UNIT 1 ASSIGNMENT 1 1) R.A.M- Stands for (random access memory). This is a type of computer memory that can be accessed randomly. RAM is the most common type of memory found in computers and other devices. 2) O.S.-(operating system) is a collection of software that manages computer hardware resources and provides common services for computer programs. The operating system is an essential component of the system software in a computer system.
Which of the following terms represents one trillion bytes of data?- Terabyte 3. Which printers are usually used in offices and classrooms because they print faster and produce high-quality printouts?- Laser printers 4. A large, expensive computer that supports hundreds of users simultaneously is a(n)- mainframe 5. The _______ is the main circuit board that contains the central electronic components of the computer. -Motherboard 6.
If so, you’re suffering a massive performance hit, which can be solved by adding more memory to your PC. 6. Go solid state Solid state is all the rage these days, and with good reason. It’s fast! More and more laptops and even desktops are moving to the technology because of the performance benefits.
DSO = Receivables / Ave. sales per day Receivables= DSO * Ave. sales per day = 20 * 20,000 Receivables= $400,000 (3-2) Debt Ratio: Vigo Vacations has an equity multiplier of 2.5. The company’s assets are financed with some combination of long-term debt and common equity. What is the company’s debt ratio? Debt ratio = 1 – (1 / Equity multiplier) Debt ratio = 1 – (1/2.5) = 1 - .40 = .60 Debt ratio = 60% (3-3) Market/Book Ratio: Winston Washers’s stock price is $75 per share. Winston has $10 billion in total assets.
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.
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.
The concept of virtual memory is one of the very powerful aspects of memory management (Natarajan, 2008-2014). With virtual memory the computer shows to have more memory than it actually has. In Linux, kernel space is constantly present and maps the same physical memory in all processes (Duarte, 2009). This brings us to determine which ways Windows and Linux are different in memory management. Windows has a Virtual memory manager (VMM) and avoids allocating all the memory until it is absolutely necessary.
Chapter 2: 1. What are the advantages of a virtualized data center over a classic data center? 2. An application specifies a requirement of 200 GB to host a database and other files. It also specifies that the storage environment should support 5,000 IOPS during its peak workloads.
2. Determine if the CMOS still utilizes RAM, requiring a battery on the motherboard, or has evolved into using EEPROM. There are still CMOS that use a battery on the mother board but EEPROM is more popular today. CMOS has since evolved from using a RAM to using EEPROM. It's a long name for a small chip that holds bits of data code that can be rewritten and erased by an electrical charge, one byte at a time.
Background of the Kittyhawk project In early 1990, Hewlett Packard’s (HP) Disk Memory Division (DMD) leaded by Bruce Spenner, held a profitable piece of the market with its high-performance 5.25- and 3.5-inch disk drivers and sales of $519 million (by 1992). Although HP’s DMD had not introduced 2.5-inch drive at all, as competitors within that market were too strong to attack directly, by 1991 Spenser was convinced that new disk-drive architecture with an innovative design could take the computing market by storm and that HP was the company to create it. In June1992, HP presented “Kittyhawk” - the world’s smallest hard drive which has 1,3 diameter and had 20 Mg of storage. Moreover, the drive had a number of unique technologies, including low power consumption and ability to withstand 3-foot fall without data loss. However, despite its significant characteristics, by middle 1994, “Kittyhawk” had failed to meet its targets.
