Process description is meant for conveying different type of information related to a particular process. When certain resources have been allotted to a process, the process description also tells the user that which resources have been allotted to a process.

• A computer system consisting of a combination of analog and digital computer systems.
• The digital component normally serves as the controller and provides logical and numerical operations, while the analog component often serves as a solver of differential equations and other mathematically complex equations.

FTP is better than HTTP as it has built in flow control. The control channel and data channels are independent of each other, the separate TCP connections.

FTP is a two way systems as files are transferred back & forth between file server & workstation. Whereas http is a one way system as files are transported only from the web server onto the workstation’s browser.

The correct answer is Data warehouse

Important Points

• A data warehouse is basically a non-volatile collection of information. This is used to help the management reach out to certain significant decisions that are subjective or it can also be used to analyze a certain field.
• In other words, data warehousing is the electronic storage of a large amount of information by a business or organization. Data warehousing is a vital component of business intelligence that employs analytical techniques on business data.
• The concept of data warehousing was introduced in 1988 by IBM researchers Barry Devlin and Paul Murphy. The need to warehouse data evolved as computer systems became more complex and handled increasing amounts of data. A key book on data warehousing is W. H. Inmon's "Building the Data Warehouse," which was first published in 1990 and has been reprinted several times since.

Additional Information

• Data warehouses use a different design from standard operational databases. The latter is optimized to maintain strict accuracy of data at the moment by rapidly updating real-time data. Data warehouses, by contrast, are designed to give a long-range view of data over time. They trade off transaction volume and instead specialize in data aggregation.
• Disadvantages: Data warehouses are expensive to scale, and do not excel at handling raw, unstructured, or complex data. However, data warehouses are still an important tool in the big data era.

The correct answer is "4 Byte".

Key Points

• The size of an IP address is 32 bit or 4 Byte.
• IP address contains 4 octets where each octet is separated by .(dot).
• IP Address is either four-byte (IPv4) or Sixteen-byte (IPv6) addresses.
• A device attached with IP Address can retrieve by RARP protocol.
• IP Address operates in the network layer.
• IP Address identifies the connection of the device on the network.
• IP Address modifies with the time and environment.
• IP Addresses can be found by a third party.

Additional Information

Let's take an example-

10.1.2.3 (a decimal form of IP address)

Binary Equivalent of the above number will be-

00001010.00000001.00000010.00000011

here, we can see 4 Octet separated by Dot Operator.

With this 32 bit IP address, we can actually generate 2^32 IP Addresses.

Which is Approximately more than 4 Billion Addresses.

The correct answer is Multipoint.

• A multipoint connection is a link between three or more devices. It is also known as Multi-drop configuration.
• The networks having multipoint configuration are called Broadcast Networks. In broadcast network, a message or a packet sent by any machine is received by all other machines in a network.
• The packet contains an address field that specifies the receiver.
• Upon receiving a packet, every machine checks the address field of the packet.
• If the transmitted packet is for that particular machine, it processes it; otherwise, it just ignores the packet.
• A point-to-point connection refers to a communications connection between two communication endpoints or nodes. An example is a telephone call, in which one telephone is connected with one other, and what is said by one caller can only be heard by the other.
• A network consists of two or more computers that are linked in order to share resources (such as printers and CDs), exchange files, or allow electronic communications.

A relational database is a collection of data items organized as a set of formally - described tables from which data can be accessed or reassembled in many different ways without having to reorganize the database tables.

     Database terminology

• hierarchical model: represents data as a hierarchical tree structure
• instance: a record within a table
• network model: represents data as record types
• relation: another term for table
• relational model: represents data as relations or tables
• set type: a limited type of one to many relationships

An algorithm is an unambiguous specification of how to solve a class of problems. A flowchart is a type of diagram that represents an algorithm, workflow or process, showing the steps as boxes of various kinds, and their order by connecting them with arrows. This diagrammatic representation illustrates a solution model to a given problem.

The correct answer is Cipher.

Key Points

• Cipher is an algorithm for performing encryption or decryption—a series of well-defined steps that can be followed as a procedure.
• A cipher suite uses one algorithm for encryption, another algorithm for message authentication, and another for key exchange.
• This process, embedded in protocols and written in software that runs on operating systems and networked computer systems, involves public and private key generation for data encryption or decryption, digital signing and verification for message authentication, and key exchange.
• Cipher is an algorithm for performing encryption or decryption—a series of well-defined steps that can be followed as a procedure.
• Ciphers used two important types of transformation:
• Transposition ciphers, which keep all the original bits of data in a byte but mix their order.
• Substitution ciphers, which replace specific data sequences with other specific data sequences

The correct answer is Downloading

Important Points

• 'Downloading' is essentially retrieving data – music, text, images, or other information – from a source on the internet and save it to your computer. It usually involves a process as simple as clicking on a link and following instructions.

Key Points

• Sometimes abbreviated as DL, D/L, or DLing, download is a term used to describe copying data from one computer to another, either over a network or modem. For example, each time you visit a web page on the Internet, you download the information on the page, including any pictures, to your computer. The term download is often associated with pictures, songs, videos, and programs.
• Many new computer users inappropriately refer to copying files on their computer as downloading. When copying a file from your computer to another drive or folder on the same computer, you're copying that file and not downloading the file. If you're copying a file from a different computer to your computer, you're downloading the file.
• Uploading is the process of putting web pages, images, and files onto a web server.
