In the simplest terms, cloud computing means storing and accessing data and programs over the Internet instead of your computer's hard drive. The cloud is just a metaphor for the Internet.

As infrastructure is off-site (typically provided by a third-party) and accessed via the Internet, users can connect from anywhere. Maintenance of cloud computing applications is easier, because they do not need to be installed on each user's computer and can be accessed from different places.

In cloud computing, the word cloud (also phrased as "the cloud") is used as a metaphor for "the Internet," so the phrase cloud computing means "a type of Internet-based computing," where different services — such as servers, storage and applications — are delivered to an organization's computers and devices

Open System Interconnect by ISO in 1984 - A 7 LAYER MODEL
The OSI, or Open System Interconnection, model defines a networking framework for implementing protocols in seven layers. Control is passed from one layer to the next, starting at the application layer in one station, proceeding to the bottom layer, over the channel to the next station and back up the hierarchy.
Easy Way to Remember the OSI 7 Layer Model
All People Seem to Need Data Processing or Please Do Not Throw Sausage Pizza Away

Special thanks to M. Watkins
Application(Layer 7) This layer supports application and end-user processes. Communication partners are identified, quality of service is identified, user authentication and privacy are considered, and any constraints on data syntax are identified. Everything at this layer is application-specific. This layer provides application services for file transfers, e-mail, and other network software services.

Presentation(Layer 6) This layer provides independence from differences in data representation (e.g., encryption) by translating from application to network format, and vice versa. This layer formats and encrypts data to be sent across a network, providing freedom from compatibility problems. It is sometimes called the syntax layer.

Session(Layer 5) This layer establishes, manages and terminates connections between applications. The session layer sets up, coordinates, and terminates conversations, exchanges, and dialogues between the applications at each end. It deals with session and connection coordination.

Transport(Layer 4) This layer provides transparent transfer of data between end systems, or hosts, and is responsible for end-to-end error recovery and flow control. It ensures complete data transfer.

Network(Layer 3) This layer provides switching and routing technologies, creating logical paths, known as virtual circuits, for transmitting data from node to node. Routing and forwarding are functions of this layer, as well as addressing, internetworking, error handling, congestion control and packet sequencing.

Data Link(Layer 2) At this layer, data packets are encoded and decoded into bits. It furnishes transmission protocol knowledge and management and handles errors in the physical layer, flow control and frame synchronization. The data link layer is divided into two sublayers: The Media Access Control (MAC) layer and the Logical Link Control (LLC) layer. The MAC sublayer controls how a computer on the network gains access to the data and permission to transmit it. The LLC layer controls frame synchronization, flow control and error checking.

Physical(Layer 1) This layer conveys the bit stream - electrical impulse, light or radio signal -- through the network at the electrical and mechanical level. It provides the hardware means of sending and receiving data on a carrier, including defining cables, cards and physical aspects.

Understanding different dimensions of CSE is part of the necessary skill set for an educated person in the 21st century. Whether you want to be a scientist, develop the latest killer application, or just know what it really means when someone says “the computer made a mistake”, studying CSE will provide you with valuable knowledge.

2. Expertise in CSE enables you to solve complex, challenging problems.
CSE is a discipline that offers rewarding and challenging possibilities for a wide range of people regardless of their range of interests. CSE requires and develops capabilities in solving deep, multidimensional problems requiring imagination and sensitivity to a variety of concerns.

CSE will provide you with a foundation of knowledge, problem solving and logical thinking that will serve as a competitive advantage to you in your career, in whatever field you choose.

Operating Systems

A CPU generates 32-bit virtual addresses. The page size is 4 KB. The processor has a translation look-aside buffer (TLB) which can hold a total of 128 page table entries and is 4-way set associative. The minimum size of the TLB tag is:
(A) 11 bits
(B) 13 bits
(C) 15 bits
(D) 20 bits

Answer: (C) 

Explanation: Size of a page = 4KB = 2^12
Total number of bits needed to address a page frame = 32 – 12 = 20
If there are ‘n’ cache lines in a set, the cache placement is called n-way set associative. Since TLB is 4 way set associative and can hold total 128 (2^7) page table entries, number of sets in cache = 2^7/4 = 2^5. So 5 bits are needed to address a set, and 15 (20 – 5) bits are needed for tag.

Consider data given in the above question. What is the minimum number of page colours needed to guarantee that no two synonyms map to different sets in the processor cache of this computer? (GATE CS 2013)
(A) 2
(B) 4
(C) 8
(D) 16


Answer: (C)

Explanation:
1 MB 16-way set associative virtually indexed physically tagged cache(VIPT). 
The cache block size is 64 bytes.

No of blocks is 2^20/2^6 = 2^14.

No of sets is 2^14/2^4 = 2^10.

VA(46)
+-------------------------------+
tag(30) , Set(10) , block offset(6)
+-------------------------------+

In VIPT if the no. of bits of page offset = 
                  (Set+block offset) then only one page color is sufficient.

but we need 8 colors because the number bits where the cache set index and 
physical page number over lap is 3 so 2^3 page colors is required.(option 
c is ans). 

Virtual memory is
(A) Large secondary memory
(B) Large main memory
(C) Illusion of large main memory
(D) None of the above

Answer: (C) 

Explanation: Virtual memory is illusion of large main memory.
