The UNIVAC I was designed as a commercial data-processing computer, intended to replace the punched-card accounting machines of the day. It could read 7,200 decimal digits per second (it did not use binary numbers), making it by far the fastest business machine yet built.

UNIVAC

On November 4, 1952, CBS News used a Remington Rand UNIVAC computer for its presidential election night coverage. Although some predicted a close race between Republican Dwight Eisenhower and Democrat Adlai Stevenson, UNIVAC correctly predicted that Eisenhower would win in a landslide.

UNIVAC, which stood for Universal Automatic Computer, was developed by J. Presper Eckert and John Mauchly, makers of ENIAC, the first general-purpose electronic digital computer. These giant computers, which used thousands of vacuum tubes for computation, were the forerunners of today’s digital computers.

Repeated Wi-Fi studies show that Wi-Fi causes oxidative stress, sperm/testicular damage, neuropsychiatric effects including EEG changes, apoptosis, cellular DNA damage, endocrine changes, and calcium overload.

Answer: Both Wi-Fi (wireless fidelity) and WLAN (wireless local area network) mean the same — they both refer to a wireless network that can transfer data at high speeds.

Yes, this is possible, and the best part is, you don’t even need to be on the internet to get this done. Provided your docked PC and your Android phone are on the same WiFi network, this is totally possible with the help of a few third-party apps.

What to do without internet:

• Read articles offline.
• Listen to podcasts offline.
• Do a “brain dump” writing exercise.
• Come up with a few weeks’ worth of blog topics.
• Interact with other humans.
• Hold an impromptu staff meeting.
• Take some time to relax.
• Make some phone calls.

Home internet may be a need for you if you work from home. However, if you only use your home internet for entertainment, such as browsing social media or playing video games, it is actually a want.

In this article, I will introduce to you some ways through which you can get free internet on your Android without data plan….

• Using VPN For Getting Free Internet.
• Databack App.
• Gigato App.
• KickBit App.
• Swagbucks.
• Mcent.
• HotSpot Finder App.
• FreedomPop.

UNIVAC 1103A

Disadvantages

• The computers were very larger in size.
• They consumed a large amount of energy.
• They heated very soon due to thousands of vacuum tubes.
• They were not very reliable.
• Air conditioning is required.
• Constant maintenance was required.
• Not-portable.
• Costly commercial production.

As the invention of first generation computers involves vacuum tubes, so another disadvantage of these computers was, vacuum tubes require a large cooling system. Very less work efficiency. Limited programming capabilities and punch cards were used to take inputs. Large amount of energy consumption.

Disadvantages of First Generatin of Computer: » The computers were very large in size. » They consumed a large amount of energy. » They heated very soon due to thousands of vacuum tubes. » They were not very reliable.

The major limitations of first generation computers. The operating speed was very low. Power consumption was very high. They required large space for installation.

Get support – First-generation students are more likely to live off-campus, work while taking classes, and be enrolled part-time than their non first-generation counterparts. By becoming involved on campus, you may receive the support you need and begin to feel more integrated with other college students.

ENIAC’s main drawback was that programming it was a nightmare. In that sense it was not a general use computer. To change its program meant essentially rewiring it, with punchcards and switches in wiring plugboards. It could take a team two days to reprogram the machine.

Limitations of second-generation computers were: They used transistors as their main component. They were smaller, faster and more efficient than first-generation computers. They also contained all the components we associate with modern-day computers like printer, memory, disk storage, operating system.

Examples of common and historical third-generation programming languages are ALGOL, BASIC, C, COBOL, Fortran, Java, and Pascal.

Advantage and disadvantages of second-generation computers Also, they were faster in speed, and it could improve accuracy and automation and be able to calculate data in microseconds. The computers made in the second generation were smaller in size and more reliable as compared to first-generation computers.

Along with early advances in magnetic-core memory, transistors led to second generation computers that were smaller, faster, more reliable and more energy-efficient than their predecessors.

Fifth generation computers are intended to work with natural language. These computers are much faster than other generation computers. It is easier to repair these computers. These computers are much smaller in size than other generation computers.
