a. 8 bits per double word b. 32 bits per word c. 64 bits per quadruple word d. 4 bits per byte 4. Which of the following answers are true about random-access memory (RAM) as it is normally used inside a personal computer? (Choose two answers.)
Next tool on our list is the disk defragmenter tool. This tool moves the clusters of a hard drive to make one continuous cluster. When a program is deleted off of a machine is fragments the harddrive leaving the clusters in different parts of the harddrive when a defrag is ran it takes all the fragmented clusters and makes them all one. You can run this manually by performing the following steps. Click Start, and then click Computer.
d. Kilobyte 3. Which answer lists the correct number of bits associated with each term? c. 64 bits per quadruple wor 4. Which of the following answers are true about random-access memory (RAM) as it is normally used inside a personal computer? (Choose two answers.)
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.
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.
| RANDOM ACCESS MEMORY (RAM) | 4 GB (8 GB max) | Gives storage space for data to be downloaded to PC. | ADAPTERS | | Sound cards | Get audio, video, and memory storage. | | | Video cards | | | | SD memory cards | | PORTS | Serial (1), Ethernet (1), and USB (5) | Send and receive information. | STORAGE | Hard Drive | Hard drive (1 x 750 byte); flash drive | Store data even when PC is turned off. | | Optical Drive | CD/DVD drive | | Application Software Table APPLICATION | MANUFACTURER | REQUIREMENTS MET | Word processing; spreadsheets; presentations | Microsoft Word, Excel, Powerpoint, | Create and edit documents; make spreadsheets; create presentations.
The Socket AM3 Connector is used with the following processors. Phenom II Athlon II Sempron Opteron 138x Task 3 1. Use the Internet to locate information on the Intel processors listed in the following table. Fill in all the column values. Processor | Clock Speed | Internal Cache | Bus Speed | Architecture | i7 | 3.4 Ghz | 4MB | 5GT/s | Broadwell
6.Synchronous DRAM, a type of DIMM memory that synchronizes itself with the computer’s system clock to provide a synchronization between the memory and the computer processor. 7. The primary benefit of DDR3 is the ability to transfer I/O data at eight times the speed of the memory cells it contains. DDR3 standard allows for chip capacities of 512 megabits to 8 gigabits, effectively enabling a maximum memory module size of 16 gigabytes. 8.
In operating systems, memory management is used to block individual memory change user’s demand. In the application, memory management is ensures that there is adequate memory for object and data structure for each running program. There are five requirements that memory management have. The four requirements are relocation,
Unit 7 Assignment 1: Video Summary 5 Explain BIOS: Basic Input/ Output System * BIOS tells the hardware how to operate with the computer’s Operating System * BIOS is built into the motherboard and is standard on all computers * BIOS can be used to tune the computer’s hardware * A specialized key stroke is used to enter into BIOS before the system fully boots up * BIOS can only be navigated using key strokes (mouse will not work) * The first Tab shows the different types of internal hardware connections your computer has, IDE and SATA, along with what is connected to them (i.e. DVD Rom drive, hard disk) * Under Advanced Tab, CPU configurations can be changed if options are available (i.e. overclocking) * Under Power Tab, outputs are shown for power outputs of hardware devices (i.e. voltages used and cooling fan speeds, and temperatures of hardware * Under Boot Tab, you are allowed to set up the sequence in which the computer will boot up from (i.e. hard drive, CDROM, or Removable) * Under Exit Tab, You are given the option on how to exit from BIOS with or without saving changes Explain POST: Power On Self Test * POST is a test to determine a computer’s hardware is not faulty before it boots * When a problem occurs BIOS will register an error * A sound messaging speaking is located on the motherboard that will issue a series of beeps when a problem is found.
