Question 3 options:
A
)
In many file system designs, there are two kinds of fragmentations possible. (i) File content is stored in disk
blocks. File content is seldom an exact multiple of disk blocks, so the last block used is almost never full.
This is known as internal fragmentation. (ii) Large files are almost always stored in non-consecutive blocks
scattered around non-volatile memory. This is known as external fragmentation.
B
)
sudo apt-get update updates the locally stored database of what applications are installed and
what newer versions are now available. sudo apt-get update replaces older applications with
newer ones.

C) In Debian Linux version like Lubuntu, sudo apt-get install
nameOfThePackage installs the package; sudo apt-get remove
nameOfThePackage uninstalls it. The command dpkg -l lists all the packages
installed.
D) In Windows, software is packaged in a file format known as .msi,
and msiexec.exeinstalls such packages. When you double-click on
a .msi file, the Graphical User Interface (GUI) front-end of this
program is invoked by association. The msiexecprogram has
many command-line switches not available through the GUI.

Question 12
Which of the following statements are true?

A) A page fault is a type of fault detected by computer hardware when a running program accesses a memory page that is mapped into the
virtual address space, but not actually loaded into main memory. Software that handles page faults is generally a part of the operating system.
When handling a page fault, the operating system generally tries to make the required page accessible at the location in physical memory or
terminates the program in case of an illegal memory access.
B) A segmentation fault is a type of fault detected by computer hardware with memory protection to notify an operating system (OS) about a
memory access violation. The OS will, in response, usually perform some corrective action, generally passing the fault on to the offending
process or causing abnormal termination of the process.
C) A segmentation fault occurs when a program attempts to access a memory location that it is not allowed to access, or attempts to access a
memory location in a way that is not allowed e.g. attempting to write to a read-only location or fetch an instruction from non-executable
memory.
D) A bus error is a type of fault detected by computer hardware to notify an operating system (OS) that a process is trying to access memory
that the CPU cannot physically address i.e. an invalid address for the address bus. In modern use on most architectures these are much rarer
than segmentation faults, which occur primarily due to memory access violations.
E) Computer applications make a call using the application programming interface (API) to access shared resources, like the keyboard,
mouse, screen, disk drive, network, and printer. These can fail in two ways: Blocked Calls or Faults. A blocked call is a request for services
from the operating system that halts the computer program until results are available. Faults originate from API calls, from the operating
system, and from other applications, and typically, any fault that is not handled by an application causes premature application termination.
Fault-tolerant software continues to meet operational requirements in spite of the possibility of blocking and faults.

Question 18
The terms endian and endianness refer to the convention used to interpret the bytes making up a data word when those bytes are stored in
computer memory or transmitted over a network. In computing, memory commonly stores binary data by organizing it into 8-bit units called
bytes. Each byte has a unique address. When reading or writing a data word consisting of multiple such units, the order of the bytes stored in
memory determines the interpretation of the data word. Endianness refers to the question: Does the most significant byte of a multi-byte word
have a lower address (come first) or a higher address (come after) the least significant byte.
Question 18 options:

True
False
Question 19
Which of the following statements are true.
A) The network access features of operating systems are typically implemented following some variation of the Open Systems
Interconnection (OSI) 7-layer model.
B) An abstraction layer or abstraction level is a way of hiding the implementation details of a particular set of functionality to allow
separation of concerns to facilitate interoperability and platform independence
C) "All problems in computer science can be solved by another level of abstraction ... except for the problem of too many layers of
abstraction."
D) Encapsulation is a method of designing modular communication protocols in which logically separate functions in the network are
abstracted from their underlying structures by inclusion or information hiding within higher level objects. Using encapsulation, each layer of
abstraction adds a header (and sometimes trailer) to the layer above. For example, in the Internet protocol suite, the contents of a web page are
encapsulated with an HTTP header, then by a TCP header, an IP header, and, finally, by a frame header and trailer. The result of
encapsulation is that each lower layer provides a service to the layer or layers above it.
E) In telecommunications and computer networks, multiplexing is a method by which multiple analog or digital signals are combined into one
signal over a shared medium e.g. several telephone calls may be carried using one wire and data packets from many senders may be
sequentially transmitted over a shared wire or radio frequency.

Various distributions organize files slightly differently and provide different

default programs for tasks such as web browsing, email, command line
interfaces, and software development.
D) Linux is an Open Source operating system similar to the famous
Unix operating system.
Question 23
Which of the following statements is true?
A) Without a trusted certificate verifying the identity of a communication partner, a "Man in the Middle" attack is possible even when using
asymmetric key cryptography.
B) For more than one person to decrypt a file encrypted with symmetric key cryptography, it is usually necessary for more than one person to
know the encryption key.

Question 24
Which of the following statements are true?
A) The physical layer defines the means of transmitting raw bits rather than logical data packets over a physical link connecting network
nodes. The bit stream is converted to a physical signal that is transmitted over a hardware transmission medium such as Ethernet or WiFi or
Bluetooth. The physical layer provides an electrical and mechanical interface to the transmission medium.
B) The data link layer transfers data between nodes on the same network. The data link layer is concerned with local delivery of frames that
do not cross the boundaries of a local network. Inter-network routing and global addressing are higher-layer functions, allowing data-link
protocols to focus on local delivery.
C) The network layer is responsible Internet Protocol (IP) packet formation and for packet forwarding including routing through intermediate
routers based on knowledge of the network addresses of neighboring network nodes. IP is connectionless in that a datagram can travel from a
sender to a recipient without the recipient having to send an acknowledgement. Connection-oriented protocols exist at other, higher layers of
the OSI model.
D) The transport layer provides services such as connection-oriented data stream support, reliability, flow control, and multiplexing. The best-
known transport protocol is Transmission Control Protocol (TCP) used for connection-oriented transmissions, whereas the connectionless
User Datagram Protocol (UDP) is used for simpler messaging transmissions.
E) The application layer contains the communications protocols and interface methods used in process-to-process communications across a
computer network. The application layer is implemented in each application as a way of interpreting or decoding payload data transmitted
using other OSI layers. Hyper Text Transfer Protocol (HTTP), File Transfer Protocol (FTP), Simple Mail Transfer Protocol (SMTP), and
Remote Procedure Call (RPC) are all examples of application layer protocols.
F) A protocol is a set of of rules that facilitate communication between two or more entities. Data exchanged has to be evaluated in the
context of ongoing communication, and a protocol defines the data structures and processes used to perform the evaluation.

Question 29
Which of the following statements are true?
A) Most modern operating systems use a hardware Memory Management Unit (MMU) to segment the portions of main memory allocated to
each process. Different memory segments serve different purposes in running programs.
B) The Stack memory is used to hold temporary values, storage for function or method local variables, function or method arguments,
function or method return addresses. Stack memory enables recursive function or method calling.
C) Stack memory is a finite resource, and any program that attempts to use more stack memory than is available experiences a "stack
overflow". Stack overflow is typically a very serious bug that will either corrupt program data or cause a program to terminate abnormally.

D) Static memory may not contain storage for variables that change value as a program executes. That's why it's called "static".
E) Static memory is called "static" because they is a fixed amount of it reserved when a program is loaded into memory, and the amount is
"static" meaning is does not increase or decrease in amount as a program executes.
F) Code segments provide storage for machine instructions. Code segments are often protected so that machine instructions within code
segments may not be modified as a program executes.
G) Operating systems may share code segments between separate processes e.g. there may be only one copy of instructions comprising
standard library functions even if many programs loaded into memory use the library functions.
H) Heap segments store memory that may be dynamically allocated as a program executes. For example, when the "new" key word is used in
Java, it usually indicates that additional memory must be reserved from the Heap.

Question 33
Which of the following statements are true?
A) Machine instructions are numbers that are decoded by a processor. Each instruction typically uses a subset of bits to store an opcode which
identifies the operation to be performed such as adding or multiplying or shifting data bits.
B) Assembly languages typically use human readable words, mnemonics, that have a 1::1 correspondence with the valid opcodes in machine
languages.
C) Each instruction typically uses a subset of bits to identify the operands of an operation such as source and destination registers for
computations.
D) An assembler is a program that translates an assembly language program into a machine language program.
E) A compiler is a program that translates one programming language into another. Some compilers translate high level programming
languages into assembly language that must be processed by an assembler to produce machine language. Other compilers translate high level
programming languages directly into machine language.
F) Java byte codes are a machine language for a virtual machine. To execute a Java program on common computers, the byte codes must be
translated into machine instructions for a real (not virtual) machine.

Question 34
Which of the following statements are true?
A) Translation Look-aside Buffer (TLB) is a memory area that is part of a Memory Management Unit (MMU) used to translate virtual
memory addresses into physical memory addresses.
B) A page table is the data structure used by a virtual memory system in a computer operating system to store the mapping between virtual
addresses and physical addresses.
C) Virtual memory is a memory management technique that maps memory addresses used by a program, called virtual addresses, into
physical addresses in computer memory. An operating system manages virtual address spaces and the association of real memory to virtual
memory. An operating system may provide a virtual address ranges that can exceed the capacity of real memory and allow processes to
reference more main memory than is physically present in the computer.
D) Virtual memory may be used with a paging technique by which a computer stores and retrieves data from secondary storage for use in
main memory. The acts of copying data in a physical page of memory to secondary storage and copying other data from secondary storage
into a physical page of memory is called swapping. Frequent swapping is called thrashing, and it drastically reduces aggregate system
performance.
E) Swapping may be used by Virtual memory systems to change the mapping from virtual memory to physical memory as a process executes
and simulate the availability of more main memory than is physically present in the computer.
