If the BIOS finds any errors during the POST, it will notify you by a series of beeps or a text message displayed on the screen. If the primary system BIOS is damaged, and there is a secondary BIOS, you can switch to the secondary BIOS. If you use the wrong Flash BIOS file to update your BIOS, or if the update process doesn’t finish, your system can’t start. You may need to contact the system or motherboard maker for service. Purchasing a replacement BIOS chip may also be an option.
· The ROM BIOS stores the first instruction, which is the instruction to run the power-on self-test (POST). · POST begins by checking the BIOS chip and then tests CMOS RAM. · POST checks the hardware devices (such as the video card), secondary storage devices, such as hard drives and floppy drives,
Which of the following answers best describes how a hard disk drive physically writes a binary 0 or 1?C. changing the disk’s surface 12. Which of the following answers are true about an internal hard disk drive (HDD) as it is normally used inside a personal computer (choose 2) B. used for long-term memory, D. connects to the CPU over a bus using a cable
6. (TCO 3) What type of RAM do most motherboards use today? RIMM Rambus SAMM DIMM 7. (TCO 3) To help secure a computer, you can set a startup or “power-on” password so that the startup BIOS will ask for the password during the boot process. This password is stored in _______.
By proper end user training for anyone involved with the Corporate Techs site, proper scanning of all USB and thumb drives on a test computer being used for this particular site, can mitigate threats from bugs and viruses. Also, by changing all local computer default autorun policies, will disable usage of these USB ports and stop an occurrence from taking place. Last, it’s almost near impossible for an end user to not use a personal laptop during work hours for personal use or for work. But to mitigate further problems from happening, I will implement an encrypted file system for sensitive data. TrueCrypt is a program that I have found efficient that controls over endpoints that enter and exit the internal system.

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.
To: Valerie Bernier, Dentist RE: Can I upgrade the office? Ms. Bernier, After reading your email I have a few questions for you about the systems in question. If each of the systems has 16 GB of available hard disk space then your machines may meet the minimum hardware requirements to install the Windows 7 program. Each system in question need to have a processor speed of 1 GHz or faster, 1 GB of system memory, as well as a DirectX 9 graphics adapter with WDDM 1.0 or higher driver, which you’ve shared with me that each of your workstations have. However, before you began the updating process you need to look at the hardware compatibility of you machines with the Windows 7 program.
