI
CONTROL.INI
SYSTEM.INI
SETTING.INI
Explanation:For CONTROL.INI & SYSTEM.INI refer above question.MAIN.INI is a worm.SETTING.INI is a file used to handle system settings in Windows.
44) WINDOWS can work in which of the following modes?
