The First Generation of Computers Essay - 1317 Words

DEVELOPMENT OF COMPUTERS The first generation of computer which is from the year 1945 has been relatively large in size and very expensive due to the technology that we have back then. Goes by the name â€Å"Colossus†, it was the very first electronic computer developed. It is programmable, digital, electronic, computing devices. The vacuum tubes or known as thermionic valves is used to perform calculations. It serve as purpose to solve mathematic problem faced by the British military during World War II. Colossus is used to decrypt secret message from the German messages during World War II. However, the existence of Colossus has been kept secret until decades after the war. The first generation of computer were mainly used by the military,†¦show more content†¦As a result, the electronic machinery or the computer itself, has greatly reduced in size. Thus makes it more economical. Compared to the first generation computers, the second generation computers is much more reliable due to the si ze, power consumption and time taken to programmed it has been significantly reduced to cope up with the advanced technology during that era. The first transistor to ever make a way into computer was in 1956, not to be confused with the year 1948, which the invention of the transistor. Even though the introduction of transistor still contribute to significant amount of heat that can subjected the computer to damage, it was far better than using the vacuum tubes like in the first generation computers. The first large scale computers to adapt this transistor technology were the first supercomputer. These computers, which are from IBM were developed for used inside atomic laboratories, which an enormous amount of data could be handled by the computers. However, the performance of this supercomputers is too high and does not attract the business sector to use this type of computers. A few high level languages such as FORTRAN, ALGOL, BASIC and COBOL is introduced to shorten and make use of abbreviation for the programming code for the long and difficult binary codes. The example of the second generation computers are IBM 709, IBM 1400, CDC 6600(Control Data Corporation), TX-0 (Transistorized Experimental Computer), TX-2, and NEACShow MoreRelatedThe First Generation Of Computers886 Words   |  4 Pages One of the first definitions for computers was given to people that performed early mathematical calculations.

Information Security for Integrity and Availability- myassignmenthelp

Question: Discuss about theInformation Security for Integrity and Availability. Answer: CIA stands for confidentiality, integrity and availability is nothing but a guide which can be used for measuring the security of information. Information security generally focus on the idea or logic that how information security can be easily used (Betab Sandhu, 2014). CIA triad can be easily used as a tool for or guide for securing information system and various kinds of networks related to it. CIA is nothing but a model which can be used for achievement of information security. There are large number of factors behind CIA triad like confidentiality, integrity and lastly availability. In ATM machine confidentiality can be easily used for protection of large number of information from any kind of unauthorized access. CIA Triad mainly relates to information security which is used for having control on access to the protected kinds of information (Khan, Hasan Xu, 2015). CIA triad mainly requires proper kinds of information security measures for monitoring and controlling with autho rized use and access of transmission of information. The availability is CIA Triad can be easily used for situation which can be used for focusing on information which is needed in right amount. Availability is nothing but a maintaining of all kinds of components of information system which tend to work properly (Karovaliya et al., 2015). The goal of integrity is nothing but a condition in which information can be easily kept accurate and consistent until and unless certain number of authorization are made. In various kinds of ATM machine confidentiality, integrity and availability is considered to be basic kinds of goals of information security. The entire keypad of a ATM machine generally has ten number of keys (0-9). As directed in the question the thief has broken five number of keys from the keypad. The pin number of a ATM machine generally consist of four number so the thief is bound to select the number from remaining five keys which is available to him. For overcoming the problem and taking right decision in this situation we are making use of permutation and combination from mathematics. 5p4 = 5! / (5-4)! =5! /1! = 5*4*3*2*1/1 =120/1 =120. So the thief is making 120 number of attempts with respect to situation which is provided to him. The answer has been found by making use of permutation technique from mathematics. Biometric authentication can be easily defined as the identification of individual for which is totally based on distinguishing of physiological and behaviors relate to characteristics. Biometric identification is considered to be more reliable and it is more capable of traditional based token and knowledge depended technologies which is mainly used for differentiation between authorized and fraudulent kinds of person (Onyesolu Okpala, 2017). There are large number of issues which can be easily encountered is biometric systems. Various kinds of attacks generally exist to have an unauthorized kinds of access to a particular kinds of situation which can be used for gaining unauthorized kinds of access to a system which is protected by a biometric authentication. There are large number of issues which can be dealt with biometric authentication. Biometrics is generally considered to be associated with security and biometric system is considered to be reasonably secure and full of trust. There are some kinds of issues in biometric security. The issues are Proper kinds of sensors and unauthorized acquisition of samples of biometric. Proper kinds of communication between various sensors, matchers and database of biometric. Issues related to accuracy. Issues of various kinds of speeds Issues of cost like biometrics equipments are generally considered to be expensive in nature. There are certain number of issues like privacy. Issues in Authentication or Identification Authentication is nothing but a verification of a user identity who they claim to be. For this possible case the user generally provides a list or range of users (Koteswari Paul, 2017). After that authentication mechanism is mainly used for authentication kinds of mechanism for analyzing the identity of an individual. In comparison identification is not all compared with any kinds of identity. Instead of that speed is provided with credentials. Failure rates Failure rates are generally considered to be in the configuration and day to day of running of a biometric system (Pathak et al., 2015). There are mainly two kinds of failure rates like acceptance rates, false rejection rates. False negative rates are nothing but a situation in which a particular kind of biometric fails to recognize the authenticity of a particular person (Mondal, Deb Adnan, 2017). Based on a particular kind of situation there can be consequences like personals which makes use of a particular kind of parameter for accessing or safeguarding of a whole kind of a thing (Singh Kaur, 2016). On the level of organization, it can easily shut down the whole kind of infrastructure for safeguarding the whole thing. On the level of organization, it can easily shut down the whole kind of kinds of infrastructure. It can easily shut down the various kinds of things which is needed by data centers which can be used for restoring various kinds of services.

When entering the interview room, I tried not to show my nervousness and control my anxiety by putting a smile, talking in an appropriate tone. I sat down in an open and attentive posture in order to impress the panel members. During my interview process, I used good communication skills such as verbal and non verbal communication, maintained good eye contact and used appropriate gestures where applicable, as well as paying equal attention to all the members in order to create a broader picture. Furthermore, I kept my answers clear, short, precise and straight to the facts in order to avoid rambling and getting of the track.

This could be improved by practicing interview skills, being your self and having exposure to more relevant knowledge in that area. I also felt that the content of the information I gave was inadequate and may not be recognised by the panel members as succinct enough to answer their questions. Interviewer’s reflection The interview panel member explained the procedure of the interview to give an overall picture of the interview process. The interview panel created a friendly and welcoming environment which helped to reduce the anxiety level in the interviewee, and also interview was conducted in a professional manner by using appropriate language and questions relevant to the job advertised. All the questions were asked at a regular pace and the interviewee was given ample time to respond to the questions. The interviewee was given opportunity to raise any issues of concern regarding the interview. Note taking during the interview process enabled the interviewers to reflect on the answers given by the interviewee to determine the grades awarded at the end of the interview. Use of open ended questions during the interview process helped to assess the knowledge of the interviewee. All the panel members used appropriate facial expressions as well as good gestures to maximise the interviewee’s response to the questions. Despite the success of the interview, we had some issues of concern during the interview process. We had feelings that some of the questioning was too fast and hard to comprehend by the interviewee. We felt that the tone of the voices might not be clear to the interviewee due to cultural differences of the panel members. The panel members and the interviewee felt that the interview may have been more successful if the group had implemented a rehearsal prior to undertaking the video taped interview. The panel members also felt that it would have been more appropriate if we added more questions to assess the candidate’s level of competence. Conclusion The interview was conducted in a relaxed and professional atmosphere which foster understanding between the candidate and the interviewers. The interviewee showed keen interest as the right candidate for the job through professional presentation and verbal response. Reflecting on the thoughts, feelings and performance of the interview will help to improve the preparation for the real life interviews in future.
