500 individuals earned a Cisco DevNet certification within 16 days of launching.

500 individuals from around the globe have earned a DevNet certification Within sixteen days of launching the new Cisco DevNet certifications.

DevNet started six years ago with the ambitious goal of creating a community of developers who could innovate and succeed with the programmable infrastructure.  Only a few of Cisco’s products had APIs at that time, and the team knew Cisco and the industry would develop in the next 5 years.

They focused on two audiences:

1) To reskill their loyal networkers so they could fully leverage the networking paradigm that was to come, and

2) To attract new developers and ecosystem partners by giving them a new way to engage with Cisco – through its APIs!

Today, all of Cisco’s products are programmable and have APIs.

Data Processing

Data Processing: This is simply the organising, recording, and handling of data in a meaningful way. Generally, organizations employ computer systems to carry out a series of operations on the data to present, interpret, or obtain information .

The process includes activities like data entry, summary, calculation, storage, etc. Useful and informative output is presented in various appropriate forms such as diagrams, reports, graphics, etc.

Data Processing Cycle

The Data Processing Cycle is a series of steps carried out to extract useful information from raw data.

STAGES OF DATA PROCESSING CYCLE

They are six stages of data processing cycle:

1. DATA COLLECTION: This is the first stage of the data processing cycle, and is very important, as the quality of data collected will impact heavily on the output.

2. DATA COLLATION: This stage involves the preparation and arrangement of the data gathered. Here the collected data is checked for accuracy or verified before inputting in the computer.

3. DATA INPUT: This is the task where verified data is coded or converted into machine readable form so that it can be processed through a computer. Data entry is done through the use of a keyboard, scanner, or data entry from an existing source.

4. DATA PROCESSING: This is the act of arranging and analyzing the inputted data in order to bring out meaningful information.

5.DATA OUTPUT: This is the stage where processed information is now transmitted and displayed to the user through an output device.

6. DATA STORAGE: This is the last stage in the data processing cycle, where data are held for future use.

TYPES OF DATA PROCESSING:

  1. Scientific data processing
  2. Real time data processing
  3. Automatic data processing
  4. Manual Data processing

FEATURES OF DATA PROCESSING AS A TOOL FOR DATA PROCESSING

1. INCREASED ACCURACY: What this means is that computer is that it does not make mistakes

2. SPEED: Computer is very fast. work which 10 or more persons will do in weeks, computer can do them in a few seconds.

3. STORAGE: Computer can store data for as long as possible.

4. HANDLES REPETITIVE TASK: Computer can repeat a thing as many times as possible.

5. MULTITASKING: Computer can do many things at the same time.

HTML – CLIENT SERVER CONCEPT/ PROGRAMMING DNS, TELNETS, AND  FTP

The concept that is widely used in the internet nowadays is client server concept, client server programming etc. most of the internet applications that we use today are based on client server programming.

CLIENT SERVER MODEL

  1. STANDARD MODEL FOR DEVELOPING NETWORK APPLICATIONS.
  2. NOTATION OF CLIENT AND SERVER
  • A server is a process that is offering some service
  • A client is a process that is requesting the service.
  • Server or clients maybe running on different machines.
  • Server waits for waits for request from client(s).
CLIENT

Diagram of client server model

SERVER

CLIENT

 

TYPICAL SCENARIO

The server should be the first process to start. The server process starts on some computer system, initializes itself then goes to sleep waiting for the clients request.

A client  process starts either on same system or a different system, and sends a request to the server. When the server process has finished providing its service to the clients, the server goes back to sleep waiting for the next client request to arrive. The process repeats continuously as long the clients are sending request and the server is sending back the response and so on.

Roles of the client and server processes are asymmetric. However they are two types of servers:

  • Iterative servers: The server is said to be iterative when the server process knows in advance how long it takes  to handle each request and it handles each request itself. Single copy of server  runs at all times. A client may have to wait if the server is busy.
  • Concurrent servers: These servers are used when the amount of time required to handle a request is unknown. The server starts another process to handle each request. A copy of a server caters to a client’s request in a dedicated fashion. As many copies of server as there are client request.

A client server communication can use either TCP or UDP. If the client server is using TCP, then before start of communication, a connection has to be established between the two hosts.

They are five components in a connection.

  • Protocol used
  • Source IP address
  • Source port number
  • Destination IP address
  • Destination port number

DEVELOPING A NETWORK APPLICATION

The best way to use some standard and well accepted protocol is:

  • At the data link layer level, use ETHERNET.
  • At the network layer level, use IP.
  • At the transport layer level, use TCP.
  • At the application layer level, use a standard API Berkeley socket interface.

A socket  is a BSD (Berkeley socket distribution) method for achieving  inter-process communication (IPC). It is used to allow one process to speak to another ( on same or different machine).

DOMAIN NAME SYSTEM (DNS). This is a global database system for internet addressing, mail and other information. It is much easier to use and memorize. DNS server translate domain names to IP addresses.

TOP LEVEL DOMAINS

.com – Commercial

.org – Non – profit

.net – Network service provider

.gov –  US government

.mil – Military

. edu – Education

.au – Australian

.at – Austrian

.ca – Canadian

.dk  – Dutch

.fr – French

.de – German

.in – Indian

.it – Italian

.jp – Japanese

.kr – Korean

.nz – New Zealand

.es – Spanish

.tw – Taiwanese

.uk – British or Irish

.us – US

They are two letter domain for each and every country in the world.

NAME RESOLUTION PROCESS

The most commonly used server is BINDN (Berkeley  internal name domain) it runs under unix as a process called named. When an application needs some information from the server, it invokes the DNS name resolver. DNS translates a fully qualified domain name into the corresponding IP address using the command nslookup.  If the name server does not have the information locally, it asks its primary server and so on. For redundancy each host may also have one or more secondary name servers which maybe queried when the primary fails.

TELNET PROTOCOL

This allows a person sitting on one computer to work on another computer, it starts a remote session on another machine, and requires a person to supply login name and password to gain entry. Using telnet, we are able to log on to another system and use some facility out there. But  you cannot transfer files from one machine to another.

FILE TRANSFER PROTOCOL (FTP)

This allows a person to transfer files between two machines. It requires a person to supply login name and password to gain entry.

A special form of FTP which has become very popular is the anonymous FTP. It does not require a person to know login name and password. Instead in place of login name, type the word anonymous and in place of password, type the email address.

Twitter CEO re-evaluates plans to move to Africa; says tweet about his move was a “mistake”

The Chief Executive Officer (CEO) of Twitter, Jack Dorsey has cancelled his plan to relocate to Africa for up to six months in 2020. Jack described his tweets about moving to Africa as “a mistake”.

 

In November 2019, after visiting Africa on a month-long trip, Dorsey tweeted: “Sad to be leaving the continent … for now. Africa will define the future (especially the bitcoin one!). Not sure where yet, but I’ll be living here for 3-6 months mid-2020. Grateful I was able to experience a small part.”

 

However, Dorsey has now said that he needs to re-evaluates his plans about living in Africa due to the Coronavirus outbreak amongst other things

 

He said this while speaking at an investor conference sponsored by Morgan Stanley.

 

“When I tweeted about my intention to spend a few months in Africa this year, I made a mistake and should have provided more context about why. The continent will be one of the most populated in the next 20-30 years, and room for tech innovation there is incredible, but in light of COVID-19 and everything else going on I need to reevaluate. Either way, we’ll continue to pursue opportunities in Africa.” Dorsey said.

 

Coronavirus aside, Dorsey risks being replaced as Chief Executive Officer of the company he co-founded due to the new activist investors that are currently rooting for his removal.

 

News reports last week said Elliott Management, the activist hedge fund founded by billionaire Paul Singer, a major Republican political supporter, has acquired nearly 5% in Twitter and is now pushing for the removal of Dorsey as CEO, and has nominated four members to Twitter’s board.

 

The firm pushed for the change stating that Dorsey’s attention is divided between running Twitter and his financial transactions startup Square, and that Dorsey intends to live part of each year in Africa.

 

Dorsey said he remained capable of managing the two San Francisco-based tech firms.

 

“I have enough flexibility in my schedule to focus on the most important things and I have a good sense of what is critical on both companies,” he said.
