A. Apple launched the Apple Macintosh in 1984. Microsoft later came out with Windows. 19. One of the ideas used in the development of ARPANET - splitting information into blocks and reassembling them at their destination - came from the Rand Corporation. The initial concept began in relation to what
The operating system is an essential component of the system software in a computer system. 3) C.P.U-(central processing unit) is the hardware within a computer that carries out the instructions of a computer program by performing the basic arithmetical, logical, and input/output operations of the system. 4) KB-(kilobyte) is a multiple of the unit byte for digital information. The SI prefix kilo- means 1000. 5) MB- (megabyte) is a multiple of the unit byte for digital information.
Rodan-222, a radioactive isotope sometimes fund in people’s basements has half-life of then 4 days. The shorter the half-life, the active appearing the atom is. For example, a test tube containing a gram of Rn-222 will cause a Geiger counter to click a raster rate then a gram of U- 238 because more atoms are changing per second. In our lab we will calculate the half-life of Ba-137m. This metastable radioactive isotope has a half-life of less than 5 minutes and is made from the radioactive decay of Cs-137 in a mini-isotope generator.
Stafone Jefferson Unit4Assignment1 Motherboard specifically refers to a PCB with expansion capability - the board is the "mother" of all components attached to it, which often include sound cards, video cards, network cards, hard drives or other forms of persistent storage, TV tuner cards, cards providing extra USB or Firewire slots, and a variety of other custom components. A motherboard provides the electrical connections by which the other components of the system communicate. Unlike a backplane, it also contains the central processing unit and hosts other subsystems and devices. Motherboard Most important consideration * Motherboard CPU Size and Shape * Determined by form factor ATX Form Factor * Replaced older AT form factor * Smaller * Better Organization * Easier to work on * Support for variety of I/O Devices Soft Power Switch * Front of Computer * Does not immediately cut power * Allows Normal OS shutdown process Power Switch * Back of computer * Immediately kills all power Wake on LAN * Configured in CMOS * Keyboard * Network Activity
INTEGRATED CIRCUIT TECHNOLOGY (1961-PRESENT) An integrated circuit which is also known as (microchip, chip, IC) placed transistors, capacitors, resistors, and wiring circuitry, which was separated previously, onto the semiconductor material of a single chip (Germanium or Silicon). The cost of making electronics was greatly reduced due to the integrated circuit, which impacted the designs of all future computers and other electronics. AMD and Intel, two major microprocessor companies, dominate computers of today. The latest available offerings from Intel as an example contains transistors into the billions and compare this to the 1971 Intel 4004 chip, it contained 2,300 transistors. The Pentium chip which is the most common 1993 chip from Intel contained 3,100,000 transistors.
CIS 105 Week 3 DQS CIS 105 DQ 1 There are a variety of computers available, from the smallest computer in a domestic device to the supercomputers used in industry. Despite the different uses for computers, they all have basics elements in common—each computer system involves hardware, software, data, and users. Think about the role of each component of your home or work computer: How do the components of your computer system interact within the system? What improvements or additions to your system do you think would benefit you or make the system more user-friendly?
5. Check your memory How much RAM do you have? Is your system consuming all or most of your RAM? Does the system page out to disk? If so, you’re suffering a massive performance hit, which can be solved by adding more memory to your PC.

Semester 1 MIT101 – Fundamentals of IT & Programming– 2 Credits Assignment Question 1 - Give the classification of computers and explain them briefly ? Ans:- Computers are classified according to their data processing speed, amount of data that they can hold and price. Generally, a computer with high processing speed and large internal storage is called a big computer. Due to rapidly improving technology, we are always confused among the categories of computers. Depending upon their speed and memory size, computers are classified into following four main groups.
With the technology from the 1950s I wonder what my life would look like compared to today? At this moment I have many technological items such as a Television, a cellular phone, maybe a computer, etc., etc. but in the 1950s not that many people had such a privilege to even own a quarter of what I have today. Some men and women back then were lucky to own one television because it was new and started to get popular and the only type of cellular device they had was a home corded phone. Even right now I am writing this essay on a digital computer that is roughly about two feet in dimensions, which can hold around 60GB of data that probably costs $300 while the best computer they had in the 1950s was as big as two refrigerators put together, held 5MB of data and cost around $10,000 per
